Embodiment Construction

[0026] figure 1 A connector system 100 is shown with a hydraulic connector 105 and a control device 110 . The connector 105 comprises an input side 115 and an output side 120 , which are rotatably mounted about a common axis of rotation 125 . Hydraulic fluid 130 represents the torque coupling between input side 115 and output side 120 . The input side 115 is supported relative to the output side 120 by means of at least one rolling bearing 135 . Depending on the type of coupling, in particular describing the coupling for the introduction and delivery of torque, the loads acting on the rolling bearings 135 can be different, even if their arrangement does not change. One or more seals 140 , which may contain different materials, may be arranged between the input side 115 and the output side 120 .

[0027] Connector 105 may exist in one of a variety of predetermined implementations. For example, connector system 100 may be used having connectors 105 of various predetermined d...

Abstract

The invention relates to a hydrodynamic clutch comprising an input side and an output side, the rotational motions of which are coupled to each other by means of a hydraulic fluid. The invention further relates to a method for determining the degree of filling of the hydrodynamic clutch with fluid, which method comprises steps of periodically sensing a fluid temperature of the hydraulic fluid; determining the rate of heat supplied to the clutch on the basis of the temperature; determining a lambda value on the basis of the rate of heat; and determining the degree of filling on the basis of thelambda value.

Description

technical field [0001] The invention relates to a hydraulic connector. In particular, the invention relates to the monitoring of hydraulic connectors. Background technique [0002] The hydrodynamic coupling is designed to transmit torque between the input side and the output side. For this purpose, the input side is connected to the pump wheel and the output side is connected to the turbine, wherein the pump wheel and the turbine are coupled to each other by means of a hydrodynamic fluid. If the coupling is operated with slip, for example during acceleration, so that the output side rotates at a different speed than the input side, the fluid is heated. If the temperature of the fluid exceeds a predetermined value, the load on the working machine must be reduced, or when reduction is not possible, the connector must be stopped and cooled. [0003] A method is known for predicting the expected temperature profile in the event of load changes based on the temperature of such...
