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.

Abstract: A radial axle railway truck has separate depressed center beam-type side frames mounted at their ends on journal bearing assemblies by means of elastomeric pad devices between downwardly facing surfaces on the side frames and upwardly facing surfaces on the bearing assemblies, the pad devices near the ends of the side frames being at a level higher than the axle centers and laterally inboard of the side frames and those remote from the ends of the side frames being at a level lower than the axle centers and laterally outboard of the side frames, thereby conforming with sloping end portions of the side frames and stabilizing the side frames against tipping transversely. The main frame of the truck has longitudinally extending side members and the side frames mount vertically acting resilient means for supporting the main frame on the side frames.

Abstract: A radial axle railway truck has a pair of depressed center side frames supported at their ends from the axles by horizontal elastomeric pad devices carried on the sides of outboard journal bearing adapters to permit steering movements of the axles, the horizontal pad devices nearest the ends of the side frames being elongated transversely of the truck and the horizontal pad devices remote from the ends of the sideframes being elongated longitudinally of the truck. A transverse truck frame is supported at each side above the depressed center portion of the respective side frames by a pair of generally V-shaped elastomeric pad devices supported on the inclined portions of the side frames connecting the high end portions and the depressed center portions thereof.

Abstract: A bogie truck car body support system wherein a car body is directly supported on a truck frame by bolster springs, the system including a link arranged longitudinally of the car body and connected at one end to a link support which is fixed to the car body by a play-free shock absorber and at the other end to a pin through a play-free shock absorber and a bush rotatably fitted on the pin. The car body has neither the bush nor center pin directly connected thereto which might become wobbly. The system can be readily assembled and disassembled and is capable of reducing vibration and noise transmitted from the truck to the car body.

Abstract: A bolsterless bogie for rail vehicles has at least one link which is directly connected to the bogie frame and the rail vehicle center pivot by means of wear-free rubber joints and connecting pins. Rubber buffers limit the transverse motion between center pivot and bogie frame; vertical forces are transmitted by air-spring bellows arranged in the vehicle center plane between the underframe and the bogie side sill, and stops effective in the travel direction are provided between center pivot and bogie frame.

Abstract: A basic truck for a railway car includes a pair of side frames connected by suitable transverse disposed members. Standard structural members for holding different types of suspension and journal bearings of the car are provided and are secured to the end of the side frames at predetermined locations dependent upon the types of suspension and journal bearings used. Gusset members designed in accordance with the operating car requirements are connected to provide the principal structural connections between the mountings and the side frames.

Abstract: In a railway car truck a transom is provided comprising a pair of tubes rigidly connected respectively to a pair of longitudinally extending side frames. The tubes are longitudinally and vertically aligned and are located below a bolster which extends between the side frames above the transom. A bearing rigidly attached to one of the tubes extends within the other of the tubes. The external surface of the bearing is provided with low friction material to allow the side frames to rock in respective vertical planes about a transverse axis as ups and downs in the track are transversed. However, the transom resists the tendency for the side frames to move longitudinally with respect to each other, and thus maintains the truck in tram.

Abstract: A bogie with a torsion-soft corner-stiff frame for high speed rail vehicles with a wear-resistant means interconnecting the central areas of the longitudinal beams of the bogie together with one wear-resistant means each interconnecting the longitudinal beam ends. Of the wear-resistant means, that means which is located within the region of the vertical transverse plane is designed as an intermediate joint permitting movements solely about the y-axis, whereas the wear-resistant means at the ends form components of horizontal spring leaves which form head pieces of the bogie. The ends of said spring leaves are in a corner-stiff manner connected to stiff corner pieces arranged at the ends of the longitudinal beams.

Abstract: A rigid type truck or bogie frame in which the cross-member or bolster is secured at its end portions to a laterally extending central portion of each side member includes a cylindrical portion registering with the main body of the cross-member or bolster and to which the respective ends of the cross-member or bolster are secured as by by butt welding. Each central portion has an upper substantially flat face, a lower slightly convex face and two pairs of laterally protruding swells so as to reduce stress concentrations.

Abstract: A span bolster arrangement for interconnecting a pair of railway trucks and mounting a railway vehicle chassis, the span bolster arrangement including a span bolster structure having side members interconnected by lateral members and being mounted on and connected to a pair of railway trucks located beneath opposite ends thereof. The span bolster structure carries a plurality of elastic chassis support pads including primary load bearing pads and secondary stabilizing pads, which pads engage the underside of a vehicle chassis. The arrangement of the pads is such that axes of the pads intersect at a virtual point on a longitudinal central plane of the span bolster structure and approximately midway between the pair of trucks and at a height substantially corresponding to rail level.

Abstract: An improved railway stock railway rolling stock bogie truck includes a cross beam and a pair of spaced longitudinal side members with an asymmetrical cross-sectional configuration with the cross beam in alignment both with the bearing support and the side members.

Abstract: In a railway car truck a transverse member is provided including spaced sides and a member joining said sides to define a hollow portion having an open bottom such that the shear center is spaced upwardly from the neutral axis of the section. A truck center bearing is provided at about the mid portion of said transverse member which is located at about said shear center so that torsional deflection or twisting of the transverse member is avoided.

Abstract: In accordance with the present invention a railway car truck is provided including a pair of transversely spaced side frames and a transom which is attached solely to the side frames with a rigid connection to define an integral H frame to maintain the side frames parallel and resist truck hunting. The transom has a cross section which provides torsional flexibility which allows the side frames to rock relative to one another. Above the transom a bolster is provided which extends transversely between the side frames and rests upon spring assemblies mounted in openings in the side frames. The weight of the car body is by car body bearing assemblies mounted on the bolster above the spring assemblies. A bolster center bearing is provided which engages the car body and transmits substantially all horizontal loads from the car body through the bolster to the side frames.
