Abstract
A driving bogie having at least one driving motor, a pair of driven wheel-and-axle units and an axle gear for each of the axles of the wheel-and-axle units rigidly connected with the bogie frame, is arranged with a hollow transmission shaft for the axle gear encircling the axle of a respective wheel-and-axle unit and with a hollow Cardan shaft rigidly connecting the hollow transmission shaft with the wheel-and-axle units through centering articulated couplings. The invention is particularly directed to the structure of the articulated couplings which are formed with a number of hinged levers and with ball joints at the ends of each of the levers, the number of the hinged levers being an even number greater than three, with half of the hinged levers being arranged in the direction of rotation of the coupling and with the other half of the hinged levers being arranged in the opposite direction.
