The plurality of first connection holes 110 and the plurality of second connection holes 111 are alternately arranged in order in the circumferential direction of the annular plate 11 b. The positions and the number of the positioning notches 112 are provided in one-to-one correspondence with the positions and the number of the second connection holes 111. When the wave-shaped sheet 13 includes a plurality of connecting portions 132, the positioning notch 112 is disposed between two adjacent connecting portions 132.

Optionally, annular plate 11b includes an annular base 118 and a plurality of posts 116 extending axially therefrom on one end face of annular base 118. The plurality of bosses 116 are provided at intervals in the circumferential direction of the annular plate 11 b. When the wave-shaped sheet 13 has more than two connecting portions 132, each stud 116 can fill a gap between adjacent two connecting portions 132. Thus, on the one hand, each connection 132 is adapted to limit the entire annular plate 11b by being fitted with each stud 116. When the annular plate 11b receives an acting force in the circumferential direction of the driven disc main body 10, since it is restricted by the restriction of the connecting portion 132, the position of itself is not substantially changed, positional stability is ensured, and the entire structure is not easily deformed to cause a change in the distance between the connecting portion 132 and the driven disc main body 10. On the other hand, after the annular plate 11b is assembled with the driven disc main body 10, when the corrugated sheet 13 is installed, the two adjacent convex columns 116 position the connecting portion 132, so that the connecting portion 132 can be quickly and accurately installed at a predetermined position, and the assembly efficiency of the driven disc 1 is improved.

In one embodiment, two or more annular plates 11b are provided between the connecting portion 132 and the driven disk main body 10. Two or more annular plates 11b are stacked in the axial direction of the driven disk main body 10. The two or more annular plates 11b have the same structure, and may have the same thickness or different thicknesses. In this way, only a series of thicknesses or a single thickness of the annular plate 11b needs to be processed, and thus, according to actual needs, two or more annular plates 11b can be selected from the series of thicknesses of the annular plates 11b or two or more annular plates 11b with the same thickness can be arranged between the connecting portion 132 and the driven disk main body 10, so that the distance between the connecting portion 132 and the driven disk main body 10 can be flexibly adjusted.

The embodiment of the invention also relates to a clutch for the vehicle. The clutch includes a gland 3 and the driven plate 1 of the above embodiment. When the clutch of the embodiment is matched with the flywheel 2 on the engine for use, the clutch of the driven plate 1 and the flywheel 2 is controlled through the gland 3. The driven disk 1 includes a driven disk main body 10. The distance between the end face of the driven disc main body 10 facing the flywheel 2 and the end face of the flywheel 2 facing the driven disc main body 10, or the distance between the end face of the driven disc main body 10 facing the gland 3 and the end face of the gland 3 facing the driven disc main body 10 can be flexibly adjusted according to actual requirements, so that the minimum distance between the end face of the driven disc main body 10 facing the flywheel 2 and the end face of the flywheel 2 facing the driven disc main body 10, the minimum distance between the end face of the driven disc main body 10 facing the flywheel 2 and the bolt of the flywheel 2 facing the driven disc main body 10, or the minimum distance between the end face of the driven disc main body 10 facing the gland 3 and the end face of the gland 3 facing the driven disc main body 10 is smaller than a critical value, and the safety of the clutch in the use process is guaranteed.
