In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0049] This embodiment provides a frame assembly. In particular, the frame assembly is applied to commercial vehicles. Figures 1 to 5 As shown, the vehicle frame assembly includes a vehicle frame 5, a rear axle 6 arranged on the vehicle frame 5, a rear axle 6 relay valve, a spring brake cylinder 8 and a dual-channel electronic pressure control module 9. In addition, the vehicle frame assembly also includes an integrated pipe bundle assembly.

[0050] Reference Figures 1 to 4 As shown, the integrated tube bundle assembly includes a tube bundle 1, a bracket 2, a clamp 3 and a buffer bushing 4, wherein the tube bundle 1 includes a main tube 11 and a branch tube 12, at least two branch tubes 12 are provided at both axially opposite ends of the main tube 11, the main tube 11 is connected to the branch tube 12, and a quick-connect connector 13 is provided at the end of the branch tube 12. The bracket 2 is used for fixed connection with the vehicle frame 5 and / or the rear axle 6. The clamp 3 is provided on the bracket 2. The buffer bushing 4 is sleeved on the tube bundle 1, and the clamp 3 clamps the tube bundle 1 through the buffer bushing 4, and the buffer bushing 4 is used to provide a flexible buffer between the clamp 3 and the clamped tube bundle 1.

[0051] Reference Figures 1 to 5 As shown, in this embodiment, the first end of the main pipe section 11 is provided with four branch pipe sections 12, and the second end of the main pipe section 11 is provided with two branch pipe sections 12, two of the branch pipe sections 12 at the first end of the main pipe section 11 are connected to the spring brake cylinder 8, the other two branch pipe sections 12 at the first end of the main pipe section 11 are connected to the dual-channel electronic pressure control module 9, and the two branch pipe sections 12 at the second end of the main pipe section 11 are connected to the relay valve of the rear axle 6.

[0052] In this embodiment, the tube bundle 1 of the integrated tube bundle assembly includes a main tube 11 and a branch tube 12. The branch tube 12 is arranged at two axially opposite ends of the main tube 11, and each end of the main tube 11 is provided with at least two branch tubes 12. With such an arrangement, the traditional multiple independent single tubes can be integrated into an integrated tube bundle 1. Through one tube bundle 1, multiple components can be connected, which effectively improves the integration, simplifies the structure, avoids the situation of redundant wiring harnesses, and correspondingly reduces the number of bolts and other connectors, which is convenient for relevant personnel to assemble, repair and replace. In addition, the buffer bushing 4 is sleeved on the tube bundle 1, and the buffer bushing 4 is clamped by the clamping member 3 to fix the tube bundle 1 on the bracket 2. The arrangement of the buffer bushing 4 can provide flexible buffering between the clamping member 3 and the clamped tube bundle 1, avoiding damage to the tube bundle 1 caused by the hard contact between the clamping member 3 and the outer surface of the tube bundle 1 after long-term use, and effectively ensures the service life of the integrated tube bundle assembly.

[0053] The vehicle frame assembly provided in this embodiment includes the above-mentioned integrated tube bundle assembly, which simplifies the number of parts and components, improves the overall integration, and achieves the lightweight of the entire frame 5, making it easier for relevant personnel to perform assembly, maintenance and replacement work.

[0054] As an optional implementation, the material of the buffer bushing 4 can be rubber.

[0055] Optionally, the specific structure of the clamping member 3 is prior art.

[0056] Specifically, the buffer bushing 4 has a penetration cavity 41, and the shape of the penetration cavity 41 is set to be petal-shaped. The petal-shaped penetration cavity 41 has multiple convex cavity parts 411, and the multiple convex cavity parts 411 are connected by the inner concave cavity parts 412, and each convex cavity part 411 is used to fit with a branch pipe part 12. Specifically, each convex cavity part 411 is used to clamp a branch pipe part 12. By setting the penetration cavity 41 to be petal-shaped, each "petal" of the penetration cavity 41, that is, each convex cavity part 411 can fit with a branch pipe part 12, thereby realizing the simultaneous fixation of multiple branch pipe parts 12 at the same end of the main pipe part 11.

[0057] Optionally, the number of the outer convex cavity portions 411 of the petal-shaped penetration cavity 41 is adaptively adjusted according to actual conditions.

[0058] Optionally, the shape of the penetration cavity 41 can be set to other structures besides the petal shape. As an optional embodiment, the penetration cavity 41 includes a plurality of independently arranged cavities, each of which is used to penetrate a corresponding branch pipe part 12, and each cavity is correspondingly fitted with a corresponding branch pipe part 12, so that multiple branch pipe parts 12 at the same end of the main pipe part 11 can be fixed at the same time.

[0059] Optionally, the buffer bushing 4 is provided with an opening 42 along the direction of the tube bundle 1. The opening 42 is provided to facilitate the installation of the buffer bushing 4 on the tube bundle 1. Specifically, in this embodiment, it is convenient to simultaneously install multiple branch pipes 12 at the same end of the main pipe part 11 in the installation cavity 41 and respectively fit with the corresponding outer convex cavity part 411.

[0060] Optionally, the shape of the buffer bushing 4 is set to be cylindrical. Specifically, during actual assembly, since the length of the tube bundle 1 is relatively long, the tube bundle 1 has natural bending, which generates a torsional force to drive the buffer bushing 4, so that the buffer bushing 4 cannot fit tightly against the clamping member 3, affecting the assembly efficiency and the clamping effect of the clamping member 3. Therefore, it is preferred to set the shape of the buffer bushing 4 to be cylindrical, which alleviates the influence of the torsional force of the tube bundle 1, improves the assembly efficiency without affecting the tightness of the assembly, and ensures the reliable clamping of the clamping member 3.

[0061] It is worth mentioning that the shape of the buffer bushing 4 can be set to other shapes besides cylindrical, such as Figure 2 The shapes in the figure are not limited too much here.

[0062] Specifically, a connection hole 201 is provided on the bracket 2, and the first bolt passes through the connection hole 201 and is fixedly connected to the frame 5 and / or the rear axle 6. Specifically, the bracket 2 has a first frame part 21, a second frame part 22, a third frame part 23 and a fourth frame part 24 connected in sequence. Among them, the first frame part 21 is arranged in parallel with the third frame part 23, the second frame part 22 is arranged in parallel with the fourth frame part 24, the first frame part 21 is perpendicular to the second frame part 22, and the connection hole 201 is provided on the first frame part 21 and / or the fourth frame part 24. Specifically, the first frame part 21 and the second frame part 22 are used to support and limit the clamping member 3 together, and the third frame part 23 and the fourth frame part 24 are used to support and limit the frame 5. In this embodiment, the connection hole 201 provided on the first frame part 21 can be used to connect with the frame 5, and can also be used to connect with the clamping member 3, and a bolt or other connecting member can be configured accordingly to achieve fixation with the clamping member 3.

[0063] Specifically, the first frame portion 21 , the second frame portion 22 , the third frame portion 23 and the fourth frame portion 24 are integrally formed.

[0064] In this embodiment, a card slot 202 is provided between the first frame portion 21 and the second frame portion 22, and a card connector (not shown) is correspondingly provided on the clamping member 3, and the card connector is engaged with the card slot 202. Such an arrangement can realize convenient and reliable fixing of the clamping member 3, and the structure is simple and easy to install.

[0065] In some other optional embodiments, a threaded hole is defined between the first frame portion 21 and the second frame portion 22, a through hole (not shown) is correspondingly defined on the clamping member 3, and the second bolt passes through the through hole and is threadedly connected to the threaded hole.

[0066] In this embodiment, two brackets 2 are provided. The brackets 2 include a first bracket 2A and a second bracket 2B. The first bracket 2A is fixedly connected to the vehicle frame 5, and the second bracket 2B is fixedly connected to the rear axle 6. In this way, the integrated tube bundle assembly, the vehicle frame 5, and the rear axle 6 can be fixed, further improving the reliable connection between the integrated tube bundle assembly and the vehicle frame assembly.

[0067] Optionally, the first bracket 2A and the second bracket 2B can be respectively arranged at one-third and two-thirds of the axial length of the tube bundle 1, so as to ensure that the tube bundle 1 has a small fluctuation in the interval without fixed points, and prevent the tube bundle 1 from collision, interference and damage. Compared with the solution with only one bracket 2, the tube bundle 1 has a small vibration fluctuation and is safer. Compared with the solution with three or more brackets 2, it is more cost-effective and ensures assembly efficiency.

[0068] In this embodiment, the length of the tube bundle 1 is designed to be about 25% longer than the straight-line distance connecting the components (the specific length is related to the vehicle load, the suspension system, and the position of the air inlet of the spring cylinder). This design can prevent the tube bundle 1 from being torn off and causing air leakage due to relative displacement of the components during the dynamic driving of the vehicle when the tube bundle 1 is designed to be too short. It can also prevent the tube bundle 1 from being damaged due to interference with the vehicle components caused by the tube bundle 1 being too long.

[0069] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
