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.

摘要： A cooling circuit for a motor vehicle having a cooling medium pump that circulates a cooling medium in the cooling circuit having a hydrodynamic retarder. The cooling circuit further includes a main circuit in which the cooling medium pump and a drive motor of the motor vehicle, as well as a heat exchanger are positioned. A secondary branch of the cooling circuit includes a feed that branches off from the main circuit at a branch-off point and ends in the hydrodynamic retarder, and a return which proceeds from the hydrodynamic retarder and ends at a junction location in the main circuit. The return ends upstream of the branch-off location of the feed as viewed in a flow direction of the cooling medium in the main circuit, however on the same side of the cooling medium pump or at the branch-off location of the feed in the main circuit.

摘要： The present invention involves a drive unit, specifically a drive unit for a motor vehicle having an internal combustion engine, a cooling system with fan and a hydrodynamic retarder with a stator, rotor and housing. The retarder is located within a space bounded on one side by the front of the crankcase, on a second side by the fan shaft which runs parallel to the engine shaft, and on a third side by the rear edge of the fan wheel. Viewed from the front, the retarder is substantially located within the fly circle of the fan wheel whereby the air flow generated by the fan wheel removes heat, generated by braking actions, from the housing of the retarder.
