Embodiment Construction

[0036] exist figure 1The pressure plate assembly 1 designed according to the invention shown in , is provided with a housing part 3 which is connected to a mating housing part 5 . A pressure plate 6 with one of the two counter-friction surfaces 4 is inserted in the housing part 3 in a rotationally fixed manner relative to the housing part 3 , but axially displaceable. Furthermore, a force accumulator 9 in the form of a diaphragm spring is arranged on the housing part 3 for applying a pressing force to the pressure plate 6 . However, it is also possible to provide the force store 9 as a lever element which transmits the pressing force generated outside the pressure plate assembly 1 to the force store 9 via the clutch actuation system. Such an embodiment is generally referred to in the prior art as a "normally-open-clutch'", ie a clutch of the normally open type. A wear readjustment device 10 is formed on the pressure plate 6 and has at least one readjustment element 11 for co...

Abstract

The invention relates to a pressure plate assembly (1), particularly for a friction clutch, having automatic wear compensation, comprising a housing part connected to an opposite housing part (5) having an opposite friction surface (4), such as a flywheel, a dual-weighted flywheel, or an input part having an effective connection to the crankshaft of an engine, a pressure plate (6) disposed in thehousing part (3) and mounted movably in the direction of the rotary axis toward the pressure plate assembly, comprising a further opposite friction surface for engaging the opposite friction surface with friction surfaces formed on a clutch disc, a force storage (9) by means of which a press force is applied to the pressure plate, a wear adjustment device (10)acting in the force transfer path between the force storage and the pressure plate, wherein the wear adjustment device comprises at least one adjusting element (11) movable in an adjusting direction for adjusting wear, at least one play indicating arrangement (12) comprising a detecting element (13) provided on the pressure plate that contacts or can be brought into contact with a blocking element (14) supported by fixing relative tothe housing part or the opposite housing part when wear occurs, wherein an adjusting element (15) fixedly supported relative to the housing part is provided, by means of which the contact of the detecting element to the blocking element can be modified by impinging on the blocking element.

Description

technical field [0001] The invention relates to a pressure plate assembly (Druckplattenbaugruppe) with automatic wear compensation, in particular for a friction clutch (Reibungskupplung), comprising: a housing part with a mating friction surface Mating case parts for (such as a flywheel, a dual-mass flywheel or an input part that is operatively connected to the crankshaft of the engine); is arranged in the housing part and is held in a movable manner relative to the pressure plate assembly in the direction of the axis of rotation, with another Pressure plate (Anpressplatte) of the mating friction surface, which is used for the interaction of the mating friction surface and the clutch plate (Kupplungsscheibe) with the corresponding friction surface; force accumulator (Kraftspeicher), via which the compression plate is pressed Applying a pressing force (Anpresskraft); a wear readjustment device (Verschleiβnachstellvorrichtung) acting in the force transmission path between the...
