Abstract (en)

[origin: EP1199237A1] The gearbox, for rail vehicles, has a summation gearing (22,22A) at each axle for the left and right (8) wheels, to overlay the drive (4) in the same direction of rotation as one wheel and the steering drive (6). The steering drive can impose a difference rotary speed on the wheels when the rail vehicle can be steered into a branch line. Each summation gearing has an input (20) from the drive motor and an input (32) from the steering drive, and a drive transmission (30) to the wheel. The second inputs (32,32A) are coupled together by a deflection stage (54,54A,56) so that they have the same rotary speed but in opposite directions.
