del brevetto per Invenzione Industriale dal titolo: of the patent for Industrial Invention entitled:
“VEICOLO STRADALE CON PROPULSIONE IBRIDA†⠀ œROAD VEHICLE WITH HYBRID PROPULSIONâ €
SETTORE DELLA TECNICA TECHNIQUE SECTOR
La presente invenzione à ̈ relativa ad un veicolo stradale con propulsione ibrida. The present invention relates to a road vehicle with hybrid propulsion.
ARTE ANTERIORE ANTERIOR ART
Un veicolo stradale ibrido comprende un motore a combustione a combustione interna, il quale trasmette la coppia motrice alle ruote motrici mediante una trasmissione provvista di un cambio, ed almeno una macchina elettrica che à ̈ collegata meccanicamente alle ruote motrici. La macchina elettrica viene pilotata da un azionamento elettrico collegato ad un sistema di accumulo elettrico tipicamente costituito da un pacco di batterie chimiche eventualmente collegate in parallelo ad uno o più supercondensatori. A hybrid road vehicle comprises an internal combustion combustion engine, which transmits the drive torque to the drive wheels by means of a transmission equipped with a gearbox, and at least one electric machine which is mechanically connected to the drive wheels. The electric machine is driven by an electric drive connected to an electric storage system typically consisting of a pack of chemical batteries possibly connected in parallel to one or more supercapacitors.
Durante la marcia del veicolo stradale à ̈ possibile: una modalità di funzionamento termica, in cui la coppia motrice à ̈ generata solo dal motore a combustione ed eventualmente la macchina elettrica opera come generatore per ricaricare il sistema di accumulo elettrico; una modalità di funzionamento elettrica, in cui il motore a combustione à ̈ spento e la coppia motrice à ̈ generata solo dalla macchina elettrica operante come motore; oppure una modalità di funzionamento combinata, in cui la coppia motrice à ̈ generata sia dal motore a combustione, sia dalla macchina elettrica operante come motore. Inoltre, per aumentare l’efficienza energetica complessiva durante tutte le fasi di decelerazione, la macchina elettrica può venire utilizzata come generatore per realizzare una decelerazione rigenerativa in cui l’energia cinetica posseduta dal veicolo stradale invece di venire completamente dissipata in attriti viene in parte convertita in energia elettrica che viene immagazzina nel sistema di accumulo elettrico. While the road vehicle is running, it is possible to: a thermal operating mode, in which the engine torque is generated only by the combustion engine and possibly the electric machine operates as a generator to recharge the electrical storage system; an electric mode of operation, in which the combustion engine is off and the engine torque is generated only by the electric machine operating as an engine; or a combined operating mode, in which the engine torque is generated both by the combustion engine and by the electric machine operating as an engine. Furthermore, to increase the overall energy efficiency during all the deceleration phases, the electric car can be used as a generator to achieve a regenerative deceleration in which the kinetic energy possessed by the road vehicle instead of being completely dissipated in friction is part converted into electrical energy which is stored in the electrical storage system.
Il piazzamento del sistema di accumulo all’interno del veicolo stradale può risultare molto complesso particolarmente nel caso di un veicolo stradale sportivo ad alte prestazioni che presenta degli spazi interni molto ridotti. In particolare, il sistema di accumulo deve possibilmente venire disposto in prossimità della macchina elettrica e dell’azionamento elettrico per ridurre la lunghezza dei cavi elettrici di collegamento (quindi per ridurre il peso dei cavi elettrici e le perdite di potenza per effetto Joule nei cavi elettrici stessi), deve possibilmente venire disposto in posizione protetta dagli urti, deve venire disposto in posizione riparata dalle fonti di calore in quanto non sopporta temperature elevate, e deve venire disposto in modo da non sbilanciare con la propria massa rilevante l’equilibrio del veicolo stradale (in altre parole, il più vicino possibile al baricentro ed al terreno per ottenere un buon comportamento dinamico del veicolo stradale). The placement of the accumulation system inside the road vehicle can be very complex, particularly in the case of a high performance sports road vehicle which has very limited interior spaces. In particular, the storage system must possibly be placed near the electric machine and the electric drive to reduce the length of the electric connection cables (therefore to reduce the weight of the electric cables and the power losses due to the Joule effect in the cables themselves), it must possibly be placed in a position protected from shocks, it must be placed in a position sheltered from heat sources as it cannot withstand high temperatures, and it must be arranged in such a way as not to unbalance the balance of the road vehicle (in other words, as close as possible to the center of gravity and the ground to obtain good dynamic behavior of the road vehicle).
Nei veicoli noti, i sopra descritti vincoli costringono a disporre le batterie del sistema di accumulo in posizioni non ottimali e comunque limitano notevolmente lo spazio utilizzabile per le batterie del sistema di accumulo; di conseguenza, la capacità di immagazzinare energia elettrica del sistema di accumulo risulta limitato e di conseguenza anche le possibilità di utilizzo della macchina elettrica risultano ridotte. In known vehicles, the above-described constraints force the batteries of the storage system to be arranged in non-optimal positions and in any case considerably limit the usable space for the batteries of the storage system; consequently, the capacity of the storage system to store electrical energy is limited and consequently the possibility of using the electrical machine is also reduced.

Il sistema 4 di motopropulsione ibrido comprende un motore 5 termico a combustione interna, il quale à ̈ disposto in posizione anteriore ed à ̈ provvisto di un albero 6 motore, una trasmissione 7 servocomandata, la quale trasmette la coppia motrice generata dal motore 5 a combustione interna verso le ruote 3 posteriori motrici, ed una macchina 8 elettrica reversibile (cioà ̈ che può funzionare sia come motore elettrico assorbendo energia elettrica e generando un coppia meccanica motrice, sia come generatore elettrico assorbendo energia meccanica e generando energia elettrica) che à ̈ meccanicamente collegata alla trasmissione 7 servocomandata. The hybrid propulsion system 4 comprises an internal combustion thermal engine 5, which is arranged in the front position and is provided with a drive shaft 6, a servo-controlled transmission 7, which transmits the drive torque generated by the combustion engine 5 internal to the 3 rear driving wheels, and a reversible electric machine 8 (that is, which can work both as an electric motor absorbing electric energy and generating a mechanical driving torque, and as an electric generator absorbing mechanical energy and generating electric energy) which is mechanically connected to servo-controlled transmission 7.
La trasmissione 7 servocomandata comprende un albero 9 di trasmissione che à ̈ da un lato à ̈ angolarmente solidale all’albero 6 motore e dall’altro lato à ̈ meccanicamente collegato ad un cambio 10, il quale à ̈ disposto in posizione posteriore e trasmette il moto alle ruote 3 posteriori motrice mediante due semiassi 11 che ricevono il moto da un differenziale 12. La macchina 8 elettrica reversibile à ̈ meccanicamente collegata al cambio 10 ed à ̈ pilotata da un azionamento 13 elettrico collegato ad un sistema 14 di accumulo (illustrato nella figura 2), il quale à ̈ atto ad immagazzinare energia elettrica e comprende una serie di dispositivi 15 di accumulo comprendenti a loro volta batterie chimiche e/o supercondensatori. The servo-controlled transmission 7 comprises a transmission shaft 9 which is on one side angularly integral with the motor shaft 6 and on the other side is mechanically connected to a gearbox 10, which is arranged in a rear position and transmits motion to the rear drive wheels 3 by means of two drive shafts 11 which receive motion from a differential 12. The reversible electric machine 8 is mechanically connected to the gearbox 10 and is piloted by an electric drive 13 connected to a storage system 14 ( shown in Figure 2), which is suitable for storing electrical energy and comprises a series of storage devices 15 which in turn comprise chemical batteries and / or supercapacitors.
Secondo quanto illustrato nella figura 2, il veicolo 1 stradale à ̈ provvisto di un telaio 16 che supporta direttamente il sistema 4 di motopropulsione ed appoggia sulle ruote 2 anteriori e sulle ruote 3 posteriori mediante l’interposizione di rispettive sospensioni 17 anteriori e di rispettive sospensioni 18 posteriori. According to what is illustrated in figure 2, the road vehicle 1 is provided with a frame 16 which directly supports the motor-propulsion system 4 and rests on the front wheels 2 and on the rear wheels 3 through the interposition of respective front suspensions 17 and respective 18 rear suspension.
Secondo quanto illustrato nella figura 3, il veicolo 1 comprende una carrozzeria 19 che riveste il telaio 16, definisce un abitacolo 20 e presenta almeno due portiere 21 di accesso all’abitacolo 20 stesso. Al di sotto di ciascuna portiera 21, à ̈ definito un rispettivo brancardo 22 (cioà ̈ la parte inferiore del sottoporta che si estende dalla fine dell'arco passaruota anteriore fino all'inizio dell'arco passaruota posteriore), in cui à ̈ disposto un longherone 23 longitudinale del telaio 2 (illustrato nelle figure 4 e 5) che quindi à ̈ disposto in corrispondenza di un bordo laterale del telaio 2 al di sotto di una portiera 21. According to what is illustrated in Figure 3, the vehicle 1 comprises a body 19 which covers the frame 16, defines a passenger compartment 20 and has at least two doors 21 for accessing the passenger compartment 20 itself. Below each door 21, a respective sill 22 is defined (i.e. the lower part of the sill extending from the end of the front wheel arch to the beginning of the rear wheel arch), in which a longitudinal longitudinal member 23 of the frame 2 (illustrated in Figures 4 and 5) which is therefore arranged at a lateral edge of the frame 2 under a door 21.
Secondo quanto illustrato nelle figure 2, 4 e 5, il veicolo 1 stradale comprende un tunnel 24 centrale, il quale à ̈ fissato al telaio 16, corre centralmente e longitudinalmente dal motore 5 termico a combustione interna al cambio 10 ed alloggia l’albero 9 di trasmissione. Inoltre, il veicolo 1 stradale comprende un pianale 25, il quale à ̈ fissato al telaio 10, costituisce una parete di fondo dell’abitacolo 20, ed à ̈ costituito da due lamiere sostanzialmente piane disposte simmetricamente da lati opposti del tunnel 24 centrale. Sopra al pianale 25 à ̈ disposto un rivestimento 26, il quale costituisce una finizione dell’abitacolo 20 ed in particolare costituisce una pavimentazione a vista dell’abitacolo 20. As illustrated in figures 2, 4 and 5, the road vehicle 1 comprises a central tunnel 24, which is fixed to the frame 16, runs centrally and longitudinally from the internal combustion engine 5 to the gearbox 10 and houses the shaft 9 of transmission. Furthermore, the road vehicle 1 comprises a platform 25, which is fixed to the frame 10, constitutes a bottom wall of the passenger compartment 20, and consists of two substantially flat sheets arranged symmetrically on opposite sides of the central tunnel 24. Above the floor 25 there is a covering 26, which constitutes a finish of the passenger compartment 20 and in particular constitutes an exposed flooring of the passenger compartment 20.
Secondo quanto illustrato nella figura 2, il sistema 14 di accumulo comprende due dispositivi 15a di accumulo, i quali sono disposti da lati opposti di un asse longitudinale del veicolo 1 stradale (cioà ̈ da lati opposti del tunnel 24 centrale) e sono disposti di fronte a due sedili 27 anteriori. Inoltre, il sistema 14 di accumulo comprende quattro dispositivi 15b di accumulo, i quali sono disposti da lati opposti di un asse longitudinale del veicolo 1 stradale (cioà ̈ da lati opposti del tunnel 24 centrale) e sono disposti al di sotto dei due sedili 27 anteriori. Infine, il sistema 14 di accumulo comprende due dispositivi 15c di accumulo, i quali sono disposti da lati opposti di un asse longitudinale del veicolo 1 stradale (cioà ̈ da lati opposti del tunnel 24 centrale) e sono disposti di fronte a due sedili 28 posteriori (cioà ̈ dietro ai due sedili 27 anteriori). Ovviamente, in funzione delle caratteristiche del veicolo 1 stradale il numero e/o la disposizione dei sopra descritti dispositivi 15 di accumulo può variare; ad esempio potrebbero essere assenti i dispositivi 15c di accumulo, potrebbero essere previsti solo due dispositivi 15b di accumulo, oppure potrebbero essere previsti quattro dispositivi 15a di accumulo. As illustrated in Figure 2, the accumulation system 14 comprises two accumulation devices 15a, which are arranged on opposite sides of a longitudinal axis of the road vehicle 1 (i.e. on opposite sides of the central tunnel 24) and are arranged opposite with two 27 front seats. Furthermore, the accumulation system 14 comprises four accumulation devices 15b, which are arranged on opposite sides of a longitudinal axis of the road vehicle 1 (i.e. on opposite sides of the central tunnel 24) and are arranged under the two seats 27 anterior. Finally, the accumulation system 14 comprises two accumulation devices 15c, which are arranged on opposite sides of a longitudinal axis of the road vehicle 1 (i.e. on opposite sides of the central tunnel 24) and are arranged in front of two rear seats 28 (ie behind the two front seats 27). Obviously, depending on the characteristics of the road vehicle 1, the number and / or arrangement of the above described accumulation devices 15 can vary; for example the accumulation devices 15c could be absent, only two accumulation devices 15b could be provided, or four accumulation devices 15a could be provided.
Secondo quanto illustrato nelle figure 4 e 5, ciascun dispositivo 15 di accumulo à ̈ appoggiato al pianale 25 al di sotto del rivestimento 26 in modo da essere disposto tra il pianale 25 ed il rivestimento 26. Per ciascun dispositivo 15 di accumulo à ̈ previsto un elemento 29 di contenimento che à ̈ fissato al pianale 25 e definisce una sede 30, la quale riproduce in negativo la forma del dispositivo 15 di accumulo ed à ̈ atta ad alloggiare al proprio interno il dispositivo 15 di accumulo stesso. Una funzione di ciascun elemento 29 di contenimento à ̈ di fornire un adeguato supporto meccanico al dispositivo 15 di accumulo per dare al dispositivo 15 di accumulo una posizione stabile e quindi impedire movimenti indesiderati del dispositivo 15 di accumulo stesso; una ulteriore funzione di ciascun elemento 29 di contenimento à ̈ di riempire gli spazi vuoti attorno al dispositivo 15 di accumulo in modo da pareggiare il livello e fornire un piano uniforme e privo di scalini al rivestimento 26. According to what is illustrated in Figures 4 and 5, each accumulation device 15 rests on the platform 25 under the lining 26 so as to be arranged between the platform 25 and the lining 26. For each accumulation device 15 a containment element 29 which is fixed to the platform 25 and defines a seat 30, which reproduces in negative the shape of the storage device 15 and is able to house the storage device 15 itself inside. A function of each containment element 29 is to provide adequate mechanical support to the accumulation device 15 to give the accumulation device 15 a stable position and therefore to prevent unwanted movements of the accumulation device 15 itself; a further function of each containment element 29 is to fill the empty spaces around the accumulation device 15 so as to equalize the level and provide a uniform and step-free plane to the cladding 26.
Secondo una preferita forma di attuazione, ciascun dispositivo 15 di accumulo ha una forma all’incirca parallelepipeda e presenta una parete 31 di base riscaldante, la quale à ̈ normalmente orizzontale ed à ̈ priva di isolamento termico, ed una parete 32 di base nonriscaldante, la quale à ̈ normalmente orizzontale, à ̈ parallela ed opposta alla parete 31 di base riscaldante ed à ̈ provvista di uno strato 33 di materiale termicamente isolante. Secondo una prima forma di attuazione, la parete 32 di base non-riscaldante à ̈ sempre rivolta verso l’alto per essere a contatto del rivestimento 26 e la parete 31 di base riscaldante à ̈ sempre rivolta verso il basso per essere a contatto del pianale 25; in questo modo, il calore prodotto durante l’uso da ciascun dispositivo 15 di accumulo non entra nell’abitacolo 20 e viene sfogato verso il basso venendo trasmesso al pianale 25 che essendo costantemente lambito dall’aria à ̈ naturalmente raffreddato. Secondo una diversa forma di attuazione, ciascun dispositivo 15 di accumulo à ̈ realizzato con una simmetrica che permette il rovesciamento del dispositivo 15 di accumulo stesso in modo tale che la parete 31 di base riscaldante possa venire indifferentemente disposta a contatto del pianale 25 oppure a contatto del rivestimento 26; in questo modo, in funzione della stagione (estiva o invernale) à ̈ possibile scegliere se disporre la parete 31 di base riscaldante a contatto del pianale 25 per disperdere all’esterno il calore prodotto durante l’uso dal dispositivo 15 di accumulo (stagione estiva), oppure se disporre la parete 31 di base riscaldante a contatto del rivestimento 26 per convogliare il calore prodotto durante l’uso dal dispositivo 15 di accumulo all’interno dell’abitacolo 20 (stagione invernale). Questa forma di attuazione che prevede la reversibilità estate/inverno dei dispositivi 15 di accumulo massimizza l’efficienza energetica dei dispositivi 15 di accumulo permettendo, quando utile, il recupero del calore prodotto durante l’uso. According to a preferred embodiment, each storage device 15 has an approximately parallelepiped shape and has a heating base wall 31, which is normally horizontal and has no thermal insulation, and a non-heating base wall 32 , which is normally horizontal, is parallel and opposite to the heating base wall 31 and is provided with a layer 33 of thermally insulating material. According to a first embodiment, the non-heating base wall 32 is always turned upwards to be in contact with the cladding 26 and the heating base wall 31 is always turned downwards to be in contact with the floor 25; in this way, the heat produced during use by each storage device 15 does not enter the passenger compartment 20 and is vented downwards, being transmitted to the floor 25 which, being constantly lapped by the air, is naturally cooled. According to a different embodiment, each storage device 15 is made with a symmetrical one that allows the overturning of the storage device 15 itself so that the heating base wall 31 can be indifferently arranged in contact with the platform 25 or in contact of the coating 26; in this way, depending on the season (summer or winter), it is possible to choose whether to arrange the heating base wall 31 in contact with the platform 25 to disperse the heat produced during use by the storage device 15 outside ( summer season), or whether to arrange the heating base wall 31 in contact with the cladding 26 to convey the heat produced during use by the storage device 15 inside the passenger compartment 20 (winter season). This embodiment which provides for the summer / winter reversibility of the storage devices 15 maximizes the energy efficiency of the storage devices 15 allowing, when useful, the recovery of the heat produced during use.
Secondo una possibile forma di attuazione, due dispositivi 15 di accumulo disposti da lati opposti di un asse longitudinale del veicolo 1 stradale (cioà ̈ da lati opposti del tunnel 24 centrale) sono realizzati in modo tale che per rovesciare i dispositivi 15 di accumulo à ̈ necessario realizzare una inversione destra-sinistra dei dispositivi 15 di accumulo stessi; in altre parole, il dispositivo 15 di accumulo disposto a destra deve venire spostato a sinistra e viceversa. Questa forma di attuazione à ̈ indispensabile quando i dispositivi 15 di accumulo non hanno una base rettangolare che permette una elevata simmetria, ma hanno una base trapezoidale per seguire la forma del pianale 25. According to a possible embodiment, two accumulation devices 15 arranged on opposite sides of a longitudinal axis of the road vehicle 1 (i.e. on opposite sides of the central tunnel 24) are made in such a way that in order to overturn the accumulation devices 15, it is necessary to carry out a right-left inversion of the storage devices 15 themselves; in other words, the accumulation device 15 arranged on the right must be moved to the left and vice versa. This embodiment is indispensable when the storage devices 15 do not have a rectangular base which allows a high symmetry, but have a trapezoidal base to follow the shape of the platform 25.
Secondo una preferita forma di attuazione illustrata nella figura 6, per ciascun dispositivo 15 di accumulo à ̈ previsto un dispositivo 34 di collegamento, il quale presenta almeno due contatti 35 elettrici collegati all’azionamento 13 elettrico ed à ̈ disposto in posizione tale da disporre i propri contatti 35 elettrici affacciati ed interagenti con due contatti 36 elettrici del dispositivo 15 di accumulo. In particolare, ciascun dispositivo 15 di accumulo presenta le due pareti 31 e 32 di base tra loro parallele ed opposte e normalmente orizzontali e quattro pareti 37 laterali normalmente verticali; i secondi contatti 36 elettrici sono disposti in corrispondenza di una parete 37 laterale del dispositivo 15 di accumulo. Secondo una preferita forma di attuazione, i contatti 36 elettrici di ciascun dispositivo 15 di accumulo sono disposti in corrispondenza di una parete 37 laterale del dispositivo 15 di accumulo che à ̈ rivolta verso il tunnel 24 centrale; in questo modo, il dispositivo 34 di collegamento à ̈ integrato nel, appoggiato al, o comunque almeno prossimo al tunnel 24 centrale e quindi i cavi elettrici di collegamento (non illustrati) tra il dispositivo 34 di collegamento e l’azionamento 13 elettrico (disposto al retrotreno vicino alla macchina 8 elettrica reversibile) possono correre all’interno del tunnel 24 centrale. According to a preferred embodiment illustrated in Figure 6, a connection device 34 is provided for each storage device 15, which has at least two electrical contacts 35 connected to the electrical drive 13 and is arranged in such a position as to arrange its own electrical contacts 35 facing and interacting with two electrical contacts 36 of the storage device 15. In particular, each accumulation device 15 has the two base walls 31 and 32 parallel and opposite to each other and normally horizontal and four side walls 37 which are normally vertical; the second electrical contacts 36 are arranged in correspondence with a side wall 37 of the storage device 15. According to a preferred embodiment, the electrical contacts 36 of each storage device 15 are arranged in correspondence with a side wall 37 of the storage device 15 which faces the central tunnel 24; in this way, the connection device 34 is integrated into, supported by, or at least next to, the central tunnel 24 and therefore the electric connection cables (not shown) between the connection device 34 and the electric drive 13 ( arranged at the rear near the reversible electric machine 8) can run inside the central tunnel 24.
I contatti 35 elettrici di ciascun dispositivo 34 di collegamento sono montati mobili ed il dispositivo 34 di collegamento prevede elementi 38 elastici che spingono i contatti 35 elettrici verso l’esterno del dispositivo 34 di collegamento e contro i contatti 36 elettrici del dispositivo 15 di accumulo che sono fissi. Quando un dispositivo 15 di accumulo à ̈ inserito nella propria sede 30, i contatti 36 elettrici del dispositivo 15 di accumulo spingono all’indietro i contatti 35 elettrici del dispositivo 34 di collegamento comprimendo gli elementi 38 elastici; in questo modo, gli elementi 38 elastici spingono con una forza predeterminata i contatti 35 elettrici del dispositivo 34 di collegamento contro i contatti 36 elettrici del dispositivo 15 di accumulo riducendo la resistenza elettrica localizzata nel punto di contatto. The electrical contacts 35 of each connection device 34 are mounted movably and the connection device 34 has elastic elements 38 which push the electrical contacts 35 towards the outside of the connection device 34 and against the electrical contacts 36 of the storage device 15 which are fixed. When an accumulation device 15 is inserted in its seat 30, the electric contacts 36 of the accumulation device 15 push back the electric contacts 35 of the connection device 34 compressing the elastic elements 38; in this way, the elastic elements 38 push the electrical contacts 35 of the connection device 34 against the electrical contacts 36 of the storage device 15 with a predetermined force, reducing the electrical resistance located at the point of contact.
Secondo una possibile forma di attuazione illustrata nella figura 6, ciascun dispositivo 15 di accumulo comprende una paratia 39 montata mobile tra una posizione aperta, in cui permette l’accesso ai contatti 36 elettrici, ed una posizione chiusa che impedisce l’accesso ai contatti 36 elettrici; inoltre, ciascun dispositivo 15 di accumulo comprende un elemento 40 elastico che spinge la paratia 39 verso la posizione chiusa. Ciascuna sede 30 à ̈ conformata in modo tale da spingere la paratia 39 nella posizione aperta comprimendo l’elemento 40 elastico quando il dispositivo 15 di accumulo viene inserito all’interno della sede 30; invece, quando il dispositivo 15 di accumulo viene estratto dalla sede 30 la paratia 39 viene immediatamente ed automaticamente spinta nella posizione di chiusura dall’elemento 40 elastico. According to a possible embodiment illustrated in Figure 6, each storage device 15 comprises a bulkhead 39 mounted movable between an open position, in which it allows access to the electrical contacts 36, and a closed position that prevents access to the 36 electrical contacts; moreover, each accumulation device 15 comprises an elastic element 40 which pushes the bulkhead 39 towards the closed position. Each seat 30 is shaped in such a way as to push the bulkhead 39 into the open position by compressing the elastic element 40 when the storage device 15 is inserted inside the seat 30; on the other hand, when the storage device 15 is extracted from the seat 30, the bulkhead 39 is immediately and automatically pushed into the closed position by the elastic element 40.
Secondo una ulteriore forma di attuazione illustrata nella figura 6, ciascun dispositivo 15 di accumulo comprende un sezionatore 41 elettrico (cioà ̈ un dispositivo che à ̈ in grado di interrompere la continuità metallica dei conduttori di un circuito elettrico per garantire l’isolamento ai fini della sicurezza) che à ̈ disposto a monte dei contatti 36 elettrici ed isola elettricamente i contatti 36 elettrici quando il dispositivo 15 di accumulo non à ̈ accoppiato ai contatti 35 elettrici (cioà ̈ non à ̈ inserito all’interno della sede 30). Preferibilmente, ciascun dispositivo 15 di accumulo comprende un organo 42 di segnalazione visivo che à ̈ collegato (tipicamente meccanicamente) al sezionatore 41 elettrico ed indica visivamente lo stato di apertura o chiusura del sezionatore 41 elettrico stesso (ad esempio indica un colore verde quando il sezionatore 41 elettrico à ̈ aperto ed un colore rosso quando il sezionatore 41 elettrico à ̈ chiuso). Lo scopo dell’organo 42 di segnalazione à ̈ di segnalare quando il sezionatore 41 elettrico à ̈ aperto e quindi quando si può manipolare il dispositivo 15 di accumulo in sicurezza senza il rischio di folgorazioni elettriche toccano anche accidentalmente i contatti 36 elettrici. According to a further embodiment illustrated in Figure 6, each storage device 15 comprises an electrical disconnector 41 (i.e. a device which is capable of interrupting the metallic continuity of the conductors of an electrical circuit to ensure insulation for the purposes of safety) which is arranged upstream of the electrical contacts 36 and electrically isolates the electrical contacts 36 when the storage device 15 is not coupled to the electrical contacts 35 (that is, it is not inserted inside the seat 30). Preferably, each storage device 15 comprises a visual signaling member 42 which is connected (typically mechanically) to the electrical disconnector 41 and visually indicates the opening or closing state of the electrical disconnector 41 itself (for example it indicates a green color when the disconnector 41 electric is open and a red color when the electric 41 switch is closed). The purpose of the signaling organ 42 is to signal when the electrical disconnector 41 is open and therefore when the storage device 15 can be handled safely without the risk of electric shocks, even accidentally touching the electrical contacts 36.
Secondo una possibile forma di attuazione, ciascun sezionatore 41 elettrico à ̈ normalmente aperto ed à ̈ spinto e mantenuto nella posizione aperta da un elemento 43 elastico che deve venire compresso per mantenere il sezionatore 41 elettrico nella posizione chiusa; quindi senza una adeguata spinta che comprime l’elemento elastico il sezionatore 41 elettrico à ̈ aperto. Inoltre, secondo una possibile forma di attuazione, ciascun sezionatore 41 elettrico à ̈ accoppiato ad un dispositivo 44 di interblocco meccanico che permette la separazione dei contatti 36 elettrici del dispositivo 15 di accumulo dai contatti 35 elettrici del dispositivo 34 di collegamento (cioà ̈ l’estrazione del dispositivo 15 di accumulo dalla sede 30) solo quando il sezionatore 41 elettrico à ̈ aperto. A titolo di esempio, il dispositivo 44 di interblocco meccanico potrebbe prevedere almeno un perno (azionato manualmente o mediante un attuatore) che à ̈ portato mobile dal dispositivo 34 di collegamento e si inserisce all’interno di una corrispondente feritoia del dispositivo 15 di accumulo quando il dispositivo 15 di accumulo à ̈ disposto all’interno della sede 30 determinando con tale inserimento la chiusura del sezionatore 41 elettrico. According to a possible embodiment, each electrical disconnector 41 is normally open and is pushed and kept in the open position by an elastic element 43 which must be compressed to keep the electrical disconnector 41 in the closed position; therefore without an adequate thrust which compresses the elastic element, the electrical disconnector 41 is open. Furthermore, according to a possible embodiment, each electrical disconnector 41 is coupled to a mechanical interlocking device 44 which allows the separation of the electrical contacts 36 of the storage device 15 from the electrical contacts 35 of the connection device 34 (i.e. ™ extraction of the storage device 15 from its seat 30) only when the electrical disconnector 41 is open. By way of example, the mechanical interlocking device 44 could provide at least one pin (operated manually or by means of an actuator) which is carried mobile by the connection device 34 and is inserted inside a corresponding slot of the storage device 15 when the accumulation device 15 is arranged inside the seat 30, thus causing the closure of the electrical disconnector 41.
Gli accorgimenti di sicurezza sopra descritti (paratia 39 e sezionatore 41 elettrico) hanno la funzione di permettere una manipolazione degli accumulatori 15 di accumulo in sicurezza evitando rischi di folgorazione a seguito di un contatto accidentale con i contatti 36 elettrici dei dispositivi 15 di accumulo; in questo modo il sopra descritto rovesciamento dei dispositivi 15 di accumulo in funzione della stagione può venire seguito in sicurezza anche da un utente non esperto. Inoltre, gli accorgimenti di sicurezza sopra descritti (paratia 39 e sezionatore 41 elettrico) possono essere in alternativa oppure possono essere entrambi presenti. The safety measures described above (bulkhead 39 and electrical disconnector 41) have the function of allowing safe manipulation of the storage accumulators 15 avoiding the risk of electrocution following accidental contact with the electrical contacts 36 of the storage devices 15; in this way the above described overturning of the accumulation devices 15 according to the season can be safely followed even by an inexperienced user. Furthermore, the safety devices described above (bulkhead 39 and electrical disconnector 41) can be alternatively or both can be present.
Il veicolo 1 stradale sopra descritto presenta numerosi vantaggi, in quanto à ̈ di semplice ed economica realizzazione essendo strutturalmente molto simile ad un analogo veicolo stradale esistente e soprattutto offre una collocazione ottimale sotto tutti i punti di vista al sistema 14 di accumulo (cioà ̈ ai dispositivi 15 di accumulo). Innanzitutto, il sistema 14 di accumulo à ̈ estremamente protetto contro gli urti, in quanto à ̈ disposto all’interno della cellula di sicurezza dell’abitacolo 20. Nel veicolo 1 stradale sopra descritto, i dispositivi 34 di collegamento sono disposti in prossimità del tunnel 24 centrale, quindi i cavi elettrici di collegamento tra i dispositivi 34 di collegamento (cioà ̈ tra i dispositivi 15 di accumulo) e l’azionamento 13 elettrico possono correre all’interno del tunnel 24 centrale con un percorso privo di tortuosità , molto protetto e relativamente corto. The road vehicle 1 described above has numerous advantages, as it is simple and inexpensive to manufacture, being structurally very similar to a similar existing road vehicle and above all it offers an optimal location from all points of view to the accumulation system 14 (i.e. storage devices 15). First of all, the storage system 14 is extremely protected against impacts, as it is arranged inside the safety cell of the passenger compartment 20. In the road vehicle 1 described above, the connecting devices 34 are arranged close to of the central tunnel 24, therefore the electrical connection cables between the connection devices 34 (i.e. between the storage devices 15) and the electric drive 13 can run inside the central tunnel 24 with a path devoid of tortuosity , very protected and relatively short.
Nel veicolo 1 stradale il sistema 14 di accumulo à ̈ disposto in una posizione che non à ̈ soggetta a surriscaldamenti ed à ̈ facilmente raffreddabile (come detto in precedenza, il pianale 25 à ̈ costantemente lambito dall’aria durante la marcia del veicolo 1 stradale). In the road vehicle 1, the storage system 14 is arranged in a position that is not subject to overheating and can be easily cooled (as previously mentioned, the floor 25 is constantly lapped by the air while the vehicle 1 is running. road).
Infine, nel veicolo 1 stradale il sistema 14 di accumulo à ̈ disposto molto vicino al baricentro e molto vicino al terreno per non sbilanciare con la propria massa rilevante l’equilibrio del veicolo 1 stradale. Finally, in the road vehicle 1 the accumulation system 14 is arranged very close to the center of gravity and very close to the ground in order not to unbalance the balance of the road vehicle 1 with its relevant mass.
