EP0999111B1 - End stop with a cross stop section acting in the cross direction of a railway vehicle at least in a curved orientation - Google Patents

Abstract

The stop has a transverse stop shaped sector which acts with a cam track on the limiting stop (2) and a support roll (4) to limit the transverse deviation of the wagon box (1) relative to the bogie (3). To limit not only the transverse play between the bogie and the wagon box, but also the rotation of the bogie relative to the wagon box, there is also a shaped sector for this purpose.

Description

The invention relates to a limit stop with an at least at bow position in the transverse direction of a rail vehicle effective Queranschlagsabschnitt.

A limit stop of the generic type is z. B. from DE-44 25 562 C2 known. In this embodiment, the transverse stop for the restriction the cross play between the car body and the bogie of a Rail vehicle on a roll and a contour plate, each one of both are arranged on the other vehicle parts. To a transverse stop too create in which a defined transverse suspension in each arc radius and any Position of roll and contour plate is present to each other and the inelastic Transverse thrust is turned off, the role is on a deflector, consisting lever and plate, stored, the other end of the lever on an elastic Stop abuts. To the stop and the lever only with defined forces load, a fixed end rash for roll or diverter is still provided. The Ausdrehbewegung the bogie with respect to the car body is through this arrangement is not confined safely, so that another rotation limiting stop is to be provided elsewhere.

The invention has for its object a limit stop and an arrangement show that in a compact design, both the limitation of Querspiels between chassis and car body as well as the rotation limit of Chassis against the car body of a rail vehicle allows.

This object is achieved by the limitation stop marked in claim 1 solved.

Advantageous embodiments and modifications of the invention are in the dependent claims 2 to 12 indicated.

The invention is based on an embodiment with reference to a drawing explained in more detail.

A car body 1 has on both sides of the vertical central longitudinal plane depending on a limit stop 2 with a contour track on which the landing gear 3, in particular a bogie, associated support stops, in particular support rollers 4, unroll can. The contour line has one at least at Bogenfahrt or Bogenhalt transversely effective transverse stop contour section 5 and a section for rotation limitation (rotation limiting contour section 6). These two Contour sections are in direct local proximity to each other at a limit stop, thus formed as a combination stop, together arranged.

Of course, it is free, the support rollers 4 the car body 1 and the limit stops 2 to assign the chassis 3, creating a kinematic Reversal of the embodiment is generated.

Which construction method is more expedient arises largely from the boundary conditions the overall design and the requirement for the rail vehicle.

The limit stops 2 are opposite each other in a transverse plane arranged.

To obtain a large support base and a favorable power transmission, the Limit stops 2 and the associated support rollers 4 within the Transverse planes as far away as possible from the vertical central longitudinal plane 7 on Car body 1 and arranged on the chassis 3.

The plane of the contour line of the limit stops 2 is in a vertical plane of the rail vehicle. The contour line has a parallel to the transverse direction extending section, as well as one over a rounded section connected to this, in the direction of the chassis 3 to the vertical center longitudinal planes down angled, sloping section on. This creates a coherent, towards the vehicle end outward open contour line, the suitable is, the support roller 4 from abutment up to a maximum Ausdrehbewegung the Chassis 3 and a maximum allowable transverse displacement form fit to lead. The parallel to the transverse direction extending portion of the contour line essentially the rotation limiting contour section 6 and the angled, oblique section essentially takes into account the angle of rotation Transverse stop contour section 5 represents.

Especially for vehicles with landing gear 3, which is not a centric Vertical axis are designed to be rotatable and their Drehpol limited longitudinally displaceable is executed, as well as in the embodiment, the arrangement of further stops 8 (turn-out stops) required. It is ever a stop 8 on both sides the vertical central longitudinal planes 7 of the car body 1 and the chassis. 3 arranged, which against an associated support member 9, in particular another Support roller 4, the chassis 3 and the car body 1 at maximum permitted Outward rotation of the chassis 3 relative to the car body 1 comes to rest. The limit stops 2 and the stops 8 are arranged such that these form a quadrangle, in particular a rectangle, whose longer sides in Vehicle transverse direction are arranged.

The support rollers 4 and / or support elements 9 and / or the limit stops 2 and / or stops 8 are designed to be adjustable in the longitudinal and / or transverse direction.

The limit stops 2 can furthermore have a second transverse stop contour section have, which is effective even when driving straight ahead in the transverse direction and limited the cross game between car body 1 and chassis 3.

The transverse stop contour sections 5 and / or the second transverse stop contour sections can be elastically formed or supported to an inelastic To avoid cross shock. The same effect can be with elastically supported or trained support rollers 4 or support elements 9 reach.

When bow travel with respect to the curve superelevation too low speed or holding in curves with curves exaggeration prevent the limit stops 2, the transverse displacement between the car body 1 and chassis 3 over a planned, tolerable level.
When bow trips at smaller radii of curvature limiting stops 2 and possibly the stops 8 limit the rotatability of the chassis. 3

Limit stops 2 and / or stops 8 in training and arrangement according to The embodiment are suitable for arc radii from about 500 m in engagement to reach and at a radius of curvature of about 100 m, which is a rotation of the Chassis 3 of about 6 ° corresponds to the Andrehbewegung and Querauslenkung of Chassis relative to the car body 1 to inhibit. Due to changed education and / or arrangement of limit stops 2 and / or possibly stops 8 are also other maximum Ausdrehwinkel and bow radii limited.
