  • Mass spring system with roll/pitch stabilization for use in vehicles
    Patent number: 6056303
    Abstract: A mass spring system for use in a vehicle, in which an unsprung mass is coupled with a support by at least a bearing arm. The mass spring system includes an anti-roll/pitch mechanism including a spring. The spring has a first end coupled with the support and a second end coupled with the bearing arm. The spring defines an axis which can be moved by moving the second end of the spring for exerting on the bearing arm a countermoment corresponding to a load acting on the support. A force component of the spring depends on a distance between the first and second ends of the spring. The second end of the spring can pass through a path, defined on a circle lying on a surface of a sphere, while the first end of the spring lies in a center point of the sphere. The first end of the spring lies outside a plane defined by the circle.
