Embodiment Construction

[0017] The present invention as figure 1 , 2 shown.

[0018] A composite material leaf spring structure of equal cross-sectional area, including a composite material leaf spring body 1, the composite material leaf spring body 1 part is gradually widened along the length direction from the middle to both ends; the thickness gradually becomes thicker Thin so that its cross-sectional area is always equal.

[0019] The middle part of the composite leaf spring body 1 is fixedly connected to the composite leaf spring body 1 by a clamp 2 structure; the lifting lugs 3 are fixedly connected at both ends by bolts and nuts 4 and glued.

[0020] The composite material leaf spring assembly is composed of a composite material leaf spring main body 1, an intermediate clamp structure 2, lifting lugs 3, and bolts and nuts 4 to form an assembly.

[0021] The cross-sectional area of ​​the composite leaf spring body 1 along the length direction is equal everywhere; and according to the stress ...

Abstract

The present invention provides a blade spring structure made of composite materials and equal in sectional area. The blade spring structure comprises a blade spring body made of the composite materials, and the blade spring body made of the composite materials is widened and thinned gradually from the middle to two ends along the length direction, so that the cross sectional area of the blade spring body is equal constantly. The middle of the blade spring body made of the composite materials is fixedly connected with a hoop structure, and lifting lugs are fixedly connected to the two ends of the blade spring body through bolts and screws by means of gluing. The blade spring structure made of the composite materials and equal in sectional area has the advantages that by taking advantages of long fibers of the composite materials, the blade spring structure conforms to lightweight design thinking of a blade spring equal-stress beam completely, the service life of a blade spring can be prolonged greatly, a weight reduction effect is remarkable, more than 70% of weight can be reduced, and the blade spring made of the composite materials is extremely high in corrosion resistance by the aid of own composite material characteristics.

Description

technical field [0001] The invention relates to a series assembly of automobile leaf springs, in particular to a composite material leaf spring structure with equal cross-sectional area. Background technique [0002] The rapid development of the automobile industry has led to a sharp increase in car ownership, and it has also brought three major problems to the society: energy shortage, environmental pollution, and safety issues. Automobile energy saving, environmental protection, and safety are not only the development direction of international automobile technology, but also the requirements of my country's industrial policy. Reducing fuel consumption and reducing environmental pollution has become an urgent problem to be solved in the development of today's automobile industry. Realizing automobile lightweight is one of the most effective ways to save energy, and it is also an important goal pursued by international advanced automobile enterprises. [0003] The composit...
