Abstract

The invention comprises a clutch unit, comprising a pressure plate (24) by means of which, as a result of axial displacement, a clutch disc (16) which bears friction linings (20) can be pressed against a pressure plate (12) to form a frictionally engaging connection, wherein the axial displacement of the pressure plate (24) can be effected by means of an axial displacement of a lever spring plate (28) which has a circular outer circumference and which bears against one or more protuberances (29) arranged annularly on a surface, which faces toward the lever spring plate (28), of the pressure plate (24) so as to be spaced apart radially from the outer edge thereof, and wherein the pressure plate (24) has, radially at the outside on that side thereof which faces towards the lever spring plate (28), an annular, axially projecting edge (36). The invention is characterized in that at least three radial projections (42) which are spaced apart in the circumferential direction are arranged on the radially inner wall (38) of the axially projecting edge (36), wherein a diameter of a circle which tangentially contacts the radial projections corresponds to the outer diameter of the lever spring plate (28), such that said lever spring plate is held centered on the radial projections (42) and, between in each case two adjacent radial projections (42), the outer edge of said lever spring plate is spaced apart from the radially inner wall (38) of the axially projecting edge (36).

Description

technical field [0001] The invention relates to a clutch, including a pressing plate, by means of the axial movement of the pressing plate, a clutch disc with some friction plates can be pressed against the pressing plate to form a frictional connection, wherein the axial movement of the pressing plate can It is produced by axially displacing a lever spring with a circular outer periphery, which rests on one or more protuberances which are arranged annularly at a radial distance from the outer edge of the pressure plate. On the surface of the distance facing the lever spring leaf, and wherein the pressure plate has an axially protruding annular edge at its radially outer end facing the lever spring leaf. Background technique [0002] Such a clutch is known from DE 10 2008 031 953 A1. [0003] The above patent application documents disclose a clutch, especially a dual clutch used in a dual clutch transmission. Known double clutches comprise two clutch plates, which can be c...
