Description

Technical Field

[0001] The utility model belongs to the technical field of shock absorbers, and in particular relates to a lateral force loading mechanism of a shock absorber. Background Art

[0002] In the suspension system, elastic elements are subjected to vibrations due to impacts. In order to attenuate the vibrations and improve the smoothness of the car's ride, shock absorbers need to be installed in parallel with the elastic elements in the suspension. In actual use, the shock absorbers will be subjected to lateral forces due to the load of the usage scenario or some design and production issues. When the shock absorbers are subjected to lateral forces for a long time, the friction between the piston rod and the inner tube will increase. Over time, the sealing of the shock absorbers will be affected, and even oil leakage will be caused, affecting their use.

[0003] In order to eliminate the influence of the lateral force of the shock absorber, one approach is to set a loading mechanism on the side of the shock absorber, and use the loading mechanism to offset the lateral force on the shock absorber to keep the force on the shock absorber stable. In this approach, it is necessary to first experimentally measure the size of the lateral force on the shock absorber during operation, and then use the loading mechanism to accurately balance the lateral force on the shock absorber. Therefore, it is very necessary to design a recording mechanism that is easy to install and can accurately apply lateral force. Utility Model Content
