The invention relates to a device for adjusting the camber and / or toe of the wheels (20) of wheel suspensions (10), especially for motor vehicles, comprising a wheel carrier (12) on which the respective wheel (20) is rotatably mounted and which is divided into a carrier part (24) receiving the wheel, a guiding part (22) connected to the wheel suspension (10), and two rotary parts, especially actuating cylinders (26, 28), arranged between the carrier part and the guiding part and rotatable in relation to each other, to the carrier part (24) and to the guiding part (22) about a common rotational axis (32). Each of said rotary parts can be moved by a drive (40) and an actuator (42) in both directions of rotation. According to the invention, the actuator (42) is designed for at least one of the rotary parts (26, 28) as a planetary gearbox (42), and the planetary gearbox (42) is especially radially externally arranged around the rotary part (26, 28).
