Description

Technical Field

[0001] The utility model relates to the technical field of automobile suspensions, in particular to a high-precision and high-strength automobile suspension structure. Background Art

[0002] The suspension structure of a car is an important part of the car. It connects the frame (or load-bearing body) and the axle (or wheel), and is responsible for transmitting the force and torque between the wheel and the frame. Its main function is to buffer the impact force transmitted to the frame or body by the uneven road surface, and reduce the vibration caused by it, so as to ensure that the car can run smoothly.

[0003] Common suspensions are mainly composed of three parts: elastic elements, guide devices and shock absorbers. The main function of the elastic element is to support vertical loads, mitigate and suppress vibrations and impacts caused by uneven roads. The function of the guide mechanism is to transmit force and torque, and also to guide and control the movement trajectory of the wheels. However, in this method, since the shock absorber arm is directly connected to the frame through bolts and bearings, its connection strength is low and it is prone to breakage. In addition, since the interior of the suspension frame is a hollow structure, its own structural strength is low and cannot meet the working requirements of the suspension. Therefore, a high-precision and high-strength automobile suspension structure is proposed. Utility Model Content
