Pivoted Head Patents (Class 188/220.1)
  • Patent number: 8360214
    Abstract: The brake shoe support assembly is able to track the lateral movement of a wheel, typically a wheel on an axle truck that allows lateral wheel movement. In operation, a flange of the wheel pushes on one side of the brake shoe support assembly, pushing it along a pin, and compressing a resilient biasing structure. As the wheel returns to a center or neutral position, the compressed resilient biasing structure expands pushing the brake shoe support assembly back to an original or neutral position. The resilient biasing structure also minimizes the lateral movement of the brake shoe support assembly down the wheel taper under normal braking loads thus preventing shoe ride-off. The resilient biasing structure may be enclosed in a housing adapted to prevent the intrusion of contaminants.

  • Patent number: 6732841
    Abstract: A rail vehicle bogie brake has a brake beam (4, 5). Which at its end is provided with a brake block holder (8) having a brake block (9) for brake application against a tread of a wheel. The brake block holder has a transverse cylinder (19) for its pivotable connection with the brake beam. A mounting shaft (14) is attached in the end of the brake beam and is provided with a sleeve (16). The sleeve engages the mounting shaft and has an outer diameter corresponding to the inner diameter of the cylinder. A sleeve plate (17) is held against the sleeve, which is slightly longer than the cylinder, by means of screws (18) attached in the mounting shaft and prestressing the sleeve.

  • Patent number: 6551003
    Abstract: A joint for pivotally joining a brake head to a brake beam of a railway car which allows to the brake head to modify its radial direction with respect to a bogie wheel, allowing the brake shoe to adapt to the wheel contour, and achieving an adequate force distribution along the brake shoe.

  • Patent number: 6176354
    Abstract: A truck mounted rail brake including at least a primary beam having a center section and a pair of end sections with guide end extensions. A brake head is removably mounted to the end sections by a pin. The pin is dimensioned to allow pivotal movement of the brake head about the pin. The pin is retained in the brake head by either a tab or another pin above and transverse to the first pin.
