Definitions

  • the invention relates to a rail wheel consisting of a wheel body and wheel tires with rubber-elastic elements which lie on both sides of the wheel center plane in overlapping bearing surfaces of the wheel body and of the wheel tire and are under prestress between the contact surfaces and limit the axial and radial movement between the wheel tire and wheel body.
  • the rubber-elastic elements are subjected to pressure in the rail area in the event of an axle load, while the rubber-elastic elements are relieved in the zenith area.
  • another known rail wheel (DE 33 28 321 B) with overlapping parts lying parallel to one another and parallel to the wheel plane, which are connected by intermediate rubber washers, the rubber washers are only subjected to thrust under axle load.
  • an overlap which has approximately V-shaped annular spaces for the rubber washers or a number of rubber bodies distributed on the corresponding pitch circles on both sides of the wheel plane, deflection of the rail wheel under load leads to a shear load and to a compression of the rubber bodies.
  • the V-shape can be formed by two separate, correspondingly arranged conical rubber washers on both sides of the wheel plane, rows of rubber bodies arranged obliquely to each other or by a total of V-shaped rubber rings or V-shaped rubber bodies.
  • the object of the invention is to further refine the generic rubber-sprung rail wheels with regard to the driving comfort they offer, and also to improve the sound radiation behavior in the sense of minimizing noise in the rail-wheel contact area.
  • This object is achieved in that the surface normals of the contact surfaces with a component are directed to the wheel axle in such a way that under an axle load the rubber-elastic elements in the zenith area of the rail wheel are compressed beyond the preload and are relieved in the rail area of the rail wheel.
  • the deflection behavior is opposite to that of conventional rail wheels.
  • the rubber-elastic elements are somewhat relaxed under axle load and therefore relatively soft, so that the rail wheel has a new, less radiation-producing behavior and less screeching noises when cornering.
  • the axially soft wheel-rail contact area can also better absorb side impacts, which improves driving comfort.
  • the "hanging" rail wheel according to the invention leaves it with more degrees of flexibility. The vibration excitation is reduced.
  • the principle of the solution according to the invention can be realized in that the contact surfaces of one annular space are mirror images of those of the other annular space with respect to the wheel center plane and have the shape of truncated cones.
  • the term "truncated cone jacket” is also understood to mean a jacket with a generatrix that is not straight but curved. In any case, an embodiment is conceivable in which the imaginary tips of the truncated cone shells are directed away from or towards one another.
  • the contact surfaces assigned to the same annular space are preferably parallel to one another.
  • the generatrices of the truncated cone shells can lie on the parallels of an outer and an inner rhombus, one diagonal of which coincides with the wheel axis and is shorter than the other.
  • an outer contact surface of the contact surfaces should be formed on a ring that can be attached to the wheel body or tire.
  • a further axial annular space can be provided between the wheel body and the wheel tire, in which a radially acting elastic stop with radial play is located.
  • 1 is a rail wheel with a one-piece wheel tire in axial cross section
  • 2 shows a rail wheel in an embodiment modified from FIG. 1 in the axial half cross section
  • FIG. 3 shows a rail wheel with a two-part wheel tire in axial cross section
  • FIG. 4 shows the rail wheel according to FIG. 1 in axial cross section with diamonds lying one inside the other as geometric locations for contact surfaces for rubber-elastic elements
  • FIG. 5 shows a rail wheel with an embodiment modified from FIG. 1 in the axial half cross section
  • FIG. 6 shows a rail wheel in a further embodiment modified from FIG. 1 in the axial half cross section
  • Fig. 7 is a rail wheel in a modified version of FIG. 6 in the axial half cross section and
  • Fig. 8 is a rail wheel in a modified version of FIGS. 1-7 in the axial half cross section.
  • the rail wheel shown in FIG. 1 consists of a wheel body 1 and a one-piece wheel tire 2 as well as rubber-elastic elements 3 inserted between wheel body 1 and wheel tire 2 under pretension.
  • the wheel body 1 further comprises a rim 6 with a rim shoulder 7 and a rim shoulder 8 designed as a ring which can be screwed onto the rim 6 by means of bolts 9.
  • the rim shoulders 7, 8 form between there is a groove 10 in which two hard rubber rings form an inner elastic stop 11 at maximum deflection.
  • the wheel tire 2 has an annular web 12 with a dovetail cross section on the inside. This web 12 overlaps with the rim shoulders 7, 8 in the radial direction.
  • the rubber-elastic elements 3 lie on both sides of the wheel center plane 13 in annular spaces which are delimited by contact surfaces 15, 16 and contact surfaces 7a, 8a of the rim shoulders 7, 8 formed on the web 12.
  • the contact surfaces 7a, 8a, 15, 16 lie on the mantles of truncated cones, the generatrices of which also form the parallels of an outer and inner rhombus with corner points A, B, C, D or E, F, G, H have.
  • the position of the paired contact surfaces 7a, 15 and 8a, 16 is a mirror image of the wheel center plane 13. Their inclination is determined by the fact that the diagonal coinciding with the wheel axis 5 is smaller with the corner points B-D and F-H The axial and radial stiffness of the wheel can be determined as the other diagonal with the corner points A - C and E - G. via the inclination of the contact surfaces 7a, 8a, 15, 16.
  • Fig. 2 differs from that of Fig. 1 in that the contact surfaces 7a, 8a, 15, 16 have no straight generatrix, but curved generatrix, i.e. are crowned.
  • FIG. 3 differs from that of FIG. 1 only in that the wheel tire 2 consists of inner and outer rings 19, 20 shrunk onto one another.
  • the embodiment of FIG. 5 differs from the embodiments of FIGS. 1-4 primarily in that a groove 14 formed between annular shoulders 21, 22 is located on the inner edge of the wheel tire and a web 23 overlapping with the annular shoulders 21, 22 on the wheel body 1 is trained.
  • the corresponding contact surfaces 7a *, 8a *, 15 *, 16 * are the reverse of those of the exemplary embodiments in FIGS. 1-4.
  • FIGS. 6 and 7 differ from that of FIG. 1 in that several similar annular spaces with prestressed rubber-elastic elements are arranged one behind the other in the radial direction. With this configuration, a small axial width of the wheel with improved radial and axial spring properties is achieved.
  • FIG. 8 differs from all of the foregoing primarily in that the contact surfaces 7a **, 8a **, 15 **, 16 ** for the rubber-elastic elements 3 * are not inclined to the wheel axis 5, but rather parallel or lie vertically. Despite this other geometrical design, the principle of the invention is also observed here that the normals of the coaxial contact surfaces 7a **, 8a **, 15 **, 16 ** are directed towards the wheel axle 5, such that the rubber-elastic elements 3 are applied when the axle is under load * In the zenith area Z, additional pressure loads and in the rail area S, pressure relief.

Abstract

La présente invention concerne une roue élastique caoutchoutée pour véhicules sur rails. Elle se compose du corps de roue (1), du pneu (2) et d'éléments élastiques caoutchoutés (3) logés sous précontrainte dans des espaces annulaires ménagés entre le corps de roue (1) et le pneu (2). Ces espaces annulaires sont délimités par des surfaces d'application (7a, 8a, 15, 16) pour les éléments élastiques (3) qui sont orientées de telle façon que, sous la charge de l'essieu, les éléments élastiques (3) sont comprimés au-delà de la précontrainte dans la zone zénithale (Z) de la roue et soulagés dans la zone rail (S) de la roue.
