Abstract

The invention relates to an automobile plate spring assembly with main and auxiliary springs made from a composite material. The automobile plate spring assembly comprises a main spring, an auxiliary spring, a lower metal clamping plate, an upper metal clamping plate and a U-shaped bolt metal clamping plate, wherein the lower metal clamping plate, the auxiliary spring, the main spring, the upper metal clamping plate and the U-shaped bolt metal clamping plate are sequentially stacked from bottom to top, and then are clamped and fixed through two U-shaped bolts; the two ends of the body of the main spring are separately connected with two metal joints through bolts; rubber bushings are in interference fit in the metal joints; and the main spring and the auxiliary spring are plate springs made from composite material. The invention further relates to an assembly method for the automobile plate spring assembly. According to the automobile plate spring assembly and the assembly method thereof, a groove is formed in the middle of the upper surface of the spring body of the auxiliary spring so as to match with a lug boss below the spring body of the main spring; a lug boss with the same shape is processed in the lower surface of the auxiliary spring so as to match with a groove in the upper surface of the lower metal clamping plate; in the case of not drilling in the middle part, positioning and transmitting of longitudinal load are completed, so that the strength of a middle dangerous section is improved, the loading application and light weight of the plate spring made from the composite material are realized, and therefore, the automobile plate spring assembly is popularized and applied, and is of great significance.

Description

technical field [0001] The invention belongs to the field of auto parts, and in particular relates to an automobile leaf spring assembly with composite material main and auxiliary springs and an assembly method thereof, which is suitable for automobile suspension systems. Background technique [0002] Compared with leaf springs, composite leaf springs have obvious advantages in light weight, and their fatigue life is high, which is conducive to improving the ride comfort of the vehicle, and has broad application prospects. The main and auxiliary spring structure can better meet the frequency deviation requirements of the suspension system of the vehicle when it is no-load and full-load, and is conducive to improving the comfort of the vehicle. At present, the traditional main and auxiliary spring connection structure is to drill a hole in the middle and connect and locate through bolts. However, the working environment of automobile leaf springs is harsh. For composite leaf...
