ABSTRACT OF THE DISCLOSURE A bolsterless bogie with air suspension for rail vehicles where an underframe is connected directly by means of a centre pivot and wear-free link without the intermediary of a bolster to the bogie frame is disclosed. The connection is effected by means of at least one link which is disposed hori- zontally and pointing in the direction of travel preferably at the level of the axle boxes to the centre pivot and the bogie frame, and the pins of the connection are supported in wear-free rubber joints and are disposed horizontally and transversely to the direction of travel. Rubber buffers are provided to limit the transverse motion between the centre pivot and the surrounding bogie frame with vertical forces being transmitted by means of air-spring bellows arranged in the transverse centre plane between the underframe and the bogie side still. Stops effective in the travel direction are provided between the centre pivot and the bogie frame.
