Definitions

  • the invention relates to a pressure control device, in particular motor vehicle brake pressure control device, such as an anti-lock control device, traction control device according to the preamble of patent claim 1.
  • Such a pressure control device is already known from DE 43 25 412 AI, which is provided in detail with pressure control valves arranged in a valve receiving body, which are able to electromagnetically close or open the pressure control channels within the valve receiving body.
  • a two-part cover unit is placed on the magnetic drive, which covers the parts of the pressure control valves protruding from the valve body.
  • a metallic carrier plate which receives the magnetic drives and which is clamped firmly and at the same time in a liquid-tight manner by means of a screw connection between the two housing parts.
  • Parts of a control and / or regulating electronics are also located above the carrier plate and thus within the housing part of the cover unit facing away from the valve receiving body.
  • FIG. 1 shows a simplified illustration of a partial section through a pressure control device, which essentially consists of a block-shaped, metallic valve receiving body 1, which accommodates a plurality of pressure control valves 5 arranged in parallel next to one another, which project with their magnetic drive on the surface of the valve receiving body 1 and which are in accordance with the invention with a stepped, first housing part 2 of the cover unit 3 are spatially separated from a further, second housing part 4 of the cover side 3.
  • the essentially pot-shaped Designed second housing part 4 receives a roller bearing on the pot bottom, in which the drive shaft of an electric motor 6 is guided.
  • the open section of the second housing part 4 which extends in the direction of the first housing part 2 has a radially circumferential collar which bears against the first housing part 2 via a seal 13.
  • the second housing part 4, which receives the essential parts of the electric motor 6, can be fastened to the first housing part 2 in a non-positive and positive manner.
  • rivet, screw, clip and adhesive connections for example, are suitable, which are known in detail and therefore cannot be explained in more detail.
  • the first housing part 2 attached to the valve receptacle body 1 consists of a well formable, sound-absorbing material
  • the second housing part 4 attached to the first housing part 2 away from the second valve receptacle body 1 consists of a very rigid material.
  • the second housing part 4 is therefore made of a metal, preferably thin sheet metal part
  • the first housing part 2 consists of a non-metal, preferably electrically insulating plastic.
  • the fact that the first housing part 2 is provided with a plurality of housing stages 8 at the level of the second housing part 4 results on the one hand in an optimal space utilization for the arrangement of the electric motor 6 and the pressure control valves 5 in the cover unit 3, and on the other hand also an improved rigidity of the first housing part 2, whereby the housing wall thickness of the plastic part and its ribbing are reduced to a minimum.
  • the illustration The body contour of the first housing part 2 can thus be produced simply and yet very precisely using the manufacturing processes known per se for plastic molded parts.
  • the expedient use of a housing pot made of thin sheet metal for receiving the magnets 12 of the electric motor 6 remains unaffected with all its advantages with regard to good manufacturability and the required high rigidity.
  • the shaft of the electric motor 6 is not only supported on the bottom of the pot of the second housing part 4, but also on the opposite shaft section at the same time.
  • the first housing part 2 is provided with a collar 11, which thus forms a partial mount for the shaft bearing and thus for the motor bearing 9.
  • a passage opening 7 which is adapted to the shaft diameter and which is aligned with the motor mounting 9 mounted on both sides of the shaft.
  • the proposed shaft mounting of the electric motor 6 within the first and second housing parts 2, 4 results in an independently manageable, preassembled and pre-testable structural unit, so that the electric motor 6 can be put into operation independently of the valve receiving body 1. Since the proposed electric motor is in the form of a brush rotor, there is the possibility, via the current contacts 14, which are preferably injected into the end wall of the first housing part and protrude in the direction of the valve receiving body 1, to connect a direct current source to a test device, before the valve receiving body 1 at all is mounted.
  • the two-part cover unit 3 accommodating the electric motor 6 is attached, according to FIG. 1, to the end face of the valve receiving body 1 which has the magnetic drives of the pressure control valves 5 by means of non-positive and / or positive fastening means.
  • the one shaft end projects with its eccentric into a needle bearing, which is a functional intermediate element of a pump integrated in the valve receiving body 1.
  • Another considerable advantage of the two-part cover unit 3 can be seen in the fact that the second housing part 4, as a unit part with the same connection pattern, is universal for different pressure control devices can be used.
  • the first housing part 2 takes on the function of an adapter part which, in accordance with the valve configuration of the valve receiving body 1, is relatively easy as a molded part to the emergency Agile space design for the pressure control valves 5 can be adapted.
  • the first housing part 2 can also be designed relatively easily with a constant connection diagram for receiving the second housing part 4, the first housing part 2 having a motor carrier function that is clearly recognizable.
  • control and / or regulating electronics 16 are positioned on the end face of the valve receiving body 1 for the power supply or control of the electric motor 6 and the pressure control valves 5, which results in good heat dissipation, but on the other hand also the assembly the control and / or regulating electronics 16 schematically sketched as a plate in the first housing part 2 is not excluded.
