ABSTRACT:
A servo-assistance device (10) for a shift mechanism of a motor vehicle transmission, with which a characteristic curve can be produced which, as a function of a manual shifting force or a shift phase, has ranges of different gradients or proportionality to the manual shifting force. The servo-assistance device (10) includes an element (20) which is acted upon by the manual shifting force to be assisted. To produce the characteristic curve, the servo-assistance device (10) has components (42, 44, 50, 52) that are actuated by a servo-pressure (60) in such manner that the element (20) maintains its current position.
