DIFFERENTIAL GEAR Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: differential gear comprises driving pinion (15) and three differentials. The first differential comprises outer (9) and central (1) wheels and carrier H1 with satellites (5). The second differential comprises outer (10) and central (2) wheels and carrier H2 with satellites (6). The third differential is spiral and has two engaged satellites (7) and (8). Satellite (7) engages central wheel (4), and satellite (8) engages outer wheel (11). The rotation of central (4) and outer (11) wheels by satellites (7) and (8) is combined in carrier H3. Driving pinion (15) engages carriers H1 and H2 which rotate in opposite directions. Central wheels (1) and (2) are rigidly interconnected through the shaft. Outer wheels (9) and (10) are connected with outer (11) and central (4) wheels of the third differential through pinions with unmovable axles.

EFFECT: improved structure.
