[0011] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0012] Embodiment 1, in combination with Figure 1 , a magnetic induction transmission and power generation hybrid system, including an engine 1, a flywheel 2, a locking device 3, an inner rotor 4, an outer rotor 5, a rotor 6, a stator 7, a transmission shaft 8, a control device and a battery pack 11;

[0013] The flywheel 2 is the power output wheel of the engine 1, the inner rotor 4 is fixedly mounted on the flywheel 2, the outer rotor 5 is fixedly connected to the rotor 1 6, the outer rotor 5 is sleeved on the outside of the inner rotor 4, the locking device 3 is fixedly mounted on the outer rotor 5, when the locking device 3 is working, the outer rotor 5 is relatively fixed to the inner rotor 4, the rotor 1 6 is rotationally connected to the stator 7, and the transmission shaft 8 is fixedly connected to the rotor 1 6;

[0014] The inner rotor 4 , the outer rotor 5 , the stator 7 , the locking device 3 are electrically connected to the control device and the battery pack 11 .

[0015] The transmission shaft 8 is connected to a reduction gear 9 of the vehicle.

[0016] During specific implementation, the engine 1 and the stator 7 are fixedly mounted on the frame of the automobile and cannot rotate. The inner rotor 4 is electromagnetic, the outer rotor 5 is a coil, the rotor 1 is electromagnetic or permanent magnet, and the stator 7 is a coil.

[0017] In the initial stage of vehicle starting, the vehicle is stationary, and the engine 1 is started (the engine passes the low speed range, slightly higher speed, and enters the high thermal efficiency range), and the flywheel 2 drives the inner rotor 4 to rotate. At this time, the outer rotor 5 is stationary. The inner rotor 4 and the outer rotor 5 cooperate to be equivalent to a generator. The inner rotor 4 is the generator rotor, and the outer rotor 5 is the generator stator. When the excitation current of the inner rotor 4 and the output current of the outer rotor 5 are changed, the torque of the inner rotor 4 on the outer rotor 5 will change. Increasing the excitation current of the inner rotor 4, the current output by the outer rotor 5 increases, and the torque of the inner rotor 4 on the outer rotor 5 will also increase. The electric energy generated by the outer rotor 5 charges the battery through the control device, and then is transmitted to the stator 7 as needed. The rotor 6 and the stator 7 are equivalent to the motor. The rotor 6 is the rotor of the motor to generate a rotational torque. The torque of the rotor 6 and the outer rotor 5 acts on the transmission shaft 8 at the same time, and the vehicle starts. The vehicle speed gradually increases. With the increase of the vehicle speed, the relative speed of the inner rotor 4 and the outer rotor 5 decreases, and the electric energy output by the outer rotor 5 gradually decreases. The control device controls the current output to the stator 7 to gradually increase. After reaching a certain vehicle speed, the engine speed is controlled to make the speeds of the flywheel 2 and the locking device 3 close to synchronization. At the same time, the locking device 3 works. After locking, it stops outputting excitation current to the inner rotor 4, and the outer rotor 5 no longer generates electricity, so that the engine power is directly transmitted to the main reducer (without a gearbox in the traditional sense), and the transmission efficiency is the highest.

[0018] When the vehicle is traveling at a low speed, the engine 1 can be operated intermittently to charge the battery at an economic speed, and stop running when the battery is basically fully charged, and only the rotor 6 and the stator 7 are used to drive the vehicle.

[0019] When going downhill or braking, the control device converts the rotor 6 and the stator 7 into generators to recover energy for charging the battery.

[0020] When reversing, just change the connection method of stator 7 to make rotor 6 rotate in the opposite direction.

[0021] In this solution, the battery capacity can also be increased, the power of the motor (rotor 6 and stator 7) can be increased, and the control logic of the control device can be changed to make it a plug-in hybrid.

[0022] It is also possible to add a set of devices to the outer rotor 5 and the rotor 6 to enable them to be separated and engaged. When in the engaged state, it is the same as described above and will not be introduced here. When in the separated state: the outer rotor 5 is locked and fixed while separating so that it cannot rotate, which is equivalent to the stator of a generator. The rotor 6 can rotate together with the transmission shaft 8, thus becoming an extended-range vehicle.

[0023] In addition, other transmission systems that require stepless speed regulation can also refer to this transmission method.

[0024] In the description of the embodiments of the present invention, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the invented product is usually placed when used. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0025] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] In the description of the embodiments of the present invention, "plurality" means at least 2.

[0027] In the description of the embodiments of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The present invention and its implementation methods are described above, which is not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and design structural principles, methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention, they should all fall within the protection scope of the present invention.
