摘要： Embodiments are directed to a front end accessory drive (FEAD), subassemblies, and components therefor. Embodiments disclosed cover power modulating devices (PMD) which can be used in a FEAD. In one embodiment, a continuously variable transmission (CVT) is coupled directly to a crankshaft of a prime mover, and the CVT is used to regulate the speed and/or torque delivered to an accessory. A compound drive device includes a motor/generator subassembly cooperating with a CVT subassembly to provide a motor functionality with torque multiplication or division, or alternatively, a generator functionality with torque multiplication or division. In some embodiments, a FEAD includes a PMD having a sun shaft configured to couple to a sun of the PMD and to an electric motor component, such as an electrical armature or an electrical field. In one embodiment, the electrical armature the electrical field are placed concentrically and coaxially and configured to rotate relative to one another in opposite directions.

摘要： Traction planets and traction rings can be operationally coupled to a planetary gearset to provide a continuously variable transmission (CVT). The CVT can be used in a bicycle. In one embodiment, the CVT is mounted on the frame of the bicycle at a location forward of the rear wheel hub of the bicycle. In one embodiment, the CVT is mounted on and supported by members of the bicycle frame such that the CVT is coaxial with the crankshaft of the bicycle. The crankshaft is configured to drive elements of the planetary gearset, which are configured to operationally drive the traction rings and the traction planets. Inventive component and subassemblies for such a CVT are disclosed. A shifting mechanism includes a plurality of pivot arms arranged to pivot about the centers of the traction planets as a shift pin hub moves axially.

摘要： A traction-drive system that in one embodiment comprises an idler rotatable about a longitudinal axis, a plurality of rotatable and generally disc-shaped planet rollers each having an inner contact surface, a case contact surface and an idler contact surface, the inner contact surface being of a first diameter, the case contact surface being of a second diameter, and the idler contact surface being of a third diameter, the planet rollers distributed about the idler and each planet roller contacting the idler at its respective idler contact surface. The traction drive system of this embodiment also comprises an inner ring rotatable about the longitudinal axis adapted to contact the inner contact surface of each of the planet rollers, and a case ring adapted to contact the case contact surface of each of the planet rollers. In some embodiments, the inner contact surface of each roller only contacts the inner ring, the case contact surface of each roller only contacts the case ring and the idler contact surface of each roller only contacts the idler.

摘要： A continuously variable transmission (CVT) having a main shaft configured to support and position various components of the CVT. Shift cam discs cooperate with ball-leg assemblies to shift the transmission ration of the CVT. Load cam discs, a torsion disc, rolling elements, and a hub cap shell are configured to generate axial force, transmit torque, and manage reaction forces. In one embodiment, a splined input shaft and a torsion disc having a splined bore cooperate to input torque into the variator of the CVT. Among other things, various ball axles, axle-ball combinations, and reaction force grounding configurations are disclosed. In one embodiment, a CVT having axial force generation means at both the input and output elements is disclosed.
