Definitions

  • the object of the present invention is a suspension system of railway vehicles, especially four-wheel freight cars, consisting of a set of springs, a saddle and friction wedges.
  • Suspension systems known so far are designed in such a way that a chassis frame at both ends, and on both sides of a car is provided with base plates, where each of them is supported by a set of suspension springs mounted on a matching saddle.
  • the saddle in turn, is seated on a bearing shell of a wheel set.
  • In the central part of each base plate there is a space surrounded by surfaces that are mating with saddle columns.
  • a friction wedge is of a triangular shape, with different inclination of planes, and mating surfaces of the wedge, saddle and base plate are lined with pads.
  • the object of the present invention is to develop such a design of friction wedges that a low value of friction factor between the inclined wedge surface and mating base plate could be assured.
  • the wedge surface formed by rollers is inclined.
  • the surface formed by the rollers is inclined at an angle of 35° to the level, and the vertical surface forms a sector of a cylinder aligned with a horizontal axis.
  • the vertical surface of a one-roller wedge is lined with material having a friction factor lower than 0.2, and the wedge next to the roller is provided with a bumper, in order to hinder its rotation.
  • Springs of enhanced crosswise rigidity have been used. By dividing the springs, preferably into two parts, with a dividing plate, the rigidity of springs in use till that time was modified.
  • Dividing plates belonging to adjoining springs that support a base plate and a wedge are mutually connected, and also the dividing plates located on one side of a car are connected with the matching dividing plates that are located on the other side of the car.
  • the wedge plane is inclined to the level at an angle of 10° ⁇ 40°, preferably at 30°, and at the same time its vertical plane is inclined towards the wedge slope at an angle of up to 5°, preferably 3°.
  • the plane of the base plate that is mating the inclined wedge plane, and the saddle column plane are both lined with a material having the friction factor lower than 0.2. Springs of enhanced crosswise rigidity have been used.
  • Fig. 1 Suspension system, version 1, two-roller wedge solution
  • Fig. 2 Suspension system, version 1, one-roller wedge solution
  • Fig. 3 Suspension system, version 2, non-roller wedge solution
  • Fig. 4 second version design, two-roller wedge solution
  • Fig.5 second version design, one-roller wedge solution.
  • a suspension system consists of base plates 1 fixed to a chassis frame at both ends of a car in the area where wheel sets are located; the base plates are supported by sets of suspension springs 2 mounted on matching saddles 3 .
  • the saddle 3 is seated on a bearing shell (axle box) of a wheel set.
  • In the central part of each base plate 1 there is a space 4 surrounded by surfaces that are mating with saddle columns 5 .
  • friction wedges 6 are applied between the saddle columns 5 and the mating surfaces of base plates 1 , on both sides.
  • Rollers preferably one or two of them, are incorporated in the friction wedges 6 .
  • the surface formed by rollers is inclined at an angle of 30° to the level, and a lining pad 7 of a friction factor lower than 0.2 is applied over the vertical surface of the wedge.
  • this vertical surface forms a sector of a cylinder aligned with a horizontal axis.
  • the vertical surface is inclined towards the wedge slope at an angle of 3°, and a lining pad 8 of a friction factor lower than 0.2 is applied over the surface.
  • a bumper 9 is mounted on the sloped plane next to the roller, on the lower side.
  • a plate 10 divides spring sets 2 , preferably at half height. The plates 10 belonging to each of the two adjoining spring sets 2 are mutually connected.
  • the matching connected plates 7 on both sides of a car are connected through a stabilizing rod 11 .
  • a suspension system consists of base plates 1 fixed to a chassis frame at both ends of a car in the area where wheel sets are located; the base plates are supported by sets of suspension springs 2 mounted on matching saddles 3 .
  • the saddle 3 is seated on a bearing shell (axle box) of a wheel set.
  • In the central part of each base plate 1 there is a space 4 surrounded by surfaces that are mating with columns 5 of the saddle 3 .
  • friction wedges 10 are applied between the saddle columns 5 and the mating surfaces of base plates 1 , on both sides.
  • the top surface of the friction wedge 10 is inclined to the level at an angle of 10° to 40°, preferably 30°, and its vertical surface is inclined towards the wedge slope at an angle of 3°.
  • Lining pads 11 of a friction factor lower than 0.2 are applied over the base plate that is mating the inclined surface of the wedge 10 , and over the surface of the column 5 of the saddle 3 .
  • Spring sets 2 are divided by the plate 10 , preferably at half height.
  • the plates 10 belonging to each of the two adjoining spring sets 2 are mutually connected.
  • the matching connected plates 10 on both sides of a car are connected through a stabilizing rod 12 .
