The present application claims priority under 35 U.S.C. §119 to German patent application 10 2014 002 732.5, filed Mar. 3, 2014, the entire disclosure of which is herein expressly incorporated by reference.
FIGS. 5 a and 5 b each illustrate a cross-sectional illustration of a non-aligned and an aligned device.
As is most clearly apparent from FIGS. 5 a and 5 b, the first end of the first, lower housing part 1 lies in a fastening plane 35, which is perpendicular to the longitudinal axis 17, to be fastened to the carrier (not shown in greater detail). The second end 19 of the second, upper housing part 2 lies in a fastening plane 33. The fastening plane 33 is perpendicular to the longitudinal axis 17, as long as the second housing part 2 is located in a starting position in relation to the first housing part 1 (FIG. 5 a). In this position, the fastening plane 33 is not inclined or pivoted in relation to the fastening plane 35. In the scope of the present description, this is understood as “no alignment”. In contrast, if the second housing part 2 is pivoted in relation to the first housing part 1 (cf. FIG. 5 b), the fastening plane 33 is thus perpendicular to an inclination axis 32 and corresponds to an inclined plane 34. The angle 37 enclosed between the inclination axis 32 and the longitudinal axis 17 is the result of an actuation of the tilting device 36, to align the second housing part 2 in relation to the first housing part 1 in a defined manner (in the example, by 3°). The useful component is arranged on the fastening plane 33.
Threaded pins 8 a at the respective free end of a respective wire 6, 7, 16 are tightened with full torque. A respective middle threaded pin 8 m is tightened with half torque. The “inner” threaded pin 8 i, which is associated in each case with the other housing part, is only tightened hand-tight.
For the alignment of the second housing part 2 in relation to the first housing part 1, as is schematically shown in FIGS. 5 a and 5 b, the compression spring 10 which ensures a pre-tension is also required in addition to an actuation of at least one of the wires 6, 7, 16.
After the triggering of the release mechanism, the spring 10, which is pre-tensioned between the first and the second housing parts 1, 2, is activated, i.e., the spring 10 presses the housing parts 1, 2 away from one another against the force of the wires 6, 7, 16, whereby the gap identified with 22 results. This operating configuration is shown in the figures. Each of the wires 6, 7, 16 can now be controlled in its length via its specific resistance in the above-described power circuit.
a first housing part arranged on a first end of the device and configured for stationary arrangement on a space vehicle;
a second housing part arranged on a second end of the device and configured for connection to the component, wherein the first end and the second end of the device rest on opposite sides of the device with respect to a longitudinal axis; and
a tilting device, which mechanically connects the first and the second housing parts to one another and provides a defined alignment and holding of a relative position of the second housing part in relation to the first housing part,
wherein an actuator of the tilting device comprises a number of wires made of a shape-memory alloy, wherein a length of each of the number of wires is individually adjustable by a respective determination of a resistance of the respective wire, which is processed as a control variable in a control loop.
6. The device of claim 1, wherein the tilting device comprises
at least one spring configured to press the first and the second housing parts away from one another; or
a cone-socket connection element, which is configured to enable arbitrary pivoting of the second housing part in relation to the first housing part.
7. The device of claim 6, wherein the first and the second housing parts are connected to one another via a release mechanism, which, in a starting configuration, blocks relative movement of the first and the second housing parts and, in an operating configuration, allows relative movement of the first and the second housing parts.
8. The device of claim 7, wherein the first and the second housing parts are spaced apart from one another, at least in the operating configuration, via the tilting device.
9. The device of claim 7, wherein the number of wires is not tensioned in the starting configuration.
10. The device of claim 7, wherein, wherein, after triggering of the release mechanism, the at least one spring tensions the number of wires.
11. The device of claim 1, wherein the tilting device comprises a compression spring, which is pre-tensioned between the first and the second housing parts, and which is arranged centrally in the region of the longitudinal axis of the device.
12. The device of claim 11, wherein the tilting device comprises three wires arranged equidistantly on a circle about the longitudinal axis.
13. The device of claim 6, wherein the cone-socket connection element is arranged centrally in the region of the longitudinal axis of the device.
14. The device of claim 13, wherein the tilting device comprises two wires, wherein the two wires are arranged offset to one another by 90° on a circle about the longitudinal axis, and wherein each of the wires is associated with a spring, which is arranged opposite to the associated wire on a circle in relation to the longitudinal axis.
15. The device of claim 14, wherein the spring associated with a wire counteracts the wire located on the opposite side in a same lever ratio.
16. The device of claim 13, wherein the tilting device comprises four wires, which are distributed equidistantly on a circle about the longitudinal axis of the device.
17. The device of claim 16, wherein each two opposing wires, which operate antagonistically, are connected to one another in the same lever ratio as a lever via the centrally arranged cone-socket connection element.
