Tapis et bandes de seuil FAW: Le 11 MSU essentiels pour un sans faille, Cabine silencieuse

Bienvenue dans cette analyse des composants critiques du Tapis et bandes de seuil FAW (Assemblée 692). C'est le complet, 11-component-type, “floor finishing” et “entry sealing” système pour le FAW Jiefang CA4251P66K24T1A3E5 6×4 tracteur semi-remorque diesel. Cette assemblée est la “final layer” of the cab’s interior, fournissant le “logique” for driver comfort, durabilité, and a premium, finished appearance.

Le Tapis et bandes de seuil FAW system is a multi-functional kit. It works *on top of* the ‘Soundproofing Pad’ (Assemblée 623) to provide two primary functions. D'abord, the ‘Floor Carpet’ MSUs provide the “comfort and acoustic logic,” acting as a durable wear-surface that also *absorbs* in-cab noise. Deuxième, the ‘Threshold Strip’ MSUs provide the “sealing and protection logic,” locking down the carpet edges and protecting the high-traffic “sill” of the door frame.

This in-depth guide is an essential resource for cab technicians, collision repair specialists, and parts managers. Nous déconstruirons l'ensemble Tapis et bandes de seuil FAW assemblage dans son 11 Unité minimale utilisable distincte (MSU) genres. We will analyze the 4-piece “modular carpet” logique, the critical “scuff plate” logic of the threshold strips, and the 24-piece “polymer-safe” fastener system that ensures a perfect, rattle-free fit.

Cœur 1: Le “Modular Carpet” Logique (MSU 1-4) (Le “Plus long” Module)

Ce groupe de MSU forme le “confort” et “Nvh” layer of the Tapis et bandes de seuil FAW système. It is a 4-piece, modular assembly, allowing for precision fit and serviceability.

1. Le “Logique” of Modular Design:

The cab floor is a complex, 3D shape with a large transmission tunnel. Manufacturing a single, one-piece molded carpet is inefficient and makes installation impossible without removing the dashboard and seats.

Le “logique” of this 4-piece kit is “serviceability.”

• MSU 1: ‘Left floor carpet assy’ (5109215CD04)
• MSU 2: ‘Right floor carpet assy’ (5109222-D04)
• MSU 3: ‘Middle floor carpet-with storage box’ (5109226AD04)
• MSU 4: ‘Rear floor carpet-with 2KW independent heater’ (5109231BD04)

Ce modulaire “logique” is a cost-saver. If a driver spills a large amount of oil on the passenger side, the technician only needs to replace the ‘Right floor carpet assy’ (MSU 2), not the entire, expensive, one-piece carpet. The part names also reveal their specific “logique”—MSU 3 is cut to fit the ‘Storage Box’ and MSU 4 is cut to fit the ‘2KW independent heater’, meaning this is a precision, no-trim-required kit.

2. Le “Nvh & Durabilité” Logique:

Le Tapis et bandes de seuil FAW are not standard “home” carpet. This is a high-grade, automotive-spec MSU.

Durability Logic: The carpet is made from a dense, “tufted,” et “non-loop” (cut-pile) polypropylene fiber. Ce “logique” is for durability. UN “loop-pile” carpet would “snag” on work boots and unravel. This cut-pile design is fused to a heavy-duty, étanche “mass backing.” This backing prevents abrasion and stops any spilled water from *ever* reaching the ‘Soundproofing Pad’ (623) or the metal floor, preventing mold and rust.

Acoustic Logic: This is the final “Nvh” (Noise, Vibration, Harshness) layer. The ‘Soundproofing Pad’ (623) *blocks* low-frequency noise. This carpet’s “logique” is to *absorb* high-frequency noise. Le “doux” pile acts as an “acoustic trap,” absorbing in-cab sound (radio, conversation) and high-frequency “tire hiss.” Ce “anti-echo” logic is what makes the cab quiet and comfortable.

Cœur 2: Le “Scuff Plate” Logique (MSU 5-8)

Ce groupe de MSU est le “threshold” component of the Tapis et bandes de seuil FAW. C'est le “sealing” et “protection” logic for the single highest-traffic area of the truck: the door sill.

MSU 5-8: Le “Sill Strip” MSU (Gauche & Droite, Devant & Milieu)

• ‘Left door sill front strip’ (5109511-B27)
• ‘Right door sill front strip’ (5109512-B27)
• ‘Left door sill middle strip’ (5109521-B27)
• ‘Right door sill middle strip’ (5109522-B27)

Logique de protection: Le “logique” of these four MSUs is to act as a “scuff plate.” This is the part of the cab the driver *steps on* every time they enter or exit. A simple painted metal sill would be “scuffed” to bare metal in weeks. This MSU is a durable, high-impact, textured polymer (abdos) plate that is 100% scuff-resistant and corrosion-proof.

Scellage & Finishing Logic: C'est le “anti-hochet” et “finishing” logique. This trim piece provides the *final*, clean edge that “locks down” the ‘Floor Carpet’ (MSU 1 & 2) and *covers* the ‘Door Sealing Strip’ (Assemblée 691). Ce “logique” prevents the carpet from “bunching up” and ensures the main door seal is not accidentally “kicked” or dislodged by the driver’s boot.

Cœur 3: Le “Vertical Kick” Logique (MSU 11)

The ‘Left side kick panel assy’ (5109240-D04) is the final “garniture” MSU in the Tapis et bandes de seuil FAW assemblée.

Aesthetic & Logique de protection: C'est le “vertical” piece of trim that covers the cab’s “kick panel”—the area in the driver’s footwell next to the door. C'est “logique” is purely for protection and aesthetics. It is a high-scuff, high-impact zone that is constantly kicked by the driver’s left foot.

This polymer MSU is tough, textured, and easy to clean. Its secondary “logique” is to hide the “messy” components underneath it, such as the ‘Cab Fuse Box’ (Assemblée 585), hood-release cables, and the main ‘Cab Electrical Harness’ (Assemblée 577). C'est un “service access” panel, designed to be “popped off” by a technician to access these components.

Cœur 4: Le “Polymer-Safe” Logique de fixation (MSU 9 & 10)

This final group is the “fastening logic” for the entire Tapis et bandes de seuil FAW kit. It is a 24-piece system (12 vis, 12 rondelles) designed specifically for *polymer-on-metal* mounting.

MSU 9: ‘Cross recessed pan head screw’ (Q2140616F6) – Quantité 12

MSU 10: ‘Large washer’ (Q40206F6) – Quantité 12

Le “Logique” of the Pair: Le “logique” here is that these MSUs are used as a *matched set*. The ‘Sill Strips’ (MSU 5-8) and ‘Kick Panel’ (MSU 11) are “doux” polymer.

A screw head (MSU 9) alone would create a “high-pressure point” and *crack* or *pull-through* the plastic trim.

The ‘Large washer’ (MSU 10) est le “logique” ça empêche ça. It *distributes* the clamping force of the screw head over a wide surface area, allowing the trim to be fastened securely without being damaged. This 12-point “polymer-safe” fastening logic is what ensures the Tapis et bandes de seuil FAW remain secure, fonctionnel, and rattle-free.
