Embodiment

[0027] Such as figure 1 As shown, the embodiment of the present invention provides a serpentine spring, including: a plurality of spring units 1 , a stabilizing ring 2 , a first support seat 3 and a second support seat 4 .

[0028] The spring monomer 1 adopts a serpentine bending sheet structure, which realizes the stretchable mechanical properties of the spring. The sheet structure reduces the mass of the spring monomer 1 to a certain extent, thereby The mass of the serpentine spring is reduced.

[0029] The stabilizing rings 2 are polygonal annular structures, and each stabilizing ring 2 is sleeved on the bending part of the spring unit 1, and the spring unit 1 and the stabilizing ring 2 cooperate to form an external spline structure. Wherein, the number of spring monomers 1 is equal to the number of sides of the stabilizing ring 2, for example, if the number of spring monomers 1 is four, then the stabilizing ring 2 is a quadrilateral.

[0030] The first support seat 3 and...

Abstract

The invention discloses a snake-shaped spring comprising a plurality of sheet-like spring units bent into snake shapes, a plurality of stabilizing rings sleeving the spring units, a first supporting seat fixing first ends of the spring units and a second supporting seat fixing second ends of the spring units. The spring units match with the stabilizing rings to form an external spline structure. According to the snake-shaped spring, the spring units are in the hollow through external spline structure through the stabilizing rings and are in a stable spring assembly structure through the fixation of the first supporting seat and the second supporting seat; the snake-shaped spring is capable of stretching in the extending direction of the spring units and plays an ordinary spiral spring role; since the sheet-like structures made of glass fiber-epoxy resin material is adopted, the entire weight of the spring assembly can be reduced greatly; the reliability of the spring is guaranteed through the structure that the spring units match mutually, when one spring unit is in failure, the other spring units are capable of realizing the mechanical properties, and the failure of the spring assembly is avoided.

Description

technical field [0001] The invention relates to the field of design and manufacture of automobile suspension springs, in particular to a serpentine spring. Background technique [0002] Automobile suspension spring is an important part in the chassis structure of the vehicle. Its main function is to absorb the impact of the road surface. Generally, half of its mass is included in the unsprung mass, so its performance directly affects the ride comfort, handling stability and safety of the vehicle. The lightweight design of the frame spring is of great significance. In the prior art, steel coil springs or torsion bar springs are often used as the suspension springs of automobiles, but their large dead weight increases the unsprung mass of the vehicle, which restricts the ride comfort and handling stability of the vehicle. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a serpentine spring, which solves the pr...
