ABSTRACT:
A bogie or truck for high-speed rail vehicles or railway cars includes an H-shaped bogie or truck frame, primary springs cushioning the bogie frame, and a lateral bolster being movable relative to the bogie frame, receiving a coach or car body and being cushioned relative to the bogie or truck frame by air springs. The object is to provide a bogie with a low number of contact points with the coach body, which allows a configuration for rotational retardation, which has a minimum structural width and low weight, which permits small air spring bellows, which allows the installation of additional air reservoirs for the air springs below the lateral bolster and which has additional assemblies disposed at locations which keep the bearing components free from bending or torsional stresses. According to the invention, each air spring is supported directly on the side wall of the bogie frame. The lateral bolster carries friction plates on its upper surface near its transverse ends above its bearing on the air spring for supporting the coach body. The lateral bolster is movable relative to the bogie frame only vertically and horizontally transversely within a defined path and is guided horizontally in the longitudinal direction with play in guides of the bogie frame. The lateral bolster is connected to the coach body through a journal which transmits only horizontal forces, and can be freely rotated with the bogie frame relative to the coach body.
