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.

Patent number: 10208840Abstract: Continuously variable transmissions (CVTs) having a plurality of balls, each ball having a bore through which a ball axle passes, are provided. In some aspects, the CVTs include first and second rings on either side and in contact with the plurality of balls, and an idler assembly including an idler having a non-uniform outer diameter. The profile of the idler ensures lubricant flows to a largest diameter of the non-uniform outer diameter, and lubricant sprays off the largest diameter to lubricate one or more components of the CVT. A lubrication system may include a scraper configured to remove lubricant that accumulates in an interior of the CVT.Type: GrantFiled: August 28, 2015Date of Patent: February 19, 2019Assignee: Fallbrook Intellectual Property Company LLCInventors: Jon M.
