A torque box includes a front plate and a bottom surface. The bottom surface is coupled to the front plate such that the bottom surface is orthogonal to front plate and such that front plate extends along the bottom surface. The bottom surface defines a first raised portion configured to fit over a wheel of a railcar.

A truck apparatus for a railway car includes a pair of wheel sets each having a pair of wheels joined by an axle. A frame is provided for carrying one end of a railway car body and a system positions the frame in a pendulum fashion from each axle end in order to independently decouple, from each other, vertical, lateral and longitudinal forces applied to the frame by the wheel sets during operation of the railway car.

Truck apparatus for railway cars

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.
