  • Patent number: 4841874
    Abstract: A pneumatic-spring bogie, particularly for high-speed 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, first and second rubber buffers are provided that surround the bogie pin in the longitudinal and transverse directions respectively in order to drive the bogie. The free end of the bogie pin is pivotably connected by a damping member to the cross-member of the bogie frame. Advantageously, the pivot point of the bogie is placed in a region between the rubber buffers and the damping member. Secondary suspension is effected by a pneumatic-spring bellows that is disposed concentrically to the bogie pin.
