The invention relates to an oscillating system with balance shaft for the rigid axle, mainly employed in manufacturing articulated forestry tractors and other equipments which work on rough ground, where one of the axles is required to be an oscillating axle. According to the invention, the oscillating system consists of a balance shaft (B) provided with two supports (P) on which the rigid front axle is mounted and two supports (L) by means of which the two arms of the belaying blade are articulated, a rear bearing system (LS) and a front bearing system (LF) provided with a mechanism (CR) for compensating and adjusting the axial play, the balance shaft (B) being articulated to a rear wall (PS) and to a front wall (PF) belonging to the chassis, by means of the two rear and front bearing systems (LS and LF), respectively, which comprise angular sphere-shaped maintenance-free joints, as well as cylindrical bearings consisting of bushings and bolts, meant to carry over, together, important radial and axial loads, where the oscillating system with balance shaft converts the front axle into an oscillating axle, increases the equipment mobility, having a positive influence in reducing the vibrations transmitted to the bearing structure and improving thereby the ergonomics of the driver's cabin while allowing the belaying blade to follow the ground during the motion on rough ground. |
