Detailed Description

In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined below to clearly and completely describe the technical solution of the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments, which can be derived from the description of the embodiments of the present invention by a person skilled in the art, are within the scope of the present invention.

As shown in fig. 1 to 2, the vehicle body assembly according to the embodiment of the present invention includes a vehicle body 10, an axle 13, and a belleville spring element, wherein the vehicle body 10 is disposed above the axle 13, the vehicle body 10 is spaced apart from the axle 13, the bottom of the belleville spring element is connected to the axle 13, and the top of the belleville spring element is connected to the bottom of the vehicle body 10. Through set up the belleville spring component between automobile body 10 and axle 13, have better cushioning effect, the empty offset frequency change fully loaded of vehicle is less, can make the vehicle all have higher travelling comfort when empty fully loaded, improves and uses experience.

Alternatively, the disc spring member may be provided in plural numbers, and the plural numbers of the disc spring members may be arranged at intervals in the width direction of the vehicle axle 13. For example, the two belleville spring elements are arranged at intervals along the width direction of the axle 13, so that the better buffering effect is achieved.

Optionally, the belleville spring element comprises a belleville spring comprising: the spring comprises a first butterfly spring 11 and a second butterfly spring 12, wherein the first butterfly spring 11 is in a shape of a conical disc, the second butterfly spring 12 is in a shape of a conical disc, and the first butterfly spring 11 is connected with the edge of the second butterfly spring 12. Wherein, the concave profile of the first belleville spring 11 is arranged opposite to the concave profile of the second belleville spring 12, so as to generate better buffer effect.

Specifically, each belleville spring element comprises a plurality of belleville springs, the belleville springs are stacked in the vertical direction, and the belleville springs are used in combination so as to achieve a good using effect.

Optionally, the belleville spring element is a carbon fiber material piece, so that the requirement of a light vehicle can be met, namely the service quality of the vehicle is reduced, and meanwhile, the service life of the elastic element can be prolonged.

During application, the belleville springs can be used singly or in series, and bear axial static or dynamic loads on the upper inner edge and the lower outer edge. The spring deforms as it is compressed, with increasing load until it flattens. The belleville springs have the following advantages over other springs: the axial size is small, the radial size is large, the bearing device can bear larger load under small deformation, the deformation energy per unit volume is larger, and the buffer and vibration reduction capability is better; has variable rigidity, and different characteristic curves can be obtained by changing the ratio of the disc thickness to the inner cone height under the condition of unchanging the inner diameter and the outer diameterThe reasonable design ensures that the offset frequency is kept low and basically unchanged when the vehicle is empty and fully loaded, thereby improving the riding comfort; different suspension deformation and rigidity characteristics can be realized through different combination forms of the disc; in the combined disk, the damage occurs individually, and only a certain damaged disk is replaced, thereby reducing the maintenance cost; the service life of the device can be prolonged by correct design, manufacture and use; is convenient for standardization and mass production, thereby reducing the cost. The carbon fiber is a special fiber composed of carbon elements, is fibrous and soft in appearance, can be made into various fabrics, and has high strength and modulus in the fiber axial direction due to the preferred orientation of graphite microcrystals along the fiber axial direction. The carbon fiber has low density and high specific strength-to-modulus, and is the highest specific strength-to-modulus in the existing engineering material. The density of the carbon fiber is 1.5-2.0g/cm³The tensile strength is more than 2400MPa, and the density of the spring steel is 7.8g/cm³Carbon fibres therefore have an absolute advantage compared to spring steel.

The carbon fiber has corrosion resistance, high strength and the like, so that the belleville spring has high tensile strength and fatigue strength; the carbon fiber density is small, so that the weight of the spring is greatly reduced, and the requirement of a light vehicle type is met to the greatest extent. In general, compared with the elastic element of the conventional vehicle suspension, the elastic element has the advantages of high strength, long service life, nonlinear rigidity and light weight, and can reduce the preparation quality to meet the requirement of light vehicle types; the carbon fiber material is also easy to be made into a tapered disc-shaped part from the aspect of manufacturing process. The rigidity of each group of springs can be 42N/m, the load borne by each group of springs is 5900N, therefore, the offset frequency of the suspension is 1.33Hz, the requirements of common passenger vehicles are met, the weight of the metal springs is 4.38Kg, and the weight is only about 0.95Kg after carbon fibers are adopted.

The utility model provides a vehicle, including the automobile body subassembly in the above-mentioned embodiment. The empty offset frequency change of fully loading of vehicle is less, can make the vehicle all have higher travelling comfort when empty fully loading, improves and uses experience.

Other structures and operations of the vehicle according to the embodiments of the present invention will be understood and readily implemented by those skilled in the art, and thus will not be described in detail.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
