Abstract
A Shift fork is provided for shifting gears of a transmission assembly of a gear box that includes, but is not limited to a basin for collecting splash oil. The basin includes, but is not limited to an outlet channel for guiding the collected oil away from the basin. By means of the basin splash oil can be collected and led via the outlet channel to nearly every place of the transmission assembly, where additional lubrication is wanted. This provides a better lubrication of parts of the transmission assembly with low effort.

- at least one transmission shaft comprising at least one moveable gear wheel of a gear;
- and
- a shift fork shifting the gear, the shift fork comprising:
- a basin collecting splash oil;
- and
- an outlet channel of the basin guiding the splash oil away from the basin,
- wherein the at least one transmission shaft is born by a first bearing and a second bearing,
- wherein the first bearing is located closer to the basin of the shift fork than the second bearing, and
- wherein a central opening is adapted for leading the oil collected by the basin to the second bearing inside an actuating shaft of the shift fork.
