  • Front suspension device
    Patent number: 5868410
    Abstract: A front wheel suspension for motor vehicles is constructed such that an upper link is so connected at one single end thereof to a connecting member as to provide an arrangement wherein loading a wheel support member in the lateral direction with respect to the normal forward driving direction of the motor vehicle induces a reaction force along a link axis of the upper link without inducing any substantial amount of moment about a king pin axis.
    Type: Grant

  • Vehicle suspension system
    Patent number: 5094473
    Abstract: The instantaneous centers of rotation of the front and the rear suspensions of a vehicle are defined by an intersection of lines drawn parallel to the axes of the inboard ends of the respective upper and lower links and passing through the ball joints provided at the outboard ends of the respective upper and lower links. The instantaneous centers of rotation of the front and the rear suspensions are located at approximately the same height and distance on either side of the center of gravity of the vehicle.

  • Vehicle suspension
    Patent number: 5080389
    Abstract: A bell crank is pivotally mounted on a suspension link. One end of the bell crank is connected with an essentially horizontal shock absorber while the other is connected with a pull rod. As the road wheel undergoes vertical displacement the bell crank rotates while also undergoing vertical displacement along with the link it is mounted on. The lever ratio established between the shock absorber and the link thus changes.
