Combined differential gear-and-planetary gear device has differential gear mechanism and planetary gear mechanism set adjacent each other relative to rotation axis of housing

摘要

The device (1) has a housing (2) rotated about a rotation axis (L) and which encloses a differential gear mechanism (4) and a planetary gear mechanism (3) set adjacent each other relative to the rotation axis. The planetary gear mechanism has at least one planetary gear (31) matched to a sun gear (34) and an inner gear (33). The differential gear includes a casing (41) connected to the inner gear and set coaxial with the rotation axis. At least one pinion gear (43) and two side gears (44) are set within the casing and meshed mutually.
