ABSTRACT:
This application discloses a railway vehicle truck of a general configuration having independently movable side frames, wherein the side frames are provided with resilient connections with the wheel-axle units which allow universal turning movement but substantially inhibit relative axial movement; wherein the side frames are connected at longitudinally spaced points by transverse cross-frame or transom bar members which are rigidly connected to the side frames at one end and connected to opposite side frames by true turning shaft-bearing joints which also, when needed, provide limited axial movement, the shaft-bearing joints having axes disposed on a line passing through the vertical axis of turning of the truck whereby the transom bars positively maintain the truck in tram; wherein a center frame is mounted at longitudinally spaced laterally central points on the transom bars by resilient joints which are spaced approximately the same distance from the transverse vertical central plane of the truck as the shaft-bearing turning joints of the transom bars on the side frames, the resilient joints providing considerable vertical turning movement but restricting direct vertical movement; wherein the center frame provides a true turning shaft-bearing joint with the truck bolster; wherein the truck bolster is turnably supported by resiliently backed bearing plates on supporting surfaces on the side frames; wherein the vehicle body is supported by air springs located directly upon and above the side frames, the air springs being of a type to assist materially in controlling transverse movements and, in conjunction with air reservoirs and suitable orifice or valve means to assist in controlling vertical ride dynamics of the vehicle; wherein a frame carrying a drive motor and axle drive means is supported by the center frame in such manner that the movements of the motor frame are kept within proper limits relative to the axles; and wherein a transverse anti-roll bar suspension is provided to control roll dynamics of the truck bolster and the vehicle or car body carried thereon.
