1. An actuating apparatus for a motor vehicle brake, comprising:
a brake pedal,
a pressure supply device, driven by an electric motor drive,
a piston-cylinder unit, comprising a main cylinder and a piston, wherein the piston is movable within the main cylinder in a longitudinal direction, wherein the piston-cylinder unit is enabled to be actuated using the brake pedal, wherein the brake pedal is connected to the piston of the piston-cylinder unit,
a valve assembly including valves arranged to adjust brake pressures in a wheel-specific manner and to disconnect or connect the wheel brakes from or to the pressure supply device and the piston-cylinder unit,
an electronic control unit,
one or more sensor devices, respectively having one or more sensors or evaluation elements and a sensor target, configured to sense movement of one or more components of the actuating apparatus, wherein at least one of the one or more sensors or evaluation elements of the one or more sensor devices is disposed in the electronic control unit, on a system printed circuit board of the electronic control unit, and wherein the respective sensor targets of the one or more sensor devices are disposed inside or outside of the electronic control unit, wherein the respective sensor targets are mechanically and/or magnetically coupled with the at least one of the one or more sensors or evaluation elements disposed in the electronic control unit,
wherein movement of the brake pedal is mechanically transmitted to the electronic control unit via a first sensor actuating device including a first gear rack coupled to the brake pedal, wherein at least one first sensor target of the one or more sensor targets is actuated via a first gear wheel configured to convert translational motion of the first gear rack into rotational motion of at least one first shaft carrying the at least one first sensor target,
wherein movement of the piston is mechanically transmitted to the electronic control unit via a second sensor actuating device including a second gear rack coupled to the piston, wherein at least one second sensor target of the one or more sensor targets is actuated via a second gear wheel configured to convert translational motion of the second gear rack into rotational motion of at least one second shaft carrying the at least one second sensor target,
wherein the first and second gear racks extend parallel to the longitudinal direction of the piston-cylinder unit,
wherein the at least one first shaft and the at least one second shaft are disposed in a direction perpendicular to the longitudinal direction of the piston-cylinder unit, and
wherein the at least one first shaft and the at least one second shaft are mounted in bearing bushes.
