A kind of clutch and clutch
Technical field
The present invention relates to clutches, and in particular to a kind of clutch and clutch.
Background technology
Chinese patent discloses a kind of application No. is 201610765079.6 clutch and friction disk type overdrive clutch
Device.Wherein, the clutch includes driving link, and the driven member with the axially opposing setting of the driving link is sheathed on the master
Moving part and/or driven member are to limit the locating part of the relative rotation angle of the driving link and driven member, and are set to described
Rolling element between driving link and driven member.The driving link is provided with multiple first V-types slope on one side towards the driven member
Face, the driven member are provided with multiple the second V-type slopes to match with the first V-type slope surface on one side towards the driving link
Face, the rolling element are set between the multiple first V-type slope surface and multiple second V-type slope surfaces.Although in the clutch
By the design of rolling element reduce to a certain extent when relative rotary motion occurs for driving link and driven member the first V-type slope surface with
