Abstract
A pressure plate assembly for a multi-disk clutch includes a housing arrangement, a pressure plate mounted in the housing arrangement with freedom to move in the same direction as an axis of rotation but connected to the housing with essentially no freedom of rotation and an intermediate plate mounted in the housing arrangement with freedom to move in the same direction as the axis of rotation but connected to the housing with essentially no freedom of rotation. A release distance preset arrangement for the intermediate plate includes at least one sensing element on the intermediate plate which rests on an assembly which shifts position during the performance of a releasing movement of the pressure plate. The at least one sensing element allows the intermediate plate to execute a releasing movement corresponding to the shift of this assembly. The at least one sensing element contacting the assembly is pretensioned by an intermediate plate release force-generating arrangement acting on the intermediate plate. At least one rotational coupling projection is arranged on either the intermediate plate or the housing arrangement which fits in a rotational coupling recess the other of the intermediate plate or the housing arrangement to produce a rotational coupling between the intermediate plate and the housing arrangement.
