Abstract
An electric-motor-driven rigid axle for vehicles. The axle has a body with wheel carriers and points for attachment to a vehicle frame such that, in a cross-section, an upper end of the body faces the frame and a body axis forms a vertical axis extending toward the upper end and intersecting the wheel axis. The axle has electric motors and offset transmissions. The motors drive respective carriers. The transmissions are respectively interposed between the associated motor and carrier. The transmissions enable the shafts of the respective motors to be offset from the wheel axis. The transmissions are arranged such that, in the cross-sectional view, the motor shafts and the wheel axis form intersection points on an offset line which is at an angle of between 1 and 90 degrees to the vertical axis and the vertex is at an intersection point between the wheel axis and the offset line.
