Abstract
A linear drive comprises: a lever having a through bore; a rod which extends through the bore; a bearing supporting the rod; a shape memory alloy connected to the lever and a first fixed bearing, the shape memory alloy exerting a tensile force on the lever when electrical power is applied; and a restoring element connected to the lever and a second fixed bearing, the restoring element exerting a restoring force on the lever and counter to the tensile force. In a first state, the lever is tilted making a non-positive connection between the lever and the rod. In a second state the lever is displaced in parallel to and in the direction of the tensile force. In a third state the lever is tilted back releasing the non-positive connection. In a fourth state, the lever is displaced in parallel to and in the direction of the restoring force.
