Abstract

A stabilizer is provided for a motor vehicle with two shafts (2, 3), which extend in the transverse direction of the vehicle, can be coupled with one another via a mechanical coupling (40) and are in functional connection with wheels of the motor vehicle with their ends facing away from the coupling (40). A first shaft is connected to a first coupling portion designed as a locking disk and a second shaft is connected to a second coupling portion, which cooperates with the locking disk (7) and is designed as a locking device (8). The locking device (8) has a ratchet element (12A, 12B), which can be actuated by a cam disk (11) that can be rotatingly driven by a drive source (15) against a spring means, and a blocking member (13A, 13B) connected thereto, via which the shafts are connected in such a way that they rotate in unison in a first end position of the cam disk (11) because of a positive connection between the locking disk and the blocking member (12A, 12B), and the positive connection is abolished in a second end position of the cam disk (11). The ratchet element (12A, 12B) is designed according to the present invention with two lever arms (12A—1, 12A—2, 12B-1, 12B—2), which a…
