The detection device (1) engages with a selector rod (2) 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 (1) comprises a rotary sensor (3) provided with an activating member (4) and able to output a signal (S) correlated with the angular position ( beta ) of the activating member (4), and a motion conversion device (5) interposed between the activating member (4) and the selector rod (2) and able to convert the movements of both translation and rotation of the selector rod (2) into a rotation of the activating member (4). The motion conversion device (5) comprises a supporting part (8) fixed on the selector rod (2) and having a cam (9) defining a striker surface (P) extending along a portion of a helix, and a follower (7) fixed on the activating member (4) and having a contact portion (15a) able to slide along the aforesaid striker surface (P). <IMAGE> |
