Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to an integrated mounting bracket for a commercial vehicle drive system, a drive module, and a commercial vehicle. Background Technology

[0002] In the construction of commercial vehicles, the drive system at the rear of the chassis is a critical component, comprising numerous parts such as the rear drive axle, drive shaft, and reducer. Currently, these components are mostly installed using a decentralized mounting method, with each component individually connected to the chassis frame. This installation method has significant drawbacks. On the one hand, the component layout is rather cluttered, occupying a considerable amount of chassis space and hindering the rational arrangement of other chassis components, thus affecting the overall space utilization of the vehicle. On the other hand, decentralized installation makes it difficult to guarantee the relative positional accuracy between components. During vehicle operation, factors such as vibration can easily cause the connections between components to loosen, affecting the stability and reliability of the drive system, and consequently adversely impacting the vehicle's driving performance and safety.

[0003] Meanwhile, rear exterior components of commercial vehicles, such as side skirts and rear bumpers, are typically mounted separately on the chassis, lacking coordination with the installation of drive system components. This not only increases assembly steps and time, reducing production efficiency, but also may cause spatial interference between exterior components and drive system components, affecting the vehicle's appearance and performance. Furthermore, decentralized installation makes subsequent maintenance and repair work more difficult, hindering rapid troubleshooting and resolution.

[0004] Therefore, there is an urgent need for a modular mounting bracket for commercial vehicle drive systems. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The purpose of this invention is to provide a commercial vehicle drive system integrated mounting bracket, drive module, and commercial vehicle to solve the problems existing in the prior art and to make the drive system integrated modular.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Please refer to the following: Figures 1-4As shown, a commercial vehicle drive system integrated mounting bracket is provided, including a first longitudinal beam 1, a second longitudinal beam 2, a first support beam 3, and a second support beam 4. The first longitudinal beam 1 and the second longitudinal beam 2 are arranged in parallel. Both the first longitudinal beam 1 and the second longitudinal beam 2 are provided with a first connecting part for connecting to the drive axle 8. The first longitudinal beam 1 and the second longitudinal beam 2 are both connected to the first support beam 3 and the second support beam 4, forming a stable rectangular frame structure. The first support beam 3 is provided with a second connecting part 6 for connecting to the side skirt 10. The second support beam 4 is provided with a third connecting part for connecting to the surround plate 11. The first longitudinal beam 1 and the second longitudinal beam 2 are provided with a fourth connecting part for connecting to the vehicle frame. Through the arrangement of the longitudinal beams and support beams, the integrated installation of the drive axle 8, the side skirt 10, and the surround plate 11 can be completed. At the same time, after the drive axle 8 is connected to the drive shaft and reducer and other components, the integration of the drive system is realized.

[0023] A separate area can be designated as the first connecting part on the first longitudinal beam 1 and the second longitudinal beam 2, or a block-shaped, plate-shaped, or rod-shaped structure can be welded or bolted to serve as the first connecting part, or the entire first longitudinal beam 1 and the second longitudinal beam 2 can serve as the first connecting part.

[0024] The first connecting part is connected to the drive axle 8 by bolting, which can ensure both connection strength and ease of installation and disassembly. In one embodiment, the first connecting part is provided with multiple mounting holes 5, which are used to bolt to the mounting base 9 of the drive axle 8. The design of multiple mounting holes 5 allows the drive axle 8 to be installed in a specific mounting hole 5 according to the required installation position. At the same time, the position of the drive axle 8 can be adjusted by switching the mounting holes 5 connected to the drive axle 8.

[0025] Multiple mounting holes 5 are arranged both horizontally and vertically to expand the adjustment range of the drive axle 8.

[0026] Since both the side skirt 10 and the surrounding plate 11 are plate-shaped structures, the second connecting part 6 and the third connecting part are designed to be rod-shaped structures. The longer structure is used to connect with the plate-shaped side skirt 10 and the surrounding plate 11 to improve the connection strength. The second connecting part 6 can be a structure that is welded or bolted separately to the first support beam 3, or it can be an integral structure with the first support beam 3. The third connecting part can be a structure that is welded or bolted separately to the second support beam 4, or it can be an integral structure with the second support beam 4.

[0027] Multiple first support beams 3 can be provided, and the multiple first support beams 3 are arranged along the length direction of the first longitudinal beam 1 to adapt to the longer side skirt 10 and improve the connection stability with the side skirt 10.

[0028] In one embodiment, the second connecting part 6 is bolted to the mounting bracket 7 of the side skirt plate 10, and the third connecting part is bolted to the mounting bracket 7 of the surrounding plate 11. The bolted connection method can ensure both connection strength and ease of installation and disassembly.

[0029] The mounting bracket 7 can be an L-shaped plate. One side of the L-shaped plate is welded or bolted to the side skirt plate 10 or the surrounding plate 11, and the other side is bolted to the second connecting part 6 or the third connecting part. The connection part is only bolted to the L-shaped plate, which can improve the convenience of installation and disassembly when replacing the side skirt plate 10 or the surrounding plate 11 in subsequent maintenance.

[0030] In one embodiment, both ends of the first support beam 3 are provided with a U-shaped structure. The U-shaped structure can effectively improve the structural strength of the first support beam 3. One end of the U-shaped structure near the first longitudinal beam 1 is connected to the first longitudinal beam 1, and the other end of the U-shaped structure near the second longitudinal beam 2 is connected to the second longitudinal beam 2. Specifically, the vertical rod of the U-shaped structure near the longitudinal beam is connected to the longitudinal beam. The connection method is bolt connection or welding. Alternatively, the vertical rod can be extended downwards for a certain length to make contact with the longitudinal beam with a larger contact surface, thereby improving the stability of the installation.

[0031] In one embodiment, since the size of the surrounding plate 11 is large, the second support beam 4 is designed as a rectangular frame structure. The two longitudinal bars of the second support beam 4 are respectively connected to the first longitudinal beam 1 and the second longitudinal beam 2, and the two horizontal bars are connected to the surrounding plate 11. The connection strength can be improved by connecting the two horizontal bars to the surrounding plate 11, and the two longitudinal bars correspond to the first longitudinal beam 1 and the second longitudinal beam 2 respectively, thereby improving the connection strength with the longitudinal beams.

[0032] Since the surface of the surround plate 11 corresponding to the direction of vehicle travel has a certain curvature, the two crossbars of the second support beam 4 are staggered, with the vertical surface of the lower crossbar located on the side of the vertical surface of the upper crossbar closer to the first longitudinal beam 1, in order to adapt to the shape of the surround plate 11.

[0033] Both the first longitudinal beam 1 and the second longitudinal beam 2 are vertical plate-like structures. At the same time, the bottom ends of the first longitudinal beam 1 and the second longitudinal beam 2 are bent inward to form horizontal strip-like structures. The two vertical members of the second support beam 4 include a horizontal section, a vertical section, and an L-shaped bending section. The vertical section is connected to the lower horizontal member, the horizontal section is connected to the upper horizontal member, and the two ends of the L-shaped bending section are connected to the free ends of the vertical section and the free ends of the horizontal section, respectively. The horizontal part of the L-shaped bending section is welded or bolted to the strip-like structure to realize the connection between the vertical member and the longitudinal beam.

[0034] In one embodiment, the fourth connection part is a block, plate, or rod structure that is welded or bolted to the longitudinal beam separately. Alternatively, a region on the longitudinal beam can be selected directly as the fourth connection part. The fourth connection part is provided with multiple mounting bolt holes and positioning pin holes so that the integrated commercial vehicle drive system mounting bracket can be quickly and accurately connected to the vehicle frame.

[0035] In the actual process of connecting the integrated mounting bracket of the commercial vehicle drive system with the drive axle 8, side skirt 10 and surround plate 11, after adjusting the position of the drive axle 8, align the mounting seat 9 of the drive axle 8 with the mounting holes 5 of the first longitudinal beam 1 and the second longitudinal beam 2, insert high-strength bolts into the bolt holes of the mounting seat 9, and fasten the mounting seat 9 of the drive axle 8 to the longitudinal beam to ensure a firm connection; after completing the connection of the drive axle 8, connect the side skirt 10 and surround plate 11 to the support beam.

[0036] This utility model also provides a drive module using the aforementioned commercial vehicle drive system integrated mounting bracket, including a drive axle 8, side skirts 10, surround plates 11, and a commercial vehicle drive system integrated mounting bracket. The drive axle 8 is connected to the first longitudinal beam 1 and the second longitudinal beam 2, the side skirts 10 are connected to the first support beam 3, and the surround plates 11 are connected to the second support beam 4, forming an integrated modular structure for direct connection to the vehicle frame during vehicle assembly. During the connection process, the commercial vehicle drive system integrated mounting bracket, which houses the drive system components, is moved to the frame mounting position. The frame is inserted into the commercial vehicle drive system integrated mounting bracket, and initial positioning is achieved through locating pin holes. Then, mounting bolts are used to securely connect the commercial vehicle drive system integrated mounting bracket to the frame, ensuring a firm connection. During installation, measuring tools are used to check the installation position of the commercial vehicle drive system integrated mounting bracket to ensure that the installation accuracy meets design requirements.

[0037] This utility model also provides a commercial vehicle that uses the above-mentioned drive module. The vehicle frame is connected to the drive module, which enables the connection between the drive axle 8 and the vehicle frame.
