  • Adjustable rate leaf spring suspension
    Patent number: 8678410
    Abstract: A suspension for a motor vehicle has a sub-frame and first and second control arm movably attached to opposite ends of the sub-frame. A leaf spring extends transversely across the sub-frame, a first end acting on the first control arm and a second end acting on the second control arm. A first spring seat is located between the leaf spring and the sub-frame, and is movable over a first range of positions relative to the leaf spring. A second spring seat is located between the leaf spring and the sub-frame, the second spring seat movable over a second range of positions relative to the leaf spring. An actuator is operatively connected to the first and second spring seats to move the first and second spring seats across their respective ranges of positions, thereby changing a spring rate of the leaf spring.
