A stabilizer bar includes a first housing configured to be fixed to a first side-bar, and a second housing configured to be fixed to a second side-bar. The first housing incudes a clutch piston that engages a clutch ring fixed to the second housing. The clutch piston is moved axially via a screw actuated by a nut. The nut is rotated via a planetary gearset driven by an actuator.

A mechanically actuated level control valve device for a commercial vehicle with an air suspension system is a level control valve and comprises a drive element that can be mechanically coupled to a vehicle wheel or axle. A valve element and a counter valve element have a first relative position, wherein the port for the air suspension bellow is closed, a second relative position, wherein the port for the air suspension bellow is connected to the port for the aeration device, and a third relative position, wherein the port for the air suspension bellow is connected to the port for the deaeration device. The valve element is coupled to a rotatable driveshaft of the level control valve by a drive mechanism. An integrated actuator changes the relative position of the valve element and the drive element or the relative position of the counter valve element and a valve housing.

An air suspension system of a commercial vehicle comprises an electronic control device with a level control valve device. A valve element is coupled to a drive element mechanically coupled to a vehicle wheel or axle. In a first relative position of the valve element and a counter valve element, a port for an air suspension bellow is blocked. In a second relative position, the port for the air suspension bellow is connected to a port for an aeration device. In a third relative position, the port for the air suspension bellow is connected to a port for a deaeration device. Control logic generates a control signal for an actuator which, when a level change is set by an operator, correspondingly changes the relative position of the valve element and the counter valve element or the relative position of the counter valve element and a valve housing.

A vehicle height control system includes an arm including a first end portion connected to a vehicle body and a second end portion coupled to a wheel, a bearing unit fixed to the vehicle body, a crank coupled to the bearing unit, a push rod including a first end portion connected to the crank and a second end portion connected to the arm, and a spring reaction force variable device coupled to the bearing unit and configured to vary reaction force applied to the crank.

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.

A universal wheel driving system includes a sun gear provided to receive power from a power source, a ring gear provided so that a rotation axis thereof is moved relative to a rotation axis of the sun gear and a wheel is concentrically connected to the ring gear, at least one gear train engaged to the sun gear and the ring gear and configured to allow relative motion between the rotation axes of the sun gear and the ring gear and to form a continuous power transmission state therebetween, a carrier constantly supporting a position of a rotation axis of a final pinion of the at least one gear train with respect to a position of the rotation axis of the ring gear, and a suspension portion configured to support the carrier to be movable upward and downward with respect to a vehicle body.

The invention relates to a device for adjusting the height of a vehicle body, having two components, which can be moved longitudinally relative to each other, and a movement thread, which is arranged between these components. The movement thread includes a partial thread which is designed as a spindle paired with a first component and a partial thread which is designed as a spindle nut paired with the other component. The partial threads are designed to be axially movable relative to each other by a rotational drive. The device also includes a locking device which bridges the movement thread in at least three longitudinal positions and which comprises an axially fixed locking ring that is arranged on the spindle in a rotatable manner and has locking cams distributed over the circumference and a shifting gate that is rigidly connected to the spindle nut in an axial manner, receives the locking cams, and includes locking stops, which are arranged at end positions of the at least three longitudinal positions and are distributed over the circumference, and switching ramps, which lie axially opposite the locking stops, are provided with slopes that decrease in the circumferential direction, and are arranged over the circumference. A movement of the locking cams towards the locking stops and towards the switching ramps in the shifting gate is provided by an axial movement of the spindle relative to the spindle nut, this displacement depending on a rotational direction of the rotational drive, and a selection of the locking stops is carried out by rotating the locking ring by the rotated locking cams resting against switching stops provided between the switching ramps. In order to shorten the switching paths and the switching times of the locking device, at least one switching ramp arranged between two locking stops is expanded relative to the remaining switching ramps in a direction of the locking stops.

A rotational damper includes a damper housing surrounding an electromagnetic damper motor and connected to a first mass via a fastening part; a coupling lever supported for pivoting relative to the damper housing and connected with a second mass; a strain wave gear mechanism for damping vibrations and including a rigid unit having an internal spline and being connected with the damper housing, and a flexible unit having an external spline and being fastened with the fastening part, wherein the first and second units are coupled with each other via the internal and external splines; a wave generator rotatably supported in the flexible unit, wherein a rotation of the wave generator causes a deformation of the flexible unit; and a wrap spring connected on one side in rotative fixed relationship with the coupling lever, and on another side connected in rotative fixed relationship with the fastening part, wherein at a predetermined pivoting of the coupling lever relative to the fastening part the wrap spring deforms the flexible unit thereby blocking the strain wave gear mechanism.

A damping system of a two-track vehicle includes a passive stabilizer having a torsion bar which runs in a vehicle transverse direction and having lever elements which adjoin the torsion bar at the end sides and which are connected to mutually oppositely situated wheel suspension arrangements of an axle of the vehicle. Two actuators are assigned to respective wheels of the wheel suspension arrangements and are mounted on the vehicle body. Each actuator has a drive by way of which a torque can be exerted on that section of the stabilizer which faces toward the respective wheel. Here, the actuators are in the form of electric motors and are designed to dampen vertical vibrations of the respective wheel or of the so-called unsprung mass, and/or vibrations of the vehicle body in a frequency range between 0 Hertz and at least 20 Hertz, through suitable regulation of the drive of the actuators and thus also through active introduction of forces into the system.

An improved adaptive stabilizer bar is provided. The stabilizer bar includes a cycloidal drive between first and second portions of a divided torsion bar. The cycloidal drive includes a cycloidal gear assembly that provides a significant mechanical advantage, allowing relatively small electric motors to be used. In addition, the cycloidal gear assembly has a relatively small physical footprint, particularly when compared to a planetary gear assembly, for example.
