ABSTRACT:
Modifications in the steering wheel locking and unlocking means in cars and trucks include a cylindrical body (3) which houses the steering shaft (1) with the possibility of axial displacement, and is fitted with upper and lower flanges (4) and (5) respectively, forming a spool, between which there is an eccentric cam (9) solidly joined to the shaft of the ignition and starter key switch, with the upper flange (4) having some ascending rods (11) in two diametrically opposed points, which cross a block (12) solidly joined to the steering wheel (10), and which are fitted to a locking spider (14) which engages with an internal block (20) solidly joined to the steering shaft (1) so as to be housed within some radial notches (24) of the internal block, for solidly joining the steering wheel to the steering shaft and, the spider (14) being engagable, through elevation, within some other radial notches (26) made in an upper plug (28) screwed to the external block (12).
