Abstract
A transmission for a muscle-powered vehicle having an auxiliary motor, in particular for a pedelec, including a housing which can be fitted on the vehicle, a first drive shaft mounted in the housing for feeding in muscle power, said first drive shaft being coupled to an approximately coaxial output shaft for driving the vehicle, and further including, approximately at a right angle to said first drive shaft, a second drive shaft for connecting the auxiliary motor, which second drive shaft acts on the output shaft via an angular gear. The angular gear is formed by a crown gear on the output shaft and a sprocket on the second drive shaft, which sprocket engages in the crown gear.

A transmission for a muscle-powered vehicle having an auxiliary motor comprising:
- a housing which can be fitted on the vehicle,
- a first drive shaft mounted in the housing for feeding in muscle power,
- said first drive shaft being coupled to a coaxial output shaft for driving the vehicle,
- and further comprising, at a right angle to said first drive shaft, a second drive shaft for connecting the auxiliary motor,
- which second drive shaft acts on the output shaft via an angular gear,
- wherein the angular gear is formed by a crown gear on the output shaft and a sprocket on the second drive shaft, which sprocket engages in the crown gear, wherein the crown gear includes a flat tooth-bearing surface.
A transmission for a muscle-powered vehicle having an auxiliary motor comprising:
- a housing which can be fitted on the vehicle,
- a first drive shaft mounted in the housing for feeding in muscle power,
- said first drive shaft being coupled to a coaxial output shaft for driving the vehicle,
- and further comprising, at a right angle to said first drive shaft, a second drive shaft for connecting the auxiliary motor,
- which second drive shaft acts on the output shaft via an angular gear,
- wherein the angular gear is formed by a crown gear on the output shaft and a sprocket on the second drive shaft, which sprocket engages in the crown gear, wherein the first and second drive shafts are mounted rotatably in the housing and are axially fixed, and in that the output shaft is a hollow shaft which is penetrated by the first drive shaft, on which the output shaft is mounted axially displaceably and is coupled to said first drive shaft for conjoint rotation therewith in at least one direction of rotation, and wherein the mounting and coupling of the output shaft on and to the first drive shaft is formed by a first freewheel with rolling bearings and axial play.
A transmission for a muscle-powered vehicle having an auxiliary motor comprising:
- a housing which can be fitted on the vehicle,
- a first drive shaft mounted in the housing for feeding in muscle power,
- said first drive shaft being coupled to a coaxial output shaft for driving the vehicle,
- and further comprising, at a right angle to said first drive shaft, a second drive shaft for connecting the auxiliary motor,
- which second drive shaft acts on the output shaft via an angular gear,
- wherein the angular gear is formed by a crown gear on the output shaft and a sprocket on the second drive shaft, which sprocket engages in the crown gear, and wherein an adjusting ring mounted adjustably in the axial direction on the first drive shaft engages via an axial bearing with the side of the crown gear facing away from the sprocket.
