Description

Technical Field

[0001] The present invention relates to the technical field, and in particular to an air storage tank for an air suspension system and processing equipment thereof. Background Art

[0002] Air tanks are often used in automobile air suspension systems, especially for four-point air suspensions. The main function of the air tank is to quickly and timely fill the high-pressure gas stored in it into the air spring, so that the air spring can reach the required height and air pressure in a relatively short time.

[0003] At present, lightweighting of parts is an important design goal of automobile manufacturers, especially for new energy vehicles. High pressure resistance is also an important indicator of gas tank performance requirements. Therefore, lightweighting and high pressure resistance together become important tasks in gas tank design.

[0004] The existing solution is to use aluminum stamping and welding technology. Aluminum gas tanks can be lightweight, but ordinary welding (such as carbon dioxide shielded welding or argon arc welding, etc.) after stamping will affect the strength of the gas tank. Many automobile manufacturers want to use the "aluminum blowing process" to avoid the adverse effects of ordinary welding, but there are currently few "aluminum blowing process" production equipment and capabilities in China, so the processing is relatively difficult. Summary of the invention

[0005] Based on the technical problems existing in the background technology, the present invention proposes an air storage tank for an air suspension system.

[0006] The present invention proposes an air storage tank for an air suspension system, wherein the air storage tank body consists of a symmetrical first half and a second half, both of which are rotationally symmetrical structures; a first step flange is provided at the open end of the first half, and a second step flange is provided at the open end of the second half, and the first step flange and the second step flange are symmetrical; the first step flange and the second step flange are friction welded.

[0007] Preferably, two circles of reinforcing ribs are coaxially arranged on the first half, and at least one limit bar parallel to the axial direction of the gas storage tank is provided between the two circles of reinforcing ribs.

[0008] Preferably, a plurality of limit bars are provided between the two circles of reinforcement ribs on the first half and are evenly distributed in a ring shape.

[0009] Preferably, the diameter of the circumscribed circle of the plurality of limit bars is smaller than the diameter of the circumscribed circle of the reinforcing ribs.

[0010] Preferably, a plurality of limit levers form a gear structure.

[0011] Preferably, the second half is provided with two circles of reinforcing ribs and at least one limiting bar, and is symmetrical to the reinforcing ribs and limiting bar on the first half.

[0012] A processing device for an air storage tank for an air suspension system is used to clamp the air storage tank; the processing device includes an air storage tank clamping arm; the air storage tank clamping arm is provided with an annular clamping claw that matches two circles of reinforcing ribs in a closed state, and a limiting protrusion that matches the limiting bar is provided inside the annular clamping claw.

[0013] Preferably, a plurality of limiting protrusions are provided on the inner circumference of the annular clamping jaw to form a gear structure.

[0014] Preferably, the processing equipment comprises gas tank clamping arms for clamping the first half and the second half respectively, and one of the gas tank clamping arms is rotatably mounted.

[0015] The present invention proposes an air storage tank for an air suspension system. The arrangement of a first step flange and a second step flange increases the welding area of ​​the first half and the second half. The first step flange and the second step flange are welded by a rotational friction method, which increases the welding lightness and avoids additional welding materials, thereby further ensuring the lightweight of the air storage tank.

[0016] In the present invention, two circles of reinforcing ribs are used to isolate the clamping jaw from the first step flange, thereby reducing the thermal conductivity of the first step flange to the clamping jaw, and the reinforcing ribs between the first step flange and the clamping jaw increase the heat retention rate of the first step flange, thereby further improving the efficiency of rotary friction welding.

[0022] Reference Figure 1The present invention provides an air storage tank for an air suspension system, wherein the air storage tank body is composed of a symmetrical first half 1 and a second half 2, both of which are rotationally symmetrical structures. A first step flange 3 is provided at the open end of the first half 1, and a second step flange 4 is provided at the open end of the second half 2, and the first step flange 3 and the second step flange 4 are symmetrical. The first step flange 3 and the second step flange 4 are friction welded.

[0023] The provision of the first step flange 3 and the second step flange 4 increases the welding area of ​​the first half 1 and the second half 2. The first step flange 3 and the second step flange 4 are welded by a rotational friction method, which increases the welding lightness and avoids additional welding materials, thereby further ensuring the lightweight of the gas tank.

[0024] In this embodiment, two circles of reinforcing ribs 5 are coaxially arranged on the first half 1, and at least one limit bar 6 parallel to the axis direction of the gas tank is arranged between the two circles of reinforcing ribs 5. In this way, by setting the reinforcing ribs 5, it is possible to avoid the generation of defective products due to the movement of the clamping jaws along the axis direction of the gas tank during the rotational friction welding process; by setting the limit bar 6, it is possible to avoid the relative rotation between the clamping jaws and the first half 1 during the rotational friction welding process, thereby ensuring the effectiveness of the relative rotation between the first half 1 and the second half 2.

[0025] At the same time, in this embodiment, the two circles of reinforcing ribs 5 are used to isolate the clamping jaws from the first step flange 3, thereby reducing the thermal conductivity of the first step flange 3 to the clamping jaws, and the reinforcing ribs 5 between the first step flange 3 and the clamping jaws improve the heat retention rate of the first step flange 3, thereby further improving the efficiency of the rotary friction welding. In this embodiment, a plurality of limiting bars 6 are arranged between the two circles of reinforcing ribs 5 on the first half 1 and are evenly distributed in a ring shape. Moreover, the diameter of the circumscribed circle of the plurality of limiting bars 6 is smaller than the diameter of the circumscribed circle of the reinforcing ribs 5 to ensure the limiting effect of the reinforcing ribs 5 on the clamping jaws. In this embodiment, the plurality of limiting bars 6 form a gear structure.

[0026] In this embodiment, two circles of reinforcing ribs 5 and at least one limit bar 6 are provided on the second half 2, and are symmetrical with the reinforcing ribs 5 and the limit bar 6 on the first half 1, so as to ensure that the second half 2 is clamped and fixed by the clamp during the rotational friction welding process; or the first half 1 and the second half 2 can be further rotated in opposite directions at the same time through the clamping of the clamp, thereby further improving the welding efficiency.

[0027] The present invention also proposes a processing device for an air storage tank for an air suspension system, which is used to clamp the above-mentioned air storage tank; the processing device includes an air storage tank clamping arm; the air storage tank clamping arm is provided with an annular clamping claw 7 that matches with two circles of reinforcing ribs 5 in a closed state, and a limiting protrusion 8 that matches with the limiting lever 6 is provided inside the annular clamping claw 7. In this way, when the clamping claw clamps the first half 1 or the second half 2, the reinforcing rib 5 limits the annular clamping claw 7 axially, and the limiting lever 6 cooperates with the limiting protrusion 8 to limit the annular clamping claw 7 in the circumferential direction.

[0028] Specifically, in the present embodiment, a plurality of limiting protrusions 8 are provided on the inner circumference of the annular clamping jaw 7 to form a gear structure, so as to facilitate the meshing of the gear structure formed by the limiting lever 6 .

[0029] In this embodiment, the processing equipment includes gas tank clamping arms for clamping the first half 1 and the second half 2, respectively, and one of the gas tank clamping arms is rotatably installed to achieve relative rotation of the first half 1 and the second half 2. Moreover, by fixing one of the gas tank clamping arms, the second half 2 is stationary, which is conducive to reducing the error caused by relative movement.

[0030] The above description is only a preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
