Abstract

A linear drive system has an actuator (10), which can be moved in a translatory manner by an electric drive (12) and which is coupled to a mechanical energy storage (16) in the form of a spring (32). In the event of a loss of energy at the electric drive (12) or in an emergency operation, the actuator (10) travels to a predeterminable position and in so doing exerts an actuating force. One free end of the spring (32) is supported at the free end of the spindle housing (20), and the other free end of the spring (32) is supported at a closing part (36) of the actuator (10) or at the actuator (10) itself and is tensioned in every travel position of the actuator (10).
