ABSTRACT:
The present invention provides an improved TMX.RTM truck mounted brake assembly for applying a brake shoe force to a railway car wheels by interfacing with an axle motion III bogie. The improvement comprises a rack and pinion type hand brake mechanism integrally mounted on at least one truck bogie per railway car. The hand brake mechanism utilizes a plurality of gear/pinion arrangements to transmit the force applied at the drive wheel to the transfer lever disposed within the TMX.RTM truck mounted brake assembly to effect the brake application. The hand brake mechanism is disposed within the spatial confines of the TMX.RTM truck mounted brake assembly and axle motion III bogie. The brake beams of the brake assembly are of the open box construction to accommodate such hand brake mechanism. A visual indicator is provided to identify the hand brake in both fully applied and fully released positions.
