Abstract

The invention relates to a testing device and test method for a peeling torque of a synchronization ring. The testing device comprises a test stand, a support part arranged at the test stand, a rotating shaft, a torque transducer, a mounting groove, and a drive unit. The rotating shaft arranged at the support part has a first end and a second end. The torque transducer fixedly connected with the rotating shaft is used for testing the torque of the rotating shaft. The mounting groove formed in the test stand is used for installing a synchronization ring and a gear wheel cooperating with the synchronization ring; and the mounting groove and the rotating shaft are opposite to each other along the axis during testing. The drive unit is used for driving the rotation motion and the motion along the axis direction of the rotating shaft. With the testing device, the peeling torque of the synchronization ring is tested and thus a proper synchronization ring friction material and a proper design structure are selected based on the test value, so that a problem of gear shifting clamping caused to too large peeling torque is solved based on the improved design.

Description

technical field [0001] The invention relates to the technical field of automobile transmission synchronizers, in particular to a synchronous ring stripping torque test device and a test method. Background technique [0002] The function of the transmission synchronizer is to complete the gear shift under the condition of ensuring the synchronization of the speed, which can avoid the occurrence of gear shifting and shift shock. The synchronizer is mainly composed of an adapter sleeve and a synchronization ring. The role of the synchronous ring is to synchronize the speed of the input end and the output end through the friction torque generated by the friction material inside the synchronous ring. The size of the friction torque directly affects the shift performance. If the friction torque is small, the synchronization process cannot be completed, resulting in gear shifting; if the friction torque is large, it is easy to cause the friction cones to lock and not separate, and ...
