Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, a composite material stabilizer bar is U-shaped, and the cross section of its shaft 4 is circular; the shaft 4 of the stabilizer bar includes a central layer 3 and one or more layers wrapped outside the central layer 3 A wrapping layer; the wrapping layer is composed of a composite material woven with reinforcing fibers.

[0031] Since the stress condition on the outermost surface of the stabilizer bar is the worst, the weaving method of the reinforcing fiber in the composite material in the outermost wrapping layer 1 adopts the plain weave method, that is, the reinforcing fibers in the warp and weft directions are cross-woven to form a plain weave 6 The plain weave cloth 6 can not only ensure the strength of the shaft 4, but also enable the shaft 4 to be cove...

Abstract

The invention discloses a preparation method of a composite transverse stabilizer bar and the transverse stabilizer bar prepared by the preparation method. The preparation method comprises the following steps of step 1, preparing a transverse stabilizer bar preform according to the designed size and shape of the transverse stabilizer bar, specifically, preparing a central layer and a wrapping layer of the transverse stabilizer bar according to design requirements, and splicing a central layer material rod and the wrapping layer to form the transverse stabilizer bar preform; step 2, curing thetransverse stabilizer bar preform, specifically, putting the transverse stabilizer bar preform into a mold, and injecting resin into the mold to be cured; and step 3, post-curing and post-processing the transverse stabilizer bar. According to the preparation method, the bar body of the manufactured transverse stabilizer bar comprises the central layer and one or more wrapping layers wrapping the central layer, the wrapping layer is a composite material weaved by reinforced fibers, and the bar body is of a solid structure or an internal hollow structure. The preparation method is high in efficiency, and the prepared stabilizer bar has the advantages of being light in weight, high in strength and not prone to rusting.

Description

technical field [0001] The invention belongs to the field of automobile lateral stabilizer bars, and in particular relates to a method for preparing a composite material lateral stabilizer rod applied to automobile suspensions and the prepared lateral stabilizer rods. Background technique [0002] With the continuous upgrading of automobile emission standards and the increasingly serious problems of energy shortage and environmental pollution, automobile lightweight has become the main development trend of modern automobiles. The stabilizer bar is one of the key components of the automobile suspension system. Its function is to provide the stiffness of the car's roll angle and prevent the body from excessive lateral roll when turning, so as to keep the body balanced and improve the ride comfort of the car. . If the transverse stabilizer bar breaks during the turning process of the car, it will cause the body to lose stability and induce safety accidents such as rollover. T...
