Patent number: 7377871Abstract: A power transfer unit is provided with a torque limiting coupling that limits the amount of torque that can be transferred to the driveline components when torque peaks occur while torque is transferred to the non-slipping wheels. The torque limiting coupling includes an engagement member disposed between an input from a driving member and an output to a driven member. The engagement member is located radially between and provides a frictional engagement between the input and the output. The engagement member is capable of slipping under heavy torque loads in order to protect the driveline components.Type: GrantFiled: February 14, 2007Date of Patent: May 27, 2008Assignee: Magna Powertrain USA, Inc.Inventor: Thomas C. Bowen

Patent number: 6715379Abstract: An all terrain vehicle comprising a V-belt continuously variable transmission and a gear-type transmission, being capable of transmitting drive torque from an engine with controlled engine braking but without loss of the torque, thereby giving a rider an improved driving feel. The V-belt continuously variable transmission and the gear-type transmission are placed in this order from upstream in a power transmission path from the engine to wheels. A one-way clutch for transmitting only the drive torque from the engine to the wheel and a torque limiter for transmitting the torque less than a predetermined value are arranged in parallel, between, e.g., a countershaft and forward intermediate gears fitted onto the countershaft.Type: GrantFiled: April 18, 2002Date of Patent: April 6, 2004Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Akio Miguchi, Yasutaka Kobayashi

Patent number: 5791579Abstract: An overload prevention clutch assembly features input and output members connected by a coupling member, which is resiliently deformable under the control of threaded fasteners to vary the torque which may be transmitted between the input and output members across the coupling member. The fasteners serve to mount the coupling member on the output member, whereupon the coupling and output members cooperate to mount the input member in assembled relationship therewith.Type: GrantFiled: September 3, 1996Date of Patent: August 11, 1998Assignee: Columbus McKinnon CorporationInventors: Julian J. Raphael, Neil S. Pennington

Patent number: 4606444Abstract: A spring operated clutch having an input subassembly and an output subassembly. The input subassembly includes a sleeve member fixedly interconnected with an input drive shaft and provided with a double conical resilient frictional member on an outer cylindrical surface thereof. A first brake member is movably disposed within a bore of a second brake member, each of the brake members having frustoconical surfaces cooperating with one of two frustoconical surfaces of the frictional member. An adjusting member is movably interconnected with one of the brake members and a spring is interposed the adjusting member in the first brake member so as to bias the brake members into engagement with the friction member. The output subassembly includes an annular armature member having a first set of teeth extending therefrom and engageable with a second set of teeth which extend from the first brake member.Type: GrantFiled: August 3, 1983Date of Patent: August 19, 1986Assignee: Facet Enterprises, Inc.Inventor: Thomas C.

Patent number: 4566570Abstract: An overload clutch wherein a clutch hub and a clutch sleeve are brought into and out of driving engagement by spring loaded driving members in the hub engaging into recesses in the sleeve. The disengagement of the clutch is achieved in stages by constructing the recesses so that the driving members will disengage individually at different torque transmission levels. More specifically, the depth of the recesses is varied to vary the disengagement levels of the driving members.Type: GrantFiled: August 18, 1983Date of Patent: January 28, 1986Assignee: Jean Walterscheid GmbHInventor: Hubert Geisthoff

Patent number: 4542812Abstract: A variable torque slip clutch is disclosed in which first and second members configured with first and second surfaces of revolution respectively transverse to an axis are positioned for sliding contact between the surfaces of revolution. A bias spring in the form of a warped disc is positioned to urge the surfaces together and a disc shaped retainer cooperates with one of the first and second members to variably compress the bias spring. The member which cooperates with the retainer is configured with ramp surface segments having a plurality of protrusions thereon angularly spaced about the axis. The retainer is configured with tongues which engage the protrusions so as to permit rotational repositioning of the retainer relative to the member with which it cooperates only after axially displacing the retainer relative to the member.Type: GrantFiled: March 5, 1984Date of Patent: September 24, 1985Assignee: Honeywell Inc.Inventor: Curtis E.

Patent number: 4346633Abstract: The invention is concerned with a spark plug wrench with provision for adjustment of the torque, the wrench comprising two toothed discs (2, 3) supported within and at one end of a cylindrical housing (1), these discs being provided at their confronting faces with teeth (5) of a form such that, when screwing-out takes place sharply dependent flanks of opposed teeth are applied together to transmit the full force while, when screwing-in takes place, slippage is allowed between the teeth. In one embodiment the inner lying toothed disc (3) is arranged on an axially displaceable attachment spindle (6) and held against rotation. At the opposite end of the housing (1) is a threaded disc (10) with an adjusting ring (11), and the last-mentioned toothed disc (3) is axially displaceable and has a pack of spring washers (16) thereon to produce the required pressure between the discs (2, 3) for transmitting a pre-set torque.Type: GrantFiled: October 20, 1980Date of Patent: August 31, 1982Inventor: Rene Rendl
