Логический блок заднего комбинированного фонаря FAW: Критический анализ 4 Основные компоненты

Добро пожаловать в это важное техническое руководство по Логический блок заднего комбинированного фонаря FAW (Сборка 568). Это полный, многочастный, serviceable tail light and signaling unit for the FAW Jiefang CA4251P66K24T1A3E5 6×4 дизельный полуприцеп тягач. This assembly is the primary signaling and safety “логика” system for the rear of the vehicle, essential for legal compliance and accident prevention.

The Логический блок заднего комбинированного фонаря FAW является а “логика” system with two main purposes: “to be seen” и “to signal intent.” It is not a single light, но комплекс, integrated housing that combines multiple light sources. Его “логика” is to provide legally-compliant illumination for brake lights, tail lights (position lamps), Поверните сигналы, and reverse lights in one sealed, прочный, and serviceable unit.

Это подробное руководство является важным ресурсом для профессиональных технических специалистов., менеджеры автопарка, и специалисты по запчастям. Мы разберем всю Логический блок заднего комбинированного фонаря FAW в свой 4 core serviceable components as listed: «Левые»’ (3716015-91W-C00) и «Правильно’ (3716020-91W-C00) lamp housings, and the critical fastening hardware that ensures a vibration-proof and watertight installation.

Основные компоненты: «Левые»’ (3716015-91W-C00) & 'Верно’ (3716020-91W-C00) Сборки

The main components of this system are the ‘Left rear combination lamp assembly’ (3716015-91W-C00) and the ‘Right rear combination lamp assembly’ (3716020-91W-C00). Это два полных “tail light” единицы. They are designed as mirror images of each other and are the primary signaling devices at the rear of the tractor. The “комбинация” logic is the key design feature of the Логический блок заднего комбинированного фонаря FAW.

In older vehicles, each function (тормозный, сигнал, обеспечить регресс) was a separate, individual lamp. The modern Логический блок заднего комбинированного фонаря 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, each critical for safety:

• **Brake Light (Красный):** This is the most critical safety “логика.” It provides an instant, high-intensity red light the moment the driver touches the brake pedal (см. сборку 541). Этот “логика” is often provided by **LEDs** because they illuminate **0.2 seconds faster** than an incandescent bulb. At 60 миль в час (100 км/ч), this gives the driver behind an extra 5.6 метры (18 feet) of stopping distance, which can be the difference in an accident.
• **Turn Signal / Indicator (Янтарь):** This is the flashing amber light, a critical safety “логика” component for signaling intent to turn or change lanes. A bright, clearly visible signal from the Логический блок заднего комбинированного фонаря FAW is essential for preventing lane-change accidents with passenger cars in the truck’s blind spot.
• **Tail Light / Position Lamp (Красный):** This is a low-intensity red light that activates with the headlights. Его “логика” is to provide “presence,” marking the rear corners of the wide tractor at night, preventing rear-end collisions.
• **Reverse Light (Белый):** This provides a bright, white light to illuminate the area behind the truck, критический “логика” for safely backing up to a trailer or loading dock in the dark. It also acts as a visual signal to anyone behind the truck that the vehicle is in reverse.

The “Логика” of Durability: Construction and Sealing

The Логический блок заднего комбинированного фонаря FAW is designed to survive in one of the most hostile environments on a vehicle. It is constantly subjected to vibration, water spray, дорожная соль, гравий, and extreme temperature swings. Его “логика” is therefore one of extreme durability.

**1. Lens Construction:** Внешний “lens” is not glass. It is a high-impact, **polycarbonate** plastic. Этот “логика” имеет решающее значение. Glass would shatter from a single rock thrown by the drive wheels. Polycarbonate is virtually shatterproof, resisting impacts. Более того, the lens is **UV-stabilized** (to prevent the “yellowing” и “fogging” that plagues cheap plastic) и “hard-coated” (to resist scratching and hazing). Это обеспечивает Логический блок заднего комбинированного фонаря FAW remains bright and clear for years.

**2. Housing and Sealing:** The “тело” принадлежащий Логический блок заднего комбинированного фонаря FAW является надежным, vibration-dampening ABS or polymer housing. This housing is **hermetically sealed** to the lens, typically using a hot-melt butyl rubber sealant. Этот “логика” is to make the entire unit completely waterproof (often to an IP67 rating). A failed seal is a “логика” отказ. If water enters the assembly, it will short out the internal circuit boards (if LED) or corrode the bulb sockets (if incandescent), ведущие к “light-out” failure that will put the truck out of service.

**3. Illumination Logic (ВЕЛ):** As mentioned, а “логика” of modern heavy-duty lighting is **LED (Светоизлучающий диод)**. An incandescent bulb has a fragile, thin tungsten filament that is extremely susceptible to breaking under the constant, high-frequency vibration of a diesel truck. Светодиод — это твердотельный элемент., “противоударный” device with no moving parts or fragile filaments, делая его практически невосприимчивым к этой вибрации. Этот “«приспособил и забыл»” reliability is the core “логика” принадлежащий Логический блок заднего комбинированного фонаря FAW, saving fleets thousands in maintenance costs and downtime.

Основной компонент 2: Застежка “Логика” Система

The Логический блок заднего комбинированного фонаря FAW is mounted to the chassis (often to the rear frame crossmember or a dedicated light bracket). The parts list details a specific, three-part fastener “логика” to ensure a secure, виброустойчивый, and serviceable mount. Список требует 4 of each, likely two for each lamp assembly.

Эта система (which uses studs from the lamp body) consists of:

• **’Gasket’ (Q40110) – 4 единицы:** This is the flat washer. Его “логика” is to be placed first, directly against the truck’s chassis bracket. It provides a wide, flat surface for the other hardware, preventing the ‘Spring gasket’ от “копаться в” and damaging the bracket’s paint or metal.
• **’Spring gasket’ (Q40310) – 4 единицы:** Это “lock washer.” This is the most critical “логика” component of the fastener system. It is a split, angled ring of spring steel. When the ‘Hex nut’ is tightened, this washer is flattened, exerting constant spring tension *against* the nut. This tension makes it physically impossible for the nut to vibrate loose from road shock.
• **’Hex nut’ (CQ34010) – 4 единицы:** This is the final fastener that provides the clamping force.

Свободный Логический блок заднего комбинированного фонаря FAW would quickly fail. The vibration would cause the electrical connector to “волноваться” (wear out), leading to intermittent lights. It would also cause the housing itself to crack from the stress. Это просто, three-part “gasket-spring-nut” logic is an essential, engineered solution to ensure the Логический блок заднего комбинированного фонаря FAW remains secure for its entire service life. «Комбинированный болт»’ (CQ1460625) (8 единицы) is likely used to secure the *brackets* that these lamps mount to, providing the same vibration-proof “комбинация” (болт + невыпадающая шайба) логика.
