The principle and beneficial effect of this basic scheme lie in: when the pressing plate and the clutch center sleeve are combined with the driving friction plate and the driven friction plate under the action of the spring, the driving friction plate drives the driven friction plate to rotate through friction force, the driven friction plate drives the clutch center sleeve to rotate, the clutch center sleeve drives the center sleeve pressing plate to rotate through the second combining part and the first combining part, the second combining part and the first combining part realize relative rotation through the movable cavity in the process of driving the first combining part to extrude an elastic piece in the movable cavity, and the elastic piece buffers impact force generated when the first combining part and the second combining part are combined, so that the impact phenomenon generated when the clutch is combined in the moment is effectively reduced.
Further, the central sleeve pressing plate comprises a connecting cylinder part protruding along the axial direction, and the first combination part is a protruding part extending along the radial direction; the second combining part is a sliding groove which is arranged on the clutch center sleeve and extends along the radial direction. By adopting the arrangement, the processing arrangement of the first combining part and the second combining part is convenient.
Further, the spring is a disc spring. The elastic force exerted by the disc springs is uniform, so that the stress between the driving friction plate and the driven friction plate is uniform, the combination and the separation can be smoothly carried out, and the phenomenon of incomplete separation is reduced.
Further, the disc spring is located on one side of the pressing plate away from the clutch center sleeve. By adopting the arrangement, the disc spring is convenient to install.
Further, one side of the disc spring, which is far away from the pressing plate, is provided with a limiting plate, and the limiting plate is connected with the clutch center sleeve through a bolt.
Further, the elastic piece comprises two elastic blocks which are arranged side by side, and the two elastic blocks are symmetrically arranged on two sides of the protruding portion. By adopting the arrangement, the first combining part and the second combining part can be isolated and buffered by the elastic block, so that noise generated in the using process of the clutch is reduced.
