Abstract
A single-cylinder, truck-mounted brake assembly for a railway car truck in which low-cost, light-weight, truss-type brake beams are employed, with one beam having an expansible brake actuator in the form of an air bag mounted thereon. The brake rigging arrangement employs an equalizing lever that is pivotally-connected to each brake beam at its centrally-located strut bar, and force-transmitting members between the respective ends of the equalizing levers, so that the force of the brake actuator is transferred from the brake beam strut bar to the brake shoes via the beam tension member. Accordingly, the light-weight, low-cost brake beams are not subjected to such bending forces as would otherwise require a stronger beam. The single-cylinder air bag arrangement is made possible by utilizing a slack adjuster device as the one force-transmitting member.
