A method for operating a rotation damper for a motor vehicle which has an electric generator with a stator and a rotor includes detecting with a direction of rotation detection module a change of a direction of rotation of the rotor relative to the stator between a first direction of rotation and a second direction of rotation which is opposite to the first direction of rotation; generating with the direction of rotation detection module a signal indicative of an actual direction of rotation of the rotor relative to the stator; and as a function of the signal conducting an electrical current converted by the electric generator to a first electrical load having a first resistance value when the rotor rotates in the first direction of rotation, or to a second load having a second resistance value when the rotor rotates in the second direction of rotation.

A linear actuator comprising a housing with a proximal end and a distal end, the housing defining a central cavity extending axially through the housing; a piston tube, where a first portion of the piston tube is slidably positioned axially in the housing, and a second portion of the piston tube extends outwardly from the distal end of the housing; an elongated rotatable screw positioned axially within the central cavity of the housing; a nut positioned within the housing and mounted about the screw, the nut configured to move axially within the housing as the screw rotates; and a spring positioned around the screw, the spring positioned within the housing between the nut and the piston tube; wherein the spring is configured to bias the piston tube away from the nut.

A spring isolator pad for a suspension assembly for a vehicle may be provided. The spring isolator pad may include a rubber isolator pad for supporting a coil spring operably coupled to a control arm, and a structural insert for supporting a coil spring and the rubber isolator pad. The rubber isolator pad may be operably coupled to the structural insert and comprises a first plurality of extensions. The structural insert may include a second plurality of extensions and a base. The control arm may include a spring link with an orifice. The structural insert may engage with the rubber isolator pad and the spring link to limit rotation of the coil spring relative to the control arm responsive to compression cycles via the first plurality of extensions and the second plurality of extensions.

The present disclosure generally relates to an omni-direction wheel system and methods for controlling the omni-direction wheel system. The omni-direction wheel system includes a plurality of suspension systems that operate independently of one another. Each suspension system may include an electromagnetic steering hub configured to rotate a wheel 360 degrees about a vertical axis based on a polarity of an electromagnetic signal applied to the electromagnetic steering hub. The suspension system may further include an in-wheel motor configured to rotate with the wheel and drive the wheel about a horizontal axis.
