A chassis actuator (), in particular for a rear axle steering system, includes a rotational-linear transmission () which is provided for coupling, on the output side, to a chassis element, wherein a rotatable, input-side element () of the transmission () is mounted in a housing () by means of at least one axial bearing (). The transmission () is self-lockingly set by means of an adjustable preloading device (), which loads the axial bearing () with an axial force.

An actuator for rear-axle steering system of a motor vehicle comprises a threaded spindle () which is surrounded by planets (), each provided with a corresponding profiling (), wherein the planets () are guided in a driven cage () and, via further profiling (), contact a nut () that surrounds areas of the planets () provided with said profiling () and is supported with respect to the cage () by rolling bearings (), and wherein the cage () is mounted in a housing () by means of further rolling bearings () and is non-rotatably connected to an output-side component () of a further transmission ().

Electromechanical actuator and rear-axle steering system

Planetary roller screw having a threaded spindle, and having a nut element arranged on the threaded spindle, and having planets arranged distributed around the periphery of the threaded spindle, which mesh on one side with the threaded spindle and on the other side with the nut element, which is rotatably mounted in both axial directions in each case by means of a first bearing on a rotationally driven planet carrier which receives the planets and is rotatably mounted on a housing by means of a second bearing. The planet carrier has a sleeve encompassing the nut element, at the axial ends of which a flange respectively having a first bearing seat of the first bearing and a second bearing seat of the second bearing is arranged, the flanges being connected with play to one another by means of the sleeve in a rotationally fixed manner and axially with actuating play.

An actuator () for a rear axle steering system of a vehicle includes a thrust rod () which is longitudinally displaceable within a housing (). The thrust rod () has a rotation lock () having a guide element () which is guided in the axial direction in a single-part or multi-part slide rail () arranged on the housing (). An elastomer ring () is arranged between the slide rail () and the housing ().

Actuator for a rear axle steering system of a vehicle and rear axle steering system having such an actuator

An eccentric adjusting unit is disclosed, for example, for adjusting a connection point for a control arm of a wheel suspension. The unit may include an electric motor and an eccentric gear section. The eccentric gear section may have an input shaft and an output shaft, wherein the input shaft is configured to be driven by the electric motor and the output shaft rotates eccentrically with respect to an output axis of rotation and can be in operative connection with the connection point or forms this connection point. The eccentric gear section may have a star wheel gear stage.
