    Abstract: A towed implement is provided with ground support wheels mounted to its chassis by trailing wheel support arms and respective suspensions including lift cylinders with which are associated damping devices that operate in such a way as to prevent damage to a respective cylinder from rebounding forces resulting when the suspension is being returned to its operating position by the release of energy stored in spring arrangements of the suspension after being loaded by an obstacle engaging the associated wheel. In one embodiment, the spring arrangement includes a damping spring located between an end of the associated cylinder and piston, and in another embodiment, the spring arrangement includes a gas pressure reservoir which, by virtue the operation of a reversing link in the suspension, is loaded both when the wheel is caused to move in a first direction by engaging an obstacle, and when the wheel is moved in the opposite direction by the airborne wheel once past the obstacle.

    Abstract: A vehicular suspension system having at least one pair of shock absorbers. Each of the shock absorbers of the pair includes a housing defining top and bottom ends and a fluid filled interior chamber, upper and lower ports in communication with the interior chamber, and a piston disposed in the interior chamber which is reciprocally movable through upward and downward strokes therewithin. The lower port of a first shock absorber of the pair is fluidly connected to the upper port of a second shock absorber of the pair via a first fluid line. Similarly, the lower port of the second shock absorber is fluidly connected to the upper port of the first shock absorber via a second fluid line.

    Abstract: A control device for an oscillating axle suspension, in particular a front axle suspension, includes at least of one hydraulic accumulator device (10), a suspension device (12) and a proportional valve (14) having a valve piston (26). The proportional valve (14) is connected to the accumulator and suspension devices (10, 12) via fluid ports (16, 18, 20, 22). The valve piston (26) is actuatable by an electric motor (28), is longitudinally guided in a valve housing (24) of the proportional valve (14) and controls the fluid ports (16, 18, 20, 22) such that, in at least one functional position of the valve piston (26), the axle oscillation is provided while the suspension is blocked and, in at least one further second functional position of the valve piston (26), the suspension is provided while the axle oscillation is blocked.
