The invention concerns a movement transmission unit and a movement transmission apparatus employing the same. The movement transmission transmits at least two movement components, each possessing one degree of freedom of movement, from an input-side (6) to an output-side (82, 84), which movement then has at least two coupled degrees of freedom of movement, or vice versa. The invention also concerns one transmission unit (2) per input-side (6) degree of freedom of movement, i.e multiple transmission units (2), which are functionally bound together in parallel by means of their respective output sections (8). Each transmission unit (2) possesses an immobile, solidly fixed first section (4). Its input facility is a second section (6), which is bend linked to the fixed first section (4) by means of a unified linkage structure encompassing parts (22, 26, 34; 28, 36) and forming what becomes known as a first “parallelogram linkage”. This is movably linked in the direction of the corresponding degrees of freedom of movement of the transmission unit (2). The second section (6) is so designed, that by means of a second linkage structure, (46, 50, 58, 48, 52, 60), i.e. another “parallelogram linkage”, second section 6 allows output-side, free movement along the degree of freedom of movement of the other transmission units (2). For the increase of the movement precision of such a movement transmission apparatus, the first (22, 26, 34; 24, 28, 36) and/or the second (46, 50, 58; 48, 52, 60) linkage structures are designed as bend linkages. Further, the second section (6), the second linkage, (50; 52; 58; 60) and the output-side (8) are so designed, that the associated transmission unit (2) forms a rigid structure.
A movement transmission apparatus for the transmission of at least two input-side (6) movement components with respectively one degree of freedom of movement in an output-side (82, 84) movement with at least two degrees of freedom of movement, or vice versa, comprising a plurality of transmission units (2), each of the transmission units (2) corresponding to an input side (6) degree of freedom of movement, whereby the transmission units (2) ,whereby these transmission units (2), by means of their respective output sections (8) are coupled with one another in a functional and parallel manner, each transmission unit (2) includes a stationarily fixed first section (4) and as input section, a second section (6) which is connected thereto by a first linkage means (22, 26, 34;
A movement transmission apparatus for the transmission of three entry side movement components with respectively one degree of freedom of movement into an output-side movement with three degrees of freedom of movement, or vice versa, which comprises three transmission units (2′) with respectively one input section (6) and one output section (8), which, by means of their output sections (8) are coupled with one another in a functional, serial and parallel way, each transmission unit (2′) embraces an extension direction from its respective input section (6′) to its respective output section (8) and includes linkages constructed as bend linkages (50, 52, 58, 60) of such a kind, that its respective output section (8) allows free movement perpendicular to its extension direction, whereby the input section (6′) of the transmission unit (2′) is so designed, that the respective input-side movement is introduced into an angle to the extension direction, therein characterized, in that the bend linkages (50, 52, 58, 60) are designed according to a parallelogram swing linkage, whereby each parallelogram swing linkage includes a bar pair (46, 48) with respectively one bend linkage (50, 52, 58, 60) on all four bar ends and the two ends, respectively of one bar, (46;
