The Importance of Suspension and Steering Components to Cars

The special mechanism used to change the driving direction of the automobile is collectively referred to as the automobile steering system. ), steering assist mechanism (steering pump, steering motor), etc. The function of the car steering system is to ensure that the car can run in a straight line or turn according to the driver's wishes. It cooperates and coordinates with the suspension system of the car and directly affects the handling of the car.

Nowadays, most of the steering systems of automobiles have power assist devices, generally there are two kinds of hydraulic power assist and electric power assist. The electric power steering system is mostly used in passenger cars. It has the characteristics of speed-dependent steering, which can make the car have better handling, but its disadvantage is that the power assist is small; and hydraulic power assist is mostly used in trucks and off-road vehicles. Steering system, its power assist is larger, and its performance is more stable and reliable. The disadvantage is that it increases the engine load and cannot change the size of the power assist with the speed of the vehicle.

Nowadays, ordinary family cars basically pursue comfort. In this way, the adjustment of its suspension system should be softer, with better shock filtering, and the road feeling is not very clear. Good under-steering characteristics are the mainstay, and the braking system is sluggishly adjusted; for performance cars, it pursues good handling, so the suspension system needs to be harder, the steering system feels heavier and more precise, and the control The dynamic system is also more responsive, and so on. And some more advanced models, in order to achieve the unity of comfort and good handling, will also use an active suspension system, according to the speed and road conditions, automatically adjust the hardness of the suspension system and the steering system. feel, etc.
