Title:
DRIVE DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2020006940
Kind Code:
A
Abstract:
To provide a drive device for a hybrid vehicle comprising a planetary gear train and two motor generators (MGs), capable of reducing rotation loss when a transmission gear ratio is small, and enhancing power transmission efficiency in high speed travel.SOLUTION: A drive device for a vehicle is configured so that, in an order of arranging rotation members of a first planetary gear set 20 and a second planetary gear set 30, from an end on a common speed diagram, a first member can be coupled to a first MG 60, a second member can be coupled to an input shaft 10, a third member can be coupled to an output shaft 12, a fourth member can be coupled to a second MG 62, one of the second member and the fourth member is set to a low speed stage stationary member, then the low speed stage stationary member is fixed to a stationary part 18 for acquiring a stationary transmission gear ratio on the low speed stage. When the first member is fixed to the stationary part 18 for acquiring a high speed stage stationary transmission gear ratio, the fourth member can be stopped.SELECTED DRAWING: Figure 1
