ABSTRACT:
A wheel drive for agricultural or industrial utility vehicles includes an electric motor with an output shaft which drives a final drive gearbox that reduces the rotational speed of the driven wheel. A transmission gearset is arranged between the electric motor and the final drive gearbox, and can be shifted between at least two rotational speed transmission ratios. The wheel drive permits attainment of a wide range of vehicle speeds with the use of low cost commercially available electric motors. The design speed of the electric motor corresponds with the principal operating speed of the vehicle and relatively high vehicle speeds are possible.
