DEVICE TO INCREASE ROLL STABILITY OF RAIL VEHICLES WITH AIR SUSPENSION

摘要

Apparatus to increase roll stability of rail vehicles having air suspensions. The vehicle body is supported near each end by bogies and by two lateral air spring bellows, each having separate first and second levelling valves. One of the bogies has one air spring bellows controllable by means of a third levelling valve arranged in the region of the car center, and its other air spring bellows being connected with the air spring bellows of the first bogie on the same side of the car by means of an equalizing pipe. The latter bogie is formed with a roll stabilizer between the car body and the bogie frame, and emergency supports are provided at three points, one bogie featuring two emergency springs formed as rubber-bonded-metal composite springs and forming an integral unit with the air spring bellows and the other bogie featuring a central emergency spring which concentrically extends around the center pivot of the bogie.
