Логика переднего брызговика FAW в сборе: The 5 Критически важные компоненты для безупречного, Безопасная кабина

Добро пожаловать на этот углубленный технический анализ Логика переднего брызговика FAW в сборе (Сборка 708). Это полный, 5-тип компонента, “upper wheel arch” system for the FAW Jiefang CA4251P66K24T1A3E5 6×4 дизельный полуприцеп тягач. This assembly is a critical “логика” system with a dual-function: 1) to act as a “splash shield,” protecting the cab and mirrors from road debris, и 2) to act as an “aerodynamic fairing,” smoothing airflow to reduce drag and wind noise.

The “логика” принадлежащий Логика переднего брызговика FAW в сборе является а “modular” и “жертвенный” дизайн. It consists of a heavy-duty, internal “steel skeleton” (the ‘Support Brackets’) that bolts rigidly to the cab. The visible, external “skin” (the ‘Mudguard’ panels) is a lightweight, flexible polymer. Этот “логика” ensures that in a minor collision or from a tire blowout, а “жертвенный” polymer panel is destroyed, while the structural steel brackets and the cab itself are protected, dramatically reducing repair costs.

This expert guide is an essential resource for collision repair specialists and parts managers. We will deconstruct this entire assembly into its 5 distinct serviceable component types. Мы проанализируем “защита & aero logic” of the main polymer panels, а “structural logic” of the 4-piece steel sub-frame, и “anti-vibration logic” of the massive 32-piece fastener system.

Основной 1: The “Sacrificial Skin” Логика (Компоненты 1 & 2) (The “дольше” Модуль)

The primary components, and the main “жертвенный” исправные части, are the ‘Left upper mudguard’ (5103161-А01) and the ‘Right upper mudguard’ (5103162-А01). These are the large, visible panels that sit above the front steer tires, integrated with the ‘Wing Panel’ (Сборка 622) below them.

1. The “Защита & Безопасность” Логика:

Это #1 “логика” этой ассамблеи. The front steer tires rotate at high speed, picking up and “flinging” a constant barrage of road debris. This mudguard acts as the primary “splash shield.”

Логика безопасности: Its first job is to protect *other drivers*. It blocks the “rooster tail” of water spray that can blind adjacent cars. Its second job is to protect the *driver’s* vision, by shielding the ‘Side Window’ (634) and ‘Wing Mirrors’ (702/703) from mud and spray.

Логика защиты: This panel is the “armor” for the ‘Welded Cab Assembly’ (617) A-pillar and door. It stops rocks and gravel from “sandblasting” the paint, preventing rust. It also protects the ‘Side Deflector’ (643) and the door’s seals from being torn or damaged.

2. The “Материал & Aero” Логика:

These panels are not metal. They are molded from a high-impact, flexible, UV-stabilized polymer. Этот “material logic” is superior for this high-impact zone:

• Flexibility: It can be struck by a rock or tire fragment and “flex,” absorbing the impact without denting or cracking.
• Corrosion-Proof: Это 100% immune to the rust and road salt that would destroy a steel panel.
• Aerodynamic: The polymer can be molded into a complex, “curved” fairing. Этот “aero logic” smooths the turbulent air coming off the front of the tire, reducing drag and wind noise (ШВХ).

3. The “Удобство обслуживания” Логика:

This mudguard is the most likely component to be damaged in a minor collision or a tire blowout. The “modular logic” of this assembly means that this “жертвенный” polymer panel can be unbolted and replaced in minutes, saving the fleet a costly repair to the cab’s main body.

Основной 2: The “Structural Skeleton” Логика (Компоненты 3 & 4)

This group of components is the “скелет” of the assembly. This is the heavy-duty, 4-piece, fabricated steel framework that the “skin” (Компоненты 1 & 2) bolts onto.

Компонент 3: ‘Upper mudguard front support bracket assy’ (5103140-А01) – Кол-во 2

Компонент 4: ‘Upper mudguard rear support bracket assy’ (5103150-А01) – Кол-во 2

The “Логика” of the 4-Point Frame: The “логика” here is to create a rock-solid, “4-point” sub-frame (a front and rear bracket for each mudguard) that bolts directly to the ‘Welded Cab Assembly’ (617).

Эти “welded assy” (焊接总成) components are the “шасси” of the mudguard. Их “логика” is to provide the absolute rigidity needed to support the large, flexible polymer panels. They prevent the mudguards from “flapping” или “вибрирующий” at highway speeds, which would quickly lead to fatigue failure. They are the “якорь” that all road forces are transferred to.

As serviceable parts, these brackets are replaced after a collision has bent them, as a bent bracket will make it impossible to align the new mudguard panel correctly.

Основной 3: The “Анти-погремушка” Логика крепления (Компонент 5)

The final component is the ‘Combination bolt’ (CQ1460616B). The parts list calls for thirty-two (32) of these.

The “Логика” из 32 Болты: This high quantity is the “anti-flex” и “anti-rattle” логика. It means that *each* mudguard (Левый и правый) is secured to its front/rear brackets by a **16-point** fastener pattern.

This high-density “quilting” pattern is the “логика” that makes the “мягкий” flexible polymer panel (Компонент 1/2) act as one “solid,” rigid unit with the “hard” steel frame (Компонент 3/4). This is the key to preventing the “drumming” noise and vibration that would otherwise plague such a large, flat panel.

The “Комбинация” Логика: The “Комбинация” (комбинация) designation is the “антивибрационный” логика. Это не стандартные болты. Each one has a *captive, предварительно установленная стопорная шайба* (НАПРИМЕР., зубчатая или пружинная шайба). This lock washer “bites” into the bracket, providing constant tension that makes the fastener *immune* to vibration. This is a critical serviceable part that ensures the mudguard does not shake itself loose.
