Title:
流体式トルク伝達装置
Document Type and Number:
Japanese Patent JP5246345
Kind Code:
B2
Abstract:
In a torque converter (1), an attachment angle of a turbine blade (41) at a turbine outlet as a fluid outlet of a turbine runner (4) is made smaller than the attachment angle of the turbine blade (41) at a turbine inlet as a fluid inlet of the turbine runner (4). The turbine runner (4) is structured so that a cross-sectional area St of a turbine flow path defined by a turbine shell (40), adjacent turbine blades (41), and a turbine core (42), which is perpendicular to a centerline of the turbine flow path, satisfies |St - Sref|/Sref ‰¤ 0.2, where a reference area Sref is an average of maximum and minimum values of a cross-sectional area of a pump flow path defined by a pump shell (30), adjacent pump blades (31), and a pump core (32) of a pump impeller (3), which is perpendicular to a centerline of the pump flow path.
