The stator assembly includes: a stator including at least one stator blade axially disposed between the turbine and the impeller; a one-way clutch including an outer race non-rotatably connected to the stator and an inner race arranged to non-rotatably connect to a stator shaft; and a combination washer and seal including a first portion axially disposed between the turbine shell and the stator and a second portion extending radially inwardly from the first portion and arranged to at least partially seal against the stator shaft.

The present invention relates to a lock-up device for a torque converter which has a simple structure compared to the prior art, which reduces manufacturing costs, and which may reduce a size of the entire torque converter and improve a damping ability of the dynamic damper by minimizing an installation space of a dynamic damper.

In one aspect, a control method and a control apparatus are provided for protecting a damper clutch of a vehicle. In one aspect, the control method of protecting the damper clutch of the vehicle includes determining whether a vehicle state satisfies a condition for operating a damper clutch protection logic, calculating a slip power in real time on the basis of a turbine speed of a torque converter, an engine speed, a capacity coefficient of the torque converter, a clutch torque, and a hydraulic torque when the condition for operating the damper clutch protection logic is satisfied, determining whether a repetitive tip-in/tip-out that is intentionally performed occurs or not on the basis of a change in the slip power that is calculated in real time for a set time, and operating the damper clutch protection logic for restraining a slip of the damper clutch when there is the repetitive tip-in/tip-out that is intentionally performed.
