    Hydraulic clutches can be divided into claw type and friction type according to the working principle of engagement element transmission.

    The jaw clutch uses the teeth on the end faces of the two halves of the clutch to engage or disengage each other to achieve the clutch of the main and driven shafts. The advantages are that the transmission torque is large, the size is small, the structure is simple, and there is no slippage during operation, which can ensure the synchronous rotation of the main and driven parts without friction loss.

    The friction clutch utilizes the friction force between the engaging elements to achieve the purpose of transmission. The advantage is that the clutching and closing are stable, soft, and without impact, and the clutching and closing can be carried out under high-speed difference.

    The clutch release bearing is installed between the transmissions in the clutch, and the release bearing seat is loosely sleeved on the tubular extension of the first shaft bearing cover of the transmission. The return spring makes the shoulder of the release bearing always abut the release fork and retreat to the end position, and maintains a gap of about 2.5mm with the separation lever. Since the clutch pressure plate, the release lever, and the engine crankshaft run synchronously, and the release fork can only move axially along the output shaft of the clutch, it is obviously impossible to directly use the release fork to dial the release lever. The axial movement of the output shaft ensures that the clutch can be smoothly engaged and disengaged softly, which reduces wear and prolongs the service life of the clutch and the entire drive train.
