Description

Technical Field

[0001] This invention relates to the field of mechanical transmission and electrical energy conversion technology, specifically to an integrated drive device combining coaxial electromagnetic coupling stepless reduction and stator anti-torque power generation. Background Technology

[0002] Existing transmission systems generally suffer from problems such as complex structure, limited speed range, insufficient torque amplification capability, inability to recover energy, low transmission efficiency, high wear, and high maintenance costs. Traditional reducers, gearboxes, hydraulic torque converters, and single-stage reduction electric drive axles cannot simultaneously achieve stepless speed regulation, high torque amplification, real-time power generation, and bidirectional independent control, making it difficult to meet the requirements of next-generation high-efficiency, energy-saving, and high-power-density transmission systems. Summary of the Invention

[0003] The present invention aims to overcome the above-mentioned defects and provide a coaxial electromagnetic coupling continuously variable torque amplification drive power generation device. The device uses a coaxial electromagnetic coupler as the core component and adopts a single central main shaft coaxial through structure to realize the integration of continuously variable speed, torque amplification, power output and induction power generation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A coaxial electromagnetic coupling continuously variable speed torque amplification drive power generation device includes a central main shaft, a power input mechanism, a coaxial electromagnetic coupler, and a power output mechanism. The device has a coaxial layout and adopts a front-to-back axially split structure. The power input mechanism and the coaxial electromagnetic coupler are rigidly connected coaxially through the central main shaft. The coaxial electromagnetic coupler is rotatably housed within a housing and includes a rotor and an output stator. The rotor employs a magnetic structure, and the output stator uses coil windings. The power input mechanism drives the rotor within the coaxial electromagnetic coupler to rotate. The rotating rotor's magnetic field cuts the output stator coils, generating an induced electromotive force in the output stator, thus achieving inductive power generation. Simultaneously, an Ampere force is generated on the output stator, resisting the relative rotation of the rotor and the output stator. This Ampere force drives the output stator to rotate in the same direction as the rotor, transmitting this rotation to the power output mechanism. In the power transmission path, the speed decreases progressively and the torque is amplified synchronously, achieving the synergistic goal of efficient power generation and high-torque low-speed output.

[0006] The rotor and the power input mechanism are fixedly connected and rotate synchronously through the central main shaft. Automatic torque amplification and induction power generation are achieved through the speed difference between the rotor and the output stator. Stepless speed regulation of the output stator is achieved by adjusting the external load of the rotor or the speed of the power input mechanism.

[0007] By adopting the above technical solution, the power input mechanism is specifically set as a drive motor. The output end of the drive motor is coaxially and fixedly connected to the central main shaft. The rotor is coaxially and fixedly sleeved on the central main shaft. The drive motor drives the rotor to rotate through the central main shaft, providing rotational power input to the rotor. The speed of the drive motor can be independently adjusted, providing a basic power source for the entire system.

[0008] The coaxial electromagnetic coupler is coaxially set with the central main shaft. The rotor and output stator are coaxially set from the inside out. Both the rotor and output stator are rotatably housed inside the housing. The central main shaft transmits the rotational angular velocity of the drive motor output end to the rotor, causing the rotor to rotate. The rotor magnetic field rotates and cuts the coil windings of the output stator, thereby generating an induced electromotive force on the output stator and generating an induced current on the output stator, so as to achieve the technical effect of generating electricity and recovering electrical energy.

[0009] At the same time, the output stator rotates within the magnetic field environment formed by the rotor, cutting magnetic field lines. This generates an Ampere force that opposes the rotation of the output stator relative to the rotor. This Ampere force drives the output stator and rotor to rotate in the same direction. In the power transmission path, the speed decreases step by step and the torque is amplified synchronously, achieving the synergistic goal of efficient power generation and high torque low speed output. Meanwhile, the reaction force of this Ampere force acts on the rotor, causing the speed of the drive motor output end, the central main shaft and the rotor to decrease.

[0010] During the above process, the rotor speed gradually decreases while the output stator speed gradually increases. The induced electromotive force and output current on the output stator decrease along with the speed difference. The magnitudes of the rotor deceleration and the output stator acceleration gradually decrease until the rotational difference between the rotor and the output stator forms an Ampere force that can just drive the output stator to rotate at a certain fixed speed. At this point, the speeds of the rotor and the output stator no longer change. The rotor and the output stator rotate at stable speeds, smoothly realizing the power generation of the rotor and the power output of the output stator.

[0011] Correspondingly, by adjusting the speed of the drive motor output terminal to adjust the output current of the stator, the Ampere force acting on the output stator and the reaction force of the Ampere force acting on the rotor increase or decrease accordingly, thereby achieving stepless control of the output stator speed. Increasing the output current will correspondingly increase the output stator speed, realizing continuous stepless change of the output shaft speed from 0 to the maximum input speed.

[0012] When the load connected to the output stator increases, the current on the output stator decreases, the Ampere force acting on the output stator decreases, the rotor speed increases, the speed difference increases, the Ampere force increases, and then the speed of the output stator increases, eventually reaching a new equilibrium, the induced electromotive force increases, the power generation increases, the output stator speed increases, and the power output increases.

[0013] This invention can control the amount of electricity generated and the output power by adjusting the speed of the drive motor and the size of the power generation load.

[0014] The output stator adopts a rotary structure. The electrical energy generated by the rotating output stator is led out without contact through a coaxial magnetic ring / conductive ring, avoiding the problems of wear, arcing and poor contact of traditional slip rings. The magnetic ring power supply unit realizes stable power transmission between the rotating and fixed parts, ensuring reliability under high speed, heavy load and long-term operation.

[0015] The invention is further configured to include a hybrid power connection mechanism, which is located at the front end of the power input mechanism and is connected to the power input mechanism through a one-way overrunning clutch to realize the switching between pure electric and hybrid modes; in pure electric mode, the central main shaft is separated and the engine does not rotate.

[0016] By adopting the above technical solution, the engine is connected to the drive motor via a one-way overrunning clutch. Engine power is transmitted unidirectionally to the power coupling mechanism via the one-way overrunning clutch, engaging only when the engine is driving. When the system switches to pure electric drive or deceleration mode, the clutch automatically disengages, decoupling the engine from the power output, avoiding back drag losses, while ensuring the smoothness and efficiency of independent motor drive. This structure achieves flexible coupling and shock-free switching of engine and motor power, providing stable and efficient power distribution and transmission assurance for the vehicle's hybrid system.

[0017] The present invention is further configured such that the recovered electrical energy generated by the output stator can be exported non-contactly through electromagnetic induction or through carbon brush slip rings, which can be freely selected by the production process.

[0018] By adopting the above technical solutions, the recovered electrical energy generated by the output stator during actual use can be extracted without contact through electromagnetic induction or through carbon brush slip rings, which can be freely selected by the production process and does not depend on a single technology.

[0019] For products that prioritize long lifespan and high reliability, contactless systems can be chosen, avoiding the hidden costs of frequent downtime maintenance. For cost-sensitive consumer products, carbon brush slip rings are a mature and low-cost option, and even if they need to be replaced regularly, the overall lifecycle cost may be lower. Even if there is a shortage of a certain slip ring material or a bottleneck in a certain wireless power transmission technology, solutions can be quickly switched to ensure that production is not affected.

[0020] The present invention is further configured such that: the power input mechanism adopts a universal power interface that can be adapted to various types of drive motors.

[0021] By adopting the above technical solution, it is not necessary to redesign a set of housings and connection structures for each type of motor. Different models of motors can be matched according to actual needs. When only the motor part needs to be replaced, only the corresponding part needs to be replaced. There is no need to replace the entire set of equipment, which is highly adaptable.

[0022] The invention is further configured such that: the rotor outputs rotational power through a flange, and the flange is coaxially mounted on the central main shaft.

[0023] By adopting the above technical solution, the flange is mounted on the central spindle through bearings, and the output stator and the central spindle are mechanically decoupled. The output stator can rotate at completely different speeds, which is the premise for realizing the speed difference between the rotor and the output stator and the stepless speed change of the output stator.

[0024] The present invention is further configured such that: the coaxial electromagnetic coupling continuously variable torque amplification drive power generation device adopts a closed shell and an interlayer air gap heat dissipation structure.

[0025] By adopting the above technical solution, the heat dissipation efficiency can be improved. The interlayer air gaps act as built-in air ducts, allowing cooling air to flow directly through the areas with the most severe heat generation, achieving real-time cooling and heat dissipation, rather than passively dissipating heat after it is transferred to the outer shell. Each layer of the cylinder wall is a heat dissipation surface. Through the annular gaps between the multiple layers, the cooling medium can simultaneously contact both the inner and outer cylinder walls, resulting in a heat exchange area per unit volume that is much larger than that of a solid structure, thus improving heat dissipation efficiency. Furthermore, the airflow within the annular gaps can evenly remove heat in the circumferential direction, avoiding localized hot spots caused by uneven cooling in traditional motors, thereby protecting the insulation materials and extending the winding life.

[0026] The beneficial effects of this invention are:

[0027] 1. Centered on a coaxial electromagnetic coupler, this device truly achieves gearless, stepless speed regulation, torque amplification, and power generation integration: The core of this device is a multi-layered coaxial nested electromagnetic coupling structure. Utilizing the speed difference between the inner and outer rotors, torque is directly transmitted via electromagnetic fields, replacing traditional mechanical gears and thus eliminating the need for tooth surface wear and lubrication. By continuously adjusting the electromagnetic coupling strength of the inner and outer rotors (changing the excitation current), stepless and smooth changes in the transmission ratio can be achieved. This allows for torque amplification at low speeds for heavy-load starts and maintains high efficiency at high speeds. Simultaneously, during power output, the outer rotor naturally induces electrical energy due to changes in the magnetic field, achieving integrated drive and power generation without the need for an additional generator.

[0028] 2. Supports both pure electric and hybrid modes, connecting to the engine via a one-way clutch to adapt to power needs in all scenarios: The front end of the central spindle is connected to the engine via a one-way overrunning clutch; in pure electric mode, the motor drives the spindle to rotate, at which time the spindle speed is higher than the engine speed, the one-way clutch automatically disengages, and the engine is completely stationary to avoid additional losses; when the engine needs to intervene, the engine speed exceeds the spindle speed, the one-way clutch immediately engages, and hybrid electric drive is achieved.

[0029] 3. Energy recovery can be achieved through either electromagnetic induction or carbon brush slip ring extraction, offering flexible manufacturing options and no limitations on the process. The recovered energy generated by the stator can be extracted in two ways: electromagnetic induction extraction utilizes an induction coil fixed to the housing to obtain energy without contact via electromagnetic coupling, requiring no maintenance and suitable for high-speed, enclosed, and explosion-proof scenarios; carbon brush slip ring extraction uses traditional contact conductivity, which is simple in structure, low in cost, and has high transmission efficiency, suitable for high-current conditions where maintenance cycles are not critical. In actual use, the choice can be made freely based on product positioning, cost budget, and target market without altering the main design, greatly improving production flexibility.

[0030] 4. No mechanical gears, no friction loss, maintenance-free, long lifespan, low noise, and extremely high reliability: Because power transmission relies entirely on electromagnetic fields, there are no gear meshing or friction parts, thus eliminating mechanical wear and lubricant deterioration issues. This not only achieves lifetime maintenance-free operation but also fundamentally eliminates gear meshing noise and vibration, resulting in extremely quiet operation. The electromagnetic coupler itself is non-contact, with no fatigue life limit, and the overall reliability is far higher than traditional gearboxes, making it particularly suitable for military, aerospace, and unmanned equipment with high reliability requirements.

[0031] 5. The central spindle output has a compact structure, high coaxiality, and smooth operation: The rotor is folded to the central spindle through the end flange, but the flange and the spindle are supported by bearings to achieve coaxial but different speeds. This design allows the outermost large torque power to be concentrated at the central output, and all rotating parts share the same spindle as the reference, ensuring extremely high coaxiality and smooth operation.

[0032] 6. The well-designed heat dissipation duct provides strong heavy-duty capacity: The annular gap between the multi-layered sleeves naturally forms a cooling duct, and the end flanges can be made into a fan shape, automatically generating airflow with rotation, forcibly convection to remove heat. This self-ventilated cooling structure eliminates the need for external fans or water pumps, yet efficiently cools the innermost heat-generating winding. Excellent heat dissipation performance ensures that the magnetic flux density does not decrease and the insulation does not age under prolonged heavy-duty conditions, thus enabling it to withstand extreme load scenarios such as mining machinery, tank armor, and heavy trucks.

[0033] 7. Universal power input, compatible with various motors and engines, highly versatile and widely applicable: The device's input interface is designed with a standard flange or shaft extension, allowing direct connection to the vast majority of drive motors and internal combustion engines on the market. This universal interface makes the device an independent "power enhancement and transmission module," allowing users to achieve different performance combinations simply by changing the front-end power source. Whether it's pure electric passenger vehicles, hybrid trucks, or industrial transmission systems, it can be used plug-and-play, greatly expanding its application areas and reducing system integration difficulty.

[0038] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] This device is installed between the power source and the load. When the drive motor is energized, it rotates, and the electromagnetic coupler transmits power, with the reverse torque driving the power generation unit. The controller achieves primary speed regulation by adjusting the drive motor speed and secondary stepless speed regulation by adjusting the power generation load. The lower the rotor speed, the higher the torque amplification factor. The electrical energy generated by the rotating stator is extracted without contact through a coaxial magnetic ring, and can be stored, fed back, or used directly. The entire device achieves stepless speed change, stepless torque amplification, real-time power generation, bidirectional independent control, and contactless power extraction in one integrated operation.

[0040] The specific structure of the present invention:

[0041] A coaxial electromagnetic coupling continuously variable torque amplification drive power generation device includes a central main shaft 1, a power input mechanism 2, a coaxial electromagnetic coupler, and a power output mechanism. The device has a coaxial layout and adopts a front-to-back axially split structure. The power input mechanism 2 and the coaxial electromagnetic coupler are rigidly connected coaxially through the central main shaft 1. The coaxial electromagnetic coupler is rotatably housed within a housing 3. The coaxial electromagnetic coupler includes a rotor 4 and an output stator 5. The rotor 4 employs a magnetic structure, and the output stator 5 uses coil windings. The power input mechanism 2 drives the rotor 4 within the coaxial electromagnetic coupler to rotate. The rotating rotor 4's magnetic field cuts the coils of the output stator 5, generating an induced electromotive force, thus achieving inductive power generation. Simultaneously, an Ampere force is generated on the output stator 5, resisting the relative rotation of the rotor 4 and the output stator 5. This Ampere force drives the output stator 5 and rotor 4 to rotate in the same direction. The output stator 5 transmits this rotation to the power output mechanism. In the power transmission path, the speed decreases progressively and the torque is amplified synchronously, achieving the synergistic goal of efficient power generation and high-torque low-speed output.

[0042] Furthermore, it also includes a hybrid power connection mechanism, which is located at the front end of the power input mechanism 2 and is connected to the central main shaft 1 through a one-way overrunning clutch 7 to realize the switching between pure electric and hybrid modes; in pure electric mode, the one-way clutch is disengaged and the engine 6 does not rotate.

[0043] Furthermore, the rotor 4 and the power input mechanism 2 are fixedly connected and rotate synchronously through the central main shaft 1. Automatic torque amplification and induction power generation are achieved through the speed difference between the rotor 4 and the output stator 5. Stepless speed regulation of the output stator 5 is achieved by adjusting the magnitude of the power generation current of the rotor 4 or the speed of the power input mechanism 2.

[0044] Furthermore, the recovered electrical energy generated by the output stator 5 can be extracted non-contactly through electromagnetic induction or through the carbon brush slip ring 8, which can be freely selected by the production process.

[0045] Furthermore, the power input mechanism 2 adopts a universal power interface that can be adapted to various types of drive motors, eliminating the need to redesign a housing 3 and connection structure for each type of motor. Different models of motors can be matched according to actual needs.

[0046] Furthermore, the rotor 4 outputs rotational power through the flange 9, which is coaxially mounted on the central spindle 1. The flange 9 is mounted on the central spindle 1 through bearings. The output stator 5 is mechanically decoupled from the central spindle 1, and the output stator 5 can rotate at completely different speeds.

[0047] Furthermore, the coaxial electromagnetic coupling continuously variable torque amplification drive power generation device adopts a closed shell 3 and an interlayer air gap heat dissipation structure. The interlayer air gap serves as an internal air duct, allowing cooling air to flow directly through these areas with the most severe heat generation, achieving real-time cooling and heat dissipation, rather than waiting for the heat to be transferred to the shell 3 and then passively dissipated.

[0048] The working process of this invention:

[0049] The output end of the drive motor is coaxially and fixedly connected to the central spindle 1. The rotor 4 is coaxially and fixedly sleeved on the central spindle 1. The drive motor drives the rotor 4 to rotate through the central spindle 1, providing rotational power input to the rotor 4. The speed of the drive motor can be independently adjusted, providing a basic power source for the entire system.

[0050] The coaxial electromagnetic coupler is coaxially arranged with the central main shaft 1. The rotor 4 and the output stator 5 are coaxially arranged from the inside to the outside. Both the rotor 4 and the output stator 5 are rotatably housed inside the outer casing 3. The central main shaft 1 transmits the rotational angular velocity of the output end of the drive motor to the rotor 4, causing the rotor 4 to rotate. The magnetic field of the rotor 4 rotates and cuts the coil winding of the output stator 5, thereby generating an induced electromotive force on the output stator 5 and generating an induced current on the output stator 5, so as to achieve the technical effect of generating electricity and realizing the recovery of electrical energy.

[0051] At the same time, the output stator 5, which is driven by the current, rotates within the magnetic field environment formed by the rotor 4, cutting magnetic field lines. This generates an Ampere force that opposes the rotation of the output stator 5 relative to the rotor 4. This Ampere force drives the output stator 5 to rotate in the same direction as the rotor 4. In the power transmission path, the speed decreases step by step and the torque is amplified synchronously, achieving the synergistic goal of efficient power generation and high torque low speed output. Meanwhile, the reaction force of this Ampere force acts on the rotor 4, causing the speed of the drive motor output end, the central main shaft 1, and the rotor 4 to decrease.

[0052] During the above process, the rotational speed of rotor 4 gradually decreases while the rotational speed of output stator 5 gradually increases. The induced electromotive force and output current on output stator 5 decrease along with the speed difference. The deceleration of rotor 4 and the acceleration of output stator 5 gradually decrease until the reaction force of the rotational difference between rotor 4 and output stator 5 is just enough to drive output stator 5 to rotate at a certain fixed speed. At this point, the speed of rotor 4 and output stator 5 no longer changes. At this time, rotor 4 and output stator 5 rotate at a stable speed, smoothly realizing the power generation of rotor 4 and the power output of output stator 5.

[0053] Correspondingly, when the current of the output stator 5 is adjusted by adjusting the speed of the drive motor rotor 4, the Ampere force acting on the output stator 5 and the reaction force of the Ampere force acting on the rotor 4 increase or decrease accordingly, thereby realizing stepless control of the speed of the output stator 5. Increasing the output current will correspondingly increase the speed of the output stator 5, realizing continuous stepless change of the output shaft speed from 0 to the maximum input speed.

[0054] When the load connected to the output stator 5 increases, the current on the output stator 5 decreases, the Ampere force acting on the output stator 5 decreases, the speed of the rotor 4 increases, the speed difference increases, and then the Ampere force and the reaction force of the Ampere force increase. Subsequently, the speed of the output stator 5 increases, and finally a new equilibrium is reached. The induced electromotive force increases, the power generation increases, the speed of the output stator 5 increases, and the power output increases.

[0055] The output stator 5 adopts a rotary structure. The electrical energy generated by the rotating output stator is led out without contact through a coaxial magnetic ring / conductive ring, avoiding the problems of wear, arcing and poor contact of traditional slip rings. The magnetic ring power supply unit realizes stable power transmission between the rotating part and the fixed part, ensuring high-speed, heavy-load and long-term working reliability.

[0056] This invention can control the amount of electricity generated and the output power by adjusting the speed of the drive motor and the size of the power generation load.

[0057] The driving of rotor 4 in the above process can be achieved by pure electric drive mode and hybrid drive mode:

[0058] Pure electric drive mode: The power input device drives the central spindle 1 to rotate, and the inner rotor 4 of the coaxial electromagnetic coupler rotates synchronously; the inner rotor 4 and the outer coupling component form a magnetic field speed difference, realizing stepless speed change, torque amplification, and generating induced electric energy; the electric energy is recovered through induction or carbon brush slip ring 8, and the external power supply only supplements the system loss.

[0059] Hybrid drive mode: Engine 6 is connected to the power input end through a one-way valve and drives in coordination with the power input device; the one-way valve realizes automatic clutch, and engine 6 can participate in driving or generate electricity independently to meet the needs of multiple scenarios such as heavy load, acceleration, and energy replenishment; in pure electric mode, engine 6 is automatically disconnected, with no idling resistance and no energy consumption.

[0060] The control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

Those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. Furthermore, under the teachings of this invention, modifications can be made to these features and embodiments to adapt to specific situations and materials without departing from the spirit and scope of the invention. Therefore, this invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are protected by this invention.
