Abstract

The invention relates to an electrical individual wheel drive having several electromotors (1) whose input power is combined by a spur gear assembly (2) and one rear-mounted planetary gear (3) which adapts the input torque and the wheel speed. The wheel bearings (4) are mounted axially between the electromotors (1) and planetary gear (3). One brake (7) is a pneumatically or hydraulically actuated disc brake and acts as service, parking, emergency and auxiliary brake.
