DESCRIZIONE DESCRIPTION

“ Telaio motociclistico a geometria dinamicamente variabile”, "Motorcycle chassis with dynamically variable geometry",

L’invenzione di cui sopra, trova applicazione nel settore industriale che si occupa della realizzazione di motocicli, in particolare per uso sportivo. The aforementioned invention finds application in the industrial sector that deals with the manufacture of motorcycles, in particular for sports use.

Fino ad oggi, per quelle che sono le mie conoscenze personali, non esiste un telaio motociclistico, in grado di variare dinamicamente alcune dimensioni fondamentali per il proprio funzionamento, come ad esempio l'inclinazione del cannotto di sterzo. Up to now, according to my personal knowledge, there is no motorcycle frame capable of dynamically varying some fundamental dimensions for its operation, such as the inclination of the steering head.

Semplificando al massimo le cose, si può attribuire ad un telaio con minore angolazione del cannotto di sterzo, una moto più “agile” nell’affrontare percorsi lenti e tortuosi, ma sicuramente meno stabile sul veloce e viceversa. Simplifying things as much as possible, a frame with a lower angle of the steering head can be attributed to a bike that is more "agile" in dealing with slow and tortuous routes, but certainly less stable on the fast and vice versa.

Fino ad oggi quindi, i telai motociclistici “nascono” con un angolo di sterzo che possa essere un giusto compromesso tra una buona stabilità ed un’accettabile guidabilità della moto stessa. I telai più raffinati e sportivi offrono la possibilità di fare delle regolazioni in questo senso, ma sono regolazioni meccaniche da fare in officina a moto ferma; l inconveniente irrisolto di questi sistemi è che nell’utilizzo sportivo si potrebbe dover affrontare un tracciato dove si alternino curve velocissime ad altre molto lente; quindi anche la regolazione fatta nel box potrebbe essere solo un compromesso. Until now, therefore, motorcycle frames "are born" with a steering angle that can be a fair compromise between good stability and acceptable handling of the bike itself. The more refined and sporty frames offer the possibility of making adjustments in this sense, but they are mechanical adjustments to be made in the workshop with the bike stationary; the unresolved drawback of these systems is that in sports use you may have to tackle a track where very fast curves alternate with very slow ones; therefore even the adjustment made in the box could only be a compromise.

II vantaggio della mia invenzione è che questa variazione avviene dinamicamente, ovvero la regolazione deH’inclinazione del cannotto di sterzo varia in tempo reale in modo da affrontare ogni ingresso e percorrenza curva con l'inclinazione ideale per quel tipo di curva stessa, ossia a motocicletta in marcia. The advantage of my invention is that this variation takes place dynamically, i.e. the adjustment of the inclination of the steering head changes in real time in order to face each entry and curve with the ideal inclination for that type of curve, that is to say on a motorcycle. marching.

Il telaio motociclistico a geometria dinamicamente variabile, consiste in un particolare tipo di telaio, che non ha il cannotto di sterzo (indicato sul su disegno di pagina 2 con il n°1) solidale al resto della struttura, ma vincolato alle travi diagonali (indicate sul disegno di pagina 8 con il n°3), mediante un fulcro (indicato sul disegno di pagina 8 con il n° 2), e un regolatore (indicato sul disegno di pagina 8 con il n°4). The dynamically variable geometry motorcycle frame consists of a particular type of frame, which does not have the steering head (indicated on the drawing on page 2 with n ° 1) integral with the rest of the structure, but bound to the diagonal beams (indicated on the drawing on page 8 with n ° 3), by means of a fulcrum (indicated on the drawing on page 8 with n ° 2), and a regulator (indicated on the drawing on page 8 with n ° 4).

Grazie a questa innovazione, è possibile variare l’angolo di inclinazione del cannotto di sterzo, semplicemente variando la distanza dei punti a A e B indicati sul disegno di pagina 8 agendo sul regolatore. Thanks to this innovation, it is possible to vary the angle of inclination of the steering head simply by varying the distance of the points A and B indicated on the drawing on page 8 by acting on the regulator.

Il regolatore quindi, potrebbe essere sia un dispositivo di tipo meccanico, e quindi capace di regolare l’inclinazione del cannotto di sterzo se sollecitato meccanicamente in caso di frenata o di accelerazione o da altro; oppure un dispositivo meccatronico, ad esempio un servomotore o simile, capace di regolare l’inclinazione del cannotto di sterzo, essendo quindi gestito da un sistema elettronico, che per esempio, in funzione della velocità della moto, della inclinazione della stessa, del fato che si possa essere in accelerazione o i frenata, e di tutte le altre variabili di cui si voglia tener conto; possa determinare l’inclinazione ottimale del cannotto di sterzo, in ogni momento, per ottenere il massimo delle prestazioni dalla struttura. The regulator, therefore, could be either a mechanical device, and therefore capable of adjusting the inclination of the steering head if mechanically stressed in the event of braking or acceleration or otherwise; or a mechatronic device, for example a servomotor or the like, capable of adjusting the inclination of the steering head, being therefore managed by an electronic system, which for example, depending on the speed of the motorcycle, its inclination, the fate that you can be accelerating or braking, and all the other variables you want to take into account; can determine the optimal inclination of the steering head, at any time, to obtain maximum performance from the structure.

Il regolatore e tutti gli altri elementi citati possono essere sostituiti con dispositivi simili, ovvero il trovato può venire modificato mantenendo il concetto inventivo che ne è alla base, potendosi sostituire ogni dettaglio con altro equivalente. The regulator and all the other elements mentioned can be replaced with similar devices, ie the invention can be modified while maintaining the inventive concept underlying it, each detail being able to be replaced with another equivalent.

Claims (2)

RIVENDICAZIONI L’invenzione che si vuole rivendicare, consiste nel concetto di aver ideato un telaio motociclistico a geometria dinamicamente variabile, ovvero capace di modificare la propria geometria, e di conseguenza il proprio funzionamento, dinamicamente, ovvero nel momento stesso in cui sta funzionando. Ci sono stati esempi di telai che offrivano la possibilità di compiere regolazione deH’inclinazione del cannotto di sterzo, ma solo come regolazione meccanica da effettuare a moto ferma. CLAIMS The invention that we want to claim consists in the concept of having devised a motorcycle frame with dynamically variable geometry, that is, capable of changing its geometry, and consequently its functioning, dynamically, or at the very moment in which it is working. There have been examples of frames that offered the possibility of adjusting the inclination of the steering head, but only as a mechanical adjustment to be made when the bike is stationary. 2) L’invenzione che si vuole rivendicare, consiste nel concetto di aver ideato un telaio motociclistico a geometria dinamicamente variabile; e non il modo con cui si è raggiunto tale obiettivo. Si potrebbero infatti variare allo stesso modo altre quote significative di un telaio motociclistico (ad esempio il punto di attacco del forcellone posteriore mediante un dispositivo ad eccentrici, o la lunghezza dello stesso; oppure variare l'inclinazione del cannotto di sterzo con un dispositivo ad eccentrici); ma il concetto inventivo di base sarebbe il medesimo: cambiare la geometria della ciclistica mentre la moto è in2) The invention that we want to claim consists in the concept of having devised a motorcycle frame with dynamically variable geometry; and not the way in which this goal was achieved. In fact, other significant dimensions of a motorcycle frame could be varied in the same way (for example the attachment point of the rear swingarm by means of an eccentric device, or its length; or the inclination of the steering head could be varied with an eccentric device. ); but the basic inventive concept would be the same: change the geometry of the chassis while the bike is in
