摘要:
The present invention is a drive system for a boat propeller, with a motor and a reverse gearbox. For forward travel a hydrodynamic coupling is provided and for reverse travel a hydrodynamic reverse converter is provided. The coupling is operated with its maximum filling degree in the upper range of the propeller speed, but in the lower range of propeller speed with a partial filling. Thus, the hydrodynamic coupling is the single hydrodynamic power transfer unit for the entire forward speed range. In order for the boat to be able to be quickly braked down from full speed, the reverse converter is arranged to provide a high torque conversion in the reactive braking range.

A vehicle cooling circuit, especially an engine cooling circuit, including a cooling medium pump and a vehicle drive engine and/or other heat-generating assembly cooled by means of the cooling medium. The circuit includes a hydrodynamic retarder with the working medium of the hydrodynamic retarder simultaneously also being the cooling medium of the cooling circuit, and the hydrodynamic retarder operating as the cooling medium pump. The secondary blade wheel is associated with a brake or a drive running counter to the drive of the primary blade wheel in such a way that it can optionally be fixed in a first operating state (braking operation) or be driven counter to the rotational direction of the primary blade wheel and, in a second operating state (pumping operation), can partially or completely be released such that it circulates at the speed of the primary blade wheel or at a specified speed difference slower than the primary blade wheel.

The invention relates to a hydrodynamic machine, in particular hydrodynamic retarder, with a bladed primary wheel, which is rotatable over an axis of rotation of the hydrodynamic machine, and a bladed secondary wheel which is stationarily or rotatable over the axis of rotation of the hydrodynamic machine, wherein the primary wheel and the secondary wheel together form a toroidal working space which is filled or can be filled with working medium, and the primary wheel has at least one inlet channel for the working medium. The invention is characterised in that the inlet channel runs within the torus wall and/or within a blade of the primary wheel and opens in the region of the centre or radially outside the centre between the outer radius and the inner radius of the blades of the primary wheel at a location in the region of the torus wall in the working space.

The invention relates to a method for control of a pressurised air supply system for a motor vehicle (10), said system comprising a drive motor (1) for driving the motor vehicle, which drives an air compressor (3) by means of a drive connection (2), or said drive connection for driving the air compressor may be switched on. Said method comprises the following method steps: in a supply condition, the air compressor is driven by the drive motor and connected with the air supply side (3.1) thereof to a compressed air system (5) of the motor vehicle (10), such that compressed air is supplied to the compressed air system, in a non-supply condition, the air compressor is not driven and/or is not connected to the compressed air system, whereby the switching of the supply or non-supply condition is carried out on the basis of a comparison of at least one switch pressure value with a pressure (25) in the compressed air system (5) and the topography of the stretch of road (11) on which the motor vehicle (10) is travelling is recorded, said topography includes the profile of the path (12) which the vehicle (10) must cover within a directly following period of time and/or path distance to a given destination. At least one switch pressure value (20,30) is fixed on the basis of the determined topography.

The invention relates to a lockup clutch (1) for hydrodynamic components (2), comprising at least one primary wheel (4) and one secondary wheel (5), which define a working chamber (6), and having two inputs (26, 27)—a first input (26) linked to the secondary wheel (5) and a second input (27) linked to the primary wheel (4). Said inputs (26, 27) can be optionally linked to an output (28) of the lockup clutch (1) via a switchable clutch, thereby producing a first or a second power branch (32, 33). The coupling between the input (27) of the lockup clutch (1) that is coupled to the primary wheel (4) and the output (28) of the lockup clutch (1) in order to create the second power branch (33) is free of any rotationally fixed mechanical connection between the primary wheel (4) and the secondary wheel (5). The coupling between the inputs (26, 27) of the lockup clutch (1) and the output (28) of the lockup clutch (1) in the individual power branches (31, 33) is provided with rpm/torque converting devices.
摘要:
A retarder with retarder housing for receiving a retarder unit comprising a stator and a rotor fitted on the retarder shaft. The retarder is intended for assembly in a transmission housing. The retarder housing features a cup-shaped recess matching in its design the outer contours of rotor and stator, (a preassembled retarder unit) thus being able to receive the retarder unit in an assembled state.
