A jaw or dog clutch which automatically engages when reaching rotational speed equilibrium possesses an axially displaceable clutch star which is rigidly connected for rotation by means of a first tooth system or set of gear teeth with a drive hub, however, is connected to be axially displaceable, and possesses a second tooth system or set of gear teeth which can be brought to mesh, by axial displacement of the clutch star, with a tooth system or set of teeth, of a power take-off hub. At the clutch star there is rotatably mounted a screw socket which is connected by means of a pair of coarse-pitch threads with the power take-off hub. The screw socket can be entrained in one rotational direction by the clutch star by means of a pawl blocking device. A bearing, by means of which the drive hub and power take-off hub bear upon one another, is arranged radially within the screw socket and forwardly of the remaining parts or components of the jaw clutch to be lubricated located in a channel system where lubricant flows through the jaw clutch under the influence of centrifugal forces. Thus, in all of the operating conditions there is realized, with as low as possible total throughput of lubricant, a sufficient lubrication of all of the components of the jaw clutch.
