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.
A railway locomotive of the type comprising a carbody supported by a self steering truck including a pair of wheel and axle members, a truck frame including a pair of parallel side frames interconnected by at least one laterally extending transom, the truck frame being carried by the axles through resilient suspension means nominally urging the axles into centered positions for motion along straight track but permitting yawing for movement along curved track, traction motors drivingly connected with the axles for driving the locomotive wheels, one of the motors being carried on a side of said transom, first force transmitting linkage connecting the axles with the frame and including a lateral steering beam connected with at least one of the axles and having a center pivotally connected with the frame and free from connection with the carbody to allow self steering of its connected axle while carrying longitudinal forces between it and the frame, and second force transmitting linkage connecting the frame with the carbody and including the improvement of
A railway locomotive of the type comprising a carbody supported by a self steering truck including at least three longitudinally spaced wheel and axle members, a truck frame including a pair of parallel side frames interconnected by two laterally extending transoms each spaced longitudinally between one of the end axles and the remaining axles, the truck frame being carried by the axles through resilient primary suspension means nominally urging the axles into centered positions for motion along straight track but permitting yawing for movement along curved track, the carbody being supported on the truck frame by resilient secondary suspension means spaced laterally toward the side frames, traction motors drivingly connected with the axles for driving the locomotive wheels, two of the motors being carried on sides of the transoms, first force transmitting linkage connecting the axles with the frame and including a pair of lateral steering beams connected one with each of the end axles and each beam having a center pivotally connected with the frame and free from connection with the carbody to allow self steering of its connected axle while carrying longitudinal forces between it and the frame, means interconnecting said steering beams to require self steering yaw motions of the wheel and axle members to be of opposite sense and equal extent and the improvement wherein said interconnecting means includes
A railway locomotive of the type comprising a carbody supported by a steering truck including a pair of wheel and axle members, a truck frame including a pair of parallel side frames interconnected by at least one laterally extending transom, the truck frame being carried by the axles through primary suspension means permitting yawing for movement along curved track, first force transmitting linkage connecting the axles with the frame and including a lateral steering beam connected with at least one of the axles and having a center pivotally connected with the frame to allow steering of its connected axle while carrying longitudinal forces between it and the frame, and second force transmitting linkage connecting the frame with the carbody and including the improvement of
A railway locomotive steering truck including a pair of wheel and axle members, a truck frame including a pair of parallel side frames interconnected by at least two laterally extending transoms, the truck frame being carried by the axles through primary suspension means permitting yawing for movement along curved track, first force transmitting linkage connecting the axles with the frame and including a pair of lateral steering beams, one connected with each of the two axles and each having a center pivotally connected with the frame to allow steering of its connected axle while carrying longitudinal forces between it and the frame, and means interconnecting said steering beams to require self steering yaw motions of the wheel and axle members to be of opposite sense and equal extent and the improvement wherein said interconnecting means includes
