    • A pressure plate (22, 26, 34) for a friction clutch (20) is provided, having a plate body, wherein the plate body has at least one friction surface for frictionally transmitting a torque to a clutch disc (32), wherein the plate body has been surface treated at least in the region of the friction surface by blasting, in particular sandblasting and/or shot peening. As a result of the friction surface of the plate body of the pressure plate (22, 26, 34) being blasted, an initial roughness that is favourable for a running-in process, and wear-resistant compression of the plate body can be achieved, with the result that, with low tolerance specifications for the components of a friction clutch (20), a high service life can be achieved, such that a cost-effective friction clutch (20) having a long service life is enabled.
    • 提供用于摩擦离合器(20)的压力板(22,26,34),其具有板体,其中板体具有至少一个摩擦表面,用于摩擦地将扭矩传递到离合器盘(32),其中, 至少在摩擦表面的区域内通过喷砂,特别是喷砂和/或喷丸硬化对板体进行表面处理。 由于压力板(22,26,34)的板体的摩擦表面被喷砂,可以实现有利于磨合过程的初始粗糙度和板体的耐磨压缩 结果是,对于摩擦离合器20的部件具有低公差规格,可以实现高使用寿命,从而能够实现具有长使用寿命的低成本摩擦离合器20。
