Patent number: 10458526Abstract: Components, subassemblies, systems, and/or methods for improving the performance and increasing the life of continuously variable transmissions (CVT). A first stator may be formed with an outer diameter greater than an outer diameter of a second stator. A stator may have radial slots formed to extend farther radially inward than slots on the other stator. The larger outer diameter of a stator or the formation of guide slots on a first stator extending farther radially inward of guide slots on a second stator may prevent egress of a planet axle from a radial slot, increase range of the CVT, allow for larger tolerances to reduce losses, and other advantages, Slots on a timing plate may be formed having a width greater than a width of guide slots formed on either stator to allow the stators to control adjustments while the timing plate avoids runaway axles. The shape, including junction between surfaces on a timing plate or stator may also prevent an axle from egressing.Type: GrantFiled: March 17, 2017Date of Patent: October 29, 2019Assignee: Fallbrook Intellectual Property Company LLCInventors: Jon M.

In one embodiment, a control system is adapted to facilitate a change in operating mode of an IVT. In another embodiment, a control system includes a drive clutch coupled to a source of rotational power; the drive clutch is configured to selectively engage a traction ring and a carrier of the IVT. The control system includes a one-way clutch assembly configured to selectively engage the traction ring and the carrier. In some embodiments, the control system governs the actuation of the one-way clutch to selectively lock and unlock components of the IVT. In some embodiments, the control system implements an IVT mode wherein the carrier selectively couples to a source of rotational power. In other embodiments, the control system implements a CVT mode wherein the traction ring selectively couples to a source of rotational power.Type: GrantFiled: March 31, 2017Date of Patent: October 1, 2019Assignee: Fallbrook Intellectual Property Company LLCInventors: Fernand A.
