  • Publication number: 20070235280
    Abstract: A clutch-release device for a friction clutch installed in a housing in a vehicle includes a guide tube and a clutch-release bearing, which is free to shift position in the axial direction on the tube by means of a bearing carrier. One bearing ring of the clutch-release bearing is connected to the clutch-release element of the friction clutch to transmit the actuating force for actuating the friction clutch. The other bearing ring is mounted nonrotatably on the bearing carrier. For lubrication, the clutch-release bearing is provided with a relubrication unit provided with a freely controllable actuation unit for the as-needed lubrication of the clutch-release bearing.

  • Publication number: 20070205074
    Abstract: A clutch release device for the friction clutch of a motor vehicle includes a sliding sleeve which can shift position axially on a guide tube, and a roller bearing positioned on the sliding sleeve. The roller bearing includes a first bearing ring, which can rotate with a clutch release element, a second bearing ring, which is fixed against rotation relative to the sliding sleeve, and a plurality of rolling elements which roll on races in the bearing rings. In the event of bearing failure, first and second axial stops engage to prevent relative axial displacement of the bearing rings by more than a predetermined amount. The first axial stop is fixed with respect to the first bearing ring, and the second axial stop is axially fixed with respect to the sliding sleeve.

  • Publication number: 20070205073
    Abstract: A clutch-release device for a friction clutch of a motor vehicle includes a guide tube and a sliding sleeve, which is free to shift position axially on the tube, the sleeve having a contact area for absorbing the actuating force of an actuating element. A clutch-release bearing is mounted on the sliding sleeve, the bearing having a nonrotatable first bearing ring, rolling elements, and a rotating second bearing ring, which is in working connection with an actuating element of the friction clutch. To increase the number of identical parts and thus to reduce costs, the sliding sleeve has a multi-part design, thus representing an assembly having at least two parts.

  • Patent number: 7264103
    Abstract: A release device for a friction clutch includes a guide tube, a sliding sleeve mounted on the guide tube, and a release bearing mounted coaxially to the sliding sleeve, the bearing including a first bearing race, rolling elements, and a rotating second bearing race. The second bearing race supports a connecting element, which establishes the working connection between the release bearing and the ends of spring tongues of a diaphragm spring, which serves as the actuating element of the friction clutch. The connecting element has a receiving section, which holds the ends of the diaphragm spring tongues and can shift position in the radial direction in opposition to a restoring force, and a retaining section for the second bearing race. Radial is placement of the ends of the diaphragm spring tongues which occurs upon axial actuation of the releasing device can be absorbed by the connecting element with essentially no friction.

  • Patent number: 7213696
    Abstract: A friction clutch arrangement includes a clutch housing mounted to a flywheel, a pressure plate, a clutch disk mounted on a transmission shaft, and a diaphragm spring which loads the pressure plate toward the flywheel to engage the clutch. A disengagement device includes a sliding sleeve which is axially displaceable on the shaft to introduce a disengagement force to the clutch spring via an force action point, thereby producing a characteristic curve of disengagement force versus disengagement travel of the sleeve. During disengagement, a compensation device introduces a compensation force counter to the pressing force in a predefined section of the characteristic curve, thereby reducing the disengagement force in the predefined section. A switchable force transmission device changes the effective force transmission ratio of the pressing force and the disengagement force during disengagement in a predetermined manner, thereby optimizing the disengagement stroke of the pressure plate.

  • Patent number: 7117986
    Abstract: The invention concerns a clutch release bearing comprising an axially mobile piston (14), and a ring (26I), integral with a raceway (C1), hooked on the piston (14) with axial-effect squeezing elastic means (38, 40). The ring (26I) is provided with a proximal surface (F1, 62) and a distal surface (F2, 70) arranged axially behind the proximal surface (F1, 62). The proximal surface (F1, 62) is supported on a first hooking surface (A1, 64) provided in the piston (14). The squeezing means (38, 40) are supported on the distal surface (F2, 70) of the ring (26I) and a second hooking surface (A2, 76) provided in the piston (14). The first (A1, 64) and second (A2, 76) hooking surfaces provided in the piston (14) are arranged axially in front of the distal surface (F2, 70) of the ring (26I) The invention also concerns a method for assembling the elements of said clutch release bearing.

  • Patent number: 7021444
    Abstract: A friction clutch intended for a drive assembly of a motor vehicle, operates between an internal-combustion engine and a transmission. The clutch has a clutch release device arranged inside a transmission/clutch housing and has a clutch release bearing and a hydraulic operating device with a cylinder housing and an operating piston operating in the cylinder housing. For optimizing the clutch release device of the friction clutch, the cylinder housing of the hydraulic operating device of the clutch release device is mounted on a bearing structure arranged adjacent to the internal-combustion engine and the friction clutch, which bearing structure is constructed independently of the clutch housing.
