Abstract The invention relates to a bogie for high-speed rail vehicles having an H-shaped bogie frame (1, 2), primary springs (7) cushioning-the bogie frame (1, 2), and a lateral bolster which is movable relative to the bogie frame, receives the coach body and is cushioned relative to the bogie frame via air springs (3). The object of the invention was to provide a bogie which has a low number of contact points with the coach body, which allows the arrangement of rotational retardations, which has a minimum constructional width and low weight, which permits small air spring bellows, which allows the installation of additional air reser- voirs (27) for the air springs (3) below the lateral bolster (4) and which has additional assemblies arranged at locations which keep the bearing components free from bending or torsional stresses. According to the invention, this object is achieved in that each air spring (3) is supported directly on the side wall of the bogie frame (1, 2), the lateral bolster (4) bears friction plates (10) on its upper side near to its transverse ends above its bearing on the air spring (3) for resting the coach body, the lateral bolster is movable relative to the bogie frame (1, 2) only vertically and horizontally transversely within a defined path and is guided horizontally in the longitudinal direction with play in guides (12) of the bogie frame, the lateral bolster (4) is connected to the coach body via a journal which transmits only horizontal forces, and can be freely rotated with the bogie frame relative to the coach body.
