“SISTEMA DI PROPULSIONE FUORI BORDO PER UN VEICOLO PROVVISTO DI UN SISTEMA DI PROPULSIONE A BORDO, IN PARTICOLARE UN MOTORE A COMBUSTIONE INTERNA” "OUTBOARD PROPULSION SYSTEM FOR A VEHICLE EQUIPPED WITH AN ON-BOARD PROPULSION SYSTEM, IN PARTICULAR AN INTERNAL COMBUSTION ENGINE"

La presente invenzione è relativa ad un sistema di propulsione fuori bordo per un veicolo provvisto di un sistema di propulsione a bordo, in particolare un motore a combustione interna. The present invention relates to an outboard propulsion system for a vehicle provided with an on-board propulsion system, in particular an internal combustion engine.

Per limitare l’inquinamento ambientale prodotto all’interno delle aree urbane dalla circolazione di veicoli provvisti di motori a combustione interna, è noto realizzare un sistema di propulsione fuori bordo del tipo comprendente un carrello motorizzato, che viene inserito al disotto del veicolo, e viene azionato da un motore elettrico alimentato tramite una batteria ricaricabile. In order to limit the environmental pollution produced within urban areas by the circulation of vehicles equipped with internal combustion engines, it is known to provide an overboard propulsion system of the type comprising a motorized trolley, which is inserted under the vehicle, and is driven by an electric motor powered by a rechargeable battery.

Il carrello motorizzato è provvisto, inoltre, di un sistema di sollevamento per sollevare dal suolo le ruote di trazione di un assale del veicolo e consentire al sistema di propulsione fuori bordo di avanzare il veicolo attraverso le citate aree urbane. The motorized trolley is also provided with a lifting system to raise the drive wheels of a vehicle axle from the ground and allow the outboard propulsion system to move the vehicle through the aforementioned urban areas.

I sistemi di propulsione fuori bordo noti del tipo sopra descritto presentano alcuni inconvenienti principalmente discendenti dal fatto che il sistema di sollevamento del carrello motorizzato è relativamente complesso e costoso. Known outboard propulsion systems of the type described above have some drawbacks mainly due to the fact that the lifting system of the motorized trolley is relatively complex and expensive.

Scopo della presente invenzione è di realizzare un sistema di propulsione fuori bordo per un veicolo provvisto di un sistema di propulsione a bordo, in particolare un motore a combustione interna, che sia esente dagli inconvenienti sopra descritti e che sia di semplice ed economica attuazione. The object of the present invention is to provide an outboard propulsion system for a vehicle equipped with an on-board propulsion system, in particular an internal combustion engine, which is free from the drawbacks described above and which is simple and economical to implement.

Secondo la presente invenzione viene realizzato un sistema di propulsione fuori bordo per un veicolo provvisto di un sistema di propulsione a bordo, in particolare un motore a combustione interna, come rivendicato nelle rivendicazioni allegate. According to the present invention, an outboard propulsion system is provided for a vehicle provided with an onboard propulsion system, in particular an internal combustion engine, as claimed in the attached claims.

La presente invenzione verrà ora descritta con riferimento ai disegni annessi, che ne illustrano un esempio di attuazione non limitativo, in cui: The present invention will now be described with reference to the attached drawings, which illustrate a non-limiting example of embodiment, in which:

Figure 5 is similar to Figure 3 and schematically illustrates in section, with parts removed for clarity, a second variant of the detail of Figure 3.

Con riferimento alle figure 1, 2, e 3, con 1 è indicato, nel suo complesso, un sistema di propulsione fuori bordo per un veicolo 2 provvisto di un sistema di propulsione a bordo (non illustrato), in particolare un motore a combustione interna. With reference to Figures 1, 2, and 3, 1 indicates, as a whole, an outboard propulsion system for a vehicle 2 equipped with an on-board propulsion system (not shown), in particular an internal combustion engine .

Il veicolo 2 comprende un assale 3 anteriore ed un assale 4 posteriore montati per ruotare attorno a rispettivi assi 5 di rotazione sostanzialmente paralleli fra loro e ad una direzione 6 orizzontale. The vehicle 2 comprises a front axle 3 and a rear axle 4 mounted to rotate about respective axes 5 of rotation substantially parallel to each other and to a horizontal direction 6.

Ciascun assale 3, 4 supporta una coppia di ruote 7 comprendenti, ciascuna, un rispettivo cerchione 8 ed uno rispettivo pneumatico 9 montato sul cerchione 8 stesso. Each axle 3, 4 supports a pair of wheels 7 each comprising a respective rim 8 and a respective tire 9 mounted on the rim 8 itself.

Il sistema di propulsione 1 comprende un carrello 10 provvisto di un telaio 11 telescopico, il quale si estende nella direzione 6, e comprende, a sua volta, due barre 12 di supporto accoppiate in maniera scorrevole fra loro per spostarsi una rispetto all’altra nella direzione 6. The propulsion system 1 comprises a trolley 10 provided with a telescopic frame 11, which extends in the direction 6, and comprises, in turn, two support bars 12 slidably coupled to each other to move relative to each other in the direction 6.

Ciascuna barra 12 presenta una forma ad L, ed è provvista di una ruota 13 di avanzamento del carrello 10. Each bar 12 has an L-shape, and is provided with a wheel 13 for advancing the carriage 10.

Ciascuna barra 12 supporta, inoltre, un motore 14 elettrico provvisto di un albero 15 di uscita montato per ruotare attorno ad un asse 16 di rotazione parallelo alla direzione 6. Each bar 12 also supports an electric motor 14 provided with an output shaft 15 mounted to rotate around a rotation axis 16 parallel to direction 6.

Il sistema di propulsione 1 comprende, inoltre, un gruppo 17 di trasmissione per collegare fra loro l’assale 4 ed i motori 14. The propulsion system 1 also includes a transmission unit 17 to connect the axle 4 and the motors 14 together.

Il gruppo 17 comprende, per ciascun motore 14, un rispettivo albero 18 di trasmissione montato sulla relativa barra 12 per ruotare attorno ad un asse 19 di rotazione parallelo al relativo asse 16 ed una rispettiva trasmissione 20 a cinghia o catena per collegare fra loro il relativo albero 15 e l’albero 18 stesso. The unit 17 comprises, for each motor 14, a respective transmission shaft 18 mounted on the relative bar 12 to rotate around a rotation axis 19 parallel to the relative axis 16 and a respective belt or chain transmission 20 to connect the relative shaft 15 and shaft 18 itself.

Gli alberi 18 sono alberi a profilo scanalato, e definiscono parte di un dispositivo 21 a profilo scanalato comprendente, inoltre, per ciascun albero 18, un rispettivo mozzo 22 a profilo scanalato atto ad accoppiarsi con l’albero 18 stesso. The shafts 18 are splined profile shafts, and define part of a splined profile device 21 also comprising, for each shaft 18, a respective splined profile hub 22 suitable for coupling with the shaft 18 itself.

Il mozzo 22 comprende una piastra 23 di aggancio, la quale è disposta tra un relativo mozzo-ruota 24 dell’assale 4 ed il relativo cerchione 8, è montata trasversalmente al relativo asse 5, ed è provvista di un cannotto 25, che sporge dalla piastra 23 attraverso il cerchione 8 coassialmente all’asse 5 stesso. The hub 22 comprises a coupling plate 23, which is arranged between a relative wheel hub 24 of the axle 4 and the relative rim 8, is mounted transversely to the relative axis 5, and is provided with a sleeve 25, which protrudes from the plate 23 through the rim 8 coaxially to the axis 5 itself.

Il cerchione 8, la piastra 23, ed il mozzo-ruota 24 sono bloccati assialmente fra loro tramite una pluralità di viti 26 di serraggio montate parallelamente all’asse 5. The rim 8, the plate 23, and the wheel hub 24 are axially locked together by means of a plurality of tightening screws 26 mounted parallel to the axis 5.

Il funzionamento del sistema di propulsione 1 verrà ora descritto con riferimento alla figura 2 ed a partire da un istante in cui le barre 12 di supporto vengono spostate una rispetto all’altra nella direzione 6 in una posizione allargata, in cui il telaio 11 telescopico presenta una lunghezza maggiore di una larghezza del veicolo 2 (figura 2a). The operation of the propulsion system 1 will now be described with reference to Figure 2 and starting from an instant in which the support bars 12 are moved relative to each other in the direction 6 in an enlarged position, in which the telescopic frame 11 has a length greater than a width of the vehicle 2 (Figure 2a).

A questo punto, il veicolo 2 ed il carrello 10 vengono spostati uno rispetto all’altro in modo tale che l’asse 5 di rotazione dell’assale 4 posteriore coincida con gli assi 19 di rotazione degli alberi 18 di trasmissione (figura 2b). At this point, the vehicle 2 and the trolley 10 are moved relative to each other in such a way that the rotation axis 5 of the rear axle 4 coincides with the rotation axes 19 of the transmission shafts 18 (Figure 2b).

Infine, le barre 12 di supporto vengono spostate una rispetto all’altra nella direzione 6 in una posizione ristretta, in cui gli alberi 18 di trasmissione impegnano, e si accoppiano in maniera angolarmente fissa con, i relativi mozzi 22 (figura 2c). Finally, the support bars 12 are moved relative to each other in the direction 6 in a restricted position, in which the transmission shafts 18 engage, and are coupled in an angularly fixed manner with, the relative hubs 22 (Figure 2c).

La variante illustrata nella figura 4 differisce da quanto illustrato nelle figure 1-3 unicamente per il fatto che, in essa, ciascun albero 18 di trasmissione viene bloccato assialmente sul relativo mozzo 22 a profilo scanalato tramite una vite 27 di serraggio, la quale si estende attraverso l’albero 18 coassialmente all’asse 19, e viene avvitata nella piastra 23. The variant illustrated in Figure 4 differs from that illustrated in Figures 1-3 only in that, in it, each transmission shaft 18 is axially locked on the relative splined profile hub 22 by means of a tightening screw 27, which extends through the shaft 18 coaxially to the axis 19, and is screwed into the plate 23.

La variante illustrata nella figura 5 differisce da quanto illustrato nelle figure 1-4 unicamente per il fatto che, in essa, ciascun albero 18 di trasmissione viene bloccato assialmente sul relativo mozzo 22 a profilo scanalato tramite un dispositivo 28 di bloccaggio comprendente un’asta 29 di aggancio, la quale si estende all’interno di una cavità 30 ricavata nell’albero 18 parallelamente all’asse 19, sporge assialmente all’esterno della cavità 30, e presenta un dente 31 di aggancio ricavato su una estremità libera dell’asta 29 per accoppiarsi con una cava 32 ricavata sulla superficie interna del mozzo 22. The variant illustrated in Figure 5 differs from what is illustrated in Figures 1-4 only in that, in it, each transmission shaft 18 is axially locked on the relative splined profile hub 22 by means of a locking device 28 comprising a rod 29 which extends inside a cavity 30 obtained in the shaft 18 parallel to the axis 19, protrudes axially outside the cavity 30, and has a hooking tooth 31 obtained on a free end of the rod 29 to couple with a groove 32 obtained on the internal surface of the hub 22.

Il dente 31 viene spostato, e normalmente mantenuto, in una posizione di aggancio (figura 5), in cui il dente 31 impegna la cava 32, da una coppia di molle 33 alloggiate all’interno della cavità 30 ed interposte tra l’albero 18 e l’asta 29. The tooth 31 is moved, and normally maintained, in a hooking position (figure 5), in which the tooth 31 engages the slot 32, by a pair of springs 33 housed inside the cavity 30 and interposed between the shaft 18 and auction 29.

Il dente 31 viene spostato contro l’azione delle molle 33 dalla sua posizione di aggancio in una posizione di sgancio (non illustrata), in cui il dente 31 disimpegna la cava 32, o tramite l’azionamento di un pulsante 34 di sgancio ricavato sull’asta 29 e sporgente all’esterno dell’albero 18 o tramite l’azionamento di un cavo 35 di trazione, per esempio un cavo Bowden, collegato con l’asta 29 stessa. The tooth 31 is moved against the action of the springs 33 from its hooking position into a release position (not shown), in which the tooth 31 disengages the slot 32, or by operating a release button 34 obtained on the rod 29 protrudes outside the shaft 18 or through the actuation of a traction cable 35, for example a Bowden cable, connected to the rod 29 itself.

Secondo una variante non illustrata, le ruote 13 vengono eliminate ed il carrello 10 viene fissato ad un telaio del veicolo 2 tramite un dispositivo di fissaggio. According to a variant not shown, the wheels 13 are eliminated and the trolley 10 is fixed to a frame of the vehicle 2 by means of a fixing device.

Il dispositivo 21 a profilo scanalato consente di accoppiare in maniera relativamente semplice ed economica il carrello 10 con l’assale 4 e, quindi, i motori 14 elettrici direttamente con l’assale 4.
