Description

Technical Field

[0001] This utility model relates to the field of hybrid transmission technology, and in particular to a front-wheel drive single-motor single-speed hybrid transmission. Background Technology

[0002] With the rapid growth of global car ownership, increasing pressure on energy, environment, and safety has accelerated the global trend towards energy conservation and electrification in the automotive industry. However, pure electric vehicles currently struggle to meet the demands of the market due to industry bottlenecks such as range anxiety, inadequate charging infrastructure, and the difficulty in achieving significant technological breakthroughs in power batteries in the short to medium term.

[0003] As a core component of the powertrain system of hybrid electric vehicles (HEV, PHEV), the hybrid transmission can improve the fuel economy and optimize the power performance of the vehicle under various operating conditions by controlling the power coupling between the engine and the electric motor in real time.

[0004] Many mid-to-large SUVs, MPVs, and pickup trucks, due to their size and weight, traditionally use a longitudinally mounted engine with rear-wheel drive or four-wheel drive. In the electrification process, these vehicles generally use a rear-wheel pure electric drive system, or combine it with a front-wheel pure electric drive system to form a four-wheel pure electric drive system. There are two ways to achieve hybridization: one is to retain the original rear-wheel or four-wheel pure electric drive system and add a range extender (comprising an engine and generator) independent of the vehicle's drive system to provide electricity for the vehicle's propulsion; the other is to retain the rear-wheel pure electric drive system and combine the front-wheel pure electric drive system and the range extender into a dual-motor front-wheel hybrid drive system. This type of dual-motor hybrid drive system includes dual-motor range-extended hybrid drive systems where neither the engine nor the generator participates in vehicle propulsion, as well as hybrid drive systems where the engine can participate in front-wheel drive in one or more gears.

[0005] Because the development and mass production of front-wheel drive hybrid transmissions with transverse engines were earlier and have become more widespread, some models with longitudinally mounted engines have been converted to a hybrid front-wheel drive system with transverse engines. However, it is more difficult to convert models with longitudinally mounted engines to a transverse engine system, so the longitudinal engine system needs to be retained.

[0006] Whether the engine is transverse or longitudinal, the implementation of dual-motor front-wheel hybrid drive involves three power sources: two motors and the engine. This results in a complex structure and high cost. If the two motors are combined into one, the generator can perform both power generation and drive functions, which can significantly reduce production costs and simplify the structure and control.

[0007] This hybrid transmission solution is a front-wheel drive single-motor single-speed hybrid transmission developed based on the above concept. Utility Model Content

[0008] The technical problem to be solved by this utility model is: in order to solve the problems existing in the prior art in the background art, a front-wheel drive single-motor single-speed hybrid transmission is provided, including two solutions: longitudinal engine and transverse engine.

[0017] Furthermore, the front drive axle differential is provided with a spiral bevel gear for main reduction and driven gear, which meshes with the spiral bevel gear for main reduction and driven gear on the front drive output shaft.

[0018] Furthermore, with the first clutch closed and the second clutch open, the engine's power is transmitted sequentially through the shock absorber, input flange, first clutch, input shaft, hybrid drive drive gear, and generator driven gear to the generator rotor shaft to drive the generator to generate electricity, which is the engine-driven generator power generation operating condition.

[0019] Furthermore, with the first clutch open and the second clutch closed, the generator's power sequentially passes through the generator rotor shaft, generator driven gear, hybrid drive drive gear, hybrid drive driven gear, second clutch, hybrid drive intermediate shaft, secondary transmission drive gear, secondary transmission driven gear, front drive output shaft, spiral bevel gear main reducer drive gear, spiral bevel gear main reducer driven gear, and front drive axle differential to drive the vehicle's front wheels. This is the generator single-gear drive mode. In the generator single-gear drive mode, the engine does not participate in operation.

[0020] Furthermore, with both the first and second clutches engaged, the engine's power sequentially passes through the shock absorber, input flange, first clutch, input shaft, hybrid drive drive gear, hybrid drive driven gear, second clutch, hybrid drive intermediate shaft, secondary transmission drive gear, secondary transmission driven gear, front drive output shaft, spiral bevel gear main reducer drive gear, spiral bevel gear main reducer driven gear, and front drive axle differential to drive the vehicle's front wheels, which is the engine single-gear drive mode.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0033] Example 1: Front-wheel drive single-motor single-speed hybrid transmission (engine longitudinally mounted)

[0034] like Figure 1 The front-wheel drive single-motor single-speed hybrid transmission (engine longitudinally mounted) shown is a front-wheel drive single-motor single-speed hybrid transmission formed together with the front-mounted engine on the basis that the vehicle already has rear-wheel pure electric drive. It can be used in conjunction with the rear-wheel pure electric drive system to realize the vehicle's single-speed four-wheel pure electric drive, range-extended drive and single-speed four-wheel hybrid drive.

[0035] Specifically, it includes:

[0036] Power source: Consists of an engine 100 with shock absorber 1 and a generator 200; wherein, the engine 100 is longitudinally mounted;

[0037] Gear clutch transmission system: It includes an input flange 2 and an input shaft 3 coaxially arranged with the engine 100, a generator rotor shaft 6, a hybrid drive intermediate shaft 7 and a front drive output shaft 10 arranged parallel to the input shaft 3;

[0038] It also includes a front drive axle differential 14, which is located below the longitudinally mounted engine 100 and is positioned perpendicular to the longitudinally mounted engine 100.

[0039] In this embodiment, the input flange 2 is splinedly connected to the shock absorber 1 on the engine 100; the input shaft 3 is connected to the input flange 2 through the first clutch C1, and a hybrid drive drive gear 4 is provided on the input shaft 3, which is fixedly connected to the input shaft 3.

[0040] In this embodiment, a driven gear 5 is provided on the generator rotor shaft 6. The driven gear 5 is fixed or splined to the generator rotor shaft 6, and the driven gear 5 meshes with the hybrid drive gear 4 on the input shaft 3.

[0041] In this embodiment, a secondary transmission drive gear 9, a second clutch C2, and a hybrid drive driven gear 8 are provided on the hybrid drive intermediate shaft 7; the secondary transmission drive gear 9 is fixedly connected to the hybrid drive intermediate shaft 7; the hybrid drive driven gear 8 is connected to the hybrid drive intermediate shaft 7 through the second clutch C2, and simultaneously meshes with the hybrid drive drive gear 4 on the input shaft 3.

[0042] In this embodiment, a secondary transmission driven gear 11 and a spiral bevel gear main reduction drive gear 12 are provided on the front drive output shaft 10; the secondary transmission driven gear 11 is splined connected to the front drive output shaft 10 and meshes with the secondary transmission drive gear 9 on the hybrid drive intermediate shaft 7; the spiral bevel gear main reduction drive gear 12 is fixedly connected to the front drive output shaft 10.

[0043] In this embodiment, a spiral bevel gear main reducer driven gear 13 is provided on the front drive axle differential 14, and the spiral bevel gear main reducer driven gear 13 meshes with the spiral bevel gear main reducer drive gear 12 on the front drive output shaft 10.

[0044] In this embodiment, the first clutch C1 is closed and the second clutch C2 is open. The power from the engine 100 is transmitted sequentially through the shock absorber 1, input flange 2, first clutch C1, input shaft 3, hybrid drive drive gear 4, and generator driven gear 5 to the generator rotor shaft 6. This drives the generator 200 to generate electricity, which is the engine-driven generator power generation operation mode.

[0045] In this embodiment, the first clutch C1 is open and the second clutch C2 is closed. The power of the generator 200 is transmitted sequentially through the generator rotor shaft 6, the generator driven gear 5, the hybrid drive drive gear 4, the hybrid drive driven gear 8, the second clutch C2, the hybrid drive intermediate shaft 7, the secondary transmission drive gear 9, the secondary transmission driven gear 11, the front drive output shaft 10, the spiral bevel gear main reduction drive gear 12, the spiral bevel gear main reduction driven gear 13, and the front drive axle differential 14 to drive the front wheels of the vehicle. This is the generator single-gear drive mode. In the generator single-gear drive mode, the engine 100 does not participate in the operation.

[0046] In this embodiment, both the first clutch C1 and the second clutch C2 are engaged. The power from the engine 100 sequentially passes through the shock absorber 1, input flange 2, first clutch C1, input shaft 3, hybrid drive drive gear 4, hybrid drive driven gear 8, second clutch C2, hybrid drive intermediate shaft 7, secondary transmission drive gear 9, secondary transmission driven gear 11, front drive output shaft 10, spiral bevel gear main reducer drive gear 12, spiral bevel gear main reducer driven gear 13, and front drive axle differential 14, driving the front wheels of the vehicle. This is the engine single-gear drive mode. In the engine single-gear drive mode, the generator 200 can idle or, by adjusting the positive and negative torque, can keep the engine 100 operating in a high fuel efficiency range.

[0047] In this embodiment, the opening and closing control of the first clutch C1 and the second clutch C2 can be controlled by hydraulic force or by electromagnetic force. The clutch structures of hydraulic control and electromagnetic force control are different, but their functions are the same, and the control methods are slightly different.

[0048] The operating mode of a front-wheel drive single-motor single-speed hybrid transmission in this embodiment is as follows:

[0049] Parking power generation: When the vehicle is stationary, the first clutch C1 is closed and the second clutch C2 is open. After the engine 100 is started using the power of the generator 200, the power of the engine 100 is transmitted through the shock absorber 1, the input flange 2, the first clutch C1, the input shaft 3, the hybrid drive gear 4, the generator driven gear 5, the generator and drive motor rotor shaft, and the generator 200 to generate electricity and charge the vehicle battery pack.

[0050] Range-extended drive: When the vehicle is in motion, the vehicle's drive is entirely provided by the rear-wheel pure electric drive system. At this time, the working state of this embodiment is basically the same as that of parking generator. The difference is that the power generated by the generator can be directly used for the rear-wheel pure electric drive system, and the surplus power can be used to charge the vehicle battery pack. When the vehicle needs a larger driving power, it can also work with the vehicle battery pack to provide power for the rear-wheel pure electric drive system.

[0051] Single-gear drive via generator: Under conditions of low to medium vehicle speed and a high battery charge, the first clutch C1 is open and the second clutch C2 is closed. The power from the generator 200 drives the vehicle through the generator rotor shaft 6, generator driven gear 5, hybrid drive drive gear 4, hybrid drive driven gear 8, second clutch C2, hybrid drive intermediate shaft 7, secondary transmission drive gear 9, secondary transmission driven gear 11, front drive output shaft 10, spiral bevel gear main reducer drive gear 12, spiral bevel gear main reducer driven gear 13, and front drive axle differential 14. The power used by the generator 200 comes from the vehicle's battery pack. Combined with the rear-wheel pure electric drive system, this achieves single-gear four-wheel pure electric drive at low to medium speeds.

[0052] Engine Single-Gear Drive: Under the premise of high-speed vehicle travel and efficient engine single-gear drive, both the first clutch C1 and the second clutch C2 are engaged. The power from engine 100 is transmitted through shock absorber 1, input flange 2, first clutch C1, input shaft 3, hybrid drive drive gear 4, hybrid drive driven gear 8, second clutch C2, hybrid drive intermediate shaft 7, secondary transmission drive gear 9, secondary transmission driven gear 11, front drive output shaft 10, spiral bevel gear main reducer drive gear 12, spiral bevel gear main reducer driven gear 13, and front drive axle differential 14 to drive the vehicle. This is the engine single-gear drive mode, combined with the rear-wheel pure electric drive system, to achieve single-gear four-wheel hybrid drive of the vehicle.

[0053] When the engine is driven in single gear, the generator / drive motor can idle, or be placed in generator or drive mode, depending on the vehicle's driving needs and engine operating conditions. This allows the engine to always operate in a higher efficiency range, improving vehicle performance while reducing fuel consumption.

[0054] The transition from range-extended drive to engine single-gear drive depends on the vehicle's speed. When the vehicle speed reaches the efficient single-gear drive range of the engine, the hydraulic clutch solution can directly engage the second clutch C2. The electromagnetic clutch solution requires adjusting the engine speed to be close to the suitable single-gear drive speed before engaging the second clutch C2 to execute engine single-gear drive.

[0055] The control process for transitioning from pure electric drive to engine-driven single-gear mode involves several steps. The hydraulic clutch solution can directly engage the first clutch C1, using the vehicle's driving power to start the engine and enter engine-driven single-gear mode. However, the electromagnetic clutch cannot directly engage engine-driven mode. It requires first transferring vehicle driving control to the rear-wheel pure electric drive system, opening the second clutch C2, and simultaneously controlling the generator 200 to reduce its speed to near zero. Then, the first clutch C1 is engaged, starting the engine 100 and executing the engine-driven generator power generation function, entering range-extended drive mode. The subsequent control method is the same as transitioning from range-extended drive mode to engine-driven single-gear mode.

[0056] Vehicle start-up: In situations where the vehicle is starting slowly or the power requirement is not high, the rear-wheel pure electric drive system performs the pure electric drive function. In this embodiment, it does not participate in the operation, and the power required by the rear-wheel pure electric drive system comes from the vehicle's battery pack. When a larger starting torque is required, and provided that the vehicle's battery pack has sufficient charge, the single motor in this embodiment can participate in driving the front wheels of the vehicle, achieving four-wheel pure electric drive start-up.

[0057] Engine start-stop: When the vehicle is parked, starting and stopping the engine requires the second clutch C2 to be open and the first clutch C1 to be closed, with the generator 200 driving and controlling the engine 100 to start and stop. When the vehicle is in motion, starting the engine requires only the hydraulic clutch to close the first clutch C1, using the vehicle's driving power to start the engine. The electromagnetic clutch requires handing over the vehicle's driving power to the rear wheel pure electric drive system and opening the second clutch C2 to reduce the speed of the generator 100 to near zero speed. Then, the first clutch C1 is closed, and the generator 200 is used to start the engine 100. When the vehicle speed is too low to operate in single-gear mode, the fuel supply to the engine 100 can be stopped and the first clutch C1 can be opened, allowing the engine to stop working automatically.

[0058] Reversing: The vehicle reverses as driven by the reverse rotation of the drive motor of the rear wheel pure electric drive system. If necessary, the generator-driven motor in this embodiment can also participate in the reversing drive.

[0059] Regenerative braking: Regenerative braking is achieved by converting the drive motor of the rear-wheel pure electric drive system into a generator state. In this embodiment, the generator 200 can also perform regenerative braking under single-speed pure electric drive and engine single-speed drive conditions.

[0060] Example 2: Front-wheel drive single-motor single-speed hybrid transmission (engine transversely mounted)

[0061] The functional control method of Embodiment 2 is completely the same as that of Embodiment 1, except that, to adapt to vehicles with transversely mounted engines, the parts on and after the hybrid drive intermediate shaft 7 have been adapted, specifically including:

[0062] Power source: Consists of an engine 100 with shock absorber 1 and a generator 200; wherein, the engine 100 is horizontally mounted;

[0063] The gear clutch transmission system includes an input flange 2 and an input shaft 3 coaxially mounted with the engine 100, a generator rotor shaft 6 and a hybrid drive intermediate shaft 7 parallel to the input shaft 3.

[0064] It also includes a front drive axle differential 14, which is arranged parallel to the transversely mounted engine 100.

[0065] The hybrid drive intermediate shaft 7 is provided with a main reduction drive gear 15, a second clutch C2 and a hybrid drive driven gear 8, and the main reduction drive gear 15 is fixedly connected to the hybrid drive intermediate shaft 7.

[0066] The front drive axle differential 14 is provided with a main reduction driven gear 16, which meshes with the main reduction drive gear 15 on the hybrid drive intermediate shaft 7;

[0067] After the power from the engine 100 and generator 200 is transmitted to the hybrid drive intermediate shaft 7, the front wheels of the vehicle are driven through the main reducer drive gear 15, the main reducer driven gear 16, and the front drive axle differential 14.

[0068] Example 2 and Example 1 are adaptive adjustments corresponding to two engine configurations: longitudinal and transverse engine configurations, respectively, and have the same functions as Example 1. Their operating modes are completely identical to those of Example 1.

[0069] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
