２モータ車両駆動装置
Document Type and Number:
Japanese Patent JP6453700
Kind Code:
B2
Abstract:
Helical gears in gear trains of speed reducers 2L, 2R generate thrust forces in directions not to separate a speed reducer casing 20 which has an axial three-piece structure, whereby leakage of lubricant oil from between separated surfaces in the speed reducer casing 20 is prevented. Output gears 25L, 25R which generates large thrust force on the final stage in each gear train of the speed reducers 2L, 2R both generates inward forces, so that the center casing 20a does not receive forces in directions in which the left and the right casings 20bL, 20bR is separated therefrom.
