摘要： A coupling includes left and right side members, and a centre member that is disposed between the side members. The centre member has a main axis of rotation, and includes holes disposed about the main axis at a radius. The side members each have a common offset axis of rotation parallel to and offset from the main axis. Each side member includes holes congruent with the holes in the centre member and disposed about the offset axis at the radius. Torque transfer elements extend through the holes of the centre member and into the holes of the side members. The torque transfer elements rotate about a third axis parallel to and disposed midway between the main axis and the offset axis, and transfer torque between the centre member and the side members through rolling contact between the torque transfer elements and the holes of the centre and side members.

One of the opposing surfaces includes concentric V-grooves configured to mesh with the V-grooves of one of the end members. Another of the opposing surfaces includes concentric V-grooves configured to mesh with the V-grooves of another of the end members.

摘要： A coupling comprises at least two inter-connected torque couplings. Each torque coupling includes a pair of clutch end members, a clutch centre member disposed between the clutch end members, and an actuator coupled to one of the end members. The end members and the centre member each includes a set of concentric V-grooves each disposed on a respective face thereof. The centre member is axially movable between the end members. The actuator is configured to simultaneously couple the end members to the centre member by engaging the V-grooves of both of the respective end members with the V-grooves of the centre member. The centre member of one of the torque couplings comprises one of the opposing surfaces of the one torque coupling, another of the opposing surfaces of the one torque coupling and one of the end members of another of the torque couplings.

摘要： An automotive accessory drive linkage is provided with a one-way clutch mounted on any of the pulleys carried by the engine crankshaft, an alternator, an hydraulic pump or generally, on the pulley for any other accessory operated by a belt linked to the engine in order to isolate such driven elements from oscillations in the engine speed.A spiral one-way clutch especially suitable for incorporation in automotive accessory drive system pulley has a high indexing capacity. Such clutch, installed between the pulley shive and spindle operates to suppress belt oscillations during low speed engine operation, placing less critical demands on a belt tensioner, if present. It also operates to prevent belt slippage during periods when the engine is forced to decelerate rapidly during up-shifts of the transmission, effectively eliminating "belt squeal".

摘要： An infinitely-variable transmission comprises a rotational input member, a rotational output member, first and second non-circular driving gears coupled to one of the rotational members, and a plurality of variable velocity-ratio gear assemblies disposed about the one rotational member. Each gear assembly comprises an intermediate shaft including first and second non-circular driven gears respectively meshing with the first and second non-circular driving gears. Each gear assembly also comprises a multi-directional coupling associated with the pair of first driven/driving gears and the pair of second driven/driving gears, and an actuator for coupling the first and second variable-ratio gear pairs to the rotational members. The transmission also includes a phase angle variator associated with the variable-ratio gear pairs for varying the rotational angular displacement between the first gear pairs and the second gear pairs of each gear assembly so as to vary the velocity ratio of the transmission as needed.
