機構付きトルクコンバータの油路構造。[Claims for Utility Model Registration] 1. A torque converter incorporates a lock-up clutch piston, and a fluid chamber formed by an integrally coupled shell cover and an impeller is connected to an apply chamber and a release chamber by the lock-up clutch piston. It is divided into two chambers, and the impeller, turbine, and stator are placed on the apply chamber side.
Hydraulic pressure is supplied to the apply chamber from a torque converter supply oil passage formed by an annular gap between the inner diameter of the sleeve integrated with the impeller and the outer diameter of the stator shaft for supporting the stator via a one-way clutch. The hydraulic pressure in the apply chamber is discharged from the torque converter discharge oil passage formed by the annular gap between the inner diameter of the stator shaft and the outer diameter of the turbine shaft supported by the inner diameter of the stator shaft, and is discharged to the shell cover side. The release chamber formed is connected to a lock-up control oil passage formed by an axial hole provided in the center of the turbine shaft, and the oil pressure of the lock-up control oil passage is the same as or equal to the oil pressure of the torque converter supply oil passage. When the oil pressure is higher than that of the torque converter supply oil path, the lock-up clutch is released and rotational force is transmitted from the impeller to the turbine via fluid, and the oil pressure of the lock-up control oil path is lower than the oil pressure of the torque converter supply oil path. In the oil passage structure of a torque converter with a lock-up mechanism, in which the lock-up clutch piston is engaged with the cover shell and rotational force is transmitted to the turbine through the lock-up clutch piston, when The torque converter discharge oil passage between the outer diameter part of the turbine shaft and the outer diameter part of the torque converter is formed by an axial groove that connects both ends of the bushing to the press-fit hole at the tip of the stator shaft for press-fitting the bushing for supporting the turbine shaft. , an oil passage structure of a torque converter with a lock-up mechanism, characterized in that it is connected to an apply chamber. 2. A claim in which, instead of or in addition to the axial groove provided in the press-fit hole of the stator shaft, a notch extending from one axial end to the other end is provided on the outer diameter of the bushing. 1. Oil passage structure of the torque converter with a lock-up mechanism according to 1. 3 Instead of or in addition to the axial groove provided in the press-fit hole of the stator shaft or the notch provided in the outer diameter of the bushing, there is a groove formed in the inner diameter of the bush from one axial end to the other end. 3. The oil passage structure of a torque converter with a lock-up mechanism according to claim 1 or 2, wherein a groove is provided to reach the lock-up mechanism.
