Patent number: 7967719Abstract: 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.Type: GrantFiled: August 20, 2007Date of Patent: June 28, 2011Assignee: Fallbrook Technologies Inc.Inventors: Robert A Smithson, Brad P Pohl, Oronde J Armstrong, Donald C Miller, Daniel J Dawe, Fernand A Thomassy, Matthew P Simister, Wesley R Poth, Jon M Nichols, Charles B Lohr

Patent number: 7959533Abstract: Inventive embodiments are directed to components, subassemblies, systems, and/or methods for continuously variable transmissions (CVT). In one embodiment, a main axle is adapted to receive a shift rod that cooperates with a shift rod nut to actuate a ratio change in a CVT. In another embodiment, an axial force generating mechanism can include a torsion spring, a traction ring adapted to receive the torsion spring, and a roller cage retainer configured to cooperate with the traction ring to house the torsion spring. Various inventive idler-and-shift-cam assemblies can be used to facilitate shifting the ratio of a CVT. Embodiments of a hub shell and a hub cover are adapted to house components of a CVT and, in some embodiments, to cooperate with other components of the CVT to support operation and/or functionality of the CVT. Among other things, shift control interfaces and braking features for a CVT are disclosed.Type: GrantFiled: October 3, 2006Date of Patent: June 14, 2011Assignee: Fallbrook Technologies Inc.Inventors: Jon M.
