Patent

CA 2556984

A lever assembly (14) and a master cylinder (12) are provided. The lever assembly (14) includes a lever (16) and an adjuster mechanism that changes the mechanical advantage of the lever (16). The reach of the lever (16) relative to a handlebar can be adjusted. Both the mechanical advantage and reach of the lever (16) can be adjusted without tools and while a vehicle including the same is operated. The master cylinder (12) includes a reservoir (50) in a clamp area. A reservoir bladder (52) fits into the reservoir (50). A cover encloses the bladder (52) and includes a vent opening making the bladder at atmospheric pressure such that air can move into the bladder (52) and out of the bladder (52). The master cylinder (12) can be bled without reorienting the master cylinder (12). A method of adjusting a mechanical advantage of a lever (16) and a method of bleeding a braking system without reorienting the master cylinder (12) are also provided.

L'invention concerne un ensemble levier et un maître-cylindre. L'ensemble levier comprend un levier et un mécanisme d'ajustement permettant de modifier l'effet mécanique du levier. La portée du levier par rapport à un guidon peut être ajustée. L'effet mécanique et la portée du levier peuvent être ajustés sans outils et pendant le fonctionnement d'un véhicule comprenant ce dernier. Le maître-cylindre comprend un réservoir dans une zone de serrage. Une vessie de réservoir vient se loger dans le réservoir. Une enveloppe entoure cette vessie et comporte une ouverture de ventilation permettant de soumettre la vessie à la pression atmosphérique de sorte que de l'air puisse entrer dans la vessie et en sortir. Le maître-cylindre peut être purgé sans réorientation de ce dernier. L'invention concerne également un procédé destiné à ajuster un effet mécanique d'un levier ainsi qu'un procédé destiné à purger un système de freinage sans réorientation du maître-cylindre.
