TORQUE CONVERTER STATOR STRUCTURE

Title:

TORQUE CONVERTER STATOR STRUCTURE

Document Type and Number:

WIPO Patent Application WO/2012/176803

Kind Code:

A1

Abstract:

From among first and second stators (40, 41) of a torque converter supported at a fastening portion by a one-way clutch corresponding to said stators, the number of second stator blades (46) of the second stator (41) at a downstream side of an oil flow is larger than the number of first stator blades (42) of the first stator (40) at an upstream side, and the maximum value (t2) of the blade thickness of the second stator blade (46) is smaller than the minimum value (t1) of the blade thickness of the first stator blade (42). A sufficient opening (β) is secured between the rear edge (42b) of the first stator blade (42) and the front edge (46a) of the second stator blade (46). According to the present invention, an oil flow delay at the opening (β) is prevented, and the oil flow is made efficient due to the large number of first stator blades so that both the capacity coefficient and the torque ratio of the torque converter may be improved.
