ABSTRACT:
A railway truck assembly adapted to produce steering of the wheel axles radially to a curve to reduce wear and noise and characterized by a pivot connection between the bolster and the truck frame elements which; in cooperation with direct transmission of the load to the truck frame through the opposite ends of the bolster, allows to use a relatively thinner and centrally non-bulging bolster. Thus, more space is made available between the central portion of the bolster and the top of the rails; which space is advantageously used to install some equipment such as for instance a linear induction motor or LIM. This railway truck assembly comprises a bolster which is substantially bodily displaceable with the car body, a pair of side frames, laterally restrained relative to the bolster and supporting the opposite ends respectively of the bolster, a pair of steering yokes longitudinally restrained relative to the car body and pivoted one to the other for radial steering of the wheel axles connected to them respectively, the side frame being slidably supported by the yokes and laterally restrained relative to the latter, and links producing the aforementioned restraints respectively.
