Embodiment Construction

[0032] figure 1 A schematic diagram of a coupling system 100 with a fill-controlled fluid coupling 105 is shown. The coupling 105 is designed for controllably transmitting a rotational movement between an input side 110 and an output side 115 , which are mounted rotatably relative to each other about a common axis of rotation 120 . The coupling 105 includes a pump wheel 125 connected to the input side 110 and a turbine wheel 130 connected to the output side 115 . The pump wheel 125 and the turbine wheel 130 form a working chamber 135 in which a fluid 140 can be accommodated in order to hydraulically couple the turbine wheel 130 to the pump wheel 125 . In this case, the degree of coupling is related to the quantity of fluid 140 contained in the working chamber 135 . Pump wheel 125 and turbine wheel 130 are generally rotatably mounted by means of bearings 145 . For supplying the bearing 145 with fluid 140 a lubrication line 150 is provided. Fluid 140 may include aqueous or o...

Abstract

A filling-controlled hydrodynamic coupling comprises a pump wheel and a turbine wheel which delimit a working chamber and which can be mechanically coupled to one another by means of a hydraulic fluid; a direct circuit, which connects a hydraulic outlet to a hydraulic inlet of the working chamber; a pump device, which is arranged hydraulically between a fluid source and the direct circuit; and a lubrication line, which leads from the pump device to a lubrication point of the coupling. Here, the pump device is designed to convey fluid in a first conveying direction from the fluid source into the working chamber and into the lubrication line or in a second conveying direction from the working chamber to the fluid source.

Description

technical field [0001] The invention relates to a hydraulic coupling, which is also called a hydraulic coupling or a turbo coupling. In particular, the invention relates to a fill-controlled fluid coupling with direct circulation. Background technique [0002] The fluid coupling is designed to transmit torque between the input side and the output side. The input side is connected to the pump wheel and the output side is connected to the turbine, which delimit the working chamber. If the working chamber is filled with fluid, a hydrodynamic coupling occurs between the input-side and output-side rotational movements. In controlled fill couplers, the degree of coupling can be influenced by the amount of fluid in the working chamber. Usually, a filling pump is provided in order to deliver the fluid into the working chamber. A part of the transported fluid is shunted and directed to the lubrication points, especially the rolling bearings supporting the pump wheel or turbine. ...
