  • Publication number: 20190323582
    Abstract: Provided herein is a continuously variable planetary (CVP) having a plurality of balls, each ball having a tiltable axis of rotation, each ball in contact with a first traction ring and a second traction ring, the CVP including a carrier assembly supporting each ball, the carrier assembly comprising a first carrier member and a second carrier member; an idler located radially inward of, and in contact with, each ball; and a first axial positioning mechanism coupled to the idler and the first carrier member, wherein the first axial positioning mechanism adjusts the axial position of the idler during operation.

  • Publication number: 20180187624
    Abstract: Provided herein is a method and control system for a multiple-mode continuously variable transmission having a ball planetary variator. The control system has a transmission control module configured to receive a plurality of electronic input signals, and to determine a mode of operation from a plurality of control ranges based at least in part on the plurality of electronic input signals. The transmission control module includes a CVP control module. In some embodiments, the transmission control module is adapted to include an engine braking control process. The engine braking control process is configured to adjust the variator corresponding to an engine braking request.

  • Publication number: 20080039270
    Abstract: 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.
