Title:
流体式クラッチ装置
Document Type and Number:
Japanese Patent JP2004511733
Kind Code:
A
Abstract:
A hydrodynamic coupling device, in particular a torque converter or fluid clutch, comprises a housing assembly, a turbine wheel provided inside the housing assembly, and a torque converter lockup clutch assembly for establishing a torque transmission connection as desired between the turbine wheel and the housing assembly. The torque converter lockup clutch assembly comprises at least one essentially annular friction element, which is connected to the turbine wheel for mutually rotating about a rotational axis, and a pressing element which is connected to the housing assembly for mutually rotating about the rotational axis. The at least one friction element can be subjected to the action of the pressing element in order to establish the torque transmission connection between the turbine wheel and the housing assembly. The ratio of a flow outside diameter in the area of the turbine wheel to a friction outside diameter of the at least one friction element ranges from 1.30 to 1.80, preferably from 1.35 to 1.70, and/or the ratio of a friction outside diameter of the at least one friction element to a friction inside diameter of the at least one friction element ranges from 1.10 to 1.25, preferably from 1.15 to 1.20.
