[0044] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Terminology in this application:

[0046] MG is an abbreviation for Motor-Generator, referring to a combined motor and generator unit.

[0047] This solution addresses the integrated, modular, and universal design requirements of hybrid vehicle powertrain systems by proposing a highly integrated hybrid powertrain drive unit module structure. This structure overcomes the drawbacks of traditional vehicle powertrain designs, which involve dispersed layouts, independent component assembly, and poor adaptability. It deeply integrates six core components—engine, power-split hybrid drive assembly, suspension system, wheel-side drive axle, wheel-side reducer, and chassis system—to form a complete, integrated, independently assembleable, and rapidly expandable powertrain drive module.

[0048] This module adopts an overall layout of longitudinally mounted engine with direct drive, integrated hybrid powertrain with axle and transmission, wheel-side progressive drive, and suspension connection, constructing a compact, highly efficient, stable, and widely adaptable rear-drive load-bearing system. Compared to traditional hybrid powertrain layouts, this modular design significantly simplifies the vehicle assembly process, reduces overall vehicle R&D and manufacturing costs, and is compatible with hybrid models of different wheelbases and body structures. It possesses strong platform expansion capabilities, effectively improving the reliability, maintainability, and iterative upgrade efficiency of the vehicle's powertrain system.

[0049] This solution will elaborate on the overall layout of the modules, the structural design of each subsystem, the power transmission path, the connection and assembly method, the core advantages of modularization, and the application scenarios for vehicle adaptation, providing complete technical support for the platform-based design of hybrid vehicle powertrain systems.

[0050] This powertrain unit abandons the traditional separate installation structure of power components, adopting a multi-system integrated modular structure. It integrates the three major functional systems—power output core (engine, hybrid drive assembly), power transmission core (wheel-side drive shaft, wheel-side reducer), and load-bearing support core (suspension system, frame system)—into an independent, complete, and functionally closed-loop rear-drive load-bearing module. All core components are precisely connected mechanically, mounted, and spatially matched to form an integrated unit, enabling overall pre-assembly, overall hoisting, and overall disassembly, completely different from the traditional production mode of assembling vehicle parts one by one.

[0051] The overall integration logic of this module is based on "centralized power output, hierarchical transmission, overall load-bearing, and shock absorption". All power components are centrally located in the core area at the rear of the frame. The suspension system achieves shock absorption isolation from the vehicle body, and the frame system achieves overall load-bearing and fixation. This ensures both the continuity and stability of power transmission, as well as the comfort and structural reliability of the vehicle.

[0052] The core power source of this module adopts a longitudinal engine mounting configuration. The engine is arranged longitudinally along the front-rear direction of the vehicle. Compared with the transverse layout, the longitudinal structure has the advantages of a straight power transmission path, low transmission loss, compact axial structure, and uniform stress distribution, making it more suitable for the power output requirements of high-power hybrid vehicles.

[0053] The engine output is rigidly and directly connected to the hybrid drive assembly via a dedicated flywheel housing, eliminating intermediate transmission components. The flywheel housing, made of high-strength cast aluminum, is lightweight, highly rigid, and deformation-resistant, effectively bearing the engine's output torque while ensuring precise positioning of the engine and hybrid assembly, guaranteeing their coaxiality and reducing vibration, noise, and power loss during power transmission. This direct connection between the engine and hybrid assembly forms the core power unit, providing a stable power input foundation for subsequent power splitting, transmission, and wheel-end output.

[0054] The core component of this solution, the hybrid drive assembly, adopts an integrated structure combining the transmission and drive axle. Breaking away from the traditional separate design of the gearbox and drive axle, it integrates the housing, transmission box, and drive axle housing into a single cast structure. This integrated structure significantly reduces the number of parts, eliminating separate connecting flanges, gaskets, fixing bolts, and other connecting components, effectively reducing the overall weight of the assembly and minimizing its space occupation. Simultaneously, it completely solves the industry pain points of separate structures, such as easy oil leakage, insufficient rigidity, and large coaxiality deviations.

[0055] The hybrid drivetrain features a highly integrated design, housing all core functional components such as the generator MG1, drive motor MG2, multi-stage shift transmission system, planetary gear set power splitting mechanism, main reducer, and differential system. It integrates power generation, drive, transmission, torque splitting, and differential steering functions into one integrated system. This integrated internal structure can intelligently switch between series, parallel, and hybrid operating modes according to the vehicle's driving conditions, perfectly adapting to all driving scenarios including low-speed crawling, medium-speed cruising, high-speed acceleration, and heavy-load climbing, achieving a balance between high-efficiency energy saving and powerful performance.

[0056] This module adopts a power transmission logic of "centralized output from the core power unit, symmetrical power distribution on both sides, progressive deceleration at the wheel ends, and ground-based drive at the wheel ends." The overall transmission path is clear, symmetrical, and balanced, effectively ensuring consistent power output to the left and right wheels and improving the vehicle's driving stability and handling. The entire power transmission system has no redundant transmission structure, resulting in high transmission efficiency, fast response speed, and precise execution of the vehicle controller's power output commands.

[0057] The first step is power output. The engine 100 is arranged longitudinally and outputs mechanical power during operation. This power is directly transmitted to the hybrid drive assembly 102 through the flywheel housing 101 at the output end, completing the input of mechanical power. At the same time, the MG1 generator inside the hybrid assembly can generate electricity driven by the engine according to the operating conditions, realizing the conversion of mechanical energy into electrical energy to replenish the power battery or power the MG2 drive motor.

[0058] The second step is power integration and regulation. After the power enters the hybrid drive assembly 102, it is integrated, torque is adjusted, and speed is matched through the internal power splitting mechanism, transmission system, and differential system. The operating mode is intelligently switched according to driving conditions: series mode is used for low-speed conditions, with the engine generating electricity and the motor driving; parallel mode is used for medium- and high-speed constant speed conditions, with the engine and motor jointly outputting power; and hybrid mode is used for rapid acceleration and climbing conditions to maximize the release of the vehicle's power performance. At the same time, the differential system realizes differentiated power distribution to the left and right wheels to meet the vehicle's steering needs.

[0059] The third step is the dual-side power split output. The power after being regulated by the hybrid powertrain is split outward through the output half-shafts 103 symmetrically arranged on both sides of the hybrid drive assembly 102. The two half-shafts have the same specifications and symmetrical lengths to ensure that there is no deviation in the power transmission between the left and right sides.

[0060] The fourth step is wheel-side power transmission and reduction. The output half-shaft 103 is rigidly connected to the wheel-side drive shaft 104, transmitting power to the wheel-side drive shaft. As an intermediate power transmission component, the wheel-side drive shaft possesses high strength, torsional resistance, and fatigue resistance, enabling it to stably transmit high torque power, ultimately delivering the power to the wheel-side reducer 105. The wheel-side reducer adopts a planetary gear reduction structure, which can further amplify the output torque and reduce the output speed, adapting to the vehicle's heavy-load and hill-climbing driving needs, and significantly improving the overall vehicle power performance.

[0061] The fifth step is wheel-end ground drive. After being reduced in speed and torque by the wheel-side reducer, the power is precisely transmitted to the wheel end 106, driving the wheel to rotate and enabling the vehicle to move, thus completing the entire power transmission closed loop.

[0062] This power drive unit is not simply a power transmission module, but an integrated system that combines load-bearing, shock absorption, and support functions. The entire core power unit (engine + hybrid powertrain + wheel-side drive mechanism) is connected to the suspension system (control arms 108 and shock absorbers 110) and the frame system 109 through multiple mounts 107, forming a complete rear-drive load-bearing system module. The mounts, suspension, and frame work together to perform the core functions of shock absorption, dynamic support, and overall load-bearing, respectively.

[0063] The module employs a multi-point mounting arrangement. Based on the powertrain's weight distribution, vibration frequency, and stress characteristics, multiple sets of high-performance rubber mounts are placed at key locations such as the front of the engine, the left and right ends of the hybrid powertrain, and the rear end. The mounts are made of highly elastic, aging-resistant, and high-damping rubber, combined with a high-strength metal frame. This effectively isolates high-frequency vibrations and noise generated by the engine and electric motor during operation, preventing powertrain vibrations from being transmitted to the vehicle body and significantly improving the overall NVH performance. Simultaneously, the mounts buffer impacts from the road surface during vehicle operation, protecting core powertrain components from damage caused by bumps and shocks, and extending the overall lifespan of the module.

[0064] The suspension system adopts a dedicated structure adapted to the modular power unit, precisely matching the wheel-side drive mechanism and frame system. It can effectively support the overall weight of the power module while providing wheel guidance, cushioning, and shock absorption functions. Reasonable clearances are reserved between the suspension system and the wheel-side drive shaft and wheel-side reducer to ensure no interference between the transmission components and the suspension during vehicle bumps and turns, guaranteeing driving stability.

[0065] The chassis system, as the load-bearing base of the entire module, adopts a high-strength stamped and welded structure, featuring high load-bearing capacity, deformation resistance, and high rigidity. The chassis is pre-installed with standardized suspension mounting points and suspension fixing points; all mounting points use unified standardized interfaces to ensure the assembly precision of the power module. The chassis can bear the entire load of the power module while evenly distributing the load to the entire vehicle body, achieving a stable integration of the power module and the vehicle as a whole.

[0066] In the mass production assembly system of the whole vehicle, this modular power drive unit can be used independently as a universal standard power unit. All performance tests are completed before the module leaves the factory, including tests on key indicators such as power transmission efficiency, suspension damping performance, differential steering accuracy, assembly sealing performance, and stability during operating conditions, to ensure that the module meets the standards upon leaving the factory.

[0067] During vehicle assembly, the modular units only need to be precisely aligned with the pre-reserved mounting points on the vehicle frame. Assembly is then completed by bolting, wiring, and pipe connections. The assembly process is simple and has a high tolerance for errors. For models with different wheelbases, adaptation can be achieved quickly by adjusting the output half-shaft length, suspension travel, and frame adapter mounts. For models with different power requirements, the power parameters can be differentiated by calibrating the hybrid powertrain's operating logic and adjusting the wheel-side reduction ratios to meet the varying power needs of high- and low-spec models.

[0068] Meanwhile, this modular structure facilitates subsequent technology iteration and upgrades. Based on a unified modular architecture, motor power, engine parameters, and electronic control strategies can be upgraded without modifying the overall vehicle architecture, greatly improving the speed of model iteration and product competitiveness, and adapting to the current industry trend of rapid iteration of hybrid vehicles.

[0069] Please refer to Figures 1-2 The overall technical solution in this application is as follows:

[0070] The structure integrates the engine, power-split hybrid drive system, suspension system, wheel-side drive shaft, wheel-side reducer, and frame system into a complete power drive unit module.

[0071] The engine is longitudinally mounted and directly connected to the hybrid drive assembly via the flywheel housing.

[0072] The wheel-side drive shaft works in conjunction with the wheel-side reducer to achieve the power transmission path for wheel-end drive.

[0076] Specifically, the engine 100 is arranged longitudinally, and its output end is connected to the hybrid drive assembly 102 through the flywheel housing 101. The hybrid drive assembly 102 integrates the generator MG1, the drive motor MG2, the gear shifting system, the differential system, etc., and can realize multiple working modes such as series, parallel, and hybrid operation according to the working conditions.

[0077] The output ends on both sides of the hybrid drive assembly 102 are respectively connected to the output half shaft 103, the output half shaft 103 is connected to the wheel-side drive shaft 104, and the wheel-side drive shaft 104 transmits power to the wheel end 106 through the wheel-side reducer 105.

[0078] The entire power unit is connected to the suspension system (control arm 108 and shock absorber 110) and the frame system 109 via multiple mounts 107, forming a complete rear-drive load-bearing system module that can be independently assembled and disassembled.

[0079] In actual vehicle assembly, this module can be used as a standard unit to adapt to hybrid vehicles with different wheelbases and body shapes, enabling rapid expansion and installation.

This significantly reduces the number of vehicle parts, simplifies piping and wiring, effectively compresses the space occupied by the powertrain, and reserves ample space for the vehicle's cabin and battery pack. Simultaneously, the integrated structure improves overall structural rigidity, reduces transmission clearance, and increases power transmission efficiency by 5%-8% compared to traditional split structures.

[0106] This power drive unit is an independent, standardized module that can be pre-assembled, debugged, and tested entirely in the workshop, eliminating the need for individual component assembly on the vehicle assembly line.

Furthermore, the module can be completely disassembled for later vehicle repair, maintenance, and troubleshooting, greatly enhancing maintenance convenience.

[0107] This modular power unit adopts standardized interfaces, standardized installation points, and a universal structural design, making it suitable for use in various vehicle models. It can be flexibly adapted to hybrid passenger vehicles and commercial vehicles with different wheelbases, body sizes, and positioning. Vehicle adaptation can be completed simply by fine-tuning the suspension stiffness, suspension damping, and transmission matching parameters according to the vehicle parameters, without the need to redevelop the entire power system. This significantly reduces the development cycle and cost of new vehicles for automakers and has extremely high platform reuse value.

[0108] Leveraging the multi-mode operating logic of the hybrid powertrain and combined with a wheel-side reduction and torque-boosting structure, this module perfectly adapts to all road conditions and driving requirements.
