Abstract

The wheel drive module comprises a motor (9), a casing (1) partially housing the motor, a wheel support platform (22), a wheel (R) rigidly mounted on the platform, a reduction transmission (31) engaging directly between the motor and the wheel, and a single main transmission shaft (12) bearing the rotor (13) of the motor as well as an input member (35) of the transmission.The casing (1) comprises on the side of the wheel, a fixing shank (18) externally receiving a bearing for said platform (22). The length of the shank is equal to the distance (d) between the input member (35) of the transmission (31) and the free end of the rear part of the platform (22). The reduction transmission (31) is housed in the platform (22). Finally a portion of the main transmission shaft that is torsionally deformable is housed inside the fixing shank.
