Abstract
A braking device for a hydraulic motor vehicle braking system having an electromechanically driven booster stage and a ball screw drive. In order to provide a braking device which is of particularly compact, cost-effective and weight-saving construction and has short pedal strokes, and an easily adjustable pedal characteristic curve, at the same time enabling effective direct action in case of failure of the booster stage and comfortable haptic feedback at the pedal during normal operation, the actuating force from a piston rod is introduced into the spindle, wherein the piston rod can be moved axially to a limited extent relative to the spindle and a spring element is inserted in the flow of force of the actuating force between the piston rod and the spindle, which spring is compressed axially when the actuating force is introduced.
