Conjunto lógico de lámpara combinada trasera FAW: Un desglose crítico de la 4 Componentes principales

Bienvenido a esta guía técnica crítica sobre la Conjunto lógico de lámpara combinada trasera FAW (Asamblea 568). este es el completo, multiparte, serviceable tail light and signaling unit for the FAW Jiefang CA4251P66K24T1A3E5 6×4 tractor semirremolque diésel. This assembly is the primary signaling and safety “lógica” system for the rear of the vehicle, essential for legal compliance and accident prevention.

El Conjunto lógico de lámpara combinada trasera FAW es un “lógica” system with two main purposes: “to be seen” y “to signal intent.” It is not a single light, pero un complejo, integrated housing that combines multiple light sources. Es “lógica” is to provide legally-compliant illumination for brake lights, tail lights (position lamps), Girar señales, and reverse lights in one sealed, durable, and serviceable unit.

Esta guía detallada es un recurso esencial para los técnicos profesionales., administradores de flotas, y especialistas en repuestos. Deconstruiremos todo Conjunto lógico de lámpara combinada trasera FAW en su 4 core serviceable components as listed: the ‘Left’ (3716015-91W-C00) y 'correcto’ (3716020-91W-C00) lamp housings, and the critical fastening hardware that ensures a vibration-proof and watertight installation.

Componentes principales: La izquierda’ (3716015-91W-C00) & 'Bien’ (3716020-91W-C00) Assemblies

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). These are the two complete “tail light” unidades. They are designed as mirror images of each other and are the primary signaling devices at the rear of the tractor. El “combinación” logic is the key design feature of the Conjunto lógico de lámpara combinada trasera FAW.

In older vehicles, each function (freno, señal, contrarrestar) was a separate, individual lamp. el moderno Conjunto lógico de lámpara combinada trasera 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 “lógica” circuitos, each critical for safety:

• **Brake Light (Rojo):** This is the most critical safety “lógica.” It provides an instant, high-intensity red light the moment the driver touches the brake pedal (ver montaje 541). Este “lógica” is often provided by **LEDs** because they illuminate **0.2 seconds faster** than an incandescent bulb. At 60 mph (100 kilómetros por hora), this gives the driver behind an extra 5.6 metros (18 pies) of stopping distance, which can be the difference in an accident.
• **Turn Signal / Indicator (Amber):** This is the flashing amber light, a critical safety “lógica” component for signaling intent to turn or change lanes. A bright, clearly visible signal from the Conjunto lógico de lámpara combinada trasera FAW is essential for preventing lane-change accidents with passenger cars in the truck’s blind spot.
• **Tail Light / Position Lamp (Rojo):** This is a low-intensity red light that activates with the headlights. Es “lógica” is to provide “presence,” marking the rear corners of the wide tractor at night, preventing rear-end collisions.
• **Reverse Light (Blanco):** This provides a bright, white light to illuminate the area behind the truck, un critico “lógica” 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.

El “Lógica” of Durability: Construction and Sealing

El Conjunto lógico de lámpara combinada trasera FAW is designed to survive in one of the most hostile environments on a vehicle. It is constantly subjected to vibration, water spray, sal del camino, grava, and extreme temperature swings. Es “lógica” is therefore one of extreme durability.

**1. Lens Construction:** el exterior “lens” is not glass. It is a high-impact, **polycarbonate** plastic. Este “lógica” es critico. Glass would shatter from a single rock thrown by the drive wheels. Polycarbonate is virtually shatterproof, resisting impacts. Además, the lens is **UV-stabilized** (to prevent the “yellowing” y “fogging” that plagues cheap plastic) y “hard-coated” (to resist scratching and hazing). Esto asegura la Conjunto lógico de lámpara combinada trasera FAW remains bright and clear for years.

**2. Housing and Sealing:** El “cuerpo” del Conjunto lógico de lámpara combinada trasera FAW es un robusto, vibration-dampening ABS or polymer housing. This housing is **hermetically sealed** to the lens, typically using a hot-melt butyl rubber sealant. Este “lógica” is to make the entire unit completely waterproof (often to an IP67 rating). A failed seal is a “lógica” falla. If water enters the assembly, it will short out the internal circuit boards (if LED) or corrode the bulb sockets (if incandescent), conduciendo a un “light-out” failure that will put the truck out of service.

**3. Illumination Logic (CONDUJO):** Como se mencionó, el “lógica” of modern heavy-duty lighting is **LED (Diodo emisor de luz)**. 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. Un LED es un estado sólido., “a prueba de choques” device with no moving parts or fragile filaments, haciéndolo prácticamente inmune a esta vibración. Este “encajar y olvidar” reliability is the core “lógica” del Conjunto lógico de lámpara combinada trasera FAW, saving fleets thousands in maintenance costs and downtime.

Componente central 2: El sujetador “Lógica” Sistema

El Conjunto lógico de lámpara combinada trasera 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 “lógica” to ensure a secure, a prueba de vibraciones, and serviceable mount. La lista pide 4 de cada uno, likely two for each lamp assembly.

este sistema (which uses studs from the lamp body) consists of:

• **'Empaquetadora’ (Q40110) – 4 unidades:** This is the flat washer. Es “lógica” debe colocarse primero, directly against the truck’s chassis bracket. Proporciona una amplia, superficie plana para el resto del hardware, evitando que la junta de resorte’ de “cavando en” and damaging the bracket’s paint or metal.
• **'Junta de resorte’ (Q40310) – 4 unidades:** Este es el “arandela de seguridad.” Este es el más crítico “lógica” componente del sistema de fijación. es una division, anillo angular de acero para muelles. Cuando la 'tuerca hexagonal’ esta apretado, esta lavadora está aplanada, ejerciendo una tensión constante del resorte *contra* la tuerca. This tension makes it physically impossible for the nut to vibrate loose from road shock.
• **'Tuerca hexagonal’ (CQ34010) – 4 unidades:** Este es el sujetador final que proporciona la fuerza de sujeción..

un suelto Conjunto lógico de lámpara combinada trasera FAW would quickly fail. The vibration would cause the electrical connector to “traste” (wear out), leading to intermittent lights. It would also cause the housing itself to crack from the stress. Así de sencillo, three-part “junta-resorte-tuerca” logic is an essential, engineered solution to ensure the Conjunto lógico de lámpara combinada trasera FAW remains secure for its entire service life. El 'perno combinado’ (CQ1460625) (8 unidades) is likely used to secure the *brackets* that these lamps mount to, providing the same vibration-proof “combinación” (tornillo + lavadora cautiva) lógica.
