Abstract:
A torque converter comprising a pump impeller connected to a driving shaft, a turbine impeller connected to a turbine shaft, a stator impeller disposed between said pump impeller and said turbine impeller, and a free wheel which is interposed between said stator impeller and a stationary structure and operable to lock said stator impeller in order to allow said stator impeller to bear a reaction force generated with the amplification of torque between said pump and turbine impellers,wherein a stator shaft connected to said stator impeller is disposed with a tip end thereof being passed through said turbine shaft to protrude outside said turbine shaft, the tip end of said stator shaft being connected to said stationary structure through said free wheel, wherein said turbine impeller is disposed at a location displaced from said pump impeller toward a case carrying said driving shaft; said turbine shaft protruding toward said case is secured to said turbine impeller; said free wheel is interposed between the tip end of said stator shaft passed through said turbine shaft and said case; and said turbine shaft is provided with a driving gear of a primary reducing device, which connects said turbine shaft and an input shaft of a transmission to each other between said turbine impeller and said free wheel.
