Abstract
An electromechanical brake assist system driven by an electric motor cooperating with a master cylinder and having, along the axis of actuation, a helper piston in the shape of an axial sleeve solidly connected with a guide bracket and having a threaded surface. A nut, fixed in translation but free to rotate, has interior threads that complement those of the helper piston, which it receives, and exterior teeth that cooperate with the drive motor. A plunger piston carries a drive base so it can be pushed by the piston. Its other extremity is connected to the control rod, formed from a body and a head. The body has a crimping area and the head has a sleeve with an extremity that can be crimped along the crimping area.
