Abstract: A transmission gearing arrangement includes four simple planetary gear sets, three brakes, and four clutches. The transmission produces two reverse gear ratios and twelve forward speed ratios in response to engagement of the brakes in clutches in combinations of three. The transmission is suitable for use with a range selector. In a low range, one of the reverse ratios and all twelve of the forward ratios are utilized. In a high range, the other reverse ratio and eleven of the forward ratios are utilized.

Abstract: A continuously variable transmission includes four shift elements to establish three forward driving ranges and one reverse driving range. Two of the forward driving ranges utilize recirculating power flow paths in which the power transmitted through the variator is much smaller than the power transmitted by the transmission. Both variator sheaves rotate about axes that are offset from the input axis such that neither sheave is partially submerged in transmission fluid.

Abstract: 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.

Abstract: 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.
