[0022] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0023] Reference below Figure 1-Figure 2 An air chamber bracket assembly according to an embodiment of the present utility model is described.

[0024] like Figure 1-Figure 2 As shown, the air chamber bracket assembly includes: an air chamber bracket, an axle tube 5 and a first bracket 4.

[0025] The air chamber bracket is rotatably sleeved on the shaft tube 5, the first bracket 4 is fixedly sleeved on the shaft tube 5, the air chamber bracket is arranged at one end of the first bracket 4 along the axial direction of the shaft tube 5, and is connected to the first bracket 4 through a connecting assembly.

[0026] Specifically, the air chamber bracket is rotated to adjust the air chamber bracket to a suitable position, and then the air chamber bracket is fixedly connected to the first bracket 4 using a connecting assembly, so as to realize air chamber brackets of different sizes and angles to meet different product requirements. At the same time, air chamber brackets of different sizes and angles can also be realized by replacing air chamber brackets of different specifications. In addition, the air chamber bracket, the shaft tube 5, and the first bracket 4 are split and designed, and any component can be replaced according to different product requirements, which is highly flexible, realizes universal design, and is convenient for maintenance and replacement.

[0027] Therefore, according to the air chamber bracket assembly of the utility model, the angle of the air chamber bracket can be adjusted by rotating the air chamber bracket or replacing the air chamber bracket of different specifications, so as to realize air chamber brackets of different sizes and angles, which can meet the different needs of the whole vehicle. In addition, the air chamber bracket, the shaft tube 5, and the first bracket 4 are split and designed to realize universal interchangeability. At the same time, the parts manufacturer can greatly reduce the investment in molds and the backlog of parts, thereby reducing costs.

[0028] According to some specific embodiments of the utility model, see Figure 2 As shown, the first bracket 4 is formed with a plurality of circumferentially arranged first mounting holes on the outer periphery along the radial direction of the shaft tube 5, and the air chamber bracket is formed with a plurality of second mounting holes 201 corresponding to the first mounting holes one by one, and the connecting assembly passes through the first mounting holes and the second mounting holes 201 to fix the first bracket 4 and the air chamber bracket in connection.

[0029] In this way, multiple first mounting holes and multiple second mounting holes 201 correspond one to one, and the air chamber bracket is rotated. The angle of the air chamber bracket is adjusted by selecting first mounting holes at different angles on the first bracket 4, and then the connecting component is used to pass through the first mounting hole and the second mounting hole 201 to fix the air chamber bracket to the first bracket 4, thereby realizing air chamber brackets of different sizes and angles to meet the different needs of the whole vehicle.

[0030] In some embodiments of the present invention, the first bracket 4 may be a flange.

[0031] According to some specific embodiments of the utility model, see Figure 1 As shown, the connection assembly includes a bolt 7 and a nut, and the bolt 7 passes through the first mounting hole and the second mounting hole 201 and is threadedly connected with the nut.

[0032] With such arrangement, after the bolt 7 passes through the first mounting hole and the second mounting hole 201 , the bolt 7 is threadedly connected with the nut, thereby fixing the air chamber bracket to the first bracket 4 , which is simple to operate and convenient to install.

[0033] According to some specific embodiments of the utility model, see Figure 2 A first through hole for passing the shaft tube 5 is formed on the first bracket 4, and a plurality of first mounting holes are arranged equidistantly around the outer circumference of the first through hole, and an angle α is formed by a line connecting the centers of two adjacent first mounting holes and the centers of the first through holes, and α satisfies the relationship: 90°≥α≥20°.

[0034] With such a configuration, the angle α ranges from 20° to 90°, that is, the number of first mounting holes of the first bracket 4 ranges from 4 to 18. Correspondingly, the air chamber bracket can be adjusted to 4 to 18 angles. By rotating the air chamber bracket and selecting first mounting holes at different angles to adjust the angle of the air chamber bracket, air chamber brackets of different sizes and angles can be realized to meet the different needs of the vehicle. If the angle α is too small, the number of first mounting holes is too large, resulting in slow assembly efficiency; if the angle α is too large, the range of first mounting holes of different angles selected by the air chamber bracket is small, resulting in a small number of adjustable angles of the air chamber bracket and low practicality.

[0035] In some embodiments, the angle α is 45°. Thus, the air chamber support has eight adjustment angles.

[0036] In some embodiments, see Figure 2 , the angle is 60°. In this way, the air chamber bracket has six adjustment angles.

[0037] According to some specific embodiments of the utility model, the air chamber bracket includes: a connected air chamber connecting plate 1 and a bracket connecting plate 2, the air chamber connecting plate 1 is formed with an air chamber mounting hole 101, the bracket connecting plate 2 is formed with a second through hole for passing the sleeve shaft tube 5, and the bracket connecting plate 2 is formed with a plurality of equidistantly arranged second mounting holes 201 around the periphery of the second through hole.

[0038] In this arrangement, the air chamber is fixedly mounted on the air chamber connecting plate 1 through the air chamber mounting hole 101, and the bracket connecting plate 2 is rotatably sleeved on the shaft tube 5 through the second through hole. The air chamber connecting plate 1 and the bracket connecting plate 2 can be an integral stamping part with high strength and convenient for manufacturing and installation. Figure 1 As shown, the air chamber connecting plate 1 and the bracket connecting plate 2 are located in different planes, and the planes where the two are located are perpendicular to each other, which is conducive to installing the air chamber and ensuring the installation strength of the air chamber.

[0039] According to some specific embodiments of the utility model, a first reinforcing rib 8 is provided between the air chamber connecting plate 1 and the bracket connecting plate 2 ; and / or a second reinforcing rib is provided between the first bracket 4 and the shaft tube 5 .

[0040] With this setting, see Figure 2 A first reinforcing rib 8 is provided between the air chamber connecting plate 1 and the bracket connecting plate 2 to improve the strength and rigidity of the air chamber bracket, thereby improving the installation strength of the air chamber. In addition, a second reinforcing rib is provided between the first bracket 4 and the shaft tube 5 to improve the connection strength between the first bracket 4 and the shaft tube 5, thereby improving the connection strength between the air chamber bracket and the shaft tube 5.

[0041] According to some specific embodiments of the utility model, it also includes: an adjustment arm bracket 3, the adjustment arm bracket 3 and the air chamber bracket are an integrally formed part, the adjustment arm bracket 3 is sleeved on the shaft tube 5, and is fixedly connected to the shaft tube 5.

[0042] In this way, the adjusting arm bracket 3 is used to install the adjusting arm, and the adjusting arm bracket 3 and the air chamber bracket are formed as an integral part. When the air chamber bracket rotates, the adjusting arm bracket 3 is driven to rotate on the shaft tube 5. When rotated to a suitable position, the adjusting arm bracket 3 is fixedly connected to the shaft tube 5, so as to adapt to different product requirements.

[0043] Of course, the adjustment arm bracket 3 and the air chamber bracket can be designed separately, and the adjustment arm bracket 3 can be rotatably sleeved on the shaft tube 5, and when rotated to a suitable position, it is fixedly connected with the shaft tube 5. For example, welding can be used for fixed connection.

[0044] According to some specific embodiments of the utility model, it also includes: a second bracket 6, which is fixedly sleeved on the shaft tube 5 and spaced apart at the other end of the first bracket 4 along the axial direction of the shaft tube 5, and a brake mounting hole is formed on the second bracket 6.

[0045] In this arrangement, the second bracket 6 is used to install the brake, and the second bracket 6 is fixedly sleeved on the shaft tube 5 and spaced apart from the first bracket 4 to prevent interference when installing the actuator.

[0046] According to some specific embodiments of the utility model, see Figure 1 As shown, the first bracket 4 and / or the second bracket 6 are fixed to the outer circumferential surface of the shaft tube 5 by welding.

[0047] With such arrangement, the first bracket 4 can be fixed to the outer circumference of the shaft tube 5 by welding. Similarly, the second bracket 6 can also be fixed to the outer circumference of the shaft tube 5 by welding, thereby ensuring the connection strength between the first bracket 4 and the second bracket 6 and the shaft tube 5, thereby ensuring the connection strength between the first bracket 4 and the air chamber bracket, and the connection between the second bracket 6 and the actuator.

[0048] Furthermore, a third bracket, a fourth bracket, etc. may be provided on the shaft tube 5 for installing relevant functional components.

[0049] A vehicle according to an embodiment of the second aspect of the utility model includes: an air chamber bracket assembly.

[0050] Therefore, the present application splits the integral cast iron air chamber bracket into several independent components, such as the air chamber bracket, the first bracket 4, the second bracket 6, the axle tube 5, the adjustment arm bracket 3, etc. On the one hand, universal interchangeability is achieved by replacing some parts, which has high flexibility, realizes universal design, and is convenient for maintenance and replacement; on the other hand, by rotating the air chamber bracket to select the first mounting hole at different angles to adjust the angle of the air chamber bracket, or by replacing air chamber brackets of different specifications to adjust the angle of the air chamber bracket, air chamber brackets of different sizes and angles can be achieved to meet the different needs of the whole vehicle; on the third hand, parts manufacturers can greatly reduce the investment in molds and the backlog of parts, thereby reducing costs.
