UNICO CORPO DI SUPPORTO. SINGLE SUPPORT BODY.
DESCRIZIONE DESCRIPTION
Il presente brevetto è attinente ai dispositivi di cambio dei rapporti di velocità per cicli e/o motocicli o altri veicoli e in particolare alla cassetta pignoni This patent relates to gear change devices for cycles and / or motorcycles or other vehicles and in particular to the sprocket box.
inserita sul mozzo delle ruote posteriori o anteriori dei cicli e/o motocicli e/o altri veicoli. inserted on the hub of the rear or front wheels of cycles and / or motorcycles and / or other vehicles.
La cassetta pignoni, detta anche pacco pignoni (fig. 2), è l’elemento, di forma tronco conica, che fa variare il rapporto di trasmissione della bicicletta tramite un comando impartito dal conduttore del ciclo, per mezzo del cambio (deragliatore di catena) posteriore. The sprocket cassette, also known as the sprocket set (fig. 2), is the truncated cone-shaped element that changes the transmission ratio of the bicycle by means of a command given by the cycle conductor, by means of the rear derailleur (chain derailleur ) rear.
La cassetta pignoni è inserita nel mozzo della ruota (sull’apposito innesto scanalato) e gira assieme ad essa, pertanto la catena della bicicletta, muovendosi a comando del cambio posteriore in su o in giù, permette la variazione di velocità del ciclo. The sprocket cassette is inserted into the wheel hub (on the special grooved coupling) and rotates together with it, therefore the bicycle chain, moving up or down with the rear gearbox, allows the cycle speed to be varied.
È noto che le cassette pignoni esistenti sono composte da pignoni (elementi piatti con dei denti per poter inserire la maglia della catena) inseriti singolarmente sull’innesto scanalato del mozzo ruota (chiamato anche “ruota libera"), o da più gruppi di 2, 3, 4 o più pignoni assemblati assieme e indivisibili. It is known that the existing sprocket cassettes are composed of sprockets (flat elements with teeth to be able to insert the chain link) inserted individually on the grooved coupling of the wheel hub (also called "free wheel"), or by more groups of 2, 3, 4 or more sprockets assembled together and indivisible.
E noto anche che esistono cassette pignoni composte di un solo corpo unico con i pignoni costruiti assieme. It is also known that there are sprocket cassettes composed of a single single body with the sprockets built together.
La quantità di pignoni definisce il numero di rapporti. Usualmente una cassetta pignoni ne contiene 8-9-10 o al massimo 11. The amount of sprockets defines the number of gears. Usually a sprocket box contains 8-9-10 or at most 11.
Il presente brevetto è costituito da un elemento di supporto (fig.l particolare A e/o fig.3) che va inserito tramite la sagoma interna (fig.3 part.F) direttamente nell’innesto scanalato del mozzo ruota (detto anche “ruota libera"). This patent consists of a support element (fig.l detail A and / or fig.3) which is inserted through the internal shape (fig.3 part.F) directly into the grooved coupling of the wheel hub (also called " free wheel ").
Esso potrà contenere i pignoni (fig.l part.B) che saranno alloggiati negli It may contain the pinions (fig.l part.B) which will be housed in the
appositi spazi del supporto (fig.l part.C e fig.3 part.C). suitable spaces of the support (fig.l part.C and fig.3 part.C).
Compito principale del presente trovato è quello di poter utilizzare i pignoni con dentature diverse(fig.l part.B) per poter variare il rapporto di trasmissione utilizzando lo stesso supporto (fig.lpart.A). Inoltre si possono mantenere gli stessi pignoni e sostituire il supporto (fig.l part.A e fig.3) con numero di rapporti diverso e/o forme di innesto scanalato diverse (fig.3 part.F). The main aim of the present invention is that of being able to use the pinions with different toothings (fig.l part.B) in order to vary the transmission ratio using the same support (fig.lpart.A). Furthermore, it is possible to keep the same pinions and replace the support (fig.l part A and fig.3) with different number of ratios and / or different grooved coupling shapes (fig.3 part.F).
Vengono quindi inseriti i pignoni (fig.l part.B)nel supporto (fig.l part.A) che esso stesso verrà poi inserito nell’innesto scanalato del mozzo della ruota tramite la sagoma centrale (fig.3 part.F). The pinions are then inserted (fig.l part.B) into the support (fig.l part.A) which itself will then be inserted into the grooved coupling of the wheel hub through the central shape (fig.3 part.F).
L’inserimento dei singoli pignoni (fig.l part.B) sul supporto (fig.l part. A) forma la cassetta pignoni (fig. 2). The insertion of the individual sprockets (fig.l part B) on the support (fig.l part. A) forms the sprocket box (fig. 2).
Tra un pignone e l’altro la distanza è fatta dalla spaziatura già precostruita del supporto (fig.l part. C e/o fig. 3 part.C) ma sono altresì tenuti a distanza da una serie di spaziatori detti distanziali (fig.l part. D) assemblati assieme al pignone (fig.l part.B). I distanziali (fig.l part.D) sono dei particolari di forma cilindrica o di altre forme, che misurano alcuni millimetri e possono essere di qualsiasi materiale (esempio: plastica, alluminio, ferro, titanio etc..). Between one pinion and another the distance is made by the already pre-built spacing of the support (fig. 1 part. C and / or fig. 3 part C) but they are also kept at a distance by a series of spacers called spacers (fig. l part. D) assembled together with the pinion (fig. l part.B). The spacers (fig.l part.D) are cylindrical or other shaped details, which measure a few millimeters and can be of any material (example: plastic, aluminum, iron, titanium, etc.).
I distanziali (fig.l part.D), inserendosi tra un pignone e l’altro, fanno sì che la cassetta resti compatta nel suo insieme, questo perché quando viene bloccata dalla The spacers (fig.l part D), inserting between one pinion and the other, ensure that the cassette remains compact as a whole, this is because when it is blocked by
ghiera di chiusura (fig.1 part. E) nel mozzo della ruota, comprime tutti i pignoni, e permette di restare compatta e ferma nelle sedi precostruite del supporto (fig.1 part. A). Con questo brevetto i singoli pignoni (fig.l part.B) possono essere sostituiti singolarmente per motivi di usura o per motivi di rapportatura diversa. locking ring nut (fig.1 part. E) in the wheel hub, compresses all the pinions, and allows it to remain compact and firm in the pre-built seats of the support (fig.1 part. A). With this patent the single pinions (fig.l part.B) can be replaced individually for reasons of wear or for reasons of different ratios.
Infatti nelle stesse sedi del supporto (fig.l part. A) possono essere inseriti pignoni fig.l part. B) di diversa misura a seconda delle esigenze del rapporto di trasmissione. In fact, in the same seats of the support (fig.l part. A) pinions fig.l part. B) of different sizes according to the needs of the transmission ratio.
Con questo brevetto, mantenendo gli stessi pignoni (fig.l part.B) e cambiando il supporto (fig.l part. A) si può avere una cassetta pignoni con numero di rapporti diversi (anche 12 pignoni o più), oppure si può inserire su inserti scanalati diversi (di altre Marche e forme). With this patent, keeping the same sprockets (fig.l part.B) and changing the support (fig.l part. A) you can have a sprocket box with different number of ratios (even 12 sprockets or more), or you can insert on different grooved inserts (of other brands and shapes).
Pertanto con riferimento alla descrizione che precede e alle tavole accluse si esprimono le seguenti rivendicazioni. Therefore, with reference to the above description and the attached tables, the following claims are expressed.
