From July 1st, the newly -branded vehicle must be the National Five Model. In response to this policy, car companies at home and abroad have launched their own national five products. Scania also switched its own products in the first half of this year and launched the National Five Series models. Today I will introduce a high -end R450 tractor with a national five version.

StreamLine cabinet naming lights

The real shot of this National Five version of Scania uses the R series Streamline cab, the model is R450. Compared with our common G series, the R series cab is not different from the G series cab. Large, the cover of the cab is very universal, and the difference is mainly in the configuration of the cab.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

From the top to bottom, there is a sign of the Streamline on the top of the cab, proves that the car cabin is a Streamline version. Compared with ordinary cab, the Streamline version of the cabin has greater and more beautiful.

In addition, because this car is a high -profile model, there are LED spotlights on both sides of the sunboard, which can be used as a display light, or it can be used with the light group in the middle of the sunboard as a lighting light. In addition, the lower edge of the shading plate is painted with black and black and white, making the entire sunnate more layered and improved a lot of face value.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

The angles on both sides of the windshield are also relatively round. This design benefit is that the wind resistance during driving can be reduced, and a lane offset reminder system is installed in the middle of the windshield. If the driver deviates from the driving lane during the driving process or other reasons, the system will issue an alarm. This can improve the driving safety of the vehicle, which can prevent the driver from doze, and indirectly increase the vehicle’s attendance rate.

The bumper can flip the halogen bulb

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

The rearview mirror of the Scania model is also very distinctive. The rearview mirror adopts a split design, the main mirror is below, and the auxiliary mirror is above. And the above -mentioned sub -mirror uses a convex mirror. This design allows the driver to observe the situation on both sides of the vehicle. After personal experience, Scania’s rearview mirror can basically achieve no dead ends on both sides, and the rearview mirror on the rearview mirror. The wind noise is very small. These small details are where our domestic car is worth learning.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

The front cover is the most obvious sign of Scania. There is a large “Scania” logo on the upper part of the front cover, and there is a “badge” on the right. I have a urge to pull him down.

In addition to the large logo, the front cover and the pedal in the middle of the front cover form a whole, using a cross -type design. This design not only guarantees the amount of air inlet, but also reduces materials and reduces weight. In addition, there is no designed air guide slot on both sides of the Scania cab, only a soft wind lip on each side, the function, effect, and the air guide slot are consistent.

Finally, let’s talk about the bumper. The bumper of this G450 is painted with black. The bumper is relatively rounded on both sides. The middle part of the bumper is a flip design, and the aluminum alloy material is made of aluminum alloy. After turning, the driver can step on the front windshield on it. The front trailer hook is also hidden behind the bumper.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

Seeing the headlights, some card friends will definitely say that Scania is a bit unkind. All the headlights use halogen bulbs without lens. The biggest benefit of such design is that it is more convenient to replace and the cost is relatively low. As for the brightness and durability that everyone considers, don’t worry about it.

Small details humanized full -foot skirt plate reduces wind resistance

I once thought that Kayou said: “The current car configuration is almost the same, and the people who buy a car are more about small details.” Some of the small details of this Scania R450 are very good. First of all, talk about the turning lights we often use. Scania set up a turning light below the car pedal of the cab. This The turning light is protruding from the direction, and the direction is backward. This advantage is to give a prompt to the two sides of the vehicle or the vehicle behind to prevent accidents.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

In addition, Scania’s pedal pedal is also exposed directly outside. The pedal is designed with punching non -slip design and the material is aluminum alloy. There are also some differences in the angle of each level of the pedal, forming a small staircase design, which is convenient for drivers to enter the cab.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

Scania’s original diversion design is also very good. The derivative board on one side can be folded, which is convenient for drivers to connect trachea, cables, and so on. And at the end of the diversion cover, it is still a soft material, which can not be adaptable to the pressure of the air flow at the speed of the air flow and reduce the wind resistance and fuel consumption.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

We often take butter when maintaining vehicles, but some places are very biased with lubricating oil and injection. In order to solve this problem, Scania designed the extended tube for these more biased puppets. When maintaining the butter, it can be directly injected by extending the tube, which is very intimate.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

As a high -end car, if there is no side skirt board, I am embarrassed to drive out. This R450 is equipped with a side skirt. The original side skirt board and the entire vehicle are very coordinated. The side parcel is tightly wrapped, so that the wind resistance of the entire chassis can be reduced and fuel consumption.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

There is also a detail on the chassis that makes me feel very intimate. There are several stainless steel covers on the upper part of the frame. In addition to protecting the components in the middle of the frame, these cover boards can also allow the driver to step on the connection pipeline on it, which is very convenient.

Driving indoor black tone is the main steering wheel adopts pneumatic adjustment

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

The first feeling of pulling the door of the cab is luxurious inside the cab. The entire interior is mainly black tone, and the top is beige. This matching skill reduces the driver’s visual fatigue and is very dirty.

The R450 door is also relatively characteristic. There is a storage tank on the door to prevent water cups, small parts, etc., and there is a red warning sign outside the storage tank. You can see the red warning mark, which improves safety.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

Ascend the cab and sit on the seat. The airbag seats rose automatically. Although this car is a high -profile model, the seat is not the highest. The seats are only regulated, height, one -click filling, and waist adjustment. Users can also choose seat ventilation, heating, and so on.

Scania’s steering wheel adjustment is also very interesting. There is a switch below the steering wheel. After unlocking, the steering wheel can be adjusted up and down, back and forth. When you get out of the car, press the button. The steering wheel can be automatically moved forward, which is convenient for the driver to get off the car. The steering wheel is adjusted to the pneumatic help, which is very easy.

The operating switch button is the main block under the steering wheel

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

Looking at the cab, there are many keys on the entire center console. This is also a characteristic of Scania. Each button has its own only function. This design can prevent errors.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

I personally think that Scania’s steering wheel is also the most beautiful of many models. The steering wheel uses four -spoke design and is equipped with multi -function keys. The keys on both sides are controlled by the multimedia system, and the keys below the steering wheel are controlling fixed -speed cruise, downhill speed, and so on.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

In addition, the grip of the steering wheel is also very good, and the size is more moderate for me. Scania’s shift operation handle is also installed on the right side of the steering column, and the shifting handle integrates gearboxes and liquid slow speeder operations. The driver only needs to twist the handle gently, and the slower control is pulled down the handle, simple light.

The entire center console of Scania is protruding outward, but the protruding part is not particularly large. This design has the advantage that it is convenient for the driver to operate various keys on the center console, especially when driving when.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

The instrument of this R450 is consistent with the ordinary G series instrument. The two big and two small and a LCD screen in the middle can view all the information of the vehicle, including turbine pressure, cruise mileage, urea, fuel, etc. The situation, and the display rate is also more delicate.

It is also worth mentioning that this R450 is also equipped with a CD player. The current G series has been canceled, and users need to choose. At the same time, there is a simple folding small table board on the center console on the side of the co -driver. It is convenient to sign or place some other things after expanding.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

Although this R450 cab is a Treamline version, the cab is still not a flat floor. The floor between the main driver and the co -driver is a bit raised, but the height of the raisedness is not particularly large.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

For those who love the floor, this raised is a bit embarrassing, but in order to alleviate this embarrassment, Scania deliberately made a specific design. When the main and auxiliary seats are at the lowest, the seat and the raised position are just flat, and you can sleep.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

In order to increase the storage space of the cab, a drawer -type storage box is designed under the sleeper. The storage box can put some simple small objects, drinks or small pieces of clothes. And there is a cup holder near the side of the driver, which is very intimate.

In addition, there is a “foot basin” in the central part of the center console, but it is not washed the driver’s feet, but a storage compartment, which is convenient for placing some notes and cigarettes.

The sleeper hidden mystery can also control the car buttons

One of the experiences that have experienced Sknania have a sense of sleeper width, but this R450 sleeper hidden mysteries. During the rest, the main driving and the co -driver seats move forward, and the sides of the sleeper can be pulled out. In this way, the width of the sleeper has increased a lot, which is also a unique design of Scania.

In the models I have experienced, Scania’s sleeper is relatively comfortable. Whether it is supportive or materials, it is a better level. Scania’s sleeper comfort is equivalent to Mercedes -Benz sleepers. Of course, this is the feeling under the static experience.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

In addition, the reading lights are also installed on both ends of the sleeper. When the driver is resting at night, you can directly use the reading light to see the information or other things. In addition to reading the lights, there are charging ports, light control keys, sunroof switchs, etc., drivers and passengers can control the lights of the driver’s room when lying down and rest in the sleeper.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

In order to adapt to high -efficiency logistics long -distance transportation, this R450 cab is designed with multiple storage tanks and storage compartments. In addition to the below the sleeper introduced earlier, there are multiple storage compartments on the top of the cab and both sides. Some of the drivers’ washing products, changing clothes, etc. are greatly improved, which greatly improves the cleanliness of the cab.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

As the second home of the driver, the cabin must be good. Scania can be said to have a lot of effort in terms of comfort. The first is the sound insulation of the cab. After the door is closed, the two people in the cab can be heard. Coupled with the wind noise control of rear -view mirrors and shading plates, it can be said that the sound insulation effect of the Scania cab is equivalent to ordinary household cars.

The second is the comfort of rest. Scania sleeper is very supportive, hard and hard, and the driver and passenger personnel have a more comfortable rest environment whether it is driving or stopping in a parking state.

Furthermore is the convenience and small details of the operation. This R450 central control uses a full key operation and is very convenient to operate from the driver. Coupled with the AMT gearbox and a fixed -speed cruise, it greatly reduces the driver’s driving intensity.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

This R450 is also equipped with automatic air conditioning, electric sunroof, etc. These configurations seem to be very routine, but the configuration of such small details can provide convenience for the driver and improve the driver’s driving comfort.

National Five DC13 engine XPI high -pressure co -track technology

Because of the upgrading of emission regulations, Scania has also been upgraded from the original national fourth to the five of the country. Compared with the national fourth engine, the Staconia engine of the National V. XPI technology. And the National Five of the National Five of the National Five is Scania’s Ou Six Standard machine, but it only obtained the domestic fifth certification directly in the country.

The R450 is equipped with a machine with DC13 147. From the model, you can know that this machine is a product of Stannia 13L. The actual displacement is 12.742L, the maximum power is 450 horsepower, and the maximum torque is 2350 Nm. Essence

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

The engines carried by Scania’s domestic models have used pump nozzle technology, but the current national fifth engine uses high -voltage co -track, and Scania’s XPI technology can reach 2400Bar Essence Such a high jet pressure can improve the atomization effect of diesel, achieve the effect of fuel -saving, and reduce pollutant emissions.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

According to Starnia, the national fifth engine sold in China is the same as the European six engines used in Europe without any reduction. It is the calibration and certification of the National Five directly with the Ou Liu’s engine. In addition to the National Five, this engine is currently certified by Beijing Five. It can be seen that Scania attaches great importance to the Chinese market.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

Anyone who drove Scania knew that the Scania engine did not mobilize the mechanism, only exhaust braking. Scania’s exhaust braking is also very intelligent and efficient, and the design is also very interesting.

There are two ways to control the exhaust braking of Scania. One is to start the exhaust braking through the switch on the center console. At this time, the exhaust braking is only activated. Dynamics has a certain relationship with the engine speed.

The second way is to step on the switch next to the clutch pedal after starting the exhaust brake through the central control switch. At this time, the gearbox will be mandatory to improve the speed of the engine to improve the braking efficiency.

Therefore, a engine speed detection module is designed on the back end of the engine to detect the speed of the engine in real time, and this module has a control pipeline to directly control the exhaust braking. And when the engine speed is lower than a thousand rpm, the module will control the exit of exhaust braking to prevent the engine from loading the engine.

AMT gearbox modular design

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

As a transmission device for mobilizing power, the quality of the gearbox directly affects the performance of the vehicle. This R450 is equipped with Scania’s autonomous AMT gearbox with 12 forward gears and 2 reversing. This gearbox adopts a modular design, which greatly reduces the failure rate.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

What is modular design? It can be seen from the structure that the shift mechanism with similar structures similar to a manual transmission in the upper part of the gearbox means that this gearbox can be changed to a pure manual transmission. And there is a clutch oil pot next to the clutch. This design can reduce the distance between the oil pot and the clutch split pump, and this is also a modular design.

The advantage of modular design is that all parts are modular structures, such as shift mechanisms. AMT and manual gear are just different executive agencies. At the same time, after modularization, the number of parts has been greatly reduced, and the failure rate will be indirectly reduced. However, if a failure occurs, it may face high maintenance costs.

In order to improve driving safety, this R450 also equipped with a liquid force slower, and the official information introduces the brake torque of the slower speed device to exceed 4,000 Nm. The first gear of the slow speed device is the constant speed gear, and the 2-5 gear increases by 20%of the torque per gear, and the AMT gearbox will be added and subtracted according to the working state of the slow speed device to ensure the heat dissipation of the slower speed device. Effect.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

As for the smooth shift of the gearbox, I drove the front of the car to experience a small section of road, twisted the shift handle gently, and released the handbrake, and the car slowly started to move forward. When stepping on the accelerator, the system will shift shifts according to the current speed, engine speed, etc. When shifting, there is basically no obvious sense of frustration, only to feel that the engine speed has changed significantly.

It can be said that this AMT gearbox of Scania is already equivalent to ordinary car -shifting smoothness, and this gearbox is very smart. Add or subtract.

6×2 Drive 5 airbag suspension high -horsepower+small speed ratio than positioning efficient logistics

We said earlier that this car is positioned as high -efficiency logistics. Since it is high -efficiency logistics, one of the important ingredients is “fast”, fast speed, fast loading and unloading, and so on. In order to meet the fast speed, this vehicle power chain uses a structure of high horsepower+small speed ratio. Therefore, the rear axle speed ratio is only 2.71.

Parents will find that the driving bridge head of the Scania car is relatively special and protruding outwards. This is also a sign of the Scania Bridge. This structure is called a suspended semi -axis, which is to improve the durability and comfort of the bridge.

5气囊悬挂+AMT变速箱+国五 这款斯堪尼亚为何没有尿素罐?

The suspension uses Scania’s 5 airbag suspension. Each bridge has two airbags responsible for loading, and a airbag in the middle of the third axis is responsible for improving the third bridge. In addition to improving comfort, another advantage is that it is more convenient to connect and leave the trailer.

The configuration of the high -horsepower+small speed ratio makes the economic speed of this car is relatively high. For the current weight limit of 49 tons, this configuration does not need to worry about motivation at all.

The large dual fuel tank urea tank is “disappeared”

In order to improve the battery life of the vehicle, this R450 is equipped with dual fuel tanks. This can reduce the time on the road on the road. Secondly, it can ensure the oil products and avoid adding some inferior diesel because of worrying about the battery life.

In order to make room for dual fuel tanks, batteries, gas storage tanks, urea tanks, etc., which were originally installed on both sides of the chassis, were moved to the middle of the frame, and the battery was installed at the tail of the frame. It is particularly interesting that the urea tank is installed on the bottom of the car. It is located in front of the driving bridge and only leaves an additional injection outside. If you don’t pay attention, you can’t see where the urea tank is.

In addition to the middle of the frame, two air storage tanks are installed on the stent in the middle of the mud, and two other are installed on the rear of the frame. The battery is also installed at the rear of the frame, so that the chassis space is fully used. In the case, the space of the dual fuel tank is left, and the chassis also looks fuller and compact.

This vehicle is also equipped with EBS system to improve the vehicle braking safety. Especially when the vehicle appears side sliding, the EBS system can adjust the braking force of each wheel to prevent accidents. In addition, the whole car uses disc braking, the brake film is equipped with wear alarm, the disc braking is better than the drum brake heat dissipation, and the braking power is more linear.
