A damper assembly to harvest energy from road deflections including a housing with a first shell, a second shell affixed to the first shell and to a vehicle body, a generator assembly with a first generator nested in the first shell, and a second generator nested in the second shell, a ball screw crossing the housing and with a first terminal portion that protrudes from the first shell and affixed to a wheel assembly of the vehicle, a second terminal portion that protrudes from the second shell, and a central portion extending between the first terminal portion and the second terminal portion, wherein the central portion actuates the first generator to provide a first electrical current when the wheel assembly is displaced in a first direction and the second generator to provide a second electrical current when the wheel assembly is displaced in a second direction.

An electromechanical chassis actuator includes a single electric motor and two screw drives. The two screw drives use a common threaded spindle. A spindle nut of the first screw drive is rotationally fixed to the electric motor's rotor and engages the threaded spindle in a back-driveable manner. A spindle nut of the second screw drive is selectively coupled to the electric motor's rotor by a coupler and engages the threaded spindle in a self-locking (not back-driveable) manner. When the coupler is in an engaged position, the actuator operates in a level-adjustment mode. When the coupler is in a released position, the actuator operates in a damping mode.

A wheel steering system is provided that improves an environment of an actuator being mounted and reduces changes in toe angles of wheels at the time of a suspension stroke. The system includes: right and left hub carriers supported by a rear suspension mechanism; right and left tie rods having outer ends in a vehicle width direction thereof pivotally connected to the right and left hub carriers; and a Watts link having inner ends in the vehicle width direction of the right and left tie rod pivotally attached thereto so as to be pivotable about a pivot axis, wherein the actuator and the Watts link are arranged above springs, and the Watts link is connected with the actuator so as to be displaceable substantially along the vehicle width direction when a driving force of the actuator is inputted to the Watts link.

A robot according to an embodiment of the present disclosure may comprise: a base; a driving wheel protruding downward from the base; a plate spaced upward from the base; a through hole formed at the plate; a suspension bar including a shaft part rotatably connected to the base and vertically extending upward, and a screw part vertically extending from an upper end of the shaft part toward the through hole; a slider sliding along the shaft part and connected to the driving wheel; a bushing top configured to move up and down along the screw part when the suspension bar rotates; a spring located on an outer circumference of the suspension bar and located between the bushing top and the slider; and a motor disposed above the plate and connected to the screw part through the through hole to rotate the suspension bar.

The invention relates to a stabilizer assembly of a two-track vehicle for stabilizing a rolling movement, the stabilizer assembly being operable on at least two different spring characteristics, comprising a first and a second stabilizer half, each coupled to a wheel of the vehicle, wherein the first and the second stabilizer halves are coupled such that they can rotate relative to each other about their longitudinal axis by means of a spring element, whereby the stabilizer is operable with a first spring characteristic, and wherein the first and the second stabilizer halves can be hydraulically coupled such that they can rotate relative to each other about their longitudinal axis by means of a hydraulic actuator, whereby the stabilizer is operable using at least one second spring characteristic. The actuator comprises at least two work chambers which are filled with a hydraulic medium and coupled to each other by a fluid-conducting connection, and the actuator comprises a transmission unit which is designed such that a rotational movement of the stabilizer halves can be converted into a translational movement of an intermediate element arranged between the two work chambers, and a volume flow of the hydraulic medium from the one work chamber into the other work chamber can thus be produced.

An adjustable shock adapter for converting a non-adjustable shock into a shock with full spring and ride height adjustment is provided. The adjustable shock adapter may include a tubular component adapted for engagement with a shaft of the non-adjustable shock. The tubular component may include a rim extending radially outward from an outer surface of the tubular component, located towards the bottom of the tubular component, and positioned against a fixed component of the shock absorber to prevent the tubular component from sliding past the component. The adjustable shock adapter may also include a collar mounted to the outer surface of the tube-shaped component and moveable upwards or downwards along the tubular component and locked into place. The collar may include a second rim positioned against a spring of the non-adjustable shock, acting as a stopper to limit how low the height of the UTV can be adjusted.
