Jaw Clutch

The invention relates to a dog clutch (10) with an axially fixed coupling element (12) and an axially movable coupling element (14), in which the axially fixed coupling element (12) and the axially movable coupling element (14) are configured to be sleeve-shaped and are disposed coaxially to one another, in which the axially movable coupling element (14) is axially displaceable by means of a pressurizing medium-actuatable piston (22) to establish a positively locking connection with the axially fixed coupling element (12), in which the piston (22) is disposed in a longitudinally displaceable manner in a cylinder housing (20), which radially on the outside carries the axially movable coupling element (14), in which the piston (22) is connected to the axially movable coupling element (14) via a piston pin (26), and in which a pressurizing medium (40) can be supplied to the cylinder space (60) of the cylinder housing (20) via a supply duct (38), wherein, at one axial end, the piston (22) is permanently connected to a coaxially aligned sensor bolt (48) and, on a sensor section (52) in the area of its free, piston-remote axial end (78), the sensor bolt (48) is configured as a transmitter element for a position sensor (70).
