Blocking device for automatic gearbox of vehicle, has blocking mechanism comprising mobile core associated with movable blocking plate of gearbox actuation system, and detecting unit to locate position of core with respect to blocking plate

摘要

The device (1) has a blocking mechanism comprising a mobile core associated with a movable blocking plate (4) of a gearbox actuation system such that the core implies an actuation speed of a vehicle in one position and implies a rest condition of the vehicle in another position. The blocking mechanism includes a detecting unit to locate the position of the core with respect to the plate of the gearbox actuation system. The detecting unit includes a Hall sensor connected to a base plate (5) that controls the displacement of the core, and a magnet (7) coupled with the blocking mechanism.
