FIELD: machine building.SUBSTANCE: device with controlled friction includes the first and the second elements (1, 2) mounted capable of movement relatively each other in direction of sliding, between which there are the first and the second friction elements (5, 5) symmetrically located with the possibility of selective friction on the second element. Pressure element (6) affects at each friction element by return force in direction of jamming position. The first friction element is capable of preventing relative movement of two elements in the first direction, and at the second direction - with the possibility of affecting both elements by opposite friction force depending upon stress created at the first wedged element by pressure element. The second friction element acts in opposite direction similar to the first friction element. The device additionally includes neutralisation means (10, 13, 14) of that friction element that can interlock relative movement of elements in one or the other direction providing the possibility to the other friction element create opposite friction force.EFFECT: movement with controlled friction in two directions.5 cl, 2 dwg |
