Definitions
- the invention relates to an electric vehicle vacuum pump arrangement, which has a pump unit and a drive unit driving the pump unit.
- An electrically driven 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 millibars, which is required, for example, for operating a pneumatic brake booster and / or other pneumatically operated ancillaries.
- a negative pressure for example, 100 millibars
- 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.
- the vacuum pump arrangement fall corresponding amounts of heat loss both in the drive motor and in the pump unit, which must be reliably dissipated in order to reliably rule out overheating, in particular the drive motor can.
- the noise emissions can be so significant that extensive measures for soundproofing and / or soundproofing must be made.
- an electric vacuum pump assembly which has a simple cover on the outlet side of the pump unit as a soundproofing measure.
- 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 on 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 pumping unit, an axial forced ventilation bypasses the damping arrangement and through the rotor 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 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.
- the drive motor ventilation outlet and an air inlet of the pump unit are fluidically coupled directly to one another.
- the ventilation outlet of the drive motor forms more or less directly the air inlet of the Pumping unit, so the suction port 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
- 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 supported on the Schallabnungsgephaseuse damped 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 mechanical damping of the composite movements is improved, while at the same time substantially increasing the transmission of structure-borne noise from the composite to the sound-shielding housing.
- 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 5 twist-locking form-fitting between the damping body on the one hand and the composite or the Schallabtungsgephaseuse other hand.
- the Schallabnungsgephaseuse on the outside rigid mounting elements, which allows a rigid and undamped attachment o the entire vacuum pump assembly on a motor vehicle Teif.
- the vacuum pump assembly can 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.
