Abstract

A railway bogie includes one or more operative components for the operation of the railway bogie and an impact guard protecting the one or more operative components from flying debris. The impact guard is made of a high density polyethylene (HDPE). The railway bogie can be used in Jacobs bogies of multiple units operating under wintery conditions.

First claim

What is claimed is:

1. A railway bogie, comprising:
one or more operative components for the operation of the railway bogie; and
a first impact guard and a second impact guard protecting the one or more operative components from flying debris under wintery conditions, wherein each of the first and second impact guards comprises a plurality of fastening holes and each of the plurality of first and second impact guards is fastened to one of the end beams via the holders or brackets using bolts, washers and nuts and the fastening holes,
wherein the impact guard is made of a high density polyethylene (HDPE),
the impact guard is a solid milled slat,
the impact guard includes a base and at least one stiffening ridge extending at a substantially right angle from the periphery (P) of the base,
the railway bogie includes a bogie frame with two side beams and two end beams extending between the side beams, and
the impact guard is fastened to one of the end beams.

2. The railway bogie according to claim 1 , wherein the impact guard has an L-shaped, U-shaped or rectangular cross-section.

3. The railway bogie according to claim 1 , wherein the impact guard is made of one piece and extends substantially across the entire width of the bogie.

4. The railway bogie according to claim 1 , wherein the impact guard is black.

5. The railway bogie according to claim 1 , wherein the impact guard includes at least one cut-out adapted to receive a bogie component.

6. The railway bogie according to claim 1 , wherein the impact guard is fastened to the underside of the end beam.

7. The railway bogie according to claim 1 , wherein said one or more operative components are one or more cables or fluid pipes, which are covered by the impact guard.

8. The railway bogie according to claim 7 , wherein said one or more operative components are air brake piping.

9. The railway bogie according to claim 1 , the railway bogie being a traction bogie or a trailer bogie.

10. The railway bogie according to claim 9 , the railway bogie being a Jacobs traction bogie or a Jacobs trailer bogie.

11. A diesel or electric multiple unit comprising at least one railway bogie according to claim 1 .

12. The railway bogie according to claim 1 , further comprising at least one third impact guard, wherein the third impact guard is a solid milled slat made of HDPE having a rectangular cross-section and a substantially cuboid shape, wherein the third impact guard comprises a curved cut-out through which a pipe or a cable is received.

13. A railway bogie comprising:
one or more operative components for the operation of the railway bogie; and
a plurality of first impact guards and a plurality of second impact guards, said first and second impact guards configured to protect the one or more operative components from flying debris under wintery conditions,
wherein the first and second impact guards are made of a high density polyethylene (HDPE),
each of the first and second impact guards is a solid milled slat,
each of the first impact guards comprises:
a base, and
a single stiffening ridge extending at a substantially right angle from the periphery of the base at a side of the first impact guard,
each of the second impact guards comprises:
a base, and
at least two stiffening ridges extending at a substantially right angle from the periphery of the base, with a stiffening ridge at each of opposite sides of the second impact guard
the railway bogie includes a bogie frame with two side beams and two end beams extending between the side beams,
the one or more operative components comprise an air brake running along one of the end beans, and at least some of the first impact guards are configured to protect said air brake pipe,
at least some of the first impact guards extend substantially across an entire width of the bogie frame, and
each of the plurality of first and second impact guards is fastened to one of the end beams via holders or brackets.

14. The railway bogie according to claim 13 , wherein each of the first and second impact guards comprises a plurality of fastening holes and each of the plurality of first and second impact guards is fastened to one of the end beams via the holders or brackets using bolts, washers and nuts and the fastening holed.

15. The railway bogie according to claim 13 , further comprising at least one third impact guard, wherein the third impact guard is a solid milled slat made of HDPE having a rectangular cross-section and a substantially cuboid shape, wherein the third impact guard comprises a curved cut-out through which a pipe or a cable is received.

16. The railway bogie according to claim 1 , wherein the impact guard is made of ultra-high-molecular-weight polyethylene (UHMW-PE).
