IT1235196B - A brake, to the activation of which the kinetic energy of the means of locomotion contributes - Google Patents

Abstract

The invention is a brake applicable to any wheeled vehicle. This is characterized by the fact that both the muscular effort of the driver and the kinetic energy of the vehicle contribute to its operation. A good example is the drum brake in figure 1 (table 1), characterized by the fact that the action lever "6" includes a pair of pliers "1" which, if activated, acts on the circular crown "9" affixed to the drum "10" in figure 2. At the moment when the driver operates the brake control lever, the interlocked pair of pliers "1", being activated, becomes engaged via friction with the circular crown "9"; an angular movement follows which is concentrated on the fulcrum of lever "6", hence activation of the drum brake. In other words the inventive principle comes into play at the moment when the actual operative lever of any traditional mechanical disc or drum brake, as well as being engaged by the driver's effort, is also activated by that applied to it due to the effect of the movement of any mobile mechanical pair of pliers activated by the driver and acting on a suitable circular crown fixed to the wheel, (there can also be concomitant application of the said forces on the above mentioned operating lever). In the light of the above the invention has characteristics such as to be able to be considered a power brake; from the example just given, it is to be assumed that compared to a traditional drum brake, the driver can, with the same braking effect, operate the actual brake pedal or hand-brake with less muscular effort.
