Definitions

  • the invention relates to an adjustment device for headlamps with a running in a predetermined direction adjusting screw which is in threaded engagement with a light module of the headlamp for pivoting about a horizontal or vertical axis, and with a coaxially arranged at a rear end of the adjusting screw drive means ,
  • an adjustment device for headlights in which for the basic adjustment of a light module of the headlamp mounted in an adjusting direction screw is provided which has a thread for coupling to the light module of the headlamp.
  • the adjusting screw is connected at a rear end with a drive means which has a bevel gear, on the toothing, for example, an auxiliary tool is vulnerable to the rotation of the adjusting screw about its axis.
  • the light module connected to the front end of the adjusting screw can be pivoted about a horizontal or vertical axis for basic adjustment of the headlight.
  • a disadvantage of the known adjusting device is that it has a relatively high space requirement, in particular in an area outside the headlight housing.
  • Object of the present invention is therefore to develop a setting device for headlights such that with little effort allows easy installation, the space requirement of the adjustment outside the headlight housing is relatively low.
  • the invention in conjunction with the preamble of claim 1, characterized in that as driving means a rear end of the adjusting screw receiving detent sleeve and a detent surrounding drive element are provided, wherein the detent sleeve has resilient in the radial direction retaining fingers, the in an assembly position against an inner surface press the drive element, and wherein the latching sleeve and the drive element are coupled via latching means in the axial direction latching with each other.
  • the invention enables a compact design of an adjusting device, in particular in an area outside a headlight housing.
  • a locking sleeve receiving detent sleeve is coaxial and disposed within a drive element, wherein only free end portions of the detent sleeve can project axially beyond the drive element.
  • the drive element need only have such an axial length that retaining fingers of the locking sleeve can press against an inner surface of the drive element to ensure a radially secured mounting of the adjusting screw and the detent sleeve.
  • An axial securing takes place by latching means, which are preferably arranged at a free end of the latching sleeve or the drive element.
  • a manual assembly with little effort is made possible when a rear end of the screw is inserted into the latching sleeve and then pressed together with the same up to the end position within the drive element, in which an axial fixation takes place at least against an installation direction by latching.
  • the latching sleeve has a number of radially outwardly projecting driving webs, which cooperate with corresponding recess of the drive element so that after axial engagement of the driving webs in the recesses, the latching sleeve is the same rotationally fixed to the drive element.
  • a guided axial movement of the locking sleeve is made possible relative to the drive element from the starting position to the mounting position.
  • the locking sleeve has an outside
  • Ring groove in which engages in an initial position, an inwardly projecting retaining ring of the drive element and thus allows a defined releasable connection between the locking sleeve and the drive element.
  • the assembly thus formed can thus be easily provided for the assembly process. With complete insertion of the locking sleeve in the drive element, the mounting position is reached, in which the locking sleeve is not detachably connected to the drive element.
  • the adjusting screw on a limiting collar which presses a sealing ring axially against a housing wall of the light module in the mounting position, so that the sealing requirements are met.
  • FIG. 1 is a perspective view of a locking sleeve and a drive element of a setting device in a starting position before installation
  • Fig. 5 is a longitudinal section through the components of the adjusting device in the mounting position.
  • An adjustment device 1 for headlights is used for mechanical basic adjustment of a light module 2 about a horizontal and / or vertical pivot axis in the headlight.
  • the adjusting device 1 essentially has an elongated adjusting screw 3 extending in the adjusting direction, which can be brought into engagement with the light module 2 or an extension piece of the light module 2 by means of a thread 4.
  • the light module 2 has a housing with a housing wall 2 ', wherein For example, a light source and a light source associated reflector are arranged within the housing.
  • the light module 2 is pivotally mounted in the housing.
  • the thread 4 extends in a region between a front end 5 of the adjusting screw 3 and a limiting collar 6 thereof.
  • the light module 2 which is threadedly engaged with the adjusting screw 3, is inserted through a bore 8 of the housing wall 2 'so that a rear end 9 of the adjusting screw 3 is exposed outside the housing (light module housing) for mounting drive means 10, 11 of the adjusting device 1
  • the adjusting screw 3 is supported with its limiting collar 6 via the sealing ring 7 on the housing wall 2 '.
  • a locking sleeve 10 and as a second drive means, a drive element 11 is provided which are nested in accordance with Figure 3 provided for assembly. They thus form a common structural unit, which is placed in a starting position on the rear end 9 of the adjusting screw 3, axially displaced so far relative to the adjusting screw 3, until a mounting position is achieved by axial displacement of the locking sleeve 10 relative to the drive element 11, in the locking sleeve 10 and the adjusting screw 3 are secured against the direction of insertion E axially on the drive element 11.
  • the detent sleeve 10 essentially consists of an annular detent element 12, against which, contrary to the installation direction E, ie in the direction of the light module 2, a number of radially compliant retaining fingers 13 join.
  • the retaining fingers 13 extend substantially axially, wherein in the initial position, the retaining fingers 13 widen against the direction of installation E to an end-side abutment portion 14, which has a reduced opening cross-section compared to an opening defined by the retaining fingers 13 opening cross-section.
  • the annular detent element 12 has on the outside an annular groove 15 into which engages in the initial position, an internally breaking retaining ring 16 of the drive element 11.
  • the retaining ring 16 of the drive member 11 extends in an axially middle portion thereof.
  • the locking sleeve 10 For releasably connecting the locking sleeve 10 and the drive member 11, the locking sleeve 10 is inserted in the installation direction E so far into the bore of the drive member 11 until the retaining ring 16 of the drive member 11 snaps into the annular groove 15 of the annular locking element 12, so that a latching connection in the now achieved initial position of the locking sleeve 10 and the drive element 11 is given.
  • the annular detent element 12 has in the radial direction on the inside a réelleprofi- lation 17, which is in the assembled position with an arranged at the rear end 9 of the screw 3 outer profiling 18 in engagement.
  • the rear end 9 of the adjusting screw 3 is thus connected in the assembled position in the radial direction by form fit with the locking sleeve 10.
  • the locking sleeve 11 can be rotatably connected to the drive element 11, the locking sleeve 10 a number of radially projecting driving webs 19, which engage in the relative displacement of the locking sleeve 10 in corresponding recesses 20 of the drive member 11.
  • the adjusting screw 3 is inserted in the installation direction E in the limited space by the retaining fingers 13 of the locking sleeve 10, the locking sleeve 10 in mounting direction e taken along until the assembly position is reached, in which the annular detent element 12 engages behind an endseiti- ge partial annular surface 21 of the drive member 11.
  • the annular detent element 12 has circumferentially distributed barb portions 22, in which the end-side partial annular surface 21 of the drive element 11 engages.
  • the annular detent element 12 and the partial annular surface 21 of the drive element 11 in this case form detent means for axially locking the detent sleeve 10 and the adjusting screw 3 in the drive element 11. An axial displacement against the installation direction E is thereby avoided.
  • the arranged at the opposite end of the latching sleeve 10 stopper portion 14 contributes to the prevention of slipping of the locking sleeve 10 in the direction of installation E of the drive element 11 at. However, such unwanted slipping is already prevented by the bulbous shape of the locking sleeve 10 and the drive member 11.
  • the locking sleeve 10 In the assembly position, the locking sleeve 10 is connected in the radial direction by positive engagement with the drive element 11.
  • the resilient retaining fingers 13 press against an inner surface 23 of the drive member 11 in the radial direction to the outside.
  • a retaining collar 24 of the adjusting screw 3 is encompassed by radially inwardly pointing ends of the retaining fingers 13.
  • the distance between a free end 9 'of the adjusting screw 3 to the limiting collar 6 is selected such that the sealing ring 7 is compressed in the assembled position in the axial direction and thus causes a tight contact of the adjusting screw 3 on the housing 2'.
  • the drive element 11 has circumferentially on a bevel gear 25 which is engageable with a perpendicular to the adjusting screw 3 further bevel gear 26 into engagement, so that by means of an auxiliary tool, the adjusting screw 3 can be rotated about its axis A.
  • the locking sleeve 10 and the drive element 11 are preferably made of a same material, preferably a plastic composite material.
  • the partial annular surface 21 of the drive element 11 as a circumferential direction continuous annular surface be educated.
  • the locking element 12 may be formed partially annular or continuous annular.
