摘要： The invention relates to a hydrodynamic machine, in particular a hydrodynamic retarder, comprising a bladed impeller and a bladed turbine which together form a toroidal working chamber that can be filled with a working fluid in order to produce a hydrodynamic circuit flow for transmitting a drive torque, at least the bladed impeller or at least the bladed turbine being driven by a drive shaft of the hydrodynamic machine via an axis of rotation. The hydrodynamic machine also comprises a side-channel pump having a pump impeller with a plurality of pump blades and a channel running in the circumferential direction of the pump impeller, said channel having an inlet end and an outlet end. The pump blades are arranged in the channel or opposite the channel such that when the pump impeller rotates, a conveying effect is created in the channel in such a way that a suction effect is produced at the inlet end and a pressure effect is produced at the outlet end. The inlet end or the outlet end form a conductive connection for the working fluid with the working chamber. The hydrodynamic machine according to the invention is characterised in that the pump impeller is supported radially on the drive shaft in a rotationally fixed manner such that it can be moved axially and/or tilted at an angle.

摘要： The invention relates to a method for controlling a vehicle power train with a hydrodynamic retarder which can be mechanically engaged and disengaged via a clutch. The retarder has a working chamber which is formed between two bladed wheels and which is filled with a working medium in order to generate a braking torque after a retarder switch-on signal is detected and emptied of the working medium in order to cancel the braking torque after a retarder switch-off signal is detected. During a braking operation, the retarder is driven by means of a driveshaft via the closed clutch in order to form a hydrodynamic circuit of the working medium in the working chamber. The invention is characterized in that the speed of the vehicle and/or the rotational speed of the driveshaft is detected or calculated, and the clutch is closed above a specified threshold speed and/or above a specified threshold rotational speed regardless of the detection of a retarder switch-on signal in order to drive the retarder.

摘要： The invention relates to a method for controlling the power transmission of a hydrodynamic retarder, comprising a circulating rotor having vanes and a stator having vanes or a counter-rotating rotor having vanes circulating in the opposite rotational direction to the rotor, which together form a working chamber that can be filled with operating medium by means of an inlet and that can be emptied by means of an outlet, wherein the working chamber is filled in a brake operation with operating medium and a brake torque is generated with the hydrodynamic retarder and, in a non-braking operation, the working chamber is emptied to a specific residual amount of operating medium and substantially no brake torque is generated with the hydrodynamic retarder. The invention is characterised by the following step: In the non-braking operation, by means of an idling pump, operating medium is conveyed from an operating medium reserve, which is provided outside the working chamber in an operating medium reserve tank, into the working chamber of the hydrodynamic retarder for the adjustment of the residual amount.

摘要： The invention relates to a drive train, in particular of a motor vehicle having a drive engine, comprising a main output shaft by means of which drive wheels or another assembly can be driven; having a hydrodynamic retarder comprising a driven bladed primary wheel and a bladed secondary wheel which is fixed or driven in the opposite direction to the primary wheel, said wheels forming with one another a toroidal working space which is filled or can be filled with a working medium, in order to transmit torque hydrodynamically from the primary wheel to the secondary wheel; the drive engine has a secondary output shaft by means of which the primary wheel of the retarder is driven. The invention is characterized in that the hydrodynamic retarder is embodied as a single-stage, uncontrolled retarder which can be switched exclusively between a switched-on state and a switched-off state.

摘要： The invention relates to a brake system, in particular for a motor vehicle, comprising an external working-medium circuit and a hydrodynamic retarder that includes a bladed rotor and a bladed stator, which together form a toroidal working chamber, which can be filled with working medium from the external working-medium circuit through an inlet, wherein said working medium is conducted back into the external working-medium circuit through an outlet. The brake system further comprises a storage chamber for accommodating working medium that is currently not located in the working chamber or circulating in the external working-medium circuit and comprises a pressurization system for applying a control pressure to the working medium contained in the storage chamber so that more or less working medium is forced into the working chamber in order to set a desired braking torque. The invention is characterized by a throttle valve connected downstream of the outlet and including a movable or deformable valve body in order to vary the flow cross-section for working medium from the working chamber, wherein the valve body is exposed to working-medium pressure from the working chamber of the hydrodynamic retarder in the opening direction of the throttle valve and to the control pressure or a pressure dependent on the control pressure in the closing direction.

摘要： The invention relates to a power train for a motor vehicle, in particular a truck, comprising a hydrodynamic retarder (10) which can be mechanically connected to a driveshaft (1) in a driving manner and disengaged from said driveshaft by means of a disconnect clutch (14). The hydrodynamic retarder (10) is positioned on a speed-boosting shaft (9) in a speed-boosted mode relative to the driveshaft (1), said speed-boosting shaft being connected to the drive shaft (1) via a speed-increasing ratio. The invention is characterized in that the speed-increasing ratio is designed in at least two steps and comprises an intermediate shaft (5) on which the disconnect clutch (14) is positioned. A first gear step (3) is provided between the driveshaft (1) and the intermediate shaft (5), and a second gear step (7) is provided between the intermediate shaft (5) and the speed-boosting shaft (9). The hydrodynamic retarder (10) and the disconnect clutch (14) are positioned either together between the first (3) and the second (7) gear step or together on the first (3) gear step side facing away from the second (7) gear step or together on the second (7) gear step side facing away from the first (3) gear step with respect to the axial direction of the drive shaft (1).
