Drive device and method for controlling the drive device for the generation of an actuation movement
First Claim
1. Drive device for the generation of an actuation movement, having at least one actuation element made from a memory shape alloy, having at least one resetting element which counteracts the actuation movement of the at least one actuation element, the at least one actuation element is received between two connection elements that are arranged separately from each other and with spacing apart from each other and engages with or is fastened to each connection element, each connection element comprises a connection section as a receiver for the resetting element and comprises an installation section opposite to the connection section, the connection elements are held at a distance by the at least one actuation element and the at least one resetting element, which are positioned between connection sections of the connection elements, and, as a result of the opposing directions of action thereof, the connection elements are positioned in a defined starting position for controlling an actuation movement, the actuation element is held with a clamping element in a through bore of the connection element or is at least simply redirected, wherein the at least one actuation element and the at least one resetting element are positioned coaxially relative to each other and each engage with the connection elements, and the connection elements, the at least one actuation element and the at least one resetting element are formed as an assembly.

Abstract
Drive device and a method for controlling the drive device so as to produce an actuation movement. The drive device includes at least one actuation element (25) consisting of a shape memory alloy, and at least one return actuation element (21) which counteracts the actuation movement of the at least one actuation element (25), the at least one actuation element (25) being received between two connection elements (17) that are separated from, and associated with, one another, and engaging with or being secured to each connection element (17), the connection elements (17) being kept at a distance from one another by the at least one actuation element (25) and the at least one return actuation element (21) positioned between them (17) and, as a result of the opposing directions of action thereof, the connection elements (17) being positioned in a defined initial length for controlling an actuation movement.
