Definitions

  • Lubricant quantities are required by a low Zielboxvolumenstrom is driven in these work areas.
  • a shortage supply can be avoided if, for example, at high temperatures a significantly larger amount of cooling oil is taken into account in the pump control.
  • the supply arrangement comprises a primary hydraulic circuit I for supplying transmission components, such as switching elements A, B, C, D, E and a converter clutch WK and a parking brake device PS.
  • a primary hydraulic circuit I for supplying transmission components, such as switching elements A, B, C, D, E and a converter clutch WK and a parking brake device PS.
  • the switching elements A to E are supplied hydraulically in order to put these on or can.
  • the converter clutch and the parking brake device PS are supplied with hydraulic fluid for engagement or disengagement with the insertion pressure Pein and the deployment pressure Paus.
  • a detection device S is provided for detecting the current hydraulic fluid volume flow in the secondary hydraulic circuit II.
  • the detection device S comprises, for example, a sensor for detecting the pressure or the volume flow, wherein the detection device S is arranged in the flow direction behind the cooling device K in the secondary hydraulic circuit II.
  • the adaptation of the delivery volume flow of the pump P takes place via a control system consisting of the primary hydraulic circuit I to supply the switching elements AE and the actuators and the converter clutch WK and the parking brake device PS, the secondary hydraulic circuit II to supply the Geretekühl- and lubrication systems and the Tertiary hydraulic circuit III.
  • the detection device E comprises a sensor for detecting the volume flow or a defined dependent variable in the secondary hydraulic circuit II.
