Date Apr. 25, 1985.An improvement in a working vehicle, such as a tractor, which includes a first frame part to which a steering wheel axle is coupled and a second frame part to which a second wheel axle is coupled with the frame part being pivotally interconnected to allow steering of the vehicle and wherein one of the wheel axles is swivelly mounted to its respective frame part to rock about a substantially horizontal axis so that one end of the rocking wheel axle is elevated when the vehicle is driven over uneven terrain. The improvement comprises bracing apparatus including at least two piston-cylinders, at least one of which is coupled to the frame part to which the rocking wheel axle is coupled and to the rocking wheel axle on one side of the frame part, the other piston-cylinder being coupled to the frame part and to the rocking wheel axle on the other side of the frame part, and a system for actuating only the piston-cylinder that is coupled to the side of the rocking wheel axle which is on the steering direction side to counteract the elevation only of that end of the rocking wheel axle on the steering direction side to which the steering wheel axle is turned. |
