ARTICULATION LINKAGE OF VARIABLE STRUCTURE Russian patent published in 2018 - IPC F16H21/10 F16C3/28 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to machine building, particularly, to articulation linkages. Articulation linkage of the variable structure contains a crank (1) and a rocker arm (2) pivotally connected to the fixed post (5) and the connecting rod (8). All links consist of pivotally connected parts, on which steel coils with windings are put connected to the source of electrical signals. To each of the coils both ends tension and compression helical coiled springs are secured. Springs are tightly enclosing the sections of the links. At that, the springs are made of an alloy with a thermomechanical shape memory effect.

EFFECT: springs are triggered when the temperature reaches the threshold values and, accordingly, switching off from operation or vice versa, switching on of the preset, pivotally connected section of the corresponding link.
