Bolsterless pneumatic suspension bogie for rail vehicles

摘要

Multi-element rail vehicles for local transport are usually connected by a central bogie on which successive wagon bodies 1 and 2 are supported (Figure 1). According to the invention, this support is effected via air spring bellows 3, 4 which are arranged at the point of intersection of the cross-members 5, 6 with a longitudinal member 14. The longitudinal member 14 which is situated in the central longitudinal plane transmits the pulling forces and impact forces from one wagon body to the other. These forces are applied at both ends via in each case one impact-absorbing element 16 which is connected via a pin 15 to the wagon body 1 (Figure 1), the impact-absorbing element 16 being equipped with a spring tube 20 for the purpose of damping, which tube brings about the application of the forces to the cross-member 5 and the longitudinal member 14. For the purpose of lateral guidance of the wagon body 1, the pin 15 is mounted in the housing 18 of the impact-absorbing element 16 and the housing 18 is guided in a vertically sliding fashion in a U-shaped projection 19 of the cross-member 5. The connection of the wagon body 2 which can be seen in Figure 1 is effected in a symmetrical manner. By virtue of the integration of the longitudinal member 14 into the frame of the bogie, space and weight are saved and the axle spacings are also reduced. IMAGE
