A motor vehicle (), in particular an autonomous motor vehicle, includes a steering system (), a plurality of wheels () that can be steered by means of the steering system (), and wheel housings () for said wheels (). The steering system () is designed such that the steering system steers the steerable wheels () of a wheel pair in question in the same direction, in the case of joint steering to the left or right at a steering angle α up to a limit angle αdefined by the shape of the corresponding wheel housings (), and in opposite directions, in the case of steering to the left or right at a steering angle α exceeding the limit angle α.

Motor vehicle and method for steering a motor vehicle

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 steering actuator for rear axle steering of a motor vehicle has a spindle drive () which comprises pushrods () which are connected to a threaded spindle () and which are mounted in a housing () by means of plain bearings (), allowing the passage of air, and are connected at each end thereof to an attachment element () provided for coupling to a chassis suspension arm, wherein a gaiter () is connected on the one side to the housing () and on the other side to one of the attachment elements () in each case. Each plain bearing () is designed as a bearing allowing one revolution of the threaded spindle (), wherein at least one longitudinal groove () abuts one guide bush () of the plain bearing ().

Steering actuator

A stabilizer bar has a first connected position and a second disconnected position. One side-bar is fixed to a housing while the other side-bar is fixed to a tulip within the housing. The housing has a plurality of axial grooves. The tulip defines a plurality of slots which are aligned with the grooves when the vehicle is level. A nut has a plurality of pins that extend radially such that the nut is torsionally coupled to the housing. In a first connected position, the pins fit within the slots of the tulip to torsionally couple the nut and the housing to the tulip. To facilitate a second disconnected position, a motor driven actuator moves the nut axially such that the pins no longer engage the slots. When motor power is withdrawn, a spring pushes the nut back to the first connected position.

A wheel module () for a motor vehicle includes a wheel () and a wheel guide () for guiding the wheel (). The wheel guide () includes a wheel carrier unit () for supporting the wheel (); a wheel fork () supporting the wheel carrier unit (); a steering actuator () for adjusting the steering angle of the wheel (); a spring-damper unit (); and a level adjustment unit () for adjusting the height of the vehicle body () of the motor vehicle. The spring-damper unit () is arranged in a region of the wheel guide () between the wheel fork () and the wheel carrier unit ().

Wheel module for a motor vehicle and corresponding motor vehicle

A fork leg for rotating a wheel of a motor vehicle is provided with a fastening flange for the coaxial, torque-proof fastening of a steering rod, an extension region protruding from the fastening flange substantially perpendicularly to the steering axis for bridging a lateral distance to the wheel, a coupling point for the articulated connection of a rocker which is connected to the wheel and a connection piece which is connected integrally to the extension region and to the coupling point, wherein the connection piece is shaped to accommodate a large steering angle.

Fork leg for rotating a wheel of a motor vehicle

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.
