Abstract

So that, with few parts, a headlamp for a vehicle can be provided with a simple angle drive for positioning the reflector or additionally with the adjustment member of a lamp vertical aim system, the reflector is mounted in the headlamp housing (110) and is pivotable in a vertical and horizontal direction. A bearing bush (125) or an adjustment member of a lamp vertical aim adjustment system forms the vertical pivot bearing. A driver (123) is arranged in a driven wheel (118) of an angle drive (113) and is axially displaceable and secured against rotation and is hinged to the bearing bush (125) or to the push rod of the adjustment member by means of a snap connection. The bearing bush (125) or the adjustment member can be inserted from the outside into the housing (110) and can be fixed therein by means of a bayonet connection. <IMAGE>

Description

SPECIFICATION A headlamp for vehicles especially for motor vehicles State of the Art The invention originates from a headlamp for vehicles, especially for motor vehicles, according to the combination of features in claim 1 of the main application P 31 02 375.4. There is an increasing tendency for motor vehicles to be provided with equipment for controlling or regulating the headlamp.
Advantages of the Invention The achievement with the headlamp for motor vehicles according to the invention with few parts and in a simple manner is that the headlamp can be provided either with only a simple angle drive or additionally with the adjustment member of a lamp vertical aim system.
Advantageous further developments of the invention are described in the sub claims.
With the form of the headlamp according to claim 3 and in particular according to claim 4, the drive may be securely and simply fixed in the bush or in the push rod of the adjustment member without auxiliary means. With claim 5, the drive can be mounted in a separate element and this can be fixed to the housing.
The snap connection and the bayonet connection for the bush or the adjustment member securing the driver are particularly secure against vibration when the headlamp is also provided with the feature of claim 6.
Drawing Two embodiments of the invention are illustrated in the drawing and are explained in detail in the description of the figures. In partial section and in vertical section to normal scale; Fig. 1 shows the angle drive with a bush; and Fig. 2 shows the angle drive with an adjustment member of a lamp vertical aim controlling system.
Description of the Embodiments Of a headlamp for motor vehicles Fig. 1 shows its housing 110 of thermoplastics synthetic material provided with a round opening 111 and three end inner ramps 11 2 which are part of a bayonet connection. The housing 1 10 is fixed to the vehicle body and the reflector (likewise not shown) is mounted in it and is adjustable as regards its vertical position by an angle drive in the form of a bevel gear drive 113.
The angle drive 11 3 has a driving wheel 11 7 provided with a rod 11 6 arranged substantially vertically and an operating knob 1 20 mounted in the housing 110 and which can be actuated in one or another sense of rotation by a tool (not shown) applied substantially perpendicularly. A driven wheel 11 8 of the bevel drive 11 3 meshes with the driving wheel 117, both are similarly produced from thermoplastics synthetic material and are rotatably mounted in a bearing plate 11 9 and secured against axial movement. The driven wheel 11 8 has an opening 1 22 square in cross-section.
A driver 1 23 of thermoplastics synthetic material is square in cross-section and has a bolt 114 projecting into the interior of the housing 110 and a ball journal 125 at the opposite end. A nut 11 5 of the reflector (not shown) co-operates with the bolt 114.
A bearing bush 1 25 of thermoplastics synthetic material has a ball cup 126, a member 1 27 provided with three radially projecting locking lugs 128 and a hand grip 129. The bearing bush 1 25 can be inserted from the outside of the housing 110 into the opening 111 and be fixed by means of a bayonet joint which comes into play through the co-operation of the locking lugs 1 28 with the inner ramps 112. An 0 ring 1 30 seals the bearing bush 1 25 with respect to the housing 11 0.
In the second embodiment in Fig. 2, parts already described are provided with the same reference numerals. An adjustment member 135, likewise in the form of a bayonet connection, can be fixed in a prescribed manner in the housing 110 instead of the bearing bush 125 and a push rod 1 31 is displaceable in a cylinder 1 37 and is provided with the ball cup 1 26. A connecting pipe 1 32 issues into the operating chamber (not shown) of the cylinder 1 37. The ball journal 1 24 of the driver 1 23 is likewise fixed in the ball cup 126 by means of a snap connection.
The bevel drive 11 3 in Fig. 1 operates as follows: a rotation of the driving wheel 11 7 in one of the two arrow directions 1 33 produces consequential rotation of the driver 1 23 through the driven wheel 11 8. Due to the secured axial position of the driver 1 23 in the bearing bush 125, the rotation of the bolt 11 4 produces an axial displacement of the nut 11 5 and consequently of the reflector (not shown).
The adjustment member 1 35 in Fig. 2 superimposes on the vertical basic adjustment produced by the bevel drive 11 3 as follows: in accordance with the change in the load carried by the motor vehicle, the pressure in the cylinder 1 37 is so varied in value and direction that the push rod 131 performs a stroke in accordance with the arrow 1 34 in one or the other direction. This stroke is transmitted to the reflector through the coupled driver 123, the bolt 114 and the nut 115.
