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 a rotatable eccentric horizontal and vertical adjustment of the wheel axis with respect to the frame are.
- 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 Articulation bearing surfaces 4 rotatable and pivotable in the direction of arrow 5.
- 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.
