Abstract

There is provided a power transmission apparatus for a hybrid vehicle, which enable the power transmission efficiency of a hybrid vehicle to be improved. An engine output shaft and a motor output shaft are coupled to a primary shaft of a continuously variable transmission installed in the power transmission apparatus. An output clutch is disposed between an output transmission shaft coupled to a drive wheel and a secondary shaft in order to switch these shafts between a coupled state and a released state, and a drive changeover clutch is disposed between the primary shaft and the output transmission shaft in order to switch these shafts between a coupled state and a released state. In a direct coupling mode where the output clutch is released and the drive changeover clutch is coupled, an engine output is transmitted to the drive wheel without passing through the continuously variable transmission.

Description

technical field [0001] The present invention relates to a power transmission device for a hybrid vehicle that transmits engine output and motor output to drive wheels. Background technique [0002] A hybrid vehicle is a hybrid vehicle in which an engine and an electric motor are mounted on the vehicle, and the output of the engine and the motor are transmitted to the driving wheels, and the output of the engine is transmitted to the driving wheels through a transmission mechanism. In a hybrid vehicle equipped with a speed change mechanism, the arrangement of the engine and the electric motor includes the arrangement of the engine and the electric motor on both sides of the speed change mechanism (the engine is arranged on one end side of the transmission input shaft of the speed change mechanism, and the other end The electric motor is arranged on the side of the transmission), and the mode of adjoining the engine and the electric motor is arranged on the one end side of the...
