Vehicular torque converter
Abstract:
A vehicular torque converter includes: a pump impeller having a pump covering and vanes disposed within an output-side portion of the pump covering; a turbine impeller having vanes opposed to the pump impeller vanes; a stator impeller; a one-way clutch between the stator impeller and a stationary member; and a lock-up clutch configured to connect the turbine impeller to an inner surface of a wall of said pump covering. The vanes are offset with respect to the one-way clutch toward the output side. The vehicular torque converter further includes: a thrust bearing between the stator impeller and the turbine impeller, the thrust bearing having a sliding surface with respect to the stator impeller, the sliding surface being positioned radially outwardly of the one-way clutch and offset from an end face of each of sprags of the one-way clutch toward the output side.
