Problems solved by technology

However, there is still a lack of relevant test benches for the matching of the leaf spring suspension system.
At the same time, most of the stiffness tests of the axle housing are aimed at the bending stiffness and strength, and there is still a lack of test benches for the torsional rigidity of the axle housing.

Abstract

The invention relates to an integrated test bench for a spring plate spring suspension system, wherein the integrated test bench has advantages of diversified measuring functions and simple and convenient operation. The test bench comprises a tested piece system, a clamping system, a torque loading and measuring system, a rotation angle measuring system, a rear axle locking system, an alternating-current motor protection system, a torque loading and measuring system, a vertical loading system, and a vertical displacement measuring system. The test bench not only is capable of carrying out longitudinal angle stiffness and radial stiffness measurement accurately on a spring plate spring suspension system and dynamic testing on the spring plate spring suspension system but also can be used as a measuring test bench for matching of the spring plate spring suspension system and an axle and can carry out axle housing torsion rigidity and intensity testing by connection of the spring plate spring suspension system with the axle. The test bench is capable of carrying out a plurality of tests respectively; all test operation steps can be implemented simply and conveniently; and practicability is high.

Description

technical field [0001] The invention relates to the field of automobile leaf spring suspension tests, in particular to a comprehensive test bench for leaf spring suspension systems. Background technique [0002] Currently, rigs for measuring leaf spring stiffness are limited to radial stiffness. When testing the radial stiffness of the leaf spring, the leaf spring assembly is generally installed on the test bench, and one end of the leaf spring is fixed to the bench by a pin shaft to ensure its degree of freedom of rotation. The other end is connected with the sliding trolley through the pin shaft to ensure that it can rotate around the pin shaft and move automatically along the length direction. A load is applied to the leaf spring saddle bolt so that its radial stiffness can be measured. However, there is no test bench for measuring the longitudinal angle steel degree, radial stiffness and matching of leaf springs, swing lugs and axles of leaf spring suspension systems (...
