It is a reinforced pinion for moving mountable on the transmission shaft of the gearbox.

The analyzed technical problem concerns its secondary transmission of means using chain, crown and pinion to transmit movement from the motor shaft to the wheel, through secondary counterfeit.

A pignone crown system is a chain or gear transmission system, where the pinion is the smallest gear, while the crown is the larger gear.

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.

The analyzed technical problem concerns the wear of the transmission milleghe.

Mount Often, in fact, it occurs that the teeth of the Millerighe tree gradually is consumed by the toothing of the pinion which, slowly, for the continuous vibrations and friction, the affects and consumes it until it cancel it, sometimes completely interrupting the transmission and making it The vehicle unusable.

The gradual and inexorable wear makes the motorcycle unusable and the cost for replacing the transmission shaft is often such as not to be considered convenient.

Many bikes have been scrapped due to the lack of a comprehensive remedy and often treated a certain value of historical and collecting interest.

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;
  • Half-moon-shaped platelets (13), equipped with passers-by holes (9) that slip into passing excavations (2) of the circular extrusion (14) of the central pinion (3), up to be inserted with the inner edge (10 ) of the half-moon shape, outgoing each on the inner side (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-moon form, in contact with the upper internal edge (7) of the passing excavation (2) preventing interference from the central pinion (3) to escape from the Milleer tree (1) of transmission of a motorcycle change (19 ) - Table 1 Fig. 1, Table. 4 Fig. 4;
  • A plurality of screws (6) inserted in the holes (12) of the central pinion (3), crossing the passers-by holes (9) of the platelets (13) in the shape of a half moon that maintain all the 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.

Other features and advantages of the invention will be evident, to the reading of the following description, of an embodiment of the invention, provided by way of example, non-limiting, with the aid of the attached drawings illustrated in the attached tables. Anyone from the trade will be able to understand the invention.
