Hydraulic vehicle brake has parking brake device acting on brake piston and lockable in tensioned state by motor-driven threaded nut spindle assembly with sensor directly detecting tension force

摘要

The hydraulic vehicle brake has a parking brake device acting on the brake piston (10) and lockable in the tensioned state by a threaded nut spindle assembly (14,15) driven by an electric motor (4). A sensor is provided for directly detecting the tension force. The sensor is formed by a force sensor through which the spindle is supported on a housing of the electric motor. or is formed by a path sensor (26) detecting the movement of the spindle.
