Abstract

A steering control mechanism of a vehicle steering box connected to a steering wheel through a shaft and a coupling for coupling two generally shaft-shaped elements in such manner that a rotational force can be transferred from one element to the other whereby the cardioids of these elements can form different angles with each other, including an intermediate element to which two swivelling coupling elements are connected, each of which is connected to the shaft and each of which has two opposing parts located on both sides of the cardioid of the swivelling coupling element which are connected to, and rotate around the intermediate element so that the one swivelling coupling element can swivel in one plane and the other swivelling coupling element can swivel in a plane perpendicular to the first, with regard to the intermediate element, the intermediate element being generally an endless section or an annular part, and that the opposing parts of each swivelling coupling element are formed by two pivot pins located inside said annular intermediate element and projecting radially outward with regard to the cardioid of a pivot coupling element, each of the pivot coupling elements bein…
