A control device (1) for a gear change of a vehicle comprising a support structure, a control member (3) borne by the support structure such that it can move in translation along a first axis (A) and rotate about this axis in order to carry out a manoeuvre to select the row of gears and a manoeuvre to engage or disengage these gears, an actuator (4) cooperating with the control member (3) in order to rotate it about the first axis (A) and dispose it, for each row of gears, in a neutral position and two engagement positions of respective gears, and a cam and tappet unit (6) interposed between the support structure and the control member (3) which can be selectively actuated in order axially to displace the control member (3) by a predetermined amount during the actuation of the actuator (4); the cam and tappet unit (6) comprises a tappet member (15) borne by the support structure and a guide member (16) rigid with the control member (3) and provided with a series of cams (17) parallel to one another and each adapted to be selectively engaged by the tappet member (15) in order to guide the displacement of the control member (3) between adjacent engagement positions of adjacent rows during the actuation of the actuator (4). <IMAGE> |
