Construction and operation of a single-disc friction clutch.
The single disc clutch is the most common type of clutch. The principle of its operation is as follows: A flywheel is attached to the end of the crankshaft, to which the clutch cover is screwed with screws. The splined clutch shaft is mounted on one end in the engine crankshaft, and the other in the gearbox. A clutch disc with friction lining on both sides is slid over the spline part of the shaft to increase friction. The clutch disc has a translational movement along a shaft, and the rotation with it. The pressure on the clutch disc is exerted by the disc (ring) The pressure plate rotates with the clutch cover, and pushed away from it by several springs placed in sockets on the cover housing. Clutch disc, constantly compressed between the flywheel and the pressure plate, it transmits a frictional rotational motion from the flywheel to the clutch shaft, then to the gearbox and further powertrains of the car. The clutch is disengaged by pressing the pedal, which, with the help of a fork and a thrust bearing, pulls back the pressure plate, thereby releasing the clutch plate.
Wanting to engage the clutch, you need to take your foot off the pedal. When the pedal is released, the pressure springs in the clutch cover expand, press on the pressure plate and push it into the flywheel, and this in turn presses the clutch plate against the flywheel. Need caution, to slowly take your foot off the clutch pedal when starting the car, which will allow the slow and gradual pressing of the stationary clutch plate against the spinning flywheel, and thus a smooth start.
