  • Patent number: 6662923
    Abstract: 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.

  • Patent number: 6622840
    Abstract: A double clutch assembly comprising a first clutch area for the optional production of a torque-transmitting connection between a drive element and a first driven element, a second clutch area for the optional production of a torque-transmitting connection between the drive element and a second driven element, and a common engaging/disengaging mechanism, by means of which the first clutch area and the second clutch area can be actuated to produce or to nullify the torque-transmitting condition.

  • Patent number: 6588567
    Abstract: 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).

  • Patent number: 6588566
    Abstract: A pressure plate assembly for a friction clutch includes a housing; a pressure plate held in the housing with freedom to move in the same direction as that in which a rotational axis (A) extends; 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 and/or between the stored-energy element and the housing arrangement, where the wear-compensating device has at least one adjusting element able to move in an adjusting direction to compensate for wear. A clearance-producing arrangement includes at least one gripping element, where the minimum of one gripping element has a body section, one end of which is attached to the assembly consisting of the pressure plate and the housing, between which assembly and the stored-energy element the wear-compensating device acts.

  • Patent number: 6578687
    Abstract: A pressure plate assembly for a friction clutch includes a housing arrangement and a pressure plate arrangement, which is held by at least one leaf spring arrangement with freedom of axial movement relative to the housing arrangement. The at least one leaf spring arrangement is fixed by a first attachment area to a first fastening area of the pressure plate arrangement and by a second attachment area to a second fastening area of the housing arrangement. The end area of the first fastening area and/or the second fastening area curves away from the minimum of one leaf spring arrangement, this end area being located in the area along which the at least one leaf spring arrangement extends.

  • Patent number: 6457572
    Abstract: A first clutch area produces a first torque-transmitting connection between a drive element and a first driven element, and a second clutch area produces a second torque-transmitting connection between the drive element and a second driven element. A common engaging/disengaging mechanism actuates the first clutch area and the second clutch area to produce and to nullify the first and second torque-transmitting connections.
