ABSTRACT:
A truck comprising a pair of longitudinal side frames with axle assemblies located at opposite ends thereof. Diagonal braces extend between the side frames to provide the truck with a lateral stiffness and a yaw stiffness. The diagonal braces include struts extending between the side frames and connected thereto by elastomeric members. The elastomeric members provide controlled flexibility in shear for the truck and are chosen so that the yaw stiffness and lateral stiffness lie on the characteristic curve of maximum critical velocity. In this way maximum stability of the truck is obtained.
