Definitions

  • the present invention relates to a device for driving independent wheels in rotation of a railway vehicle with a driving axle, from a motor, a reduction gear and a mechanical differential.
  • the axles have a mechanical differential housed inside a beam bridge which connects the two wheels. This has the disadvantage of occupying a large space between the wheels and making it impossible to lower the vehicle floor.
  • the object of the present invention is to provide a device for driving the wheels by driving axle with a mechanical differential which makes it possible to lower the floor of the vehicle and thus make its accessibility easier.
  • the device according to the invention is characterized in that its mechanical differential is arranged outside one of the wheels, one of the output pinions of which is coupled directly to the nearest wheel, and the other of which is coupled to the other wheel via a connecting shaft.
  • Figure 1 shows a known device with differential arranged in a bridge between the wheels.
  • FIG. 2 represents a device of the invention with a differential outside the wheels.
  • the motor 1 drives through its shaft a reduction gear 2, which transmits its movement to the differential 3, arranged in a bridge 4 between the wheels 6 and 8 of the vehicle.
  • the motor half-shaft 7 at the output of the differential drives the wheel 8, and the motor half-shaft 5 the wheel 6, according to a technique analogous to that of the automobile and heavy goods vehicles.
  • the connecting shaft 20 is arranged inside a hollow fixed axle 21, around which the two rolling wheels 12 and 13 rotate.
  • the movement of the shaft of the traction motor 14 is transmitted to the wheels by means of a reduction gear 15, with two reduction stages 16 and 17.
  • Downstream of the first reduction stage 16 of the reducer is arranged a mechanical differential 18, which distributes the motor torque between the wheel 12, by means of a coupling 19, and the wheel 13 by means of the motor shaft proper 20, arranged inside the hollow fixed axle 21, and of the coupling 11.
  • the braking of the axle is ensured by a disc brake shown diagrammatically at 22 on the motor shaft.
  • the device of the invention applies to all rail vehicles with bogies with two axles or a single axle, with low floors over their entire length, more particularly to trams.
