Abstract

The invention discloses an elastic wheel for rail transit. The elastic wheel comprises a wheel center assembly, a shock absorption element and a wheel rim with a central hole, wherein the shock absorption element is positioned between the wheel center assembly and the wheel rim, the wheel center assembly is positioned in the central hole of the wheel rim, and a gap S is formed between the wheel center assembly and the wheel rim; and the wheel center assembly comprises a flange plate and a wheel center with a hub hole, the wheel center is provided with an annular notch, the inner hole of the flange plate is sleeved on the bottom of the annular notch of the wheel center, the bottom of the annular notch is provided with an annular clamping groove, a clamping ring is arranged in the annular clamping groove, and the clamping ring is propped against the outer side of the flange plate. The elastic wheel has compact structure, and is safe, reliable and easy to disassemble and assemble, and the cost is saved.

Description

technical field [0001] The invention relates to an elastic wheel, in particular to an elastic wheel for rail transit. Background technique [0002] With the development of my country's urban rail transit and the extensive construction and use of urban subways and light rails, the problem of vehicle operation noise has seriously affected residents. The elastic wheel is a damping element embedded in a compressed state between metal parts, which can effectively reduce the vibration and noise when the vehicle is running. By adjusting the compression state of the damping element, the stiffness of the elastic wheel can be changed and the performance of the elastic wheel can be adjusted. [0003] However, the elastic wheel metal parts currently used generally adopt a bolted connection structure, which has high requirements for the strength of the bolts. When a certain bolt in a group of bolts fails due to quality or external force problems, the rest Bolts will bear more tension an...
