A roll stabilizer for a motor vehicle includes a torsion bar and a vibration damper located on the torsion bar. The vibration damper is configured to vibrate relative to the torsion bar. The vibration damper includes two half-shells formed together about the torsion bar. Damper elements are disposed between the half-shells. The damper elements can be adjusted via an adjustment component to alter the rigidity of the damper elements.

A vehicle with 3 or more wheels includes at least two wheels aligned on the same axis. The vehicle has an intermediate centerline plane between the wheels parallel to a direction of movement, including a mass suspended in relation to the wheels defining a passenger or containment compartment, and two suspension groups kinematically connecting the suspended mass to the two aligned wheels. An anti-roll stabilizer device has at least one compensation mass kinematically connected to the suspended mass via a guide and movable in relation thereto. The anti-roll stabilizer device has a drive of the compensation mass to distance or bring the compensation mass closer to the centerline plane on the side opposite the displacement of a barycenter of the suspended mass with respect to the same centerline plane, to oppose the displacement with respect to the centerline plane of the position of the barycenter of the suspended mass.

A compression-type mass damper may include a damping mass formed with an open space, the damping mass enclosing an outer surface of a target through the open space and absorbing vibration of the target, a weight body enclosed by the damping mass, the weight body applying weight to the damping mass, and a compression plate enclosed by the damping mass, the compression plate applying a fixing force to the open space.

A hydraulic actuator assembly is configured to receive a pressurized fluid from a pump. The hydraulic actuator assembly includes a housing and a piston arranged concentrically with respect to a longitudinal axis, wherein the housing is configured to receive a first portion of the pressurized fluid to displace the piston relative to the housing. The hydraulic actuator assembly also includes a sleeve arranged concentrically with respect to the housing and to the piston, and configured to restrain the piston relative to the housing and receive a second portion of the pressurized fluid from the pump to selectively release the piston. A vehicle including a suspension corner connecting the vehicle's road wheel to the vehicle's body, the fluid pump, and the subject hydraulic actuator assembly to change the vehicle's ride height at the suspension corner is also disclosed. The vehicle may also include a controller configured to control the actuator assembly.

A rotation damper for a motor vehicle. A flywheel driven via a drive with angular velocity and rotating about an axis of rotation is cardanically mounted via a first bearing element and a second bearing element. The flywheel is rotatably mounted on the first bearing element at the rotational angle and the first bearing element is rotatably mounted on the second bearing element at a first rotational angle of a first axis of the flywheel oriented orthogonally to the axis of rotation, and the second bearing element is rotatably mounted at a second rotational angle of a second axis oriented orthogonally to the first axis. The first bearing element is operationally connected to a shaft drive and the second bearing element can be connected by a means to a wheel carrier of the motor vehicle.

A shock absorber includes a first tube defining a first chamber and a piston head movably disposed within the first chamber. A hollow piston rod extends from the piston head. The hollow piston rod defines a rod chamber, and a tuned vibration absorber is disposed within the rod chamber of the hollow piston rod.

Implementations of the present invention relate to devices, systems, and methods for isolating electronic components from input vibrations. The vibration isolation device may passively isolate the housed electronics from substantially all input vibrations. The vibration isolation device may include elastic members to suspend the electronic components within a support frame such that input vibrations are unable to directly influence the electronic components.
