Differential gear with two axial shafts - is contained in cage, with screw on each side of shafts, and two compression discs

摘要

The differential gear inculdes a pair of axial shafts placed opposite each other axially and contained in a differential cage (11). The opposite facing ends of the axial shafts each have a screw (12L, 13R). A pair of compression discs (13a, b, 16a, b) fit between one of the screw ends and the differential cage. Several pairs of worm gears (12L, 12R) rotate freely in the cage (11). A pressure-piece (17L, 17R) fits between at least one of the compression discs (15a, 16a) and the cage (11) and presses the compression discs against the facing ends of the screws (13L, 13R). USE/ADVANTAGE - The differential gear transmits the torque to the other wheel, even when one wheel is rotating in the air.
