ABSTRACT:
An actuating device for a brake unit of a vehicle EBS includes a tappet positioned in a housing of the brake unit for actuating a piston to operate a brake valve. A displacement sensor slide measures axial movement of the tappet. So that moving parts of the actuating device are guided with minimal friction and that torque acting on the tappet is compensated for, the tappet includes a cylindrical attachment having a bottom with holes and a shell, a groove on the outer surface of the shell having openings, a spacer ring in the cylindrical attachment between the tappet and the piston having projections which extend into the holes, a guide ring in the groove having raised portions on its inner surface which extend into the openings and a window on its outer surface protruding through an opening into a slit on the housing to receive the displacement sensor slide.
