  • Truss-type brake beam for railway vehicle truck-mounted brake assembly
    Patent number: 4830148
    Abstract: A truss-type brake beam having a bent configuration in which the compression and tension members are bent on opposite sides of a strut member, so that the compression and tension member segments lie in separate planes that intersect to form an angle therebetween, the line of intersection being rectilinear. The bent configuration of the brake beam accommodates housing of a brake-cylinder in the pocket between the compression and tension members adjacent the strut member, facilitates passage of force-transmitting rods between the companion brake beams of a given truck, and permits application of brake beam actuating forces without imparting torque moments to the beam.
