Definitions

  • the invention relates to a coolant circuit of an internal combustion engine with a first coolant pump and a second coolant pump driven by the internal combustion engine, the first coolant pump and the second coolant pump being connectable via a coupling.
  • a coolant pump with two axially aligned pump wheels is already known from DT 1476365.
  • the first pump wheel is firmly connected to the drive shaft.
  • the second pump wheel can be connected to the first pump wheel via a pressure-controlled coupling, the control pressure depending on the temperature of the liquid being conveyed.
  • the object of the invention is to design and arrange a coolant pump in such a way that optimum cooling of the internal combustion engine is ensured.
  • the object is achieved in that the clutch is assigned a transmission gear or that the clutch has a transmission gear or is operatively connected to a transmission gear.
  • the second coolant pump can thus be very small in accordance with the transmission ratio.
  • an additional possibility is that the first coolant pump and the second coolant pump are arranged in a common housing.
  • joint pre-assembly and, if necessary, a joint test run are possible.
  • the transmission ratio i of the transmission gear is between 0.05 and 0.9, in particular between 0.2 and 0.5.
  • the speed of the second coolant pump can thus be adjusted according to its size and the necessary delivery rate or cooling capacity.
  • a favorable operating point can be reached at the intersection of the motor characteristic and the pump characteristic.
  • the second coolant pump has a suction line and a pressure line, a check valve being provided within the suction line and / or within the pressure line.
  • the first coolant pump is positively and / or non-positively connected to the internal combustion engine or a separate motor.
  • the first coolant pump can also be provided with an electric motor or a pneumatic drive.
  • the ratio of the specific delivery capacity of the first coolant pump and the second coolant pump is between 1.5 and 10, in particular between 2 and 6.
  • the clutch is automatic and / or. has manually operable control part and the transmission ratio i of the clutch can be changed automatically and / or manually, the clutch being assigned a control element with a temperature sensor that detects the coolant temperature of the coolant in the cooling circuit.
  • the automatic control of the speed or the delivery rate ensures the use of a control unit that at least the coolant temperature and possibly. further parameters of the internal combustion engine such. B. takes the speed into account.
  • Fig. 1 is a schematic representation of a first
  • Coolant pump and a second coolant pump are provided.
  • the first coolant pump 1 shown in FIG. 1 has a pump shaft 1.3 and is driven by a pulley 6. On a side of the pump shaft 1.3 opposite the pulley 6, it is mechanically connected to a clutch 3.
  • the clutch 3 is a Assigned transmission gear 4, which translates the speed of the first coolant pump 1 to a higher speed.
  • the transmission 4 is infinitely variable, the transmission ratio i being between 0.2 and 0.8.
  • the clutch 3 or the transmission gear 4 is in turn mechanically connected to a second coolant pump 2 or to a pump shaft 2.4 of the second coolant pump 2.
  • Both coolant pumps 1, 2 are supplied with coolant via a common coolant supply line 7 and a suction line 1.1, 2.1, respectively. Via the pressure line 1.2 and the pressure line 2.2, the coolant is led into a common coolant channel -8 and from there to the internal combustion engine, not shown.
  • a check valve 2.3 is arranged within the suction line 2.1 of the second coolant pump 2.
  • the check valve 2.3 can also be provided within the pressure line 2.2 of the second coolant pump 2.
