W-shaped rubber ring elastic wheel

Abstract

The invention discloses a W-shaped rubber ring elastic wheel which comprises a rim, a wheel core, a jump ring and an elastic element with a W-shaped cross section. The jump ring is mounted on the wheel core through press fit. Twelve cylindrical countersunk holes are uniformly distributed on the jump ring along the circumference. The wheel core is provide with twelve threaded holes correspondingly. Twelve connecting fasteners penetrate the cylindrical countersunk holes on the jump ring and are connected with the threaded holes of the wheel core in threaded connection. The elastic element is mounted in a gap among the rim, the wheel core and the jump ring. Furthermore two ends of the elastic element are respectively connected with two end surfaces of a rim annular groove and a crossette on the jumper ring and a crossette on the wheel core, thereby preventing wheel derailing when an elastic component fails, and improving wheel safety in driving, wherein interference fit is realized between the elastic element, the rim, the wheel core and the jump ring. According to the W-shaped rubber ring elastic wheel, under a precondition that high performance of the elastic wheel is ensured, the mass under a wheel spring is reduced as possible, thereby facilitating mounting, detachment and maintenance, and furthermore realizing purposes of reducing vibration and noise.

Description

technical field [0001] The invention relates to the field of ammonia nitrogen detection, in particular to a W-shaped rubber ring elastic wheel. Background technique [0002] In recent years, my country's urban rail transit has developed rapidly. However, the vibration and noise generated by urban rail vehicles during operation have a great impact on the work and life of passengers and residents along the line. At present, in order to solve the impact of vibration and noise of urban rail transit, rubber elastic wheels are mostly used to slow down and eliminate. Rubber is embedded between the wheel tire and the wheel core to reduce the unsprung mass of the wheel set and reduce the vertical impact acceleration between the wheel and rail; use rubber to absorb high-frequency vibration, ease the impact, reduce noise and improve the friction of the wheel and rail ; Through the elastic deformation of the rubber, the friction between the wheel rim and the rail is greatly reduced whe...
