ABSTRACT:
The detection device engages with a selector rod able to move in axial translation and in angular rotation to select the row of the gear and engage/disengage the gear in a vehicle gearbox. The detection device comprises a rotary sensor provided with an activating member and able to output a signal correlated with the angular position of the activating member, and a motion conversion device interposed between the activating member and the selector rod and able to convert the movements of both translation and rotation of the selector rod into a rotation of the activating member. The motion conversion device comprises a supporting part fixed on the selector rod and having a cam defining a striker surface extending along a portion of a helix, and a follower fixed on the activating member and having a contact portion able to slide along the aforesaid striker surface.
