DE102008048247B3 - Anti-climbing device for buffers at locomotives for absorption of impacts as accident buffer, has carrier element adjustably arranged as delimitation element above buffers at locomotive framework over guides - Google Patents

Abstract

The anti-climbing device has a carrier element (6) adjustably arranged as delimitation element above the buffers at a locomotive framework (1) over guides (7). The carrier element is extended in a final area of a flexible buffer way of buffer plates (3), and an end lateral back support (8) is arranged to the carrier element of a firm structure of a striking vehicle (9).

Description

The This invention relates to anti-climb protection for buffers on locomotives to absorb shocks as a crash buffer, wherein an outboard Buffer plate to absorb shock via a Buffer tube with a damping element resiliently arranged piston-like manner in a fixed receiving tube is.

buffer This type are known with different suspension structures and are used on locomotives on the front side. In practice has been shown to be difficult exist if in a locomotive or a locomotive composite a so-called crash occurs. It has been shown that in the meeting the buffer of locomotives may experience a climbing movement being by the sliding steel on steel and a lubricated surface a gliding of the surfaces and thus a Aufkletterbewegung the locomotives is favored.

The The object of the invention is, with simple means a climbing protection to create a leadership the occurring buffer plate ensures and thus protection allows.

The solution This object is achieved according to the invention in that a carrier element as a limiting element above the buffer on the locomotive frame via guides is arranged displaceably and the support element is up in one End region of an elastic buffer path of the buffer plate extends and an end-side abutment of the carrier element of a solid structure associated with an incident vehicle.

hereby will be released shortly after the crash buffer reaches that the support elements above the buffer of an impinging vehicle are located. By the impact the solid structure on the support elements they deviate almost without resistance led on the locomotive frame, whereby the impacting buffers over the entire working path of the crash buffer kept in contact with them and a controlled consumption of energy is made possible.

A advantageous training is created by each Buffer a support element is assigned by cross member connected to a frame and in the form of a drawer in the event of a crash is displaceable by the structure of the occurring vehicle.

Further It is suggested that the Carrier elements over a releasable Limitation on locomotive frame are held in a starting position.

to better load distribution is provided that enlarged end abutment the support elements as contact surfaces for the incident vehicle are arranged.

Farther It is suggested that the end abutment have a broken ribbed bearing surface.

In the drawing is an embodiment of Invention shown schematically. Show it

1 a schematic representation of the arrangement at collision start,

2 a perspective top view of an arrangement,

3 a plan view according to 2 and

4 to 9 a sequence of a collision process with collision of the buffer plates, termination of the elastic buffer path, beginning of a Aufkletterphase, contact of the abutment with the vehicle impact, the end of the first crash stage, the end of the second crash stage.

In the arrangement shown is a locomotive frame 1 with a crash buffer 2 provided, with an external buffer plate 3 for impact absorption via a buffer tube 4 with a damping element resiliently in a fixed receiving tube 5 is arranged. Above the buffer 2 is in each case a carrier element 6 on the locomotive frame 1 about guides 7 slidably disposed, extending into an end region of an elastic buffer path of the buffer plates 3 extend. The carrier elements 6 have an end-side counter bearing 8th that is a solid structure of an impacting vehicle 9 assigned. The counter-bearings 8th are due to enlarged contact surfaces for the impact of the vehicle 9 formed and formed by interrupted ribbed bearing surfaces.

In this case, the carrier elements 6 by appropriate cross member 10 and 11 connected to a frame, so that it in the form of a drawer in the event of a crash by the structure of the vehicle occurring 9 are displaceable.

In the initial position are the support elements 6 via a not shown releasable limitation on the locomotive frame 1 held in an initial position, which occurs when hitting the structure of an impinging vehicle 9 almost without resistance in the locomotive frame 1 dodging.

Already after triggering the crash buffer 3 . 4 protrude the support elements 6 over a buffer plate 12 of the occurring vehicle 9 , If the vehicle 9 begins to climb up, the puff lay down ferteller 12 from below to the support elements 6 and can not move up. The buffer plates 12 thus keep with the buffer plates 3 over the entire working path of the crash buffer 4 Contact and allow a controlled energy consumption.
