Abstract

This invention relates to individual wheel drives for individually suspended, spring-mounted wheels of a vehicle comprising one universal joint shaft (2) connecting the output shaft socket (10) of a drive device with the input shaft socket of a wheel, having one main section (4) and at least one end section (8) situated on one end thereof, via a universal joint (6), rotatingly coupled with the associated shaft socket (10), the universal joint shaft (2) having a permanent inclination which compensates an offset between drive device and wheel, and means being provided for reducing a permanent deviation defined by the inclination. The end section (8) associated with the universal joint (6) and the shaft socket (10) coupled therewith are coupled with each other via a bevel wheel pair (16, 18), the deflection angle α of which corresponding at least partly with the corresponding permanent deflection angle between universal joint shaft (2) and shaft socket (10).
