Abstract
A dry friction clutch plate is of the kind having a metallic support plate with ring-shaped friction pads arranged on either side of it. A ring-shaped compression element is arranged between the friction pads, this ring-shaped element being of a cellular material. The cellular material is a deformable material having open and/or closed cavities or pores such as to cause the thickness of the ring-shaped compression element to be reduced when the clutch plate is subjected to compressive stresses, and to cause it to revert to its original thickness on the removal of the compressive stresses.
Claims9
A dry friction clutch plate for applying progressive transmission of engine torque through a motor vehicle drive train through selective application of compressive forces to at least one ring-shaped support plate, the clutch plate comprising two flat ring-shaped friction pads secured on opposite sides of the ring-shaped support plate at periphery thereof, a flat resilient ring-shaped compression element of a porous material inserted between said pads, the porous material being a predetermined porosity and uniformly distributed between said pads, the support plate being disposed between said friction pads, said compression element predetermined porosity imparting sufficient resiliency to said compression element to absorb the selectively applied motor vehicle drive train compressive forces for the progressive transmission of the engine torque therethrough.
