Differential gear for dividing driving power on part of powertrain section to two output strands of multi-axis driven, multi-track motor car, has output hubs arranged on opposite sides of sun wheel and placed co-axial to differential axles

摘要

The gear has a distributor stage (1) comprising ring gears (4), a sun wheel (5) and a planetary set (6) that couples the ring gears and the sun wheel, where the ring gears circulate around differential axles (X). Another distributor stage (2) comprises two spur gear pins (8, 10) that are coupled with two output hubs (9, 11) over two Oldham couplings (K1, K2), respectively. The output hubs are arranged on opposite sides of the sun wheel of the former stage and placed co-axial to the differential axles. The pins are arranged within a region embraced by spur gear teeth of the sun wheel. The planetary set is designed as a double planetary set.
