US 2003/0164274 A1 · Multi-clutch arrangement

Abstract

Multi-clutch arrangement, comprising at least two clutch areas, each with a pressure plate, which can be connected to a housing for rotation in common around an axis of rotation (A) and which can be shifted in the axial direction relative to this housing; with an opposing support; and with a clutch disk, the friction surface arrangement of which can be clamped between the pressure plate and the opposing support. Each of the clutch disks is designed to be connected nonrotatably to a different power takeoff element. A wear-compensating device is assigned to at least one of the clutch areas. In at least one of the clutch areas, the pressure plate is connected to the housing for rotation in common by way of a connecting element arrangement, which, when the clutch area is in the torque-transmitting state, exerts a force on the pressure plate arrangement acting in the direction toward the opposing support.

Dependent claims

A multi-clutch arrangement comprising

a housing,
a pair of pressure plates connected to said housing for rotation in common about an axis of rotation and which can be shifted axially with respect to said housing,
an opposing support arranged between said pressure plates, and
a pair of clutch disks having friction surfaces which can clamped between said opposing support and respective said pressure plates, each said clutch disk being connectable nonrotatably to a respective power takeoff element, wherein
at least one of said pressure plates and said opposing support comprises a first material which comes into contact with said friction material and a second material which is axially farther from said friction material than said first material, said first material having a coefficient of thermal expansion which is lower than the coefficient of thermal expansion of said second material.
