Conjunto lógico do guarda-lamas traseiro FAW: Um guia mestre de 16 partes para proteção total nas estradas

Welcome to this critical safety and structural analysis of the Conjunto lógico do guarda-lamas traseiro FAW (Conjunto 707). Este é o completo, 16-tipo de componente, heavy-duty “splash and spray” suppression system for the FAW Jiefang CA4251P66K24T1A3E5 6×4 trator semirreboque diesel. This is not a cosmetic accessory; it is a primary “lógica” assembly with a critical three-part function:

1. Protection Logic: To shield the chassis, ‘Air Tank’ (Conjunto 393), and ‘Brake Chamber’ (Conjunto 419) from a high-velocity “sandblast” of rocks, água, sal, and road debris.

2. Safety Logic: To suppress “road spray” (atomized water) from the drive axles, which is a legal requirement in many regions to prevent blinding other motorists.

O Conjunto lógico do guarda-lamas traseiro FAW is an engineered system of “estrutural” e “sacrificial” componentes. O “lógica” is to create a rigid, vibration-proof steel “esqueleto” (the ‘Support Frames’ and ‘Brackets’) that then holds the large, “sacrificial” polymer ‘Mudguard’ panels. This modularity is key to a low cost of ownership.

This in-depth guide is essential for fleet managers, body shop technicians, e especialistas em peças. Vamos desconstruir todo Conjunto lógico do guarda-lamas traseiro FAW em seu 16 distinct component types. Iremos analisar o “structural skeleton” lógica (quadros, suporta, bases), o “protection skin” lógica (the mudguards and deflectors), and the massive 62-piece “antivibração” sistema de fixação.

Essencial 1: O “Structural Skeleton” Lógica (Componentes 3-7) (O “Mais longo” Módulo)

A fundação do Conjunto lógico do guarda-lamas traseiro FAW é o seu “esqueleto.” This is a 7-piece, modular, heavy-duty steel framework that anchors the entire assembly to the truck’s chassis rails. Este é o “mais longo” and most critical part of the system.

1. O “Main Frame” Lógica (Componente 3):

The ‘Rear mudguard fixed support frame welded assy’ (5103505-91C) é o “backbone” of the assembly. The list calls for four (4) destes. O “welded assy” (焊接总成) logic means this is a fabricated, high-strength steel component.

Este componente “lógica” is to be the primary “anchor.” It bolts directly to the truck’s chassis frame (using fasteners 12 & 13) and acts as the main load-bearing “arm” that cantilevers *out* over the dual-drive axles. It is designed to be immensely rigid, resisting the constant “flapping” (vibração) of the mudguard.

2. O “Sub-Frame” Lógica (Componentes 4 & 5):

The ‘Left/Right rear mudguard support’ (5103391-91C / 5103392-91C) are the secondary “lógica” componentes. These are the *vertical* supports. Deles “lógica” is to bolt to the *end* of the ‘Main Frame’ (Componente 3), providing the vertical mounting “face” that the ‘Mudguard’ panels (Componentes 1 & 2) actually attach to. Esse “sub-frame” logic creates a strong, modular “T” shape.

3. O “Anchor Base” Lógica (Componentes 6 & 7):

The ‘Left/Right rear mudguard support fixed base’ (5103373-91C / 5103374-91C) são os “chassis-side” anchors. O “lógica” of these components is to be the “mating flange.” They are the heavy-duty steel plates that bolt *to the chassis rail*. The ‘Main Frame’ (Componente 3) then bolts *to this base*.

Esse “modular” logic is for serviceability. In a collision, if the main arm (Componente 3) is bent, the technician can unbolt it from this “Base” (Componente 6/7) and replace it, without having to re-align a new bracket to the chassis frame itself. This entire 7-part (4+1+1+1) “esqueleto” is the core of the Conjunto lógico do guarda-lamas traseiro FAW.

Essencial 2: O “Protection Skin” Lógica (Componentes 1, 2, 14, 15, 16)

This group of components is the “sacrificial skin” do Conjunto lógico do guarda-lamas traseiro FAW. These are the parts designed to take the impact and be replaced.

Componentes 1 & 2: ‘Left/Right rear mudguard’ (5103361-50A / 5103362-50A): These are the main “mudguard” panels. Deles “lógica” is to be a massive “shield.” They are molded from a durable, flexible, high-impact polymer. Esse “material logic” é a chave: they are flexible enough to “flap” without breaking, strong enough to deflect rocks, e 100% corrosion-proof.

Componentes 15 & 16: '…Anti-spray deflector’ (5103381-54B / 5103382-54B): Este é o “Safety Logic.” Esses “deflectors” são os “brush” ou “astroturf” style strips that hang from the mudguard’s edge. Deles “lógica” is to *suppress spray*. They “pegar” the fine, atomized mist of water and let it “drip” rather than “spray,” which is a legal requirement to prevent blinding other drivers.

Componente 14: '…Cinta superior’ (5103466-50A): Este é o “rigidity logic” for the plastic. Esse “brace” is a metal strip that bolts along the *top edge* of the plastic mudguard, preventing it from “flacidez” ou “warping” over time.

Essencial 3: O “Antivibração” Lógica do Fixador (Componentes 8-13)

Este é o “lógica” que detém o Conjunto lógico do guarda-lamas traseiro FAW together. This system is subjected to the *worst* vibration on the entire vehicle (unsprung mass vibration). A standard fastener system would fail in hours.

Componentes 8, 9, 11, 12 (‘Combination bolt’): The assembly uses a total of 40 “Combinação” (combinação) parafusos. O “lógica” of these bolts is their *captive, pre-attached lock washer* (Por exemplo, a spring or serrated washer). This lock washer “bites” into the steel, providing constant tension that is *immune to vibration*.

Componentes 10 & 13 (‘Hexagon nut’): The assembly uses a total of 30 “Nuts” to complete the “lógica.” Estes são “torque predominante” (Nyloc) contraporcas. Deles “lógica” is a nylon insert that *grips* the bolt threads.

Esse “dual-fastener” lógica (a lock washer on the bolt + a lock nut on the other end) creates a “failsafe” connection that *cannot* vibrate loose. This is why all 16 of these components are critical, “single-use” serviceable parts. Re-using a lock nut is a critical safety failure, as it will lead to the Conjunto lógico do guarda-lamas traseiro FAW detaching from the vehicle.
