  • Vehicle wheel suspensions using spring combined with flexible armoring for modifying the stiffness curve
    Patent number: 6237901
    Abstract: A suspension for a vehicle wheel includes at least one helicoidal spring and at least one flexible retaining and connecting armoring, which in working position, stresses a portion of the spring by maintaining it compressed to obtain two different stiffness curves.

  • Suspension of vehicles using two stiffnesses, adapted respectively for obtaining a good level of comfort and a good level of behavior
    Patent number: 5263695
    Abstract: A suspension for a vehicle wheel, comprising an elongated shock absorber (7) having an elongated body (6) and first and second abutments at opposite ends of the shock absorber. First and second coil compression springs (R20, R30) are aligned with each other and surround the shock absorber (7). One of these springs bears against one of the abutments and the other of the springs bears against the other of the abutments. A cup (32) is disposed between the springs, this cup surrounding the body and being movable lengthwise of the body. Both of the springs bear on the cup (32). An annular jack (5) is fixed to and surrounds the body and comprises one (10) of the abutments. A third abutment (31) is fixed to the body a distance from the jack (5). An elastic ring (54) is compressible between the cup (32) and the third abutment (31).

  • Vehicle wheel suspension method
    Patent number: 5244190
    Abstract: The invention has for its object a suspension with dynamically variable flexibility or stiffness. The suspension process uses one or several elastic elements mounted opposite each other, so as to impress on the vehicle suspension a variation of stiffness or of flexibility having two slopes on the curve (shock-relaxation and compression effort) and the use of different stiffnesses or flexibilities is localized during operation of the suspension in the vicinity of the position of the loaded vehicle on its wheels and that the least stiffness is located on the second portion of the course of collapse of the wheel suspension. The invention is applicable to suspensions particularly for automotive vehicles.

  • Suspension process and apparatus of the type having different stiffnesses with provision to smooth the change from one stiffness to another
    Patent number: 5183285
    Abstract: A suspension for the wheels of a motor vehicle, the suspension having an operating load position in which the suspension is deformed by a force equal to the weight of the vehicle, a suspended wheel position in which the suspension is deformed by a force less than the weight of the vehicle and a collapsed position in which the suspension is deformed by a force greater than the weight of the vehicle. The suspension has a stiffness that is greater between the operating load position and the suspended wheels position than between the operating load position and the collapsed position. A gradual transition is provided between these stiffnesses.
