Definitions

  • the invention relates to a mechanical motor vehicle vacuum pump which can be coupled non-rotatably via a plug-in coupling element on the pump side with a corresponding plug-in coupling element of a motor vehicle internal combustion engine and which is lubricated by lubricant supplied on the pump side.
  • the plug-in coupling arrangement consists of plug-in coupling elements which are designed to be complementary to one another and which have one or more claws which engage in corresponding recesses in the respective other plug-in coupling element.
  • the plug-in coupling arrangement is equipped with radial and axial play, so that friction occurs in the area of the plug-in coupling arrangement, which makes lubrication necessary.
  • EP 2 559 903 A1 describes a mechanical motor vehicle vacuum pump with a lubricant supply for the lubrication of a separate plug-in coupling element.
  • a blind hole in the pump rotor has a partially enlarged diameter so that the lubricant can flow in the axial direction to the separate plug-in coupling element through an annular channel surrounding a retaining bolt.
  • a mechanical motor vehicle vacuum pump which has a lubricant supply in which the liquid lubricant is transferred through a stationary lubricant supply channel in the pump housing into a rotating lubricant transport channel in the pump rotor through which the lubricant is fed a hollow cylindrical centrally arranged retaining bolt through which the lubricant is guided axially into the center of the plug-in coupling arrangement between the two plug-in coupling elements.
  • This construction is relatively complex and the retaining bolt exposed to high mechanical loads is mechanically weakened by the axial bore.
  • the lubricant must be pumped into the axial center of the rotating pump rotor, so that considerable centrifugal forces that act on the lubricant must be overcome, particularly at high speeds.
  • the object of the invention is to create a mechanical motor vehicle vacuum pump with a simply constructed lubricant supply.
  • the mechanical motor vehicle vacuum pump has a pump rotor rotatably mounted in a stationary pump housing and a separate plug-in coupling element on the rotor side.
  • the plug-in coupling element on the pump side is non-rotatably connected to the pump rotor with axial and radial play.
  • a stationary lubricant supply channel is arranged in the pump housing, through which the lubricant is pumped from a lubricant inlet on the pump housing in the direction of the plug-in coupling element to a transfer opening in the pump housing.
  • a lubricant transport channel is provided in the pump rotor, the lubricant being guided from a transfer opening through the transport channel to a lubricant outlet opening.
  • the transfer opening on the housing side and the transfer opening on the rotor side are spatially arranged relative to one another in such a way that the two openings are temporarily fluidly connected to one another at least once during a full rotor revolution of the pump rotor. This creates an intermittent flow of lubricant or an intermittent one Lubricant transfer realized.
  • the transfer opening can also be designed as a circular ring channel on the pump rotor, so that there is a constant fluidic connection between the supply channel and the transport channel.
  • the lubricant outlet opening is arranged eccentrically in an end wall of the pump rotor, specifically in the end wall which faces the plug-in coupling element on the pump side.
  • An eccentrically arranged outlet opening is to be understood as an outlet opening which is not arranged in the axial center of the pump rotor, so that the lubricant transport to the distal side of the pump-side plug-in coupling element does not essentially take place in the axial center.
  • the lubricant exiting through the outlet opening is conveyed to the outside by centrifugal forces, so that the lubricant flows through an annular gap between the plug-in coupling element and the pump rotor to the distal side of the plug-in coupling element on the pump side. In this way, lubrication of the entire coupling arrangement including the plug-in coupling element on the motor side is implemented in a structurally simple manner.
  • the plug-in coupling element on the pump side is held on the pump rotor by a central retaining bolt, the retaining bolt being fixed in a blind hole in the pump rotor.
  • the blind hole has no direct fluidic connection to the transport channel, so there is no flow of lubricant through it.
  • the eccentricity of the outlet opening is preferably greater than half the radius of the plug-in coupling end wall or the plug-in coupling element. The farther radially outward the outlet opening is, the lower are the pressure losses that result, in particular at high speeds, due to the centrifugal force that occurs radially inward counteracts flowing lubricant radially outward. This ensures a sufficient supply of lubricant to the entire clutch assembly, especially at high speeds.
  • the pump rotor end wall, in which the lubricant outlet opening is arranged, and the opposite plug-in coupling end wall are preferably located in a common transverse plane. Both end walls do not have any channels or grooves with a radially inwardly directed component.
  • the transfer opening on the housing side and the transfer opening on the rotor side lie in a common cylinder surface.
  • the retaining bolt preferably does not have any open or closed channels having an axial component.
  • the retaining bolt serves exclusively to hold the pump-side plug-in coupling element mechanically on the pump rotor, the plug-in coupling element being movable with a certain amount of play in relation to the pump rotor both in the radial and in the axial direction.
  • a vacuum pump arrangement is shown schematically, which consists essentially of a mechanical motor vehicle vacuum pump 10, an internal combustion engine 52 and one of the Internal combustion engine 52 associated lubricant pump 54 consists.
  • the vacuum pump 10 is mechanically rotationally coupled to a crankshaft or a drive shaft of the internal combustion engine 52 via a plug-in coupling arrangement 68.
  • the vacuum pump 10 is used, for example, to provide actuator vacuum for various auxiliary units of the motor vehicle, for example for a pneumatic brake booster.
  • the lubricant pump 54 conveys the liquid lubricant for the lubricant supply to the internal combustion engine 52 and the lubricant supply to the vacuum pump 10.
  • the vacuum pump 10 is a so-called vane pump and has a pump housing 14 which is essentially formed by a solid housing body 13 and a housing cover 19.
  • a pump rotor 16 that is rotatably mounted about a longitudinal axis is arranged in the pump housing 14.
  • the pump rotor sliding bearing is formed by a hollow cylinder surface 71 on the housing side and a corresponding outer cylinder surface 72 on the rotor side.
  • the pump rotor 16 has a rotor body 17 with a radial vane slot 21 in which a rotor vane 18 is mounted so as to be radially displaceable.
  • the rotor blade 18 rotates in a pump chamber 12 defined by the pump housing 14 and in this way conveys air from a pump inlet (not shown) to a pump outlet (not shown).
  • the plug-in coupling arrangement 68 is formed by two plug-in coupling elements 20, 50 which interlock in a rotationally fixed manner, but allow an axial and radial movement of the two plug-in coupling elements 20, 50 with respect to one another.
  • the pump-side plug-in coupling element 20 is in turn held in a rotationally fixed manner by the pump rotor 16 via a complex form-fitting structure 60.
  • the form-fit structure 60 also allows axial and radial mobility of the pump-side plug-in coupling element 20 in relation to the pump rotor 16.
  • the plug-in coupling element 20 on the pump side has a continuous central bore 74 through which a retaining bolt 70 is inserted, which is firmly fixed with a press fit in a central blind hole 42 of the pump rotor 16.
  • the central bore 74 has an inner diameter which is slightly larger than the outer diameter of the retaining bolt 70, so that a certain radial mobility of the plug-in coupling element 20 with respect to the pump rotor 16 is permitted.
  • the length of the socket pin shaft section, which protrudes axially from the blind hole 42, is slightly greater than the length of the axial central bore 74, so that a certain axial mobility of the plug-in coupling element 20 with respect to the pump rotor 16 is guaranteed.
  • the pump rotor 16 has a hollow cross-like interlocking structure 60, which in the Figure 1 is only shown schematically and the Figures 3 and 4th can be found in more detail.
  • the form-fit structure 60 has a bottom wall 34 lying in a transverse plane and is surrounded by a side wall 40 which defines the hollow cross-like form-fit structure 60.
  • the plug-in coupling element 20 On its side facing the pump rotor 16, the plug-in coupling element 20 has a cross-like form-fitting structure that is approximately complementary to the hollow cross-like form-fit structure, which creates a rotationally fixed coupling of the plug-in coupling element 20 to the pump rotor 16.
  • the plug-in coupling element 20 has an end wall 36, which likewise lies in a transverse plane and adjoins the bottom wall 34 on the pump rotor side in parallel.
  • a radial gap is provided between the form-fit structure side wall 40 and the peripheral wall 38 of the plug-in coupling element 20, through which a certain radial mobility of the plug-in coupling element 20 in relation to the pump rotor 16 is permitted.
  • the plug-in coupling element 20 has a plurality of axial claws 44 on its distal side, which mesh with corresponding claws of the plug-in coupling element 50 on the motor side.
  • the pump housing 14 or the housing body 13 has a lubricant supply channel 22 through which the liquid lubricant coming under pressure from the lubricant pump 54 via a line 56 from the lubricant pump 54 is passed from a lubricant inlet 24 on the housing side to a transfer opening 26 which is in the hollow cylinder surface 71 of the rotor sliding bearing is located.
  • the pump rotor 16 has a lubricant transport channel 30 through which the lubricant is guided from a transfer opening 28 to a lubricant outlet opening 32.
  • the transfer opening 28 lies in the plain bearing outer cylinder surface 72 and is arranged such that the transfer opening 28 is aligned with the transfer opening 26 once during each full revolution of the pump rotor 16, so that an intermittent flow of lubricant is realized in this way.
  • the lubricant outlet opening 32 lies in the bottom wall 34 of the form-fitting structure 60, the end wall 36 of the plug-in coupling element 20 covering the outlet opening 32, but being kept at a small axial distance by the fluid pressure of the exiting lubricant.
  • the outlet opening 32 is arranged eccentrically to the axis of rotation of the pump rotor 16.
  • the eccentricity E of the lubricant outlet opening 32 is more than 3/4 of the radius R of the plug-in coupling end wall 36.
  • the transport channel 30 is formed at right angles in the housing body 13.
  • the transport channel 30 ' which opens into the lubricant outlet opening 32', is oblique and straight. In this embodiment, the production of the transport channel 30 is simplified, since only a single drilling process is required for its production.
