Abstract

The invention relates to a bench test device for vertical stress on a plate spring. The bench test device comprises supports, sliding plates, spring eye brackets, a plate spring assembly to be tested, a stress base plate, a base plate, a lower base plate, U-shaped bolts and a steel ball. By means of the bench test device for the vertical stress on the plate spring, the safety in the bench test process is guaranteed, and a stiffness characteristic test, a dynamic stiffness characteristic test and a fatigue test can be carried out; the influence of torque generated after inclination of the plate spring on the bench test is eliminated, distortion of the bench test is avoided, and the test method is scientific and precise; the vertical stress and movement of the plate spring are fully simulated, and the performance of the plate spring fully meets the demand of whole vehicle movement.

Description

technical field [0001] The invention belongs to the technical field of leaf spring detection, in particular to a bench test device for the upper and lower force of a leaf spring. Background technique [0002] Leaf springs (referred to as leaf springs) can be placed vertically or horizontally on the car. Because the horizontal leaf spring needs to transmit the longitudinal force, an additional guiding force transmission device must be provided, which makes the structure complicated and the mass increased, so it is only used in a small number of light and miniature vehicles. Longitudinal leaf springs can transmit various forces and moments, have a guiding function, and have a simple structure, so they are widely used in automobiles. [0003] Longitudinal leaf springs are divided into symmetrical and asymmetrical. If the distance between the fixed center of the middle part of the leaf spring on the axle (bridge) (here the bolt is called the center bolt) and the center of the ...
