Definitions

  • the invention relates to an electric vehicle vacuum pump assembly having a pump unit and a drive unit driving the pump unit.
  • An electrically driven motor vehicle vacuum pump generates in a motor vehicle (motor vehicle), independently of the operating state of an internal combustion engine, a negative pressure of, for example, 100 millibar, which is required, for example, for operating a pneumatic brake booster and / or other pneumatically operated ancillary units.
  • a negative pressure for example, 100 millibar
  • the electric power of the drive motor is typically in the range of 100 W for small vacuum pumps and several 100 W for large vacuum pumps.
  • corresponding amounts of heat loss occur both in the drive motor and in the pump unit, which must be reliably dissipated in order to reliably rule out overheating, in particular of the drive motor can.
  • the noise emissions can be so significant that extensive measures for soundproofing and / or soundproofing must be made.
  • the object of the invention is to provide an electric vehicle vacuum pump arrangement with a reliable cooling and low noise emissions.
  • the electric vehicle vacuum pump arrangement has a composite of a preferably rotary pump unit and a preferably coaxial drive motor for this purpose.
  • the pump unit may be, for example and preferably, a vane-cell pump unit, but may also be any other rotary and quasi-continuously conveying vacuum pump which is suitable for generating an absolute pressure of, for example, 100 millibars and less with the required volume capacity.
  • the drive motor has a rotor space in which the motor rotor rotates and has a stator space in which the motor stator is arranged.
  • a separate Schallabnungsgereheat is provided, which einhaust the composite radially and axially spaced and which has its own suction port and a separate pressure port.
  • the suction port of the sound shield case forms the suction port of the vacuum pump assembly
  • the pressure port of the sound shield case forms the outlet of the vacuum pump assembly.
  • the sound-shielding housing is formed separately from a largely, but not necessarily completely gas-tight, separate housing of the composite or of the electric drive motor.
  • the acoustic enclosure provides a significant reduction in the noise emitted by the vacuum pump assembly since the acoustic enclosure encloses and houses the aggregate of the pumping unit and drive motor on all six sides.
  • annular gas-tight structure-borne sound damping arrangement which forms a damping mechanical suspension of the composite in the Schallabnungsgephaseuse.
  • the damping arrangement is designed gas-tight and open, so that in the example annular space between the composite and the Schallabnungsgephaseuse an axial gas flow is prevented by the composite over.
  • the drive motor has an axial ventilation inlet and an axial ventilation outlet, so that when the arrangement is operated by the pump unit, axial forced ventilation takes place past the damping arrangement and through the rotor space and / or the stator space.
  • the air sucked in by the pump unit thus first flows axially through the interior of the drive motor, so that it is thereby continuously air-cooled during operation.
  • the space in which the motor coils are arranged is vented, i. in an electronically commutated drive motor, the stator space and in a mechanically commutated drive motor, the rotor space.
  • both the stator space and the rotor space can be ventilated.
  • the damping arrangement thus causes two things, namely a structure-borne noise damping suspension of the pump unit drive motor composite on the one hand and an axial forced ventilation of the drive motor on the other.
  • the drive motor vent outlet and an air inlet of the pump unit are fluidly coupled together directly.
  • the ventilation outlet of the drive motor forms more or less directly the air inlet of the pump unit, ie the suction connection of the pump unit.
  • the drive motor is therefore fluidly arranged in front of the pump unit, so that the air sucked in by the vacuum pump arrangement initially flows axially through the drive motor before it enters the pump unit flows.
  • this arrangement has the disadvantage that, because of the prevailing on the suction side of the pump unit vacuum of, for example, absolutely 100 millibar, only relatively small air masses flow axially through the drive motor, however, has the advantage that the temperature of the intake motor flowing through the intake air is relatively low. In this way, a sufficient air cooling of the drive motor can be ensured.
  • the ventilation inlet of the drive motor is axially facing away from the pump unit and the ventilation outlet of the drive motor faces the pump unit axially.
  • two gas-tight annular damping arrangements are provided which define an annular space between them axially.
  • the pump unit drive motor composite is thus stored at two axial positions radially damped on the sound shield housing or supported.
  • the two damping arrangements may, for example, be arranged axially approximately in the transverse plane of the roller bearings in order to provide a corresponding radial bearing and radial damping approximately in the transverse plane of the imbalance introduction of the imbalance generated by the two rotors.
  • the annular space between the two gas-tight damping arrangements is ventilated via a ventilation opening in the drive motor housing.
  • the ventilation opening can be very small, since it only serves to equalize the pressure between the annulus and the drive motor interior. Through the ventilation opening prevails in the annulus approximately the same air pressure as in the drive motor interior, for example, an air pressure of 100 millibar absolute. As a result, the sound transmission within the annulus significantly deteriorates, so that the noise emissions of the vacuum pump assembly are reduced accordingly.
  • the annulus may optionally be filled with a sonic absorption material, but which does not produce any appreciable mechanical or force transmitting connection between the composite and the sonic shield housing.
  • a damping arrangement is designed as a thrust bearing, which supports the pump unit drive motor composite axially.
  • a separate axial support of the composite with respect to the Schallabnungsgephaseuse is therefore not required.
  • the formation of the damping arrangement as a thrust bearing can be realized, for example, that the damping body is bordered both on its outer circumference Schallabnungsgekoruse-side and from its inner circumference composite side axially by corresponding recesses or annular lands so that a stable Axialfix réelle the composite in the Schallabnungsgepassuse is realized. Due to the negative pressure in the Schallabnungsgephaseuse at the suction-side longitudinal end of the pump unit drive motor composite is pressed with high force axially to the suction side. For the axial support is therefore a stable thrust bearing is required.
  • the damping arrangement has an annular damping body, which may consist of plastic, but particularly preferably consists of a gas-tight and open-loop elastomer.
  • Elastomers can have good mechanical damping properties, wherein the degree of damping can be adjusted for example over the axial length of the damping body.
  • the damping arrangement on a rotation which prevents twisting of the Schallabnungsgephaseuses against the composite.
  • load changes occur between the composite on the one hand and the Schallabnungsgephaseuse other rotatory Torques on which the composite would be twisted in the Schallabnungsgephaseuse, if a corresponding rotation would not prevent this.
  • the rotation can be realized, for example, by appropriate anti-rotation positive connections between the damping body on the one hand and the composite or the Schallabtungsgephaseuse other hand.
  • the Schallabnungsgekoruse on the outside rigid mounting elements, which allows a rigid and undamped attachment of the entire vacuum pump assembly to a motor vehicle part.
  • the vacuum pump assembly may for example be rigidly attached to the vehicle body or to the internal combustion engine.
  • the drive motor has a mechanical commutation arrangement, by which the motor coils, which are preferably provided on the rotor side, are driven.
  • a mechanical commutation arrangement is simple and inexpensive to produce, but generates frictional heat due to commutator friction.
  • the forced ventilation which preferably also includes forced ventilation of the commutation arrangement, the heat generated in the mechanical commutation arrangement is dissipated constantly and reliably. The forced ventilation allows in this way the use of an inexpensive mechanical commutation.
  • rotary pumping units are suitable.
  • Particularly preferred as pumping unit is a dry running vane pumping unit.
  • an automotive vacuum vehicle vacuum assembly 10 which, in a motor vehicle, provides vacuum at an absolute pressure of, for example, 100 millibars and lower.
  • the vacuum is mainly used as potential energy for actuators, such as a pneumatic brake booster or other pneumatic automotive actuators.
  • An electric drive for automotive vacuum pumps is increasingly required because the automotive internal combustion engine is not constantly running during vehicle operation.
  • the assembly 10 consists essentially of three assemblies, namely an electric drive motor 20, a coaxially arranged for this pump unit 40 and a composite 18 of the pump unit 40 and drive motor 20 enclosing all sides Schallabnungsgephase 12th

  • the drive motor 20 has on its pump-facing end face 32 a plurality of air-permeable ventilation inlets 33 through which air can flow axially into the rotor chamber 36 and the stator space 37. This air can flow out again through a drive motor ventilation outlet 47 in an end wall 44 on the pump-side end side of the drive motor 20, so that the rotor space 36 and the stator space 37 are ventilated.
  • the motor rotor 22, the motor stator 24 and the commutator 26 are continuously air-cooled during operation of the pump arrangement 10.
