Conjunto lógico de lámpara combinada frontal FAW: Un desglose crítico de la 3 Componentes principales

Bienvenido a esta guía técnica crítica sobre la Conjunto lógico de lámpara combinada frontal FAW (Asamblea 560). este es el completo, multiparte, serviceable headlight and signaling unit for the FAW Jiefang CA4251P66K24T1A3E5 6×4 tractor semirremolque diésel. Esta asamblea es la “rostro” of the vehicle, defining its aesthetics and providing all critical forward-facing illumination.

El Conjunto lógico de lámpara combinada frontal FAW es un “lógica” system with two main purposes: “to see” y “to be seen.” It is not a single bulb, pero un complejo, 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.

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 frontal FAW en su 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.

Componentes principales: La izquierda’ (3711015-91W-C00) & 'Bien’ (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” unidades. They are designed as mirror images of each other and are the most prominent feature of the truck’s front end.

El “combinación” logic is the key design feature. In older vehicles, each function (headlight, señal de vuelta, parking light) was a separate, individual lamp. el moderno Conjunto lógico de lámpara combinada frontal 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:

• **Luz baja (Dipped Beam):** This is the primary driving light, used at night. Es “lógica” is to illuminate the road ahead (P.EJ., 50-75 metros) *without* blinding oncoming traffic. This is achieved by a precision reflector or projector that creates a sharp, horizontal “cut-off” línea, 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. Es “lógica” is to provide maximum distance (150+ metros) 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 “lógica” component for signaling intent to turn or change lanes.
• **Position Lamp (Parking Light):** A low-wattage bulb that illuminates the “corners” del camion, making it visible when parked or at dusk.

These assemblies are built to be durable. el exterior “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” y “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. A “foggy” or water-filled headlight assembly is a failed assembly.

El “Lógica” of Light: Reflectors and Aiming

El “lógica” dentro del Conjunto lógico de lámpara combinada frontal FAW is a marvel of optical engineering. A simple bulb (like an H4 or H7 halogen bulb) blasts light in 360 grados. This is useless for driving. The assembly’s “lógica” is to capture and focus this light.

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

el mas critico “lógica” for any headlight replacement is **aiming**. A new headlight assembly is not “enchufar y usar.” 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. El Conjunto lógico de lámpara combinada frontal FAW is equipped with (no estante en la lista, but integral) adjustment screws. These screws allow a technician to precisely adjust the vertical (arriba/abajo) and horizontal (left/right) aim of the beam, ensuring it meets all legal and safety requirements.

El “Connecting Component”: 'Perno combinado’ (CQ1460625)

El componente final del Conjunto lógico de lámpara combinada frontal 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.

El “lógica” of a **”Perno combinado” (perno combinado)** 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. Resistencia a las vibraciones:** El “arandela de resorte” (arandela de seguridad) 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. Este “lógica” guarantees that every Conjunto lógico de lámpara combinada frontal FAW is installed with the correct anti-vibration hardware, every single time.

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