Braking device having a device spring

摘要

A braking device, for a motor vehicle brake system. The braking device has at least one movable activation element, at least one device for monitoring the position and movement of at least one activation element, and at least one compressible, electrically conductive device spring which is elastically prestressed between two abutments, wherein at least one of the abutments is of movable design, and the movement of the abutment is coupled at least partially to a movement of at least one activation element. The device spring is provided for moving at least one of the abutments into its unactivated release position. The invention proposes that the device spring be assigned a sensing function for monitoring the position and movement of at least one activation element. A degree of compression of the device spring can be sensed, and the device spring is arranged in an electrically insulated fashion between the two abutments.
