Abstract: A steering assembly for a work vehicle having a supporting frame is disclosed wherein the steering assembly includes a steerable front axle having an axle defined longitudinally by end portions rocking about respective substantially vertical axes. Each end portion supports a rotatable wheel. The front axle further has a box body connected rigidly to the axle to connect it to the frame in freely rotating manner via the interposition of a first spherical joint. A connecting unit connects the front axle stably to the frame to enable the loads on the wheels to be transmitted to the frame. The connecting unit is provided with a shock-absorbing device for elastically disconnecting the front axle from the frame.
