Bridging device for hydraulic torque transmission device i.e. torque converter, has clutch disk with two channels connecting area on radial inner side with areas axially formed between front cover and clutch area and piston and clutch area

摘要

The device has a clutch disk (80) with a friction clutch area axially arranged between a piston (75) and a front cover (11) for friction contact with the piston and the cover. The disk has two channels (P1, P2) that are formed within the disk and connects an area (S1) on a radial inner side with an area that is axially formed between the cover and the clutch area and an area (S2) on the radial inner side with an area that is axially formed between the piston and the clutch area, respectively. The disk is formed from two plates and intermediate plates (81, 82, 83).
