Abstract: A wheel suspension of a vehicle intended to extend in a transversal direction of the vehicle in association with first and second wheels arranged on opposite sides of the vehicle, comprising: a subframe unit provided with a set of attachment points for attachment of the subframe unit to a vehicle body structure, wherein the subframe unit comprises a cross member extending along the subframe unit in a transversal direction of the vehicle when the subframe unit is attached to the vehicle; at least a first link member arranged on each side of the subframe unit, wherein each first link member is arranged to connect a corresponding wheel or wheel supporting element with the subframe unit via a pivoted connection; and a spring arrangement arranged to act onto each of the first link members so as to provide for a spring suspension of the first and second wheels.

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.
