Abstract

A wheel drive preferably used in a low-platform bus for driving the wheels is driven by a drive motor (1) eccentrically arranged relative to the wheel axle (12) and a gearwheel (2). The driven gearwheel (2) of a reduction gear (3) is in intermeshing connection with two additional gearwheels (6) and one outer central wheel (5) in a manner such that the drive torque is distributed onto the gearwheels (6) and the outer central wheel (5) and the driven gearwheel (2) can be floatingly supported so that a uniform load distribution results.
