Contact point for braking assistance servomotor

摘要

The device (4) has an axially movable cylinder (40), whose displacement is controlled by a control rod, where the device is located between a reaction disk and the rod. A sensor piston (5) is moved axially in the cylinder. A spring (44) pushes the sensor piston towards the front and includes a front face maintained in a plane same as that of a front face of the movable cylinder. The disk is placed between the control rod and a push rod. The push rod receives axial displacement efforts of the piston and a distributor-plunger and retransmits the efforts to a master brake cylinder.
