Description

Technical Field

[0001] The invention relates to the technical field of detection equipment, and in particular to a clutch assembly performance detection device. Background Art

[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 process of the car, the driver can step on or release the clutch pedal as needed to temporarily separate and gradually engage the engine and the 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 outer dimensions; small mass; good wear resistance and sufficient heat dissipation capacity; easy and labor-saving operation. The commonly used types are divided into two categories: tooth type and friction type.

[0003] At present, when testing the performance of the clutch assembly, it is necessary to test the performance of the friction brake pad in the clutch assembly. The existing Chinese patent with the announcement number of CN116106148A discloses a clutch friction performance testing device, including a base and a friction pad, a motor is fixedly connected to the bottom of the middle part of the base, a first gear is fixedly connected to the top of the motor, a second gear is meshed on one side of the first gear, a rotating rod is fixedly connected to the middle part of the second gear, and friction blocks are movably connected to the left and right sides of the top of the friction pad. The present invention achieves good detection effect of the device through the coordination of the motor, the first gear, the second gear, the rotating rod, the friction pad and the friction block, the movable rod moves downward along the fixed cylinder, the movable rod drives the connecting block, and the fixed block drives the friction block to move downward, by starting the motor, the second gear drives the rotating rod to rotate clockwise, and the rotating rod drives the friction pad to rotate clockwise, and the device achieves good detection effect through the coordination of the motor, the first gear, the second gear, the rotating rod, the friction pad and the friction block.

[0004] Although the technical solution proposed by the above patent technology can test the performance of the friction plate, in the actual test process, it needs to rely on the rotation of the friction plate to make it contact with the friction block for testing. In the actual braking process of the car, the friction plate in the clutch assembly needs to be in contact with the high-speed rotating brake disc, that is, when the clutch assembly is braking, the friction plate can only translate but not rotate. As a result, the above technical solution cannot replicate the actual operating trajectory of the car clutch assembly, resulting in certain errors in the detection data. Moreover, the technical solution proposed by the above patent technology cannot effectively fix friction plates of different sizes, and the friction plate is prone to slip during the experiment, and the stability is poor.
