Abstract: An arrangement for increasing the roll stability of rail vehicles equipped with air suspension. Two air spring bellows having integrated emergency springs of a first bogie are controlled by a respective leveling valve. In addition to these bellows, a roll stabilizer is provided, so that in the vicinity of the first bogie, the car body, when viewed in the horizontal direction, is nearly parallel to this bogie. So that when track twist is encountered, the second bogie can swing relative to the car body, only one of the air spring bellows of this bogie is controlled by a third leveling valve disposed in the center of the car body, while the other air spring bellows is connected via an equalizing line with one of the air spring bellows of the first bogie. A central emergency spring extends concentrically around the center pivot of the second bogie.

Abstract: A bolsterless bogie for rail vehicles has at least one link which is directly connected to the bogie frame and the rail vehicle center pivot by means of wear-free rubber joints and connecting pins. Rubber buffers limit the transverse motion between center pivot and bogie frame; vertical forces are transmitted by air-spring bellows arranged in the vehicle center plane between the underframe and the bogie side sill, and stops effective in the travel direction are provided between center pivot and bogie frame.

Abstract: A rail vehicle for the transport of heavy and/or bulky goods with one multi-axle driving mechanism each. The driving mechanisms are respectively arranged on both ends of said rail vehicle. The rail vehicle furthermore includes at least one bridge girder interconnecting the bogies at each end of said rail vehicle. Pivotally mounted on said at least one bridge girder by means of an interposed displaceable member is a beak of a loading bridge supported by said driving mechanisms. The displaceable member with a displacing device facing the vehicle end infinitely variably displaceably and/or arrestably is connected to the bridge girder. The displacing device which faces toward the central portion of the vehicle rigidly or movably connects the displaceable member by way of a pivot point or bolt fixedly guided on the beak to the beak which is rotatable about a joint. The two displacing devices are adapted by a controlling device to be controlled in conformity with each other.
