Abstract

The invention discloses an automotive suspension intensity test bed, and the test bed comprises a frame, an actuator, a counter-force frame, and a wheel replacement part. Two opposite ends of the actuator are respectively connected with the counter-force frame and the wheel replacement part. The wheel replacement part is connected with the frame through an automobile suspension and a subframe. The frame is provided with an adjustment vertical column, and the subframe is fixed between the adjustment vertical column and the frame. The position of the adjustment vertical column on the frame can be adjusted in the first direction, and the positions of the subframe on the adjustment vertical column and the frame can be adjusted in the second direction. The wheel replacement part is provided with a plurality of installation surfaces in different directions, and the actuator is fixed on different installation surfaces under different testing demands. The test bed is suitable for different types of subframes in different sizes through adjusting the lateral position of the adjustment vertical column on the frame and/or the longitudinal position of the subframes on the adjustment vertical column and the frame, can select different installation surfaces of the wheel replacement part according to different testing demands, and achieves the testing of fatigue strength and static strength of different suspensions.

Description

technical field [0001] The invention relates to the field of automobile testing, in particular to an automobile suspension strength test stand. Background technique [0002] Automobile suspension mainly includes components such as shock absorbers, elastic elements, and guide mechanisms. function to ensure the smooth running of the car. When the vehicle reaches a certain service life, the components such as the shock absorber and the swing arm in the suspension may be fatigued and fractured; Breakage may occur due to insufficient strength. The above all affect the safety of the vehicle, so it is necessary to carry out fatigue strength and static strength tests on the suspension to verify whether it meets the design requirements. [0003] During the driving process of the vehicle, the suspension is usually subjected to various loads such as driving force, driving resistance, braking force, and impact on uneven roads. These loads can be simplified as figure 1 The force mode...
