Abstract
A friction-ring gear unit for a vehicle that is operable by motor power and/or pedaling power, in particular for an electrical bicycle having an electric motor, comprising a crankshaft for pedal cranks, and an inner friction ring (26) and an outer friction ring, as well as at least one rotatable dualcone roller which is situated on a roller carrier and is in frictional engagement with the inner friction ring and the outer friction ring, the friction-ring gear unit being situated coaxially around the crankshaft.

1-15. (canceled)
A friction-ring gear unit for a vehicle that is able to be operated using motor power and/or pedaling power, the vehicle being an electrical bicycle having an electric motor, the friction-ring gear unit comprising:
- a crankshaft for pedal cranks;
- and
- an inner friction ring, an outer friction ring, and at least one rotatable dual-cone roller which is situated on a roller carrier and is in frictional engagement with the inner friction ring and the outer friction ring;
- wherein the friction-ring gear unit is situated coaxially around the crankshaft;
- and
- wherein the friction-ring gear unit has an adjustment device for its translation ratio, which is movable along an adjustment path that extends inside a housing of the friction-ring gear unit and is at least approximately linear, by which the roller carrier is axially displaceable in relation to the friction rings.
A vehicle that is able to be operated using motor power and/or pedaling power, the vehicle being an electrical bicycle having an electric motor, the vehicle including a friction-ring gear unit and a crankshaft, which are situated concentrically to each other, wherein the friction-ring gear unit has an adjustment device for its translation ratio, which is movable along an adjustment path that extends inside a housing of the friction-ring gear unit and is at least approximately linear, by which the roller carrier is axially displaceable in relation to friction rings of the friction-ring gear unit, the adjustment device extending through the housing.
