<p>It is especially applicable for load-bearing vehicles such as tractors, dumpers, farm machinery, wheelbarrows, etc. The directional shaft (1) includes a "U"-shaped flange (4) at each end. The arms (5, 6) have both openings (8, 9) aligned, and their axis (18) is the same as that which runs through the half-shafts defined at the end areas of some extensions (14, 15) provided on a hinge joint (10) to which the motor reducer (3) turning the appropriate wheel is anchored. The hinge joint (10) has a side arm (19) connected to the directional cylinder (21). The axis (18) is resolved at the upper section by means of a cylindrical neck (16) open to the inside of the hinge joint (10), passing through the opening (8) of the flange, with a bearing (22) in between. By way of this arrangement, the flexible metal connectors and other access conduits can pass through the axial emptying in the cylindrical neck (16) of the hinge joint (10), to the motor reducer and to the brake system of the wheels (2) without any rubbing or twisting which might lead to their premature wear. <IMAGE></p> |
