MOTOR DRIVE UNIT

Document Type and Number:

WIPO Patent Application WO/2014/038290

Kind Code:

A1

Abstract:

The rotation of a rotor (7) reaches a sun gear (11) of a gear set (5) through an input shaft (8), and then a stepped planetary pinion (13) moves in a planetary motion so that a small diameter gear (13b) rolls along a ring gear (12). This planetary motion reaches a wheel hub (24) through a carrier (14 (14a, 14b)) and an output shaft (9). A motor-side coupler (25) is set so that the output shaft (9) is drive-coupled to the carrier (14a) in a displaceable manner, and a wheel hub-side coupler (26) is set so that the output shaft (9) is drive-coupled to the wheel hub (24) in a displaceable manner. The center of swinging displacement (01) provided by a bearing (23) for the wheel hub (24) is configured to be located between the center of swinging relative displacement (02) provided by the coupler (25) for the carrier (14a) and the output shaft (9) and the center of swinging relative displacement (03) provided by the wheel hub-side coupler (26) for the output shaft (9) and the wheel hub (24).
