Abstract

Each fitted so as to lean forward towards buffers (4), protective shields (1) have a 70[deg] angle of forward lean towards a chassis (2) and a 90[deg] angle towards an over-buffering buffer. They also trace a semi-circle by following the end (6) of a tank (7) turned towards them and fit with a clearance form it. On their bottom edges (8), they link as well to the chassis.

Description

The invention relates to a buffering protection for rail vehicles, especially tank or tank cars, each with a chassis provided with a chassis, which has buffers on its front sides and on which a tank is arranged, whose end faces are shielded in each case by a protective shield against shocks in an over-buffering.

In railway operation it happens that due to high run-up speeds rail vehicles over-bump (ascend), ie, a front or rear standing vehicle slips due to the impact energy on the affected vehicle. Consequently For example, the buffers may damage the tank of an affected vehicle and dangerous cargo may leak or the cargo may be damaged. The purpose of over-buffering protection is to protect the tank and the load.

From the DE 8705085 is a buffering protection is known, in which a vertically arranged attached to the lower metal plate is designed as a ram.

From the DE 196 26 496 Furthermore, a buffering protection is known, which is fastened on both ends frontally in front of the tank on the underframe and which is formed obliquely inclined in the direction of the tank.

Both overbuffer protection devices have in common that when hitting the buffers of an ascending railroad car they impinge obliquely on the overbuffer protection in such a way that the buffers slide off the overbuffer protection devices and the ascending car experiences an additional acceleration upwards, whereby the damage caused by the overbuffering be reinforced on the affected vehicle.

Object of the present invention is therefore to provide a Überpufferungsschutz of the aforementioned type, which completely absorbs the impact energy of an ascending vehicle through the buffer and thus ensures that the located behind the Überpufferungsschutz outer skin of the tank is completely secured against shock.

This object is achieved in that the shields are each disposed in the direction of the buffers vorgeneigt.

The pretilt of the shields has the advantage that the bumpers of the ascending vehicle impinge substantially perpendicular to the shields, ie, to introduce their entire impact energy into the shields, without causing damage to the affected vehicle, which can lead to damage to the tank and hazardous cargo may cause significant environmental damage or fire or explosion hazard.

Particularly advantageously, an inclination of the shields of about 70 ° relative to the base has been found, as a result of the arrangement adjacent to the tank and standardized distances of buffers, pivots, axes and return of the tank to the base an impact angle ascending buffer of approximately 90 ° results.

Further details of the invention will become apparent from the following detailed description and the accompanying drawings, in which a preferred embodiment of the invention is illustrated, for example.

A buffering protection consists essentially of a protective shield 1, which is fixedly connected to a chassis 2 provided with a chassis, which has at its end faces 3 buffers 4, wherein the shields 1 are each disposed in the direction of the buffers 4 vorgeneigt. The propensity 5 is opposite the base 2 preferably at an angle of 70 °. The protective shields 1 are the semi-circular and spaced from the end 6 of the respective end facing 6 of the tank 7 following. The shields 1 are connected at their lower sides 8 to the undercarriage 2. They are connected at their the ends 6 of the tank 7 opposite sides via support struts 9 with the base, preferably welded. At their upper sides facing away from their undersides 8 10, the shields 1 are provided with tubular Verstärkungswulsten.

The shields 1 are preferably arranged adjacent to the ends 6 of the tank 7 in such a way that they are located in the region of a tank-side railing 12 of the undercarriage 2 arranged transition stage 13, and thereby cause no obstruction of a user of the transition stage 13, since the shields with their upper edge 10 or the reinforcing beads 11 do not protrude from a plane which is spanned by the tank-side railing 12.

In the event that an adjacent vehicle rises and its buffers arranged on a frame 14 15 hit the shield 1, in cooperation with the effect of the buffer 15 and the deformation resistance of the protective shield 1, the impact energy of the impinging adjacent vehicle can be so completely degraded, that the tank 7 is completely secured against contact and damage.
