Adhere To The Innovative Concept Of "People Without Me, People With Me, People With New Me"
A brief introduction to semi-trailer suspension
A typical suspension structure consists of elastic elements, guiding mechanisms and shock absorbers, as well as cushioning blocks and transverse stabiliser bars in individual structures. The elastic elements include steel springs, air springs, coil springs and torsion bar springs, while modern car suspensions mostly use coil springs and torsion bar springs, and individual premium cars use air springs.
The suspension is a general term for all the force transferring connections between the frame and axle or wheels of a car, whose role is to transfer the force and torque between the wheels and frame, and to cushion the impact transmitted to the frame or body by the uneven road surface, and to attenuate the vibration caused by it, in order to ensure that the car can drive smoothly.
The suspension is an important assembly in the car, which links the frame to the wheels elastically and relates to the performance of the car in a variety of ways. From the outside, the car suspension is only composed of a number of rods, cylinders and springs, but do not think it is very simple, on the contrary, the car suspension is a more difficult to meet the requirements of the car assembly, this is because the suspension to meet both the comfort requirements of the car, but also to meet the requirements of its handling stability, and these two aspects are opposed to each other. For example, in order to obtain good comfort, need to greatly cushion the vibration of the car, so that the spring should be designed to be soft, but the spring is soft but easy to make the car braking "nod", acceleration "head up" and left and right side tilt serious bad tendency, not conducive to This is not conducive to steering and can lead to unstable handling.
Summary：
A typical suspension structure consists of elastic elements, guiding mechanisms and shock absorbers, as well as cushioning blocks and transverse stabiliser bars in individual structures. The elastic elements include steel springs, air springs, coil springs and torsion bar springs, while modern car suspensions mostly use coil springs and torsion bar springs, and individual premium cars use air springs.
