Description

Technical Field

[0001] The utility model relates to the technical field of commercial vehicle front axles, in particular to a lightweight front axle of a commercial vehicle. Background Art

[0002] The front axle of a car is an important load-bearing component. Currently, the structure of the front axle of commercial vehicles has not changed much, such as Figure 5 The front axle of the commercial vehicle in the prior art shown has a wheel design center axis on the front axle body that is higher than the leaf spring mounting surface, and a lower wing surface in the middle part of the front axle body that is lower than the lower wing surface of the leaf spring seat, resulting in a bloated mass and low passability of the commercial vehicle front axle. As commercial vehicles become lighter, the requirements for comfort and high passability are getting higher and higher, and it is necessary to optimize the existing commercial vehicle front axle structure to meet the requirements of high passability and lightweight. Summary of the invention

[0003] The utility model aims to provide a commercial vehicle front axle with simple structure, light weight and good trafficability.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a lightweight front axle of a commercial vehicle, comprising a front axle body, a leaf spring mounting surface, an upper wing surface, and a lower wing surface; the design center axis of the wheel on the front axle body is located 0-50 mm below the leaf spring mounting surface, and a plurality of lightweight process holes are evenly distributed between the upper wing surface and the lower wing surface of the front axle body.

[0005] Furthermore, the lower wing surfaces of the front axle body are located in the same horizontal plane.

[0006] Furthermore, there are two lightweight process holes evenly distributed between the upper wing surface and the lower wing surface of the front axle body, which are respectively located between the upper wing surface and the lower wing surface below the leaf spring mounting surface.

[0007] Beneficial effects of the utility model: Compared with the prior art, the utility model provides a commercial vehicle front axle with a simple structure, light weight and good passability. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0015] like Figures 1 to 4 As shown, a lightweight front axle for a commercial vehicle comprises a front axle body 2, a leaf spring mounting surface 3, an upper wing surface 4, and a lower wing surface 5; a wheel design center axis 1 on the front axle body 2 is located 0-50 mm below the leaf spring mounting surface 3, and a plurality of lightweight process holes 6 are evenly distributed between the upper wing surface 4 and the lower wing surface 5 of the front axle body 2;

[0016] In this implementation scheme, the actual optimal solution selects a wheel whose design center axis 1 is located 50 mm below the leaf spring mounting surface 3. Compared with the existing commercial vehicle front axle wheel whose design center axis 1 is located about 200 mm above the leaf spring mounting surface 3, this implementation scheme saves about 250 mm of material in the height direction at both ends of the commercial vehicle front axle, which has a significant effect on the lightweighting of the commercial vehicle front axle.

[0017] like Figure 1 As shown, the lower wing surface 5 of the front axle body 2 is located in the same horizontal plane;

[0018] In this embodiment, compared with the existing structure in which the lower wing surface of the middle part of the front axle body of a commercial vehicle is lower than the lower wing surface of the leaf spring seat, this embodiment significantly improves the passing performance of the front axle of the commercial vehicle.

[0019] like Figure 1 As shown, there are two lightweight process holes 6 evenly distributed between the upper wing surface 4 and the lower wing surface 5 of the front axle body 2, which are respectively located between the upper wing surface 4 and the lower wing surface 5 below the leaf spring mounting surface 3;

[0020] In the present embodiment, the position below the leaf spring mounting surface 3 is the position on the front axle body 2 with the best strength and the least influence of various alternating loads and stresses, and is suitable for arranging the lightweight process hole 6 .

[0021] The specific working principle of this utility model:

[0022] The utility model discloses a lightweight front axle for a commercial vehicle, and aims to provide a front axle for a commercial vehicle with simple structure, light weight and good trafficability.

[0023] First, the wheel design center axis 1 on the front axle body 2 is designed to be 0-50 mm below the leaf spring installation surface 3; compared with the existing commercial vehicle front axle wheel design center axis 1 is located above the leaf spring installation surface 3, this embodiment saves a corresponding length of material in the height direction of both ends of the commercial vehicle front axle, and has a significant effect on the lightweighting of the commercial vehicle front axle;

[0024] Then, the lower wing surface 5 of the front axle body 2 is designed to be located at the same horizontal plane. Compared with the existing structure in which the lower wing surface of the middle part of the front axle body of a commercial vehicle is lower than the lower wing surface of the leaf spring seat, this embodiment significantly improves the passing performance of the front axle of the commercial vehicle;

[0025] Finally, a lightweight process hole 6 is arranged between the upper wing surface 4 and the lower wing surface 5 below the two leaf spring mounting surfaces 3; below the leaf spring mounting surface 3 is the position on the front axle body 2 with the best strength and the least influence of various alternating loads and stresses, which is suitable for arranging the lightweight process hole 6.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any simple modification, equivalent replacement, improvement, etc. made within the technical concept of the present invention should be included in the protection scope of the present invention.
