Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a resilient pivoting device for a central shock coupler for a rail vehicle, which connects a casing fixed to the vehicle and the same at equal distances from the casing. a connecting rod protruding into the casing, and between the casing and the connecting rod there is disposed one or more rings made of rubber or silastic, which are preloaded in the vertical direction and arranged along the connecting axis. the connecting rod and the casing inner part have annular projections extending towards each other, the casing inner part and the connecting rod have an elliptical cross-section, and the ring has annular projections extending towards each other; Concerning things in a preserved form.

BACKGROUND OF THE INVENTION In the elastic pivoting device disclosed in German Patent Application No. 2701984 1', the pivoting movement of the connecting rod in the horizontal direction pivots the gauging to the vehicle via a pin extending in the vertical direction. Whereas vertical pivoting movements and rotational movements about the coupling axis are achieved by elastically supporting the coupling rod with a defined return force.

This resilient pivot system using a plurality of resilient rings is extremely effective under various operating conditions in the range of use for heavy rail vehicles. Light and compact rail vehicles usually do not provide the necessary installation depth and installation height for journal bearings. Therefore, taking into account a given installation height, the housing is fixed to the motor vehicle and, in order to reduce the installation depth, no ring is provided as an elastic member. In this case, the pulling and pressing forces are indeed absorbed by this one ring, but by arranging the maximum cross section of the tension bar horizontally), a return force in the horizontal direction is no longer obtainable.・.

SUMMARY OF THE INVENTION It is therefore an object of the invention to improve an elastic pivoting device of the type mentioned at the outset, which has small constructional dimensions and is fixed in position by the housing during pivoting movements in the vertical direction and in connection. It is an object of the present invention to provide an elastic pivoting device that not only always provides a return force during rotational movement about an axis, but also provides a predetermined return force in the horizontal direction.

In order to solve this problem, the present invention provides that the long axis of the oval cross-section of the inner housing part and the connecting rod runs vertically in the installation position.

Functions and Effects of the Invention If, as in the present invention, the long axes of the elliptical cross sections of the inner part of the casing and the connecting rod extend in the vertical direction at the assembled position, a predetermined return force can be generated in the horizontal direction. .

The exemplary casing 1 is fixed to a vehicle (not shown) and surrounds a connecting rod 2 connected to a connecting spatula F.

Both the connecting rod 2 and the inner part of the housing l have an oval cross-section with a vertically long axis in the installed position. While the connecting rod 2 is provided with annular protrusions 4 and 5, the protrusions 4 and 5 are provided inside the casing 1.
A groove 6 is provided correspondingly located to the connecting rod section delimited by 5, and between this groove 6 and said connecting rod section an elastic ring 3 is arranged. The 114 parts 7 of the annular protrusions 4 and 5 and the shoulder part 8 of the groove 6 are connected to the casing 1
is inclined with respect to the vertical axis of The connecting rod 2 is arranged at a predetermined spacing relative to the casing I by means of a rubber or silastic ring arranged perpendicularly to the connecting axis and preloaded between the shoulders 7 and 8. It is maintained at In this case, in order to simplify the assembly and to be able to adjust the preload, the casing 1 consists of two mirror-image half-shells which are releasably connected to each other by means of a screw bolt 9 and a ring. 3 has a slit on one or both sides.

For example, when a pressing force is applied to the connecting rod 2 as shown in FIG. 2, the ring 3 begins to roll according to the rolling contour determined by the shape of the shoulder and a predetermined preload to absorb the impact. Absorb elastically. As the load in the axial direction increases, the ring 3 deforms further, giving it an increasingly spring-elastic property. The coupling also exhibits suitable properties when subjected to tensile loads. Pivoting movements of the coupler in the vertical or horizontal direction are elastically absorbed by the deformation of the ring 3. By selecting the oval cross-section of the connecting rod 2 and the inner part of the housing l, different return forces are produced for the pivoting movement of the connecting rod 2 from its axial rest position. A large return force and thus a large stiffness of the pivoting device is produced by a displacement in a plane containing the long axis of the elliptical cross section. In order to achieve an elastic deformation with an increasing characteristic line and a predetermined restoring force over the entire necessary horizontal pivot range on both sides of the coupler, the plane along which the short axis of the elliptical cross section lies is horizontal. It is located in The movement of the coupling in the vertical direction and the rotational movement about the coupling axis as well as the predetermined return force are always present in this coupling within the framework of the operating conditions.

When used in a heavy vehicle with a specific installation depth, this elastic pivoting device can have a position-fixed casing and two or more rings: 3,
In this case, the number of protrusions 1, 5 and grooves 6 should be increased accordingly.
