TECHNICAL FIELD
[0001] The utility model belongs to clutch torsion test technical field especially, it relates to a clutch torsion simulation test machine. BACKGROUND
[0002] With the development of society, more and more cars enter people's life and work, and the main transmission mechanism in the car is clutch, mainly used to transmit the power of engine to the transmission wheel. The clutch is located in the flywheel housing between the engine and the gearbox, and the clutch assembly is fixed on the rear plane of the flywheel by screws, and the output shaft of the clutch is the input shaft of the gearbox. During the driving process of the automobile, the driver can step on or release the clutch pedal according to the need, so that the engine and the gearbox are temporarily separated and gradually connected, so as to cut off or transmit the power input from the engine to the transmission. The clutch is a commonly used component in mechanical transmission, which can separate or connect the transmission system at any time. The basic requirements are: smooth connection, rapid and complete separation.
[0003] The clutch is composed of a flywheel, a clutch plate, a pressure plate, a clutch cover and a diaphragm spring. The flywheel is connected with the driving end of the engine, and the engine drives the flywheel to rotate. The clutch plate is connected with the output shaft. The flywheel and the clutch plate are connected through friction force to drive the output shaft to rotate and drive the gearbox to move. The pressure plate is used to press the clutch plate tightly against the flywheel. The clutch cover is used to cover the pressure plate to drive the pressure plate to press the clutch plate. The diaphragm spring is arranged on the clutch cover and connected with the pressure plate. The diaphragm spring is used to drive the pressure plate to move towards or away from the clutch plate, and drive the clutch plate to press or release the flywheel.
[0004] Therefore, during the production process of the clutch, the torsion of the clutch needs to be tested to prevent the clutch from transmitting insufficient torsion, resulting in unstable torsion output by the output shaft to the gearbox, and unstable connection.

The traditional torsion testing machine only detects the torsion of the clutch and the engine in the completely linked state, but during the driving process of the automobile, the gear needs to be changed to match different driving conditions, and the connection between the clutch and the engine needs to be disconnected. Therefore, during the driving process, the working state of the clutch and the engine is completely linked, semi-linked and non-linked, and the traditional torsion detection only for the completely linked state of the clutch and the engine cannot meet the detection requirements.
