Definitions

  • the invention relates to a controllable pump for an internal combustion engine having a drive wheel, a drive shaft which is drivable via the drive wheel, a Kupplungspumpenrad with pump blades, which is non-rotatably mounted on the drive shaft, a Kupplungssturbinenrad with turbine blades, which is rotatably mounted on the drive shaft, wherein the turbine blades are arranged axially opposite to the pump blades and a delivery wheel which is fixedly connected to the Kupplungsturbinenrad.
  • various pumps such as coolant pumps, oil pumps or vacuum pumps are coupled via belt or chain drives with the crankshaft of the internal combustion engine, so that no additional drive units are necessary.
  • hydrodynamic coupling which works according to the Föttinger principle.
  • the function of this clutch is based on the fact that between a driven Kupplungspumpenrad and an opposite Kupplungsturbinenrad, the movement of the impeller is transmitted by the dynamics of the arranged between the wheels fluid to the Kupplungsturbinenrad. The less fluid that can flow out between the two wheels, the greater the transmission of the torque from the clutch pump wheel to the clutch turbine wheel.
  • the use of such a coupling for a controllable coolant pump is known from DE 101 42 263 C1.
  • the clutch pump wheel of the Föttinger clutch is located on the drive shaft of the pump. This cooperates with a clutch turbine wheel formed on the rear side of a delivery wheel of the coolant pump.
  • the feed wheel is rotatably mounted on the drive shaft.
  • the Kupplungspumpenrad contains radially inner inlet openings for a fluid.
  • a gap is formed on the outer circumference between the Kupplungsturbinenrad and the Kupplungspumpenrad through which the fluid can flow.
  • a movable slide is provided, through which the height of the outer circumferential gap is adjustable.
  • thermocouple or an external actuator.
  • the structure of such a pump is relatively complicated, since many parts are to be mounted and the manufacture and assembly, in particular with respect to the slide and the clutch turbine wheel must be carried out in close tolerance ranges.
  • the Kupplungspumpenrad is arranged axially displaceable to Kupplungsturbinenrad, can be dispensed with a separate adjusting ring. This saves components. Also, only the position of the Kupplungsturbinenrades must fit the Kupplungspumpenrad to ensure good torque transmission. Further tolerances, as with the use of a collar omitted.
  • the non-rotatable connection between the Kupplungspumpenrad and the drive shaft is made by acting in the circumferential direction positive engagement. Thus, a displacement in the axial direction and a torque-transmitting connection between the drive shaft and Kupplungspumpenrad is produced in a simple manner.
  • a driver is arranged on the drive shaft, which is connected to the drive shaft and through which the positive connection is made to the Kupplungspumpenrad. Accordingly, can be dispensed with an additional mechanical machining of the drive shaft, so that the production is facilitated.
  • the force acting in the circumferential direction positive connection is made by two corresponding multi-tooth profiles, of which a plurality of profile on an outer circumference of the drive shaft or the driver and a splined profile on a Inner circumference of the Kupplungspumpenrades is formed.
  • a splined profile By using a splined profile, torque transfer torque is evenly distributed around the circumference increasing durability and preventing imbalance.
  • a circumferential groove is formed on the outer circumference of the Kupplungspumpenrades, in which engages a displaceable in the axial direction bolt of an actuator.
  • an advantageous embodiment of the invention results from the fact that the actuator has a rotary shaft which serves as an eccentric to which the bolt is mounted eccentrically to the rotary shaft.
  • a rotatable drive is easy to seal to the outside. The adjustment can be done via lever or directly.
  • a particularly simple structure is obtained when the rotary shaft of the eccentric is mounted in the housing of the pump, wherein between the rotary shaft and the housing, a sealing ring is arranged. So can be dispensed with additional housing or other additional components to be mounted.
  • the storage and sealing are easy to install from the outside.
  • the Kupplungspumpenrad is loaded by a spring in the direction of the Kupplungsturbinenrades. As a result, a maximum delivery of the feed wheel is ensured in case of failure of the actuator, since the distance between the Kupplungspumpenrad and the Kupplungsturbinenrad is minimized for maximum torque transmission.
  • the spring is preferably designed as a helical spring which is supported against the Kupplungspumpenrad on the axially opposite to the Kupplungssturbinenrad against the Kupplungspumpenrad.
  • a spring is easy to assemble. Also, the necessary spring force can be adjusted by the use of a correspondingly strong spring.
  • the spring abuts against its opposite to the Kupplungspumpenrad axial end against a support member which is rotatably connected to the drive shaft.
  • a relative movement between the two contact surfaces of the spring is avoided, so that a load of the spring in the circumferential direction is excluded.
  • a particularly simple assembly of the support element is achieved when the support element between a shoulder of the drive shaft and the driver is clamped to produce the rotationally fixed connection between the drive shaft and the support element. So can be dispensed with additional components for the preparation of the rotationally fixed connection.
  • the drive shaft is preferably mounted on a bearing unit, which is sealed by a mechanical seal against a pump chamber in which the Kupplungspumpenrad, the Kupplungsturbinenrad and the impeller are arranged. In this way, penetration of the pumped liquid into the bearing unit of the drive shaft is avoided. Accordingly, inexpensive grease-lubricated bearings can be used for shaft bearing.
  • a stop is formed on the outer circumference of the driver, via which the axial movement of the Kupplungspumpenrades in the direction of the Kupplungsturbinenrades is limited. Accordingly, can be dispensed with a tolerant arrangement between the actuator and Kupplungsturbinenrad. The final position of the Kupplungspumpenrades can only be determined by the stop acting directly on the Kupplungspumpenrad, which easily a precise determination of the end position and damage due to contact between Kupplungspumpenrad and Kupplungsturbinenrad be reliably avoided.
  • a controllable pump for an internal combustion engine which is simple in construction, easy to assemble and controllable with simple means.
  • the number of components is reduced.
  • a sufficient promotion of the fluid to be delivered by the impeller is ensured by an independent of the actuator starting an emergency running position of the clutch pump in case of failure of the actuator.

  • Figure 2 shows a perspective view of the pump according to the invention of Figure 1 with partially cut housing with minimal promotion.
  • FIG. 3 shows a perspective view of the clutch pump wheel.

  • the drive shaft 14 has on the side facing the pump chamber 24 side of the mechanical seal 22 a shoulder 30 against which a driver
  • the driver 32 is fixedly connected in the pressing against the paragraph position with the output shaft 14, in particular pressed, so that the support member 34 is also rotatably coupled to the drive shaft 14 by frictional connection. On its outer circumference, the driver points
  • the Kupplungspumpenrad 36 has radially extending pump blades 38, between which Pump chambers 40 are formed, which are each formed radially and axially closed on its side facing the bore 20 and have a semicircular shape.

  • a helical spring 64 is biased against the Kupplungspumpenrad 36 at the closed axial side of the Kupplungspumpenrades 36, the opposite axial end abuts against an annular radial extension 66 of the support member 34.
  • the Kupplungspumpenrad 36 is loaded in the direction of a mounted on the drive shaft 14 Kupplungsturbinenrades 68, wherein the axial movement of the Kupplungspumpenrades 36 is limited by a stop 70 mounted in a groove 70 of the driver 32 in the form of a ring against which the Kupplungspumpenrad 36th would strike before it becomes one Contact with the axially opposite Kupplungsturbinenrad 68 would come.
