<p>An automotive electric steering lock (1), wherein an electric motor (5), via a reduction assembly (6), a rotary/linear conversion assembly (11), and a sliding assembly (7), moves a push rod (8) between a forward position, in which it maintains a steering shaft (2) in an angularly fixed position, and a withdrawn position, in which it permits free rotation of the steering shaft (2). The reduction assembly (6) is defined by a single reduction unit, and the electric motor (5) is controlled to operate in one direction. The rotary/linear conversion assembly (11) is defined by cams (13) and corresponding cam followers (14), each cam (13) having a first portion (13a) with a gradually increasing lift, and a second portion (13b) with a lift decreasing more steeply than the first portion. And the sliding assembly (7) has a return spring (20) for pushing the push rod (8) into the withdrawn position. <IMAGE></p> |
