  • Variable rate flat spring arrangement
    Patent number: 11001114
    Abstract: A suspension system for a vehicle includes a first chassis rail and a second chassis rail, each extending longitudinally in an axial direction of the vehicle. Also included is a first leaf spring element extending longitudinally in the axial direction of the vehicle, the first leaf spring element operatively coupled proximate ends thereof to the first chassis rail and at an intermediate location to an axle assembly of the vehicle. Further included is a second leaf spring element extending longitudinally in the axial direction of the vehicle, the second leaf spring element operatively coupled proximate ends thereof to the second chassis rail and at an intermediate location to the axle assembly of the vehicle. Yet further included is at least one leaf spring extending in a transverse direction of the vehicle, the at least one leaf spring having a spring rate that is actively variable.

  • Variable rate flat spring arrangement
    Patent number: 10703156
    Abstract: A suspension system for a vehicle is provided. The suspension system includes a first chassis rail extending longitudinally in an axial direction of the vehicle. The suspension system also includes a second chassis rail extending longitudinally in the axial direction of the vehicle. The suspension system further includes a transverse beam coupled to the first chassis rail and the second chassis rail. The suspension system yet further includes at least one leaf spring extending in a transverse direction of the vehicle, the at least one leaf spring having a spring rate that is actively variable. The suspension system also includes a fulcrum locator operatively coupled to the at least one leaf spring and to the transverse beam, the fulcrum locator in a sliding relationship with the at least leaf one spring.
