1. A multiple speed power transmission, particularly for motor vehicles, comprising:
- an input;
a first layshaft driveably connectable through a first power to the input, and supporting a first pinion thereon;
a clutch for alternately connecting and disconnecting the input and first layshaft;
a first coupler for releasably coupling the first pinion and first layshaft;
a second layshaft driveably connected through a second power path and a one-way drive connection to the input, supporting a second pinion thereon;
a second coupler for selectively releasably coupling the second pinion and second layshaft; and
an output shaft supporting a gear thereon, said gear being in meshing engagement with the first pinion and second pinion.

Abstract
A power transmission for a motor vehicle includes an input, a first layshaft, a second layshaft; a first power path for transmitting power between the input and first layshaft, and producing a first ratio of a speed of the first layshaft and a corresponding speed of the input, a second power path for transmitting power between the input and second layshaft, and producing a second ratio of the speed of the second layshaft and corresponding speed of the input; and a clutch for releasably connecting the input and first power path.

14. A multiple speed ratio power transmission, particularly for motor vehicles, comprising:
-
an input;
a first layshaft driveably connectable through a first power path to the input, supporting a first pinion and a first set of pinions thereon;
a clutch for alternately connecting and disconnecting the input and first layshaft;
a first coupler having a selectable coupling member supported for movement on the first coupler, the first coupler releasably coupling a pinion of the first pinion set and said first layshaft in response to movement of the coupling member;
a second layshaft driveably connected through a second power path and a one-way drive connection to the input, supporting a second pinion and a second set of pinions thereon;
a second coupler having a selectable second coupling member supported for movement on the second coupler, the second coupler releasably coupling a pinion of the second pinion set and said second layshaft in response to movement of the second coupling member; and
an output supporting a gear thereon, said gear being in meshing engagement with the first pinion and second pinion, and further supporting a set of gears thereon, each gear of said set of gears being in meshing engagement with a pinion of the first pinion set and a pinion of the second pinion set. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
