Background
The friction clutch is a clutch which is widely applied and has the longest history, and basically comprises a driving part, a driven part, a pressing mechanism and an operating mechanism. The driving part, the driven part and the pressing mechanism are basic structures for ensuring that the clutch is in an engaged state and can transmit power, and the operating mechanism of the clutch is mainly a device for separating the clutch. In the process of separation, a clutch pedal is stepped, the free clearance of the clutch is firstly eliminated in the free stroke, then the separation clearance is generated in the working stroke, and the clutch is separated. During engagement, the clutch pedal is gradually released, the pressure plate moves forward under the action of the compression spring, the separation gap is firstly eliminated, and sufficient compression force acts on the pressure plate, the driven plate and the flywheel working surface; the release bearing then moves backwards under the action of the return spring, creating a free gap and the clutch engages. The separation and connection mode has complex structure and inconvenient operation.
