Description

SUMMARY OF THE INVENTION The present invention provides a device for steering wheel axle bearing arrangement on a running frame.

The hitherto known axle bearing arrangement compensates for longitudinal and lateral forces and the resulting displacements by means of elastic members built in between the running frame and the axle bearing most often solved by means of rubber-metal elements.

Otherwise, it relies on the transverse stiffness of the vertical suspension of the axle bearing.

The resilient members, especially the rubber-metal elements, have a limited durability and are supplemented with cataracts for increased stiffness as needed.

The above-mentioned drawbacks are eliminated by the device for steering arrangement of the axle bearing of the wheelset on the running frame. The axle bearing consists of a bearing housing in which the axle of the wheelset is mounted in a tilting bearing. The bearing housing has a convex radial surface formed in its upper part, which adjoins the running frame from below, where a concave radial surface is formed, bounded by stops. The height of the stops exceeds the edges of the convex radial surface. The centers of the radiuses of the surfaces of the convex radial surface lie below the center of rotation of the wheelset. The surface radii of the convex radial surface are smaller than the surface radii of the concave radial surface.

By providing a convex radial surface on the upper axle of the axle bearing adjoining the running frame from below, where the concave radial surface is formed, the centers of the radii of the convex radial surfaces are lower than the wheelset centering radius and The axle bearing arrangement of the wheelset on the running frame with optional transverse and longitudinal characteristics was created, which is given by the mutual ratio and size of the radiuses of the surfaces of both surfaces.

Exemplary embodiments are shown in the accompanying drawing in an overall view.

Axle bearing X consists primarily of a bearing housing χχ. The upper portion 1t is provided with a convex radial surface 12. A concave radial surface 21 is formed on the running frame 8 from below, bounded by stops 22 to which the convex radial surface 12 abuts. The centers of the radii of the surfaces of the convex radial surface 12 lie below the center of rotation of the wheelset 2 ^{and the} radii of the surfaces of the convex radial surface 12 are smaller than the radii of the surfaces of the concave radial surface 21. The stop height 22 exceeds the edges 13 of the convex radial surface 12.

The device according to the invention makes it possible to drive the traction under the influence of a longitudinal force exerted e.g. in the case of axellation or lateral force, e.g. arc ride. The deflection of the wheelset 2 resulting from the rolling of the radial surfaces 1, 21 in succession exerts an additional force against the deflection of the wheelset 1, whereby the wheelset 2 ^{and the} parts connected thereto are stabilized against the running frame 2.
