Abstract
The present invention relates to an axle, or a pair of axles forming a bogie, motorized and having wheels that rotate independently, which axle is connected to a body or a corridor connection of a vehicle either via a load-bearing cross-member, or directly via the suspension systems, the wheels of the axle being mounted to rotate independently, wherein the entire set of members that transmit motion between the motor(s) and the wheels is disposed in a load-bearing axle assembly referred to as a 'stepdown gear assembly' which simultaneously performs the functions of bearing the load, of driving the axle, and of transmitting the motor torque, wherein the motor or each of the motors has its axis parallel to the axis of the axle, and wherein a large amount of modularity exists between the single-motor version and the one-motor-per-wheel version.
