Definitions

  • the invention relates to a wheel axle for rail vehicles according to the preamble of Main claim.
  • Wheel axles mounted in this way are used for various rail vehicles such as Locomotives, wagons, etc. are used in pairs on springs in a bogie used or attached to the wagon frame in simpler versions.
  • the object of the invention is to provide a wheel axle for rail vehicles of the type mentioned Art to create, with simple means both a horizontal and a vertical adjustment is possible.
  • the object is achieved in that the spherical bearing rings as rotatable Eccentric also for vertical adjustment of the wheel axle are provided opposite the frame with which an inclination movement of the vehicle is generated.
  • the area of the wheel bearing spring on one side of the Viewed wheel axis - at a single point both a steering movement in a horizontal as well as a slope in the vertical direction.
  • the Eccentric can be turned from its rest position.
  • each axis can be one Bogie can be adjusted on both sides and thus receives an optimized barrel geometry Cornering.
  • the eccentric can directly support the outer ring raceway of the rolling bearing or one commercially available rolling bearings can be used in it.
  • one commercially available rolling bearings can be used in it.
  • the eccentric from lighter material, for example cast aluminum, and a Weight-optimized design through recesses, struts, etc. to be provided.
  • the invention is based on the example shown in the drawing described.
  • the bearing housing 1 is provided with support brackets 2, as here not shown, about springs with a frame, e.g. B. connected to a bogie are. Inside the bearing housing 1 is an eccentric 3 over part-spherical Spherical bearing surfaces 4 in the arrow direction 5 rotatably and pivotably arranged.
  • a roller bearing 6 indicated by two circles, for example a commercially available one Cylindrical roller bearing is at a distance from the center line 7 of the spherical bearing in the eccentric 3 used and rotatably supports one side of the wheel axle.
  • the invisible other side the wheel axle 8 is identical.
  • FIGS. 2 and 3 show the rest position O according to FIG. 1 again.
  • the frame frame takes along attached wheels 11 the smallest height and is aligned horizontally. This corresponds to driving straight ahead on a horizontally aligned pair of rails.
  • figure 4 shows the positions of two wheel axles 8 arranged on a bogie, which are set for cornering on an inclined pair of rails.
  • the right one Eccentric 3 of the upper wheel axle 8 is adjusted to position H, which is shown in FIG. 1 is drawn.
  • the right eccentric 3 of the lower wheel axle 8 takes the Position V according to Figure 1.
  • the eccentric 3 shown on the left are unchanged in the Position O.
  • a single wheel axle 8 is shown in FIG. 5, but not in the horizontal direction is adjusted and a maximum by adjusting the left eccentric in position U. Inclination of the frame 9 causes.
  • the right eccentric 3 is in position O. Um, however to avoid a steering adjustment of the wheel axis 8 in the horizontal direction during the actuating process from the rest position shown in Figure 2 initially both Eccentric 3 are brought in the same direction from the rest position O to the H position. After that the left eccentric 3 is placed from H to U and the right eccentric 3 in opposite directions but brought back to the rest position O synchronous to the left eccentric 3.
