摘要

Electronic device for selecting and controlling the steering modes of vehicles, in particular industrial vehicles with four steering wheels, of the type used to align the front and rear of said vehicle wheel, blocking in position steering cylinder (24, 26 ) of at least one pair of wheels, said device comprising a electronic control unit (30) which receives signals (S3, S4) from at least one alignment sensor (36, 34) disposed in line with a piston (20 , 22) of at least one steering cylinder (24, 26) of the vehicle, provided with a magnetic stripe (32, 38), controlling said control unit (30) with electric signals a plurality of distributor means (28 28A, 28B, 28C, 40, 42), capable of switching from one of said steering modes to another when said alignment occurs characterized in that said control unit (30) comprises buttons (44) to switch from a fu ncionamiento of automatic operation type manual shaft alignment, wherein in said operation of automatic type, the electronic control unit (30) switches the logic level of the electric signals (S1, S2) to those signals type sensor alignment (S3, S4) whereas in said operations manual type, the logic level of the electric signals (S1, S2) are manually switched by actuating one of said push buttons (44) while ignores these signals alignment sensor (S3, S4).
