The invention concerns a clutch mechanism comprising a wear take-up mechanism cassette whereof the U-shaped support ( ) is characterized in that at least one of the support ( ) side wings ( ) carries a bearing ( ) centrally bored ( ) receiving one end ( ) of the shaft ( ) of the adjusting rotating element ( ) and which is located in a blind hole ( ) in the wing wherein it is threaded and then locked, particularly by crimping ( ).

Clutch mechanism equipped with a wear take-up module

The invention concerns a clutch mechanism comprising a wear take-up device with a ramp ( ) ring ( ) coupled in rotation into axial mobility with an intermediate part ( ) equipped with a tooting ( ) engaged in an endless screw ( ) integral with a cover. The invention is applicable to a motor vehicle.

Clutch mechanism provided with an endless screw wear take-up device

The friction clutch comprises a reaction plate designed to be blocked on a driving shaft, a friction disk, bearing at its external periphery friction linings, a pressure plate, a cover (,) fixed on the reaction plate, an axially operating clutching device (,) controlled by a disengaging device and which operate between the cover (,) and the pressure plate through a support device, the pressure plate being integral in rotation with the cover (,) and being subjected to the action of an elastic return device (,) axially returning the pressure plate towards the cover (,). The clutch also comprises a wear take-up device comprising a toothed gear (,) with which a worm screw (,) co-operates and a device (,) for resetting in the position corresponding to linings in new condition, the device (,) being placed at the worm screw (,) tip to drive the latter in rotation.

Friction clutch with wear take-up device provided with resetting means and tool adapted to reset said device

The invention concerns a wear take-up mechanism comprising a housing (,) borne by the cover (,) and ramp means (,) set between the means (,) supporting the clutch shifting means and a pressure plate (,). The cassette has two side wings (,) each provided with a hole (,), said holes (,) being axially offset mutually for mounting a rotating endless screw (,) capable of driving in rotation the ramp means (,) and extended by a pin (,). The invention is applicable to motor vehicles.

Friction clutch mechanism, in particular for motor vehicle, comprising a wear take-up device

The invention concerns a clutch mechanism comprising a cover (52) including a housing (218) receiving support (62) shaped like an upside down U of the adjustment cassette containing an upper web (64) fixed to a peripheral edge (152) of the cover (52) by riveted plate bracket (68). The invention is characterised in that the support comprises a stabilising bracket (171) vertically supported against an upper edge (158) pertaining to an aperture formed in a vertical transverse wall of the housing (218).

Clutch mechanism comprising a wear take-up module

A friction clutch for a motor vehicle having a clutching friction member and clutching mechanism with a cover and a clutch thrust plate. A resilient clutch member and disengaging gear is disposed between the rear surface of the thrust plate and the cover for moving the clutch thrust plate towards the cover. The clutch is provided with a wear adjustment device, a resilient servo member and a resilient smooth engagement member. The resilient servo member is mounted outside the clutching friction member. The load pressure feature combining the load pressure features of the resilient servo member and smooth engagement member globally follows the load pressure feature of an axially operating resilient clutching member.

Friction clutch with low disengaging force

The friction clutch comprises a friction disc, a pressure plate (,), a cover plate (,), a diaphragm (,) working between, firstly, the cover plate (,) and secondly the pressure plate (,), the said clutch also including a wear compensating device comprising ramps (,) disposed circumferentially and adapted so as to be driven in rotation by means of a set of teeth (,) which they carry at their periphery and with which a tangentially disposed worm (,) cooperates, a ratchet wheel (,) for driving the worm (,) in rotation being provided and rendered operational by wear in the friction liners when the clutch is engaged, together with non-return catches (,) for preventing the worm (,) from turning in the direction opposite to that in which it is driven in rotation by the ratchet wheel when it is operational, the worm (,), the non-return catches (,) and the ratchet wheel (,) being carried by a support (,) fixed to the cover plate (,): the ratchet wheel (,) of the worm (,) is controlled by the diaphragm (,).

A device for taking up clearance designed to equip a diaphragm friction clutch, having circumferentially distributed ramps designed to cooperate with the thrust plate of the clutch, support areas designed to receive the axial force of the diaphragm of the clutch and a toothing designed to drive them in rotation: the device consists of a ring having on one of its faces ramps alternating circumferentially with support areas constituting the support area.

A torsion damper, especially for a motor vehicle friction clutch, includes a friction unit, or unitary friction assembly, that comprises a guide ring, at least one drive ring, and axially acting resilient members in biassing relationship on the drive ring. The drive ring and these resilient members are mounted in a cavity which is bounded by the guide ring and by a closure ring which is secured to the guide ring. The closure ring is formed at its inner periphery with at least two axial stop lugs for preventing rotation. The stop lug penetrates into an associated aperture which is formed in the guide ring.

Friction unit and a method of making it, and a torsion damper including

The friction clutch includes a device for taking up clearance comprising a ramp device disposed circumferentially and adapted to be rotated by a toothing which they carry at their periphery and with which cooperates a worm disposed tangentially: the worm is mounted so as to slide along its axis while being subject to the action of a so-called taking-up elastic spring and it is when it is moved along its axis that it rotates ramps; the load of the taking-up spring increasing with the wear on the linings the axial movement is obtained when the load is sufficiently high to overcome the axial force due to the return device to which the ramps are subject, with the clutch released; driving of the worm in rotation is provided and made operational by the wear on the friction linings when the clutch is engaged; non-return devices prevent the worm from turning in the direction opposite that in which it is driven by the driving devices.
