Problems solved by technology

The axial fatigue testing machine must be used to carry out the fatigue test on the product to ensure the performance of the product. However, the existing axial fatigue testing machine only simply performs a single function test of tension or compression on the thrust rod workpiece, which has a single function and a complex structure.

Abstract

The invention relates to the field of automobile accessories, in particular to a novel axial fatigue tester. The novel axial fatigue tester comprises a workbench, a lower U-shaped connection base, an upper connection board, a support pole, an upper U-shaped connection base and a main oil cylinder, wherein the lower U-shaped connection base is arranged in the middle of the workbench; the upper connection board is arranged above the workbench; the support pole is arranged between the workbench and the upper connection board; the upper U-shaped connection base is arranged in the middle of the lower end face of the upper connection board; and the main oil cylinder is arranged on the upper end face of the upper connection board, and the lower end of a piston rod of the main oil cylinder is integrally connected with the upper U-shaped connection base. Due to the structure, the stretching and compression of a thrust rod can be realized, so that sinusoidal wave is realized, and the tester is convenient to use and simple in structure.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a novel axial fatigue testing machine. Background technique [0002] Automotive thrust rods are widely used in dual rear axle balance suspension and air suspension trucks and passenger cars to maintain the relative position between the two axles or between the axle and the frame, and to transmit the longitudinal and lateral forces of the car. Forces and moments in other directions can also be transmitted. The thrust rod of the car is mainly composed of a ball head and a sleeve in the axial direction through several corrugated bites to support the truck and passenger car, and is used to maintain a large axial force between the two axles or between the axle and the car. It is required to be able to withstand a certain torque T and tension F. The axial fatigue testing machine must be used to carry out the fatigue test on the product to ensure the performance of the product. However, the ...
