Transmission control plate for electro-hydraulically operatable vehicle gearbox, has metallic functional layer provided with micro beads for formation of seal arrangement at side of transmission control plate for forming sealing lines

摘要

The plate (1) has passages (5) arranged correspondingly to a sample of a labyrinth structure. A seal arrangement is used to form sealing lines running along the labyrinth structure. A metallic functional layer (7) is provided with the passages corresponding to the sample of the labyrinth structure, and with micro beads (11) formed from a plane of the functional layer for formation of the seal arrangement at a side of the plate for forming the sealing lines. The functional layer includes a metallic carrier plate provided with a thickness within a range of 1-2 mm.
