摘要:
The invention relates to a motor vehicle headlamp that has a housing and a light module that is connected to the housing by an adjustment device for adjusting the main beam direction thereof. The adjustment device has a threaded adjustment assembly and a pivot lever, which is supported in the housing such that it can pivot about a stationary pivot point in relation to the housing. The pivot lever has a movement input coupling section at a distance to the pivot point, with which it is coupled in a flexible manner to the adjustment assembly. The pivot lever is connected to the light module at a movement output coupling section that is at a distance to the pivot point and the movement input coupling section.

An installation actuated by pressure medium for adjusting the inclination of a headlight in relation to the road plane, especially in a motorcycle, with an adjusting cylinder mounted at the frame or the like and operatively connected with the headlight, which pivots the headlight about a cross-axis upon actuation by the pressure medium of the hydraulic brake system, to which the adjusting piston is connected.

A pneumatically operating control system for the automatic alignment of motor vehicle headlights which includes control elements coordinated to one or both axles of the motor vehicle which align the motor vehicle headlights to a constant light range as a function of the change of the distance of the respective axle with respect to the body of the motor vehicle by way of adjusting motors and a control shifting device; a preferably electrically actuated displacement valve is arranged in a connecting line between a control shifting device and an adjusting motor which, during braking and accelerating operations, eliminates the throttling effect of the connecting line, triggered by at least one switch, and leads to a rapid equalization of the change in angular value between the optical axis of the headlight and the road surface.

The device comprises a bar pivoted to a swing-bar whose ends are each connected to a piston rod of a jack having two positions. The travel of one of the jacks is equal to double the travel of the other. The front end of the bar is connected to the upper part of a headlamp and the bar is connected to the middle of the swing-bar. The ends of the latter are formed over and engaged in notches formed in a support of the device. The edges of the notches constitute abutments for the swing-bar.

What follows is the description of an improved hydraulic apparatus for the automatic adjustment of the inclination of the headlights of a motor vehicle, the adjustment being a dependent function of the axle load. The apparatus has a level sensor at each axle and each level sensor contains one metering piston and two positioning pistons. The rear axle level sensor is connected via two separate hydraulic lines to the front axle sensor, and the front axle sensor is in turn connected via two separate hydraulic lines to the positioning elements of the headlight housings. The internal construction of the two level sensors is substantially identical and is chosen such that the system is also suitable for manual adjustment.

The motor vehicle comprises a vehicle body suspended on wheels and carrying a pair of headlamps which are mounted on a common cross rod angularly movable relative to the body by means of a headlamp tilting mechanism. The headlamp tilting mechanism is of the hydromechanical type and includes a lever which is mounted on the vehicle body through the intermediary of a pivot. The lever has an arm which is urged by spring into engagement with a temperature sensitive element secured to a rear axle housing of the motor vehicle. An extension projecting from the lever is engaged by an output rod of a mechanism for rendering the tilting mechanism inoperative. The mechanism comprises a body within which is disposed a bellows element having the output rod secured thereto. Also disposed within the body is a temperature expansible material and a heating element which is arranged to be heated when a headlamp filament energizing switch is manually closed. Heating of the temperature expansible material by heating element effects movement of the output rod such that abutment thereon is moved out of engagement with the extension on the lever, thereby permitting the tilting mechanism to operate. When the headlamp energizing switch is de-energized, the temperature expansible material cools down and a spring within the bellows element moves the output rod into a position in which the abutment thereon engages the extension and moves the lever into a position in which the headlamp tilting mechanism is rendered inoperative.

The headlamp tilting system comprises a headlamp tilting mechanism and a headlamp securing mechanism. The headlamp tilting system includes a tensioned cable which leads to a sensor at the rear of the motor vehicle and is connected with a tube having a slidable output rod therein connected with a cross rod upon which headlamps of the motor vehicle are mounted. The tube is movable relative to a body of the vehicle and the output rod is connected with the tube via a pair of springs. The headlamp securing mechanism comprises a lever carrying a catch in the form of a V-shaped notch which is engageable over a pin carried by a lever secured to the cross rod. A spring biasses the lever into a position in which the catch engages the pin but an abutment on the lever engaging a pin in an elongate slot in the rod normally prevents such movement. In the event of a breakage of the cable, the springs within the tube cause a plate on the tube to engage an extension on lever to effect disengagement of the abutment from the pin. This action causes spring to urge the lever so that the catch engages the pin on the lever secured to the cross rod. In this manner, movement of the headlamps is limited.

A sealed, double valve assembly mounted on a vehicle body is connected to a source of pressurized air and controls the air pressure delivered to two auxiliary systems connected to it. The first auxiliary system is a brake force regulator and the second auxiliary system is a headlight beam adjustment mechanism which uses a pneumatic servo-member.Control rods connected to the axle change the degree of compression of a control spring in the double valve assembly, thereby opening or closing valves which admit or release compressed air so as to change the operating pressure of the associated auxiliary systems.

A pneumatically operating control installation for the automatic alignment of motor vehicle headlights, in which the control members coordinated to one or two axles of the motor vehicle which align the headlights to a constant light range as a function of changes of the distance of the respective axle to the superstructure of the motor vehicle by way of adjusting motors and a control device, are constructed as pressure modulators while a vacuum, available at all times, is fed to the control installation.
