TECHNICAL FIELD

The present disclosure relates to field of two wheelers vehicle. Particularly, the present disclosure relates to an adjustable handlebar lever assembly for two wheelers. Further, the present disclosure relates construction and mechanism of the adjustable handlebar lever assembly.

BACKGROUND OF DISCLOSURE

The information in this section merely provides background information related to the present disclosure and may not constitute prior art(s).
Generally, most two-wheeled, three wheeled and four wheeled automobiles are equipped with a lever for operating the clutch with the purpose of engaging and disengaging the driver and driven shafts. The lever is also used to apply breaks for stopping or slowing down the motion of vehicle. The lever is mounted on the handlebar of the automobile, to be operated with the hand of the use. The existing lever comprises an integrated cam (200) and cam lever (300) for adjusting the mechanism of clutch and breaks, according to the grip size of the user. The integrated cam (200) of the existing lever is made of the steel and having a flat profile. The flat profile integrated cam (200) is engaged with the cam lever (300) while lever is operated by the user as shown in the figure 1. In the existing lever, some numbers (400) are engraved on the upper surface of the integrated cam to indicate the various adjusting positions in accordance with the grip of the user as shown in the figure 2(a).
A major drawback associated with the lever is that the steel integrated cam is manufactured by machining process that increases the production cost of the lever. The steel is an expensive material that increases the cost of the product for bulk production. Another drawback is that the edges of the flat profile integrated cam are easily wear out after a prolonged use and do not engage exactly with the cam
2

are easily wear out after a prolonged use and do not engage exactly with the cam lever (300) at desired adjustment. The numbers (400) engraved on the upper surface of the integrated cam (200) and knurling edges trap dust and moisture and become rusty after a long use. This reduces the operating life of the lever. The integrated cam (200) of the existing lever has small area (500) to hold and rotate which causes inconvenience for the user while adjusting the lever as shown in figure 2(b). The integrated cam (200) and adjustable lever are assembled by spinning process which demands more precision, consumes more time and accurate pressure to avoid the loosen and jamming of integrated cam (200).
Accordingly, there is immense need in the art to provide an improved lever that overcomes one or more existing limitations of the existing lever.
