مجموعة منطق المصباح الأمامي FAW: انهيار حاسم لل 3 المكونات الرئيسية

مرحبًا بك في هذا الدليل الفني المهم حول مجموعة منطق المصباح الأمامي FAW (حَشد 560). هذا هو الكامل, متعدد الأجزاء, serviceable headlight and signaling unit for the FAW Jiefang CA4251P66K24T1A3E5 6×4 جرار نصف مقطورة ديزل. هذا التجمع هو “وجه” of the vehicle, defining its aesthetics and providing all critical forward-facing illumination.

ال مجموعة منطق المصباح الأمامي FAW هو “منطق” system with two main purposes: “to see” و “to be seen.” It is not a single bulb, ولكن معقدة, integrated housing that combines multiple light sources, precision-engineered reflectors or projectors, and a durable, aerodynamic lens. Its logic is to provide optimal, legally-compliant illumination for low beams, high beams, and turn signals in one sealed unit.

يعد هذا الدليل المتعمق موردًا أساسيًا للفنيين المحترفين, مديري الأسطول, ومتخصصين في قطع الغيار. سنقوم بتفكيك الكل مجموعة منطق المصباح الأمامي FAW فيه 3 core serviceable components as listed: the ‘Left front combination lamp assembly’ (3711015-91W-C00), the ‘Right front combination lamp assembly’ (3711020-91W-C00), and the ‘Combination bolt’ (CQ1460625) fasteners that secure them.

المكونات الأساسية: "اليسار".’ (3711015-91W-C00) & 'يمين’ (3711020-91W-C00) Assemblies

The main components of this system are the ‘Left front combination lamp assembly’ (3711015-91W-C00) and the ‘Right front combination lamp assembly’ (3711020-91W-C00). These are the two complete “headlight” وحدات. They are designed as mirror images of each other and are the most prominent feature of the truck’s front end.

ال “مزيج” logic is the key design feature. In older vehicles, each function (headlight, انعطف إشارة, parking light) was a separate, individual lamp. The modern مجموعة منطق المصباح الأمامي FAW integrates all of these functions into a single, aerodynamically efficient, and sealed unit. This simplifies manufacturing, reduces drag, and provides a clean, modern aesthetic.

Each of these assemblies contains several distinct “منطق” دوائر:

• **Low Beam (Dipped Beam):** This is the primary driving light, used at night. إنه “منطق” is to illuminate the road ahead (على سبيل المثال, 50-75 متر) *without* blinding oncoming traffic. This is achieved by a precision reflector or projector that creates a sharp, أفقي “cut-off” خط, with most of the light directed down and to the right (in a right-hand-traffic country).
• **High Beam (Main Beam):** This is the maximum illumination light, used on empty roads. إنه “منطق” is to provide maximum distance (150+ متر) and spread, illuminating far down the road and to the sides. It has no “cut-off” and will instantly blind other drivers, which is why it must be “dipped” for oncoming traffic.
• **Turn Signal / Indicator:** This is the amber-colored light, a critical safety “منطق” component for signaling intent to turn or change lanes.
• **Position Lamp (Parking Light):** A low-wattage bulb that illuminates the “corners” من الشاحنة, making it visible when parked or at dusk.

These assemblies are built to be durable. The outer “lens” is not glass, but a high-impact, shatter-resistant polycarbonate. This lens is “hard-coated” to resist scratches and UV-coated to prevent the “yellowing” و “تعفير” that plagued older plastic headlights. The entire unit is hermetically sealed with a butyl rubber sealant to prevent any moisture or dust from entering. أ “foggy” or water-filled headlight assembly is a failed assembly.

ال “منطق” of Light: Reflectors and Aiming

ال “منطق” داخل مجموعة منطق المصباح الأمامي FAW is a marvel of optical engineering. A simple bulb (like an H4 or H7 halogen bulb) blasts light in 360 درجات. This is useless for driving. The assembly’s “منطق” is to capture and focus this light.

This is done using a **complex-surface reflector**. ال “chrome” bowl behind the bulb is not a simple-parabolic shape. It is a series of dozens of small, computer-designed facets, each one calculated to catch a specific ray of light and direct it to a precise spot on the road. This is what creates the sharp “cut-off” for the low beam.

الأكثر أهمية “منطق” for any headlight replacement is **aiming**. A new headlight assembly is not “التوصيل والتشغيل.” It must be aimed. If it is aimed too low, the driver will not be able to see far enough ahead. If it is aimed too high, it will blind oncoming drivers, creating a severe safety hazard. ال مجموعة منطق المصباح الأمامي FAW مجهزة (غير مدرج, but integral) adjustment screws. These screws allow a technician to precisely adjust the vertical (أعلى / أسفل) and horizontal (left/right) aim of the beam, ensuring it meets all legal and safety requirements.

ال “Connecting Component”: "الترباس المختلط."’ (CQ1460625)

المكون النهائي لل مجموعة منطق المصباح الأمامي FAW is the ‘Combination Bolt’ (CQ1460625). The parts list calls for eight of these (four for each headlight assembly). These are the critical fasteners that secure the entire assembly to the truck’s body or radiator support structure.

ال “منطق” of a **”تركيبة الترباس” (الترباس الجمع)** is a key feature for both manufacturing speed and service reliability. This is not just a standard bolt. It is a pre-assembled fastener that has a captive (غير قابلة للإزالة) spring washer and a captive flat washer already attached to its shaft.

This design is critical for two reasons:

1. **1. مقاومة الاهتزاز:** ال “غسالة الربيع” (غسالة القفل) exerts constant tension on the bolt head. In a high-vibration environment like a heavy-duty truck, a standard bolt would quickly vibrate loose, causing the headlight to rattle, lose its aim, or even fall out. This captive spring washer makes the connection vibration-proof.
2. **2. Error-Proofing:** It is impossible for the technician or assembly line worker to “forget” the washers. هذا “منطق” guarantees that every مجموعة منطق المصباح الأمامي FAW is installed with the correct anti-vibration hardware, every single time.

These eight bolts provide the rigid, ثلاث نقاط (or four-point) mounting that the headlight needs to maintain its precise aim, even after thousands of miles on rough roads.
