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.

Embodiment Construction

[0048] figure 1 A schematic perspective view of a composite primary and secondary spring assembly 100 according to an embodiment of the present invention is shown. The composite main and auxiliary spring assembly 100 may generally include a main spring 110 , an auxiliary spring 120 and a first spacer 130 . The main spring 110 may be made of metal material, or at least partially made of metal material. The auxiliary spring 120 is made of composite material, which can greatly reduce the weight of the main and auxiliary spring assembly. In order to reduce or even eliminate the friction between the main spring 110 and the auxiliary spring 120 , the first spacer 130 can be arranged between the main spring 110 and the auxiliary spring 120 . In one embodiment, the main spring 110 , the secondary spring 120 and the first spacer 130 are connected by a central bolt 241 . It can be understood that in other embodiments, the main spring 110 , the secondary spring 120 and the first space...

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.
