Abstract

A vehicle drive device that includes a speed change mechanism; a fluid transmission device provided closer to an engine attachment side than the speed change mechanism is and including a lock-up clutch; an electric motor having a rotor and a stator and connecting the rotor to an input portion of the fluid transmission device; and an engine power cut-off clutch that transmits or cuts off a driving force of an engine to or from the fluid transmission device.

Description

technical field [0001] The present invention relates to a driving device for a hybrid vehicle having an engine and a motor as a driving source, and more specifically, to a driving device for a vehicle including an engine power interruption clutch in a fluid transmission device with a lockup clutch. Background technique [0002] As a drive device mounted on a hybrid vehicle, a drive device that transmits rotation generated by a drive source to a transmission mechanism via a fluid transmission device with a lockup clutch is widely used. In addition, such a drive device is provided with an engine power interruption clutch that transmits or interrupts the driving force of the engine with respect to the fluid transmission device. Here, the lock-up clutch is a component used to transmit the driving force generated by the power source to the transmission mechanism without passing through the fluid. Once the vehicle speed reaches a preset speed, it will be activated (locked up) to i...
