Abstract
A piston actuation device for the supply of a pressure medium in a pressure medium circuit of a brake system of a motor vehicle. A piston actuation device includes a piston actuable by a spindle drive to execute a back-and-forth translation movement in the direction of a piston guidance axis. The spindle drive has a spindle nut and a spindle that cooperates with the spindle nut via a screw drive. The screw drive converts a rotation movement of the spindle nut into a translation movement of the spindle in the direction of a spindle movement axis. To transmit the translation movement to the piston, the piston and the spindle are connected to each other in an axially fixed manner. The axially fixed connection between the piston and the spindle includes an articulated joint, which allows for a concentricity deviation between the piston guidance axis and the spindle movement axis.
