Abstract
Description
Technical Field
[0001] The invention belongs to the field of output power distribution, and in particular relates to an active power distributor. Background Art
[0002] The power distributor covers a wide range of applications, such as power distribution between the two wings of a coaxial counter-rotating propeller helicopter, power distribution between wheels and shafts of a car, power distribution between the engine, electric (generator) machine, and wheel end (differential end) in a hybrid electric vehicle, power distribution between two tracks of tracked chassis vehicles such as tanks, power distribution between multiple power units of some ships, and other machinery that requires power distribution. At present, the power distribution mechanical devices used in mass production are mainly differentials and planetary gears. Among them, the power distributor (differential, differential lock, transfer case, etc.) used in vehicles is the most complex and changeable, with the highest requirements, and is related to the safety of people's lives and property. The advantages and disadvantages of its structural performance are particularly important. For example, an open differential is a common type of differential in a car's transmission system. Its original design intention is to allow the left and right wheels to rotate at different speeds, with a smooth differential, so as to adapt to the different speed requirements of the inner and outer wheels when the vehicle turns. However, the open differential also has some obvious disadvantages: power loss, insufficient traction, poor handling, and inability to cope with extreme road conditions, commonly known as: "slipping", "pushing head", "swinging", and "braking on one side".
[0003] In order to overcome these shortcomings, mechanical differential locks (such as Torsen differential lock, Eaton differential lock, tooth differential lock, etc.) and limited slip differential lock (LSD) or electronically controlled differential systems have appeared one after another. They can automatically adjust or limit the distribution of power when wheel slip is detected to improve traction and vehicle stability. Mechanical differential locks, limited slip differential locks (LSD), and electronically controlled differential systems have played a positive role in improving vehicle traction and vehicle stability, but they still have some shortcomings, including: delayed response, insensitivity, complex structure, poor stability, durability problems, lack of fine-tuning function, high driver skill requirements, and high cost. The structure and design logic of the controlled differential system is that when the wheel slips, the sensor senses the slip and then orders the actuator (clutch, friction method) to lock the differential to let the vehicle out of trouble. After the wheel slip is released, the sensor senses it and then orders the actuator to release the locked differential. Although this single differential locking and unlocking function can basically solve the driving conditions problems caused by differential structural and functional defects such as wheel "slipping", "pushing the head", "swinging", and "one-sided braking", this structure is difficult to improve the defects and shortcomings such as delayed response, insensitivity, complex structure, poor stability, poor durability, and no fine-tuning function. It often requires skilled operation by the driver and is often difficult for ordinary drivers to control. Therefore, there is room for further improvement in its safety structure.
[0004] At the same time, the power distribution between the engine, electric (generator) machine and wheel end in the traditional oil-electric hybrid system is mainly divided into series, parallel, hybrid and extended-range types. It mainly connects and coordinates the power conversion between the engine, electric motor, generator and wheel end through the clutch and transmission. It lacks stepless speed change capability and fine-tuning function, has a complex structure, many redundancies, and no obvious energy saving. In addition, traditional coaxial counter-rotating propeller helicopters all use a fixed power distribution structure, which is complex in design, cannot be fine-tuned, is heavy in weight, and has poor endurance. Summary of the invention

The input shaft passes through the casing and is fixedly connected with the center hole of the input gear. The meshing tooth surface of the input gear is respectively meshed with the left driven gear and the right driven gear, so that the left driven gear and the right driven gear rotate synchronously and at the same speed in opposite directions, so that the input power rotates through the left planetary gear set and the right planetary gear set (the worm gear does not rotate) to the output left half shaft and the output right half shaft, and the rotation is in the same direction and at the same speed; the center hole of the right half shaft gear is sleeved on the output right half shaft through a bearing or a bushing; the output left half shaft It passes through the casing and is fixedly connected with the center hole of the left half-shaft gear, and the output right half-shaft passes through the casing and is fixedly connected with the center hole of the double-sided half-shaft gear. The differential torque from the wheel end or the input power is transmitted between the left planetary gear set and the right planetary gear set through the double-sided half-shaft gear, and the small planetary gears and the worm gear rotate with each other to form a free differential. However, the worm gear is self-locked by the worm and cannot rotate freely. It can only rotate actively according to the differential demand under the active control of the computer, programmable motor and sensor, so that the vehicle can achieve the requirements of active and precise differential with direction and active and precise speed change with speed throughout the entire driving process.
[0007] One end of the worm is connected to the inner side of the casing through a bearing or a bushing, the meshing tooth surface of one end of the worm is meshed with the meshing tooth surface of the worm wheel, and a 3-20 times labor-saving lever ratio is formed, and the other end of the worm is connected to the rotor of the programmable motor; the signal line of the programmable motor is connected to the computer, and the signal line of the computer is connected to the sensor on the steering mechanism; the vehicle steering signal is transmitted to the computer through the sensor by the steering mechanism, and the computer starts the programmable motor according to the differential demand to drive the worm to accurately rotate the turbine, so as to achieve the purpose of synchronous precise differential, active precise differential steering, turning on the spot, and active precise differential speed change.
[0008] The worm wheel is designed as a circular ring bracket, and the right planetary gear set is 2-6 small planetary gears with the same meshing tooth parameters, which are evenly distributed in the inner cavity of the worm wheel through the gear shaft or directly in a ring shape.
[0009] The planet carrier is designed as a circular ring bracket, and the left planetary gear set is 2-6 small planetary gears with the same meshing tooth parameters, which are evenly distributed in the inner cavity of the planet carrier through gear shafts or directly in a ring shape.
[0010] The casing wraps the planet carrier, the left half-shaft gear, the left planetary gear set, the left driven gear, the double-sided half-shaft gear, the right planetary gear set, the worm wheel, the worm, the right driven gear, the right half-shaft gear, the input gear, the input shaft, the output left half-shaft, and the output right half-shaft pass through the casing through a dynamic seal, and the casing contains lubricating oil to lubricate the gears.
[0011] The two sides of the right planetary gear set are respectively meshed with the meshing tooth surfaces of the left half-shaft gear and the meshing tooth surfaces of the right half-shaft gear to balance the supporting worm gear; the output right half-shaft can also pass through the middle hole of the left half-shaft gear to fix the left half-shaft gear on the output right half-shaft, and the middle hole of the right half-shaft gear is sleeved on the output right half-shaft through a bearing or a bearing shell. The left end of the output right half-shaft is connected to the aircraft engine, and the right end of the output right half-shaft is connected to the upper blade of the helicopter.
[0012] A base for an annular load-bearing bearing or a bushing is provided in the middle of the double-sided half-shaft gear. The base can be designed as an annular base protruding from the edge of the meshing teeth of the double-sided half-shaft gear, or can be designed as an annular base recessed from the edge of the meshing teeth of the double-sided half-shaft gear. Meshing tooth surfaces are provided on both sides of the double-sided half-shaft gear and the parameters of the meshing tooth surfaces of the left half-shaft gear and the right half-shaft gear are the same.
[0013] The meshing tooth parameters of the left driven gear and the right driven gear are the same; The parameters of the planetary gears of the left planetary gear set and the right planetary gear set are the same.
[0014] The program-controlled motor can be designed on the outside of the casing or on the inside of the casing.
[0015] The operation mode of the active power distributor between axles, between wheels and hybrid of the present invention is: the power rotation is transmitted from the input shaft to the left driven gear and the right driven gear at the same time through the two sides of the input gear, so that the left driven gear and the right driven gear rotate synchronously, at the same speed and in opposite directions; the left driven gear transmits the left half-shaft gear and the double-sided half-shaft gear at the same time through the two sides of the small planetary gear on the left planetary gear set on the planetary carrier, the left half-shaft gear is linked to output the left half-shaft, and the double-sided half-shaft gear is linked to output the right half-shaft; the right driven gear transmits the double-sided half-shaft gear through the right half-shaft gear through the small planetary gear on the right planetary gear set in the worm gear, and the double-sided half-shaft gear is linked to output the right half-shaft.When the worm gear is not rotating, the left driven gear and the right driven gear are transmitted to the output left half shaft and the output right half shaft in the same direction and at the same speed, and the vehicle goes straight; when the worm gear rotates, the left driven gear and the right driven gear are transmitted to the output left half shaft and the output right half shaft in the same direction, and the equal speed rotation loses the equal speed, and the vehicle forms a differential turn; in the active precision differential, because the two sides of the input gear are respectively meshed with the left driven gear and the right driven gear, the left driven gear and the right driven gear rotate in opposite directions at the same speed synchronously, and the rotation is transmitted to the left and right wheels in opposite directions again through the left planetary gear set and the right planetary gear set, and the wheels (the worm gear is not rotating) rotate in the same direction and at the same speed, and the vehicle goes straight; the left and right wheel ends are due to When turning, "skidding", "pushing the head", "swinging the tail", "braking on one side" and other disordered differential torques force the small planetary gears on the planetary gear set to rotate through the left and right output half shafts and the left and right planetary gear sets. The small planetary gears link the worm gear to obtain free differential, but the worm gear is self-locked by the worm and cannot rotate freely. It can only rotate actively according to the differential demand under the active control of the computer, programmable motor and sensor, so that the vehicle can achieve active and precise differential with direction and active and precise speed change with speed throughout the entire driving process. In this process, the worm gear rotates passively, so there is no need to do work on the worm gear. You only need to rotate the worm itself to release the self-locking of the worm gear to achieve active and precise differential, so only hundreds of watts of power are needed. Active differential steering, when turning on the spot, requires a programmable motor, computer, and sensor. The worm gear actively works on the worm wheel to rotate the worm wheel, and the worm wheel actively drives the right planetary gear set to rotate. The right planetary gear set links the small planetary gear to drive the double-sided half-shaft gears and the left half-shaft gear to rotate in the opposite direction, thereby realizing active differential steering and turning on the spot. Since differential steering and turning on the spot require very low speeds, only kilowatts of power are required. When the active differential changes speed, a programmable motor, computer, and sensor are also required. The worm gear actively works on the worm wheel to rotate the worm wheel, and the worm wheel actively drives the right planetary gear set to rotate. The right planetary gear set links the small planetary gear to drive the double-sided half-shaft gears and the left half-shaft gear to rotate in the opposite direction. The worm gear rotates in the direction of the wheel to achieve active differential speed change. Due to the high engine speed, the worm gear speed should also be increased to match the engine speed, so the output power of the programmable motor needs to be increased synchronously. In order to reduce energy consumption and ensure that the engine always operates in a high-efficiency operating range, the programmable motor, computer, and sensor actively rotate the worm gear through the worm to achieve forward and reverse movement of the engine to transfer the power of the engine to the wheel end. The power transmitted to the power motor (generation) end can be actively switched at will, so that the vehicle starting, high speed, deceleration, and parking are all actively and autonomously controlled by the programmable motor-computer-sensor, allowing the vehicle to change speed steplessly without frustration and the engine does not need to slow down, and all excess power is transmitted to the power motor for power generation.
[0016] The connection and operation mode of the active power distributor and the hybrid element in the hybrid power usage scenario of the present invention is: the engine output power is input by the input shaft, the output right half shaft is connected to the power motor, and the output left half shaft is connected to the differential end; the output left half shaft can also be connected to the power motor, and the output right half shaft is connected to the differential end (wheel end); when driving purely electric, the engine does not work, the input shaft, the left driven gear and the right driven gear do not rotate, the output right half shaft and the output left half shaft are directly connected on both sides of the left planetary gear set through the left half shaft gear and the double-sided half shaft gear, and the power motor directly controls the vehicle like an ordinary electric car; when the engine is driving, the engine can always maintain an efficient operating range, and the computer-controlled programmable motor rotates the worm gear through the worm to adjust the speed. When waiting for speed, the computer-controlled programmable motor rotates synchronously with the input shaft through the worm gear, then the output left half shaft (differential end) does not rotate, the vehicle is stopped, and the engine output power All the force is input and output to the right half shaft (power motor end) for the power motor to generate electricity to the battery; the computer reduces the rotation speed of the worm gear, the vehicle starts to move, and the excess power is used to generate electricity for the power motor; the computer controls the worm gear to rotate synchronously with the input shaft in the opposite direction, and the engine output power is all input to the differential end (wheel end) to increase the vehicle speed; the power motor, engine, and programmable motor rotate at full speed at the same time, the torque and speed of the differential end (wheel end) double, and the vehicle can travel at ultra-high speed, that is, from the full power generation of the engine to the vehicle starting to ultra-high speed driving to deceleration to parking, the computer-programmable motor can control the positive and negative speed of the worm gear to achieve the purpose, which can be actively adjusted at will, the engine does not need to slow down, and the vehicle deceleration and braking torque can also be fully input to the power motor for power generation; when the engine and power motor are not working (not rotating), the computer-programmable motor rotates the worm gear in the forward and reverse directions, allowing the vehicle to move forward and backward at a low speed to achieve energy-saving driving.
[0017] On the basis of the above-mentioned active power distributor for vehicles, the present invention also extends to the active power distribution between the twin propellers of a coaxial counter-rotating propeller helicopter. Due to the use in the helicopter field and the special scenario, the left driven gear, the right driven gear, the input gear and the input shaft are subtracted from the above-mentioned structure; the flight elements in the input and output connection helicopter application scenario are: the output right half shaft is connected to the upper blade, the right half shaft gear is connected to the lower blade through a connecting sleeve, one end of the output left half shaft is connected to the aircraft engine, and the casing is fixedly connected to the fuselage beam. The operation mode of the present invention for the helicopter scenario is: during direct flight, the computer controls the rotation of the worm through a programmable motor, the worm is self-locking, the worm wheel does not rotate, and the aircraft engine-the output left half shaft rotates the double-sided half shaft gear through the left planetary gear set, and the hole in the double-sided gear rotates the upper blade through the fixedly connected output right half shaft The right half-shaft gear rotates in the opposite direction through the worm gear-right planetary gear set (the worm gear does not rotate) - the lower blade rotates at the same speed, and the inertia torque cancels each other out to form a balanced torque, so that the helicopter flies straight; when turning, the computer starts the program-controlled motor to drive the worm gear to rotate through the worm, and the planetary gear set rotates to break the opposite and uniform rotation of the lower blade and the upper blade, and the inertia torque balance is unbalanced and deflected, so the helicopter turns; when ascending, the computer starts the program-controlled motor to drive the worm gear to rotate in the opposite direction to the output right half-shaft through the worm, and the speed of the lower blade can be significantly higher than that of the upper blade, so the lift is significantly increased, which helps the helicopter to rise rapidly; when descending, the computer starts the program-controlled motor to drive the worm gear to rotate in the same direction as the output right half-shaft through the worm, and the speed of the lower blade can be significantly reduced, so the lift is significantly reduced, which helps the helicopter to descend smoothly.
[0018] Due to the special usage scenarios of helicopters, the actual needs of the helicopter structure are fully considered, and it is made as simple and compact as possible to reduce weight. The present invention can further remove the output left half shaft, planet carrier, left planetary gear set, double-sided half shaft gear on the basis of the above structure, retain the left half shaft gear, right planetary gear set, turbine, worm, right half shaft gear, programmable motor, computer, sensor, and output right half shaft; the helicopter elements in the input-output connection aircraft application scenario are: the right end of the output right half shaft (upward) is connected to the upper blade, the right half shaft gear is connected to the lower blade through a connector, the left end of the output right half shaft is connected to the aircraft engine, and the casing is fixedly connected to the fuselage beam. The operating mode and performance characteristics that can be achieved by further simplifying the structure of the present invention are: when flying straight, the computer controls the rotation of the worm through the programmable motor, the worm is self-locking, the worm wheel does not rotate, and the right planetary gear set drives the upper blade and the lower blade to rotate at the same speed in the opposite direction, offsetting the inertia torque and forming a balanced torque, and the helicopter; when turning, the computer starts the programmable motor to drive the worm wheel to rotate through the worm, and the right planetary gear set is linked to rotate. The opposite and uniform rotation of the lower blade and the upper blade is broken, the inertia torque balance is unbalanced, and deflection occurs, so the helicopter turns. When ascending, the computer starts the program-controlled motor to drive the worm wheel to rotate in the opposite direction of the transmission shaft through the worm. The speed of the lower blade can be significantly higher than that of the upper blade, so the lift is significantly improved, which helps the aircraft to ascend rapidly. When descending, the computer starts the program-controlled motor to drive the worm wheel to rotate in the same direction as the transmission shaft through the worm. The speed of the lower blade can be significantly reduced, so the lift is significantly reduced, which helps the helicopter to descend smoothly.
[0019] The present invention can also be used in mechanical parts such as ships and robots that require active power distribution.
[0020] The active power distributor proposed in the present invention realizes a structure of full gear meshing and symmetrical multi-point transmission torque through precise control of computer-sensor, which can synchronously and actively distribute power according to the differential needs, actively and accurately distribute power throughout the entire process, actively and accurately differential, actively turn the car, turn in place, and actively change the speed of the differential, which effectively solves many shortcomings of traditional differentials in different driving situations. The main features of the present invention include the following points: 1. Synchronous active precise differential: The present invention adopts the self-locking principle of the worm and worm gear, so that the worm gear cannot rotate at will (free differential). Under the active control of the computer, programmable motor and sensor, the worm gear can only rotate precisely according to the amount of differential calculated by the computer according to the direction of rotation, and the programmable motor is instructed to unlock the amount, thereby realizing precise adjustment of the differential torque, making the power distribution more active and flexible, and ensuring the vehicle body stability throughout the entire driving process.
[0021] 2. Active differential steering and turning on the spot: The present invention makes full use of the worm gear, double planetary gear set, double driven gear and double-sided gear combination. The two sides of the worm gear rotate synchronously while the worm gear is relatively stationary. The worm gear is actively controlled to achieve precise differential throughout the entire process. The worm gear is actively rotated to achieve active differential steering, turning on the spot and differential speed change. The safety, off-road performance and handling performance of the vehicle are further improved. The structure is simple, the structural redundancy of traditional vehicles is eliminated, the cost is significantly reduced and significant economic value is created.
[0022] 3. Active differential speed change: The computer, programmable motor, sensor, worm and worm gear of the present invention can actively distribute power of any ratio to achieve stepless adjustment of vehicle speed, charging of excess energy, speed reduction and braking energy recovery. The performance is comparable to the various modes of parallel, series and range extension of traditional oil-electric hybrid transmissions. The structure is compact and simple, and the complex hybrid transmissions, clutch and other redundant structures of traditional oil-electric hybrid vehicles can be abandoned, so that the vehicle running system is lighter, more durable and has lower energy consumption. The worm and worm gear of the present invention are one-way force transmission structures, which can effectively prevent the vehicle from slipping when starting.
[0023] 4. Full gear engagement: The present invention adopts full gear engagement and symmetrical multi-point torque transmission design, abandoning the traditional differential locking system based on clutch friction structure. It has higher transmission efficiency and reliability, while also being able to reduce noise and vibration, providing a more comfortable riding experience.
[0024] 5. Low-speed energy-saving driving: When the present invention is applied to hybrid vehicles, when the engine and the power motor are not working (not rotating), the computer-programmed motor rotates the worm gear forward and reverse, allowing the vehicle to move forward and backward at a low speed. This function is suitable for scenarios where the vehicle needs to creep, move forward and backward at a low speed, or reverse into a warehouse, and can significantly reduce the vehicle's energy consumption and reduce the cost of using the vehicle.
[0025] 6. Elastic connection between half-axles: Double-sided half-axle gears are made of high-strength elastic materials, such as high-strength nylon, so that the double-sided half-axle gears have the function of elastic couplings, which can prevent the worm gear from blocking the impact between teeth (tooth hitting) during passive differential; at the same time, it can also reduce the meshing accuracy requirements and prevent jamming.
[0026] Compared with the prior art, the present invention has the following technical effects: 1. Active and precise differential: Through the active control of the motor, the differential can be adjusted accurately in real time, allowing the vehicle to have precise differential throughout the entire driving process and meet driving needs under various complex road conditions. It solves traditional driving safety hazards such as vehicle tire "slipping", "pushing the head", "swinging", and "braking on one side" from the structural source.
[0027] 2. Active differential speed change: Compared with traditional mechanical structures such as differentials and differential locks, the active power distributor of the present invention adopts a more concise design, and has the multiple performances of traditional oil-electric hybrid transmissions in parallel, series, and range extension. At the same time, there is no redundancy of the complex transmission, clutch and other driving system structures of traditional vehicles, which reduces the volume and weight, and there is no sense of gear shifting frustration. The speed change is similar to that of a single-speed electric car. The speed and torque of the engine and motor can be superimposed, so that the vehicle speed can be doubled, and the space utilization and maneuverability of the vehicle are effectively improved. Since the worm and worm wheel are unidirectional outputs, the phenomenon of slipping at the start can be effectively prevented. The present invention can replace the traditional automobile hybrid transmission.
[0028] 3. Active differential steering: The present invention can actively and accurately perform differential turns and turn on the spot. It has a full gear meshing structure, which is accurate, safe and reliable. It can replace the complex traditional steering system. Only a steering calculation system needs to be added, which can save a lot of space and weight of the vehicle, make the turning range wider and the accuracy higher. It is better than the tank steering system and can replace the traditional steering system.
[0029] 4. Turning on the spot: In the turning on the spot mode, only the movement of the worm and worm wheel is controlled by the programmable motor to realize the reverse drive of the wheels on both sides, so as to achieve the purpose of turning the vehicle on the spot, greatly improving the maneuverability of the vehicle.
[0030] 5. Improve reliability (full gear meshing): Due to the use of full gear meshing transmission and active computer control, the present invention has higher reliability and durability and can adapt to long-term use in various harsh environments.
[0031] 6. Low-speed energy-saving driving: When the program-controlled motor (5-10 kilowatt power) of the present invention is working, the vehicle can be driven at a low speed, reverse into a garage, turn around on the spot, thereby reducing the low-speed energy consumption of the vehicle.
[0032] 7. Reduce energy consumption: By optimizing the power distribution plan, reducing structural redundancy, lowering the body, and reducing the vehicle's driving resistance, fuel consumption can be saved.
[0033] 8. Intelligent control: By integrating advanced sensors and control systems, the active power distributor of the present invention can achieve intelligent control and management, improving driving comfort and convenience.
[0034] 9. Strong durability: The double-sided half-axle gear of the present invention is made of high-strength elastic material, such as high-strength nylon, so that the double-sided half-axle gear has the function of an elastic coupling, which can prevent the worm gear from blocking the impact between teeth (tooth hitting) during passive differential; at the same time, it can also reduce the meshing accuracy requirements, prevent jamming, reduce vibration, effectively increase the service life, and improve safety and comfort.
[0035] 10. Improve driving pleasure: Through precise power distribution and flexible handling performance, the active power distributor of the present invention can bring the driver a more pleasant and exciting driving experience.
[0036] 11. Energy saving and environmental protection: By reducing energy consumption and reducing the potential for pollutant emissions, the active power distributor of the present invention helps promote the green development and sustainable development of the automotive industry.
[0037] 12. Create economic benefits: By reducing production costs, improving product quality and expanding market share, the active power distributor of the present invention is expected to create significant economic benefits and social value for the enterprise.
[0038] To sum up, the present invention is an active power distributor with full gear meshing and symmetrical multi-point transmission torque, which can synchronously and actively distribute power accurately according to differential needs, fully actively and accurately differentiate, actively and accurately differential, actively and differentially steer, turn on the spot, and actively and differentially change speed. The present invention realizes active, synchronous and accurate distribution of power through innovative design concepts and advanced technical means, and can replace traditional transmissions, clutches, differentials, differential locks, steering systems and other structures, thereby improving the vehicle's driving stability, traction and controllability, and durability, and significantly reducing energy consumption and maintenance costs.

The right outer side of the right half-shaft gear 1-12 is fixedly connected to the right driven gear 1-10, and the meshing tooth surface faces the left side, which is opposite to the meshing tooth surface of the left driven gear 1-5. The input shaft 1-17 passes through the housing 1-15 and is fixedly connected to the center hole of the input gear 1-16. The meshing tooth surfaces of the input gear 1-16 are respectively meshed with the left driven gear 1-5 and the right driven gear 1-10, and the transmission left driven gear 1 —5. The right driven gear 1-10 rotates synchronously and at the same speed in the opposite direction, so that the input power rotates through the left planetary gear set 1-4 and the right planetary gear set 1-7 (the worm gear 1-8 does not rotate) to the output left half shaft 1-1 and the output right half shaft 1-11, and the rotation is in the same direction and at the same speed.

However, the worm gear 1-8 is self-locked by the worm 1-9 and cannot rotate freely. It can only rotate actively according to the differential demand under the active control of the computer 1-14, the programmable motor 1-13, and the sensor 1-18, so that the vehicle can achieve the requirements of active and precise differential with direction and active and precise speed change with speed throughout the entire driving process.
[0041] The casing 1-15 wraps the planetary carrier 1-2, the left half-shaft gear 1-3, the left planetary gear set 1-4, the left driven gear 1-5, the double-sided half-shaft gear 1-6, the right planetary gear set 1-7, the worm gear 1-8, the worm 1-9, the right driven gear 1-10, the right half-shaft gear 1-12, and the input gear 1-16; the input shaft 1-17, the output left half-shaft 1-1, and the output right half-shaft 1-11 pass through the casing 1-15 through the dynamic seal, and the casing 1-15 contains lubricating oil to lubricate the gears.

The other end of the worm 1-9 is connected to the rotor of the programmable motor 1-13, and the signal line of the programmable motor 1-13 is connected to the computer 1-14. The signal line of the computer 1-14 is connected to the sensor 1-18 on the steering mechanism. The vehicle steering signal is transmitted to the computer 1-14 through the sensor 1-18 by the steering mechanism. The computer 1-14 starts the programmable motor 1-13 according to the differential demand to drive the worm 1-9 to accurately rotate the worm wheel 1-8, so as to achieve the purpose of synchronous precise differential, active precise differential steering, turning in place, and active precise differential speed change.
[0043] The worm gears 1-8 are designed as annular brackets, and the right planetary gear set is 2-6 small planetary gears with the same meshing tooth parameters, which are evenly distributed in the inner cavity of the worm gears 1-8 through gear shafts or directly in annular shapes.
[0044] The planet carrier 1-2 is designed as a circular ring bracket, and the left planetary gear set 1-4 is 2-6 small planetary gears with the same meshing tooth parameters, which are evenly distributed in the inner cavity of the planet carrier 1-2 through the gear shaft or directly in the form of a ring.
[0045] The double-sided half-shaft gear 1-6 is provided with a base for an annular load-bearing bearing or a bushing in the middle. The base can be designed as an annular base protruding from the edge of the meshing teeth, or can be designed as an annular base recessed from the edge of the meshing teeth of the double-sided half-shaft gear. Meshing tooth surfaces are provided on both sides of the double-sided half-shaft gear 1-6 and the meshing tooth surface parameters are the same as those of the left half-shaft gear 1-3 and the right half-shaft gear 1-11.
[0046] The meshing tooth parameters of the left driven gear 1-5 and the right driven gear 1-10 are the same.
[0047] The parameters of the planetary gears of the left planetary gear set 1-4 and the right planetary gear set 1-7 are the same.
[0048] The program-controlled motors 1-13 are designed inside the casing.
[0049] The operation mode and performance characteristics that can be achieved in the first embodiment of the present invention are as follows: the present embodiment is mainly used for active power distribution between vehicle axles and wheels. The power rotation is transmitted from the input shaft 1-17 through both sides of the input gear 1-16 to the left driven gear 1-5 and the right driven gear 1-10, so that the left driven gear 1-5 and the right driven gear 1-10 rotate synchronously, at the same speed, and in opposite directions; the left driven gear 1-5 simultaneously transmits the left half-shaft gear 1-3 and the double-sided half-shaft gear 1-6 through both sides of the small planetary gear on the left planetary gear set 1-4 on the planetary carrier 1-2, and the left half-shaft gear 1-3 is linked to output the left half-shaft 1-1, and the double-sided half-shaft gear 1-6 is linked to output the right half-shaft 1-11; the right driven gear 1-10 transmits the double-sided half-shaft gear 1-6 through the right half-shaft gear 1-12 through the small planetary gear on the right planetary gear set 1-7 in the worm gear 1-8, and the double-sided half-shaft gear 1-6 is linked to output the right half-shaft 1-11. When the worm gear 1-8 does not rotate, The left driven gear 1-5 and the right driven gear 1-10 are transmitted to the output left half shaft 1-1 and the output right half shaft 1-11 in the same direction and at the same speed, and the vehicle goes straight; when the worm gear 1-8 rotates, the left driven gear 1-5 and the right driven gear 1-10 are transmitted to the output left half shaft 1-1 and the output right half shaft 1-11 in the same direction and at the same speed, and the uniform speed is lost, and the vehicle forms a differential turn; the movement mode during active precision differential, active differential turn, in-situ turn, and active differential shifting : In active precision differential, because the input gear 1-16 is meshed with the left driven gear 1-5 and the right driven gear 1-10 on both sides, the left driven gear 1-5 and the right driven gear 1-10 rotate synchronously in opposite directions at the same speed, and the rotation is transmitted to the left and right wheels in the opposite direction again through the left planetary gear set 1-4 and the right planetary gear set 1-7 (the worm gear 1-8 does not rotate). The wheels then rotate in the same direction and at the same speed, and the vehicle goes straight; the left and right wheel ends "slip" due to turning, The disordered differential torques such as "pushing head", "swinging tail" and "braking one-sidedly" force the small planetary gears on the planetary gear set to rotate through the left and right output half shafts and the left and right planetary gear sets. The small planetary gears link the worm gears 1-8 to obtain free differential, but the worm gears 1-8 are self-locked by the worm 1-9 and cannot rotate freely. They can only rotate actively according to the differential demand under the active control of the computer 1-14, the programmable motor 1-13 and the sensor 1-18, so that the vehicle can achieve the requirements of active and precise differential with direction and active and precise speed change with speed throughout the driving process. In this process, the worm gears 1-8 rotate passively, so there is no need to The worm gear 1-8 works, and only the worm 1-9 is rotated to release the self-locking of the worm gear 1-8, so that active and precise differential can be achieved, so only a hundred watts of power is needed; in active differential steering and turning on the spot, the computer 1-14, the programmable motor 1-13, and the sensor 1-18 are required to actively work on the worm gear 1-8 through the worm 1-9 to rotate the worm gear 1-8, and the worm gear 1-8 actively drives the right planetary gear set 1-7 to rotate, and the right planetary gear set 1-7 links the small planetary gear to drive the double-sided half-shaft gear 1-6 and the left half-shaft gear 1-5 to rotate in the opposite direction, so as to realize active differential steering and turning on the spot;Because the speed required for differential steering and turning in place is very low, only kilowatts of power are needed; when the active differential speed is changed, the computer 1-14, the programmable motor 1-13, and the sensor 1-18 are also needed. The worm 1-9 actively works on the worm wheel 1-8 to rotate the worm wheel 1-8, and the worm wheel 1-8 actively drives the right planetary gear set 1-7 to rotate. The right planetary gear set 1-7 links the small planetary gear to drive the double-sided half-shaft gear 1-6 and the left half-shaft gear 1-5 to rotate in the opposite direction to realize the active differential speed change. Because the engine speed is high, the speed of the worm wheel 1-8 should also be increased to match the engine speed, so the output power of the programmable motor 1-13 needs to be increased synchronously. ;

[0072] One end of the worm 1-9 is connected to the inner side of the casing 1-15 through a bearing or a bushing, the meshing tooth surface of the worm 1-9 meshes with the meshing tooth surface of the worm wheel 1-8, and forms a 3-20 times labor-saving lever ratio, and the other end of the worm 1-9 is connected to the rotor of the programmable motor 1-13; the signal line of the programmable motor 1-13 is connected to the computer 1-14, and the signal line of the computer 1-14 is connected to the sensor 1-18 on the steering mechanism; the steering signal of the helicopter is transmitted to the computer 1-14 through the sensor 1-18 by the steering mechanism, and the computer 1-14 starts the programmable motor 1-13 according to the differential demand to drive the worm to accurately rotate the worm wheel 1-8, so as to achieve the purpose of actively adjusting the rotation speed of the lower blade 2-2 and the upper blade 2-3.
[0073] The casing 1-15 is fixedly connected to the fuselage beam, and encloses: the left half-shaft gear 1-3, the right planetary gear set 1-7, the worm gear 1-8, the right half-shaft gear 1-12, and the programmable motor 1-13. Both ends of the output right half-shaft 1-11 pass through the casing 1-15 through dynamic seals, and the casing 1-15 contains lubricating oil to lubricate the gears.
[0074] The worm gears 1-8 are designed as annular brackets, and the right planetary gear set is 2-6 small planetary gears with the same meshing tooth parameters, which are evenly distributed in the inner cavity of the worm gears 1-8 through gear shafts or directly in annular shapes.

[0077] The operation mode and performance characteristics that can be achieved by the fourth embodiment of the present invention are as follows: This embodiment is mainly used for helicopters. Due to the special use scenarios of helicopters, the actual needs of the helicopter structure are fully considered, and the structure is as simple and compact as possible to reduce weight. This embodiment further simplifies the structure on the basis of the structure of the third embodiment. When flying straight, the computer 1-14 prevents the worm 1-9 from rotating through the program-controlled motor 1-13, the worm 1-9 is self-locking, the worm wheel 1-8 does not rotate, and the right planetary gear set 1-7 drives the connecting sleeve 2-1 and the right half shaft 1-11 to rotate at the same speed and in the opposite direction; then the upper blade 2-3 and the lower blade 2-2 also rotate at the same speed in the opposite direction, offsetting the inertia torque, forming a balancing torque, and the helicopter flies straight. When turning, the computer 1-14 starts the program-controlled motor 1-13 to drive the worm wheel 1-8 to rotate through the worm 1-9, and the right planetary gear set 1-7 rotates. The opposite and uniform rotation of the lower blade 2-2 and the upper blade 2-3 is broken, the inertia torque balance is unbalanced, deflection occurs, and the helicopter turns. When ascending, the computer 1-14 starts the program-controlled motor 1-13 to drive the worm wheel 1-8 to rotate in the opposite direction of the transmission shaft through the worm 1-9. The speed of the lower blade 2-2 can be significantly higher than that of the upper blade 2-3, so the lift is significantly improved, which helps the coaxial twin-propeller aircraft to rise rapidly. When descending, the computer 1-14 starts the program-controlled motor 1-13 to drive the worm wheel 1-8 to rotate in the same direction as the transmission shaft through the worm 1-9, and the speed of the lower blade 2-2 can be significantly reduced, so the lift is significantly reduced, which helps the helicopter to descend smoothly.
