ELECTROMECHANICAL GEAR
The invention relates to an electro-mechanical gear assembly, comprising of the chasis, further the power transmission unit fitted inside the chasis, wherein the assembly comprises a power-in axle for torque and also the power-out axle, in between said axles locating power-transfer unit like an unit including planetary gears, to which has further been fitted an electricity-producing and torque-transferring generator assembly as well as an electrical motor assembly that rotates said axle and a control center with needed components to direct the produced electricity out of the generator assembly and also to direct electrical current into the electrical motor assembly.
The invention described in preamble above is previously known from patent publication FI- 115318, which discloses the use of an inverter in electric motor drive. The inverter is placed and fitted to rotate along with the power-out axle.
Fitting the inverter into a gear assembly to rotate along with the axle is a difficult solution and requires that the inverter has a ring-like construction and design, which in turn is very difficult to realise. It also will lengthen the axle and causes tremors along the axle, when great mass units are imposed upon the axle. On the other hand, designing the inverter to rotate does not diminish the number of electrical couplings, which must be fitted from the outside to the rotational parts of the gear assembly.
This stepless gear according to this invention offers a solution to problems in known gear assemblies, and characteristic for this invention is, that it comprises the inverter unit outside of the gear assembly itself, through which inverter electrical energy is conducted via the generator assembly to the electric motor assembly with the voltage of desired frequence for stepless adjusting of the rotation of the power-out axle.
The advantage of the gear according to this invention is that the amount of rotational mass within the gear whole has been minimized in comparison to known applications. A great amount of torque can be administered to the power-out axle, from 0-position start-outs, due to the aid of batteries which give a tremendous amount of momentary power to the electric motor assembly. The power-out axle's torque can be controlled through the easily adjustable inverter, from O-position upward and in both directions.
In the following, the invention is described in detail using the accompanying drawings, in which:
Fig. 1 shows a gear assembly from the cut-open side profile view. Fig. 2 shows a different application, as a section view from the side. Fig. 3 shows a third alternate application as a section view from the side.
The electro-mechanical gear consists of the shell-like chasis 18 along with the power-in axle 1 fitted inside of the chasis 18 and the power-out axle 2, which are not linked to rotate together. Between these two axles is a central support bearing 16. For example, a diesel motor running at constant speed rotates the power-in axle 1. The rotational torque generated by axle 1 is channeled to planetary gear 3, 5 via sun gear 17 to generator unit 8 and also secondarily by the planet gear's outer annulus 19 and the rotational cylinder-like unit 6 to electric motor compound 9 so that it turns the aforementioned motor's magnetic- field forming right half. The torque is then divided in the planetary gear into two parts and the united sum of those parts can be regulated by the outgoing electrical energy coming from generator 8, or in other words via the braking torque produced by generator 8.
When generator 8 produces electricity, the right side block of generator assembly 8 rotates at a higher speed via planetary gear 3, 5 which in turn tries to also cause the left side block to turn, which naturally brakes due to the fact that it is coupled with to the power-out axle 2, which causes a speed differential necessary for electricity production. The necessary torque to turn power-out axle 2 is produced simultaneously.
The other half of the torque is transferred via the cylinder 6 on the outside of generator assembly 8 to the electrical motor unit's 9 magnetic field producing right side half and the fixed frequency derived from the torque of electric motor 9 turns the left side half of the magnetic field producing apparatus, which is coupled with the sun gear's extended chasis 11 of planetary gear 4, 7. Through this arrangement, planetary gear 4, 7 diminishes the rotational speed and increases torque when it is channelled through flange 4 to the power- out axle 2.
The gear ratio of the gear assembly is regulated via a control panel 14, to which a sensor 15 sends information regarding the rotational speed of power-out axle 2. The torque of power-out axle 2 can also be measured here. Control panel 14 regulates the generated electricity of generator assembly 8, for example by regulating the normal conducted magnetic current of the unit. The electricity produced by generator 8 is conducted initially to battery 13. Battery 13 also feeds inverter 12 with the required voltage, causing inverter 12 to in turn feed electric motor 9 with the kind of alternating current that has been prescribed as the set value via control panel 14 at the given time. Conducted electricity to the rotational elements of the gear is brought in by gliding rings for example.
Control panel 14 also regulates the rotation of electric motor 9, in other words it regulates the mutual rotation of the left and right block. The power output of electric motor 9 at any given stage is adjustable, so that it is possible to produce varying torques to axle 2 while maintaining a constant rotational speed.
Figure 2 has a slight bit different construction as compared to Fig. 1 , in which it is possible to attain a greater torque and lesser rotational speed to the power-out axle 2 via flange 4. A greater difference of the rotation speeds between magnet fields in the generator 8 and electric motor 9 assemblies can be obtained.
Figure 3 shows cases an embodiment in which the power-in axle's 1 rotational speed is divided via flanges 20, 21 and planetary gears 22 into two different, independent rotational wholes in terms of axle 2 and the coaxial sleeve 23 attached to it. The power- out axle 2 extends all the way through the construction to flange 21 in this variation. The rotational speed subjected on the rotor flange 26 of the generator unit 8 is elevated through planetary gears 25, 30, 31. The generator unit's stator 27 is coupled with the gear chasis 18. Electric motor unit 9 consists of the flange-like rotor 28 and the stator unit 29 attached to the chasis 18.
The axles 2, 23, 25 are joined to the chasis 18 via flanges 24 and bearings. If the coils of the generator 8 and electric motor 9 assemblies locates in the parts which are fastened to the chasis 18 the mounting of electrical cables to them is easy. If electricity must be lead to the rotor parts 26 and 28 it can be done via gliding rings as known.
Although only these three embodiments that describe the working principle of the invention have been presented here, it is possible to implement the presented gear invention and technology in many other diverse gear applications, where the generator and electric motor have been placed in the shown manner to rotate in relation to one another with varying rotational speeds.
