Блок логики передней комбинированной лампы FAW: Критический анализ 3 Основные компоненты

Добро пожаловать в это важное техническое руководство по Блок логики передней комбинированной лампы FAW (Сборка 560). Это полный, multi-part, serviceable headlight and signaling unit for the FAW Jiefang CA4251P66K24T1A3E5 6×4 дизельный полуприцеп тягач. Эта сборка является “лицо” of the vehicle, defining its aesthetics and providing all critical forward-facing illumination.

The Блок логики передней комбинированной лампы FAW является а “логика” system with two main purposes: “to see” и “to be seen.” It is not a single bulb, но комплекс, 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.

Это подробное руководство является важным ресурсом для профессиональных технических специалистов., менеджеры автопарка, и специалисты по запчастям. Мы разберем всю Блок логики передней комбинированной лампы FAW в свой 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.

Основные компоненты: «Левые»’ (3711015-91W-C00) & 'Верно’ (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” единицы. They are designed as mirror images of each other and are the most prominent feature of the truck’s front end.

The “комбинация” logic is the key design feature. In older vehicles, each function (headlight, turn signal, parking light) was a separate, individual lamp. The modern Блок логики передней комбинированной лампы 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 “логика” схемы:

• **Low Beam (Dipped Beam):** This is the primary driving light, used at night. Его “логика” is to illuminate the road ahead (НАПРИМЕР., 50-75 метры) *without* blinding oncoming traffic. This is achieved by a precision reflector or projector that creates a sharp, horizontal “cut-off” линия, 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. Его “логика” is to provide maximum distance (150+ метры) 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 “логика” component for signaling intent to turn or change lanes.
• **Position Lamp (Parking Light):** A low-wattage bulb that illuminates the “corners” грузовика, 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” и “fogging” that plagued older plastic headlights. The entire unit is hermetically sealed with a butyl rubber sealant to prevent any moisture or dust from entering. А “foggy” or water-filled headlight assembly is a failed assembly.

The “Логика” of Light: Reflectors and Aiming

The “логика” inside the Блок логики передней комбинированной лампы FAW is a marvel of optical engineering. A simple bulb (like an H4 or H7 halogen bulb) blasts light in 360 степени. This is useless for driving. The assembly’s “логика” is to capture and focus this light.

This is done using a **complex-surface reflector**. The “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.

The most critical “логика” for any headlight replacement is **aiming**. A new headlight assembly is not “plug-and-play.” 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. The Блок логики передней комбинированной лампы FAW is equipped with (unlisted, but integral) adjustment screws. These screws allow a technician to precisely adjust the vertical (up/down) and horizontal (left/right) aim of the beam, ensuring it meets all legal and safety requirements.

The “Connecting Component”: «Комбинированный болт’ (CQ1460625)

The final component of the Блок логики передней комбинированной лампы FAW is the ‘Combination Bolt’ (CQ1460625). В списке запчастей указано восемь таких деталей. (four for each headlight assembly). These are the critical fasteners that secure the entire assembly to the truck’s body or radiator support structure.

The “логика” of a **”Комбинированный болт” (комбинированный болт)** 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 (non-removable) spring washer and a captive flat washer already attached to its shaft.

This design is critical for two reasons:

1. **1. Vibration Resistance:** The “Весенняя шайба” (lock washer) 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. Этот “логика” guarantees that every Блок логики передней комбинированной лампы FAW is installed with the correct anti-vibration hardware, every single time.

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