Embodiment Construction

[0052] The technical solutions of the present invention will be described in detail by the following examples. The following examples are only exemplary, and can only be used to explain and illustrate the technical solutions of the present invention, but cannot be construed as limitations on the technical solutions of the present invention.

[0053] The present application provides an equal-section blade main and auxiliary spring assembly, such as Figure 3 to Figure 15 As shown, it includes FRP main spring blades, roll ears, front bushing, upper cover plate, lower backing plate, rear bushing, soft backing plate and FRP secondary spring blades.

[0054] Two ends of the FRP main spring blade are respectively fixed with a roll ear; the front bushing and the rear bush are respectively arranged in the roll ear.

[0055] The FRP auxiliary spring blade is arranged on the FRP main spring blade, and is fixedly connected through the upper cover plate and the lower backing plate.

Abstract

The invention relates to an equal-section blade main and auxiliary spring assembly. The equal-section blade main and auxiliary spring assembly comprises an FRP main spring blade, spring eyes, a frontlining, an upper cover plate, a lower base plate, a rear lining, soft base plates and an FRP auxiliary spring blade, wherein one spring eye is fixedly arranged at each of the two ends of the FRP mainspring blade; the front lining and the rear lining are separately arranged in the spring eyes; the FRP auxiliary spring blade is arranged on the FRP main spring blade, and is fixedly connected with the FRP main spring blade through the upper cover plate and the lower base plate; and the soft base plates are arranged between the upper cover plate and the FRP auxiliary spring main body, between theFRP auxiliary spring blade and the FRP main spring blade as well as between the FRP main spring blade and the lower base plate. A plate spring made of an FRP composite material does not break completely at a time, so that vehicle travelling safety is guaranteed, weight of a plate spring suspension frame is greatly reduced, and fuel oil effect is improved; and vehicle travelling smoothness is improved, and the service life of the longitudinal plate spring suspension frame is prolonged.

Description

technical field [0001] The invention belongs to the technical field of automobile leaf springs, in particular to a main and auxiliary spring assembly of equal-section blades. Background technique [0002] Leaf springs can be installed vertically or horizontally on the vehicle. The latter is only used in a few light and miniature vehicles because of the need to transmit longitudinal force, an additional guiding force transmission device must be set up, which makes the structure complex and the mass increased. The vertical leaf spring can transmit various forces and moments, has a guiding function, and has a simple structure, so it is widely used in automobiles. [0003] A composite material is a combination of two or more materials, which are combined through an effective interface between the materials, and whose performance is superior to the original material. There are many types of composite materials, such as reinforced concrete is also a composite material, concrete ...
