Improved synchronizer gear ring abrasion endurance testing machine and operation method thereof

Abstract

The invention relates to a synchronizer gear ring abrasion endurance testing machine which comprises a rack and a base (A), a motor component (B), a driving shaft component (C), a box body part (D), a dynamometer shaft and a cylinder component (E), a cylinder support component (F), a control cabinet (G), an oil temperature heating control component (H) and a data processing center. The synchronizer gear ring abrasion endurance testing machine has the advantages that by the improvement for the synchronizer gear ring abrasion endurance testing machine, a driving shaft can be separated from a motor by power, and the inertia of a flywheel is changed and the performance of a speed changing box during actual gear shifting can be actually simulated at the same time, so that the requirement of the original synchronization ring abrasion performance test can be met, and the requirements for different inertias of synchronization ring individual test can be met; therefore, the performance of a synchronization ring can be really tested under the working condition of actual inertia, and the synchronization ring is accurately evaluated.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to an improved synchronizer gear ring abrasion durability testing machine and an operation method thereof. Background technique [0002] With the further development of the automobile industry, the market competition has become increasingly fierce, the market has stricter requirements on product performance, and the product categories have become more diversified. At present, the bench test used instead of the commonly used in the industry is the wear and durability test machine of the synchronizer gear ring, which cannot accurately reflect the friction characteristics of the synchronizer ring in actual work. The inertia of each gear in the gearbox is different, and the friction coefficient of the test should also be different. However, the drive shaft of the testing machine and the motor cannot be separated during the test, and the inertia is large. It is a forced wear te...
