FIELD: transport and agricultural engineering. ^ SUBSTANCE: proposed driving axle has housing, drive shaft, final drive in form of drive pinion and driven gear, differential case central hole fitted on bearings in housing and rigidly connected with driven gear, two driven shafts with screw thread, member movably connecting driven shafts by meshing with screw thread through solids of revolution and passing through central hole of differential case coaxially with case for axial displacement in said hole, and springs. Cavities, for instance, semi-spherical ones, are made in central cylindrical hole of differential case. Connecting member is made in form of cylindrical bushing on outer surface of which longitudinal grooves are made, for instance, with semispherical bottom, parallel to its axis, and on ends of inner surface cavities are made, for instance, semispherical ones. Ends of driven shafts from side of differential case are provided with outer thread and are installed in bushing for rotation. Bushing can be displacement both relative to differential case by means of solids of revolution, for instance, balls installed by one half in cavities of inner cylindrical surface of differential case and by other half, in longitudinal outer grooves of bushing and relative to driven shafts, by means of solids of revolution, for instance, balls installed in cavities of bushing and contacting with thread of driven shafts. Driven shafts are provided with stops to limit travel of bushing along driven shaft made, for instance, in form of beads on shafts and coil springs placed between beads and end faces of bushing. Cavities are made on end faces of driven shafts arranged inside differential case in which solids of revolution, for instance, balls are fitted. ^ EFFECT: simplified design, operation and repair of driving axle improved efficiency of its operation. ^ 3 cl, 3 dwg |
