Definitions

  • the invention relates to a pump device for a system housing of a vehicle.
  • the invention creates a pump device for a system housing of a vehicle with the features of claim 1.
  • the present invention provides pump devices which are easier and quicker to assemble and disassemble compared to the prior art. While in the prior art with a Conventional pump interacting suction filter must be installed adjacent to the interacting pump by means of additional work, in a pump device according to the invention the respective suction filter (already integrated into the pump device according to the invention) is automatically installed when the pump device is installed. Correspondingly, the respective suction filter is also automatically dismantled when the pump device according to the invention is dismantled. This significantly reduces the amount of work to be done when assembling and disassembling a pump device according to the invention together with its suction filter. It is also pointed out that the suction filter cooperating with a pump device according to the invention can be exchanged with a relatively small amount of work.
  • a further advantage of the present invention is that only the respective pump receiving opening is required to mount a pump device according to the invention with its interacting suction filter in a system housing of a vehicle/motor vehicle.
  • the use of the pump device according to the invention thus also reduces the amount of work involved in producing the respective system housing.
  • the pump device is additionally designed with at least one closure cover, by means of which the pump receiving opening of the system housing can be sealed in a liquid-tight manner in relation to an adjacent external environment of the system housing, and the electric motor arranged between an inside of the closure cover and the pump device, which is either in the pump housing or in a is arranged mechanically attached to the pump housing motor housing.
  • the closure cap which can also be described as a cover plate, can thus be used both for assembly/adjustment of the pump device in the pump receiving opening and for liquid-tight sealing of the pump receiving opening.
  • Another advantage of the embodiment of the pump device described here is its good noise behavior, since all moving / moving parts of the electric motor and the Pump device are within the pump housing and / or the motor housing.
  • the pump device is additionally designed with at least one electronic control system arranged on an outside of the closure cover, and at least one contact part guided through the closure cover, via which the electric motor is connected to the control electronics in such a way that the electric motor can be controlled by means of the control electronics.
  • the control electronics are thus reliably protected against the ingress of liquids into the control electronics by means of the closure cover after the pump device has been installed.
  • the suction filter is arranged in the filter housing, with the filter housing being fastened to the pump housing by means of a snap connection. It is therefore possible to replace the suction filter arranged in the filter housing by simply opening the snap connection.
  • the suction filter is arranged in a suction pipe formed in the pump housing or in the filter housing, through which the liquid pumped by means of the driven pump device can be sucked.
  • the pump device can thus have a comparatively compact design.
  • a suction projection is preferably formed on an end of the suction pipe pointing away from the pump device, with a central longitudinal axis of the suction projection running centrally through the suction projection being inclined to a central longitudinal axis of the suction pipe running centrally through the suction pipe such that the suction projection fits into a hole in the pump receiving opening of the System housing opening liquid or oil sump is at least partially submersible.
  • the liquid pumped by means of the pump device can thus be pumped into the liquid or oil sump at least partially submerged suction projection are sucked into the pump device. A leakage of liquid from the liquid or oil sump into the pump receiving opening is therefore hardly to be feared.
  • the pump device comprises a pressure connection pipe, which is designed as part of the pump housing, as part of the filter housing or as a separate component attached to the pump housing and/or to the filter housing and through which the liquid pumped by means of the driven pump device can be conveyed.
  • the pressure connection pipe can be immersed at least partially in a pressure connection bore opening into the pump receiving opening. This also contributes to preventing the pump receiving opening from being undesirably wetted/smeared by the liquid pumped by means of the pump device.
  • a liquid outlet opening of the pressure connection pipe is preferably set back in relation to the suction projection of the suction pipe.
  • this embodiment of the pump device when this embodiment of the pump device is assembled, before the pressure connection pipe is at least partially immersed in the pressure connection bore, this allows the pump device to be slightly tilted about an axis of rotation aligned perpendicularly to the central longitudinal axis of the suction pipe, as a result of which the suction projection is at least partly immersed in the liquid or oil sump is submersible.
  • the pump device can be an oil pump, a cooling oil pump and/or a lubricating oil pump.
  • the exemplary embodiments for the pump device listed here are only to be interpreted as examples.
  • the pump device can also be designed for other uses in a vehicle/motor vehicle.
  • Figures 1a to 1d show schematic representations of a first embodiment of the pump device.
  • the pump device shown schematically is designed for pumping a liquid which is conducted through at least one line of a system housing 10 of a vehicle/motor vehicle.
  • system housing 10 is an example of an electric drive axle of the vehicle/motor vehicle, the pump device being used as an oil pump/lubricating oil pump, in particular for pumping oil/lubricating oil.
  • the pump device can also be used in another type of system housing of a vehicle/vehicle.
  • the pump device described below can also be used advantageously as a cooling oil pump (ie for pumping cooling oil).

  • 1b and 1c show a cross section through the system housing 10 and an external view of the system housing 10 after the pump device has been installed and/or in the system housing 10 in such a way that reliable pumping/conveying operation is possible using the pump device in its operating position/active position.
  • the pumping device also has a (in Fig. 1b shown schematically) suction filter (oil suction filter) 16a, which is either in the pump housing 12 or is arranged in a mechanically attached to the pump housing 12 filter housing (suction filter housing) 16.
  • suction filter oil suction filter
  • the pump device 12a and the suction filter 16a are thus integrated together into an assembly that can be assembled, disassembled and replaced. This simplifies assembly, disassembly and replacement of the pump device that requires the suction filter 16a for its operation and offers advantageous service options, since work steps conventionally required for assembling/disassembling only the suction filter 16a ("as a separate component") can be omitted.
  • a further advantage of the joint integration of the pump device 12a and the suction filter 16a in the pump device is that only the pump receiving opening 14 is required for the assembly of the pump device 12a and the suction filter 16a. In this way, a conventional amount of work for forming a special "suction filter receiving opening" for the suction filter 16a (conventionally mounted as a “separate component") on the system housing 10 can also be dispensed with.
  • the suction filter 16a is arranged in the filter housing 16 .
  • the suction filter 16a can also be integrated into the pump housing 12 (together with the pump device 12a).
  • the filter housing 16 can be fastened to the pump housing 12 by means of a snap connection 18 . This makes it easier to attach the filter housing 16 to the pump housing 12 and possibly later detach the filter housing 16 from the pump housing 12.
