Publication number: 20170051815Abstract: A family of transmission gearing arrangements utilize one or two ball variators to establish a continuous range of speed ratios between an input and an output. In each case, the range of speed ratios includes an infinite ratio in which the output is stationary as the input rotates. In some embodiments having two ball variators, the outputs of the variators are combining using a planetary gear set. In other embodiments having two variators, the outputs of the variators are combined using clutches, which may be switchable one-way clutches.Type: ApplicationFiled: August 21, 2015Publication date: February 23, 2017Inventors: David Allen Janson, Donald Edward Hoffman

Publication number: 20160069431Abstract: A family of transmission gearing arrangements each establish at least one reverse gear ratio and between nine and fifteen forward gear ratios. A shiftable gearing arrangement establishes a variety of speed ratios between the input and a first shaft. In some embodiments, a fixed speed ratio is established upstream or downstream of the shiftable gearing arrangement. In reverse and low gear ratios, a low clutch couples the first shaft to the output. In the high gear ratios, a combining planetary gear set establishes a linear speed relationship between the first shaft, a second shaft rotating at a speed proportional to the input, and the output.Type: ApplicationFiled: November 17, 2015Publication date: March 10, 2016Inventor: Donald Edward Hoffman
