Definitions

  • the present invention relates to a method for the reduction of thermal loads and a method for cooling clutch systems, as well as a system therefor.
  • the components of the clutch especially the friction lining, have a limited temperature resistance, and the energy input is very high in relation to the available space, whereby the heat transfer to the environment is too low.
  • the pressure plate for example, has a smaller heat capacity in contrast to the flywheel of the clutch. Furthermore, the heat flow to the surrounding parts is relatively low and the heat transfer to the surrounding air within the clutch bell housing is also low. Thus, there is a limit relative to the operation of the clutch system as a result of the expected temperature rise in known clutch systems, especially of the pressure plate.
  • the object of the present invention is directed to a method and a system of the above-described type that makes possible the optimal cooling of a clutch system of a power train, so that the operating conditions of the clutch system in particular are improved.
  • the object of the invention is particularly achieved by providing a method for the reduction of the thermal load on a clutch system with which torque is transmitted.
  • the clutch system includes at least a pressure plate, a clutch disk, and a flywheel, whereby the frictional torque that exists at the time on the friction surfaces of the clutch disk is unevenly distributed.
  • the frictional load generated in the clutch system is determined by the frictional torque that acts and the relative speed.
  • an identical speed condition at both friction surfaces of the clutch disk is preferred.
  • a solution can consequently lie in producing uneven frictional torques on the respective friction surfaces.
  • the pressure plate for example, can be supplied with a smaller portion of the frictional energy that occurs, so that the thermal load is reduced.
  • a further embodiment can be provided in which different friction linings with different coefficients of friction can be utilized at the two friction surfaces of the clutch disk.
  • the frictional load that is produced is thereby introduced unequally to the two friction surfaces by providing different friction parameters at both frictional sides of the clutch disk.
  • the frictional torque that is generated depends on the effective friction radius, the contact pressure of the pressure plate, and the coefficient of friction of the respective friction surfaces. Influencing the clutch system coefficient of friction conditions provides the possibility to suitably distribute the thermal load. It is also conceivable that the other influence values could be changed.
  • a lower coefficient of friction can be utilized on the pressure-plate-side friction surface of the clutch disk than on the flywheel-side friction surface, so that a lesser amount of frictional energy is introduced on the pressure plate than on the flywheel. In that way, a desired distribution of the frictional load can be realized. Thereby, in an advantageous way, lower thermal loads arise on the pressure plate.
  • the respective friction partners on the flywheel-side are selected in such a way that a higher coefficient of friction arises when the temperature increases.
  • the clutch disk can have different friction linings on its two friction surfaces.
  • the friction partners on the flywheel-side have such a type of temperature dependence that a higher coefficient of friction arises with increasing temperature. If, as expected, a higher temperature arises at the friction point during the operation of the clutch, the coefficient of friction on the pressure plate side decreases, so that the desired coefficient of friction difference is adjusted.
  • the pressure plate and the flywheel can be made from combinations of the materials steel and aluminum.
  • the respective friction partners have such a temperature dependence that a lower coefficient of friction arises with increasing temperature, whereby a higher temperature exists on the pressure plate than on the flywheel, so that the desired coefficient of friction difference is realized.
  • a higher coefficient of friction is utilized on the pressure-plate-side friction surface of the clutch disk, for example, than on the flywheel-side friction surface if the pressure plate is suitably cooled.
  • a reverse friction load distribution is also conceivable.
  • a higher temperature of the pressure plate for example, can lead to an altogether better heat elimination at the clutch system by reason of a higher temperature differential.
  • a temperature-resistant friction lining must be utilized at each friction surface as the friction lining.
  • the underlying object of the invention is also especially achieved in that a method is proposed for cooling the clutch in a power train of a motor vehicle, in which a flow of cooling air for the clutch is utilized. Furthermore, particularly for carrying out the method, a system for cooling the clutch of a power train of a motor vehicle is proposed, wherein a flow of cooling air is provided that can be conducted through the clutch bell surrounding the clutch as a housing.
  • the already-existing air inlets of the motor vehicle for example for the ventilation of the interior, can be utilized as a cooling airflow to cool the clutch.
  • the flow of cooling air can be guided through the clutch bell that surrounds the clutch as a housing.
  • the inlets for example, could be designed and dimensioned accordingly. All together, the advantage of using already-existing air inlets is that, for example, filters, dirt pans, water drains, and the like, only have to be provided once in a motor vehicle because of their dual usage. In addition, by means of the air passages provided, acoustic advantages can be realized in contrast with open clutches.
  • the exiting cool air flow can be carried off to the environment using the existing exhaust gas system of the motor vehicle.
  • the cool air flow can thus be carried off through the exhaust gas system together with the exhaust gas.
  • the exhaust system is located near the transmission.
  • the cool air flow can be provided by a pump device provided in the exhaust gas flow of the exhaust gas system.
  • the cool airflow can thereby be drawn off through the clutch bell.
  • the pump device can especially be a jet pump, or the like, which is preferably provided in the exhaust gas stream. In that way, other necessary (active) cooling measures can be avoided.
  • the cool airflow is interrupted at least periodically through a shutter device in the exhaust system, so that an independent stationary exhaust gas measurement is made possible.
  • a shutter device in the exhaust system, so that an independent stationary exhaust gas measurement is made possible.
  • at least a flap, or the like can be utilized as a shutter device.
  • the proposed system and method can be utilized in high performance clutches, especially in a load-shift transmission (USG) and/or a double-clutch transmission (DKG).
  • USG load-shift transmission
  • DKG double-clutch transmission
  • FIG. 1 is a schematic view of a system for cooling a clutch with a jet pump
  • FIG. 2 is a graph with the results of a simulation calculation for a method for reducing the thermal load of a clutch.
  • FIG. 1 there is shown in FIG. 1 one possible embodiment of a system in accordance with the invention to cool a clutch, whereby an engine 101 with a connected exhaust gas system 102 , and a transmission 103 with a clutch bell 104 , as well as a drive shaft 105 , are shown in schematically.
  • an exemplary existing air inlet 107 for example for the windshield for ventilating the motor vehicle interior, which is utilized additionally for the cooling airflow in accordance with the invention.
  • Other air inlets can also be provided for the cooling airflow.
  • the cooling airflow can be withdrawn from the clutch bell 104 by means of at least one air outlet 108 through a jet pump 106 .
  • the jet pump 106 is located in the exhaust system 102 , and which is shown larger in the FIG. 1 enlargement portion.
  • the system in accordance with the invention by interconnection with the existing air inlet system and exhaust gas system provided in the motor vehicle, can enable the supply and withdrawal of the cooling airflow in accordance with the invention for the cooling of the clutch.
  • the system can especially be utilized in connection with a load-shift transmission (USG), a double-clutch transmission (DKG), and all types of high-performance clutches that require (air) cooling.
  • USG load-shift transmission
  • DKG double-clutch transmission
  • FIG. 2 there is shown the result of a simulation calculation for a method for reducing the thermal load on a clutch. There are shown therein different temperature trends over time.
  • the simulation model was prepared for a load-shift clutch of a USG system. In that way, the effect of the changed coefficients of friction can be shown.
  • the coefficients of friction of the respective friction surfaces are assumed, one time with a constant ratio (1:1) and one time with a ratio of 0.7:1.
  • a plurality of maximum accelerations of the motor vehicle to a speed of 100 km/h were assumed as the loading.
  • the upper curve of the pressure plate temperature TDP signifies the coefficient of friction ratio of 1:1, while the lower curve shows the pressure plate temperature T DP at the coefficient of friction ratio of 0.7:1.
