Description

Technical Field

[0001] This utility model relates to the field of automotive structural technology, specifically to an integrated bracket for a side-mounted spare tire and an air tank, and the vehicle thereof. Background Technology

[0002] In the commercial vehicle sector, air tanks, as gas storage devices in automotive braking systems, are generally... Figure 1 The bracket shown is fixed to the vehicle frame. The spare tire plays a crucial role in ensuring driving safety for commercial vehicles, making the design and installation of its bracket essential. However, existing technologies have several problems:

[0003] 1) For tractor-trailers, the dual front axles and dual fuel tanks limit the space available for spare tire installation, resulting in almost no suitable spare tire brackets. Spare tires are typically installed at the factory in locations such as the saddle, and their removal can affect the normal use of the vehicle. Customers usually remove the spare tire themselves after purchasing the vehicle. Furthermore, factory-installed spare tires are often secured with wire straps, making installation and removal complex and difficult.

[0004] 2) Although some tractor units have space to accommodate and are designed with spare tire brackets, the spare tire brackets and air tank brackets are designed and installed separately, resulting in a large space occupation and a large overall weight.

[0005] 3) The spare tire bracket of the tractor unit is installed closer to the engine, which is a medium-strong excitation area. The requirements for the strength and rigidity of the bracket are higher. Directly using the spare tire mounting bracket of the cargo truck and dump truck will make it easier for the structure to be damaged. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an integrated bracket for a side-mounted spare tire and an air tank, and the vehicle thereof.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A side-mounted spare tire and air cylinder integrated bracket includes a pair of bracket bodies and a spare tire bracket, wherein the bracket bodies are fixedly connected to the same side of the vehicle frame; the spare tire bracket is connected to the bottom side of the two bracket bodies for mounting the spare tire; it also includes: a reinforcing beam, which is fixedly disposed on the outside of at least one of the bracket bodies; and an air cylinder bracket, which is mounted on the reinforcing beam for supporting the air cylinder; the installation height of the air cylinder bracket is higher than the installation height of the spare tire bracket, and the projections of the air cylinder and the spare tire on the horizontal plane partially overlap.

[0009] As a preferred technical solution, the side of the bracket body that connects to the vehicle frame is provided with an inner reinforcing plate, and the inner reinforcing plate and the bracket body together form a thickened connection area.

[0010] As a preferred technical solution, the bracket body and the inner reinforcing plate are provided with at least two bolt holes, which can be detachably connected to the vehicle frame by bolts.

[0011] As a preferred technical solution, the non-critical load-bearing area of ​​the support body is provided with weight-reducing holes; and / or, the height of the support body in the Z direction is configured as an extension structure, the extension amount being determined based on the spare tire size and ground clearance.

[0012] As a preferred technical solution, a transverse support frame is also included, which is connected between the two support bodies.

[0013] As a preferred technical solution, the transverse support frame is a groove structure with an open top, and tool operation notches are provided at the center of both side walls of the groove.

[0014] As a preferred technical solution, the cross-section of the gas storage cylinder support is Z-shaped, including a horizontal connecting surface at the bottom and an arc-shaped mounting surface at the top; the horizontal connecting surface is fixed to the groove of the reinforcing beam by a threaded connector, and the arc-shaped mounting surface is adapted to the outer diameter of the gas storage cylinder.

[0015] As a preferred technical solution, it also includes a spare tire mounting rod located at the bottom of the spare tire bracket, the top of which is detachably connected to the bottom of the spare tire bracket. The top of the spare tire mounting rod is provided with a positioning bolt and a positioning post for auxiliary positioning and installation of the spare tire.

[0016] As a preferred technical solution, the highest point of the air storage tank does not exceed the upper wing surface of the vehicle frame.

[0017] This utility model also discloses a vehicle equipped with an integrated bracket for a side-mounted spare tire and an air tank as described in any of the above claims.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention integrates the spare tire bracket and air cylinder bracket into a single bracket body, and utilizes the connection between the bracket body and the vehicle frame to achieve a more compact spatial layout for the spare tire and air cylinder on the side of the vehicle. The spare tire is mounted vertically upwards at the bottom of the spare tire bracket with the wheel axle centerline pointing upwards, while the air cylinder is placed on the arc-shaped mounting surface at the top of the air cylinder bracket. There is a partial overlap between the air cylinder and the spare tire in the horizontal projection. This staggered and partially overlapping layout makes full use of the vehicle's lateral three-dimensional space, greatly improving space utilization and providing more possibilities for the arrangement of other vehicle accessories or pipelines.

[0020] Unlike the traditional method of directly welding or fixing the air tank bracket to the vehicle frame, this design mounts the air tank bracket on the reinforcing beam on the outside of the bracket body, significantly increasing the disassembly and operation space and greatly facilitating the maintenance, repair, and replacement of the air tank and its bracket.

To simplify the disclosure of this utility model, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the utility model. Furthermore, reference numerals and / or reference letters may be repeated in different examples of this utility model; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or settings discussed. Therefore, in order to make the technical means, inventive features, and achieved objectives and effects of this utility model readily understandable, the utility model is further described below in conjunction with specific embodiments.

[0031] Please see Figures 2-4 This embodiment provides an integrated bracket for a side-mounted spare tire and an air cylinder, designed to optimize the side space layout of a vehicle and improve installation and maintenance convenience as well as structural strength. The integrated bracket mainly includes a bracket body 1, a spare tire bracket 2, and an air cylinder bracket 3.

[0032] The bracket body 1 is fixedly connected to the same side of the frame 4 in pairs at preset intervals; the spare tire bracket 2 is fixedly installed on the bottom side of the two bracket bodies 1 by threaded connection; the spare tire 7 is installed at the bottom of the spare tire bracket 2 with the wheel axle centerline vertically upward, specifically, the side of the spare tire 7, i.e., the rim mounting surface, serves as the main load-bearing surface and is in close contact with the bottom surface of the spare tire bracket 2. On the outer side of one of the bracket bodies 1, i.e., the side away from the spare tire bracket, two reinforcing beams 5 are vertically welded, and the air cylinder bracket 3 is welded to the reinforcing beams 5; the front and rear ends of the air cylinder 6 are respectively supported and placed on the specially provided arc-shaped mounting surfaces 31 on the top of the two air cylinder brackets 3. The arc-shaped surface matches the curvature of the air cylinder 6. Compared with the prior art of directly welding or fixing the air cylinder bracket to the frame body, this design installs the air cylinder bracket 3 on the reinforcing beam 5 on the outer side of the bracket body 1, which significantly increases the disassembly and operation space and greatly facilitates the maintenance, repair, and replacement of the air cylinder 6 and its bracket.

[0033] This embodiment of external mounting effectively saves connection space on the four side walls of the frame, providing more possibilities for the layout of other accessories or pipelines.

[0034] In some embodiments, the arc-shaped mounting surface of the air tank bracket 3 is positioned at a height (Z-direction) higher than the mounting surface of the spare tire 7 on the spare tire bracket 2. Simultaneously, the highest point of the air tank 6 is designed not to exceed the upper wing surface of the vehicle frame 4. This high-position mounting helps protect the air tank from impacts by ground obstacles; the air tank not exceeding the upper wing surface of the vehicle frame ensures compliance with overall vehicle height regulations and does not affect the utilization of overhead space. Furthermore, in the projection onto the horizontal XY plane, the air tank 6 and the spare tire 7 have a partially overlapping area. This staggered and partially overlapping spatial layout fully utilizes the lateral three-dimensional space of the vehicle, resulting in an extremely compact overall structure and significantly improving space utilization. While ensuring functionality and strength requirements, it effectively reduces the overall volume and floor space of the bracket system, saving material costs.

[0035] In some embodiments, to ensure that the connection strength meets the vehicle's driving load requirements, an inner reinforcing plate 11 is specially provided on the inner side of each bracket body 1 that contacts the vehicle frame 4. The reinforcing plate 11 and the bracket body 1 together constitute a thickened connection area, and the specific thickness data can be designed and determined according to the vehicle model and load requirements.

[0036] In some embodiments, three bolt holes 12 are provided on each bracket body 1 and its corresponding inner reinforcing plate 11. These bolt holes 12 correspond precisely to the reserved holes on the side of the frame 4, and a reliable connection is achieved by high-strength bolts. This design significantly enhances the connection rigidity and load-bearing capacity between the bracket body and the frame. At the same time, the multiple bolt connections provide a solid support and greatly facilitate the installation and disassembly of the bracket as a whole.

[0037] In some embodiments, multiple weight-reducing holes 13 are provided in the non-critical load-bearing areas of the support body 1, which effectively reduces the self-weight of the support body and achieves lightweighting; more importantly, it optimizes the load transmission path, promotes the more uniform distribution of stress to the critical bolt connections, significantly reduces local stress concentration, and improves the fatigue life and reliability of the support.

[0038] In some embodiments, in order to reduce the installation height of the spare tire 7 and improve vehicle passability and center of gravity stability, the bracket body 1 in this embodiment is specifically extended in the height direction Z direction compared with existing similar brackets. The extension amount needs to be determined according to the target spare tire size and the desired ground clearance.

[0039] In some embodiments, a transverse support frame 8 is typically provided between the two support bodies 1. This primarily serves to enhance the overall rigidity between the two support bodies 1, preventing relative displacement or deformation under stress, and further improving the overall stability and load-bearing capacity of the integrated support system. Furthermore, the transverse support frame 8 is a groove structure with an open top, and notches are provided at the center of both side walls of the groove to facilitate the loading and unloading of the spare tire using tools.

[0040] In some embodiments, the reinforcing beam may preferably be a channel steel structure; the cross-sectional shape of the gas storage cylinder support 3 may be designed to be approximately “Z” shaped, with a horizontal connecting surface 32 at its bottom, which is fixed inside the channel of the reinforcing beam 5 by threaded connectors; and an arc-shaped mounting surface 31 that is adapted to the outer diameter of the gas storage cylinder 6.

[0041] In some embodiments, the present invention further includes a spare tire hanging rod 9 disposed at the bottom of the spare tire bracket, the top of which is detachably connected to the bottom of the spare tire bracket 2. The top of the spare tire hanging rod 9 is provided with a positioning bolt and a positioning post for auxiliary positioning and installation of the spare tire.

[0042] To clearly describe the spatial relationships, the direction of the connection surface between the frame 4 and the bracket body 1 is defined as the X-direction; the direction of the main body of the bracket body 1, which extends outward perpendicularly to the side of the frame 4, is defined as the Y-direction; and the vertical height direction is defined as the Z-direction. The reinforcing beam 5 and the air tank bracket 3 are positioned along the X-direction. The axial direction of the air tank 6 is along the Y-direction; the axial direction of the spare tire 7 is along the wheel axle direction. In the Z-direction, the air tank 6 is installed higher than the spare tire 7.

[0043] This utility model also protects a vehicle equipped with the aforementioned side-mounted spare tire and air tank integrated bracket.

[0044] To ensure that the strength and stiffness of the side-mounted spare tire and air tank integrated bracket of this utility model meet the design requirements, a finite element model was built to conduct modal and impact condition simulation analysis. According to the analysis results, the structural design meets the usage requirements.

[0045] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
