KR950029625A - Stator of torque converter for automatic transmission - Google Patents

Abstract

Torque converter by reducing the fluid loss by minimizing the vortices generated at the tip of the blade by bringing the maximum and minimum values of the fluid flow rates flowing in the suction surface and the pressure surface of the blade close to each other. Its purpose is to provide a stator of a torque converter for an automatic transmission that can increase the efficiency of the adapter, and thus a pump impeller connected to the crankshaft and rotating simultaneously with the operation of the engine, and correspondingly the input shaft spline of the transmission. A turbine runner to be coupled and a stator shaft fixed to the transmission case are provided via a one-way clutch, and the flow direction of oil flowing out of the turbine runner is changed to hit the rear surface of the pump work pela to assist the rotation of the pump. In addition to the streamlined shape on the outer circumference, the oil flow rate is A torque converter for an automatic transmission comprising a stator in which a high pressure suction part and a low flow rate of oil have a plurality of blades having a low pressure pressure part at a predetermined angle, and are inclined in an axial direction. A through hole penetrating the suction portion and the pressure portion is formed to allow the maximum and minimum values of the oil flow rate to be close to each other to suppress the generation of vortices caused at the end of the blade.
