Abstract

See full text

An actuator for opening and closing a door or a tailgate of a car contains a helical compression spring and a motor. The helical compression spring is provided for opening a door or the tailgate of a car when compressive forces of the helical compression spring are released. The motor is provided for compressing the helical compression spring in order to close the door or the tailgate of the car. The helical compression spring contains a helically coiled coated steel wire. The helically coiled coated steel wire contains a steel core and a metallic coating layer. The steel core contains a steel alloy. The steel alloy contains 0.8 to 0.95 wt % carbon, 0.2 to 0.9 wt % manganese; 0.1 to 1.4 wt % silicon; optionally one or more micro-alloying element. The microstructure of the steel core is drawn lamellar pearlite. The metallic coating layer contains at least 84% by mass of zinc.
