Description

technical field [0001] The invention belongs to the field of clutch working state monitoring, in particular to a device for measuring real-time temperature and torque of friction plates of a dry clutch. Background technique [0002] The clutch is a key component of the automobile transmission system. Through the combination and separation of the clutch, the power transmission and interruption between the automobile engine system, the gearbox and the tires are realized. Dry clutches are simple and compact in structure, easy to disassemble and maintain, and can transmit relatively large torques. Therefore, many low-cost passenger cars and large commercial vehicles that need to transmit large torques are still widely using dry clutches. During the engagement process of the dry clutch, due to the relative slip between the clutch driven disc and the engine flywheel disc, a large amount of friction heat will be generated during the power transmission process, which will greatly in...
