Classification: CPC F | IPC F

Claim 0:
1. A transmission comprising:
an input shaft arranged for rotation about an axis, a first input gear, a second input gear, a third input gear, and a fourth input gear coupled to the input shaft for rotation relative to the input shaft about the axis;
an output shaft spaced apart from the input shaft, first, second, third, and fourth output gears coupled to the output shaft and each engaged with a respective one of the first, second, third, or fourth input gears;
a first clutch arrangement comprising a first input-gear selector mounted for rotation with the input shaft and positioned between the first and second input gears; and
a second clutch arrangement comprising a second input-gear selector mounted for rotation with the input shaft and positioned between the third and fourth input gears;
wherein the first input-gear selector is movable on the input shaft relative to the first and second input gears for selectively driving rotation of the first input gear with rotation of the input shaft in a first circumferential direction and a second circumferential direction or rotation of the second input gear with rotation of the input shaft in the first circumferential direction and the second circumferential direction; and
wherein the second input-gear selector is movable on the input shaft relative to the third and fourth input gears for selectively driving rotation of the third input gear with rotation of the input shaft in the first circumferential direction and the second circumferential direction or rotation of the fourth input gear with rotation of the input shaft in the first circumferential direction and the second circumferential direction.
