'ARRANGEMENT FOR THE INTERNAL CONTROL OF SELECTION OF A GEARBOX WITH SELECTION ACTUATOR, AND ASSOCIATED GEARBOX'

摘要

The present invention proposes an arrangement which includes a member (10) of control of the selection of a rotating and sliding axially, an elastic return means of the control member to a first angular position of the selection, an actuator controlled, which applies a control force to the control member in order to cause its rotation, from its first selection position towards a second angular position, against the return force, characterized in that it comprises a fixed radial finger (42) and a movable grill (40), carried by the control member (10), in which is received the finger is fixed and comprising a radial groove (rl) in which the finger moves in the two directions and at least one axial groove (al2) which is connected to one end of the radial groove and in which the fixed finger (42) is displaced in two directions, and in that an axial groove (al2) is delimited by an axial surface (54 - 2) against which the fixed finger (42) is in the angular support under the action of the resilient return means and in the absence of control force applied by the actuator.
