Definitions

  • Housing device for an electronically controllable motor and method
  • the present invention relates to a housing device for an electronically controllable motor, comprising a housing with an electronic part for receiving a control unit and having a motor part for receiving a motor and with a partition which electronic part and motor part substantially separated from each other; and a conduit arrangement for transmitting electrical signals or electrical power between the electronic part and the motor part, wherein the conduit arrangement is arranged in an opening of the partition wall.
  • a housing designates an arrangement of walls
  • a housing device designates a housing with, for example, electrical lines and seals arranged therein.
  • the line arrangement is, for example, a leadframe or, for example, a leadframe.
  • the field of application of the invention extends to motorbe ⁇ exaggerated arrangements such as motor driven pumps, which are driven elec- ronisch.
  • the invention includes the technical teaching that a first portion of the conduit assembly is sealed by a seal made of thermosetting material against an inner wall of the opening and a second portion of the conduit assembly is sealed by a seal made of silicone against the inner wall of the opening.
  • the advantage of this teaching can be seen in the fact that the opening is sealed in two stages against diffusion of oil from the motor part in the electronic part.
  • the silicone acts against the thermoset material not only as a primitive redundancy, so as a second similar protection, but the two stages complement each other functionally to a largely fail-safe sealing. If the duroplas ⁇ schematic material, such as an epoxy resin, are brittle, so a seal by the preferably elastic silicone is still ensured. If, on the other hand, the silicone allows leakage, the seal ensured by the thermosetting material continues to securely seal the opening against material transfer.
  • a preferred embodiment of the invention provides that a motor is arranged in the motor part, wherein the thermoset material is adjacent to the motor.
  • the contact surface of duro ⁇ plastic material and motor is then for example in the area around the line arrangement. This ensures a particularly secure seal, since no oil can accumulate between the engine and the thermosetting material.
  • a circumferential around the opening sealing ring between the motor and the partition wall is clamped.
  • Such a sealing ring can advantageously prevent the flow of the duroplastic material in the liquid state during the production of the housing device.
  • the opening is formed substantially cylindrical, wherein the inner wall of the opening has at least one locking element in the form of a recess or elevation perpendicular to the cylinder axis.
  • Cylindrical means for example, circular cylindrical, but the base can also be, for example, oval or angular.
  • the advantage lies in the fact that plastic material and the silicone comprehensive seal is engaged by the locking element and held stable in one place. In the case of a recess in the inner wall of the duro ⁇ plastic material or the silicone flows take place during the manufacturing position into the recess, in the case of a survey it engages as it were, into the respective sealing material.
  • thermoset material and the silicone adjoin one another.
  • the engine part is flooded with oil.
  • thermoset material a secure seal against high static pressure by the typically pressure-resistant thermoset material is needed.
  • the silicone can then, for example, if micro-cracks or other forms of damage occur in the thermosetting material, leakage of oil, for example, under lower pressure than the oil in the engine part, prevent the engine part in the control part.
  • the invention also relates to a method for producing such a housing device, comprising method steps in which a housing described above is provided, wherein an electrically controllable motor with a protruding therefrom conduit assembly is received in the motor part, that the conduit arrangement through the opening in the partition wall in the Electronic part protrudes and is clamped around the opening circumferential sealing ring between the motor and partition; and then filling a liquid thermoset material into a basin formed by a motor, sealing ring and a first part of the inner wall of the opening so that a first part of the conduit arrangement is surrounded by the thermosetting material; the thermoset material is cured; and thereafter filling a silicone into a basin formed by the cured thermoset material and a second portion of the interior wall of the opening, such that a second portion of the conduit assembly is surrounded by the silicone.

  • a first lower portion of the conduit assembly 10 by a thermosetting material 13 is sealed against an inner wall 14 of the Publ ⁇ voltage 11, and a second upper portion of the conduit assembly 10 by a silicone 15 against the inner wall 14 of the Opening 11 sealed. If, for example, due to the high pressure through the oil bath, the thermosetting material 13 crumbles or breaks, so the silicone 15 further seals securely against ingress of material from the motor part 8 in the electronic part 6.

That on the inside surface 14 integrally formed locking element 17 is formed as an inwardly facing triangular nose and thus engages in the duro ⁇ plastic material 13, which is additionally spatially locked or secured.
  • thermoset material 13 and the Si ⁇ Likon 15 to adjoin each other.
  • a substantially one-piece, gap-free seal is created on the whole, which does not allow slippage or penetration of material.
  • the production is facilitated because the silicone 15 can be applied to the cured thermoset material 13.
