Steerable parallel axle gear differential

摘要

The parallel axle gear differential (10) comprises a housing (12) with a flange end (14) and lid end (16), that is connected together, via four struts (18). The flange end has holes to attach gear rings on the housing to transmit motor power. The flange and lid ends are connected with the struts, via non-aligned bolts (22,24). The housing is rotatable around a common axle (32), with two exit shafts (34,36) in forward drive (38) and reverse drive (40) directions. Side wheels (42,44) are coupled with the inner ends of both exit shafts, so that they, and the housing, can rotate about the common axle. The side wheels are linked, at their bases, to four planet wheel pairs (46), with each pair having an advancing planet wheel element (48) and a following planet wheel element (50). They are both rotatable about the common axle, a parallel axle (52) etc.
