| 摘要 |
The invention relates to a slip friction clutch (4), especially a torque converter lockup clutch for a hydrodynamic torque converter in an automatic gearbox of a motor vehicle, comprising at least one pair of wet-running friction surfaces. Both friction surfaces, when pressurized, seal the radially outer high-pressure pressurization chamber against the radially inner low-pressure pressurization chamber. At least one of the friction surfaces has oil conducting recesses (8-11) whose two ends are distanced from each other and are directly hydraulically connected to one of the two pressurization chambers. Said recesses are embodied in such a way that when slip friction coupling occurs, the friction surface which slides in a peripheral direction has a tractive effect, causing oil to flow through as a function of the slip speed, thereby enabling the friction surface to be cooled. |
