Abstract: Multi-mode friction clutch having a plurality of interleaved clutch plates operable for establishing gear ratios in planetary and countershaft type automatic transmissions and operative to provide smooth and self-synchronized shifting without the use of one-way roller or sprag clutches. Gear thrust forces from associated helical gearing and opposing hydraulic pressure forces are used to regulate the hydraulic pressure of a piston chamber by shifting an annular control sleeve which controls fluid exhaust from the chamber to maintain a direct relationship between the torque capacity of the clutch and the variable torque it actually carries. Consequently, the clutch is automatically released when the transmitted torque diminishes to zero or reverses. The clutch is applied in a normal lock mode for predetermined gear ratios, set in one-way mode for shifting and totally released when the shift is completed.

Within the series, the variation stage encompasses a range of permissible sizes (B.sub.i =B.sub.1 . . . B.sub.m) which in each case have the same centre distances (A.sub.i =A.sub.1 . . . A.sub.m).

The driven gear is in meshing engagement with a drive gear which is detachably mounted on a cam shaft rotated by the engine.

Abstract: A transmission that uses a gear set in the form of a pair of gears stacked rigidly together to couple a driving gear to a driven gear has its ratio determined by the relative number of teeth of the stacked gears and the gears with which the stacked gears mesh. If the number of teeth of either or both gears in the stack is varied, the axle of the stack must be moved to a different location in order to keep all of the pairs of gears meshed. The transmission has two or more axle-receiving locations to receive the axles of stacks effecting different ratios. To simplify assembly, the stacks are color-coded according to the ratios they effect. Stacks of the chosen color will only fit in one axle location. The selected stack may be enclosed in the transmission housing so that its color code will not be visible after assembly of the transmission.
