Qingzhou Jinma tricycle clutch and throttle can't be stepped on. What happened?

Hello, dear, there are three reasons why the clutch can't be stepped on: 1, the clutch cable is stuck; 2. The release bearing is damaged; 3. There is something wrong with the clutch master cylinder and the slave cylinder. The clutch is located in the flywheel housing between the engine and the gearbox. The clutch assembly is fixed on the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the gearbox. When the car is running, the driver can step on or release the clutch pedal as needed, so that the engine and gearbox are temporarily separated and gradually engaged, thus cutting off or transmitting the power input from the engine to the gearbox. Clutch is a common component in mechanical transmission, which can be separated or engaged at any time. Its basic requirements are: smooth joint, rapid and complete separation; Convenient adjustment and maintenance; Small overall size; Small mass; Good wear resistance and sufficient heat dissipation capacity; The operation is convenient and labor-saving, and the common ones are claw type and friction type.
