The invention further provides an engine comprising the clutch, which can solve the problem of abnormal sound generated by the slip of the friction plate when the clutch starts at a high rotating speed and simultaneously reduce the abrasion of the clutch.
Referring to fig. 2 to 14, in an embodiment of the clutch provided by the present invention, the clutch includes a first friction plate assembly and a second friction plate assembly installed between a center housing body and a pressing plate.
The first friction plate assembly includes a plurality of first friction plates 5 sequentially arranged in the axial direction, and specifically one or at least two may be arranged. Each of the first friction plates 5 moves synchronously in the circumferential direction. That is, the movement states of the first friction plates 5 in the circumferential direction are uniform, and the rotation is stopped or rotated at the same speed.
The second friction plate assembly includes a plurality of second friction plates 6 sequentially arranged in the axial direction, and specifically one or at least two may be provided. Each second friction plate 6 moves synchronously in the circumferential direction. That is, the movement state of the second friction plate 6 is uniform in the circumferential direction, and the rotation is either stopped or rotated at the same speed.
The first friction plates 5 and the second friction plates 6 are arranged in an axial staggered manner. The first friction plate 5 and the adjacent second friction plate 6 are combined through axial relative movement so that the first friction plate assembly and the second friction plate assembly can synchronously move in the circumferential direction by friction force, or the first friction plate 5 and the adjacent second friction plate 6 are separated through axial relative movement so that the first friction plate assembly and the second friction plate assembly respectively and independently move in the circumferential direction.

The second connecting pin 74 fixes the wave spring 72 to the left side split friction plate 71.
Based on the setting of dodging hole 75, when two branch friction discs 71 combine together, the connecting pin of fixed setting on one of them branch friction disc 71 protrusion in the portion of dodging hole 75 that corresponds on another branch friction disc 71 for two branch friction discs 71 can laminate together, and two branch friction discs 71 can not be propped apart by the connecting pin, can avoid branch friction disc 71 to be supported the damage by the connecting pin.
Further, after the two sub friction plates 71 are combined, the two sub friction plates 71 can be attached, and at the same time, the connecting pin does not protrude from the two axial end faces of the two sub friction plates 71 away from each other in the axial direction, the axial direction corresponds to the left-right direction in the direction of fig. 9, and the connecting pin does not protrude from the left end face of the left sub friction plate 71 and the right end face of the right sub friction plate 71, so that the connecting pin can be prevented from damaging the adjacent first friction plate 5 in the attached state of the connecting pin.
