Patent ID: 8281903

Claim:
A braking device for vehicles comprising a body, a lever hinged at a hinge point on said body that can be operated by a user of the vehicle, a hydraulic cylinder having a cylindrical chamber integral with the body and meant to be connected to a hydraulic braking circuit of the vehicle, the cylinder comprising a piston sliding in the chamber and moving under the action of the said lever to control the braking action of the vehicle, characterised in that the lever acts on the piston to achieve the braking action by means of a cam mechanism, wherein the lever has a cam surface with a concave profile forming a groove along which a driven element slides during use, with said driven element being provided on a rod connected to the piston of the hydraulic cylinder to control the braking action; and the cam surface is shaped so that a push force exerted on the driven element by the cam is substantially parallel to the axis of the cylinder for each angular position of the lever.
