Bushing torsion test tool

Abstract

The invention discloses a bushing torsion test tool which comprises a mounting base and a pressure block, wherein a mounting hole for mounting a bushing is formed in the front side surface of the mounting base; a sensor is fixedly arranged above the mounting base; the pressure block is located above the sensor; a threaded hole is formed in the center of the pressure block; a bolt is arranged in the threaded hole; one end of the bolt pushes against the sensor; a front tie rod ball and a rear tie rod ball are respectively arranged on the front side and the rear side of the mounting hole; the front tie rod ball and the rear tie rod ball are the same in structure; the front tie rod ball comprises a circular ring element and a connecting pole; the upper end of the circular ring element is connected with the pressure block through the connecting pole; a connecting rod is arranged on the front tie rod ball; one end of the connecting rod is in a cylindrical structure, sequentially penetrates through the front tie rod ball, the mounting hole and the rear tie rod ball and finally is fixed; and the other end of the connecting rod is of a cuboid structure and used for connecting a power device. The bushing torsion test tool is simple in overall structure and low in cost; a predetermined load can be accurately applied to the bushing; and then the torsion test is carried out on the bushing.

Description

technical field [0001] The invention relates to the technical field of testing equipment for auto parts, in particular to a tool for torsion testing of bushings. Background technique [0002] Bushing is a commonly used shock absorbing structure in automobiles. Its main function is to control the movement displacement of powertrain, vibration and noise in the car. With the improvement of people's quality of life requirements, the requirements for the vibration isolation performance and sound insulation performance of the vehicle are getting higher and higher. Therefore, the fatigue performance of the bushing has a very important influence on the performance of the vehicle. [0003] Nowadays, the automotive industry has higher and higher requirements for components, and now the bushing is required to undergo a new test experiment before leaving the factory: apply a load in the radial direction of the bushing and perform a torsion test on the axial direction. However, none of...

AI Technical Summary

Problems solved by technology

However, none of the equipment used to test the torsion test has the function of applying load in the radial direction

However, adding radially applied load equipment to the original torsion test equipment will lead to an increase in the structural volume of the entire equipment, an increase in cost, and inconvenient operation
