  • Patent number: 7543832
    Abstract: Various embodiments of variable rate stabilizer bars are disclosed, including apparatus, vehicle, and kit implementations. Embodiments may have first and second stabilizer bar members. Each stabilizer bar member may be adapted to be operatively coupled to a respective, opposite ground-engaging element of a vehicle. Each stabilizer bar member may be configured to experience a torque about their longitudinal axis upon movement of the respective ground-engaging element relative to the vehicle when operatively coupled to the ground-engaging elements. Embodiments may have a torque transfer regulator, which may be operatively coupled to both stabilizer bar members. The torque transfer regulator may be configured to transfer a portion of the torque experienced by one of the stabilizer bar members to the other stabilizer bar member. Some embodiments may provide for active control of the degree of torque transfer from one ground-engaging element's suspension system to the other.

  • Patent number: 6702265
    Abstract: A balance suspension system for a vehicle having a body and at least four wheels (FR, FL, BR, BL) independently supported for movement between upper and lower positions relative to the body, the suspension system includes a balance mechanism adapted to support suspension forces in the vehicle and a plurality of actuating elements (73, 74, 78, 79) which are responsive respectively to the positions of the wheels relative to the body and are operable on spaced apart points on the balance mechanism. The system also includes control means for controlling relative movement between the balance mechanism and the body. The control means act to redistribute suspension forces between the body and the wheels, thereby to induce predetermined suspension behaviour.

  • Patent number: 6491291
    Abstract: A suspension system includes a SMA suspension component, an actuator and a controller. Altering the mechanical characteristic of the SMA suspension component alters the kinematic properties of the vehicle wheel relative to the vehicle body and the suspension characteristics of the vehicle. In one disclosed embodiment a SMA suspension spring is height adjustable to alter the vehicle handling characteristics. In another disclosed embodiment a SMA suspension component stabilizer bar is shape adjustable. The SMA stabilizer bar is maintained in a first shape to provide a first handling characteristic. To provide a second handling characteristic the SMA stabilizer bar is moved into contact with a fixed vehicle component such as a vehicle frame component. The flexibility of the stabilizer bar is thereby reduced and the vehicle handling characteristics are optimized for a second condition.
