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. The friction block is not matched with the swing bolster through slopes, 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 a vibration reduction effect of the bogie in an unloaded state is ensured, and using reliability of the swing bolster is ensured.
