Abstract

An articulated coupling, especially for rail vehicles, for transmitting the engine power from a hollow input shaft mounted on the vehicle frame, to an output shaft of limited movement surrounded by the hollow shaft has a first flange rigidly connected to the hollow shaft and a second flange rigidly connected to the output shaft. Two pairs of links connect the flanges. An overhung intermediate member surrounds the output shaft, with the links being supported on the intermediate member. To obtain optimum central symmetry; the two flanges are aligned, all the links are of equal length and so positioned relatively to one another that the projections of the articulation points in a plane extending perpendicularly to the output shaft form the corners of a square. The two opposite links on the intermediate member are pivotally supported at their center. These two links form an obtuse angle facing in the direction of the output shaft. The articulation points of the intermediate member lie on a circular line extending through the corners of the square. Rubber-metal joints are used at all pivotal joints so that the joints are of limited elasticity and can thus absorb angular shifts.
