Title:
動力伝達装置
Document Type and Number:
Japanese Patent JP4981993
Kind Code:
B2
Abstract:
Provided is a power transmitting device that lets a motor in a hybrid vehicle be smaller and lighter, prevents internal resistance and inertia of the generator motor from becoming driving resistance, and can effectively utilize energy. Via a first clutch (10), power is transmitted from an input shaft (2) to a transmission shaft (3) but power transmission from the transmission shaft (3) to the input shaft (2) is blocked, and power transmission from the input shaft (2) to the transmission shaft (3) can be blocked. Via a second clutch (20), power is transmitted from the transmission shaft (3) to the input shaft (2), while power transmission from the input shaft (2) to the transmission shaft (3) is blocked. Thus, when driving using only the power of the engine (111), power transmission from the input shaft (2) to the transmission shaft (3) is blocked, thereby preventing transmission of power to a generator motor (112). Consequently, the generator motor (112) can be made smaller and lighter, and energy losses can be prevented.
