Abstract: A steering mechanism for steering angular deflections carried out on a vehicle's/carriage's pivoted steering travelling wheels (10a, 12a; 10b, 12b) positioned in a row at each side of the carriage (16). During turning, the mechanism allots to each of the pivoted, steerable travelling wheels (10a, 10b, 12a, 12b) a correct deflection differing from that of each of the other steerable wheels (parallelism may occur between pivoted, steerable wheels (10a, 10b, 12a, 12b) upon 90° turns). Each steerable wheel is assigned an upright shaft for turning around the axis thereof, the shaft carrying at least one non-circular motion-transferring disc (22a, 22b, 24a′, 24b′) which, according to the invention, have elliptical circumferential shape and have the form of chain wheels/belt pulleys, identical in pairs. The elliptical chain wheels/belt pulleys (22a, 22b, 24a′, 24b′) are motion-transferringly interconnected by endless drivable chains/belts (26, 28, 30).
