Abstract:
A one-way clutch includes a clutch body and body bore. A clutch plate stack includes first, second, and third clutch plates, the first and third clutch plates fixed to the clutch body. The second clutch plate rotates axially on a longitudinal axis. The first clutch plate includes a first strut cavity and the second clutch plate includes a second strut cavity. A forward strut is rotatably connected to the second clutch plate and biased toward the first clutch plate. The forward strut when positioned in the first strut cavity defines a clutch engaged position preventing second clutch plate rotation in a first rotational direction, while allowing rotation in a second rotational direction. A reverse strut slidably disposed in a strut bore extends through the third clutch plate, is partially positioned in the second strut cavity and is displaced in the strut bore during rotation of the second clutch plate.
Abstract:
A power transmitting system that is configured to have BAS and IS functionality. The power transmitting system can be operated in a first mode in which an engine provides rotary power for driving an accessory assembly and a motor/generator. The device can be operated in a second mode for starting the engine and driving the accessory in which rotary power is output from the motor/starter in a first rotational direction. The device can also be operated in a third mode in which the motor/generator outputs rotary power in a second, opposite rotational direction for driving the accessory while the engine is not operating. A kit for a power transmitting system is also provided.
Abstract:
In a device for damping rotary oscillations in a traction mechanism drive for auxiliary units of an internal combustion engine, having an overrunning clutch (27), which is arranged between a pulley (25) and a hub (26), according to the invention a locking device (33) is located between the pulley (25) and the hub (26), axially behind the overrunning clutch (27). This locking device includes an inner ring (34), which surrounds and is secured to the hub (26), and outer ring (35), which surrounds the inner ring (34) with a radial clearance and is secured to the pulley (25), and a plurality of retaining balls (36) which, together with compression springs (37), are arranged in radial bores (39) in the outer ring (35).
Abstract:
A centrifugal frictional clutch is constituted by a rotary housing supporting for rotation a weight lever actuated by the centrifugal force and being biased by a spring against the latter. The weight lever pivotably supports a coupling jaw which cooperates with a frictional surface of a coupling disk. The resultant normal frictional force F.sub.N forms with the line connecting pivot points of the jaw and of the lever a design angle .gamma. which corresponds to the angle of the static friction. The biasing spring, the jaw and the weight lever are arranged within the range of the coupling disk. Preferably, the clutch includes an additional disk having a smaller diameter and coupled via a free-wheel coupling to the first coupling disk to act as a double speed clutch.
Abstract:
A clutch construction comprising inner and outer relatively rotatable members, and a flexible friction band interposed between said members. A plurality of separate elements are interposed circumferentially between the band and the inner member in abutting engagement with one another and otherwise being independent of each other. Force applying means is provided and is operable in response to rotation of one of said members to act on said elements and urge them radially outwardly and circumferentially to maintain said elements in abutting engagement not withstanding said radially outward movement thereof. After engagement, and upon overrunning by the other member or upon reduction in the speed of rotation of the one member, disengaging means on the one member acts on the band to disengage the drive.
