Disclosed are a bolster comprising a main body (10), wherein two ends of the main body (10) both have a mounting cavity (11) used for mounting a friction block (20), the mounting cavity (11) has a first horizontal opening (11a) and a second horizontal opening (11b) provided opposite each other, and the directions of opening of the first horizontal opening (11a) and the second horizontal opening (11b) are both perpendicular to the extension direction of the main body (10); a bolster vibration-damping assembly comprising a bolster and a vibration-damping part, wherein the vibration-damping part comprises the friction block (20), a horizontal elastic element (30) and a vertical elastic element (40), the friction block (20) is mounted in the mounting cavity (11) of the bolster main body (10) and an end part of the friction block extends out of the first horizontal opening (11a) and the second horizontal opening (11b) of the mounting cavity (11); and a bogie comprising the bolster vibration-damping assembly and a side frame (80), wherein the bolster vibration-damping assembly is provided on the side frame (80). Since the friction block (20) matches the bolster without using an inclined face, and the direction of movement of the bolster is perpendicular to the direction of movement of the friction block (20) relative to the bolster, abrasion between the friction block (20) and the bolster is reduced, ensuring that the relative movement or the abrasion of the bolster and the friction block will not affect the vibration-damping performance of the vertical elastic element (40), thereby ensuring a vibration-damping effect for the bogie when a vehicle is empty, ensuring reliability of use of the bolster.
