Red Cap Superpinion

Technical sheet and design tables

The pinion is a toothed wheel whose teeth are designed to hook a transmission chain, a belt or another perforated element or profile to another gear.

In the case of the motorcycle, we speak of pinion referring to the order connected to the gearbox output shaft, whether this is of the type of gears and the type with continuous variation, which is connected to the rear crown through a chain, but it is The use of a toothed belt is also possible.

The pinion is equipped with a central excavation with teeth that engages on the central part of the transmission shaft.

The shaft is equipped in the terminal part of a throat followed by a second teeth used to insert a closing platelet having snaped feet compared to the pinion teeth, which inserted in the initial part and rotated inside the throat and fixed By means of screws in the pinion, it prevents its leakage from the shaft itself.

Il problema tecnico analizzato riguarda proprio l’usura del millerighe della trasmissione.

Monto spesso, infatti, si verifica che la dentatura dell’albero millerighe gradualmente venga consumata dalla dentatura del pignone che, lentamente, per le continue vibrazioni e attriti, la intacca e la consuma fino ad annullarla, a volte del tutto interrompendone la trasmissione e rendendo inutilizzabile il mezzo.

L’usura, graduale ed inesorabile, rende la moto inutilizzabile ed il costo per la sostituzione dell’albero di trasmissione molto spesso è tale da non essere reputato conveniente.

Molte moto sono state rottamate per la mancanza di un rimedio esaustivo e spesso si è trattato di moto d’interesse storico e collezionistico di un certo valore.

To solve the aforementioned problem, KKBike International Srls has designed and created a reinforced pinion for bikes mountable on the transmission shaft of the gearbox, comprising:

A central sprocket (3), equipped with threaded holes (12) circumferentially arranged passers-by, equipped in the front of an extrusion (14) having on the sides, at the side surface, of passing excavations (2), and having an excavation Passante (4) equipped with circumferential socket (8) teeth (16) that migates with the central part (16), with the front front (18) and with the back (15) of the exit of a Milleer tree (1) of Transmission of change of a motorcycle (19) - TAV. 1 Fig. 1, Table 2 Fig. 2, Table 3 Fig. 3; of platelets (13) half-moon-shaped, equipped with passers-by holes (9) which They slip into the passing excavations (2) of the circular extrusion (14) of the central pinion (3), until it is inserted with the inner edge (10) of the half-moon shape, outgoing each on the inside (5) of the passing excavation ( 2), inside the mounting gorge (17) of the release of the MilleRighe tree (1) and with the upper side edge (11) of the half l shape One, in contact with the upper internal edge (7) of the passing excavation (2) preventing interference to the central pinion (3) to escape from the Milleer (1) shaft of transmission of a motorcycle (19) - TAV. 1 Fig. 1, Table 4 Fig. 4; a plurality of screws (6) inserted in the holes (12) of the central pinion (3), crossing the passing holes (9) of the platelets (13) in the shape of a half moon that maintain All solidarity elements between them - Tav. 1 Fig. 1, Table. 3 Fig. 3.

The pinion thus conceived, exploits all the useful teeth of the terminal part of the tree, making the coupling more solid than a normal sprocket that is taken only on the toothing of the central part (16) of the Milleghe tree (1) through very few components .

The central pinion (3), moreover, can also be mounted on a mineral tree (1) in which the central intake teeth (17) are worn or missing, transmitting the pair to the transmission shaft of the motorcycle (19) taking a grip On the rear teeth (15) and front (18) of the Milleghe tree (1) himself, without this having to be replaced.

The central pinion (3) is made of a less hard material of the Millerighe tree (1) for any torques to wear the Millerighe tree (1) more expensive to replace but wear the central pinion (3) - Table 1 fig. 1, Table 3 Fig. 3.

Altre caratteristiche e vantaggi dell’invenzione risulteranno evidenti, alla lettura della descrizione seguente, di una forma di realizzazione dell’invenzione, fornita a titolo esemplificativo, non limitativo, con l’ausilio dei disegni allegati illustrati nelle tavole allegate. Chiunque del mestiere potrà così meglio comprendere l’invenzione.
