[0002] The clutch is located in the flywheel housing between the engine and the gearbox. The clutch assembly is fixed to the rear plane of the flywheel with screws. The output shaft of the clutch is the input shaft of the gearbox. During the driving of the car, the driver can step on or release the clutch pedal as needed to temporarily separate and gradually engage the engine and gearbox to cut off or transfer the power input from the engine to the transmission. The clutch is a common component in mechanical transmission, which can separate or engage the transmission system at any time. The basic requirements for it are: smooth engagement, quick and complete separation; easy adjustment and repair; small overall dimensions; small mass; good wear resistance and sufficient heat dissipation capacity; easy and labor-saving operation. The commonly used ones are divided into two types: tooth type and friction type; The elastic body of the dynamic torque measurement generally participates in relative motion (mainly rotation). Because of the relative motion, the overall design has high requirements for lead / signal processing and mechanical connection methods; When measuring the torque of the clutch, tooling is required to fix the clutch.

[0003] The inventor discovered the following defects during the operation of the specific embodiment: However, the tooling can only fix one clutch at a time.
