[0030] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-4 Description of a tube bundle support 100 according to a first aspect embodiment of the present invention.

[0031] like Figures 1-3 As shown, the tube bundle support 100 according to the first aspect embodiment of the present invention includes: a connecting part 11, a first fixing part 12, and a second fixing part 13.

[0032] Specifically, the connecting portion 11 is adapted to be connected to the frame 31. A first fixing portion 12 is provided in the width direction of the connecting portion 11 (e.g., Figure 1 On one side of the connecting portion 11 (in the vertical direction), the first fixing part 12 extends in a direction away from the connecting part 11. The second fixing part 13 is provided on the other side of the connecting portion 11 in the width direction, and the second fixing part 13 extends in a direction away from the connecting part 11.

[0033] The first fixing part 12 and / or the second fixing part 13 are provided with fixing grooves 14, and the second fixing part 13 is arc-shaped.

[0034] For example, in the example shown in the figure, after the connecting part 11 is connected to the frame 31, the width direction of the connecting part 11 is parallel to the travel direction of the vehicle 300 (e.g., Figure 3 The left and right directions are consistent, and the length direction of the connecting part 11 (for example, ...) is consistent. Figure 1 (in the left and right directions) and the width direction of vehicle 300 (e.g., Figure 3 The vertical direction is consistent. A fixing groove 14 is formed on both the first fixing part 12 and the second fixing part 13. The fixing groove 14 on the first fixing part 12 is used to fix the tube bundle 21 of the middle axle 32 air chamber, and the fixing groove 14 on the second fixing part 13 is used to fix the tube bundle 21 of the rear axle 33 air chamber. Alternatively, a fixing groove 14 may be formed only on the first fixing part 12 (not shown in the figure); or, a fixing groove 14 may be formed only on the second fixing part 13 (not shown in the figure).

[0035] In practical implementation, the connecting part 11 is connected to the balance shaft crossbeam 311 of the frame 31, providing a stable mounting base for the first fixing part 12 and the second fixing part 13. This provides a reliable support point for the tube bundle 21 of the middle axle 32 air chamber or the rear axle 33 air chamber, preventing the tube bundle 21 from shaking due to lack of fixation during vehicle 300 operation. Furthermore, the first fixing part 12 and the second fixing part 13 are respectively located on both sides of the connecting part 11 in the width direction, and are used to fix the tube bundle 21 of the middle axle 32 air chamber and the rear axle 33 air chamber, respectively. This reduces the probability of contact and interference wear between the tube bundle 21 and the through hole 3111 of the balance shaft crossbeam 311, ensuring the safety of the vehicle 300's braking system. Furthermore, the first fixing part 12 and the second fixing part 13 extend in a direction away from the connecting part 11, making the first fixing part 12 and the second fixing part 13 closer to the air chamber of the middle axle 32 and the air chamber of the rear axle 33. This provides more installation space for the tube bundle 21 in the air chambers of the middle axle 32 and the rear axle 33, improving the feasibility of the tube bundle 21 arrangement. In addition, due to the complex structure and limited space of the frame 31, the shape of the second fixing part 13 is designed to be arc-shaped, which fully adapts to the shape and spatial position of the frame 31. This allows the tube bundle 21 and the tube bundle bracket 100 to avoid interference from other components on the frame 31, thereby improving the applicability of the tube bundle bracket 100.

[0036] According to the embodiment of the present invention, the tube bundle bracket 100 is connected to the vehicle frame 31 through the connecting part 11, and a fixing groove 14 is formed on the first fixing part 12 and the second fixing part 13, which provides a reliable support point for the tube bundle 21 of the middle axle 32 air chamber or the rear axle 33 air chamber, reduces the probability of contact and interference wear between the tube bundle 21 and the through hole 3111 of the balance shaft crossbeam 311, ensures the safety of the braking system of the vehicle 300, and provides more installation space for the tube bundle 21 of the middle axle 32 air chamber and the rear axle 33 air chamber, improves the feasibility of tube bundle 21 arrangement, and the tube bundle bracket 100 has high applicability.

[0037] According to some embodiments of the present invention, the second fixing part 13 includes a first fixing segment 131 and a second fixing segment 132, wherein the first fixing segment 131 and the second fixing segment 132 are along the length direction of the connecting part 11 (e.g., Figure 1 Arranged in the left-right direction. Along the direction away from the first fixing part 12, the minimum distance between the first fixing segment 131 and the second fixing segment 132 in the length direction of the connecting part 11 gradually increases.

[0038] For example, in Figure 1In the example, the first fixed segment 131 and the second fixed segment 132 are both arc-shaped, and the first fixed segment 131 and the second fixed segment 132 are symmetrically distributed on both sides of the length direction of the connecting part 11, respectively corresponding to the left and right rear axle 33 air chambers. This achieves precise positioning and fixing of the tube bundle 21 of the left and right rear axle 33 air chambers, making the connection between the rear axle 33 air chambers and the tube bundle 21 more regular and orderly, improving the compactness and rationality of the tube bundle 21 layout, and making it easier for maintenance personnel to inspect and repair the tube bundle 21 of a certain air chamber, thus improving the convenience of later maintenance.

[0039] Furthermore, the minimum distance between the first fixing segment 131 and the second fixing segment 132 along the length of the connecting portion 11 gradually increases, allowing the first fixing segment 131 and the second fixing segment 132 to match the positions of the left and right rear axle 33 air chambers respectively. This enables a more reasonable fixation of the air chamber tube bundle 21. Moreover, this arrangement allows the first fixing segment 131 and the second fixing segment 132 to better conform to the direction of the tube bundle 21, providing support and fixation that more closely follows the actual path. This ensures that the tube bundle 21 maintains a stable position during vehicle 300 operation, reducing the risk of interference between the tube bundle 21 and other components. In addition, the arrangement of the first fixing segment 131 and the second fixing segment 132 shortens the length of the tube bundle 21, reducing the cost of the tube bundle.

[0040] It should be noted that the tube bundle 21 is fixed to the tube bundle support 100 by fasteners such as cable ties, and this application does not impose specific restrictions on this.

[0041] Furthermore, the included angle between the first fixed segment 131 and the second fixed segment 132 is α, where α satisfies: 90° ≤ α < 180°.

[0042] When α < 90°, the angle between the first fixed section 131 and the second fixed section 132 is too small, meaning the first fixed section 131 and the second fixed section 132 are relatively close. The tube bundle 21 needs to be excessively bent or twisted to adapt to the positions of the first fixed section 131 and the second fixed section 132, which increases the difficulty of installing the tube bundle 21. It may also cause the tube bundle 21 to affect the transmission speed of air pressure inside the tube bundle 21 due to excessive bending during use. Furthermore, it may cause the tube bundle 21 to be damaged due to excessive bending during use, reducing the service life of the tube bundle 21 and affecting the normal operation of the braking system. When α > 180°, the angle between the first fixed section 131 and the second fixed section 132 is too large, meaning the distance between the first fixed section 131 and the second fixed section 132 is too far, which may occupy too much space near the rear axle 33. Furthermore, this can cause positional interference with other components within the frame 31, affecting the overall rational layout of the vehicle. Moreover, the first fixed section 131 and the second fixed section 132 cannot conform to the actual path of the tube bundle 21, which may result in uneven distribution of the fixing force on the air chamber tube bundle 21. This makes it impossible to provide stable support and constraint for the tube bundle 21, reducing the fixing stability of the air chamber tube bundle 21 and increasing the risk of interference and wear between the tube bundle 21 and the through hole 3111 of the balance shaft beam 311, thus affecting the reliability of the braking system.

[0043] Therefore, by setting the included angle α between the first fixed section 131 and the second fixed section 132 within the range of 90° ≤ α < 180°, the difficulty of installing the tube bundle 21 is reduced, the normal operation of the braking system is ensured, and the overall layout of the vehicle is improved. The first fixed section 131 and the second fixed section 132 are aligned with the actual path of the tube bundle 21, providing stable support and constraint for the tube bundle 21. This improves the fixing stability of the air chamber tube bundle 21, reduces the risk of interference and wear between the tube bundle 21 and the through hole 3111 of the balance shaft beam 311, ensures the reliability of the braking system, and improves the service life of the tube bundle 21.

[0044] According to some embodiments of the present invention, the first fixing part 12 is located between the first fixing segment 131 and the second fixing segment 132 in the length direction of the connecting part 11.

[0045] For example, in Figure 1In the example, the first fixing part 12 is an elongated strip-shaped structure. The length direction of the first fixing part 12 is consistent with the driving direction of the vehicle 300, which can guide the tube bundle 21. After the tube bundle 21 is fixed to the first fixing section 131 and the second fixing section 132, it continues to extend towards the first fixing part 12 and is further fixed on the first fixing part 12. The first fixing part 12 is located between the first fixing section 131 and the second fixing section 132, which makes the pressure transmission of the tube bundle 21 in the left and right air chambers smoother and more balanced, ensuring the consistency of pressure changes in the left and right rear axle 33 air chambers during braking, thereby improving the stability of braking and avoiding phenomena such as vehicle 300 veering during braking.

[0046] In some optional embodiments, the connecting portion 11 includes: a first connecting segment 111 and two second connecting segments 112, wherein the first fixing portion 12 and the second fixing portion 13 are respectively disposed in the width direction of the first connecting segment 111 (e.g., Figure 1 The two second connecting segments 112 are respectively located on both sides of the length direction of the first connecting segment 111 (e.g., in the vertical direction). Figure 1 On both sides of the left and right direction of the first connecting segment 111, each second connecting segment 112 is along the thickness direction of the first connecting segment 111 (e.g., in the left and right direction). Figure 2 Extending in the vertical direction, each second connecting segment 112 is adapted to connect to the frame 31.

[0047] This configuration provides a reliable connection foundation for the entire tube bundle support 100. Two second connecting sections 112 are respectively positioned on either side of the length of the first connecting section 111 and extend along its thickness to connect with the frame 31. This increases the contact area between the connecting section 11 and the frame 31, allowing the force from the tube bundle 21 to be transferred to the frame 31. This improves the connection reliability between the tube bundle support 100 and the frame 31, making it more stable under external forces and less prone to loosening. Furthermore, the positional distribution of the first fixing part 12 and the second fixing part 13 of the first connecting section 111 and the two second connecting sections 112 fully utilizes the space around the frame 31. The second connecting section 112 extending along the thickness of the first connecting section 111 avoids positional interference with other components on the frame 31, making the installation of the tube bundle support 100 on the frame 31 more compact and facilitating the lightweight design of the tube bundle support 100.

[0048] In some alternative embodiments, the second fixing part 13 is inclined along the thickness direction of the first connecting section 111 and extends away from the second connecting section 112. Since the rear axle 33 air chamber is not in the same horizontal direction as the balance shaft of the frame 31, the inclined second fixing part 13 can more accurately fit the tube bundle 21 of the rear axle 33 air chamber, making the fixing of the tube bundle 21 smoother, reducing stress concentration caused by excessive bending or twisting of the tube bundle 21 and reducing wear on the tube bundle 21, thus improving the service life of the tube bundle 21. Moreover, the inclined second fixing part 13 fits the tube bundle 21 of the rear axle 33 air chamber, making the force support of the second fixing part 13 on the tube bundle 21 more reasonable, thereby effectively decomposing the force from the tube bundle 21 into component forces along the connecting part 11 in various directions, so that the force can be transmitted to the frame 31 more evenly through the connecting part 11, thereby enhancing the stability and load-bearing capacity of the entire tube bundle support 100.

[0049] Further, each second connecting segment 112 includes: a first sub-connecting segment 1121 and a second sub-connecting segment 1122. The first sub-connecting segment 1121 is connected to the first connecting segment 111 and extends along the thickness direction of the first connecting segment 111. The second sub-connecting segment 1122 is located on the side of the first sub-connecting segment 1121 away from the first connecting segment 111, and extends along the length direction of the first connecting segment 111 in a direction away from the first connecting segment 111. A fixing hole 1123 is formed on the second sub-connecting segment 1122, and the shapes of the fixing holes 1123 on the two second sub-connecting segments 1122 are different.

[0050] For example, in Figure 1 In the example, the fixing hole 1123 on one of the second sub-connecting segments 1122 can be circular, while the fixing hole 1123 on the other second sub-connecting segment 1122 can be oblong. This application does not impose specific limitations on this. The fixing holes 1123 of different shapes can be matched with the corresponding mounting points on the frame 31, thereby ensuring that the mounting position of the connecting part 11 on the frame 31 is accurate, playing a role in preventing incorrect installation on the production line, and improving the accuracy and reliability of installation.

[0051] Furthermore, the first sub-connecting segment 1121 provides a foundation for the second sub-connecting segment 1122 to connect with the first connecting segment 111, ensuring a stable connection between the second sub-connecting segment 1122 and the first connecting segment 111. Moreover, the second sub-connecting segment 1122 extends away from the first connecting segment 111 along the length direction of the first connecting segment 111, that is, one side surface of the second sub-connecting segment 1122 in the length direction of the first connecting segment 111 is in contact with the balance shaft beam 311, which increases the contact area between the tube bundle support 100 and the balance shaft beam 311 of the frame 31, and improves the firmness of the connection between the entire connecting part 11 and the frame 31, thereby ensuring the operational reliability of the tube bundle support 100.

[0052] Furthermore, in the width direction of the first connecting segment 111, the second sub-connecting segment 1122 is provided on the side of the first sub-connecting segment 1121 adjacent to the first fixing part 12.

[0053] In specific implementation, the connecting part 11 and the second fixing part 13 are located between the balance shaft crossbeam 311 and the air chamber of the rear axle 33, and the first fixing part 12 is located between the balance shaft crossbeam 311 and the air chamber of the middle axle 32. After the second sub-connecting section 1122 is fixed to the balance shaft crossbeam 311, since the first fixing part 12 is located on the side of the first sub-connecting section 1121 adjacent to the second sub-connecting section 1122, the first fixing part 12 is more convenient to pass through the through hole 3111 on the balance shaft crossbeam 311 and connect to the air chamber tube bundle 21 of the middle axle 32, making the path setting of the tube bundle 21 more reasonable. Furthermore, since the overall size of the second fixing part 13 is larger than that of the first fixing part 12, the stress on the second fixing part 13 may be more complex during use. By setting the second sub-connecting section 1122 on the side of the first sub-connecting section 1121 adjacent to the first fixing part 12, the stress on the tube bundle support 100 is more balanced, avoiding the overall structural displacement or deformation of the tube bundle support 100 due to the large size of the second fixing part 13 and uneven stress. This improves the working stability of the tube bundle support 100 during use and also helps to improve the structural compactness of the entire tube bundle support 100.

[0054] According to some embodiments of the present invention, a plurality of first fixing grooves 141 are formed on the first fixing part 12. In the description of the present invention, "a plurality of" means two or more. The plurality of first fixing grooves 141 are respectively formed on both sides of the first fixing part 12 in the length direction of the connecting part 11, and the plurality of first fixing grooves 141 located on the same side are spaced apart along the width direction of the connecting part 11; and / or a plurality of second fixing grooves 142 are formed on the second fixing part 13, and the plurality of second fixing grooves 142 are respectively formed on both sides of the second fixing part 13 in the length direction of the connecting part 11, and the plurality of second fixing grooves 142 located on the same side are spaced apart along the width direction of the connecting part 11.

[0055] like Figure 1 As shown, the first fixing part 12 has two first fixing grooves 141 on each side of the length direction of the connecting part 11, and the second fixing part 13 has four second fixing grooves 142 on each side of the length direction of the connecting part 11. This arrangement increases the number of fixing grooves 14 on the tube bundle 21 on the tube bundle support 100. The design of multiple fixing grooves 14 allows the load borne by the tube bundle support 100 to be distributed to multiple fixing points, reducing the probability of damage to the tube bundle 21 due to local stress concentration, extending the service life of the tube bundle 21, and improving the reliability of the tube bundle support 100.

[0056] Furthermore, the multiple second fixing grooves 142 on the second fixing part 13 can constrain the tube bundle 21 from different directions, restricting the displacement of the tube bundle 21 in various directions. This effectively prevents the tube bundle 21 from shaking or shifting due to external forces such as vibration and impact during the driving of the vehicle 300, improves the fixing stability of the tube bundle 21, reduces the risk of interference and wear between the tube bundle 21 and the through hole 3111 of the balance shaft beam 311, and ensures braking safety.

[0057] It should be noted that the tube bundle support 100 is made of Q355 (low alloy high strength structural steel) with an overall thickness of 3mm, which makes the tube bundle support 100 lighter, reduces development costs, and is easy to install.

[0058] like Figure 3 As shown, the tube bundle positioning device 200 according to the second aspect embodiment of the present invention includes: a tube bundle support 100, a tube bundle 21 and fasteners (not shown).

[0059] The tube bundle support 100 is the tube bundle support 100 according to the first aspect embodiment of the present invention. The tube bundle 21 is located on one side of the tube bundle support 100 in the thickness direction. Fasteners are fitted into the fixing groove 14 of the tube bundle support 100 to fix the tube bundle 21 on the tube bundle support 100.

[0060] The tube bundle bracket 100 provides a stable support structure for the tube bundle 21, preventing it from swaying during vehicle 300 operation due to lack of fixation. This reduces the likelihood of contact and interference wear between the tube bundle 21 and the through hole 3111 of the balance shaft beam 311, ensuring the safety of the vehicle 300's braking system. Furthermore, the design of the tube bundle bracket 100 guides the installation of the tube bundle 21. Workers can quickly determine the installation position and method of the tube bundle 21 based on the location and distribution of the fixing slots 14. During installation, workers can place the tube bundle 21 on one side of the bracket's thickness direction and, by selecting a suitable fixing slot 14, fit the fasteners to it, improving the installation efficiency of the tube bundle 21. In addition, using fasteners in conjunction with the fixing slots 14 improves the convenience of fixing the tube bundle 21, further increasing installation efficiency. Moreover, the tube bundle positioning device 200 has high versatility, reducing design costs caused by differences in tube bundle 21 specifications and meeting the needs of different vehicle 300 usage scenarios. In addition, if a component of the tube bundle 21 or the tube bundle support 100 is damaged and needs to be replaced, the structural design of the tube bundle positioning device 200 makes the maintenance process more convenient. For the damaged tube bundle 21, it can be replaced simply by loosening the fasteners; for the damaged parts on the tube bundle support 100, the tube bundle support 100 can be repaired separately, reducing the cost and time of maintenance.

[0061] According to the embodiment of the present utility model, the tube bundle positioning device 200, by adopting the above-mentioned tube bundle bracket 100, reduces the probability of contact and interference wear between the tube bundle 21 and the through hole 3111 of the balance shaft beam 311, ensuring the safety of the braking system of the vehicle 300, improving the installation efficiency of the tube bundle 21, and the tube bundle positioning device 200 has high versatility and requires less maintenance cost and time.

[0062] like Figure 3 and Figure 4 As shown, the vehicle 300 according to the third aspect embodiment of the present invention includes the tube bundle positioning device 200 according to the second aspect embodiment of the present invention described above.
