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 synchronizer

Example Embodiment

[0035] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail with reference to the accompanying drawings.

[0036] Such as Figure 1-8 As shown, the embodiment of the present invention provides a torque test auxiliary tool for a synchronizer, which is specifically used to test the reliability of the synchronizer sleeve 11 and the synchronizer hub 12 under a torque load. The torque test auxiliary tool includes a torque bearing wheel 21 and a torque input shaft 22. The torque-carrying wheel 21 includes a flange, a central shaft, and a gear sleeve fixing disc that are fixed in sequence. The flange can be fixedly connected to the test bench. The gear sleeve fixing disc can be fixed to the synchronizer sleeve 11 to be checked. The synchronizer The gear sleeve 11 meshes with the synchronizer gear hub 12 to be inspected. One end of the torque input shaft 22 is coaxial...

Abstract

The invention discloses a torque test auxiliary tool of a synchronizer. The torque test auxiliary tool of the synchronizer comprises a torque bearing wheel and a torque input shaft, wherein the torque bearing wheel comprises a flange, a middle shaft and a gear sleeve fixing disk which are fixed in sequence, the flange is capable of being fixedly connected with a test bench, the gear sleeve fixing disk is capable of being fixed to a synchronizer gear sleeve to be detected, and the synchronizer gear sleeve is in tooth engagement with a synchronizer gear hub; and one end of the torque input shaft is coaxially fixed to a power input shaft, and the other end is provided with a driving gear engaged with the synchronizer gear hub. According to the invention, the synchronizer gear sleeve and the synchronizer gear hub are engaged, the torque input shaft and the synchronizer gear hub are engaged, the power input shaft is enable to apply a dynamic and bidirectional load, and in this way, the reliability of a synchronizer is detected, and the production quality of the synchronizer is improved; in addition, the torque test auxiliary tool is capable of ensuring the production quality of the synchronizer in a synchronizer production process, so that the problem that the quality problem of the synchronizer is not found until in a complete vehicle test is solved, so that the manufacturing cost of an integral vehicle is lowered.

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...
