Clutch torque measuring device

Abstract

The invention discloses a clutch torque measuring device. The clutch torque measuring device comprises a testbed, a low-speed hydraulic motor, a clamping air cylinder and a telescopic cylinder, a positioning disc is fixedly mounted on the upper surface of the testbed, a plurality of pin holes are formed in the positioning disc, support blocks are detachably mounted in parts of the pin holes, a circumferential guide rail is fixedly arranged on the upper surface of the testbed, the telescopic cylinder capable of sliding along the guide rail is arranged above the circumferential guide rail, and apressing head is connected onto a movable rod of the telescopic cylinder. The clutch torque measuring device has the advantages that by adopting the low-speed hydraulic motor, a driven disc is enabled to rotate automatically to simulate an actual operation environment, the problem that a connection lever and weights of an existing stage testbed are mounted manually is solved, a workbench is designed into a horizontal plane, a clutch assembly can be mounted and dismounted conveniently and quickly, the problem that the clutch assembly is hard to mounte in the stage testbed is solved, and by adopting a torque sensor to measure a torque value, the maximum value of static torque can be measured precisely, and errors of weight measurement are decreased.

Description

Technical field [0001] The invention belongs to the technical field of clutch performance testing equipment, and in particular relates to a device for clutch torque measurement. Background technique [0002] The torque measurement of the clutch assembly is now measured by the clutch assembly bench test rig. By putting the clutch in a combined state, fixing either end of the primary and secondary driven shafts, connect the lever at the other end to slowly load until it slips. This method requires a small crane to lift the clutch assembly for measurement on the bench test bench, manually fix it on the vertical simulated flywheel with 12 long screws, insert a splined spindle, and connect to the bench test The main and auxiliary slave shafts of the bench move one end of the bench test bench to make the clutch assembly in the combined state, and use the connecting lever to increase the weight to achieve the slip state. The measurement error is large, and the accuracy of the measuremen...

AI Technical Summary

Problems solved by technology

This method needs to use a small crane to lift the clutch assembly due to the measurement of the bench test bench, manually fix it on the simulated flywheel in the vertical direction with 12 long screws, insert a main shaft with splines, and connect it to the bench test The main and auxiliary driven shafts of the bench move the end of the test bench to make the clutch assembly in the combined state, and use the connecting lever to increase the weight to achieve the slipping state. The measurement error is large, and the accuracy of the measurement data is greatly reduced.
