Abstract
A torque converter includes a front cover, an impeller, a turbine, and a stator. The impeller forms a fluid chamber together with the front cover. The stator is disposed between an inner peripheral part of the impeller and an inner peripheral part of the turbine. The stator regulates a flow of a fluid flowing from the turbine to the impeller. A flattening ratio is 0.5 or less. The flattening ratio is herein defined as a first ratio of an axial dimension to a radial dimension of a torus formed by the impeller, the turbine, and the stator. A flow area ratio is 0.14 or greater and 0.16 or less. The flow area ratio is herein defined as a second ratio of a minimum flow area of the impeller and the turbine to an area of an imaginary circle having the outer diameter of the torus as the diameter thereof.
Claims3
A torque converter comprising:
- a front cover to which a torque is inputted;
- an impeller forming a fluid chamber together with the front cover;
- a turbine opposed to the impeller, the turbine configured to output the torque;
- and
- a stator disposed between an inner peripheral part of the impeller and an inner peripheral part of the turbine, the stator configured to regulate a flow of a fluid flowing from the turbine to the impeller, wherein
- a flattening ratio is 0.5 or less, the flattening ratio defined as a first ratio of an axial dimension to a radial dimension of a torus formed by the impeller, the turbine, and the stator, and
- a flow area ratio is 0.14 or greater and 0.16 or less, the flow area ratio defined as a second ratio of a minimum flow area of the impeller and the turbine to an area of an imaginary circle having an outer diameter of the torus as a diameter thereof.
