Problems solved by technology

[0009] One of the disadvantages of existing devices is that they have a predetermined mechanical travel, and exceeding this travel due to, for example, installation errors or negligence of the operator, can lead to the disengagement of the sleeve 9 from the mechanism 8 and, in particular, from the screw 10

Embodiment Construction

[0035] refer to image 3 with Figure 4 , which firstly show the sleeve 9 and the screw 10 for adjusting the illumination corrector 6 according to the invention. The screw has a substantially cylindrical base 101 from which extends a threaded cylindrical rod 102 which ends in a stop 11 intended to reach its A stop for the sleeve 9 is formed when adjusting the end of stroke. For this purpose, the stop 11 has a substantially cylindrical shape fitted into the outer diameter of the rod 102 . The limiting member 11 has a first radial surface 103a at one end thereof, and the first radial surface 103a is located on the side where the adjusting sleeve is located.

[0036]The stop 11 also has at its other end a substantially radial second surface 103b facing the thread of the rod 102, during the extension phase of the mechanism 8 the threaded section 92 of the sleeve 9 is positioned into the threads against the rod 102. The threaded segment 92 of the sleeve 9 encounters a stop 104...

Abstract

The invention relates to an illumination height corrector for motor vehicle headlamps with reflectors, comprising an adjustment element (9) capable of varying the inclination of said reflector (3), a screw (10) and Means (7) for actuating the translation of said screw (10), said adjustment element (9) being translatable by being screwed on or unscrewed from said screw (10) movement, for this purpose, said adjustment element (9) comprises at least one threaded segment (92), which is shaped for example to threaded engagement with said screw (10), characterized in that said screw (10) The screw thread comprises at its distal end at least one stop (104a) shaped to limit the translation of the adjustment element (9) away from the screw (10) by engaging said thread segment (92).

Description

technical field [0001] The field of the invention is that of headlights of motor vehicles, and more particularly of level correctors for these headlights. Background technique [0002] It is necessary to adjust the height of the beam emitted by the headlights so that in the main beam headlight position the headlights perfectly illuminate the road on which the vehicle is traveling and in the low beam headlight position the headlights Drivers of vehicles coming in the opposite direction will not be dazzled. For this reason, it is important to be able to adjust the elevation angle of the vehicle's headlights according to the level of the vehicle. [0003] An example of a headlamp according to the prior art is shown in figure 1 middle. Typically, a motor vehicle headlight has a housing 1 closed by a protective glass 2 . A lighting unit 5 is mounted inside the housing 1 facing the protective glass 2 in order to emit a light beam directed towards the road scene located in fron...
