Auxiliary Tooling for Torque Test of Synchronizer

Abstract

The invention discloses a torque test auxiliary tool for a synchronizer, comprising: a torque bearing wheel, the torque bearing wheel includes a flange plate, a central shaft and a gear sleeve fixing plate fixed in sequence, and the flange plate can be fixedly connected with a test bench, The gear sleeve fixing plate can be fixed with the synchronizer gear sleeve to be inspected, and the synchronizer gear sleeve is meshed with the synchronizer hub gear to be inspected; the torque input shaft, one end of the torque input shaft is coaxially fixed with the power input shaft, and the other end is Has drive teeth that mesh with the synchronizer hub. Because the gear sleeve of the synchronizer meshes with the gear hub of the synchronizer, and the torque input shaft meshes with the hub of the synchronizer, the power input shaft can apply dynamic and bidirectional loads, so as to test the reliability of the synchronizer, and then improve the production of the synchronizer Quality; at the same time, with the above torque test auxiliary tooling, the production quality of the synchronizer can be guaranteed in the production process of the synchronizer, so as to prevent the quality problem of the synchronizer from being discovered during the vehicle test, thereby reducing the manufacturing cost of the vehicle.

Description

technical field [0001] The invention relates to the technical field of synchronizer processing, in particular to an auxiliary torque test tool for a synchronizer. Background technique [0002] In a gearbox with a synchronizer, the reliability of the synchronizer will directly affect the shift performance, comfort and safety of the gearbox. Therefore, at present, when producing synchronizers, it is necessary to evaluate the reliability of the synchronizers to ensure the above-mentioned performance of the gearbox. [0003] In the traditional technology, the reliability test of the synchronizer is mainly aimed at the torque transmission reliability of the synchronizer. There are two specific verification methods as follows: [0004] The first is to verify the reliability of the synchronizer under static and one-way load in the worst gear in the static torsion test of the gearbox. [0005] The second is to verify the comprehensive reliability of the synchronizer in the vehicle...

AI Technical Summary

Problems solved by technology

[0006] Although the first method has verified the reliability of the synchronizer under static and one-way loads in the worst gear, the parts are subjected to dynamic loads in actual work, so this method does not consider the impact of alternating impact loads on the synchronizer. Reliability impact, resulting in poor production quality of synchronizers

[0007] In the second method, the whole vehicle test cannot guarantee that the synchronizer is in the worst working condition; and the whole vehicle test should be carried out after the component test is verified to be qualified. The manufacturing cost is too high; in addition, the vehicle test is protracted, the cycle is long, and the efficiency is low
