A visual test device for wet clutch

Abstract

The invention provides a wet clutch visualization testing device comprising a box body assembly, an input assembly, an output assembly and a control assembly; the box body assembly comprises a box body and a transparent box cover; the right end of the box body is a sleeve, the left end of the box body is an opening, and the transparent box cover is fixed on the left opening of the box body; an input shaft of the input assembly is rotatably assembled in the sleeve; an output shaft of the output assembly penetrates an input wheel hub and the input shaft, and is rotatably connected with the inputwheel hub and the input shaft; a high speed camera in the detection device is arranged outside the transparent box cover; a sensor is fixed in a corresponding sensor mount hole on the transparent boxcover. The transparent cover plate and a friction sheet can form a friction pair; the motion conditions of an oil film can be directly observed via the transparent cover plate; the detection device can detect the work performance of the wet clutch in real time.

Description

technical field [0001] The invention relates to a clutch testing device, in particular to a wet clutch visual testing device. Background technique [0002] The clutch is an important part of the automatic transmission system. The clutch is mainly divided into a dry clutch and a wet clutch. The heat generated by the slipping of the wet clutch during the engagement process can be quickly taken away by the cooling oil, which can effectively control the surface of the friction pair. temperature, thereby reducing surface wear, and is mostly used in gear shifting systems with heavy workload and frequent manipulation. [0003] While the wet clutch is being developed, it is also being continuously improved and updated. Therefore, it is necessary to conduct theoretical and experimental research on its structure, control and detection systems to further improve its performance.

Problems solved by technology

Hu Jibin of Beijing Institute of Technology disclosed a single-plate wet clutch test bench in January 2012 in the article "Experimental Research on Drag Torque for Single-plate Wet Clutch". Observe the oil film between the friction plates, but the passive end is fixed, so the output torque cannot be detected and the gap between the friction plates cannot be adjusted, and the oil splash on the main engine of the test bench will affect the observation effect
