Abstract

Provided is a power transmission device which allows a torque converter to be miniaturized and the freedom of layout inside said torque converter to be further improved. The device is equipped with a torque converter (1) having a torque amplifying function, a clutch means (3) which is enabled when the vehicle is moving forward and that has a first clutch means (3a) that transmits the drive force of an engine to drive wheels via the drivetrain of the torque converter (1) and a second clutch means (3b) that transmits the drive force of the engine to the drive wheels without involving the drivetrain of the torque converter (1), a selection means (4) for selectively activating the first clutch means (3a) or the second clutch means (3b) according to the vehicle status, and a damper mechanism (7) capable of reducing torque variation which is provided in the drivetrain between the engine (E); and the torque converter (1).

Description

technical field [0001] The present invention relates to a power transmission device which is provided in the middle of a power transmission system from a driving source of a vehicle to wheels, and which can optionally and selectively transmit or cut off the driving force of the driving source to the wheels. Background technique [0002] In prior art vehicle power transmission devices (automatic transmissions), a type with a torque converter (so-called "torque converter type" starting type) and another type with a starting clutch (so-called "Starting clutch type" starting type). In a torque converter type automatic transmission, starting performance can be improved due to the torque amplifying function of the torque converter at the time of vehicle startup. On the other hand, in a launch clutch type automatic transmission, since it does not have any slippage that would be found in a torque converter during, for example, smooth running of the vehicle, power transmission effic...
