Description

Technical Field

[0001] The utility model relates to a swing arm assembly, more specifically to an aluminum alloy swing arm assembly structure. Background Art

[0002] The automobile swing arm assembly is a fastener that connects the wheel assembly and the body to ensure the driving safety of the vehicle. During the driving process of the vehicle, the front suspension is mainly a guide rod, and it also acts as a thrust rod to withstand the longitudinal, lateral forces and moments during braking, starting and steering.

[0003] The materials of the integral swing arm assembly in the prior art are quite diverse, including aluminum alloy, cast iron, multi-layer stamping parts, single-layer stamping parts, etc.; the following technical problems exist: due to the limitations of processing technology and forming materials, the structure is complex, the unsprung weight is large, and it is easy to rust and fatigue crack. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide an aluminum alloy swing arm assembly structure, which can solve the above-mentioned problems.

[0005] To solve the above technical problems, according to one aspect of the utility model, more specifically, an aluminum alloy swing arm assembly structure includes an aluminum alloy swing arm body, front swing arm front bushings are integrally formed on both sides of the aluminum alloy swing arm body, a front swing arm rear bushing assembly is integrally formed on the outer side wall of the front swing arm front bushing, and a shock absorber bushing assembly is integrally formed on the front side of the aluminum alloy swing arm body.

[0006] Furthermore, a hollow hole is provided on the upper surface of the aluminum alloy swing arm body.

[0007] Furthermore, weight-reducing grooves are symmetrically provided on the upper surface and the lower surface of the aluminum alloy swing arm body.

[0008] The beneficial effects of the aluminum alloy swing arm assembly structure of the utility model are:

[0009] The two front bushings of the front swing arm are used to install the frame, and the shock absorber bushing assembly is used to install and fix the shock absorber. The aluminum alloy swing arm body is made of an aluminum alloy tube, and a hollow hole and a weight-reducing groove are opened in the middle thereof, so as to achieve a more excellent lightweight design compared with the traditional steel structure design of the same volume, and there is no rust problem, which is more in line with the future lightweight design of automobile chassis;

[0010] By setting up a process of pressing the shock absorber bushing, the front bushing of the front swing arm and the rear bushing of the front swing arm after the aluminum alloy body swing arm is integrally cast, the manufacturing is simpler and more efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The utility model is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0012] Figure 1 This is a schematic diagram of the overall structure of an aluminum alloy swing arm assembly structure of the utility model;

[0013] Figure 2 This is a stress cloud diagram of an aluminum alloy swing arm assembly structure of the utility model.

[0014] In the figure: 1. Front bushing of front swing arm; 2. Aluminum alloy swing arm body; 3. Front swing arm rear bushing assembly; 4. Shock absorber bushing assembly; 5. Hollow hole; 6. Weight reduction groove. DETAILED DESCRIPTION

[0015] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0016] According to one aspect of the present invention, Figure 1 As shown in FIG. 2 , an aluminum alloy swing arm assembly structure is provided, including an aluminum alloy swing arm body 2, front swing arm front bushings 1 are integrally formed on both sides of the aluminum alloy swing arm body 2, a front swing arm rear bushing assembly 3 is integrally formed on the outer side wall of the front swing arm front bushing 1, and a shock absorber bushing assembly 4 is integrally formed on the front side of the aluminum alloy swing arm body 2. After the aluminum alloy swing arm body 2 is integrally cast, the front swing arm front bushing 1, the front swing arm rear bushing assembly 3 and the shock absorber bushing assembly 4 are manufactured by a press-fit bushing process.

[0017] In this embodiment, a hollow hole 5 is opened on the upper surface of the aluminum alloy swing arm body 2 to reduce weight.

[0018] In this embodiment, weight-reducing grooves 6 are symmetrically provided on the upper and lower surfaces of the aluminum alloy swing arm body 2 to further reduce the weight.

[0019] The working principle of the device is: the existing vehicle frame and two front swing arm front bushings 1 are installed and fixed, and then the existing shock absorber and shock absorber bushing assembly 4 are installed and fixed.

[0020] The electrical components that appear in this article are all electrical components that exist in reality.

[0021] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention also fall within the protection scope of the present invention.
