Abstract

An automobile test bench comprises a portal frame, at least one group of actuator, a clamp mechanism and a supporting mechanism which supports the structure of the whole test bench, the clamp mechanism is respectively connected with the actuator and the supporting mechanism and used for fixing a test article, the actuator is movably installed on the portal frame and comprises a sliding mechanism, an actuating cylinder and spherical hinges, wherein the sliding mechanism is installed on a beam of the portal frame, the spherical hinges are arranged at the upper and lower ends of the actuating cylinder, the sliding mechanism is connected with the actuating cylinder through the upper end spherical hinge, and the clamp mechanism is connected with the actuating cylinder through the lower end spherical hinge. The actuator is connected through the gapless spherical hinges, the problem of resonance vibration caused by fit clearance is eliminated, moreover, the actuating cylinder is capable of moving, convenience of the installation of the test article is increased, and working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of automobiles, relates to the field of testing of automobile parts, in particular to a bench test stand. Background technique [0002] Before the automobile products leave the factory, some simulated bench tests are generally carried out. The so-called bench test refers to putting the tested parts on a specially designed bench for testing to check whether the performance of the tested parts meets the specified standards. , the test piece can only be put into use after passing the test bench test. Common bench tests include some engine tests, automobile rear axle tests, etc. In the automobile rear axle test, it is often necessary to use the automobile rear axle test bench to simulate the loading test of the car under road driving conditions or specific working conditions. [0003] In practice, the bench test has gradually become the main means of test verification for various automobile companies due to its advantage...
