Definitions

  • the invention relates to an automotive electrical motor coolant coolant pump (motor vehicle coolant pump) comprising a pump housing having at least one flow housing part and a separately formed motor housing part, the flow housing part having a spiral flow channel having an axial inlet and a tangential outlet, and a rotatably mounted fluid conveying element at least partially surrounds, and the motor housing part at least partially surrounds an electric drive motor for driving the fluid conveying element, wherein the pump housing via a mounting structure to a vehicle structure is fixable.
  • a pump housing having at least one flow housing part and a separately formed motor housing part
  • the flow housing part having a spiral flow channel having an axial inlet and a tangential outlet, and a rotatably mounted fluid conveying element at least partially surrounds
  • the motor housing part at least partially surrounds an electric drive motor for driving the fluid conveying element, wherein the pump housing via a mounting structure to a vehicle structure is fixable.
  • Such electric motor vehicle coolant pumps are well known from the prior art and are mainly used to promote a coolant for cooling a vehicle internal combustion engine. Due to the usual structure, such pumps usually have a plurality of individual housing parts, such as the flow housing part and the motor housing part, which are usually rotationally aligned with each other, are fixed to each other via a fixing device and form the entire pump housing in the assembled state. The fluidic connection of such a pump to a vehicle is usually via separately formed hoses.
  • a vehicle structure such as on a vehicle body or on an engine block
  • damping means are usually provided on the fastening structures.
  • coolant pumps must be designed individually depending on the vehicle model, in particular with regard to the required pump power, the predetermined fluidic connections, the fastening structures and the damping means.
  • the complexity of tuning the interfaces between the pump and the vehicle increases in the manufacture and assembly of the coolant pump leads to an increased cost.
  • the invention is therefore an object of the invention to provide an electric vehicle coolant pump, a cross-vehicle model
  • the attachment structure is arranged on the pump side exclusively on the flow housing part.
  • the interfaces for the fluidic and mechanical connection of the coolant pump to a vehicle structure can be limited solely to the flow housing part, so that the design of the coolant pump can be simplified.
  • the design and specification of the interfaces between pump and vehicle can be limited solely to the design of the flow housing part.
  • the motor housing part - depending vehicle model and the associated requirements For example, with regard to a model variant and / or pump performance - may have different designs or sizes and are made completely independent of the interfaces and connection requirements of the pump to the vehicle.
  • the production and installation of the coolant pump can be considerably simplified and consequently relatively inexpensive
  • the attachment structure can be a separate component, such as a clamp or a support arm, wherein the attachment structure can be adapted individually to the shape of the flow housing part.
  • the attachment structure is formed integrally with the flow housing part.
  • the attachment structure is arranged in the longitudinal extent parallel to the axis of rotation. This allows a particularly stable and relatively secure fixation of the coolant pump to the vehicle structure. In addition, the pump is thereby constructed relatively space-saving.
  • the fastening device preferably has a support arm which protrudes outward from the flow housing part.
  • the support arm has - especially at a distal end - advantageously on an opening or bore through which structure for fastening the support arm to the vehicle, a screw, a rivet, a bolt or other fastener may extend.
  • the support arm may have an outwardly projecting centering pin for aligning the support arm relative to the vehicle structure.
  • the support arm may be formed as a flange and have at least one stiffening rib.
  • the reinforcing rib can be formed in the longitudinal extent of the flange on this, thus, the support arm has a particularly high stability.
  • the attachment structure preferably has at least three attachment points for point attachment of the pump housing to the vehicle structure.
  • An attachment point may, for example, be understood to be an opening through which a screw extends for attachment. Particularly preferred exactly three such attachment points are provided.
  • the attachment points are arranged in a plane parallel to the axis of rotation.
  • a common contact plane is created, with which the fastening structure can rest and be fixed in a relatively simple manner on a contact surface of the vehicle structure.
  • the attachment points are arranged in the plane in a right triangle to each other. This allows a particularly stable fixation of the pump to the vehicle structure, in particular the pump is fixed against tilting and / or twisting.
  • the attachment structure is fixed via a frictional and / or formschiüssige connection to the vehicle structure.
  • the fastening structure on the vehicle structure can be fixed in particular detachably, particularly preferably by means of a screw.
  • the attachment structure has at least one vibration damper, preferably at an attachment point.
  • the vibration damper may in particular be suitable for damping unwanted vibrations of the coolant pump and thus preventing a loosening of the attachment of the pump to the vehicle structure as well as a noise development.
  • the vibration damper is preferably formed as an elastomeric ring which abuts in an opening, such as an attachment point, on the mounting structure.
  • the elastomeric ring for example a rubber ring, can be inserted or inserted into a hole or recess provided for this purpose in the fastening structure. This allows a relatively safe damping of the coolant pump and simplifies the installation of the coolant pump.
  • the flow housing part preferably has a centering structure for aligning the motor housing part with respect to the flow housing part.
  • the Zentrler minimalist may be a paragraph or a recess into which, for example, a pin is used.
  • a shoulder is formed on the flow housing part, on which the motor housing part can be used exclusively in a specific rotational orientation.
  • a pump rotor carrying the fluid conveying element can be used for storage in a shoulder of the flow housing part and can be rotatably mounted thereon.
  • the coolant pump can be constructed relatively compact.
  • the flow housing part preferably has an axial and / or radial gap sealing surface to the Fluid useiement.
  • Figure 1 shows schematically a side view of a mounted electric coolant pump
  • FIG. 2 schematically shows a perspective view of a flow housing part with a fastening structure.
  • an electric motor vehicle coolant pump 1 is shown in the assembled state 100.
  • the coolant pump 1 is mechanically fixed with a mounting structure 5 on a vehicle structure 6 shown only schematically.
  • the coolant pump 1 has a pump housing 2, which in the present case comprises a flow housing part 3 and a separately formed motor housing part 4.
  • a spiral flow channel 30 and a rotatable Ruid benefitelement 33 therein is arranged, which is shown in Figure 1 by a Ausbruchdarsteliung.
  • the flow channel 30 has an axial inlet 31 and a tangential outlet 32.
  • the fluid conveying element 33 is mounted on a drive shaft 11, which extends into the motor housing part 4.
  • a drive motor 40 is arranged for driving the conveying element 33 via the shaft 11, which is also shown in Figure 1 in the form of an outbreak.
  • the flow housing part 3 and the motor housing part 4 are aligned with each other and fixed to each other via a plurality of screw 21.
  • the screw 21 is designed so stable that the motor housing part 4 and the therein arranged components can be supported by the flow housing part 3 without further support.
  • a mechanical fixation of the coolant pump 1 to the vehicle structure 6 takes place exclusively via the attachment structure 5, which in the present case - as can be seen in particular in FIG. 2 - consists of two support arms 50.
  • the support arm is presently designed in each case as a flange with a stiffening rib 51.
  • the support arm 50 is formed in one piece with the flow housing part 3 and protrudes outward from the flow housing part 3.
  • the support arm 50 has a plurality of bores 52 at a respective distal end, through which in each case a screw 53 for fastening the flow housing part 3 to the vehicle structure 6 extends.
  • the flow housing part 3 is shown in a non-assembled state.
  • the fastening structure 5 consists of two support arms 50 arranged on the flow housing part 3 and protruding therefrom.
