To provide a driving force transmission device which suppresses an increase in weight and size.SOLUTION: According to the present invention, a driving force transmission device includes an electric motor with an output shaft arranged on a shaft on which a shaft center is different between an input shaft and an output shaft of a transmission, a first driving force transmission path for performing power transmission between the electric motor and the input shaft of the transmission, a second driving force transmission path for performing power transmission between the output shaft of the transmission and the electric motor, a first clutch provided on the first driving force transmission path, and a second clutch provided on the second driving force transmission path. In a power running mode for transmitting power from the electric motor to the input shaft of the transmission, the first clutch is closed and the second clutch is released, and in a regeneration mode for transmitting power from the output shaft of the transmission to the electric motor, the first clutch is released and the second clutch is closed.SELECTED DRAWING: Figure 1
【課題】重量の増加および大型化を抑制した駆動力伝達装置を提供すること。【解決手段】本発明の駆動力伝達装置では、変速機の入力軸および出力軸とは軸心が異なる軸上に出力軸を配置した電動機と、電動機と変速機の入力軸との間で動力伝達を行う第1駆動力伝達経路と、変速機の出力軸と電動機との間で動力伝達を行う第2駆動力伝達経路と、第1駆動力伝達経路上に設けられる第1クラッチと、第2駆動力伝達経路上に設けられる第2クラッチとを備え、電動機から変速機の入力軸に動力を伝達する力行モードでは、第1クラッチを締結するとともに、第2クラッチを解放し、変速機の出力軸から電動機に動力を伝達する回生モードでは、第1クラッチを解放するとともに、第2クラッチを締結するようにした。【選択図】 図1
