Abstract
The invention relates to a hydraulic transmission valve with a magnetizable housing which is integrally configured in one piece with a pole core cone. The transmission valve according to the invention facilitates comfortably coupling in particular startup clutches, shifting clutches or synchronization clutches in a friction locking manner. Still using a transmission valve of this type is facilitated for fewer to no transmission oil changes. Furthermore a transmission valve of this type can also be used in countries with inferior transmission oil quality. The housing includes a connection. The connection defines an anchor stroke and a concentric arrangement between the pole core cone and a pole tube. Thus, the pole tube is fixated the magnetizable pole flange. An anchor that is exclusively supported in the pole tube is magnetically separated from the pole tube through a separation layer with a thickness of 0.01 mm to 0.06 mm.
