Coupling device e.g. multi-shed coupling device for use in gearbox of vehicle, has blade whose teeth are spaced apart radially with respect to groove portions by gap that forms portion of conduit portion

摘要

The coupling device (1) has a friction clutch (3) with several blades (4) which are arranged on a plate carrier (5). The blades and plate carrier are connected to each other through a spline. The blade is formed several teeth (10) supported on tooth portions (11) for torque transmission. The groove portions (12) are between toothed portions. A fluid conduit portion (13) for conducting fluid e.g. cooling oil, is formed between plate carrier and the blade. The teeth are spaced apart radially with respect to the groove portions by a gap (14) that forms portion of conduit portion.
