ABSTRACT:
An arrangement for locomotives and other railway vehicles having steerable or self-steering railway trucks, particularly motorized locomotive trucks, which incorporates axle height transfer of loads from the axles to the frame through connecting rods and steering beams connecting with the end axles. The steering beams are interconnected through upstanding torque tubes, cranks and a high level diagonal link extending over intermediate traction motors or other equipment. A bolsterless suspension of rubber pads supports the carbody with traction and braking loads being transferred through linkage including a carbody post carrying a short pivotally mounted carbody beam attached by connecting rods to an adjacent transom of the truck frame. The arrangement provides a compact and efficient force transfer system with low axle weight transfer while permitting interrelated self-steering action of the front and rear axles, but is also adaptable to forced steering truck arrangements.
