Kind Code:
A1
Abstract:
An automobile drive unit (20) comprises a motor (21) for rotatingly driving a
motor side rotating member (30), a reduction gear mechanism (31) for reducing
the rotational speed of the motor side rotating member (30) and transmitting
the reduced rotational speed to a wheel side rotating member (38), and a differential
gear mechanism (41) for distributing the rotation of the wheel side rotating
member (38) to left and right drive shafts (15a, 15b). The reduction gear mechanism
(31) includes a reduction gear rotating shaft (32) having eccentric parts (32a,
32b), curved plates (33, 34) as revolving members rotatively held by the eccentric
parts (32a, 32b), a plurality of outer pins (35) as outer peripheral engagement
members held at fixed positions on a casing and engaged with the outer peripheral
parts of the curved plates (33, 34), and a motion converting mechanism for transmitting
the rotating motions of the curved plates (33, 34) to the wheel side rotating member
(38).
