Other common to two manual correcting devices on illumination, an automatic correction

摘要

The present invention relates to a motor vehicle headlight comprising a first lighting device (2) ensuring a lighting function of the type "dipped " and a second lighting device (41) ensuring a lighting function of the type" road ». The first device comprises a first frame (4) mounted to pivot with respect to a vertical axis (12) and a second frame (6) mounted to pivot on the first frame according to a horizontal axis (not shown in fig.). An automatic adjustment device (20) is mounted on the first frame (4) so as to be aligned with the vertical axis (12) and is connected to the second frame (6) in order to ensure adjustment of the door of the lighting beam. The second lighting device (41) comprises a frame mounted to pivot with respect to a ball joint connection (44) and a cassette of the control (52) acting on a high point of the frame (42) in order to adjust the bearing surface of the beam. The automatic adjustment device (20) comprises an outer toothing (38) acting on the mechanism for converting the rotational movement into a translational movement of the adjustment device is motorized (20). A connecting shaft (56) provides a mechanical connection between the outer toothing (38) and the cassette of the control (52). Consequently, the actuation of the cassette of the control (52) will not only act on the surface of the second device, but also on the bearing surface of the first device, and this independently of the angular position of the first frame ensuring an adjustment in a direction perpendicular to that of the bearing surface.
