ABSTRACT:
A drive shaft is connected with one coupling half of a synchronizing tooth clutch and with a primary part of a fluid coupling. A driven shaft is connected with another clutch half of the tooth clutch and with a secondary part of the fluid coupling. The tooth clutch has a clutch star which is axially displaceably guided by a first straight tooth system at the one clutch half by continuous tooth mesh and can be engageable with a second straight tooth system provided at the second clutch half. Threadably connected with the second clutch half a is also connected by a ratchet with the clutch star and is conjointly axially displaceable therewith. The ratchet engages and causes a screw-like relative movement of the screw socket in relation to the second clutch half causing of the clutch star to engage, when the rotational speed of the first clutch half, in normal forward rotation, is about to fall below the rotational speed of the second clutch half. This has advantage that for engaging the tooth clutch the rotational speed of the drive shaft need not drop below the rotational speed of the driven shaft. The time span, during which in synchronizing and engaging the tooth clutch power transmission, is interrupted is appreciably shortened. No special measures or facilities are required for protecting the ratchet.
