Plate clutch for motor vehicles, especially motorcycles

A plate clutch for motor vehicles, comprising:

• a primary gear configured to be coupled to a flywheel of an internal combustion engine;
• a clutch shaft, upon which the primary gear is rotatably mounted;
• a clutch cage rigidly connected to the primary gear;
• a driver arranged concentrically on, and rigidly connected to, the clutch shaft;
• a pressure plate, the pressure plate being coupled to the driver so as to permit axial movement of the pressure plate relative to the driver;
• a pressure pad rigidly connected to the pressure plate;
• a Belleville spring, the Belleville spring being supported on the driver at an outer peripheral area of the Belleville spring and on the pressure pad at an inner peripheral area of the Belleville spring;
• a stack of annular clutch plates, alternate plates of said stack being coupled with the cage or the driver in a manner which permits axial movement of the plates in response to application and release of pressure applied between the pressure plate and the driver;
• a throwout bearing arranged coaxially to the clutch shaft to apply an axial release force via the pressure pad to the pressure plate;
• and
• a pressure mushroom with an annular flange and extension which receives a clutch actuation force, wherein the annular flange rests against an internal ring of the throwout bearing, and the extension is guided in an axial hole of the clutch shaft so as to permit coaxial axial movement of the extension within the axial hole upon application of the clutch actuation force on the pressure mushroom.
