Definitions
- the invention relates to an operating medium for a hydrodynamic Machine, especially clutches and / or brakes.
- Hydrodynamic machines such as, for example, are customary Clutches or brakes (see Voith, hydrodynamic gears, Clutches, brakes, Otto Krausskopf-Verlag GmbH, Mainz, 1970, their Full disclosure content in the present application is included) filled with mineral oils as the working fluid. This had the The advantage that the bearing lubrication is always ensured by the mineral oils.
- G 84 14 929 proposed by the Provide surfaces in contact with the working liquid with a metal oxide layer.
- glycol or phosphate ester was used as an alternative to water as the operating medium to meet the demand for low environmental impact and Flame retardant.
- glycol as the operating medium, a simultaneous lubrication of the bearings can be guaranteed, but resulted problems in the area of environmental pollution when using this substance. So Depending on the manufacturer, glycol can be classified in Water hazard class 0 or 1 can be obtained, despite the classification in Water hazard class 0 is the use of this operating medium especially difficult in water protection areas, because the liquid is a has a higher density than water and is also water-soluble.
- a high hydrodynamic torque transmission is said as well as the bearing lubrication are guaranteed.
- the Bearing lubrication should last with the new operating medium as can be achieved with the use of mineral oils.
- the working fluid has a high thermal load and the formation toxic substances under temperature stress can be excluded. Is solved this task by the operating medium specified in claim 1, the characterized in that it comprises fully synthetic esters.
- Fully synthetic esters made from mineral oil are particularly preferred synthesized dicarboxylic esters and / or polyol esters.
- this Operating medium according to the invention has a flash point that> 280 ° C. is.
- the operating medium according to the invention is easily biodegradable, should leak from the closed circuit due to leakage etc.
- the hydraulic fluid has sufficient ecological compatibility and is in water hazard class 1 (classification according to the VCI concept) only weakly water-hazardous, classified.
- a turbo coupling becomes a working medium specified, which is characterized by high fire safety and a high environmental compatibility and all for use in turbo couplings necessary technical operating conditions are met.
