摘要:
A double clutch arrangement for use in a transmission (10) or other place where a mechanical clutch is desired that has a high torque capacity and small engagement and disengagement forces at the shift lever. The clutch arrangement is utilized on the output shaft (25) of a two-position clutch having forward and reverse gears (31,32) and includes a ball screw actuated clutch mechanism (35,36,37,38,39,45) positioned between the shaft and an externally actuated encompassing shift collar (38) in combination with a friction clutch mechanism. The friction clutch mechanism comprises either a pair of clutch friction packs (49,51) positioned between the shift collar (38) and the forward (31) and reverse (32) gears or a pair of cone clutches (82,83,84,85) therebetween. Initial actuation of the forward or reverse friction pack or cone clutch will initiate the ball screw clutch mechanism to lock up the clutch in either direction.

Bei einem Spindelantrieb mit einer Spindel (7) und einer Mutter ist einer dieser beiden Teile mittels eines Antriebes antreibbar und der andere Teil in Richtung der Achse (10) der Spindel (7) in eine Endposition bewegbar, wobei der in axialer Richtung bewegbare Teil an einer Verdrehsicherung (19) geführt ist und eine Schaltkupplung (18) in Kraftfluß zwischen der Verdrehsicherung (19) und dem Antrieb eingebaut ist. Um bei Erreichen der Endlage bei Versagen eines Endschalters zum Abschalten des Antriebes eine Zerstörung des Spindelantriebes zu vermeiden, - weist die Schaltkupplung (18) eine Außenhülse (21) auf, die mit zwei an ihr unverdrehbar angeordneten Sägezahnringen (37, 38) versehen ist, deren Sägeverzahnungen einander entgegengesetzt gerichtet sind und mit in entgegengesetzter Drehrichtung sperrenden Sägezähnen (39, 40) ausgestattet sind, - weist die Schaltkupplung (18) weiters einen innerhalb der Außenhülse (21) liegende Innenteil (30) auf, mit dem zwei Gegen-Sägezahnringe (42, 43) mit jeweils einer zu einer der Sägeverzahnungen der Sägezahnringe (37, 38) in und außer Eingriff bringbaren Gegen-Sägeverzahnung unverdrehbar verbunden sind.
摘要:
A positive drive having a housing (10) retaining a pair of spaced drive clutches (54) and (56) used to lock axles (18) and (20) respectively to housing (10) for one-to-one rotation. The clutches move from the engaged to the disengaged mode via axial movement of drive couplings (30) and (32) which are forced to the respective engaged positions by a shaft (48) secured for rotation with the housing. The shaft acts on cams (38) and (40) on the drive couplings to cause rotational and axial movement of the couplings. Rotational movement of one drive coupling relative to the other drive coupling is prevented by a balking clamp (76). The clutches (54) and (56) are inserted within the housing through a window (14). The axles are retained by "C" clips (80) contacting spline couplings (26) and (28).

Various embodiments of a coupling are disclosed. The coupling can include a barrel that includes a communication pathway, such as an electrical contact or optical pathway. The coupling can include a nut that is configured to engage with a corresponding portion of a mating connector, such as via a threaded connection. When the coupling and the mating connector are engaged, the nut secures the coupling and the mating connector together, and respective termination elements of the coupling and the mating connector are in communication with each other. The coupling can include a torque-limiting mechanism. The torque-limiting mechanism can be configured to enable the transmission of torque up to a limit amount, and to inhibit or prevent the transmission of torque above the limit amount.

An accessory drive tuning device with a torsion spring for angular vibration isolation and having a spring pocket that frictionally engages the end of the torsion spring. The engagement may be with a wedge-shape on either the spring end or the pocket or both, adapted so that the spring end wedges into the pocket. The engagement may be by interference fit. One or both ends of the spring may be engaged in respective pockets.

Die Erfindung betrifft einen Freilauf mit einem Innenteil (25) und einem Außenteil (2), wobei zwischen dem Innenteil (25) und dem Außenteil (2) Kupplungselemente (15, 35) vorgesehen sind, welche im Sperrbetrieb eine relative Drehbewegung des Innenteils (25) zum Außenteil (2) sperren und im Überholbetrieb die Bauteile (25, 2) freigeben. Zum Erreichen einer höheren Lebenddauer und/oder des Einsatzes von Werkstoffen geringerer Festigkeit ist erfindungsgemäß vorgesehen, dass das Außenteil (2) eine radial nach innen gerichtete, innere Konusfläche (20) aufweist und, dass das Innenteil (25) eine radial nach außen gerichtete, äußere Konusfläche (38) aufweist und, dass Stellmittel (15, 55) vorgesehen sind, durch welche im Sperrbetrieb die innere Konusfläche (20) des Außenteils (2) und die äußere Konusfläche (38) des Innenteils reibschlüssig miteinander in Kontakt bringbar sind und, dass diese Stellmittel (45, 55) beim Übergang vom Sperrbetrieb in den Überholbetrieb in eine neutrale Stellung rückstellbar sind und der Reibkontakt zwischen den Konusflächen (20, 38) aufgehoben ist.

A pulley assembly for use in an automobile accessory drive system includes a shaft engaging hub, a pulley member, a nut treaded onto the shaft engaging hub, and a brake member interposed between the pulley member and the nut. The shaft engaging hub is engaged with an accessory input shaft for rotation therewith. Frictional engagement between the pulley member, the brake member, and the nut transfers torque from the pulley member to the input shaft. The pulley member includes an inner coupling surface and a peripheral belt-engaging surface. The nut includes an outer coupling surface. The brake member includes a first coupling surface in frictional engagement the outer coupling surface of the nut and a second coupling surface in frictional engagement with the inner coupling surface of the pulley member. When torque is applied to the nut in a first direction the out coupling surface of the nut couples to the inner coupling surface of the brake member such that the hub and the nut rotate with the pulley member. The outer coupling surface of the nut and the inner coupling surface of the brake member decouple when torque applied to the nut is in a second direction opposite the first direction such that the hub rotates relative to the pulley member.
