Electrically operated parking brake for vehicle, comprises transmission element designed in shape of flexible shaft

摘要

The unit is designed as a duo-servo drum brake with a floating spreading module (2) formed by a spindle and nut arrangement (8) acting on the brake shoes (3,4). The nut (6) is moved by a rotating screw element (1) driven by an electric device (15). A flexible shaft (17) is positioned between the electric drive (15) and the screw (1), serving as the torque transmission element and facilitating a separate positioning of the drive (15) and the screw (1).
