Abstract
A corrective device for correcting uneven brake shoe wear on a brake mechanism for a railway vehicle, wherein the railway vehicle includes a brake beam having a tension beam coupled to a compression beam, a brake head with brake shoes provided at each end of the brake beams, and a slack adjuster. The corrective device is configured to cooperate with at least one of the compression beam and the slack adjuster to minimize or prevent the compression beam and the tension beam from rotating relative to the wheels and side frames of the railway vehicle. A braking system including the corrective device and a method for correcting uneven brake shoe wear on a brake mechanism for a railway vehicle is also provided.

A corrective device for correcting uneven brake shoe wear on a brake mechanism for a railway vehicle, the railway vehicle including a brake beam having a tension beam coupled to a compression beam, a brake head with brake shoes provided at each end of the brake beam for cooperating with wheels of the railway vehicle, and a slack adjuster, and wherein the corrective device is configured to cooperate with at least one of the compression beam and the slack adjuster to minimize or prevent the compression beam and the tension beam from rotating relative to the wheels of the railway vehicle.
A braking system for a railway vehicle comprising:
- a brake beam including a tension beam coupled to a compression beam;
- a brake head with brake shoes provided at each end of the brake beam, the brake shoes configured for cooperating with wheels of the railway vehicle;
- a slack adjuster associated with the brake beam;
- and
- a corrective device configured to cooperate with at least one of the compression beam and the slack adjuster to minimize or prevent the compression beam and the tension beam from rotating relative to the wheels of the railway vehicle.
A method for correcting uneven brake shoe wear on a brake mechanism for a railway vehicle, the railway vehicle including a brake beam having a tension beam coupled to a compression beam, a brake head with brake shoes provided at each end of the brake beams, wherein the brake shoes are configured to cooperate with wheels on the railway vehicle during a braking operation, and a slack adjuster, and wherein the method includes providing a corrective device and associating the corrective device with at least one of the compression beam and the slack adjuster to minimize or prevent the compression beam and the tension beam from rotating relative to the wheels of the railway vehicle.
