摘要： Provided is a friction transmission device having a friction transmission mechanism that transmits power by contact between a take-out member from which output rotation is taken out and a plurality of friction rolling elements. The take-out member has a contact surface inclined with respect to an axial direction. The device includes an output member that is used to transmit the output rotation to a driven device, and a coupling that connects the take-out member and the output member to each other. The coupling is configured to be more easily deformed than the take-out member and the output member with respect to an axial load, and has a function of absorbing deviation of an axial center between the take-out member and the output member and a function of converting a torque acting on the output member into an axial force to transmit the axial force to a take-out member side.

摘要： Systems and methods for operating a driveline system are disclosed and include a step-variable transmission. A continuously variable transmission (CVT) is coupled between an input source and the step-variable transmission. The CVT receives a first torque from the input source and outputs a second torque. The CVT has a plurality of planetary members in rolling contact with an inner race and an outer race. A radial distance between the planetary members and a drive-transmitting member corresponds to a transmission ratio of the CVT.

摘要： A variator unit of a power-split continuously variable transmission device is fixed to a rotationally fixed component and has a primary side rotationally fixed to an input shaft and a secondary side rotationally fixed to each respective first element of the first and a second planetary gear sets via a third shaft. A third element of the first planetary gear set is rotationally fixed to a third element of the second planetary gear set via a fourth shaft and is fixable to the rotationally fixed component via a first shift element. A fifth shaft is rotationally fixed to a second element of the second planetary gear set, which is fixable to the rotationally fixed component via the third shift element, and is connectable to the input shaft via the second shift element. A second element of the first planetary gear set is rotationally fixed to the output shaft.

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.

摘要： An infinitely variable transmission capable of shifting from infinity to zero speed ratios in forward and reverse is provided. The transmission offers reciprocal blocking and supports high torque and power, while requiring a fixed number of planetary gears and a hydraulic flow control, without brakes and/or clutch by varying the angular displacement or rotational movement separating the contained vectors (speed and torque) to exploit, in a reciprocal manner, the working flow by maintaining the full potential of the movement force source without a continuity flow break-up.

摘要： A speed based axial force generation mechanism may generate axial force corresponding to a rotational speed of a speed based axial force generation system relative to a central axis. As the speed based axial force generation system rotates at increasing speeds, inertia causes a change in the configuration of a first rigid member and a second rigid member, resulting in a change in the axial force generated by the mechanism.
