Protective device against squeezing for rail vehicle

FIELD: transportation.

SUBSTANCE: protective device against squeezing for a rail vehicle with a buffer, the support for which is an energy absorption element connected to the rail vehicle frame. On the energy absorption element, on its end facing away from the vehicle frame, a carrier element is fixed, which on its end projecting in the vertical direction from the buffer supports the protective device against squeezing. A horizontally oriented stop is arranged in such a way that from it the element protecting against squeezing of the protective device in the event of a collision while interacting with the front part of the rail vehicle is installed in the squeezing-protection position extending outwards over the buffer.

EFFECT: increasing the reliability of the protective device.

The invention relates to railway transport, and in particular to methods of manufacturing rod buffer

FIELD: machine engineering.

SUBSTANCE: apparatus comprises a body 1 in the form of a sleeve closed on one side with a bottom 3. The elastomeric shock absorber 2 is partially located in the hub of the housing 1. The elastomeric shock absorber 2 and the support plate 5 are moved relative to the housing 1. On the base plate 5 there are fixed screeds 6 with hooks 8 rotated relative to them. The hooks 8 press the pre-inserted spacers 7 to the protrusions 10 on the hub of the housing to pre-press the elastomeric shock absorber 2. The couplings 6 with the hooks 8 are formed in one piece and are located on a sliding fit on the protrusions 10 of the hub of the housing 1.

EFFECT: simplification of manufacturing technology and increase of reliability of work.

FIELD: construction.

SUBSTANCE: device (1) for preventing rail vehicles (5) from creeping on each other comprises an energy absorbing element (2) extending in the longitudinal direction, hollow inside, which has a fastening side (3) for fastening on a rail vehicle (5), and a shock side (6) facing away from this fastening side (3), and also a flange (7) with a bump surface (11) fixed to the shock side (6) of the energy absorbing element (2). The flange (7) extends beyond the contour of the energy-absorbing element (2) on its shock side (6) in the vertical direction to form a crossarm (8, 9) projecting beyond the energy-absorbing element (2), which at its free end has a vertical stop (10) projecting from the bump surface (11), wherein means are provided for moving the vertical stop (10) under the action of a shock load in the longitudinal direction.

EFFECT: improving the effectiveness of protection against creeping on each other in case of collision of similarly executed, as well as differently executed, rail vehicles.
