The invention relates to electrodynamic devices to transmit mechanical energy from the drive shaft to the follower operating in the motor mode and the generator mode, and can be used in vehicles as an automatic variable speed and torque.

Known electro-mechanical variator with the master and the slave shaft, made in the form of electrically connected between a generator and motor having two coaxially mounted inductor with excitation windings, one of which is electrically connected to an independent source of direct current, one of the engine and the generator armature winding, crossing magnetic fluxes of both inducers that induce in it an EMF directed towards each other, and connected to its collector node, and the driving shaft of the variator is connected with ground anchor, one of the inductors is stationary, and the second inductor is made rotatable and is connected with the driven shaft of the variator (see patent SU 157707, CL NC 51/00, publ. 07.07.1990). The disadvantages of the known devices are transmitting rotation in one direction only, and the inability to connect additional sources or consumers of energy.

The invention aims to remedy these disadvantages. Technical rez is lthat is to expand the functionality of the variator. The problem is solved and the technical result is achieved by the fact that electro-mechanical variator with the master and the slave shafts made in the form of electrically connected between a generator and motor having two coaxially mounted inductor with excitation windings, one of which is electrically connected to an independent source of direct current, one of the engine and the generator armature winding, crossing magnetic fluxes of both inducers that induce in it an EMF directed towards each other, and connected to its collector node, and the driving shaft of the variator is connected with ground anchor, one of the inductors is stationary, and the second inductor made rotatable and is connected with the driven shaft of the variator, and the excitation winding of the rotating inductor is supplied with an independent collector node, configured to connect, depending on the desired direction of rotation of the driven shaft relative to the leading, independent source is DC or to the collector node of the armature winding and the field winding is stationary inductor when it is connected to the collector node of the armature winding or independent constant current source, respectively. Collector node anchors may be made in the form of collector brushes or collector who Alec with brushes and a rectifier. Collector node of the rotating inductor can be made in the form of collector brushes or brushes, collector rings and equipped with a position sensor and a device for forming and feeding the supply voltage. Through the collector node of the armature in series or in parallel with the excitation winding of one of the inductors can be connected to other independent customers/energy sources, such as a rechargeable battery.

Figure 1 shows schematically the variable with rotation of the drive and driven shafts in one direction;

figure 2 - variable with rotation of the drive and driven shafts in different directions.

Electro-mechanical variator consists of a fixed inductor 1 with the excitation winding 2, a rotating armature 3 is connected to the drive shaft 4, and a rotating coil 5 with the excitation winding 6 connected to the driven shaft 7. Anchor 3 has a coil 8, the sections of which are connected with the plates of the collector 9. Section winding 6 of the rotating inductor 5 is connected to the collector plates 10. Electrical contact with the collector plates 9 provide a fixed brush 11, and the electrical contact with the collector plates 10 provide a fixed brush 12.

The direction of magnetic flux fixed 1 and 5 rotating coils opposite each other, as shown by arrows in f is 1 and figure 2. Independent constant current source 13, depending on the desired direction of rotation of the driven shaft, nourishes winding or fixed inductor (figure 2), or rotating inductor (figure 1).

Electro-mechanical variator shown in figure 1, works as follows.

With the passage of DC current from source 13 through the brush 12 and the collector 10 through the excitation winding 6 of the rotating inductor 5, the latter occurs the magnetic flux. When rotating in the magnetic flux of the inductor 5, the armature 3 in the winding 8 is induced EMF, which through the manifold 9 and the brush 11 causes the passage of direct current through the excitation winding 2 fixed inductor 1. The passage of direct current through the excitation winding 2 fixed inductor 1 calls it the emergence of magnetic flux toward the magnetic flux of the inductor 5. When rotating in the magnetic field of the inductor 1, the armature 3 in the winding 8 is induced EMF against EMF induced magnetic field of the inductor 5, which reduces the current flowing through the coil 8 of the armature 3 and the coil 2 coil 1, reducing the magnetic flux of the latter. As a result, the current in the windings 8 and 2 is set at such a level that the difference between the EMF induced in the winding 8 of the armature 3 from crossing its magnetic flux inductors 5 and 1 compensated electrical in the Yeri in the windings 8 and 2 from passing them in DC. The interaction of the magnetic flux of the inductor 5, associated with the driven shaft 7, with the current flowing through the coil 8 of the armature 3, causes a torque on the coil 5 and it starts to rotate in the same direction as the rotation of the armature 3, is associated with the drive shaft 4 of the variator. When increasing the rotation speed of the driven shaft and its associated inductor 5 decreases the relative speed of the crossing magnetic flux of the inductor winding 5 8 anchor 3. This leads to the decrease component of the EMF induced in the winding 8 of the armature 3 from crossing its magnetic flux of the inductor 5, which, in turn, reduces the overall difference between EMF and reduces the strength of the current flowing through the windings 8 and 2. The total torque on the driven shaft is also reduced. Thus, in the electro-mechanical variator is implemented automatically reduces torque on the driven shaft with increasing speed of rotation.

Electro-mechanical variator shown in figure 2, works as follows.

With the passage of DC current from source 13 to the excitation winding 2 fixed inductor 1, the latter occurs the magnetic flux. When rotating in the magnetic flux of the inductor 1, the armature 3 in the winding 8 is induced EMF, which through the collectors 9 and 10 and the brushes 11 and 12 causes the passage of direct current through the winding of vosburg is of 6 rotating inductor 5. The passage of direct current through the excitation winding 6 of the rotating inductor 5 calls it the emergence of magnetic flux toward the magnetic flux of the inductor 1. When rotating in the magnetic field of the inductor 5, the armature 3 in the winding 8 is induced EMF against EMF induced magnetic field of the inductor 1, which reduces the current flowing through the coil 8 of the armature 3 and the winding 6 of the inductor 5, reducing the magnetic flux of the latter. As a result, the current in the windings 8 and 6 is set at such a level that the difference between the EMF induced in the winding 8 of the armature 3 from crossing its magnetic flux inductors 5 and 1 compensated electrical losses in the windings 8 and 6 from passing them in DC. The interaction of the magnetic flux of the inductor 5, associated with the driven shaft 7, with the current flowing through the coil 8 of the armature 3, causes a torque on the coil 5 and it starts to rotate in the direction opposite to the rotation of the armature 3, is associated with the drive shaft 4 of the variator. When increasing the rotation speed of the driven shaft and its associated inductor 5 increases the relative speed of the crossing magnetic flux of the inductor winding 5 8 anchor 3. This leads to increased component of the EMF induced in the winding 8 of the armature 3 from crossing its magnetic flux of the inductor 5, in the ocher is , reduces the overall difference between EMF and reduces the strength of the current flowing through the windings 8 and 6. The total torque on the driven shaft is also reduced. Thus, in the electro-mechanical variator is implemented automatically reduces torque on the driven shaft with increasing speed of rotation.

Thus, reversal of rotation of the driven shaft relative to the drive shaft is easy to carry out simple electrical switching of the windings of the variator according to the schema depicted in figure 1 and figure 2. If the brushes 11 to connect additional consumers of electricity such as a battery, electro-mechanical variable-speed drive will work not only as a torque Converter, but also as a generator of electricity. If the brushes 11 to connect an additional power source such as a battery, it will cause an additional increase in power and torque on the driven shaft.
