[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0031] Example 1:

[0032] like Figure 1 As shown, the system includes an engine 1, a generator 2, a drive motor 3, an engine input shaft gear 4, an engine connecting shaft gear 5, a clutch 6, a drive input shaft gear 7, a drive output shaft gear 8, a driving spiral bevel gear 9, a driven spiral bevel gear 10, a front axle power output shaft 11, a rear axle power output shaft 12, a front drive axle 13, and a rear drive axle 14. The crankshaft of the engine 1 is connected to the generator 2. The other side of the crankshaft meshes with the engine connecting shaft gear 5 through the engine input shaft gear 4. The engine connecting shaft gear 5 is connected to one end of the clutch 6, and the other end of the clutch 6 is connected to the drive input shaft gear 7. The drive input shaft gear 7 is poweredly connected to the drive motor 3. The drive motor 3 meshes with the drive input shaft gear 7 through the drive output shaft gear 8. The drive output shaft gear 8 is coaxially arranged with the driving spiral bevel gear 9. The driving spiral bevel gear 9 meshes with the driven spiral bevel gear 10. The front axle power output shaft 11 and the rear axle power output shaft 12 are both connected to the driven spiral bevel gear 10 to transmit power to the front drive axle 13 and the rear drive axle 14.

[0033] The hybrid scheme arrangement cancels the traditional CVT transmission, adopts gear transmission, improves transmission efficiency and reliability, saves maintenance cost, the crankshaft of the engine 1 is connected with the generator 2, the other side of the crankshaft is connected with the input gear, and the input gear is connected with the built-in clutch in the driving motor 3 through gear transmission, the clutch is used as the engine intervention power transmission and disconnection. Since the ATV axial space requirement is shorter, the engine 1 and the driving motor 3 are arranged in parallel, the clutch 6 is built in the rotor of the driving motor 3, and the axial space is further reduced; since the all-terrain vehicle has high power requirement, four-wheel drive is usually adopted, the output end of the hybrid system adopts the spiral bevel gear, the power is output to the front and rear drive axles to realize the four-wheel drive function; the specific power mode is as follows:

[0034] Pure electric drive: the clutch 6 is disconnected, the engine 1 and the generator 2 are not started, the power is taken from the vehicle power battery, the driving motor 3 drives the gear pair to transmit the power to the driving spiral bevel gear 9 to drive the driven spiral bevel gear 10, and the driving force is transmitted to the front drive axle 13 and the rear drive axle 14 through the front axle power output shaft 11 and the rear axle power output shaft 12; the front axle power output shaft 11 and the rear axle power output shaft 12 are in transmission connection with the driven spiral bevel gear 10; since the motor has the characteristics of low speed and large torque, the low speed and large torque climbing in the all-terrain vehicle can be realized; the engine running time is reduced, and the fuel consumption is saved;

[0035] Engine series range increasing mode: the clutch 6 is disconnected, the generator 2 starts the engine 1 to run, the engine 1 is started to stably generate power, and the electric energy generated by the generator 2 is directly provided for the driving motor 3 to reduce the power consumption of the power battery, while meeting the power demand of the driving motor 3, the excess electric energy can be charged into the power battery; this working condition is mostly light load operation; since the ATV all-terrain vehicle itself requires a lightweight vehicle body, the complex working conditions of off-road and jumping require high performance and capacity of the battery, and the charging facilities are not complete in the wild, so the range increasing power generation function is provided, the capacity requirement of the power battery is further reduced, and a small capacity battery can be adopted, which is systematic optimization for the lightweight, safety and cost of the whole vehicle;

[0036] Engine parallel drive mode: the clutch 6 is combined, the engine 1 is started, the engine power and the driving motor 3 power are connected in parallel to drive the output shaft, and the power is transmitted to the front and rear drive axles; this mode is usually high-power output; when the vehicle speed reaches medium and high speed, the torque output of the driving motor 3 is controlled to maintain the engine power direct drive as much as possible, the engine is in high efficient drive at this time, the high speed electric energy consumption of the driving motor 3 is reduced, and the surplus power of the engine can also make the generator 1 generate power to charge the battery to supplement the power of the battery;

[0037] Parking power generation mode: clutch 6 is disconnected, drive motor 3 stops working, engine 1 drives generator 2 to generate electricity to charge power battery; due to the lack of charging facilities in the wild, the charging time is long, and the pure electric charging is more inconvenient; the hybrid system can realize parking power generation, greatly make up for the pain point of off-road vehicle power supply in the wild, and also increase the experience

[0038] Escape or limit mode: when complex extreme road conditions appear in the wild and need to escape, the generator 2 can be used as a drive motor for a short time, when the power battery power meets the power output, the engine 1 and the generator 2 and the drive motor 3 can realize three power parallel driving for a short time, the maximum power of the system is output to the front and rear axle wheels, and the vehicle limit off-road or escape is realized;

[0039] Brake energy recovery: when the vehicle decelerates, the drive motor 3 is controlled by negative torque and enters the power generation mode, directly recovers and converts the vehicle kinetic energy into electric energy to recharge the power battery, realizing brake energy recovery;

[0040] Example two:

[0041] As shown in the accompanying Figure 2 For the single-sided output of the all-terrain vehicle engine, the generator 2 and the clutch 6, the engine input shaft gear 4 are arranged at the original CVT position; the generator 2 is directly connected with the engine 1, the clutch 6 is embedded in the rotor of the generator 2, the rotor of the generator 2 is connected with one end of the clutch 6, and the engine input shaft gear 4 is connected with the other end of the clutch 6;

[0042] Its advantages are that the engine is less changed, the output space of the original CVT gearbox is borrowed, the generator 2 and the clutch 6 are integrated, the spline shaft structure is arranged on the same side, which is more compact, and the lubrication structure and method are more convenient; the power mode is similar to that of example one;

[0043] Example three:

[0044] As shown in the accompanying Figure 3 For the straddle ATV all-terrain vehicle, the vehicle body is narrow, and the axial distance requirement of the engine is shorter, so the structure is more suitable for the arrangement of the extremely short axial output requirement; the engine 1 crankshaft is directly connected with the engine input shaft gear 4, the engine connecting shaft gear 5 is connected with the generator 2, the generator 2 is connected with one end of the clutch 6, the other end of the clutch 6 is connected with the drive input shaft gear 7, the drive input shaft 7 is connected with the drive motor 3, and the power is output to the front drive axle 13 and the rear drive axle 14 through the power output shaft gear 8, the driving helical bevel gear 9 and the driven helical bevel gear 10;

[0045] The advantages are that the engine does not need to be modified, the original crankshaft power output structure is connected with the hybrid system, and the power is transmitted through the gear instead of the CVT belt or steel belt; at the same time, the double motors are coaxial and arranged in parallel with the engine, which further optimizes the axial space and engine modification, has wider adaptability, and has higher efficiency and reliability compared with the CVT transmission.

[0046] Example Four

[0047] As shown in the accompanying Figure 4 For a wider all-terrain vehicle, the drive motor 3 can also be coaxially arranged with the engine 1; one end of the engine 1 crankshaft is connected with the generator 2, the other end of the engine crankshaft is connected with one side of the clutch 6, the other side of the clutch 6 is connected with the drive motor 3, and the power is output to the front and rear drive axles through the gear pair transmission;

[0048] The advantages are that the structure adopts coaxial arrangement of double motors and engine, has high integration, independent transmission system, occupies smaller X-direction size of the whole vehicle, and is more convenient for arranging the power battery for the hybrid vehicle;

[0049] The above implementation schemes are mainly used for straddle-type ATV hybrid vehicles, which are small and light in weight, and the engine usually adopts a 500cc / 1000cc single-cylinder or two-cylinder engine, the power system adopts an engine-centered four-wheel drive and front and rear drive axle structure, and is suitable for straddle-type vehicles with short axial distance.

[0050] For the wider all-terrain vehicle UTV and SSV side-by-side vehicle body, the power system usually adopts an engine-rear four-wheel drive structure, and for such UTV and SSV all-terrain vehicles, the power system is similar to the traditional automobile structure, the hybrid system will adopt an integrated differential and divider, the rear drive axle 14 and the rear axle power output shaft 12 are cancelled, the rear wheels adopt a half shaft output mode, the differential and the divider are integrated in the hybrid box, the power is output to the front drive axle through the spiral bevel gear, and the four-wheel drive function is realized, the structure is further highly integrated, the power system structure is more compact, the size and weight are small, and the procurement cost and weight of the rear drive axle are reduced, and the specific implementation is as follows:

[0051] Example Five

[0052] As shown in the accompanying Figure 5As shown, the output of engine 1 is connected to one end of clutch 6, and the other end of clutch 6 is connected to drive motor 3. Clutch 6 can be embedded in the rotor of drive motor 3, which can reduce the axial size. The crankshaft on the other side of engine 1 is connected to generator 2. Engine input shaft gear 4 and engine connecting shaft gear 5 are connected to drive motor 3 output shaft. Drive input shaft gear 7 is connected to drive motor 3 connecting shaft gear 5. Drive output shaft gear 8 transmits power to main differential gear 15, which is then transmitted to the rear wheels through left and right half shafts 16 and 17. At the same time, drive spiral bevel gear 9 is connected to drive output shaft gear 8. Power is transmitted through drive spiral bevel gear 9 to driven spiral bevel gear 10 and front axle power output shaft 11 to drive front drive axle 13 to drive the front wheels, realizing four-wheel drive function.

[0053] Its advantages are: the hybrid structure adopts a rear-mounted four-wheel drive, which is highly integrated with the rear drive axle differential and transfer case, resulting in fewer parts and reduced overall vehicle cost. At the same time, the rear wheels directly drive the wheels through the half-shaft, resulting in higher transmission efficiency and improved drive and braking energy recovery efficiency of the power system. The hybrid powertrain is smaller and lighter, which facilitates vehicle layout and achieves overall vehicle lightweighting.

[0054] Example 6:

[0055] As attached Figure 6 As shown, the output of engine 1 is connected to generator 2, the output of generator 2 is connected to one end of clutch 6, the other end of clutch 6 is connected to engine input shaft gear 4, and together with the output shaft of drive motor 3, it is connected to engine connecting shaft gear 5. By closing and opening clutch 6, pure electric drive of drive motor 3, series range extension, and parallel power output of engine 1 and drive motor 3 to front and rear wheels can be realized.

[0056] Its advantages are as follows: In this hybrid structure, the drive motor 3, engine 1, and generator 2 are arranged in parallel shafts, which shortens the axial space and makes the drive motor arrangement more flexible. It is suitable for models with requirements for axial space. The clutch 6 can be embedded in the rotor of generator 2, which further shortens the axial space. Its position is the original engine output CVT transmission space position, and the original engine output structure can be used. There is no need to modify the dual output of the engine crankshaft. The arrangement can be achieved with minimal changes to the whole vehicle and power system.
