AI Technical Summary

Technical Problem

Traditional shock absorber structures are prone to resonance, and springs or damping materials are easily corroded, making the vibration absorption effect and efficiency difficult to meet the needs of certain places.

Method used

It adopts a composite spring structure, including a spring body and a polyurea elastomer sleeved on the outside, with mounting seats and inner and outer rings at both ends, and telescopic support components on the inside to form a sealing structure to improve vibration absorption efficiency and service life.

Benefits of technology

The vibration absorption efficiency is improved, the compression amount of the spring body is reduced, and one-way compression is ensured, thereby extending the service life, and corrosion is avoided through the sealing structure, which improves versatility.

Abstract

The utility model belongs to the technical field of buffering and damping, and particularly relates to a composite spring which comprises a spring body, a polyurea elastic body is sleeved on the outer side of the spring body, mounting seats are arranged at two ends of the polyurea elastic body, and an inner ring and an outer ring which are respectively abutted against the inner wall and the outer wall of the polyurea elastic body are arranged on the mounting seats. The spring body is located on the inner side of the inner ring and is always in a compressed state, and a telescopic supporting assembly is arranged between the two installation bases and located on the inner side of the spring body. By arranging the polyurea elastomer and the spring body which are sleeved with each other and arranging the telescopic supporting assembly on the inner side of the spring body, on one hand, the overall vibration absorption efficiency can be improved conveniently, on the other hand, the compression amount of the spring body can be reduced, one-way compression of the spring body can be guaranteed, and therefore the service life of the spring body is prolonged; and meanwhile, the spring body can be sealed by arranging the mounting seat, so that the spring body is prevented from being corroded, in addition, the overall mounting of the composite spring can be facilitated, and the universality is improved.
