Definitions

  • the invention relates to a pump, a clamping element and a motor.
  • An engine is typically equipped with a cooling system that includes a coolant pump configured to deliver coolant within the cooling system.
  • the coolant pump is for this purpose driven by a chain or a belt of the engine.
  • the inventive pump according to claim 1 is designed for coolant delivery in a motor.
  • a clamping element which is designed for clamping a drive member of the motor integrated.
  • a functional integration pump for delivering coolant in a cooling system of the engine or an internal combustion engine is provided.
  • the drive member which wraps around in the engine a number of waves and is also designed to drive the pump, can be tensioned with the clamping element of the pump. With the clamping element length changes that occur during operation of the drive member can be compensated.
  • the clamping element can be inserted in a pump housing of the pump.
  • the clamping element can also be formed as an integral part of the pump, preferably of the pump housing.
  • a recording of the clamping element in the pump can be realized for example by a hydro element. If the clamping element is inserted in the pump housing, then it is provided that this is supplied by a main oil passage of the engine with pressurized oil.
  • a shaft of the pump, which is connected to a drive wheel, wherein this drive wheel is rotated by the drive member is mounted in a preferably hydrodynamic sliding bearing.
  • This slide bearing is lubricated by a first bore which is connected to the main oil passage.
  • This first bore within the pump housing connects the main oil passage of a cylinder crankcase of the engine with a secondary oil passage of the pump.
  • the pump can be designed as a coolant pump or as a water pump.
  • the drive member is then formed as a component of a Primär Kunststofftriebs the engine.
  • This drive member may be formed as a chain, belt, in particular toothed belt, V-belt or flat belt.
  • the pump preferably has a shaft which is mounted on the slide bearing. At one end of the shaft is usually located a drive wheel, which cooperates with the drive member, so that the shaft is rotated via the drive wheel during operation of the motor in a rotational movement.
  • a closed impeller In the pump with the integrated clamping element can also be integrated a closed impeller.
  • This closed impeller is preferably fixed to another end of the shaft, rotates with the rotating shaft and thus provides a promotion of a volume flow of the coolant necessary for cooling the engine.
  • the inventive pump according to claim 9 is designed for coolant delivery in a motor.
  • a closed impeller is integrated.
  • the closed impeller is easy to manufacture.
  • the pump is preferably formed as part of a cooling system of the engine.
  • the rotating impeller can be flowed axially by the coolant or a cooling liquid.
  • a disc may be arranged at a back of the impeller.
  • a mechanical seal presses this disc against the impeller.
  • the impeller can thus urgeformt be prepared without further processing.
  • the gap can be very easily and accurately realized by a cylindrical machining in a cylinder crankcase of the engine, whereby a gap situation in the pump is optimally designed.
  • the closed impeller in the pump is easy to install.
  • the shaft is mounted radially via a preferably hydrodynamic slide bearing, said slide bearing is supplied by a main oil passage from a cylinder crankcase of the engine with pressurized oil.
  • a cost-effective storage can be provided for the shaft of the pump.
  • a fitting of the closed impeller to the pump housing is improved.
  • waves in such pumps are axially sealed, which can result in a problematic axial play of the shaft. This is avoided in the present pump by a radial seal for radial sealing of the shaft.
  • a drive wheel or impeller of the pump may be driven by the drive member from the primary control drive of the engine.
  • the pump has, for example, a spiral geometry and is cast in a V-shaped space of a cylinder crankcase of the engine.
  • the impeller and the drive wheel can be screwed by a thread against a rotational direction of the shaft during operation of the pump, depending on whether clockwise or counterclockwise, on the shaft.
  • the pump for delivering the coolant within the cooling system is usually driven mechanically via a toothed or poly-V belt or chain as a drive member.
  • the integrated in the pump according to the invention clamping element biases the drive member of the motor in a suitable for a respective Hetriebsituation measure.
  • the drive member is sufficiently taut in all operating conditions of the engine, so that between the individual wheels of waves of the motor, which wraps around the drive member, rotational movements can be effectively transmitted.
  • the motor according to the invention may comprise a drive member and the pump according to the invention according to one of the possible embodiments. Accordingly, the drive member of this motor cooperates with at least one component of the pump.
  • This at least one component of the pump can be designed as the clamping element integrated in the pump, so that the drive member cooperates with the clamping element, and / or as the pump wheel integrated in the pump, so that the drive member interacts with this pump wheel.
  • the pump housing 3 additionally has circumferential grooves 9 for receiving O-rings.
  • a disc 12 on the back of the closed impeller 6 is pressed by a mechanical seal 14 against the closed impeller 6. This makes it possible to dispense with a mechanical connection between the disk 12 and the closed impeller 6. Furthermore, the closed impeller 6 can be prepared by arrangement of the disc 12 as urgeformt and without further processing.
  • the pump housing 4 with a pump element 16 has a first bore 18, a relief bore 20 and a second bore 22.
  • a gap of the closed impeller 6 can be very easily and accurately represented by a cylindrical machining in the cylinder crankcase 25.
  • the bearing of the pump shaft 10 takes place radially via the preferably hydrodynamic slide bearing 26, which is supplied by a main oil passage 28 from the cylinder crankcase 25 via the second bore 22 shown in Figure 2 with pressure oil.
