Composite material main and auxiliary spring assembly and suspension

Abstract

The invention provides a composite material main and auxiliary spring assembly. The assembly comprises a main spring, an auxiliary spring and a first cushion block, wherein at least part of the main spring is made from metal, the auxiliary spring is made from a composite material, and the first cushion block is arranged between the main spring and the auxiliary spring and used for preventing the metal part of the main spring from making contact with the auxiliary spring; the first cushion block comprises a metal block body and a rubber component, the metal block body is provided with a surfacemaking contact with the auxiliary spring, and the rubber component is arranged to extend in the circumferential direction of the stressed edge of the surface of the metal block body. The invention further provides a suspension provided with the composite material main and auxiliary spring assembly. According to the scheme, cushion blocks or pressing plates of the structure same as that of the cushion blocks, non-metal blocks and the like are arranged at the stress part, making contact with the composite material, of metal materials, so that the metal materials do not rub with the composite materials, the NVH problem caused by friction between traditional plate springs is eliminated, and the coulomb damping between the plate springs is avoided.

AI Technical Summary

Benefits of technology

This patented technology relieves heavyweight from vehicles' shocks through suspending heavier parts like tires and wheels within them. It achieves this by utilizing both metals (mainly aluminum) along its length for strength while also adding other features such as elastic behavior, biaxial tensile property, and specific orientation. These technical improvements improve energy efficiency and protect against damage during crashes without compromising safety standards.

Problems solved by technology

The technical problem addressed by this patented technology relates to reducing weight without compromise on durability while maintaining good performance characteristics when making use of laminate type composite materials (LFs) with different thicknesses.
