A trailer elastic wheel for a low-floor bogie comprises a hub, a wheel centre, a pressing ring and damping rubber. The wheel center is arranged in the center of the hub. The damping rubber is arranged between the wheel center and the hub and arranged into a V shape open towards the hub. The pressing ring is arranged between the damping rubber and the wheel center and presses the damping rubber. A rim used for preventing the hub from being derailed is arranged around the hub and protrudes in an arc mode along one side of the hub, the thickness of the rim is 1/2 that of the hub, and when the hub is arranged on a rail, the rim is located on the inner side of the rail. A bearing hole is formed throughout the center of the wheel center. Axial or radial vibration of the wheel can be buffered, the damping range is wide, and the damping effect is good.
