AI Technical Summary
Traditional round tube beam axles are heavy, have low processing efficiency, cannot meet the market demand for micro and light trucks, and have weak resistance to deformation.
A wave-shaped web I-beam front axle is designed. By reducing the thickness and width of the upper web and the thickness of the middle web of the I-beam, and increasing the wave-shaped structure of the middle web, the cross-sectional area of the I-beam is reduced by 29.5%, thereby improving the bending fatigue strength and deformation stiffness.
This achieved a 12.5% weight reduction for the front axle of the I-beam while improving bending resistance, meeting the market demand for micro and light truck products.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive front axle technology, specifically a wave-shaped web I-beam front axle. Background Technology
[0002] The front axles used in micro and light trucks are primarily circular tube beam axles. However, with increasingly stringent quality requirements from customers and end-users, the quality of circular tube beam axles can no longer meet their needs. The overall processing equipment for circular tube beam axles is inefficient, and its production volume cannot meet the market demand for micro and light trucks. Under the same load conditions, such as a rated load of 2000kg, the traditional circular tube beam axle front axle is not only heavier but also has weaker resistance to deformation. Utility Model Content
[0003] To address the aforementioned problems, the purpose of this invention is to provide a front axle for a wave-shaped web I-beam.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a wave-shaped web I-beam front axle, comprising an I-beam and a front axle body disposed at both ends of the I-beam, the front axle body extending obliquely outward and provided with a front axle tube, the I-beam comprising a horizontal upper web and a lower web, the upper web and the lower web being fixedly connected by a vertical intermediate web, so that the upper web, the intermediate web and the lower web form an I-beam with an I-shaped cross section, and the horizontal cross section of the intermediate web is wave-shaped.
[0005] Furthermore, mounting plates with a width greater than that of the upper web plate are respectively provided at both ends of the upper web plate, and hollow mounting holes are respectively provided at the front and back of the mounting plates.
[0006] Furthermore, the thickness of the parts where the upper and lower webs are fixedly connected to the intermediate webs is greater than the thickness of their respective outer edges.
[0007] Furthermore, the front axle body, upper web, lower web, and intermediate web are integrally machined.
[0008] Furthermore, the wavelength of the wavy structure in the middle web is 26.67 times the wave height.
[0009] Furthermore, the lower web is thicker than the upper web.
[0010] With the above settings, the structural design of this utility model is more reasonable. By reducing the thickness of the upper web of the I-beam, the width of the upper and lower webs of the I-beam, and the thickness of the middle web, the cross-sectional area of the relative circular tube beam is reduced by 29.5%, achieving a 12.5% weight reduction in the front axle of the I-beam. In addition, the height of its I-beam cross-section is higher than that of the circular tube beam cross-section, which improves the bending fatigue strength of the front axle. The middle web is designed in a wave shape to improve the bending deformation stiffness of the front axle. That is, while reducing the overall weight, it can also improve the bending resistance of the front axle. Attached Figure Description
[0011] The present invention will now be further described with reference to the accompanying drawings.
[0012] Fig. 1 This is a schematic diagram of the main structure of this utility model; Fig. 2 This is a top view of the structure of this utility model; Fig. 3 This is a schematic diagram of the cross-sectional structure of the I-beam portion of this utility model. Detailed Implementation Example
[0013] like Figs. 1-3 As shown, a wave-shaped web I-beam front axle includes an I-beam and a front axle body 1 set at both ends of the I-beam. The front axle body 1 extends obliquely outward and is provided with a front axle tube 2. The I-beam includes a horizontal upper web 3 and a lower web 4. The upper web 3 and the lower web 4 are fixedly connected by a vertical intermediate web 5, so that the upper web 3, the intermediate web 5 and the lower web 4 form an I-beam with an I-shaped cross section, and the horizontal cross section of the intermediate web 5 is wave-shaped.
[0014] Specifically: At both ends of the upper web plate 3, there are mounting plates 6 with a width greater than that of the upper web plate 3, and the front and rear of the mounting plates 6 are respectively provided with hollow mounting holes. The thickness of the upper web plate 3 and the lower web plate 4 and the middle web plate 5 are respectively thicker than the thickness of their respective outer edges. The front axle body 1, the upper web plate 3, the lower web plate 4 and the middle web plate 5 are integrally formed. The wavelength of the wave-shaped structure of the middle web plate 5 is 26.67 times the wave height. The thickness of the lower web plate 4 is greater than that of the upper web plate 3.
[0015] The working principle of this utility model is as follows: The structural design of this utility model is more reasonable. By reducing the thickness of the upper web of the I-beam, the width of the upper and lower webs of the I-beam, and the thickness of the middle web, the cross-sectional area of the I-beam is reduced by 29.5% compared to the circular tube beam, thus achieving a 12.5% weight reduction in the front axle. In addition, the height of its I-beam cross-section is higher than that of the circular tube beam, which improves the bending fatigue strength of the front axle. The middle web is designed in a wave shape to improve the bending deformation stiffness of the front axle. That is, while reducing the overall weight, it can also improve the bending resistance of the front axle.
[0016] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
