Immobiliser for vehicle with automatic transmission

摘要

The lock has a cylinder (6) which turns in a housing from the initial position into the working one. In the working position, a bolt (32) is released via a mechanism such as a Bowden cable (4). The sleeve (7), turning with the cylinder, is enclosed by a control ring (9), to which it is coupled by a tongue working in a spiral groove, causing the ring to slide in the axial direction. A dog (13) on the outside of the ring engages in a slide (21) acting on the mechanism against spring action (20), so as to release the bolt. A locking lug (19) can be provided on the outside of the sleeve, acting on the slide before return to the initial position. With the slide in this position, the lug swings past it.
