Description

Technical Field

[0001] This utility model belongs to the field of truck technology, and in particular relates to a vehicle bracket assembly integrating a spare tire and an air tank, as well as a vehicle. Background Technology

[0002] To achieve energy conservation and emission reduction, the commercial vehicle sector is placing increasingly stringent demands on lightweight chassis, optimized space layout, and cost control. Spare tires and air tanks, as standard equipment in commercial vehicles, are traditionally installed as separate, independent units. Specifically, for example... Figure 1 As shown, existing technologies generally employ the following approach: on one side of the vehicle frame, the spare tire bracket assembly is fixed to the frame using bolts and nuts to support the wheel and tire assembly; while on the other side of the frame, a separate air cylinder bracket, air cylinder fixing straps, and matching fasteners are required to separately install the air cylinder assembly onto the frame. This layout, with the spare tire and air cylinder located on opposite sides of the vehicle frame, is the closest existing technology in the field.

[0003] However, the existing split-type layout has several inherent drawbacks. First, it increases the number of components, requiring more metal to construct the two independent brackets and consuming more standard fasteners, directly increasing the overall vehicle weight and production costs—contrary to the design principles of lightweighting and cost reduction. Second, this design encroaches on valuable layout space on both sides of the chassis, making the placement of chassis pipelines, batteries, urea tanks, and other components cramped, limiting the compactness and versatility of the chassis design. Furthermore, two independent bracket systems mean that assembly work needs to be performed on both sides of the chassis separately, increasing assembly steps and time on the production line and reducing assembly efficiency. Simultaneously, two independent mounting points introduce more potential sources of vibration and noise, and impose dispersed requirements on the structural strength of different parts of the chassis. Therefore, developing an integrated bracket solution that can effectively address these problems has become an urgent technical issue to be solved in this field. Utility Model Content

[0004] In view of the problems caused by the separate and independent arrangement of the spare tire and air tank in the prior art, such as a large number of parts, heavy vehicle weight, limited layout space, low assembly efficiency and dispersed structure, this utility model provides a vehicle bracket assembly that integrates the spare tire and air tank, as well as a vehicle.

[0005] This utility model is implemented as follows: a vehicle bracket assembly integrating a spare tire and an air cylinder, characterized in that it includes a spare tire bracket assembly, an air cylinder mounting unit, and an intermediate connector: the spare tire bracket assembly is used to install the spare tire and can be fixed to the vehicle frame assembly by the connector; the air cylinder mounting unit is used to install the air cylinder; at least one intermediate connector is fixedly connected between the spare tire bracket assembly and the air cylinder mounting unit, for integrating the air cylinder mounting unit onto the spare tire bracket assembly.

[0006] In the above technical solution, preferably, the air tank installation unit includes an air tank bracket, and the air tank bracket is fixed to the spare tire bracket assembly through the intermediate connector.

[0007] In the above technical solution, preferably, the intermediate connecting member includes a first intermediate bracket and a second intermediate bracket, both of which are fixedly connected to the spare tire bracket assembly, and the air tank bracket is simultaneously fixed to the first intermediate bracket and the second intermediate bracket.

[0008] In the above technical solution, preferably, the first intermediate bracket and the second intermediate bracket are fixed to the spare tire bracket assembly by welding.

[0009] In the above technical solution, preferably, the gas storage cylinder support is fixed to the first intermediate support and the second intermediate support by bolt and nut assembly.

[0010] In the above technical solution, preferably, the spare tire bracket assembly is fixed to the vehicle frame assembly by vehicle frame bolts and nuts.

[0011] In the above technical solution, preferably, the gas storage cylinder support is provided with a structure for fixing the gas storage cylinder fixing strap.

[0012] In the above technical solution, preferably, the spare tire bracket assembly, the intermediate connector and the air tank installation unit are made of lightweight materials.

[0013] In the above technical solution, preferably, the lightweight material is high-strength steel or aluminum alloy. This utility model achieves a series of synergistic and unexpected beneficial effects by highly integrating the spare tire bracket and the air tank bracket, compared to the traditional separate design.

[0014] First and foremost, the most direct effect is significant weight reduction and cost reduction. This integrated bracket eliminates the need for a separate air tank bracket and its complex installation structure on the other side of the frame, which not only reduces the amount of steel used but also significantly saves on standard fasteners such as bolts and nuts, achieving a reduction in the number of parts and realizing the goal of weight and cost reduction from the source.

[0015] Secondly, this utility model greatly optimizes the chassis space layout and versatility. It integrates the spare tire and air tank, which originally occupied both sides of the frame, into one side, freeing up valuable space for the placement of other chassis components such as the battery and urea tank, improving the compactness and neatness of the chassis design. At the same time, as a complete module, this integrated component is easier to achieve universality on different vehicle platforms, improving R&D efficiency and parts reuse rate.

[0016] This integrated structure also implicitly enhances the overall structural performance. The spare tire bracket, intermediate connector, and air tank bracket together form a high-rigidity frame structure, which not only optimizes load distribution and reduces stress concentration at the main connection points of the frame, improving long-term reliability, but also effectively suppresses vibration, thus playing a positive role in improving the overall vehicle performance.

[0017] The second objective of this invention is to provide a vehicle comprising a frame assembly and a vehicle support assembly integrating a spare tire and an air reservoir as described in any of the preceding descriptions. Attached Figure Description

[0018] Figure 1 This is a structural diagram of existing technology; Figure 2 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0020] To overcome the shortcomings of existing technologies, this utility model provides a vehicle bracket assembly integrating a spare tire and an air tank, as well as a vehicle. To further illustrate the structure of this utility model, a detailed description is provided below in conjunction with the accompanying drawings: Reference Figure 2 This utility model provides a vehicle bracket assembly that integrates a spare tire and an air tank, including a spare tire bracket assembly 3, an intermediate connector and an air tank mounting unit.

[0021] The spare tire bracket assembly 3 is made of high-strength steel by stamping, and its structure is similar to that of conventional spare tire brackets in the field. It is mainly used to support and fix the wheel assembly 10. The spare tire bracket assembly 3 has an integrated interface area pre-designed on it for welding intermediate connecting parts. The spare tire bracket assembly 3 is fixedly installed on the left or right side of the frame assembly 1 by frame bolts and nuts 2. The specific installation position can be determined according to the overall chassis layout of the vehicle.

[0022] In this embodiment, the intermediate connector comprises two independent components: a first intermediate bracket 5 and a second intermediate bracket 7. Both the first intermediate bracket 5 and the second intermediate bracket 7 are made of high-strength steel and are securely and non-removably connected to the pre-designed integrated interface area of ​​the spare tire bracket assembly 3 by welding. The first intermediate bracket 5 and the second intermediate bracket 7 are symmetrically distributed in space. This symmetrical layout is not only for stability. When the vehicle vibrates, the vibration load generated by the air tank 4 is evenly transmitted to the two intermediate brackets through the air tank bracket 8, and further distributed to multiple areas where the spare tire bracket assembly 3 connects to the vehicle frame. This design avoids stress concentration, and in particular significantly reduces the additional bending moment and torsional load borne by the main bolts (vehicle frame bolts and nuts 2) connecting the spare tire bracket assembly 3 to the vehicle frame, thereby implicitly improving the long-term reliability and fatigue life of the main connection point between the entire bracket assembly and the vehicle frame.

[0023] In this embodiment, the gas cylinder mounting unit is specifically a U-shaped gas cylinder bracket 8. Both ends of the gas cylinder bracket 8 are fixedly connected to the first intermediate bracket 5 and the second intermediate bracket 7 via intermediate bracket fixing bolts and nuts 6. Thus, the gas cylinder bracket 8 is suspended and securely integrated into the spare tire bracket assembly 3.

[0024] During assembly, first, the air tank 4 is tied to the air tank bracket 8 with the air tank fixing strap 9. Then, the spare tire bracket assembly 3 is installed onto the frame assembly 1 as a whole through the frame bolts and nuts 2. Finally, the wheel assembly 10 (i.e. the spare tire) is installed onto the spare tire bracket assembly 3.

[0025] The first intermediate bracket 5 and the second intermediate bracket 7 are pre-welded to the spare tire bracket assembly 3 and connected to the air tank bracket 8 using detachable bolts and nuts 6. This "welded and bolted" design optimizes the assembly process. On the final assembly line, workers can easily install the air tank 4 and air tank fixing strap 9 onto the air tank bracket 8 at the sub-assembly station, forming an "air tank sub-assembly." Subsequently, by tightening only a few sets of bolts and nuts 6, this sub-assembly can be quickly and accurately installed onto the spare tire bracket assembly 3, which already has the intermediate brackets welded to it. This "sub-assembly-final assembly" mode solves the problems of difficult handling of the original integrated large assembly and limited operating space under the vehicle, greatly improving the efficiency and convenience of chassis line assembly and reducing the assembly error rate. This is a technological advantage that the split structure does not possess.

[0026] The spare tire bracket assembly 3, intermediate brackets 5 and 7, and air tank bracket 8 together form a semi-enclosed, approximately triangular frame structure. This integrated frame structure itself has high bending and torsional stiffness. Due to the increased stiffness of the entire component, the vibration amplitude and noise generated by engine or road excitation during vehicle operation will be reduced accordingly, which has a potentially positive impact on improving the overall driving experience of the vehicle.

[0027] Example 2 The difference between this embodiment and Embodiment 1 is that the intermediate connector is a single, integrally formed sheet metal part or casting. This integral intermediate connector is fixed to the spare tire bracket assembly 3 by welding or bolting, and the air tank bracket 8 is then bolted or welded to this integral intermediate connector. This solution reduces the number of parts and simplifies the assembly process. This embodiment supports the overarching generalization of "at least one intermediate connector," indicating that the number and structural form of the intermediate connector can vary.

[0028] Example 3: The difference between this embodiment and Embodiment 1 is that the gas cylinder mounting unit is not a separate gas cylinder bracket 8, but rather consists of mounting arms or hooks extending directly from the intermediate connectors (first intermediate bracket 5 and second intermediate bracket 7). The gas cylinder 4 is directly secured to these mounting arms or hooks via the gas cylinder fixing strap 9. This embodiment supports the broader generalization of "gas cylinder mounting unit," indicating that it can be an independent bracket or an integrally formed mounting structure with other components.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
