Suspension is one of the important assemblies on modern cars. Its main function is to transmit all the forces and moments acting between the wheels and the frame (or body), and to alleviate the impact generated when the car drives on uneven roads. , Attenuate the vibration of the bearing system caused by this to ensure the smooth running of the car. Therefore, it is necessary to provide an elastic connection between the wheel and the frame or the body, relying on elastic elements to transmit the vertical load between the wheel or axle and the frame or the body, and relying on its deformation to absorb energy to achieve the purpose of buffering. After adopting elastic connection, the car can be regarded as a vibration system composed of suspension mass (i.e. sprung mass), non-suspension mass (i.e. non-sprung mass) and springs (elastic elements), which can withstand uneven roads and aerodynamics. And drive train, engine excitation. In order to quickly dampen unnecessary vibrations, the suspension must also include damping elements, namely shock absorbers. In addition, the connecting devices in the suspension that ensure the reliable transmission of all forces and moments between the wheel and the frame or the body and determine the displacement characteristics of the wheel relative to the frame or the body are collectively called the guiding mechanism. The guiding mechanism determines the movement trajectory and the change of wheel positioning parameters when the wheel is bounce, as well as the position of the front and rear roll center and trim center of the vehicle, thereby greatly improving the handling stability and anti-pitch ability of the vehicle.

Suspension is one of the most important components in modern automobiles, its main function is to transmit all the forces and torques acting between the wheels and the frame (or body), and to mitigate the impact of the car when driving across uneven road surface, attenuating the vibration of the carrying system caused by it, in order to ensure the smooth driving of the car. Therefore, an elastic connection must be provided between the wheel and the frame or body, relying on elastic elements to transmit the dying load between the wheel or axle and the frame or body, and relying on its deformation to absorb energy for cushioning purposes. With elastic connections, the car can be thought of as a vibration system consisting of suspension mass (i.e. reed load mass), non-suspension mass (i.e. non-reed load mass) and spring (elastic element), which is stimulated by uneven road surfaces, aerodynamics and transmission systems, and engines. In order to quickly attenuated unnecessary vibrations, the suspension must also include a damping element, the damper. In addition, the connecting device in the suspension that ensures reliable transmission of all forces and torques between the wheel and the frame or body and determines the displacement characteristics of the wheel relative to the frame or body is collectively referred to as the guide mechanism. The guiding mechanism determines the change of motion trajectory and wheel positioning parameters when the wheels are beating, as well as the position of the center of the car's front and rear tilt and the center of the tilt, thus greatly improving the vehicle's handling stability and anti-tilt capability.

Suspension is one of the most important assemblies in modern automobile. Its main function is to transfer all the forces and moments between the wheel and the frame (or body), and to alleviate the impact of the vehicle when driving across the uneven road surface, and attenuate the vibration of the bearing system caused by this, so as to ensure the ride comfort of the vehicle. Therefore, it is necessary to provide elastic connection between the wheel and the frame or body. The vertical load between the wheel or axle and the frame or body should be transferred by the elastic element, and the energy can be absorbed by the deformation to achieve the purpose of cushioning. After adopting elastic connection, the vehicle can be regarded as a vibration system composed of suspension mass (i.e. sprung mass), non suspension mass (i.e. unsprung mass) and spring (elastic element), which bears the excitation from uneven road surface, aerodynamic force, transmission system and engine. In order to reduce the unnecessary vibration rapidly, the suspension must also include damping elements, namely shock absorber. In addition, the connecting device which ensures the reliable transmission of all forces and moments between the wheel and the frame or body and determines the displacement characteristics of the wheel relative to the frame or body is collectively referred to as the guiding mechanism. It improves the stability of the vehicle's steering mechanism when the vehicle's center and roll angle change greatly.<br>
