Man Gutehoffnungsh?tte Gmbh Nuremberg, 15 January 1987. The invention relates to a pneumatic spring bogie, more particularly for fast-running rail vehicles. These vehicles need a drive device for the bogie, which transmits not only tensile and impact forces but also absorbs vibration, particularly in the longitudinal direction. To this end, according to the invention, first and second rubber buffers 10, 11 are provided and surround the bogie pin 6 in the longitudinal and transverse direction respectively, in order to drive the bogie. The free end of pin 6 is pivotably connected by an antivibration member 14 to the cross-member 3 of the bogie frame. Advantageously the pivot point of the bogie is placed in a region between the rubber buffers 10, 11 and the antivibration member 14. The secondary suspension is by a pneumatic spring bellows 2 disposed concentrically with pin 6. The drive device and secondary suspension according to the invention considerably simplify the construction, in that the longitudinal member of the bogie does not need to be bent at right angles, and there is no need for connecting cods for driving the bogie or for longitudinal vibration absorbers at the sides (Fig. 1). |
