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.

Chassis actuator and method for operating a transmission assembly of a chassis actuator

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

A ball screw nut having a tubular sheet metal body with a thread profile and being optionally encapsulated in plastic. This sheet metal body is formed of a sheet metal part that includes the thread profile and a ball-returning piece inserted therein, which is designed as an additional sheet metal part.

Ball screw nut

The invention relates to a method for producing a spindle for a ball screw, including the following steps: &#x2014;introducing, at least in sections, a thread profile into a flat material section, &#x2014;shaping the material section to a hollow cylindrical case, two lateral edges of the hollow cylindrical case abutting each other and the thread profile being oriented radially outwards, &#x2014;connecting the two lateral edges of the hollow cylindrical case, and &#x2014;forming, at least in sections, a supporting structure on a radially inner face of the hollow cylindrical case to finish the spindle. A spindle for a ball screw in hybrid design can thus be manufactured in a simple manner. The spindle can be produced cost-effectively and yet has high wear resistance and excellent mechanical load-bearing capacity as well as light weight. The invention further relates to a spindle manufactured according to the invention, for use in a ball screw.

A level adjustment device for a vehicle, comprising a damping device having a piston-cylinder unit and a screw drive, and an adapter sleeve that axially supports a spindle of the screw drive and includes a flange directed radially inwards, wherein the adapter sleeve is configured to utilize the screw drive and is decoupled in relation to a cylinder of the piston-cylinder unit via one or more elastic elements.

Device for level adjustment for a motor vehicle

Bearing bushes, for example, for a chassis of a motor vehicle are disclosed. A bearing bush may include a shaft, a hub, and an elastomer element which is arranged radially therebetween. The bearing bush may be configured to be switched between a first and second stiffness levels. The hub may have a main body and a plurality of radially adjustable plungers which are arranged in the main body. The plungers may be configured to engage the elastomer element and change the stiffness of the bearing bush from the first stiffness level to the second stiffness level. The elastomer element may have a plurality of radial elements arranged on the main body and configured to be compressed via a respective plunger in order to increase the stiffness of the bearing bush. An actuator including an electric motor may be configured to radially adjust the plungers in the main body.
