“AUTOMOBILE PROVVISTA DI UN CONDOTTO AERODINAMICO ANTERIORE†⠀ œCAR EQUIPPED WITH A FRONT AERODYNAMIC DUCTâ €

SETTORE DELLA TECNICA TECHNIQUE SECTOR

La presente invenzione à ̈ relativa ad una automobile provvista di un condotto aerodinamico anteriore. The present invention relates to an automobile provided with a front aerodynamic duct.

ARTE ANTERIORE ANTERIOR ART

Negli ultimi anni ha assunto sempre più importanza la cura aerodinamica delle automobili, sia per ridurre la resistenza aerodinamica, sia per aumentare la deportanza, ovvero per fare in modo che l’azione dell’aria (a velocità elevate) generi sulla automobile una spinta diretta verso il basso che aumenti la tenuta di strada. In recent years the aerodynamic care of automobiles has become increasingly important, both to reduce aerodynamic drag and to increase downforce, or to ensure that the action of air (at high speeds) generates a direct downward thrust that increases road holding.

In particolare, un componente critico per la resistenza aerodinamica à ̈ normalmente il parabrezza che, per inevitabili vincoli geometrici, presenta una inclinazione minore rispetto al cofano anteriore; ovvero in corrispondenza della giunzione tra cofano anteriore e parabrezza à ̈ presente una “discontinuità†nell’inclinazione della carrozzeria. Di conseguenza, in corrispondenza del parabrezza si generano turbolenze (ovvero disturbi) che hanno l’effetto di aumentare la resistenza aerodinamica. Attualmente, l’unica possibile soluzione a questo inconveniente à ̈ aumentare l’inclinazione del parabrezza, ma tale soluzione comporta normalmente una inaccettabile riduzione dell’altezza dell’abitacolo. In particular, a critical component for aerodynamic resistance is normally the windshield which, due to inevitable geometric constraints, has a lower inclination than the front bonnet; or in correspondence of the junction between the front bonnet and the windscreen there is a â € œdiscontinuityâ € in the inclination of the bodywork. Consequently, turbulence (ie disturbances) is generated in correspondence with the windscreen, which has the effect of increasing aerodynamic drag. Currently, the only possible solution to this problem is to increase the inclination of the windshield, but this solution usually involves an unacceptable reduction in the height of the passenger compartment.

DESCRIZIONE DELLA INVENZIONE DESCRIPTION OF THE INVENTION

Scopo della presente invenzione à ̈ di fornire una automobile provvista di un condotto aerodinamico anteriore, la quale automobile presenti una più bassa resistenza aerodinamica, presenti una maggiore deportanza e, nello stesso tempo, sia anche di facile ed economica realizzazione. The object of the present invention is to provide an automobile provided with a front aerodynamic duct, which automobile has a lower aerodynamic drag, has a greater downforce and, at the same time, is also easy and economical to manufacture.

Secondo la presente invenzione viene fornita una automobile provvista di un condotto aerodinamico anteriore, secondo quanto rivendicato dalle rivendicazioni allegate.

FORME DI ATTUAZIONE PREFERITE DELL’INVENZIONE PREFERRED FORMS OF IMPLEMENTATION OF THE INVENTION

Nella figura 1, con il numero 1 Ã ̈ indicata nel suo complesso una automobile a motore posteriore (o centrale) comprendente un telaio 2 (illustrato schematicamente nella figura 5), il quale supporta una coppia di ruote 3 anteriori ed una coppia di ruote 4 posteriori. In figure 1, the number 1 indicates as a whole a rear (or central) engine car comprising a frame 2 (schematically illustrated in figure 5), which supports a pair of front wheels 3 and a pair of wheels 4 rear.

Tra le ruote 3 anteriori e le ruote 4 posteriori à ̈ ricavato un abitacolo 5 a cui si accede attraverso una coppia di portiere 6; frontalmente l’abitacolo 5 à ̈ delimitato da un parabrezza 7. Between the 3 front wheels and the 4 rear wheels there is a passenger compartment 5 which is accessed through a pair of doors 6; frontally, the passenger compartment 5 is delimited by a windshield 7.

Il telaio 2 Ã ̈ rivestito da una carrozzeria 8 che comprende, tra le altre cose, un paraurti 9 anteriore ed un cofano 10 anteriore. Il cofano 10 anteriore si raccorda frontalmente con il paraurti 9 anteriore e si raccorda posteriormente con il parabrezza 7. Secondo quanto illustrato nella figura 5, tra il cofano 10 anteriore ed il parabrezza 7 Ã ̈ ricavato uno scalino 11 destinato ad alloggiare i tergicristallo del parabrezza 7. The chassis 2 is covered with a body 8 which includes, among other things, a front bumper 9 and a front hood 10. The front hood 10 is connected at the front with the front bumper 9 and is connected at the rear with the windscreen 7. As shown in figure 5, between the front hood 10 and the windscreen 7 there is a step 11 intended to house the windscreen wipers 7.

Secondo quanto illustrato nelle figure 3 e 5, l’automobile 1 comprende un comprendere un condotto 12 aerodinamico, il quale si estende tra una apertura 13 di ingresso ricavata attraverso il paraurti 9 anteriore ed una apertura 14 di uscita ricavata attraverso il cofano 10 anteriore e di fronte al parabrezza 7; il condotto 12 aerodinamico à ̈ completamente libero, ovvero al suo interno à ̈ completamente privo di elementi che possano interferire con (ovvero rallentare, disturbare) il passaggio dell’aria, per permettere un flusso di aria ad alta velocità. In altre parole, all’interno del condotto 12 aerodinamico non à ̈ disposto alcun elemento esterno che possa interferire con (ovvero rallentare, disturbare) il passaggio dell’aria per massimizzare la velocità dell’aria attraverso il condotto 12 aerodinamico stesso. According to what is illustrated in Figures 3 and 5, the automobile 1 comprises a comprising an aerodynamic duct 12, which extends between an inlet opening 13 obtained through the front bumper 9 and an outlet opening 14 obtained through the front hood 10 and in front of the windscreen 7; the aerodynamic duct 12 is completely free, ie inside it is completely free of elements that can interfere with (or slow down, disturb) the passage of air, to allow a flow of air at high speed. In other words, inside the aerodynamic duct 12 there is no external element that could interfere with (ie slow down, disturb) the passage of air to maximize the speed of the air through the aerodynamic duct 12 itself.

Secondo una preferita forma di attuazione, il condotto 12 aerodinamico à ̈ disposto tra le due ruote 3 anteriori, ovvero à ̈ compreso nello spazio delimitato lateralmente dalle due ruote 3 anteriori. According to a preferred embodiment, the aerodynamic duct 12 is arranged between the two front wheels 3, ie it is included in the space delimited laterally by the two front wheels 3.

Secondo quanto illustrato nella figura 5, l’apertura 14 di uscita del condotto 12 aerodinamico à ̈ disposta in prossimità del parabrezza 7, ovvero il condotto 12 aerodinamico sfocia attraverso l’apertura 14 di uscita in prossimità del parabrezza 7. Inoltre, una porzione finale del condotto 12 aerodinamico à ̈ sostanzialmente parallela al parabrezza 7 in modo tale che il flusso d’aria che fuoriesce dal condotto 12 aerodinamico assuma una direzione sostanzialmente parallela al parabrezza 7. As shown in Figure 5, the exit opening 14 of the aerodynamic duct 12 is located near the windscreen 7, that is, the aerodynamic duct 12 opens through the exit opening 14 near the windscreen 7. Furthermore, a final portion of the aerodynamic duct 12 is substantially parallel to the windshield 7 so that the flow of air exiting from the aerodynamic duct 12 assumes a direction substantially parallel to the windshield 7.

Secondo quanto illustrato nella figura 5, il telaio 2 comprende un corpo 15 anteriore disposto di fronte all’abitacolo 5, un corpo 16 centrale al cui interno à ̈ ricavato l’abitacolo 5, ed un corpo posteriore (non illustrato) che supporta un motore a combustione interna ed à ̈ disposto dietro all’abitacolo 5. Il corpo 15 anteriore del telaio 2 comprende dei puntoni collassabili (non illustrati) che sono disposti longitudinalmente ed una coppia di traverse 17 e 18 che sono disposte trasversalmente una sopra all’altra e collegano tra loro i puntoni collassabili. In particolare, Il corpo 15 anteriore del telaio 2 comprende una traversa 17 superiore ed una traversa 18 inferiore alle quali à ̈ fissato il paraurti 9 anteriore; il condotto 12 aerodinamico à ̈ disposto tra la traversa 17 superiore e la traversa 18 inferiore del corpo 15 anteriore del telaio 2, ovvero il condotto 12 aerodinamico passa attraverso lo spazio delimitato sopra e sotto dalle due traverse 17 e 18 del corpo 15 anteriore del telaio 2. As shown in figure 5, the frame 2 comprises a front body 15 arranged in front of the passenger compartment 5, a central body 16 inside which the passenger compartment 5 is obtained, and a rear body (not shown) which supports an internal combustion engine and is arranged behind the passenger compartment 5. The front body 15 of the frame 2 comprises collapsible struts (not shown) which are arranged longitudinally and a pair of cross members 17 and 18 which are arranged transversely one above the € ™ other and connect the collapsible struts together. In particular, the front body 15 of the frame 2 comprises an upper cross member 17 and a lower cross member 18 to which the front bumper 9 is fixed; the aerodynamic duct 12 is arranged between the upper cross member 17 and the lower cross member 18 of the front body 15 of the frame 2, i.e. the aerodynamic duct 12 passes through the space delimited above and below by the two crosspieces 17 and 18 of the front body 15 of the frame 2.

Secondo una possibile forma di attuazione illustrata schematicamente nella figura 4, l’automobile 1 potrebbe comprendere una coppia di radiatori 19, i quali sono disposti da lati opposti del condotto 12 aerodinamico (ovvero sono disposti di fianco al condotto 12 aerodinamico) e sono completamente indipendenti dal condotto 12 aerodinamico stesso; in altre parole, i radiatori 19 sono completamente esterni al condotto 12 aerodinamico e quindi non hanno alcun componente in comune con il condotto 12 aerodinamico stesso. Preferibilmente, ciascun radiatore 19 à ̈ disposto di fronte ad una corrispondente ruota 3 anteriore (ovvero nello spazio del frontale dell’automobile 1 che non à ̈ interessato dal condotto 12 aerodinamico). Preferibilmente, ciascun radiatore 19 à ̈ inserito all’interno di un corrispondente condotto di raffreddamento, il quale à ̈ disposto di fianco al condotto 12 aerodinamico ed à ̈ completamente indipendente dal condotto 12 aerodinamico stesso. In altre parole, ciascun condotto di raffreddamento à ̈ disposto di fronte ad una corrispondente ruota 3 anteriore, à ̈ disposto di fianco al condotto 12 aerodinamico, ed alloggia un corrispondente radiatore 19. According to a possible embodiment schematically illustrated in Figure 4, the automobile 1 could comprise a pair of radiators 19, which are arranged on opposite sides of the aerodynamic duct 12 (i.e. they are arranged alongside the aerodynamic duct 12) and are completely independent of the aerodynamic duct 12 itself; in other words, the radiators 19 are completely external to the aerodynamic duct 12 and therefore have no component in common with the aerodynamic duct 12 itself. Preferably, each radiator 19 is arranged in front of a corresponding front wheel 3 (ie in the space of the front of the car 1 which is not affected by the aerodynamic duct 12). Preferably, each radiator 19 is inserted inside a corresponding cooling duct, which is arranged alongside the aerodynamic duct 12 and is completely independent from the aerodynamic duct 12 itself. In other words, each cooling duct is arranged in front of a corresponding front wheel 3, is arranged alongside the aerodynamic duct 12, and houses a corresponding radiator 19.

Secondo quanto illustrato nella figura 5, l’automobile 1 comprende un fondo vettura 20 che delimita inferiormente l’automobile 1 (ovvero à ̈ la parte più bassa dell’automobile 1) ed à ̈ affacciato alla superficie stradale. According to what is illustrated in Figure 5, the car 1 comprises a car floor 20 which delimits the car 1 below (ie it is the lowest part of the car 1) and faces the road surface.

L’automobile 1 sopra descritta presenta numerosi vantaggi. The automobile 1 described above has numerous advantages.

In primo luogo, l’automobile 1 sopra descritta presenta una ottima efficienza aerodinamica, in quanto il rapporto tra la deportanza che viene generata e la resistenza aerodinamica à ̈ molto favorevole (cioà ̈ à ̈ molto elevato). L’elevata efficienza aerodinamica viene raggiunta grazie alla presenza del condotto 12 aerodinamico che permette di ridurre la resistenza aerodinamica; tale risultato viene raggiunto grazie ad una azione di “pulizia†dei flussi di aria in corrispondenza del parabrezza 7 che permette di evitare l’insorgenza di turbolenze (ovvero di disturbi). In altre parole, il condotto 12 aerodinamico “spara†un flusso di aria ad alta velocità verso il parabrezza 7 e parallelamente al parabrezza 7 stesso; in questo modo, si evita l’insorgenza di turbolenze (ovvero di disturbi) in corrispondenza del parabrezza 7 (come invece avviene normalmente in assenza del condotto 12 aerodinamico). Inoltre, il condotto 12 aerodinamico permette anche di aumentare la deportanza dell’automobile 1, in quanto il flusso d’aria che attraversa il condotto 12 aerodinamico genera sull’automobile 1 una spinta diretta verso il basso che schiaccia l’automobile 1 al suolo. In the first place, the automobile 1 described above has an excellent aerodynamic efficiency, as the ratio between the downforce that is generated and the aerodynamic drag is very favorable (that is, it is very high). The high aerodynamic efficiency is achieved thanks to the presence of the aerodynamic duct 12 which allows to reduce aerodynamic drag; this result is achieved thanks to a â € œcleaningâ € action of the air flows in correspondence with the windscreen 7 which avoids the onset of turbulence (or disturbances). In other words, the aerodynamic duct 12 “shoots” a flow of air at high speed towards the windscreen 7 and parallel to the windscreen 7 itself; in this way, the onset of turbulence (or disturbances) in correspondence with the windscreen 7 is avoided (as is normally the case in the absence of the aerodynamic duct 12). Furthermore, the aerodynamic duct 12 also allows you to increase the downforce of the car 1, as the flow of air passing through the aerodynamic duct 12 generates a direct downward thrust on the car 1 that crushes the car 1 on the ground.

Grazie al fatto che il motore a combustione interna à ̈ disposto in posizione posteriore/centrale, il condotto 12 aerodinamico à ̈ semplicemente realizzabile in quanto à ̈ compatibile con tutti i vincoli geometrici dell’automobile 1. Ovviamente il condotto 12 aerodinamico penalizza un eventuale bagagliaio anteriore, ma tale limitazione non à ̈ normalmente un problema in una automobile ad altissime prestazioni. Thanks to the fact that the internal combustion engine is arranged in a rear / central position, the aerodynamic duct 12 is simply achievable as it is compatible with all the geometric constraints of the car 1. Obviously the aerodynamic duct 12 penalizes any front trunk, but that limitation is not normally a problem in a very high-performance car.

Infine, l’automobile 1 sopra descritta à ̈ di facile ed economica realizzazione, in quanto la realizzazione del condotto 12 aerodinamico richiede l’utilizzo di pochi componenti di peso ridotto e di costo contenuto. Finally, the car 1 described above is easy and inexpensive to manufacture, since the realization of the aerodynamic duct 12 requires the use of few components of reduced weight and low cost.
