Definitions

  • the invention relates to a controllable provided with a pulley Coolant pump for internal combustion engines.
  • Eliminating coolant pumps are adjustable in the prior art a pulley driven by the crankshaft coolant pumps Internal combustion engines described above. Generally for these designs characteristic that the maximum speed of the impeller of the maximum Speeds of the pump shaft driven by the crankshaft corresponds.
  • This maximum speed of the impeller offered by the crankshaft can be regulated, regulated, coolant pumps driven by the crankshaft, with the various technical means can be reduced.
  • JP 62-210287 A and DE 197 01 describe it 993 A1 different designs of adjustable, via a pulley driven coolant pumps, which use different designs of switchable magnetic clutches depending on the Operating temperature of the coolant, a connection between the impeller and manufacture the pulley.
  • V-belt side is very large, but also adjustable, adjustable coolant pump due to contamination one driven by a pulley and a backstop Impeller with switchable electric motor presented.
  • the pulley and the stator of the electric motor are in this design connected to each other and via the backstop to the pump shaft coupled.
  • the rotor of the electric motor is at the outer end of the pump shaft firmly connected to the pump shaft and designed as an external rotor.
  • the invention has for its object one with a pulley to develop a provided, controllable coolant pump for internal combustion engines, which does not have the aforementioned disadvantages of the prior art, is not susceptible to faults, and the function of Auxiliary heating pumps and / or post-heat pumps can take over, at the same time an increase in the conveying capacity in the hot idle state, as well enables an increase in the heating flow at low speeds, also better engine temperature control while saving energy causes the engine warm-up phase and reduces pollutant emissions lowers.
  • this object is achieved by an adjustable, with a Pulley, a switchable electric motor and a backstop provided coolant pump with the features of the main claim of Invention solved.
  • Impeller diameter significantly reduced the warm-up phase of the engine be so that the pollutant emissions of the engine in the warm-up phase sinks.
  • the pump function even before the Engine start as well as after the engine stop are guaranteed. This can when using the coolant pump according to the invention, for example There is no need to install separate auxiliary heating pumps and / or post-heat pumps.
  • the delivery rate can be achieved by means of the arrangement according to the invention Coolant pump increased as required, for example when hot idle become.
  • the solution according to the invention also makes it possible to increase the Heating flow at low speeds, for example in the case of traffic jams optimal heating of the passenger compartment on wintry motorways guarantee.
  • the pump shaft drives the coolant pump which is in the Coolant pump integrated electric motor is switched off and works as Generator.
  • motor electronics in the pump housing to control the integrated in the coolant pump, as a motor and as Generator working, electric motor is arranged.
  • the sleeve naturally also at the same time can be designed as a hub of the backstop, whereby in addition to the Size especially the manufacturing costs of the invention Coolant pump can be reduced.
  • Coolant pump with a stored in a pump housing 1, with a Pulley 3 provided pump shaft 2 is characterized in that on the opposite of the pulley 3, the bearings in The area of the pump shaft 2 protrudes in the direction of the flow space Backstop 7 is arranged.
  • Pinch roller backstop trained backstop 7 is a non-rotatable the pump housing 1 projecting sleeve 8 is arranged.
  • This brushless small motor integrated in the coolant pump whose Power consumption, for example, can only be approximately 30 to 50 watts enables the use of the controllable coolant pump according to the invention even with 12 V electrical systems.
  • the inventive, between pump shaft 2 and impeller 11th arranged, acting against the direction of rotation of the impeller 11 Backstop enables that to be effective due to the impeller direction of rotation becoming freewheel in conjunction with that on the backstop arranged electric motor, in addition to one even when the engine is stopped guaranteed pump function, even when driving, the speed of the Electric motor, for example in the range of small to medium speeds, the Overhaul the speed of the pump shaft driven by the crankshaft can, so as to ensure an increased coolant throughput if necessary.
  • the one integrated in the coolant pump switches Electric motor and works as a generator.
  • the also integrated in the pump housing 1 of the coolant pump Motor electronics 13 takes over the control of the The electric motor.
  • the pump shaft 2 of the coolant pump is by means of a plain bearing 4 and one of the pulley 3 arranged adjacent Rolling bearing 5 stored.
  • the sleeve 8 projecting end of the pump shaft 2 is one Lock washer 12 arranged.
  • This locking washer 12 is on the Sleeve 8 on and serves an exact in the operating state of the coolant pump Positioning the sleeve 8.
  • auxiliary heating pumps and / or post-heat pumps can assume the additional installation of separate Avoids electric pumps for auxiliary heating and / or afterheating, one Increased output in hot idle state, as well as an increase in Heating flow at low speeds,
  • the solution according to the invention allows a significant reduction of the impeller diameter compared to conventional designs of Coolant pumps.
  • the reduced impeller diameter is necessarily smaller Flow volume flows at partial and full load result and especially in the high speed range, that less "excess amount” volume flow is generated so that by the invention Reduction of the impeller diameter and better engine temperature control is guaranteed.
