Abstract
An apparatus includes a frame, a braking material and a guide material. The frame includes a braking portion and a guide portion. The braking portion extends generally circumferentially around a surface of a wheel. The guide portion is coupled to the braking portion. A first part of the guide portion extends from the braking portion proximate to a first end of the braking portion over a portion of the wheel. The braking material is coupled to the braking portion of the frame. The braking material provides frictional force opposing rotational movement of a wheel when a force is applied between the braking material and the wheel. The guide material is couple to the guide portion of the frame. The guide material is coupled to the guide portion of the frame.
Claims20
An apparatus, comprising:
- a frame comprising:
- a braking portion extending generally circumferentially around a surface of a wheel;
- a guide portion coupled to the braking portion, wherein a first part of the guide portion extends from the braking portion proximate to a first end of the braking portion over a portion of the wheel;
- a braking material coupled to the braking portion of the frame, the braking material configured to provide frictional force opposing rotational movement of the wheel when a force is applied between the braking material and the wheel;
- and
- a guide material coupled to the guide portion of the frame.
An apparatus comprising:
- a brake beam comprising a first receiver at a first end of the brake beam and a second receiver at a second end of the brake beam;
- a first braking component and a second braking component, each of the first and second braking components comprising:
- a frame, comprising:
- a braking portion generally circumferentially around a surface of a wheel;
- a guide portion coupled to the braking portion, wherein a first part of the guide portion extends from the braking portion proximate to a first end of the braking portion over a portion of the wheel;
- a braking material coupled to the braking portion of the frame, the braking material configured to provide frictional force opposing rotational movement of a wheel when a force is applied between the high friction material and the wheel;
- and
- a guide material coupled to the guide portion of the frame;
- wherein the first braking component is coupled to the first end of the brake beam at the first receiver of the brake beam and the second braking component is coupled to the second end of the brake beam at the second receiver of the brake beam;
- wherein the brake beam is disposed adjacent to a first wheel and a second wheel and is configured to apply frictional force to the first wheel by the high friction material of the first braking component and to the second wheel by high friction material of the second braking component.
A method, comprising:
- providing a brake beam comprising a first receiver at a first end of the brake beam and a second receiver at a second end of the brake beam;
- providing a first braking component and a second braking component, each of the first and second braking components comprising:
- a frame, comprising:
- a braking portion extending generally circumferentially around a surface of a wheel;
- a guide portion coupled to the braking portion, wherein a first part of the guide portion extends from the braking portion proximate to a first end of the braking portion over a portion of the wheel;
- a braking material coupled to braking portion of the frame, the braking material configured to provide frictional force opposing rotational movement of a wheel when a force is applied between the high friction material and the wheel;
- and
- a guide material coupled to the guide portion of the frame;
- wherein the first braking component is coupled to the first end of the brake beam at the first receiver of the brake beam and the second braking component is coupled to the second end of the brake beam at the second receiver of the brake beam;
- disposing the brake beam adjacent to a first and a second wheel;
- applying frictional force to the first wheel by the braking material of the first braking component and to the second wheel by braking material of the second braking component.
