Document Type and Number:
WIPO Patent Application WO/2012/128243
Kind Code:
A1
Abstract:
In order to increase the reliability of the operation of a vehicle motor drive device using a two-way roller clutch, provide a vehicle motor drive device with a structure that is provided with: a first-gear two-way roller clutch (15A), located between a first-gear output gear (9A) and an output shaft (7); a second-gear two-way roller clutch (15B), located between a second-gear output gear (9B) and the output shaft (7); a first-gear friction plate (36A), which is provided in a manner so as to be able to move in the axial direction between a position which makes contact with the first-gear output gear (9A) and a position which is estranged therefrom; and a second-gear friction plate (36B), which is provided in a manner so as to be able to move in the axial direction between a position which makes contact with the second-gear output gear (9B) and a position which is estranged therefrom. Therein, the first-gear friction plate (36A) comprises a flange section (37) which faces the side surface of the first-gear output gear (9A), and a guide-boss section (38) which interlocks with the inside of a shift ring (35); and the second-gear friction plate (36B) also comprises a flange section (37) which faces the side surface of the second-gear output gear (9B), and a guide-boss section (38) which interlocks with the inside of the shift ring (35).
