Air spring steel wire ring, winding disc and air spring with steel wire ring

Abstract

The invention relates to the technical field of air springs, in particular to an air spring steel wire ring, the cross section structure of the air spring steel wire ring is composed of a plurality of steel wires which are sequentially and tightly arranged, the cross section structure is in a hexagon shape, each inner angle of the hexagon is 120 degrees, the hexagon comprises long edges and short edges with different lengths, and the long edges and the short edges are arranged in a staggered mode. The steel wire arrangement on the long edge is composed of at least three steel wires, the steel wire arrangement on the short edge is composed of at least two steel wires, and the side, close to the middle of the air spring steel wire ring, of the section structure is the long edge. The air spring steel wire ring is reasonable in structural design, wrapping and apex filling can be reduced for a steel wire lap, circumferential material transition is more uniform, product defects caused by the steel wire lap are avoided, the production efficiency and the product percent of pass can be effectively improved, and therefore actual requirements can be better met.

Description

technical field [0001] The invention relates to the technical field of air springs, in particular to an air spring traveler, a winding disk and an air spring with the traveler. Background technique [0002] Air spring refers to a spring that is filled with compressed air in a retractable airtight container and uses air elasticity. As a product with excellent shock absorption performance, air spring is widely used in rail vehicles and high-end automobile shock absorption systems. The upper and lower toes of the air spring are generally equipped with steel rings. [0003] Most of the existing air spring travellers are wound with multiple steel wires, and the cross-section is square. It is necessary to wrap the steel wire laps and fill them with apex rubber, resulting in low work efficiency and uneven material transition in the circumferential direction. The head part is easy to expose the wire, the strength of the traveler is low, and the square shape of the air spring travel...
