Abstract

A compressible filler piece for a brake calliper of a railway vehicle is adapted to at least partially fill out a space needed by a component ( 409 ) of the brake calliper for its operation. The filler piece can be applied to the protection of wheel brakes of low floor passenger trains against ice and snow.

First claim

What is claimed is:

1. A brake caliper for a railway vehicle comprising:
at least one compressible slice-shaped filler piece adapted to at least partially fill out a space provided for a component of the brake caliper for its operation;
a bridge piece with a fastening member for fastening the brake caliper to the railway vehicle;
a brake lever arrangement having two brake levers pivotably joined to the bridge piece; and
a brake cylinder arranged between respective ends of the brake levers and adapted to actuate the brake levers,
wherein the at least one compressible slice-shaped filler piece is arranged between one of the brake levers and the fastening member and/or the at least one compressible slice-shaped filler piece is arranged between one of the brake levers and the brake cylinder.

2. The brake caliper of claim 1 , wherein the filler piece comprises a compressible core.

3. The brake caliper of claim 2 , wherein the compressible core is waterproof.

4. The brake caliper of claim 2 , wherein the core comprises foam.

5. The brake caliper of claim 4 , wherein the foam is polyethylene foam or polyurethane foam.

6. The brake caliper of claim 1 , wherein the filler piece comprises a protective cover.

7. The brake caliper of claim 6 , the protective cover comprising polyethylene or polyamide.

8. The brake caliper of claim 6 , wherein the protective cover has at least one clearance allowing the compression of the filler piece.

9. The brake caliper of claim 6 , wherein the protective cover includes two different plates.

10. The brake caliper of claim 1 , wherein the filler piece comprises at least one filler piece fixing device for fixing the filler piece to the brake caliper.

11. The brake caliper of claim 10 , wherein the filler piece fixing device comprises:
a) a hole formed in the filler piece for receiving a fastener; and/or
b) a cut-out and an associated eyelet both formed in the filler piece for receiving a fastener.

12. The brake caliper of claim 1 , wherein the filler piece is made of at least two mounting parts, the filler piece being adapted to be disassembled into said mounting parts to facilitate its fastening to the brake caliper.

13. The brake caliper of claim 1 , wherein the filler piece comprises a seat for accommodating a brake cylinder bellows.

14. The brake caliper of claim 13 , said seat having a curved wall.

15. The brake caliper of claim 14 , said curved wall being a circular or a circular arc shaped wall.

16. A method for protecting a brake caliper of a railway vehicle against ice or snow comprising:
providing the at least one compressible slice-shaped filler piece according to claim 1 .

17. A brake caliper for a railway vehicle comprising
at least one compressible slice-shaped filler piece adapted to at least partially fill out a space provided for a component of the brake caliper for its operation;
a bridge piece with a fastening member for fastening the brake caliper to the railway vehicle;
a brake lever arrangement having two brake levers pivotably joined to the bridge piece; and
a brake cylinder arranged between respective ends of the brake levers and adapted to actuate the brake levers,
wherein the at least one compressible slice-shaped filler piece is arranged between one of the brake levers and the fastening member.
