The chassis of a heavy-duty truck is equipped with air chambers and brake valve assemblies, with brake hoses connecting the air chambers and brake valve assemblies to ensure the normal operation of the braking system.

[0003] In related technologies, the structural design of the fixed bracket is not reasonable enough, which leads to dynamic interference between the tube bundle and the air chamber and surrounding structural components, resulting in tube bundle wear. This not only increases the cost of the tube bundle but also seriously affects braking safety. In particular, with the increasing versatility and widespread use of dual rear axles in heavy-duty truck models, it is especially important to develop fixed brackets suitable for dual rear axle vehicles to ensure the safe arrangement of the air chamber tube bundle in dual rear axles.

[0030] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0031] The following is for reference. Figures 1-4 The present invention describes a fixing bracket 10 for a tube bundle 50 according to an embodiment of the present invention. The fixing bracket 10 for the tube bundle 50 can be applied to a vehicle 100, including but not limited to heavy trucks.

[0032] Combination Figures 1-4As shown, the fixing bracket 10 of the tube bundle 50 according to this utility model mainly includes: a connector 11 and a fixing member 12. The connector 11 has a connecting portion 111, which is adapted to be fixedly connected to the rear axle 20. The fixing member 12 is disposed at the end of the connector 11 and extends upward. The fixing member 12 is at least partially bent to form a clearance portion 121, which is adapted to clearance from the rear axle 20. The fixing member 12 has a binding portion 122, which is adapted to fix the tube bundle 50.

[0033] Specifically, the vehicle 100 is equipped with a rear axle 20 and an air chamber 30, with each rear axle 20 corresponding to at least one air chamber 30. The main function of the air chamber 30 is to convert the pressure of compressed air into mechanical force, thereby enabling the braking function of the vehicle 100. A hose bundle 50 is connected between the air chamber 30 and the brake valve assembly 40. When the driver presses the brake pedal, the brake valve assembly 40 will quickly operate, and compressed air can be directly transmitted to the air chamber 30 through the hose bundle 50, thereby braking the vehicle 100.

[0034] Understandably, in order to ensure the neat arrangement of the tube bundle 50 within the vehicle 100, avoid the tube bundle 50 from crossing or becoming cluttered, and avoid dynamic interference between the tube bundle 50 and the air chamber 30, it is necessary to fix and guide the tube bundle 50.

[0035] By providing a fixed bracket 10, which includes a connector 11 and a fixing member 12 connected to each other, and by placing the fixing member 12 at the end of the connector 11 and extending it upwards, and by bending the fixing member 12 at least partially to form a clearance portion 121, the connector 11 can be used to connect to the rear axle 20, and the clearance portion 121 can fully avoid the rear axle 20, preventing interference between the fixing member 12 and the rear axle 20 when the connector 11 is connected to the rear axle 20. This facilitates the connection between the fixed bracket 10 and the rear axle 20 and enables the fixed bracket 10 to be stably installed on the vehicle 100. Furthermore, the fixing member 12 can be used to fix the tube bundle 50, thereby fixing and guiding the tube bundle 50.

[0036] Specifically, by providing a connecting part 111 on the connector 11, it is possible to connect with the axle housing of the rear axle 20 through the connecting part 111, which makes the fixing of the connector 11 and even the fixing bracket 10 simpler and more convenient.

[0037] Furthermore, by providing a binding part 122 on the fixing member 12, the tube bundle 50 can be connected and fixed to the fixing member 12 by binding, and the tube bundle 50 can be firmly held in a predetermined position to prevent displacement caused by vibration, fluid impact or external force. This achieves fixation and guidance of the tube bundle 50, thereby avoiding dynamic interference between the tube bundle 50 and the air chamber 30, avoiding wear of the tube bundle 50, extending the service life of the tube bundle 50, and ensuring the braking safety of the vehicle 100.

[0038] Furthermore, it can be understood that bundling the tube bundles 50 allows multiple tube bundles 50 to be arranged neatly, reducing intersections and clutter between tube bundles 50, making the wiring more organized, suitable for layout in confined spaces, and improving space utilization. The tube bundles 50 are more controllable and manageable, reducing maintenance difficulties caused by messy wiring. When it is necessary to replace, inspect, or disassemble the tube bundles 50, the neat tube bundles 50 are easier to handle, reducing disassembly time and improving maintenance efficiency.

[0039] Therefore, by including a connector 11 and a fixing member 12 connected to each other, the connector 11 is provided with a connecting portion 111, the fixing member 12 extends upward and is at least partially bent to form a clearance portion 121, and the fixing member 12 is provided with a binding portion 122, the fixing bracket 10 can be fixedly connected through the connecting portion 111, and the tube bundle 50 can be fixed and guided through the binding portion 122. This can avoid dynamic interference between the tube bundle 50 and the air chamber 30, avoid wear of the tube bundle 50, extend the service life of the tube bundle 50, and ensure the braking safety of the vehicle 100.

[0040] Combination Figures 2-4 As shown, the connector 11 may include: a first connecting segment 112 and a second connecting segment 113. The first connecting segment 112 extends in the front-back direction, and the second connecting segment 113 is connected to one end of the first connecting segment 112 and bent relative to the first connecting segment 112. Both the first connecting segment 112 and the second connecting segment 113 are provided with a connecting part 111.

[0041] With this configuration, when connecting the fixed bracket 10 to the rear axle 20, the connector 11 can be adapted to the shape of the rear axle 20, so that the first connecting section 112 and the second connecting section 113 correspond to at least a portion of the rear axle 20, and then connected to the rear axle 20 through the connecting portion 111 on the first connecting section 112 and the connecting portion 111 on the second connecting section 113, respectively. This allows for connection between the connector 11 and the rear axle 20 in at least two directions. This results in a more uniform and reasonable distribution of the connection force between the connector 11 and the rear axle 20, improving the reliability of the connection between the connector 11 and even the fixed bracket 10 and the rear axle 20.

[0042] Furthermore, combined Figures 2-4 As shown, the connecting part 111 is an oblong mounting hole.

[0043] Specifically, the connecting part 111 can be configured as an oblong mounting hole, and correspondingly, a mounting hole can be configured on the rear axle 20 so that the oblong mounting hole corresponds to the mounting hole. Then, the fastener can pass through both the oblong mounting hole and the mounting hole and perform a fastening action, thereby realizing the connection between the connecting part 11 and even the fixed bracket 10 and the rear axle 20.

[0044] Furthermore, by installing elongated holes, the hole position deviation caused by manufacturing errors of the fixed bracket 10 and the rear axle 20 can be positioned more flexibly, thereby facilitating the connection between the connector 11 and the rear axle 20 and reducing the risk of rework or scrap due to hole position deviation.

[0045] Combination Figures 2-4 As shown, the fastener 12 may include a first fastening segment 123, a second fastening segment 124 and a third fastening segment 125 connected in sequence.

[0046] Specifically, one end of the first fixing segment 123 is connected to the end of the second connecting segment 113 away from the first connecting segment 112, and the other end of the first fixing segment 123 extends upward toward the side away from the second connecting segment 113. One end of the second fixing segment 124 is connected to the other end of the first fixing segment 123. The second fixing segment 124 is bent relative to the first fixing segment 123 and is inclined upward in the front-back direction toward the same side as the first connecting segment 112. The third fixing segment 125 is connected to the second fixing segment 124 and is bent relative to the second fixing segment 124. The third fixing segment 125 is inclined downward in the front-back direction toward the same side as the first connecting segment 112.

[0047] In this way, the fixing member 12 can be adapted to the shape of the axle housing of the rear axle 20. Not only can the rear axle 20 be fully avoided by the avoidance part 121, preventing interference between the fixing bracket 10 and the rear axle 20 when they are connected, thus facilitating the connection between the fixing bracket 10 and the rear axle 20, but the tube bundle 50 can also be guided along the extension direction of the fixing member 12, making the arrangement of the tube bundle 50 more regular, avoiding dynamic interference between the tube bundle 50 and the air chamber 30 and other components of the vehicle 100, ensuring the structural reliability of the tube bundle 50, and ensuring the braking safety of the vehicle 100.

[0048] Furthermore, both the second fixing section 124 and the third fixing section 125 are provided with binding parts 122, so that the tube bundle 50 can be selectively bound to at least one of the second fixing section 124 and the third fixing section 125 according to the actual arrangement and needs of the tube bundle 50, thereby ensuring stable fixation and precise guidance of the tube bundle 50.

[0049] One or more binding parts 122 can be provided along the length of the second fixing section 124 and the third fixing section 125, respectively, to fix the tube bundle 50 and avoid disorder caused by the unfixed part of the tube bundle 50 being too long, as well as dynamic interference with the air chamber 30.

[0050] Combination Figure 2 and Figure 3 As shown, the binding part 122 is a cable tie slot. Specifically, the binding part 122 can be set as a cable tie slot, and correspondingly, each cable tie slot is provided with at least one cable tie 60 to cooperate with it. In this way, the cable tie 60 can be used to bind and fix the tube bundle 50, and the cable tie slot can also accommodate the cable tie slot, restricting the displacement of the cable tie 60 and ensuring the stable setting of the cable tie 60. This facilitates the fixing and guiding of the tube bundle 50, and ensures the stability and reliability of the fixing bracket 10 in fixing and guiding the tube bundle 50.

[0051] Combination Figure 3 and Figure 4 As shown, a bent portion 126 is provided at the end of the third fixed section 125, and the bent portion 126 is bent downward relative to the third fixed section 125. Specifically, after the tube bundle 50 is bundled and fixed to the fastener 12, the tube bundle 50 continues to extend along the length direction of the third fixed section 125. By providing a bent portion 126 at the end of the third fixed section 125 and bending the bent portion 126 downward relative to the third fixed section 125, the bent portion 126 can avoid the tube bundle 50, preventing dynamic interference between the end of the third fixed section 125 and the tube bundle 50, avoiding wear on the tube bundle 50, and extending the service life of the tube bundle 50.

[0052] In some embodiments of this utility model, the fixing bracket 10 of the tube bundle 50 is an integrally formed structural component. This not only simplifies the manufacturing process of the fixing bracket 10, facilitates the production and manufacturing of the fixing bracket 10, and improves the production efficiency of the fixing bracket 10, but also ensures the structural strength of the fixing bracket 10, ensures the connection strength between the fixing component 12 and the connecting component 11, and improves the structural reliability of the fixing bracket 10.

[0053] Furthermore, the fixing bracket 10 of the tube bundle 50 is made of Q355 steel. Specifically, the fixing bracket 10 can be made of Q355 steel, which has higher strength, stronger load-bearing capacity, and better impact resistance, thereby improving the structural reliability and stability of the fixing bracket 10 of the tube bundle 50. A 3mm thick material can be used, making the fixing bracket 10 lighter, reducing development costs, and facilitating installation.

[0054] Combination Figure 1 and Figure 2As shown, the vehicle 100 according to this utility model may mainly include: the fixing bracket 10 of the tube bundle 50 mentioned above.

[0055] Specifically, by applying the fixing bracket 10 of the tube bundle 50 to the vehicle 100, the tube bundle 50 between the air chamber 30 and the brake valve assembly 40 can be fixed and guided, optimizing the arrangement of the tube bundle 50 and avoiding dynamic interference between the tube bundle 50 and the air chamber 30. This not only makes the management of the tube bundle 50 simpler and more convenient, reducing the management cost of the tube bundle 50, but also ensures braking safety, thereby improving the performance of the vehicle 100 and enhancing the product competitiveness of the vehicle 100.

[0056] Furthermore, combined Figure 1 As shown, there is at least one rear axle 20 and at least one fixing bracket 10 for the tube bundle 50, with each fixing bracket 10 corresponding to at least one rear axle 20. In this way, the fixing bracket 10 for the tube bundle 50 can be adapted to the design of one or more rear axles 20, optimizing the arrangement of the tube bundle 50, reducing the management cost of the tube bundle 50 of the vehicle 100, and improving the braking safety of the vehicle 100.

[0057] In one specific embodiment of this utility model, combined with Figure 1 and Figure 2 The vehicle 100 is provided with two rear axles 20, which are spaced apart in the front-rear direction, and each rear axle 20 corresponds to two air chambers 30.

[0058] Two fixing brackets 10 for tube bundle 50 can also be set. The two fixing brackets 10 for tube bundle 50 are respectively set on the two rear axles 20. Each fixing bracket 10 for tube bundle 50 fixes and guides the tube bundle 50 connected to the two air chambers 30 corresponding to each rear axle 20. This enables the application of fixing brackets 10 for tube bundle 50 in dual rear axle vehicles, making the arrangement of tube bundle 50 in dual rear axle vehicles more orderly and safe.

[0059] Furthermore, the two air chambers 30 corresponding to each rear axle 20 are arranged symmetrically, and the fixed bracket 10 is set on the rear axle 20 and located on the axis of symmetry of the two air chambers 30. This makes the distance from the tube bundle 50 connected to each air chamber 30 to the fixed bracket 10 equal, and makes the arrangement of the tube bundle 50 more neat and orderly.

[0060] Preferably, the two fixed supports 10 are arranged symmetrically at the center, so that the force on the vehicle 100 as a whole is more even and reasonable, reducing stress concentration and deformation, thereby improving the reliability of the vehicle 100.
