Abstract

An operating device for selecting gear ratios of a transmission. The operating device comprises a selector lever that is movable between at least three gear selection positions and a locking device for limiting the range of motion of the selector lever. The locking device has a cantilever assembly with a plurality of locking contours that are connected to the selector lever. Each locking contour is assigned to a selector lever position and can be engaged with locking element to form a motion stop for the selector lever. It is thus possible to implement even complex locking tasks in a structurally simple manner such that jams, that occur during actuation, or undefined operating states in the locking device can be prevented. The range of motion of the selector lever is largely freely controlled using an actuator control, and the device is relatively silent and has short shifting times.
