摘要： A method for controlling a hydrodynamic machine, including the steps of: providing a hydrodynamic machine which includes a bladed primary wheel and a bladed secondary wheel, which together form a working chamber, which can be filled with a working medium from a working medium supply contained in a working medium reservoir, to transfer drive power hydrodynamically from the bladed primary wheel to the bladed secondary wheel by forming a working medium circuit in the working chamber; applying a control pressure to the working medium supply in order to force the working medium from the working medium supply into the working chamber; detecting, at least indirectly, a pressure increase in the working medium reservoir, when the control pressure is applied to the working medium supply; and determining, as a function of the pressure increase that has been detected, a fill level of the working medium supply in the working medium reservoir.

摘要： A method for controlling a hydrodynamic retarder in a motor vehicle that can be mechanically disengaged via a disconnect clutch, comprising a drive motor whose power output is controlled via an actuator such as a foot pedal or a lever; whereby in an overrun operation the acceleration of the motor vehicle is collected or detected and compared with a pre-specified acceleration value; and whereby in the non-braking mode the disconnect clutch is engaged, regardless of an initiation of a braking mode by an operator of the motor vehicle or a driver assist system and the working chamber is maintained drained when the acceleration exceeds an acceleration limit.

摘要： A hydrodynamic retarder having a rotor and a stator or a rotor and an oppositely running rotor, which together form a toroidal working chamber to filled with working medium, in order to transmit a torque by means of a hydrodynamic working chamber working medium circuit. An external working medium circuit has a heat exchanger that discharges heat from the working medium. The external working medium circuit is connected by a working medium inlet and a working medium outlet to the working chamber. The working medium inlet and outlet open to the working chamber at a torus outer diameter of the working chamber. A working medium feed line opens into the external working medium circuit. A core ring filling line is connected in working-medium-conducting fashion to the working chamber. The core ring filling line opens into a core ring of the working chamber radially within the torus outer diameter.

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： The invention concerns a method for controlling a vehicle drive train with a hydrodynamic retarder which can be engaged and disengaged mechanically via a coupling, whereas the retarder comprises a working chamber formed between two bladed wheels, which is filled with a working fluid for generating a braking torque after detecting a retarder switch-on signal and is emptied of the working medium after detecting a retarder switch-off signal to turn off the braking torque, and the retarder is driven in braking mode by means of a drive shaft via the closed coupling to constitute a hydrodynamic circuit of the working fluid in the working chamber.The invention is characterised in that the speed of the vehicle and/or the rotational speed of the drive shaft is detected or calculated and the coupling is closed above a preset limit speed and/or above a preset limit rotation speed independent of the detection of a retarder switch-on signal to drive the retarder.
