Abstract
A pressure plate for a friction clutch has a friction-surface region which can be pressed against a friction-lining arrangement of a clutch disk or the like. The pressure plate, in the friction-surface region, is formed at least partially from a first material which provides rapid dissipation of heat generated by friction, and in a body region which adjoins the friction-surface region, is formed from a second material which has a high heat absorption capacity for the heat dissipated from the friction-surface region.

A pressure plate for a friction clutch, comprising:
- a friction-surface region;
- and
- a body region that adjoins the friction-surface region, the pressure plate, in the friction-surface region, being at least partially formed from a first material which provides dissipation of heat generated by friction, and in the body region, the pressure plate is formed from a second material which has a heat absorption capacity for heat dissipated from the friction-surface region, the first material being aluminum and the second material being gray cast iron so that the pressure plate is an aluminum/gray cast iron composite, the first material being in direct contact with the second material.

- a friction-surface region;
- and
- a body region that adjoins the friction-surface region, the pressure plate, in the friction-surface region, being at least partially formed from a first material which provides dissipation of heat generated by friction, and in the body region, the pressure plate is formed from a second material which has a heat absorption capacity for heat dissipated from the friction-surface region, the body region being substantially encapsulated by the first material so that the first and second materials are in direct contact.
