Composite coil spring

Abstract

The invention discloses a composite spiral spring. The spring wires are of the equal pitch; each spring wire is of a two-layer structure; the outer layer is a metal layer; and the inner layer is shearing thickening glue. By means of the spiral spring composited with the shearing thickening glue, static loads express the linear characteristic, and dynamic loads have the non-linear rigidity and damping characteristics because of the unique mechanical performance of the shearing thickening glue. The defects of existing springs are well overcome.

Description

technical field [0001] The invention belongs to a mechanical transmission device, in particular to a nonlinear spring device. Background technique [0002] As a commonly used mechanical component in shock absorption and isolation applications, spring has many performance requirements. At present, although most coil springs have been applied in practice, they mainly use their geometric structure to achieve the goal. Variable pitch and variable cross-section make the geometric structure of the spring uneven, resulting in low service life of the spring, and the static load does not have linear characteristics. And the coil spring damping performance is poor at present. Contents of the invention [0003] In order to solve the shortcomings of the existing technology, a composite coil spring is provided. This composite coil spring has a simple and reasonable structure and is easy to install. It can not only maintain its linear characteristics under static load, but also utilize...
