[WapCar] I believe that everyone has the experience of looking through the color pages of vehicle promotion, in which the suspension structure is often a propaganda or described miraculous project, seemingly the same suspension structure to the mouth of different manufacturers, seems to be different.
In fact, the suspension is not that complicated, this time we will help you simplify it.
There are many ways to classify the suspension. This time we will classify them according to whether the wheel motions on both sides of the car are related. According to this evaluation standard, the suspension can be divided into two types, that is, independent suspension and non-independent suspension in two forms. In addition, at the end of the article, we will introduce the semi-independent suspension that is still slightly controversial.
At present, the more common suspensions are MacPherson independent suspension, double wishbone independent suspension, double widearm independent suspension, multi-link independent suspension, trailing arm torsion beam type non-independent suspension, and integral bridge type non-independent suspensions, etc., we will interpret them one by one according to the above classification method.
■Non-independent Suspension
Features: simple structure, reliable operation, long service life
As the name implies, the non-independent suspension structure is that the wheels on both sides are installed at both ends of an integral axle, and the axle is connected to the frame through elastic components. When one wheel bounces due to road conditions, it will affect the positioning parameters of the other wheel.
● Longitudinal Leaf Spring Non-independent Suspension
Representative models: micro-face, truck, bus
The elastic element in this suspension is not our common spiral spring, but a leaf spring installed longitudinally. The advantage of the suspension of this structure lies in its good bearing capacity. At present, this type of suspension is widely used in the front and rear suspensions of trucks, and of course, some hard-core off-road vehicles use this type of suspension.
● Coil Spring Type Non-independent Suspension
Representative model: Jeep Wrangler
Here, we do not attribute the trailing arm torsion beam that is often seen in the configuration table to the coil spring type non-independent suspension. We will put this part in the final interpretation.
