Hydro-mechanical force-transmission device

A force transmission and amplification device for a brake system comprising a pedal (1) and an output rod (2) for transmitting by way of the output rod (2) an output force (F2) having a higher intensity than an input force (F1) applied to pedal (1). An input rod (3) is secured to the pedal (1) for s...

More Information
Summary:A force transmission and amplification device for a brake system comprising a pedal (1) and an output rod (2) for transmitting by way of the output rod (2) an output force (F2) having a higher intensity than an input force (F1) applied to pedal (1). An input rod (3) is secured to the pedal (1) for supplying a primary piston (4) located in a first diameter (D1) of primary cylinder (5) to delimit a primary chamber (51) retaining a fluid. A second piston (6) secured to the output rod (2) is located in a second diameter (D2) of a second cylinder (7) to delimit a secondary chamber (71). The primary chamber (51) is connected to the secondary chamber (71) to immediately supply pressurized fluid which acts on the second piston (6) to develop the output force (F2).
