1. A transmission device, in particular for rotating wheels of a wheeled vehicle, said device comprising:
a housing,
two electric motors positioned outside the housing and each provided with a drive shaft at least partially protruding inside the housing,
an output shaft made up of at least two coaxial shaft sections mounted free to rotate relative to each other,
a mechanism for transmitting motion configured to transmit the rotational motion of one of the drive shafts to one of the shaft sections of the output shaft and the rotational motion of the other drive shaft to the other or another shaft section of the output shaft, the transmission mechanism and the output shaft being at least partially accommodated inside the housing,
wherein the housing is at least partially made from a synthetic material, in that the motors are connected to each other by at least one add-on connecting element extending from one motor to the other to form a connecting bridge between said motors, and in that the transmission device comprises at least one stop for limiting the rotational movement of the assembly formed by the motors and the connecting element(s) about an axis parallel to at least one of the drive shafts.
