Embodiment Construction

[0031] In the ensuing description as well as in the figures, in order to avoid repetition, identical components and parts are provided with the same reference symbols, if further distinctions are not required or not meaningful.

[0032] figure 1 In a first embodiment, components assigned to the wheels of the axle are shown for realizing an active wheel suspension—designated generally with reference numeral 10 in the following.

[0033] A rotary actuator 12 with a torsion bar 14 is assigned to each wheel. The unit formed from the rotary actuator 12 with the torsion bar 14 also has at least a strut 16 for moment support and a lever element 18 . The torsion bars 14 are each operatively connected to the wheels via lever elements 18 , so that by adjusting the torsion bars 14 accordingly, pivoting movements, body movements, tilting, and pitching movements of the motor vehicle can be influenced. Furthermore, a controller 20 is shown, by means of which the rotary actuator 12 can be ...

Abstract

An actively adjustable wheel suspension for the wheels of an axle of a motor vehicle, wherein each wheel is articulated on the body side of the motor vehicle via a plurality of wheel control elements, includes for each wheel on the axle a rotary actuator which is supported on the body side and includes a torsion bar. The two rotary actuators can be activated for active adjustment via a control unit, with the rotary actuators and the torsion bars of the rotary actuators being oriented in motor vehicle longitudinal direction. The rotary actuators include each at least one strut, which is oriented in motor vehicle transverse direction, for torque support.

Description

technical field [0001] The invention relates to an actively adjustable wheel suspension for wheels of an axle of a motor vehicle. Background technique [0002] So-called active systems for calming the body of a motor vehicle are sufficiently known. Typically for this application a rotary actuator is used to rotate the torsion bar. By applying a torque to the torsion bar, an active force is produced which can influence the wheel motion or body motion of the motor vehicle. [0003] A specific type of actively adjustable wheel suspension for the rear wheels of an axle of a motor vehicle is disclosed in EP 2 389 299 . In this case, each wheel of the axle is supported on the subframe via a plurality of wheel guide elements and is operatively connected via its wheel guide elements to an adjustable torsion bar. To the torsion bars oriented in the transverse direction of the motor vehicle are respectively assigned—also oriented in the transverse direction of the motor vehicle—rot...
