CA 2313900
A suspension system supports an implement on a work vehicle and includes a linkage mechanism providing pivotal connection between the work vehicle and the implement and adapted to pivot in such manner as to permit relative upward and downward movement between the vehicle and the implement while maintaining a controlled or selected orientation between them. A hydraulic actuator capable of extending and retracting is operatively connected between the work vehicle and the implement so as to effect the pivotal motion of said linkage and relative motion between the vehicle and implement. A shock absorber is interposed between the hydraulic actuator and one of the work vehicle and the implement for absorbing shock loadings tending to pass between the vehicle and the implement via said hydraulic actuator when in use. The shock absorber includes an elongated link mounted for pivotal motion at a point between opposing ends thereof. One end portion of the elongated link is connected to an end of the actuator and the other end of the link is in a load transmitting relation to a resilient cushion whereby forces exerted by or on said actuator tend to effect pivotal motion of the elongated link and are transformed into compression forces on the resilient cushion.
