Title:
POWER TRANSMISSION DEVICE FOR ELECTRIC VEHICLE
Document Type and Number:
Japanese Patent JP3287972
Kind Code:
B2
Abstract:
PURPOSE: To compactly form an electric vehicle power transmission device having a planetary gear type reduction gear mechanism and a bevel gear type differential mechanism.
CONSTITUTION: Each three of the complex planetary gear 30 of a reduction gear mechanism 12 and the driving bevel gear 54 of a differential mechanism 13 are provided at equal angular intervals about one center line O, and arranged, so as to be staggered from each other at equal angular intervals (60-degree intervals) about the center line O. As a result, the mechanisms 12 and 14 can be overlapped on top of each other along the center line O, so as to avoid interference, and approximately a half of the mechanisms 14 are concealed behind the internal surface of a small diameter pinion 26 along the center line O.
