  • Patent number: 4478396
    Abstract: An elastic support structure for a wheel suspension mechanism of a wheeled vehicle, comprising a first rigid member to be subjected to shocks and vibrations produced in a tire-and-wheel assembly, a second rigid member to which shocks and vibrations may be transmitted from the first rigid member, the first and second rigid members being movable with respect to each other when the first rigid member is subjected to the shocks and vibrations produced in the tire-and-wheel assembly, and an elastic member composed of at least two segments constructed independently of each other in at least one plane parallel with the direction in which the first and second rigid members are to be displaced with respect to each other, the segments of the elastic member being constructed of the same material and being similar in geometry.

  • Patent number: 4477061
    Abstract: A MacPherson strut type suspension including a shock absorber operatively disposed between vehicle wheels and a vehicle body of a motor vehicle, the shock absorber having a piston rod; a coil spring disposed in association with the shock absorber to elastically support the vehicle body; a core member secured to an end of the piston rod of the shock absorber; an insulator rubber securely connected between the core member and the vehicle body; and a stop device for restricting the movement of the core member in the axial direction of the piston rod of the shock absorber when the axial movement of the piston rod exceeds a predetermined distance, thereby effectively damping high and low frequency vibrations applied to the suspension while prolonging the life of the insulator rubber.
