DISPOSITIF DE VERROUILLAGE MOTORISE POUR VEHICULE AUTOMOBILE COMPORTANT DES MOYENS PERFECTIONNES DE LIMITATION DE LA COURSE DU PENE

摘要

The device is based on a bolt (12) controlled by a slider (26) on a partially threaded extension (22) of the output shaft (20) of an electric motor (18), which has an unthreaded section (56) of smaller diameter. When the motor is energised, the tip (14) of the bolt enters one of a number of slots (15) in the shaft (16) of the steering column. The bolt is locked in a position where the end (54) of a plate (34) abuts against the underside (52) of the slider, and a spring (53) around the extension is fully compressed. The slider moves towards the unthreaded section until its own thread departs from that of the threaded section (24).
