Classification: CPC F | IPC F

Claim 9:
10. A transmission comprising:
an input shaft arranged for rotation about an axis, a first splined tube and a second splined tube coupled to the input shaft for rotation relative to the input shaft about the axis, a first input gear mounted on the first splined tube and a second input gear mounted on the second splined tube;
an output shaft spaced apart from the input shaft, first and second output gears coupled to the output shaft and each of the first and second output gears engaged with a respective one of the first or second input gears; and
a clutch arrangement comprising:
a first coupler mounted on the first splined tube for rotation with the first input gear, the first coupler including an outer member and an inner member;
a second coupler mounted on the second splined tube for rotation with the second input gear, the second coupler including an outer member and an inner member; and
an input-gear selector mounted for rotation with the input shaft and positioned between the first and second couplers, the input-gear selector including an outer hub, a first inner hub facing toward the first coupler, and a second inner hub facing toward the second coupler, the first and second inner hubs movable relative to the outer hub,

wherein the input-gear selector is movable on the input shaft relative to the first and second couplers, engagement of the input-gear selector with the first coupler drives rotation of the first input gear with rotation of the input shaft, and engagement of the input-gear selector with the second coupler drives rotation of the second input gear with rotation of the input shaft.
