Abstract

See full text

The disclosure discloses a swing bolster, a swing bolster vibration reduction assembly and a bogie. The swing bolster includes a body, wherein a mounting cavity for mounting a friction block is formed in two ends of the body; the mounting cavity is provided with a first horizontal opening and a second horizontal opening, which are opposite to each other; and opening directions of the first horizontal opening and the second horizontal opening are perpendicular to an extending direction of the body. When the swing bolster in the disclosure is used, the friction block is mounted in the mounting cavity of the swing bolster body, and end parts of the friction block extend out of the first horizontal opening and second horizontal opening of the mounting cavity. The friction block is not matched with the swing bolster through sloped portions, and a movement direction of the swing bolster is perpendicular to a movement direction of the friction block relative to the swing bolster, so that wear of the friction block and the swing bolster is reduced, influence caused by the relative movement or wear of the swing bolster and the friction block to vibration reduction performance of the vertical elastic elements is prevented, a vibration reduction effect of the bogie in an unloaded state is ensured, and using reliability of the swing bolster is ensured.
