Detailed Description

The present invention will be described in further detail with reference to examples and embodiments. It should be understood that the scope of the above-described subject matter is not limited to the following examples, and any techniques implemented based on the disclosure of the present invention are within the scope of the present invention.

Example 1

As shown in fig. 1, the present invention provides a transmission based on electromagnetic effect for adjusting a rotation speed between a power source and a wheel, including a first driving shaft and a first driven shaft, the first driving shaft is sleeved on one side of a force component mechanism (i.e. one part of the first driving shaft is outside the force component mechanism, and the other part is inside the force component mechanism), the first driven shaft is sleeved on the top of the force component mechanism (i.e. one part of the first driven shaft is outside the force component mechanism, and the other part is inside the force component mechanism), the first driving shaft and the first driven shaft realize electromagnetic induction inside the force component mechanism, and the force component mechanism is a square birdcage coil. The angle between first driving shaft and the first driven shaft is A, and 80 degrees is more than or equal to A and is less than or equal to 90 degrees, and the benefit of angle setting is that the intensity of electromagnetic induction between first driving shaft and the first driven shaft is great, if the angle continues to reduce or increase, the electromagnetic induction intensity between the two is less, reduces the efficiency that the rotational speed was adjusted on the contrary. First driving shaft and first driven shaft all need bearing to support, avoid appearing great vibrations when high-speed rotatory.

In the present embodiment, as shown in fig. 2, a first driving shaft located inside the force component mechanism is wound with N (N is a positive integer) coils, each of which is connected by a second switch, each of which is connected to the first driving shaft current controller.

The first driving shaft is connected with an engine, when the engine is started, the first driving shaft drives the coil to rotate, and the coil on the first driving shaft is electrified to generate a magnetic field. The first driving shaft current controller can respectively control the on-off of the second on-off device so as to control the number of coils electrified by the first driving shaft and further control the intensity of the magnetic field; the intensity of the magnetic field can also be controlled by adjusting the current.

In this embodiment, as shown in fig. 3, M (M is a positive integer) coils are wound around a first passive shaft located inside the force component mechanism, each coil is connected through a first on-off device, and each first on-off device is connected to a first passive shaft current controller.

The first driven shaft is connected with a rear wheel end shaft of the vehicle to control the rotating speed of a rear wheel, and two-wheel drive is realized. When the coil on the first driving shaft is electrified to generate a magnetic field, the coil on the first driven shaft is simultaneously electrified, the coil on the first driving shaft and the coil on the first driven shaft can generate an electromagnetic mutual inductance effect, the first driving shaft drives the first driven shaft to rotate, and then the wheel end shaft is driven to rotate. The first driven shaft current controller can respectively control the on-off of the first on-off device so as to control the number of coils electrified by the first driven shaft and further control the intensity of the magnetic field on the first driven shaft, and also can control the intensity of the magnetic field on the first driven shaft by adjusting the current, so that the rotating speed of the first driven shaft is changed.

In this embodiment, when the number of coils or the magnitude of the current applied to the first driving shaft is changed, the magnetic force applied to the first driven shaft is changed, and the rotation speed of the second driven shaft is changed. For example, when the number of the first driving shaft coils is increased or the current is increased, the magnetic force applied to the first driven shaft is increased, and the rotating speed of the second driven shaft is increased; for example, when the number of the first driving shaft coils is decreased or the current is decreased, the magnetic force applied to the first driven shaft is decreased, and the rotational speed of the second driven shaft is decreased.

In this embodiment, the power transmission device further comprises a second driving shaft, and the second driving shaft is sleeved on the other side edge of the force component mechanism opposite to the first driving shaft. And a second driving shaft positioned in the force component mechanism is wound with N (N is a positive integer) coils, each coil is connected through a fourth breaker, and each fourth breaker is connected to a second driving shaft current controller. The second driving shaft is connected with the motor, when the motor is started, the second driving shaft drives the coil to rotate, and the coil on the second driving shaft is electrified to generate a magnetic field. The second driving shaft current controller can respectively control the on-off of the fourth on-off device so as to control the number of coils electrified by the second driving shaft and further control the intensity of the magnetic field; the strength of the magnetic field can also be controlled by adjusting the magnitude of the current.

In this embodiment, the power source includes an engine and a motor, and the driving force transmission is performed through the first driving shaft and the second driving shaft, respectively, so as to realize the driving force combination of multiple power sources. For example, the first driving shaft is connected with an engine, and the second driving shaft is connected with an electrode, so that the driving of multiple power sources can be realized.

In this embodiment, the component force mechanism further includes a second driven shaft, and the second driven shaft sleeve is disposed on the bottom side of the component force mechanism opposite to the first driven shaft. And M (M is a positive integer) coils are wound on a second driven shaft positioned in the force component mechanism, each coil is connected through a third breaker, and each third breaker is connected to a second driven shaft current controller.

The second driven shaft is connected with a front wheel end shaft of the vehicle to control the rotating speed of a front wheel, and is matched with the first driven shaft to realize four-wheel drive. When the coils on the first driving shaft or/and the second driving shaft are electrified to generate a magnetic field, the coils on the second driven shaft are simultaneously electrified, and then the coils on the first driving shaft or/and the second driving shaft and the coils on the second driven shaft can generate an electromagnetic mutual inductance effect, so that the second driven shaft rotates, and further the front wheel end shaft is driven to rotate. The second passive shaft current controller can respectively control the on-off of the third on-off device so as to control the number of coils electrified by the second passive shaft and further control the intensity of the magnetic field; the intensity of the magnetic field can also be controlled by adjusting the current.

In the embodiment, two-wheel drive and four-wheel drive of the vehicle are realized through electromagnetic induction between the first driving shaft or/and the second driving shaft and the first driven shaft or/and the second driven shaft. Meanwhile, the rotating speed of the driven shaft is adjusted by adjusting the number of the electrified coils or/and the current to adjust the strength of the magnetic field. The second driving shaft and the second driven shaft are supported by bearing supports, so that large vibration is avoided when the second driving shaft and the second driven shaft rotate at high speed.

Example 2

The force component structure is a spherical coil, and the other structure is the same as that of embodiment 1.

As shown in FIG. 4, the coil starts to rotate at an angle θ when the first driving shaft is energized, and the first driving shaft is rotatedThe coil does circular motion around the first point driving shaft, and the angle between the real-time position of rotation and the initial position of the coil is theta for any point on the coil; the voltage between the two ends of the coil R1 and R2 is V_r. When the first driven shaft or/and the second driven shaft are electrified, magnetic field induction is respectively generated between the first driven shaft and the first driving shaft, and the output voltage between the two ends S3 and S1 of the first driven shaft coil is V_bThe output voltage between the two ends S4 and S2 of the second passive shaft coil is V_a，

V_r＝V_p×Sin(wt)，V_a＝V_s×Sin(wt)×Cos(θ)，V_b＝V_s×Sin(wt)×Sin(θ) (1)

In the formula (1), θ represents an angle between a real-time position and an initial position of the rotation of the first driving shaft coil; v_rRepresenting a reference voltage across the first active shaft coil; v_pThe proportional voltage is expressed and can be adjusted according to a PWM signal of the controller; ω represents the frequency of rotation of the first drive shaft coil; v_aRepresenting the output voltage across the second passive shaft coil; v_sRepresenting a sampled voltage on the second passive shaft coil; v_bRepresenting the output voltage across the first passive axis coil.

In this embodiment, for example, if the number of the coils energized to the first driving shaft is 4, the rotation speed of the first driven shaft is 2000r/min, and if the number of the coils energized to the first driving shaft is 6, the rotation speed of the first driven shaft is 3000 r/min.

B. The first power source is started and drives the first driving shaft to rotate, the second power source is started and drives the second driving shaft to rotate simultaneously, the first driving shaft, the second driving shaft and the first driven shaft are powered by coils, the first driving shaft and the second driving shaft jointly drive the first driven shaft to rotate, the number of electrified coils on the first driving shaft and the second driving shaft is adjusted in real time so as to adjust the rotating speed of the first driven shaft, and therefore two driving of a vehicle is achieved.

C. The method comprises the steps that a first power source is started and drives a first driving shaft to rotate or a second power source is started and drives a second driving shaft to rotate, power is supplied to coils on the first driving shaft or the second driving shaft and a first driven shaft and a second driven shaft, the first driving shaft or the second driving shaft drives the first driven shaft and the second driven shaft to rotate, and the rotating speeds of the first driven shaft and the second driven shaft are adjusted by adjusting the number of electrified coils on the first driving shaft or the second driving shaft in real time; the rotating speed regulation specific gravity of the first driven shaft is 0.7 (the rotating speed regulation specific gravity comprises a fixed proportion of 0.7 and a variable proportion of sin theta), the rotating speed regulation specific gravity of the second driven shaft is 0.3 (the rotating speed regulation specific gravity comprises a fixed proportion of 0.7 and a variable proportion of cos theta), and the rotating speed regulation specific gravity represents the proportion of the induced voltage distributed to the driven shaft by the first driving shaft, so that the four-wheel drive of the vehicle is realized.

D. The method comprises the steps that a first power source is started and drives a first driving shaft to rotate, a second power source is started and drives a second driving shaft to rotate, coils on the first driving shaft, the second driving shaft, a first driven shaft and a second driven shaft are powered simultaneously, the first driving shaft and the second driving shaft jointly drive the first driven shaft and the second driven shaft to rotate, and the rotating speeds of the first driven shaft and the second driven shaft are adjusted by adjusting the number of electrified coils on the first driving shaft and the second driving shaft in real time; the rotating speed of the first driven shaft is adjusted to have the specific gravity of 0.7, and the rotating speed of the second driven shaft is adjusted to have the specific gravity of 0.3, so that the four-wheel drive of the vehicle is realized. Therefore, the input and multi-shaft output driving of a plurality of power sources can be realized, and the rotating speed and the speed of the vehicle can be improved.

When the power source stops working and the vehicle still runs slowly, the wheel end shaft drives the electrified first driven shaft or second driven shaft to rotate, the first driving shaft or second driving shaft is driven to rotate through electromagnetic induction, and the first driving shaft or second driving shaft outputs electric energy to the power source, so that energy recovery is realized.
