Abstract: A clutch engagement booster system is an apparatus used to support and improve clutch engagement on motor vehicles, both as a modification to existing clutch assemblies or as a standalone installation in various embodiments. The clutch engagement booster system utilizes a casing and pressure housing supporting a diaphragm, an expansion chamber, an engagement member, and at least one clutch element. The expansion chamber is formed between the diaphragm and the pressure housing in fluid communication with at least one pressure source through the at least one regulator device. The at least one clutch element is positioned within the casing, opposite the diaphragm across the engagement member. As the expansion chamber is pressurized the diaphragm deforms towards the engagement member, thereby forcing the at least one clutch element into engagement to transfer power through a host transmission.

Abstract: A clutch thrust bearing device includes a rolling bearing having a fixed ring, a rotatable ring, and a plurality of rolling elements between the rings; an axially movable piston disposed between a housing and the rolling bearing and having a radial plate pressing against an axial contact surface of the fixed ring; at least one resilient seal member sealing the piston relative to the housing; and a resilient body exerting an axial preload onto an axial contact surface of the rotatable ring. The rolling bearing is axially movable by the piston to compress the resilient body. A resilient sleeve is mounted to the fixed ring and has at least one sealing lip in sliding contact with the rotatable ring.

Abstract: A clutch thrust bearing device having a ball bearing with a fixed inner ring, a rotatable outer ring, and at least one series of balls located in a raceway chamber disposed between the rings. The device also provides a piston having a substantially radial portion, the fixed inner ring being in axial abutment against the substantially radial portion. The piston further provides an axial portion arranged in a bore of the fixed inner ring of the ball bearing, the axial portion being provided with at least one outwards radial projection that extends between the fixed inner ring and the rotatable outer ring.

Abstract: The invention relates to a vehicle vibration device of a vehicle seat or of a vehicle cab, comprising a lower part and an upper part which can be deflected relative to this lower part, in which device the upper part and the lower part are interconnected in a spring-loaded manner by means of at least one suspension apparatus and in which the suspension apparatus comprises a deformable fluid-spring part having a flexible pressure chamber element and a deformation apparatus having deformation elements, the deformable fluid element being deformed at least in part by the deformation elements when the upper part is deflected relative to the lower part, and wherein, according to the invention, an additional anti-abrasion element is arranged between the flexible pressure chamber element and the deformation elements.

Abstract: A device for uncoupling a drive shaft of a piece of equipment from an input shaft. The device includes a claw including first teeth and first splines to (i) move longitudinally along a first of the shafts by co-operating with second splines borne by the second of the shafts and (ii) engage or disengage the first teeth in relation to the second teeth positioned on the second shaft. The device also includes a longitudinal movement mechanism including a stationary part acting on a longitudinally mobile piece to move the claw between a coupling position and an uncoupling position. The longitudinal movement mechanism drives the claw by co-operation between a rotationally fixed piece and a piece that is linked to the claw and rotated therewith, a longitudinal clearance being maintained during operation between the piece that is rotationally fixed and the rotated piece.

Abstract: A clutch actuator controlled by a pressure medium, in particular for a compressor clutch of a commercial vehicle has an actuating piston displaceably disposed in a housing in an axial direction. An end of the actuating piston is supported in the axial direction on an elastic membrane, sealing a first region of the housing off from a second region of the housing. The elastic membrane includes a raised area on the side opposite the actuating piston. The clutch actuator can be used in a compressor clutch for a commercial vehicle.

Abstract: An integrated wheel end which includes a movable clutch ring for selective engagement between an engaged and disengaged position for transferring driving torque from a drive shaft to the wheel end. The integrated wheel end incorporates a clutch ring abutment feature or travel limiter configured to position the movable clutch ring relative to a coupler on the wheel end during assembly with the drive shaft.

Abstract: A wheel disconnect system is provided including a rear drive module and a constant velocity joint housing. The rear drive module includes a housing, at least one actuator, and at least one dog clutch. The dog clutch includes a first portion configured to move when the actuator is moved and a second portion configured for engagement with the first portion. The constant velocity joint housing is formed integrally with the second portion of the dog clutch. A wheel may be disconnected from the rear drive module unless engagement of the first and second portions of the dog clutch allows torque to be transferred to the wheel. In one embodiment, a hydraulically activated piston may be used to activate the first portion of the dog clutch. In another embodiment, a ball ramp may be used to activate the first portion of the dog clutch. A vehicle driveline including a wheel disconnect system is also provided.

Abstract: A motorcycle clutch for a drive connection between an engine and a transmission of a motorcycle is provided, and is some embodiments includes a manually operable clutch lever, engaging inner and outer disks, and a disengaging mechanism operable by means of the clutch lever for a pressure body which is spring-loaded by at least one clutch spring assembly for pressurization of the inner and outer disks, wherein a servo mechanism for reducing the operating force of the clutch lever is provided, the servo mechanism being effectively connected to the intake section of the engine and utilizing the negative intake pressure in the intake section to build up a servo force acting against the direction of the spring load of the clutch spring assembly.
