Description

Device for generating electricity.

The present invention refers to a device for generating electric energy, capable of converting kinetic energy into electric energy. In particular, the present invention relates to an electromechanical device for the generation of electric energy, in particular, the production of alternating current which, once after being converted into direct current by means of an inverter or a diode bridge, has the double effect of recharge the batteries of an electric car and support propulsion by driving electric motors.

An alternator? consisting of a fixed hollow part, called stator, inside which rotates a cylindrical part keyed to the rotation shaft, called rotor. The rotor generates the rotating magnetic field by means of electromagnets, alternatively permanent magnets are used which do not require power. On the stator there are the electric windings on which the electromotive forces are induced which will support the electric current produced.

The main field of application ? the automotive one for recharging a vehicle battery.

How many electric vehicles are there today? constantly increasing, driven by growing investments in the production of zero-emission vehicles. They all share a fundamental problem: limited autonomy. Many of these, in fact, have an overall range ranging from 400km (in the models offered by Porsche) to a maximum of 1600km (not yet on the market, it will be a reality with the arrival of the latest models offered by Tesla). There? implies having to reload more? times your car during a trip and having to recharge them when not in use. This proposed invention, however, far? yes, the vehicles will have to be recharged very rarely. In fact, more a vehicle equipped with this technology is used, more? its batteries are recharged. Therefore, the overall autonomy does not represent more? an obstacle; the owner of a car equipped with this technology must not pi? worrying about having to stop at a specific service station where there is a fast charging tower (there are an increasing number, but very limited), as not necessary? to recharge the machine when not using it, since? it recharges when in motion.

On the other hand, the automotive company Aptera has just announced that it will soon be? available their model Aptera Paradigm, an electric vehicle whose batteries are recharged by solar panels placed on the body of the car. Although this option adopted on the Aptera Paradigm model is exceptional, does it present some difficulties? which are not found if instead this proposed technology is used.

In fact, the device of the present invention ? meteorologically independent: it recharges whether there is adverse weather (therefore any situation in which there is no sunlight) or at night. It is therefore a device that ? less vulnerable than the solar panels placed on the roof of the car, since they are positioned where there would otherwise be an internal combustion engine (therefore inside the car body).

Purpose of the present invention? that of making a mechanism for the continuous generation of electricity usable in order to autonomously recharge the batteries of the electric vehicle and to power the electric motors present (reducing the load on the batteries). To achieve this aim, the proposed generator is placed, preferably together with another specular one, inside ducts inside the vehicle body.

One aspect of the present invention relates to a device for generating electrical energy having the characteristics of the attached claim 1.

Further characteristics of the present invention are contained in the dependent claims.

With reference to the cited figures, the device (according to the present invention) comprises a turbine 100 from which the device obtains the driving torque comprising a main transmission shaft on which a driving torque is generated caused by a forced air flow which strikes this turbine , a rotor 300 placed concentrically to this main transmission shaft of the turbine which receives the rotation from this shaft and which includes alternating permanent magnets (south pole and north pole), a stator 400 placed concentrically to the bearing structure of the rotor and of the main shaft transmission comprising rolled profiles of ferromagnetic material for the insertion of copper windings necessary for the generation of alternating inductive current, when the main rotation shaft is? set in rotation by this induced air flow.

Preferably, between the main shaft and the stator ? placed a differential 200, positioned concentrically to the turbine consisting of a drive belt-drive wheel system and a gear wheel system, the presence of which makes it possible to increase the drive torque transferred to the rest of the mechanism; and that determines the rotation of the rotor in the opposite direction to the direction of rotation of the turbine and at a speed? major angular.

Furthermore, the device comprises a group of cases 500 including two semicircular cases, one lower and one upper, present for the waterproof closure, which enclose for protection and housing the pieces constituting the device according to the present invention.

Figures 3 and 4 show in detail the structure of the turbine which includes such main drive shaft 104, rotated by the interaction between the incoming air flow and a shaped head of the turbine 102. The head of the turbine 102 and the The main transmission shaft 104 are connected to each other and held in position by a screw 103 preferably with a cylindrical head. there ? then a cover 101, placed to increase aerodynamics? of the head of the turbine 102 relative to the air flow which strikes it, and to protect the screw 103 from a possible contact with a foreign body (transported by the air flow). Hooks 106 (in simplified view) of the lid are provided (they are preferably four arranged at 90° from each other) necessary to keep the lid 101 in position. A primary guide wheel 105 allows to transfer the rotation of the shaft to a secondary guide wheel 203 (Fig. 5a-5f), by means of a transmission belt 215 (Fig. 6a-6f), placed in the differential 200 which will be? analyzed later. You can also see seats of external Seeger rings (514; 303; 504), inserted to hold the ball bearings in position. In particular, the seats of the outer Seeger rings 514 and 503 will be analyzed in the future when we examine the interaction between the turbine 100 and the cases 500, while the seats of the external Seeger rings 303 when will it be described? the interaction between the turbine 100 and the rotor 300.

Figures 4a-4c illustrate a blind hole 103-A placed in the main transmission shaft 104, and the through hole of larger diameter in the head of the turbine 102 (always referred to as 103-A) in which the screw 103 is placed. The appendices 107 (positioned inside the carrier 108 of the head of the turbine 102) which together with the seats 107-A of the latter, positioned on the front part of the main transmission shaft 104, cause the head of the turbine 102 and the main transmission shaft 104 rotate at the same angular speed, without slipping on each other. Finally, can you see the arrangement of housings 106-A, positioned on the upper part of the turbine head 102, of the hooks 106 of the cover 101.

With reference to Figs. 5a-5f and Figs. 6a-6d -A, the differential 200 comprises two closing pieces, respectively a front armor 201 and a rear one 202, inside which ? the reduction mechanism is provided which comprises a shaft 206 mounted between the two armatures, on which a guide wheel 203 lies, substantially equal to the guide wheel 105 of the turbine 100, but larger? small size, and a sprocket 204. The drive belt 215 (in simplified view) ? mounted on the two guide wheels (105; 203), while the toothed wheel 204 transmits its torque to a toothed wheel 313 (mounted on the rotor 300 and of smaller dimensions than that of the differential 200). In this way, the main transmission shaft 104, rotating, rotates the shaft 206 through the transmission belt 215, which in turn feeds the rotation of the rotor 300 following the interaction between the two gear wheels respectively of the differential and rotor (204; 313). The rotor 300 rotates at a speed? angular pi? high than that of the turbine, since? the diameter of the guide wheel 105 ? greater than that of the guide wheel 203, therefore the latter rotates at a speed? superior; the guide wheel 203 and the sprocket 204 rotate at the same speed, since? placed on the same shaft 206 and the gear wheel 204 has a diameter greater than that of the gear wheel 313, therefore the latter rotates at a speed? even more superior. The differential further includes a lubrication mechanism including a nozzle 208. introduced to lubricate the contact area between the two sprockets with a liquid (unspecified), so as to slow down the wear phenomenon and decrease the thermal shock to which these two are subjected. The aforementioned mechanism also comprises a drainage channel 216, necessary for carrying the fluid to a pump (not shown) which at a later time, after having cooled the liquid with such a cooling system to a radiator (not shown), returns to circulate the fluid to the inlet of the nozzle 208. As regards the closure of the two armatures (201; 202) of the differential 200, on the rear armature 202 there are through holes 207-A (for example nine in all) and, continuing from the inside of the front armor 201, of the extruded cylinders 207 in which blind holes S-210 have been made (always nine in all). Once, after correctly aligning all the through holes 207-A and blind holes S-210, and after aligning the extruded housings 219 of the shaft 206 on the two armatures (201; 202), the same number of bolts are inserted, for example with a hexagonal head 210 to ensure correct closure of the differential 200. The differential also comprises a plastic seal 205, to be fitted before the closure described above. In fact, it ensures that the lubricating liquid does not disperse inside the entire differential 200, but ensures that it remains in an area close to that in which the gear wheels (204; 313) are located. In fact, the plastic seal 205 ? secured to the back plate 202 by three cross recessed cap screws 209; further characteristics are explained below. Appendices 211 (preferably three, equally spaced by 120?, with the defined vertical one positioned facing where the shaft 206 is, and those defined lower than 120? respectively by the latter) placed on the external surfaces of the reinforcements ( 201; 202). They serve to position the differential 200 in a correct and fixed way inside the invention itself (the AEG unit); in fact, the upper ones will be positioned in the seats S-211 present in the upper case 507, while the lower ones in the seats S-211-A of the lower case 501. They also contribute to the closing of the differential given that the through holes 218 are passed bolts that hold the piece in place, tightening it to the rest of the system. Finally, in the front armor 201 there ? a through hole 216 which allows the insertion of the turbine 100, and in the rear one there is? a through hole 217 for inserting the rotor 300; in this way the drive belt coupling 215 - guide wheels (105; 203) and the coupling between the two gear wheels (204; 313) work.

The nozzle 208 has a support plate 208-A which is welded to the bordering area of the seat S-208, placed inside the side wall of the rear armature 202. In this way there are no unwanted movements of the nozzle 208. The end ? of the mouth of the nozzle 208, in addition to decreasing in section to ensure that the liquid accelerates in output by better hitting the contact area between the two gear wheels (204; 313), has a wedge 208-B which increases the lateral dispersion of the liquid.

With regard to the plastic seal 205, on the other hand, particular attention should be paid to the following properties. There are nine through holes 205-B, in which the extruded cylinders 207 can pass, a through hole 205-C, for the passage of the main transmission shaft 104 (the smaller diameter part thereof), and a through hole 205- D, for the passage of the shaft 206. Note that all these through holes (205-B; 205-C; 205-D) all have diameters close to those of the pieces they house, to prevent high quantities? lubricant leaks (grease will also be applied to eliminate this possibility altogether).

The screws 209 for fixing the seal 205 to the rear armor 202 are placed in the through holes 205-F, placed in turn in circular bas-reliefs 205-E located on the front surface of the seal 205. On the rear surface of the seal 205, however, in correspondence with the bas-reliefs 205-E there are rectangular high-reliefs 205-A.

These bas-reliefs and high-reliefs (205-E; 205-A) are very important since they allow not to be too invasive with the screws 209, fixed in the blind holes S-209, towards the functioning of the rotating elements and to ensure that the seal does not come into contact with the gear wheels (204; 313), a situation which occurs would occur if the seal were on the same plane as the surface of the supports 202-A.

Furthermore, to understand the correct orientation of the seal, the surface of the high reliefs 205-A must coincide with the surface of the supports 202-A. The differential also comprises keys 212, to keep the guide wheel 203 and the gear wheel 204 fixed on the shaft 206, two angular bearings 213 (they can be any type) mounted in an X shape inside the housings extruded from the armatures (201; 202) (they may be mounted as preferred) to permit rotation of shaft 206. The outer rings of bearings 213 are axially located by a shoulder, while the inner rings are axially located both directions by a shaft shoulder and washer assembly. ferrule 214.

In figures 7a-7b and 8a-8e ? shown the configuration of the rotor 300 which includes a secondary transmission shaft 301, on which is located, in the front part, a gear wheel 313 which interacts with the gear wheel 204 of the differential 200. Magnets 310 (in the desired quantity), with poles alternate, are fixed, for example with a collagen, on a core comprising a front structure 312, an intermediate structure 309, a joining structure 308, a rear structure 307 and a spacer 314.

The rotor frames (312; 308; 309; 307) are held in their correct position by two sets of screws. The first, made up of cylindrical head screws with a 306 hexagonal recess, ? inserted in the through holes 314-B of the spacers 314, coupling the latter in a fixed way with the through holes S-306 dug in the secondary transmission shaft 301. The second one, however, is? consisting of tie rods 304 positioned inside the through holes in the respective rotor structures (312; 308; 309; 307; 314) and held in traction by hexagonal nuts 305.

The structure of the front rotor 312 has a through hole 312-D with a diameter similar to the external one of the secondary transmission shaft 301, necessary to be able to position it on the latter. Furthermore, there are through holes 312-C in which the tie rods 304 are positioned and, since the front structure? one of the two structures of the rotor pi? external, the nuts 305 to bring them in traction. As regards the structure of the intermediate rotor 309, it too? configured in a very similar way to the structure of the front rotor 312. always the through hole 312-D (present in all structures 312; 309; 307), necessary for the same reason. The through holes 309-C, in which the tie rods 304 are passed, are more? simple than 312-Cs since they do not involve placing dice. The last element that has a skeleton similar to the previous two? the structure of the rear rotor 307. Are there through holes 307-B, from which the ends can come out? of the tie rods 304, located on a low-relief area 307-C, designed to simplify the screwing and unscrewing operations of the nuts 305.

From a load-bearing structural point of view, on the other hand, the structure of the joining rotor simply represents a way of obtaining an external surface of the group of rotor structures (312; 309; 308; 307) which is continuous and has a greater surface area, for a greater efficient bonding of 310 magnets.

On the structure of the front rotor 312 there are extruded cylinders 312-A, to be positioned concentrically with the blind holes 308-A (equal in number to the cylinders 312-A) dug in the structure of the joining rotor 308.

On the joining structure 308 there are extruded cylinders 308-B to be coupled concentrically with the blind holes 309-B (equal in number to the cylinders 308-B) dug into the structure of the intermediate rotor 309. the intermediate structure 309 is always located between two joining structures 308, on the structure 309 there are extruded cylinders 309-A, to be positioned concentrically with the blind holes 308-A (equal in number to the cylinders 309-A) described previously. Finally, since the rear structure 307 ? the element which closes the structural skeleton of the rotor 300, blind holes 307-A have been dug out of it, into which the extruded cylinders 308-B of the joining structure 308 are inserted.

The spacer 314 also has a through hole 314-C with a diameter close to the external diameter of the secondary transmission shaft 301. described above, to be positioned concentrically with the through holes S-306 (excavated in the secondary transmission shaft 301), in which the screws 306 are inserted to couple the spacers 314 in a fixed way with the secondary transmission shaft 301 .

Furthermore, the spacer 314 has through holes 314-A. They serve to correctly align the rotor structures (312; 309; 308; 308) when they are positioned on the secondary transmission shaft 301. In fact, the through holes (312-C; 309-C; 307-B) will be placed concentrically to the through holes 314-A, and will be kept in this position by the tie rods 304.

Subsequently, on each rotor structure (312; 309; 308; 307) there are appendices 312-B.

Once the rotor structures (312; 309; 308; 307) are assembled, they cause dividers to be generated along the entire length of the external surface of the structure to keep the magnets 310 aligned. In fact, these appendages 312-B (whose number depends on how many magnets are used) are found in the same position on each of the structural elements of the rotor described above (312; 309; 308; 307).

Finally, referring again to figures 7a-7b, it can be seen the seats of the internal Seeger rings S-303 and the external ones S-315, inserted to hold the ball bearings in position. In particular, the inner circlip seats S-303 will be analyzed later when examining the interaction between the turbine 100 and the rotor 300, while the outer circlip seats S-315 when studying the interaction between the rotor 300 and the stator 400.

The stator 400 illustrated in detail in the figures in Figs. 9a-9b and 10a-10c comprises two outer plates 403, two discs of insulating material 412, laminates 404, alignment bars 402 and a cooling system 408. The two outer plates 403 are placed at both ends? of the stator 400. They are characterized by a through hole 413, necessary to house the ends? of the secondary transmission shaft 301 of the rotor 300. Subsequently, the appendices 409 are essential for fixing the stator 400 to a housing unit 500 (described below), but above all for the actual closing of the stator, which will be? secured by tie rods inserted in the through holes 411 once the device as a whole has been assembled.

The stator also comprises a bas-relief section 410, carved into the race comprised between the two lower appendices 409 of the external reinforcement 403, provided for reasons of space. In fact, in the assembled device the bas-relief section 410 ensures that there is no interference between the external armature 403 of the stator and the extruded housing 219 on the rear armature 202 of the differential 200.

Finally, note the blind holes S-402 dug into the inner surface of the outer plates 403. These are the seats where the ends will be inserted. of the alignment bars 402 (in quantity? desired), the purpose of which is ? that of not causing the laminates 404 of the stator 400 to misalign with each other. In fact, the core of the stator 400 ? created by laminates 404, placed one after the other (in desired quantity), in which the copper windings (not shown) are located. Furthermore, these copper windings can be inserted with an electrical scheme that satisfies one's functional requirements, for the production of alternating current and for the interference, of a physical nature, with the magnets 310 of the rotor.

As a result of the generation of AC current explained above, the laminated profiles 404 can become hot. For this reason, two disks of insulating material 412, having an external diameter equal to that of the external reinforcements 403, are interposed between the series of rolled profiles 404 and the two external reinforcements 403. The two external reinforcements 403, the two disks of insulating material 412 and all the rolled profiles 404 inserted must be concentric with each other along the central axis.

The cooling system? located at the external surface generated by the series of laminates 404 and ? essential to minimize the thermal variation of the latter, caused by the phenomenon previously highlighted.

It consists of a thin plate 408-B with a circumferential profile, of the same width as that of the external surface generated by the laminates 404, on which curved tubes 408-C (in the desired number) are welded. In these pipes 408-C a cooling liquid circulates (in the present invention water is considered, but it can be any desired liquid) which allows the heat exchange between the cooling system 408 and the laminated profiles 404, subtracting heat and lowering consequently the operating temperature. The path followed by the coolant should be underlined. It arrives from a pump (not shown) into an initial collection basin 405 via a hermetic coupling 401 (in simplified view). Once after the initial 405 catchment area you ? filled, the fluid begins to circulate in the pipes 408-C (besides being welded to the plate 408-B, they begin and end inside the two collection basins 405). The liquid then ends up in the final collection basin 405, to then be channeled, via the second hermetic outlet coupling 401, towards a system which cools the liquid (for example a radiator, not shown). It follows that the liquid will travel? again as described above.

The 404-A slotted profiles house the copper windings (not shown) needed to produce electrical power. 404-A Hollow Out Profiles have a shape that reflects your interests, so as they can vary in number depending on the wiring diagram you want to use,

Subsequently, ? It is possible to keep the laminated profiles 404 aligned with each other thanks to the hollowed semicircles 404-B, cut on the external diameter of the laminated profile 404. In fact, the alignment bars 402 are slid in these through holes 404-B. Likewise, along the inner surface of the plate 408-B of the cooling system 408, semicircle profiles 408-A have been hollowed out. These 408-A profiles are of fundamental importance since they allow the cooling system to slide along the assembly of the rolled profiles 404 aligned in an instant before by the alignment bars 402.

In a similar way, the configuration of the insulating material disc 412 has through holes 412-A, also with regard to the alignment bars 402. In fact, they are hollowed out to allow the passage of the alignment bars 402, arriving from the rolled profiles 404 lined up, down to the S-402 blind holes drilled into the 403 outer armor plates.

The last preliminary analysis missing ? that of the enclosure group 500, i.e. the two pieces inside which most of the elements of the invention will be placed, such as ? can be observed from Fig. 1 and Fig. 2.

The upper case visible in detail in Fig. 11 comprises an extruded semicircle profile 523 with an internal diameter close to the external diameter of the differential 200, in the middle of which ? present an identical profile 524, but with a larger internal diameter close to the external one of the cooling system 408 of the stator 400. In the front part, however, there is? an angled bulkhead 525, necessary to increase aerodynamics? of the body of the invention relative to the inlet air flow which strikes it. It should be noted that the angle of inclination of this bulkhead 525 must be such that it does not interfere with the head of the turbine 102 of the turbine 100. In the rear part of the upper case 507, on the other hand, we find a vertical bulkhead 526, on which there is a vertical bulkhead 526. a through hole equipped with a hook 508, necessary for the passage of the copper wires (not shown) arriving from the stator 400, which go towards the rest of the machine (overall electrical diagram not shown).

In particular, the through holes (S-211; S-208) allow coupling with the differential 200, while the through hole S-409 with the stator 400. Indeed, through the through hole S-208 the input of the nozzle 208, while in the through holes S-211 the appendices 211 of the differential 200.

On the other hand, the appendices 409 of the stator 400 are inserted in the through holes S-409.

In the front part, the upper case 507 comprises a major semicircular housing 511 and in the rear part a minor semicircular housing 503. In the two housings, major and minor, (511; 503) the seats S-513 and S-506 can be located respectively internal Seeger rings which keep the ball bearings in position (for housing the 100 turbine in the 500 cases).

Of fundamental importance are the appendices 517 and 514, necessary for closing the enclosure unit. How can it be analyzed from Fig. 1 (together with Fig. 11 and Fig. 12), in the through holes 518 of the appendages pi? small 517 hollow screws with hexagonal imprint 521 are inserted, to be locked by means of a nut 522. large 515 of the appendices pi? large 514, are inserted the same screws pi? large 519, blocked by a nut more? large 520. The simultaneous use of these screws (521; 519) and nuts (522; 520) allows the sealing of the cases 500, therefore of the device according to the present invention. Note that the number of appendices (517; 514) and consequently of the through holes (518; 515), of the screws (521; 519) and of the nuts (522; 520) is determined according to one's needs.

Finally, analyzing simultaneously Fig. 11 and Fig. 12 it can be seen that on the upper casing 507, between the two through holes S-211 there are two appendages 510 (the apex of which is at the same height as that of the appendages 211 of the differential 200) . Furthermore, note the through holes S-218 dug in the appendages 510, concentric with the through holes 218 dug on the appendages 211 of the differential 200, in which the? inserted a bolt (not shown) which, locked with a nut (not shown), fisser? the differential 200 inside the device.

In a similar way (always on the upper case 507), between the through holes S-409 there are two appendages 509 (of different depths) whose apex is at the same height as that of the appendages 409 of the stator 400. Again, the holes loops S-411 dug in the appendices 509, concentric with the through holes 411 dug on the appendages 209 of the stator 400, are used for inserting the tie rods (not shown) which, blocked with nuts (not shown) at the ends, guarantee the fastening of the stator 400 within the invention.

The lower case 501, shown in Fig. 12 , has a configuration very similar to that of the upper case 507. It has the same semi-circumferential profiles (523; 524) the same angled bulkhead 525 (with equal inclination angle) present in the case upper 507. A small difference is found in the vertical bulkhead 526 located in the rear area of the lower case 501. In fact, there is no? no through holes, as was the case in the 507 upper case.

Likewise, the small appendices 517, in which the through holes 518 are dug, and the large ones 514, in which there are the through holes 515, remain unchanged from those described in the paragraph concerning the upper case (see the previous paragraph as regards the closure of the lower 501 and upper 507 enclosures by means of the screws (519; 521) locked by the nuts (520; 522)).

Intuitively, also the two semicircular housings (the larger one 515 and the smaller one 502), base of the seats of the internal Seeger rings (S-513; S-506), present in the lower case 501 are the same as those described in the paragraph concerning the upper case 507.

One of the main differences between the lower case and the upper case instead, ? located in the semi-circumferential profile 524. In fact, there is a rectangular housing 516 inside which the collection basin 405 of the stator 400 is placed, once the invention has been assembled together.

A very important feature of the housing 516 are the two through holes S-401, equipped with an extruded circular crown profile, into which the hermetic couplings 401 of the stator 400 are channeled.

Referring again to Fig. 11 and Fig. 12, on the other hand, is it possible? note the through hole S-216 dug in the semi-circumferential profile 523 (adjacent to the angled bulkhead 525), in which it will pass? the drain 216 of the differential 200. In addition, on the lower case 501 the lower appendages 211 of the differential 200 and the lower appendages 409 of the stator 400 will no longer be? inlets orthogonal to the plane as in the 507 upper housing, but will be at a precise angle (defined by your requirements) from the reference plane. Consequently, the through holes S-211-A, into which the four lower appendages 211 of the differential 200 will pass, and the through holes S-409-A, into which the four lower appendages 409 of the stator 400 will pass, will be also excavated at the same angle from the reference plane.

Despite this, the appendages 510, with the respective through holes dug S-218, and the appendages 509, with the through holes dug S-411, will be in two series, no longer? only one as on the upper case 507, but still maintaining all the properties? analyze the first time.

Finally, it should be noted that the through holes (S-211-A; S-409-A) are no longer? centered relative to the appendices (510; 509) respectively, as happened instead in the upper case 507.

This characteristic ? made necessary by the fact that the through holes (S-211-A; S-409-A) are dug in a point of the circular surface not perpendicular to the direction of insertion of the lower appendages (211; 409) and the lower appendages 211 of the differential 200 and the lower lugs 409 of the stator 400 are extruded at an angle from the reference plane.

Therefore, it is necessary to have through holes (S-211-A; S-409-A) more? wide to allow correct insertion of the lower appendages (211; 409). In a second moment then, the section cut in pi? in the through holes (S-211-A; S409-A) will come? sealed with strong adhesives (or any other applicable viscous insulating material).

For the analysis of the way in which the various elements of the device according to the present invention are positioned within the invention, refer to Fig. 1 and Fig. 2.

Consider the 100 turbine on which ? The ball bearing 512 has been placed, and maintained in position by the external Seeger ring 514, installed after closing the head of the turbine 102 on the main transmission shaft 104. It (turbine 100) is coupled with the differential 200 by passing the transmission main shaft 104 concentrically in the two through holes (216; 217) of the two armatures (201; 202).

Subsequently, note how: a) the extremity? rear of the main shaft 104 of the turbine 100 passes through the front armature 201 first, so that the guide wheel 105 (simplified) of the turbine 100 is aligned with the guide wheel 203 (simplified) more? small of the differential; b) the drive belt 215 (in simplified view has been mounted on the guide wheel 203 of the differential 200 after closing the two armatures (201; 202); c) the play present between the two through holes (216; 217) of the differential 200 and the main transmission shaft 104 of the turbine 100 allows the two guide wheels (105; 203) to approach each other, to make possible the correct positioning of the transmission belt 215.

Once after positioning the differential 200 on the turbine 100, the rotor 300 is inserted. The secondary drive shaft 301 of the rotor is coupled concentrically with the main drive shaft 104 of the turbine 100 and with the through hole 217 of the differential 200, by entering first the front where ? located sprocket 313. What? doing, the sprocket 313 of the rotor 300 will be? aligned with the toothed wheel 204 of the differential 200, ensuring correct meshing of the two and correct functionality? of the differential 200 (the purpose of which is to make the rotor 300 rotate at a higher number of revolutions per minute than that of the turbine 100). This connection is then terminated by inserting the ball bearings 302 (in a quantity defined by your needs), whose outer and inner rings are kept in position by the pair of outer and inner Seeger rings 303, inside between the inner of the secondary drive shaft 301 and the outside of the main drive shaft 104 (of the rotor 300 and turbine 100 respectively). Particular importance must be placed on the following facts: a) on the secondary transmission shaft 301 of the rotor 300, before coupling the rotor 300 with the turbine 100, the external armature 403 placed in front of the stator must be installed. Therefore, where there are the S-315 seats of the external Seeger rings (near the 313 toothed wheel), will it come? concentrically mounted (on the rotor 300) the outer armature 403 of the stator 400 with a ball bearing 405, held in position by the outer Seeger rings 406 and the inner Seeger ring 407, passing the secondary transmission shaft 301 through the through hole 413 of the armature 403.

Indeed, isn't it? is it possible to place the stator 400 on the rotor 300 already? assembled, since the rotor structures (307; 308; 309; 312) could not pass through the through hole 413. The gear pattern (105; 203; 204; 313) located in the differential 200 and the belt configuration of transmission 215 causes the rotor 300 to rotate in the opposite direction with respect to the direction of rotation of the turbine 100. This characteristic ? been introduced to avoid the phenomenon of resonance between the rotor 300 and the rotating turbine 100, a phenomenon which would generate vibrations harmful to the structure and the correct functioning of the invention (keep in mind that if not desired, this peculiarity can be excluded by implementing a last guide wheel which allows the belt 215 to hook, with its outer surface, to the guide wheel 203).

The positioning of the stator 400 follows. It is placed concentrically with the rotor 300, on whose secondary transmission shaft 301 (close to the differential 200) is? already positioned the second armature 403 placed in front of the stator 400.

When the stator 400 is positioned as discussed above, the second ball bearing 405 is inserted onto the secondary transmission shaft 301, held in position by the outer Seeger rings 406 and the inner Seeger ring 407.

Going forward, one very important aspect must be highlighted. Up to now we have not paid much attention to how the subsystems are placed relative to each other, other than being concentric with respect to an imaginary axis running through the turbine 100 (along its entire length). In fact, the relative positioning of the first four subsystems begins to present itself as a criticality? when the two closure cases of the invention are positioned, i.e. the lower one 501 and the upper one 507.

The assembly consisting of the turbine 100, the differential 200, the rotor 300 and the stator 400 is housed in it once after having aligned the various appendices present (211 and 216 of the differential 200, 409 of the stator 400) with the through holes S -211-A and S-409-A dug into the lower case 501. Similarly, the collection basin 405 and the two permeable hermetic latches 401 of the stator 400 must be aligned with the rectangular housing 516 and with the two through holes S-401 present on the lower case.

Before positioning these four subassemblies (100; 200; 300; 400) in the lower case 501, however, it is necessary to insert the ball bearing 505, held in position by a shaft shoulder and an external Seeger ring 504, on the 'end? final of the main transmission shaft 104 of the turbine 100.

In this way, since? the ball bearing 512 was already? been positioned, the rotating elements of the turbine 100, differential 200, rotor 300 and stator 400 assembly will be free to rotate inside the non-flexible structural elements fixed to the housing assembly 500.

Therefore, the ball bearings (512; 505) are put into position in the semicircular housings (515; 502) of the lower case 501, inserting the various Seeger rings (514; 513; 504; 506), together with the internal structure (100; 200; 300; 400) of the invention.

The complete closure of the device of the present invention takes place with the simple positioning of the upper case 501 on the rest of the creation already? assembled.

In fact, from the moment in which the sub-assemblies (100; 200; 300; 400) have been correctly oriented to be able to be inserted in the lower case 501, all the upper appendages (211 and 208 of the differential 200; 409 of the stator 400) are already aligned with the respective through holes (S-211; S-208; S-409) dug in the upper case 507.

Furthermore, the ball bearings (512; 505) and Seeger rings (514; 513; 504; 506) must be aligned correctly, already? present, with their respective headquarters in the lodgings (511; 503).

Finally, to conclude the construction of the complete assembly, ? necessary to perform the following steps:

the. Seal the two housings (501; 507) together with the screws (519; 521) and nuts (520; 522). Note that you can insert a waterproof sheath between the two mating profiles of the enclosures (501; 507), to insulate the internal electrical system of the unit from external liquids.

ii. Assemble, and fix in position with the screw 103, the head of the turbine 102 (with the relative cover 101) on the main transmission shaft 104. In fact, it is placed last in such a way as to allow to: a) position the ball bearing 512 on the main drive shaft 104; b) position the two cases (501; 507), whose positioning would not be possible otherwise since? the angled bulkheads 525 would impinge on the outer edge of the turbine head 102; c) put in position and fix the screws 521 and the nuts 522.

iii. Pass the bolts (not shown) and the tie rods ( not shown) which, once fixed by nuts (not shown), make it possible to hook and position the assembly inside the engine compartment of the motor vehicle.

Figure 13 illustrates a possible positioning of the device of the present invention in a vehicle. By way of non-limiting example, the proposed invention is placed in the aforementioned vehicles with the aim of recharging the batteries and, at the same time, activating the electric motors which move the vehicle itself.

In a vehicle, equipped with an engine compartment, can? at least one device can be positioned on a rigid structure 601 situated in the engine compartment which is in turn constrained to the body of the motor vehicle. For this purpose, the device comprises at least one duct 602 for conveying the air flow towards the turbine 100 and at least one air outlet 603 located behind the turbine itself.

In the embodiment illustrated in figure 13, the devices positioned in the engine compartment are two 1 and 1' side by side, each equipped with a respective duct for conveying the air 602 and 602' and an exhaust duct 603 and 603'.

The conveyance ducts are concentric with the respective devices and extend from the front part of the vehicle (where the air flow enters) to the initial part of the body (where the structure 601 which supports the device is coupled thereto). The air flow enters from the front of these ducts, continues up to the device of the invention for actuating it and is finally expelled from the outlets which are advantageously angled grille. The drains can also be without a grid, but is it? recommended as it directs the outgoing air flow in a direction close to that of the air which strikes the external surface of the car. In fact, if the air were to leave perpendicular to the direction of motion of the external air, turbulence would be created which would affect the efficiency of the invention.

The two units? they are kept in position, with respect to the rigid structure, by shock absorbers, which hook on one side to the appendices of the differential and to those of the stator, on the other to seats in the rigid structure in which there are through holes. The use of these shock absorbers ? recommended because, together with the suspension of the wheels of the vehicle, they dampen the pi? possible all the vibrations that could be harmful to the integrity? of the device.

The ducts are fixed to vertical pipes 604 of the rigid structure by hooks connected to the various sections of the duct, closed in turn by single hooks equal to those of the single sections of the duct.

Where the buffers cross the pipes, the pipes have a through hole to allow the buffers to be positioned. The through holes in the ducts in which the hydraulic pipes of the nozzle and of the differential collection basin pass, the pipes of the stator cooling system and the electric circuit arriving from the stator to the rest of the vehicle, are not shown as the their recommended position depends on how the rest of the other elements necessary for their correct functioning (such as the pump unit and the system for converting alternating current into direct current) are positioned inside the vehicle.
