Snap-action connection for two drum parts, especially for a hydraulically activated double friction disc clutch in a motor vehicle automatic transmission

摘要

A snap-in connection for two drum components, in particular for a hydraulically actuated friction disk double clutch of an automatic transmission for motor vehicles, with two sets of friction disks, one of which with its outer circumferences rotatably on the inner circumference of one drum component and with its inner circumferences on the outer circumference of a clutch carrier part in each case between one The stationary pressure plate and an annular piston arranged in a ring cylinder can be actuated hydraulically and a cup-shaped drum component is connected radially and axially fixedly, but releasably if necessary, to another cup-shaped drum component, the latching connection consists of a circumferential latching groove (25) formed on a drum component (8) ) or two locking recesses and two locking cams (26) offset by 180 degrees and projecting radially inwards on the other cup-shaped drum component (22), and the cup-shaped drum components (8 and 22) are locked by axially pressing on, with oval expansion of the one drum component (22) in the elastic range.
