A hydrodynamic clutch having an input side and an output side, the rotational motions of which are coupled to one another with a hydraulic fluid. A method for determining the degree of filling of the hydrodynamic clutch with fluid including steps of periodically sensing a fluid temperature of the hydraulic fluid, determining the thermal output supplied to the clutch on the basis of the temperature, determining a lambda value on the basis of the thermal output and determining the degree of filling on the basis of the lambda value.

Monitoring a hydrodynamic clutch

The invention concerns a hydrodynamic coupling, The invention is characterized in that the storage chamber is designed as a confined chamber which is pressure-tight to the environment, having a control pressure port so as to forcibly displace the working medium in the storage chamber with a control pressure.

Hydrodynamic coupling

The invention concerns a compression device fitted with a drive unit; with a compressor driven by the drive unit, which compresses a gaseous compression medium; with a cooling device, comprising at least one fan wheel, which cools the compression medium; the fan wheel is in drive connection with the drive unit or a second drive unit additionally provided, in order to be thereby driven in rotation. The invention is characterized in that a hydrodynamic clutch is arranged in the drive connection, via which the fan wheel is driven hydrodynamically, and the drive power transmission of the hydrodynamic clutch can be modified in operation by pressurizing the hydrodynamic clutch with a control pressure medium, wherein the compression medium is the control pressure medium at the same time.

Compression device and method for cooling a compression medium

The invention relates to a closure with a thermal safety function for a hydrodynamic or hydraulic machine, in particular a hydrodynamic clutch, designed for use in a housing of the hydrodynamic or hydraulic machine which holds a working medium, wherein the closure has a closure body for screwing or inserting into the housing or mounting on the housing in some other way; the closure body has a passage into which a closure core is introduced, which closure core is connected, by means of a melting element which can be melted on at a predefined temperature, directly to the closure body or to an intermediate element introduced in a seal-forming fashion in the closure body, in such a way that the passage is sealed off so as to prevent the working medium from passing through. The invention is characterized in such a way that the closure core has a blind bore or a blind hole which is open with respect to the working space, with the result that working medium can flow into the closure core.

Closure with thermal safety function for a hydrodynamic machine

The invention relates to a hydrodynamic clutch having constant or variable filling of work medium The hydrodynamic clutch is characterized in that the ratio of the volume of the work space to the installation volume of the hydrodynamic clutch is greater than 0.26, the installation volume of the hydrodynamic clutch being defined by a cylinder volume having constant diameter, whose external diameter corresponds to the maximum external diameter of the hydrodynamic clutch, and whose axial length corresponds to the maximum axial extension of the hydrodynamic clutch.

Hydrodynamic clutch

The invention relates to a hydrodynamic coupling having two blade wheels, namely, an outer wheel and an inner wheel, The hydrodynamic coupling also has a coupling shell. The invention provides that the inner wheel and the coupling shell each have one hole and the holes are situated on the hydrodynamic coupling and can be moved into positions that are aligned with one another when the inner wheel and the coupling shell are rotated. The hole of the coupling shell is larger than the hole of the inner wheel. A measuring pin for passing through the two holes.

A method for the supplying bearing elements in a hydrodynamic coupling: The coupling includes a primary wheel and a secondary wheel, which together form a working area capable of being filled with operating fluid. An operating fluid system having a direct circulation connecting at least one outlet from the working area to an inlet into the working area. A filling line connectable at least indirectly to the operating fluid source. An emptying line connecting the outlet at least indirectly to the operating fluid source. The filling line and the emptying line are connected via the direct circulation to the inlet and the outlet, together with a lubricant supply system, which is capable of connection to the filling line, and which is supplied with lubricant during all operating modes. At least during the filling mode, the supply of lubricant is via the filing line that is capable of connection to the operating fluid source. In the direct circulation functional mode of the operating fluid, the supply of the lubricant supply system between the outlet and the inlet is effected solely from the direct circulation.

A hydrodynamic machine with a turbo coupling comprising primary and secondary wheels together forming a torus shaped workspace, which can be filled with a working medium. A temperature-sensing device installed in a component, which rotates when the machine is operating, and sending a temperature &#x2014;dependant signal. A stationary monitoring device connected to the temperature sensor in a remote query connection, and having means for creating a temperature measurement correction depending on the heating rate progression of the sensed temperature.

Temperature-monitored hydrodynamic machine

The hydrodynamic coupling includes a pump blade wheel and a turbine blade wheel together forming at least one toroidal operating space capable of receiving an operating medium. The housing at least partially in an axial direction contains the pump blade wheel and forms an intermediate space at least with the pump blade wheel. The pump blade wheel defines at least one connection channel between the toroidal operating space and the intermediate space, the connection channel having at least one directional component that is oriented essentially tangentially to the contour of the circulation of the operating medium in the operating state between the pump blade wheel and the turbine blade wheel. The connection channel provides a partial flow of operating medium in the operating space, providing a rinsing effect for deposits collected on the housing in the intermediate space.

The invention relates to a hydrodynamic clutch ( ) comprising at least two impellers, as outer wheel ( ), and an inner wheel ( ). The inner wheel is equipped with an integrated synchronizer clutch ( ) and is enclosed by a clutch shell ( ) that is coupled to said outer wheel. The invention is characterized in that the clutch elements ( ) are formed by the inner wheel and by the clutch shell. Said inner wheel comprises at least two segments ( ) that are displaceably mounted in a radial direction.
