A clutch brake having a hub flange with a brake assembly installed between two cover elements forming a cover assembly, external friction surfaces on the cover elements, recessions formed on an outer peripheral part of the hub flange, centrifugal segments urged by a centrifugal force toward radial outsides of the hub flange installed in the recessions and spring members in the recessions urging the centrifugal segments radially outwardly of the recessions for generating an initial torque between the centrifugal segments and the hub flange.

A pull-type clutch for connecting a flywheel to a transmission and having clutch discs spline fitted onto an input shaft of the transmission, a sleeve on the outer periphery of the input shaft, a release bearing fastened to the transmission end of the sleeve, a flange portion formed on the flywheel end of the sleeve and projecting toward the outer periphery, a load transmitting retainer on the sleeve pressed to the flange portion, a clutch cover connected to the flywheel and covering a pressure plate for pressing the clutch discs into engagement with the flywheel, a disc-formed spring member disposed between the clutch cover and the retainer, levers for transmitting spring force of the spring member disposed between the retainer and the pressure plate at plural circumferential locations and pins between the retainer and the clutch cover for sliding movement of the retainer relative to the clutch cover.

Modular clutch construction in which a clutch cover assembly, concentrically containing a pressure plate actuating a clutch disc assembly, is fixed to the flywheel of an engine as a modular unit. The construction improves the modular connection between the clutch cover peripheral wall and the flywheel; in particular through the use of pins to restrain the cover from whirling relative to the flywheel, and by a taking advantage of a method of starter ring-gear installation in which the gear is shrink-fitted over the flywheel with the clutch cover peripheral wall intervening, such that the circumferential end margin of the clutch cover is simultaneously clamped between the ring gear and the flywheel cylindrical surface. The clutch cover is thus secured onto the flywheel in an assembly stage of reduced steps, by comparison with methods employing bolts or other fasteners as the primary connecting means. The modular connection can further be by matching mortise and tenon forms, or by mutually engaging threads, in corresponding portions of the flywheel and the clutch cover.

The pull-type clutch 1 basically includes a clutch disc assembly 4, a clutch cover assembly 5, a cylindrical or tubular member 21 and a release mechanism 6. The pull-type clutch 1 is designed to restrain the rotational engagement between the release mechanism 6 and the input shaft 3 of the transmission. The cylindrical member 21 is fixedly coupled to the front cover 7 of the transmission and extends around the input shaft 3 in the radial direction spaced apart. The release mechanism 6 is a mechanism for releasing the biasing force by the diaphragm spring 14 of the clutch cover assembly 5. The release mechanism 6 has a sleeve 23 and a bearing 24. The sleeve 23 is supported on an outer surface of the cylindrical member 21 for axial movement. The bearing 24 is disposed within the clutch cover 11 and is located between the sleeve 23 and the retainer 13.

摘要:
A pull-type clutch having an inner peripheral part of a diaphragm spring sandwiched between a lever plate and a retainer plate both being installed at an outer periphery of a release bearing. The lever plate has a cylindrical body and a radial outer flange at an axial forward side of the cylindrical body and the retainer plate has a disc-like annular body and a plurality of claws extending in radial inward direction and a plurality of projections extending in radial inward and axial forward directions, at an inner periphery of the disc-like annular body with spaces left therebetween. A groove is formed on an outer periphery of the cylindrical body of the lever plate and the tip ends of the claws fit in the grooves so as to secure the retainer plate to the outer periphery of the cylindrical body. The inner peripheral part of the diaphragm spring is sandwiched between the flange and the disc-like annular body radially outside of the projections.

A modular clutch includes a flywheel 2, a clutch cover assembly 3 and a clutch disk assembly 4, which form a single module that in one embodiment is installed directly onto the crankshaft of an engine, and in an alternate embodiment is attached to a flex plate. The modular clutch is configured to be installed and replaced as a unit. The clutch cover assembly 3 has a clutch cover 21, a pressure plate 22 and diaphragm spring 23. The clutch disk assembly 4 has a clutch engagement portion 31 made of a metallic sintered body.

A clutch cover assembly (1) has release load characteristics which have been smoothed out or flattened by using a secondary conical spring (8) in combination with a diaphragm spring (7). To reduce the overall number of parts in the assembly 1, the pressure plate (6) includes axially extending pins (10) which extend through holes formed in the diaphragm spring (7). The pins (10) are also engaged with a portion of the conical spring (8).
摘要:
A clutch cover assembly, in which a radially inner side spring force action point (an inside projection 44, for example) of a lever 40 is provided at a position radially inward from an outer peripheral edge 33 of a diaphragm spring 30. A radially outer side spring force action point (an outside projection 46) of the lever 40 is positioned at a distance B between a rotation center O1 of the lever 40 and the outer side spring force action point shorter than a distance A between the rotation center O1 and the inner side spring force action point. The lever 40 is adapted to multiply a spring force P of the diaghragm spring 30.The reaction force action point of the diaphragm spring 30 is shifted to an outer peripheral part of the clutch cover 16, so that a deflection of the clutch cover 16 is reduced and a release efficiency is improved.
