Clutch disc

The invention belongs to the technical field of clutches, and particularly relates to a clutch disc. The clutch disc comprises a disc-shaped disc body; a mounting seat is arranged in the middle of thedisc body, a group of arc-shaped grooves are uniformly distributed in the periphery of the disc body on the periphery of the mounting seat, and damping springs are mounted in the arc-shaped grooves through a pair of bosses; annular air bags are arranged between the damping spring and the disc body, and the air bags sleeve on the bosses; and a set of friction plates are evenly distributed on the circumference of the portion, close to the outer edge, of the plate body, and vent holes are formed in the friction plates and communicate with the air bags through pipelines. According to the clutch disc, vibration of the disc body is absorbed through shaking of the damping spring, so that the disc body stably rotates, the service life of the disc body is prolonged, meanwhile, the damping springscontinuously extrude the a
