Double wishbone independent suspension
The double wishbone independent suspension of Mercedes-Benz CLS is not the double wishbone in the traditional definition, because the lower swing arm uses two control arms. The advantage of replacing the lower arm with two lower arms is to move the hinge point of the virtual caster angle of the front tire, so that the caster angle of the kingpin is enlarged and the handling performance of the vehicle is improved.
At the same time, people can also notice that the upper control arm, the lower adjustment arm, the steering tie rod and its horizontal support rod are all made of aluminum alloy. Compared with the traditional stamping die thick steel plate, the aluminum alloy profile is stronger and lighter, which reduces the unsprung weight and is beneficial to improve the handling performance of the vehicle.
Connecting rod rear suspension system
The rear suspension system of Mercedes-Benz CLS adopts connecting rod structure, which has the advantage of improving the handling performance and comfort of the vehicle. But the disadvantage is that the cost of suspension system is high, the main parameters are difficult to adjust accurately, and the maintenance cost will increase in the middle and late stage. However, it can be noted that starting from the 20 18 Mercedes-Benz CLS, the whole system is not equipped with shock absorbers, but the market price is correspondingly low.
Electric power steering
The power-assisted system software of Mercedes-Benz CLS is powered by motor. Its advantage is that it can adjust the level of power-assisted, which is very friendly to girls. At the same time, there is no need to change gear oil regularly like the traditional hydraulic press, and the maintenance cost in the middle and later stages is extremely low.
However, electric power assist also has some disadvantages, that is, the energy is limited, and it will enter the motor safety mode if it works at full load for too long. At this time, the boost will drop sharply or even fade, and the boost can only be repaired after the motor cools down. Therefore, it is generally impossible for hard-core off-road vehicles to apply electric power steering.
In addition, the power steering of CLS also includes the function of variable steering ratio. When the vehicle is in a low gear, the wheels will shake a large angle of view only by moving slightly, making the vehicle more flexible; But even if the steering wheel is turned at high speed, the viewing angle of the wheel is still very small, which improves the rapid reliability of the vehicle.
Mercedes-benz 4MATIC four-wheel drive system
Mercedes-Benz CLS is equipped with 4MATIC full-time four-wheel drive, which can realize the driving force distribution of 45: 55 in front, rear, left and right under all normal road conditions. The double-plate clutch central differential will fuse when the wheel falls off to ensure that other tires have driving force. At the same time, the 4ETS technology of Mercedes-Benz 4MATIC will stimulate ABS pump to brake the wheels of off-road vehicles to ensure the vehicle's grip on cultivated land.
It is worth mentioning that the structure of this 4MATIC system software is very compact and lightweight, only about 70KG heavier than the front and rear drive model. At the same time, the consumption of driving force is also suppressed to the minimum, which makes the net weight distribution and fuel rationality of Mercedes-Benz CLS particularly excellent.
Generally speaking, although the appearance design of Mercedes-Benz CLS is very healthy, its chassis structure is more inclined to comfort. Because Mercedes-Benz itself is very clear, people who buy CLS just want a family car with a very healthy appearance, so it is enough to consider the appearance. If the chassis of the car is also adjusted for exercise, the driving feeling of the whole car will be very poor during normal exercise.
