Problems solved by technology

However, the one-way test bench can only verify a single working condition, and the verification of complex working conditions such as the S deformation of the leaf spring is insufficient; it cannot fully use the real vehicle load spectrum to load, and cannot perform the equivalent conversion between the bench test and the road test
Some existing motion interference decoupling methods, most of which use extension rods to minimize motion interference in two directions, but do not perform very effective mechanical decoupling

Abstract

The invention discloses two-degree-of-freedom loading bench test equipment for a steel plate spring, which belongs to the technical field of automobile part tests. The two-degree-of-freedom loading bench test equipment for the steel plate spring comprises a frame clamp, an axle clamp and a steel plate spring, the axle clamp is fixedly connected to the steel plate spring, and the steel plate spring is movably connected to the frame clamp. The two-degree-of-freedom loading bench test equipment for the steel plate spring further comprises a vertical loading mechanism, a longitudinal loading mechanism and a vertical fixing mechanism, the vertical loading mechanism is used for loading a vertical load to the frame clamp so as to load the vertical load to the steel plate spring, and the longitudinal loading mechanism is used for loading a longitudinal load to the axle clamp so as to load the longitudinal load to the steel plate spring. One end of the vertical fixing mechanism is rotationally connected to the axle clamp, and the other end of the vertical fixing mechanism is rotationally arranged. According to the loading bench test equipment, vertical and longitudinal motion interference is effectively decoupled, and the loading accuracy in two directions is ensured.

Description

technical field [0001] The invention relates to the technical field of auto parts testing, in particular to a two-degree-of-freedom loading bench test equipment for leaf springs. Background technique [0002] Leaf spring is one of the most widely used elastic elements in the automobile suspension system. It is an important part that elastically connects the vehicle body with the wheel. The impact load on the body can attenuate the vibration caused by the impact load to ensure the normal driving of the vehicle. [0003] Due to the large vertical deformation of the leaf spring, when the leaf spring is loaded with two degrees of freedom, the movement interference in the two directions is relatively large, which affects the accuracy of the test loading. Therefore, most leaf spring test benches are one-way test benches, that is, vertical or longitudinal tests are performed separately. However, the one-way test bench can only verify a single working condition, and the verificati...
