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.
Claims6
A wheel drive having a gearwheel (2) driven eccentrically relative to a wheel axle and in intermeshing connection with an outer central wheel (5), and said outer central wheel (5) is in operative connection with a output (4, 9), and said driven gearwheel (2) is in intermeshing connection with at least two other gearwheels (6) which are in operative connection with said outer central wheel (5) and are disposed so that lines (16, 17), which are disposed perpendicular to a line of action by the peripheral forces generated by the meshing connections of said driven gearwheel (2), strike on an axis of rotation (15) of said driven gearwheel (2), wherein said outer central wheel (5) is connected with the output via a planet step (8) and an actuation device (13) of a brake (11) has an area disposed parallel to said wheel axle (12) and situated substantially within a wheel rim (10) and has an area situated at right angles with said wheel axle (12) and placed outside a wheel rim (10).
