Abstract

A drive device for a vehicle, having an engine power disengaging clutch mounted in a lockup clutch-equipped fluid power transmitting device, wherein controllability and torque transmission capacities of both the clutches are increased, the amount of heat generation of friction materials when the clutches are engaged is reduced, the drive device allows a fluid drive device to be configured withoutan increase in the size thereof, and the drive device is configured without an increase in the size thereof. The lockup clutch and the engine power disengaging clutch are respectively formed as multi-plate clutches having actuators. Friction plates of the lockup clutch are provided on the outer diameter side of a torus. The engine power disengaging clutch is formed to have a smaller diameter thanthe lockup clutch. The engine power disengaging clutch is provided in a torque converter. On the outer diameter side of the engine power disengaging clutch, a motor generator is mounted overlapping axially the friction plates of the engine power disengaging clutch.

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...
