Official abstract text for this publication.
It is provided a vehicle power transmission device having a torque converter and a power transmission mechanism in a power transmission path between an engine and drive wheels, the torque converter including an input-side rotating member disposed with a plurality of pump blades, an output-side rotating member disposed with a plurality of turbine blades receiving a fluid flow from the pump blades, and a stator disposed with a stator blade disposed between the pump blades and the turbine blades, the power transmission mechanism transmitting power input to an input shaft from the torque converter to a subsequent stage, within a circulation flow passage allowing circulation of fluid in the torque converter, a circulation outward passage allowing the fluid to flow toward the inside of the torque converter at the time of the circulation being made up of a gap between the input shaft of the power transmission mechanism and a tubular stator shaft coupled via a one way clutch to the stator, and the stator shaft being concentric with the input shaft and has a diameter larger than the input shaft, the torque converter including a lockup clutch selectively coupling the input-side rotating member to the output-side rotating member, the lockup clutch having a release-side chamber consisting of a portion of the circulation outward passage and having an inner pressure increased by supply of the fluid when the lockup clutch is released, the lockup clutch being disposed on a side opposite to the stator shaft relative to the output-side rotating member, the circulation outward passage including a through-hole penetrating the output-side rotating member in an axial center direction of the torque converter to be in communication with a gap between the input shaft of the power transmission mechanism and the stator shaft, and a gap in the axial center direction between the stator and the output-side rotating member being oil-tightly sealed on an outer circumferential side of the through-hole.
Opening claim text (preview).
The invention claimed is: 1. A vehicle power transmission device comprising: a torque converter and a power transmission mechanism in a power transmission path between an engine and drive wheels, the torque converter including an input-side rotating member disposed with a plurality of pump blades, an output-side rotating member disposed with a plurality of turbine blades receiving a fluid flow from the pump blades, and a stator disposed with a stator blade disposed between the p…
