Pull type clutch

Damper disk having axially opposed diaphram sprines

A release bearing mechanism of a clutch comprises a release bearing connected to an operation mechanism for applying an operating force to the bearing in axially outward direction, and including an inner race which is provided with an axially inwardly extending cylindrical extension. A cylindrical wedge collar is disposed around the extension. A lever plate is connected to a diaphragm spring of the clutch and disposed around the wedge collar. The wedge collar and the lever plate are movable through predetermined axial section relatively to each other. The wedge collar includes an inner engagement portion axially immovably engaging the cylindrical extension, an outer engagement portion engaging the lever plate and radially elastically deflectable portion, so that radially outward deflection of the deflectable portion may permit radial movement of the inner engagement portion to a disengaged position and that radially inward deflection thereof may permit radial movement of the outer engagement portion to a disengaged position.

Release bearing mechanism of a clutch

Release mechanism for a clutch

A friction clutch includes side plates connected to an output hub and being adapted to receive a torque through a friction facing from a flywheel of an engine, and a clutch cover supporting a control mechanism of the clutch. At least one of the clutch cover and the side plates is integrally provided at outer peripheral portions with small portions which are surrounded by a groove and a slot connected to the groove so that one or more of the small portions can be removed for balancing the clutch in an unbalance-correcting process. The side plates are rigidly connected together by stop pins and are connected to the hub through springs disposed in openings formed in the side plates and a radial flange of the hub. One of the side plate is provided at outer peripheral portions circumferentially between the openings and the stop pins with the small portions.

Friction clutch and cover with balancing means

A fastening method of friction facing for clutch disc assembly, wherein projections which are able to directly hold a cushioning plate in a sandwich manner, are formed on a mold for forming friction facings, the friction facings are formed into desired shapes within said mold and said friction facings are always fastened to said cushioning plate correctly by providing a correct holding position of said cushioning plate by means of the mold while heating and pressing said mold.

Fastening method of friction facing for clutch disc assembly

A clutch disc assembly with a balancing device includes a disc adapted to be connected to an output shaft; a supporting plate device provided at the outer peripheral portion of the disc; a pair of friction facings fixed to both surfaces of the plate device; and a rivet for correcting an unbalance of an inertial mass of the disc assembly around the output shaft and fixed to the plate device. The facing may be provided with a port in which the rivet for correcting the unbalance is disposed, and a friction facing piece is disposed in the port to form a part of a friction surface.

Clutch disc assembly with balancing means

The present invention discloses a clutch disc comprising a hub means having an inner hub adapted to be connected to a shaft and provided with outer teeth and an outer hub having a flange and inner teeth meshing with the outer teeth of the inner hub with circumferential spaces therebetween; weak elastic means disposed in some of the spaces to circumferentially connect the outer and inner teeth together, other spaces in which the weak elastic means are not disposed having circumferentially shorter length than the spaces for the elastic means so that the elastic means may be prevented from full compression; stopper means for preventing both hubs from relative axial movement and preventing the elastic means from dropping out of the spaces; a pair of side plates disposed at both sides of the flange and connected to a torque input member; and strong elastic means for connecting the side plates to the flange.

Clutch disc

The present invention discloses a clutch disc comprising a hub adapted to be connected to a shaft and provided at the outer periphery with an integral radial hub plate; a pair of hub flanges made of sheet metal, disposed at opposite sides of the hub plate with friction members therebetween and fitted at the inner peripheries onto the outer periphery of the hub; a stud pin connecting radially inner portions of the flanges together and projecting through a circumferentially long aperture in the hub plate; fixing means fixing radially outer portions of the flanges radially outside the hub plate together; weak elastic means disposed in openings provided in the flanges and the hub plate and circumferentially connecting the flanges and the hub plate together; side plates fixed together and disposed at outsides of the flanges with friction members therebetween; and strong elastic means disposed in openings in the flanges and the side plates and connecting the flanges and the side plates together.
