Definitions

  • the invention refers to a new motive axle system with moveable independent wheels for railway vehicles, which can be used on tracks of different gauges.
  • wheel set systems which have axially movable wheels which allow a railway vehicle to travel on tracks of different gauges.
  • the applicant has developed different systems of this type among which, for example, is that disclosed in patent FR-A-1 558 329 , which refers to a single-axle bogie with variable separation between the wheels.
  • the object of the system of the present invention is to provide a movable independent wheel axle of the type which forms part of a TALGO® wheel set or the like, which also incorporates the motive axle function of the type belonging to a railway system of disseminated or distributed traction.
  • the system in accordance with the invention is basically comprised by: a short axle whose journal is assembled on a load supporting part with a first interposed bearing; a tubular part assembled on and joined to said axle, on one of whose ends a wheel is attached, said tubular part having an end area opposite to that on which the wheel is mounted, of greater diameter and with an outer straight-toothed gearing; a second bearing attached to the tubular part towards the middle of the total length of the latter, with axial bearings arranged on each side of the same; a bearing box which houses said second bearing and said axial bearings, which is provided, on its front and rear walls, with protuberances which co-operate with the rods of a bolt which immobilises the wheel in positions corresponding to the different track gauges; and a hollow axle floating system which at one of its ends engages with said outer gearing of the first end of said tubular part and which is adapted to communicate to the latter the drive transmitted from a traction motor by means of a bevel gear assembly,
  • said load supporting part on which the journal of the axle is assembled and said box which houses said second bearing and said axial bearings form part of a load supporting frame which joins them together.
  • journal of a short axle E is indicated by 1, attached to a bearing 2 which supports the vertical load transmitted through the frame 3.
  • This bearing is housed in the outer bearing box, which is also provided with a sliding piece 13 whose function will be explained below.
  • tubular part 4 to which, at the end which is next to the outer bearing box, a wheel R is attached which is joined to the said tubular part 4.
  • the opposite end of the tubular part 4, indicated by 5 in Figure 1 has an area of enlarged diameter provided, on its outer surface, with a straight-toothed gearing 5', intended to engage with an inner gearing 6' provided in the inner side of the end of a section 6 of a hollow axle floating system generally designated by H.
  • the arrangement of the part 4, the wheel R and the bearings 7, 8 is such that the whole assembly can slide axially jointly with the axle E while the teeth of gearings 5', 6' remain constantly in a meshing condition.
  • the section 6 of the hollow axle floating system H is made to rotate by the conical group made up of the pinion 11, joined to the power shaft of a traction motor (not shown) , and the crown 12, attached to the outer covering HE of said hollow axle floating system H.
  • Figure 1A shows a cross-section view taken through the line A-A of Figure 1 , representing in greater detail the assembly of the bearing box 9, which encloses the bearings 7, 8, by sliding into the housing 16 made for this purpose in the supporting frame 3.
  • said bearing box 9 co-operates with a locking bolt 14 on which a part 15 will act, which is provided in the track in order to achieve the change of track gauge of the railway vehicle.
