摘要:
This invention relates to a friction clutch with a membrane spring in a pulled or pushed clutch, in which there is a second membrane spring/plate spring which assists the release force, and which, when the friction clutch is engaged, exerts little or no release force, and generates a release force which increases with increasing release travel.

A pressure plate assembly for a friction clutch includes a housing for mounting to a flywheel; a pressure plate, held in the housing with the freedom to move in the same direction as that of a rotational axis (A); a stored-energy element; and a wear-compensating device acting in the path of force transmission between the stored-energy element and the pressure plate, where the wear-compensating device has at least one adjusting element, which can move in an adjusting direction to compensate for wear. A clearance-producing arrangement includes a gripping element provided on the pressure plate, which element comes or can be brought to rest against a blocking element (fixed in position relative to the housing arrangement upon the occurrence of wear. When the housing arrangement is being attached to the flywheel arrangement, the blocking element arrives in state in which it is able to enter into a blocking interaction with the associated gripping element.

摘要:
A motor vehicle friction clutch with an automatic adjustment for wear of the friction linings, whereby distributed over the circumference of the pressure plate there are several clearance sensors which act on the thrust plate with the interposition of an adjustment device. Each clearance sensor is thereby mounted in a hole in the thrust plate, so that it can move axially against the force of an adapter sleeve.
摘要:
A pressure plate subassembly for a motor vehicle friction clutch, which subassembly comprises an application plate or pressure plate which, when assembled in a motor vehicle friction clutch, is connected to a flywheel to rotate jointly around an axis and can be axially displaced with respect to the flywheel. The pressure plate has a friction surface which faces the flywheel, and at least one clearance sensor is provided on the pressure plate. The clearance sensor has an operation lever segment that cooperates with a wear adjustment device, and an axial stop segment which cooperates with the flywheel. The pressure plate subassembly comprises the displacement contrivances, which displacement contrivances prevent a displacement of the clearance sensor, of which there is at least one, with respect to the pressure plate prior to the assembly of the pressure plate subassembly to the flywheel. The clearance sensor, of which there is at least one, can be displaced in the axial direction with respect to the pressure plate and is held on the pressure plate in the axial direction by spring pre-stressing.
摘要:
A friction clutch with a mechanism to automatically adjust for the wear of the friction linings by an adjustable-width device. The adjustable-width device includes at least one adjustment element. The adjustment element is centered with respect to the axis of rotation opposite the pressure plate by several guide pins distributed about the circumference of the pressure plate. The guide pins extend axially and support the width of the adjustable element.

A system for engaging or disengaging a friction clutch has at least one drive, which drive is connected to an energy accumulator and is intended to move against the force of a spring mechanism of a friction clutch. The system can have at least one adjusting mechanism for the drive to compensate for the axial shift resulting from the change in position of the spring mechanism due to wear on the friction clutch. This adjusting mechanism can include an actuating mechanism connected to the transfer element. The actuating mechanism can be moved in the direction of motion of the drive, and can include a retaining mechanism which restricts the extension of the actuating mechanism by means of a stop. The retaining mechanism, by means of a retaining force, secures the orientation of the stroke of the actuating mechanism against an axial displacement until an axial shift occurs due to wear of the friction clutch. When there is wear to the friction clutch, a reduction in the force of the spring mechanism can result, which force acts against the actuation force applied by the energy accumulator, since the force of the spring mechanism is reduced, a resulting axial force arises which exceeds the magnitude of the retaining force and an adjustment for the wear can thus be made.
摘要:
A pressure plate arrangement (1) for a friction clutch of a motor vehicle is proposed, wherein an adjustment device (19), which automatically compensates for the wear of the friction linings (21), is disposed in the support path between a diaphragm spring (13) and a pressure plate (11), stressed against a flywheel (1) by the diaphragm spring (13) via friction linings (21) of a clutch disk (23). The adjustment device (19) has a pressure path compensating member (31), for example in the form of a radially resilient cone-shaped ring, which automatically compensates for possible play between the diaphragm spring (13) and the pressure plate (11). Distributed in the circumferential direction, a plurality of play transfer devices (37) is axially movably guided and arrested (for example by self-locking). The play transfer devices (37) rest against the flywheel (1) of the clutch housing (9) fixedly connected therewith and have levers (43) which limit the maximal wear compensation path of the compensating member (31). In this manner a wear compensation, which is independent of possible wear compensation mechanism of a hydraulic clutch disengagement system, takes place within the clutch. In addition, the diaphragm spring (13) of the proposed pressure plate arrangement retains its original position in relation to the flywheel (1) or the clutch housing (9), regardless of a possible wear compensation.
摘要:
In a pulled-type clutch arrangement, for the release of the clutch, release levers are provided which are connected in their radially outer region with the clutch cover and in a radially middle region articulatedly with the thrust plate. On the abutment face facing the drive plate, in the region of the radially inner ends, the release levers lie against a release ring which is connectable with a traction force transmission part of a clutch release device. In some cases the clutch arrangement avoids the diaphragm springs usually used in pulled-type clutch arrangements, and nonetheless can be operated as pulled-type clutch. The main spring can be formed by a dished spring which is simpler in construction than a diaphragm spring and avoids disadvantages which arise with diaphragm springs for some purposes, especially in heavy-duty clutches. The dished springs can here be supported in a radially outer region on the clutch cover and can act in a radially inner region upon the thrust plate.
摘要:
A pressure plate assembly for a friction clutch includes a housing, a pressure plate held in the housing arrangement with freedom to move axially, and a stored-energy element transmitting force along a path between the housing and the pressure plate. A wear-compensating device acting in the path of force transmission has at least one adjusting element able to move in an adjusting direction to compensate for wear. At least one spring element pretensions the minimum of one adjusting element for movement in the adjusting direction, where at least certain areas of the minimum of one spring element extend in the circumferential direction relative to the rotational axis (A). A support arrangement supports the area of the spring element extending essentially in the circumferential direction radially from the outside and/or radially from the inside relative to the rotational axis (A).
