Problems solved by technology

[0002] In the test standards of automobile transmissions, the whole transmission is tested, and the shift fork components in the transmission are not tested separately. Generally, the fatigue test of the shift fork is carried out together with the synchronizer, but when the synchronizer is tested, the entire load The working condition is designed for the synchronizer, and it cannot really test the fatigue limit and safety reserve factor of the shift fork, and the synchronizer test is carried out synchronously for the test of the shift fork. The test cost is high, the experimental process is complicated, and the test data is reliable. low degree

Abstract

The invention discloses a fatigue life testing device of a car gear shift lever shifting fork. The fatigue life testing device comprises a base, a shifting fork driving mechanism arranged on the base, rolling bearings symmetrically arranged at the two ends of the shifting fork driving mechanism, a stopping block and a resistance air cylinder. The shifting fork is arranged on the shifting fork driving mechanism. The shifting fork is connected with a sliding shaft which is supported through the rolling bearings. The resistance air cylinder is connected with an air cylinder piston rod, a force sensor and a pressing disc. The whole fatigue life testing device of the car gear shift lever shifting fork is novel in structure, a testing process is simple, testing results are reliable, and cost is low.

Description

technical field [0001] The invention relates to a fatigue life testing device, in particular to a fatigue life testing device for an automobile transmission lever shift fork. Background technique [0002] In the test standards of automobile transmissions, the whole transmission is tested, and the shift fork components in the transmission are not tested separately. Generally, the fatigue test of the shift fork is carried out together with the synchronizer, but when the synchronizer is tested, the entire load The working condition is designed for the synchronizer, and it cannot really test the fatigue limit and safety reserve factor of the shift fork, and the synchronizer test is carried out synchronously for the test of the shift fork. The test cost is high, the experimental process is complicated, and the test data is reliable. low degree. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, and provide a fat...
