Embodiment Construction
[0039] Attached below Figures 1 to 6 Embodiments of the present invention are described in detail.
[0040]The main and auxiliary leaf spring assembly for automobiles includes a main spring 1 made of stacked metal leaf springs and an auxiliary spring assembly 2 stacked on the main spring 1. It is characterized in that the auxiliary spring assembly 2 includes a downward convex The arc-shaped auxiliary spring 21, the upper pressure plate 22 bonded to the middle position of the upper surface of the auxiliary spring 21, and the elastic gasket 23 bonded to the middle position of the lower surface of the auxiliary spring 21, the auxiliary spring 21 is a composite Material leaf spring, the edge of the upper pressing plate 22 is in elastic contact with the auxiliary spring 21.
[0041] Such as figure 1 In the main and auxiliary leaf spring assembly for automobiles shown, the auxiliary spring 21 and the main spring 1 are stacked up and down, and the auxiliary spring 21 is stacked on...

The invention discloses a main / secondary plate spring assembly for a vehicle. The assembly comprises a main spring formed by laminating metal piece springs, and a secondary spring module laminated on the main spring. The assembly is characterized in that the secondary spring module includes an arched secondary spring downwards projected, an upper pressing plate bonded in the middle position of the upper surface of the secondary spring, and an elastic gasket bonded in the middle position of the lower surface of the secondary spring; the secondary spring is a composite material plate spring; and the edge of the upper pressing plate is elastically contacted with the secondary spring. The main / secondary plate spring assembly for the vehicle can satisfy the vehicle lightness requirement, improve the vehicle driving comfort, prolong the service life of a plate spring and improve the use reliability of the plate spring; and the invention further provides a manufacturing method and a design method of the main / secondary plate spring assembly for the vehicle.
Description
technical field [0001] The invention relates to a main and auxiliary leaf spring assembly for automobiles, which belongs to the field of auto parts. The invention also relates to a manufacturing method and a design method for the main and auxiliary leaf spring assemblies for automobiles. Background technique [0002] Existing automobile leaf springs are generally composed of main springs and auxiliary springs stacked. There are three types. The first type is that both the main spring and the auxiliary springs use leaf springs, which are heavy, more energy-consuming, and have a longer fatigue life. 1. The safety and driving comfort of the car are not high. The second is that the main spring uses a composite material leaf spring, and the auxiliary spring is a leaf spring. Its bearing capacity is limited. In the case of full load or overload, the safety performance and driving adaptability are both Not enough, the third is that the auxiliary spring is a composite material lea...
