1. Device for blocking the oscillating motion of a pendulum axle of a wheeled vehicle having a swing gear carrying an extension arm, in particular a wheel loader, the pendulum axle being engaged with hydraulic cylinder-piston aggregates (15) the working areas (16) of which are connectable with each other through check valves (14) opening into working areas (16) and via a line (3, 11, 12) with a hydraulic pressure source (2), wherein the check valves (14) can be controlled to be opened by a pressure source, which can be connected with the check valves (14) via a control-line (11, 12) and through a control valve (8) actuated by the swing gear of the vehicle and wherein the control valve (8) is cooperating with a cam plate (5) pivoting with respect thereto, which is drivingly connected with a part of the swing gear, preferably with the swinging part thereof, characterised in that the line (3, 11, 12) connecting the hydraulic pressure source (2) with the working areas (16) of the hydraulic cylinder-piston aggregates (15) is the control line (11, 12) itself which opens the check valves (14) via the control valve (8). |
