Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The following is for reference. Figures 1-3 The integrated rear suspension assembly 100 according to a first aspect embodiment of the present invention is described.

[0023] Combination Figure 1 and Figure 2 An integrated rear suspension assembly 100 according to a first aspect embodiment of the present invention includes: a crossbeam body 10, a first bracket 22 for mounting an electronic control sensor module, a second bracket 24 for mounting a braking module, and a third bracket 26 for mounting a pipeline module. The crossbeam body 10 is a hollow tube, and a first connecting screw hole 11 and a second connecting screw hole 12 are provided in the middle section of the crossbeam body 10.

[0024] The main body of the crossbeam 10 is made of a hollow tube, which reduces the amount of material used, thereby reducing the overall weight and better meeting the requirements for lightweighting. By reducing the weight of the main body of the crossbeam 10, it also helps to reduce the energy consumption of the vehicle 1000 during operation, improve energy utilization efficiency, and to a certain extent extend the driving range, thereby enhancing the energy economy and environmental performance of the entire vehicle.

[0025] In some technical solutions, the main body 10 of the crossbeam is a casting. Compared to some welded crossbeams, the casting of this application reduces joints, thereby lowering stress concentration points, resulting in better fatigue resistance, extending the service life of the integrated rear suspension assembly 100, and reducing maintenance costs.

[0026] This application also provides the first connecting screw hole 11 and the second connecting screw hole 12 on the crossbeam body 10, so that some accessory devices can be installed on the crossbeam body 10 through brackets and other connecting parts, and the originally scattered and independent accessory devices can be integrated into a highly integrated rear suspension assembly 100 through unified planning and integration.

[0027] Furthermore, since the first connecting screw hole 11 and the second connecting screw hole 12 are integrated on the crossbeam body 10, no additional nuts are required during assembly, reducing the complexity of alignment and tightening. Fixing is achieved simply by screwing fasteners into the pre-set first connecting screw hole 11 or second connecting screw hole 12 through the mounting holes of the bracket, simplifying the assembly process and improving assembly efficiency. Simultaneously, it provides a certain compatibility basis for automated production lines, contributing to the realization of automated manufacturing.

[0028] In some specific designs, the main body 10 of the crossbeam is provided with reserved holes. By setting the internal thread structure in these reserved holes, it is possible to connect the external thread structure of the fastener, thereby eliminating the need for the independent nut required in the traditional connection method and enhancing the reliability and consistency of the connection.

[0029] Furthermore, the main body 10 of the crossbeam, the first connecting screw hole 11, and the second connecting screw hole 12 are integrally cast parts. This design makes the integrated rear suspension assembly 100 more robust and its structure simpler. Since no additional nuts are needed, assembly is easier and less prone to loosening.

[0030] In some optional embodiments, the first connecting screw hole 11 and the second connecting screw hole 12 can be spaced apart circumferentially along the crossbeam body 10, or spaced apart axially along the crossbeam body 10. Alternatively, depending on actual installation requirements, some screw holes can be arranged circumferentially and some axially, forming a mixed distribution. This allows the position of the connecting screw holes to be set according to the installation angle and position requirements of different brackets, enabling the brackets to be fixed to the crossbeam body 10 in a more reasonable way, which is beneficial for optimizing the space utilization of the vehicle 1000 and avoiding interference between components.

[0031] In addition to improving the flexibility of the connection structure, the structure of the bracket itself can also be very flexible.

[0032] Here, the structures of the first support 22, the second support 24, and the third support 26 can be completely identical, partially identical and partially different, or all of these supports can be completely different.

[0033] Specifically, the specific structure of each bracket can be designed independently according to the type and function of the component to be supported, and this application does not impose any specific restrictions.

[0034] For example, the first bracket 22 is mounted on the crossbeam body 10. The first bracket 22 is used to install the electronic control sensor module 200. The first bracket 22 has a first mounting hole 221, which corresponds to the first connecting screw hole 11, and the first mounting hole 221 and the first connecting screw hole 11 are connected by fasteners. The second bracket 24 is mounted on the crossbeam body 10, and the second bracket 24 is used to install the brake valve module 300. The second bracket 24 has a second mounting hole 2411, which corresponds to the second connecting screw hole 12, and is connected by fasteners. The third bracket 26 is mounted on the crossbeam body 10. The third bracket 26 is used to install the pipeline module 400. The third bracket 26 has a third mounting hole 2611, which corresponds to either the first connecting screw hole 11 or the second connecting screw hole 12, and is connected by fasteners.

[0035] All three types of brackets are modularly installed by engaging with pre-set connection screw holes on the main body 10 of the crossbeam. Each bracket can be individually designed according to the specific requirements of the components it supports, ensuring reliable connections while improving assembly efficiency and ease of maintenance.

[0036] In this application, the number of the first connecting screw holes 11 and the second connecting screw holes 12 can correspond one-to-one with the number of the first mounting holes 221, the second mounting holes 2411 and the third mounting holes 2611 that need to be connected. However, this application is not limited to this, and more connecting screw holes can be provided to facilitate the expansion or adjustment of functional modules according to actual needs in the later stage, thereby improving the adaptability and flexibility of the overall structure.

[0037] It is worth noting that the fasteners mentioned in this application can be bolts, screws, or other fasteners suitable for threaded connections, such as studs, self-tapping screws, etc. The specific type can be selected according to the actual assembly requirements. This application does not impose specific restrictions, and will not elaborate further below.

[0038] In summary, the integrated rear suspension assembly 100 of this application embodiment is directly mounted on the crossbeam body 10 with connecting screw holes through multiple brackets, realizing the integration and consolidation of multiple components, improving the structural compactness of the rear suspension assembly, simplifying the assembly process, improving connection reliability, and also providing certain support for the lightweighting of the whole vehicle.

[0039] According to some optional embodiments of the integrated rear suspension assembly 100, the first connecting screw hole 11 and the second connecting screw hole 12 are located on opposite sides of the crossbeam body 10. In the above technical solution, the first connecting screw hole 11 and the second connecting screw hole 12 are staggered, so that different brackets can be spatially offset from each other during installation, avoiding mutual interference and ensuring the rationality of assembly. At the same time, it also facilitates the independent connection of different functional modules.

[0040] For example, the first connecting screw hole 11 and the second connecting screw hole 12 can be arranged opposite each other along the front-rear direction of the vehicle 1000. When the first bracket 22 is used to connect the electronic control sensor module 200, it can be installed in the position of the crossbeam body 10 facing the front of the vehicle 1000, which facilitates the arrangement of the electronic control sensor module 200; when the second bracket 24 is used to connect the brake valve module 300, it can be installed in the position of the crossbeam body 10 facing the rear of the vehicle 1000, which facilitates the installation and arrangement of the brake valve module 300.

[0041] All the first connecting screw holes 11 and all the second connecting screw holes 12 are arranged at intervals along the length of the main body of the crossbeam 10.

[0042] In this way, multiple connection points can be distributed along the length of the main beam 10, thereby distributing the force and improving the stability of the structure. In some specific embodiments, the first bracket 22 is connected to the main beam 10 through two first connecting screw holes 11, and the second bracket 24 is fixed through two second connecting screw holes 12. This arrangement helps to distribute the force borne by the brackets more evenly to the main beam 10 through multiple connection points, avoiding local stress concentration and improving the strength of the structure.

[0043] Furthermore, by providing first connecting screw holes 11 and second connecting screw holes 12 distributed along the length direction on the crossbeam body 10, the same crossbeam can be adapted to multiple functional modules in vehicles with different wheelbases. Specifically, by simply selecting the appropriate screw holes according to the vehicle model to install the corresponding functional module, the installation requirements of different functional modules can be met, without the need to design a separate crossbeam structure for each vehicle model, thereby reducing development costs and production complexity.

[0044] Further optionally, the distance between all the first connecting screw holes 11 and the distance between all the second connecting screw holes 12 can be set to uniform or non-uniform distribution according to actual needs.

[0045] A uniform distribution facilitates the standardization of installation space and enables modular design; while a non-uniform distribution allows for flexible adjustments based on the shape and size of different functional modules to meet actual assembly requirements. This design also makes it easier to adapt to functional modules of different vehicle models.

[0046] In some alternative embodiments, the first bracket 22 and the second bracket 24 are arranged opposite each other along the longitudinal direction of the vehicle 1000. The third bracket 26 is located below the crossbeam body 10.

[0047] In the above technical solution, the first bracket 22 is arranged in front of the main body of the crossbeam 10 and the second bracket 24 is arranged behind it. This helps to arrange the functional modules that are connected to each other, such as the electronic control sensor module 200 or the brake valve module 300, independently, and avoid mutual interference between different functional modules.

[0048] At the same time, such as Figure 3 As shown, the third bracket 26 is located below the crossbeam, freeing up space for other chassis accessories and facilitating its own installation and maintenance. In some technical solutions, the third bracket 26 is suitable for installing the pipeline module 400. For example, pipes, wiring harnesses, or other related lines in the vehicle 1000 can be fixed and guided through the third bracket 26. This arrangement helps improve the neatness of the chassis area, avoids interference between pipes or wiring harnesses and other components, and also provides a certain degree of protection.

[0049] With the arrangement of this embodiment, not only will there be no interference between the brackets, but the space of the vehicle 1000 chassis can also be fully utilized, making the layout of the vehicle 1000 more reasonable and compact, which facilitates subsequent assembly and maintenance.

[0050] In some specific embodiments, the first bracket 22 includes a mounting body, on which a first mounting hole 221 is disposed, and the mounting body is used to fix and connect the functional module. Here, the first mounting hole 221 is used to fix the first bracket 22 to the crossbeam body 10. The mounting body is used to support and fix the corresponding functional module, such as the electronic control sensor module 200, etc.

[0051] In some specific embodiments, the second bracket 24 includes a first mounting plate 241 and two first support plates 242, with a second mounting hole 2411 provided on the first mounting plate 241. One end of each first support plate 242 is connected to both sides of the first mounting plate 241, and the other end extends in a direction away from the first mounting plate 241.

[0052] The symmetrical arrangement of the two first support plates 242 provides multiple connection points for the functional modules such as brake valve modules 300, and the force borne by the multiple connection points is transmitted more evenly to the first mounting plate 241, and then further to the crossbeam body 10, avoiding excessive local stress that could lead to deformation or damage.

[0053] Meanwhile, the outward extension of the first support plate 242 also provides a certain protective space for the installed functional modules, which helps to improve the stability of the functional modules during installation and the safety of their use.

[0054] Optionally, there are two pairs of third brackets 26, arranged at intervals along the length of the main body 10 of the crossbeam. Each pair includes two opposing third brackets 26, with one third bracket 26 corresponding to at least one first connecting screw hole 11 and the other third bracket 26 corresponding to at least one second connecting screw hole 12. This arrangement better covers the installation area on the side of the main body 10 of the crossbeam, allowing pipelines distributed on both sides of the crossbeam to find a suitable pair of third brackets 26 for fixing. This not only avoids the crossing and tangling of pipelines but also improves the neatness of the arrangement and the space utilization rate.

[0055] At the same time, the arrangement of each pair of third brackets 26 helps to distribute the stress, avoids all pipelines being placed on the third brackets 26 on one side, improves the stability and load-bearing capacity of the overall structure, and makes the installation of pipeline module 400 safer.

[0056] Each pair of third brackets 26 is simultaneously positioned above or below the main body of the crossbeam 10, and the embedding area 2620 within each pair of third brackets 26 extends along the longitudinal direction of the vehicle 1000. The pipeline module 400 is disposed within one of the two embedding areas 2620. These two embedding areas 2620 provide a longer support surface for the pipeline module 400, reducing its overhang and thus improving its stability during vehicle 1000 operation. Furthermore, centrally fixing the pipeline module 400 above or below the main body of the crossbeam 10, eliminating the need for dispersed placement in multiple locations, improves assembly efficiency and facilitates later inspection and maintenance. Please refer to [link / reference]. Figure 3 In some specific embodiments, the pipelines of functional modules such as the electronic control sensor module 200 and the brake valve module 300 are also centrally managed and fixed through the third bracket 26. This makes the entire chassis area more neat and orderly, avoids mutual interference between pipelines, and reduces the risk of pipeline loosening due to vibration or other external forces.

[0057] In some optional embodiments, both ends of the crossbeam body 10 are provided with lugs 14, which are arranged in pairs, each pair including two opposing lugs 14, and each lug 14 is provided with a third connecting screw hole 141. The third connecting screw hole 141 provides a connection point for other components, so that other components can also be installed on the crossbeam body 10, improving the integration of the integrated rear suspension assembly 100 and further reducing the number of parts.

[0058] Specifically, the integrated rear suspension assembly 100 also includes two thrust rods 30, which are located on both sides of the crossbeam body 10. Each thrust rod 30 is V-shaped and has a connecting part 31 at both ends. The two connecting parts 31 of each thrust rod 30 are connected to the third connecting screw holes 141 of the lugs 14 at both ends of the crossbeam body 10 by fasteners.

[0059] In the above technical solution, by using a unified third connecting screw hole 141 as the connection point, the thrust rod 30 is directly connected to the lifting lugs 14 at both ends of the crossbeam body 10, eliminating the need for an independent nut installation structure, reducing the number of parts, and improving the overall integration.

[0060] Meanwhile, the thrust rod 30 is integrated into the integrated rear suspension assembly 100, making the entire system structure more compact and unified.

[0061] Furthermore, a flange 15 is provided at the end of the main beam 10.

[0062] Optionally, the integrated rear suspension assembly 100 also includes two longitudinal beams 40, which are connected to the flange 15 one-to-one by fasteners.

[0063] Here, the flange 15 fastener connection method is adopted to avoid too many connection points caused by welding or installing connecting brackets, making the assembly between the longitudinal beam 40 and the transverse beam simpler and faster, while improving the structural tightness and reliability of use.

[0064] Furthermore, the crossbeam body 10 and the longitudinal beam 40 are connected by a flange 15, which provides a certain degree of versatility and flexibility. Different vehicle models can flexibly select the appropriate longitudinal beam 40 according to requirements such as wheelbase and chassis layout, without having to redesign the crossbeam body 10, which is conducive to platform-based development and large-scale production.

[0065] Moreover, the longitudinal beam 40 is integrated into the integrated rear suspension assembly 100, making the originally scattered structural components more concentrated and unified.

[0066] Alternatively, a sealed gas storage space is formed inside the main body 10 of the crossbeam, and the main body 10 of the crossbeam is provided with an inlet and outlet 13 that connects to the gas storage space.

[0067] In some specific embodiments, the main body 10 of the crossbeam has a cavity volume of nearly 10L, which can be used for air storage in the braking system.

[0068] This design eliminates the need for a separate air tank, avoiding the additional space required in the vehicle, and allows the main body of the crossbeam 10 to simultaneously perform multiple functions of load-bearing, connection, and air storage. This not only reduces the number of parts in the vehicle but also helps to further improve the system's integration level and space utilization.

[0069] Optionally, the main body 10 of the crossbeam can be a die-cast part.

[0070] It is worth noting that die-casting can relatively easily achieve complex structures while ensuring high dimensional accuracy and surface quality. Compared to traditional welded or assembled structures, die-casting helps to improve the strength and rigidity of the main beam 10.

[0071] Meanwhile, the use of die-cast crossbeam body 10 also helps to reduce the overall weight.

[0072] In addition, die-cast parts are suitable for mass production. The die-casting mold can be reused after a one-time investment, resulting in high production efficiency and good consistency.

[0073] Especially when the crossbeam body 10 has a sealed air storage space inside, the die-cast crossbeam body 10 has better sealing performance, reduces the risk of air leakage, and improves the reliability of the air supply to the braking system. At the same time, the connecting holes, connecting surfaces, and lugs 14 can be formed together during manufacturing, reducing subsequent processing steps, making the layout of the entire integrated rear suspension assembly 100 more compact, with fewer parts, and easier assembly.

[0074] A vehicle 1000 according to a second aspect embodiment of the present invention includes: a frame, an integrated rear suspension assembly 100, an electronic control sensor module 200, a brake valve module 300, and a pipeline module 400. The electronic control sensor module 200 is mounted on a first bracket 22. The brake valve module 300 is mounted on a second bracket 24. The pipeline module 400 is mounted on a third bracket 26, and is located above or below the crossbeam body 10. The integrated rear suspension assembly 100 adopts the integrated rear suspension assembly 100 of the first aspect embodiment of the present invention.

[0075] In the above technical solution, the electronic control sensor module 200, as part of the vehicle 1000 intelligent control system, has its installation position affecting the accuracy of signal acquisition. Fixing the electronic control sensor module 200 on the first bracket 22 not only facilitates positioning and installation but also effectively avoids vibration interference, improving the stability and reliability of the electronic control sensor module 200's operation.

[0076] Furthermore, the brake valve module 300 is one of the important components affecting the overall braking performance of the vehicle. Installing it on the second bracket 24 provides stable support and ensures smooth connection of the brake air circuit. At the same time, it also helps to simplify pipeline routing, reduce installation errors, and improve the response efficiency and safety of the braking system.

[0077] In addition, the pipeline module 400 typically includes components such as brake lines and electrical wiring harnesses. By integrating the pipeline module 400 onto the third bracket 26 and arranging it in conjunction with the upper and lower spaces of the crossbeam body 10, interference with other chassis components can be avoided, while making the pipeline routes neater and more orderly, and also easier to inspect and maintain.

[0078] All the above functional modules are installed through the brackets on the main body of the crossbeam 10, which eliminates a large number of independent mounting supports and connectors in the traditional structure, reduces the number of parts, improves the assembly efficiency of the whole vehicle, and also improves the layout coordination between the above functional modules so that they do not interfere with each other, thereby increasing the space utilization of the vehicle 1000.

[0079] In some specific examples, the integrated rear suspension assembly 100 is used, which reduces the number of parts, from 8 to 3, and the weight is reduced from 151kg to 99kg, achieving a weight reduction rate of about 34%. At the same time, the assembly process is simplified, improving production efficiency.

[0080] It is worth noting that the vehicle 1000 in this application can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. The vehicle type 1000 can be a commercial vehicle, such as an urban logistics vehicle or a medium-sized truck, or a heavy-duty tractor, such as a long-haul truck or a heavy-duty trailer, etc.

[0081] Alternatively, the frame includes two longitudinal beams 40, and the two ends of the crossbeam body 10 are provided with flanges 15 and are connected to the two longitudinal beams 40 by fasteners.

[0082] Here, the crossbeam body 10 and the longitudinal beam 40 are connected by a flange 15, which provides a certain degree of versatility and flexibility. Different vehicle models can flexibly select the appropriate longitudinal beam 40 according to requirements such as wheelbase and chassis layout, without having to redesign the crossbeam body 10, which is conducive to platform-based development and large-scale production.

[0083] Moreover, the longitudinal beam 40 is integrated into the integrated rear suspension assembly 100, making the originally scattered structural components more concentrated and unified.

[0084] The following is for reference. Figure 1 - Figure 3 The vehicle 1000 according to an embodiment of the present invention is described in detail with reference to a specific example. It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.

[0086] The integrated rear suspension assembly 100 includes: a crossbeam body 10, a first bracket 22, a second bracket 24, a third bracket 26, a thrust rod 30, and a longitudinal beam 40.

[0087] Reference Figure 1 The main body 10 of the crossbeam has multiple first connecting screw holes 11, multiple second connecting screw holes 12 and air inlet / outlet ports 13 in the middle section, and lifting lugs 14 at both ends.
