In some examples, a vehicle suspension for supporting, at least in part, a sprung mass, includes a damper connected to the sprung mass, the damper including a movable piston. The vehicle suspension further includes an actuator and a controller. The controller may be configured to determine a frequency of motion associated with the sprung mass. When the frequency of motion is below a first frequency threshold, the controller may send a control signal to cause the actuator to apply a deceleration force to the sprung mass. Further, when the frequency of motion associated with the sprung mass exceeds the first frequency threshold, the controller may send a control signal to cause the actuator to apply a compensatory force to the sprung mass. For instance, a magnitude of the compensatory force may be based on a friction force determined for the damper.

A high-pressure gas spring for vehicle suspension systems includes an integral gas damping system and an integral counter spring to reduce spring residual force at suspension rebound. The gas spring includes an inverted piston feature that reduces the overall length of the device. Additionally, there are other innovative features incorporated in the gas spring to improve performance, reduce cost and minimise weight.

Disclosed are a suspension mount structure of an electrified vehicle and a method for evaluating performance thereof. The suspension mount structure includes an upper structure of the electrified vehicle; and a suspension on which the upper structure is mounted, wherein vibration occurring at a location below the suspension is transmitted to the suspension via an axle and then is transmitted to the upper structure via the suspension, wherein the suspension includes a spring and a damper, wherein the spring and the damper are connected in series to each other and are connected in series to the upper structure.

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.

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 mounting structure of a dynamic damper capable of effectively reducing the vibration of a vibration body is provided. The mounting structure includes a suspension member 100 inhibiting the upward shift of a mass member 5. The suspension member 100 and plates 3 are configured as separate members, so that as compared with the case where a pair of plates 3 are coupled, the opposite interval between the plates 3 can be determined without being affected by the dimension accuracy of such the coupling portion. Thus, the thicknesses of the rubber elastic bodies 4 can foe formed at high accuracy, so that the mass member 5 can be easily vibrated at the desired frequency. Therefore, the vibration of the suspension member 100 can be effectively reduced.
