  • Patent number: 11981178
    Abstract: A stabilizer bar assembly for a suspension system of a vehicle. The stabilizer bar assembly includes a first bar configured to be coupled to the vehicle suspension system proximate to a first wheel. A second bar is adjacent to the first bar. A coupling assembly is at an interface between the first bar and the second bar. The coupling assembly includes a magnetorheological material in contact with both the first bar and the second bar. The magnetorheological material is configured to transform from a fluid state to a viscoelastic solid state when subject to a magnetic field. A magnet is configured to apply the magnetic field to the magnetorheological material. In the viscoelastic solid state, the magnetorheological material resists relative movement between the first bar and the second bar.

  • Patent number: 11872862
    Abstract: A weight balancing system for a vehicle performs a method of adjusting a weight on a wheel of a vehicle. The system includes a processor of the vehicle and a scale. A wheel of the vehicle is placed on the scale, the wheel having an associated spring seat and associated spring. The scale measures a weight placed on the wheel by the vehicle and communicates the weight to the processor. The processor activates the spring seat to adjust a length of the spring, thereby adjusting the weight placed on the wheel by the vehicle.

  • Patent number: 11807061
    Abstract: A vehicle, variable spring system and method of operating a corner actuator coupled to wheel of the vehicle. The vehicle includes the corner actuator and the variable spring system. The variable spring system includes a control chamber coupled to the corner actuator, a first spring, a second spring, and a valve. An applied resistance for the corner actuator is selected by selecting an amount of fluid coupling between the control chamber and each of the first spring and the second spring. A force is absorbed at the wheel using the applied resistance.

  • Publication number: 20100084234
    Abstract: A valve assembly for a damper includes a piston with a central hole to receive a rod and at least one fluid passage spaced form the central hole. At least one deflecting disc is positioned on one side of the piston to at least partially overlap the fluid passage. The deflecting disc includes a center opening that is aligned with the central hole of the piston and is defined by an inner peripheral surface at the center opening. At least one translating disc is positioned in an overlapping relationship with the deflecting disc and is defined by an outer peripheral surface. A cage is positioned over the deflecting and translating discs and includes an abutment feature that constrains the translating disc at the outer peripheral surface while the inner peripheral surface of the deflecting disc is constrained at the rod.
