    摘要: A drive train has a hydrodynamic retarder including a rotating bladed rotor and bladed stator, forming a working chamber for hydrodynamic transmission of power from rotor to stator, a power input feeding drive power to the retarder, and a synchronized separating clutch connected between power input and rotor. The clutch has two clutch halves, friction elements contacting each other and mechanical blocking elements. The friction elements equalize rotational speed between clutch halves, and the blocking elements form-lockingly connect the clutch halves. The clutch has an actuator displaceable along a displacement travel, over a first distance bringing the friction elements into mutual contact, and a second distance adjoining the first distance to synchronize the friction elements and rotational speed for locking with the blocking elements. At least one displacement sensor directly or indirectly detects displacement travel by the actuator and/or position of the actuator on the displacement travel.
