Коврики и пороги FAW: The 11 Основные MSU для безупречного, Тихая кабина

Welcome to this critical component analysis of the Коврики и пороги FAW (Сборка 692). Это полный, 11-тип компонента, “floor finishing” и “entry sealing” system for the FAW Jiefang CA4251P66K24T1A3E5 6×4 дизельный полуприцеп тягач. Эта сборка является “final layer” of the cab’s interior, providing the “логика” for driver comfort, долговечность, and a premium, finished appearance.

The Коврики и пороги FAW system is a multi-functional kit. It works *on top of* the ‘Soundproofing Pad’ (Сборка 623) to provide two primary functions. Первый, the ‘Floor Carpet’ MSUs provide the “comfort and acoustic logic,” acting as a durable wear-surface that also *absorbs* in-cab noise. Второй, 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, и менеджеры по запчастям. Мы разберем всю Коврики и пороги FAW сборка в свой 11 отдельная минимальная обслуживаемая единица (МГУ) типы. We will analyze the 4-piece “modular carpet” логика, the critical “scuff plate” logic of the threshold strips, and the 24-piece “polymer-safe” fastener system that ensures a perfect, посадка без дребезжания.

Основной 1: The “Modular Carpet” Логика (МГУ 1-4) (The “дольше” Модуль)

Эта группа МГУ образует “комфорт” и “ШВХ” layer of the Коврики и пороги FAW система. It is a 4-piece, modular assembly, allowing for precision fit and serviceability.

1. The “Логика” 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.

The “логика” of this 4-piece kit is “serviceability.”

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

This modular “логика” 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’ (МГУ 2), not the entire, дорогой, one-piece carpet. The part names also reveal their specific “логика”—MSU 3 is cut to fit the ‘Storage Box’ и МГУ 4 is cut to fit the ‘2KW independent heater’, meaning this is a precision, no-trim-required kit.

2. The “ШВХ & Долговечность” Логика:

The Коврики и пороги FAW are not standard “дом” carpet. This is a high-grade, automotive-spec MSU.

Durability Logic: The carpet is made from a dense, “tufted,” и “non-loop” (cut-pile) polypropylene fiber. Этот “логика” is for durability. А “loop-pile” carpet would “snag” on work boots and unravel. This cut-pile design is fused to a heavy-duty, водонепроницаемый “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 “ШВХ” (Шум, Вибрация, Резкость) layer. The ‘Soundproofing Pad’ (623) *blocks* low-frequency noise. This carpet’s “логика” is to *absorb* high-frequency noise. The “мягкий” pile acts as an “acoustic trap,” absorbing in-cab sound (radio, conversation) and high-frequency “tire hiss.” Этот “anti-echo” logic is what makes the cab quiet and comfortable.

Основной 2: The “Scuff Plate” Логика (МГУ 5-8)

This group of MSUs is the “threshold” component of the Коврики и пороги FAW. Это “уплотнение” и “защита” logic for the single highest-traffic area of the truck: the door sill.

МГУ 5-8: The “Sill Strip” МГУ (Левый & Верно, Передний & Середина)

• ‘Left door sill front strip’ (5109511-Б27)
• ‘Right door sill front strip’ (5109512-Б27)
• ‘Left door sill middle strip’ (5109521-Б27)
• ‘Right door sill middle strip’ (5109522-Б27)

Логика защиты: The “логика” 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 (АБС) plate that is 100% scuff-resistant and corrosion-proof.

Уплотнение & Finishing Logic: Это “anti-rattle” и “отделка” логика. This trim piece provides the *final*, clean edge that “locks down” the ‘Floor Carpet’ (МГУ 1 & 2) and *covers* the ‘Door Sealing Strip’ (Сборка 691). Этот “логика” prevents the carpet from “bunching up” and ensures the main door seal is not accidentally “kicked” or dislodged by the driver’s boot.

Основной 3: The “Vertical Kick” Логика (МГУ 11)

The ‘Left side kick panel assy’ (5109240-D04) is the final “подрезать” MSU in the Коврики и пороги FAW сборка.

Эстетический & Логика защиты: Это “vertical” piece of trim that covers the cab’s “kick panel”—the area in the driver’s footwell next to the door. Его “логика” 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, и легко чистить. Its secondary “логика” is to hide the “messy” components underneath it, such as the ‘Cab Fuse Box’ (Сборка 585), hood-release cables, and the main ‘Cab Electrical Harness’ (Сборка 577). Это “service access” panel, designed to be “popped off” by a technician to access these components.

Основной 4: The “Polymer-Safe” Логика крепления (МГУ 9 & 10)

This final group is the “fastening logic” на весь Коврики и пороги FAW kit. It is a 24-piece system (12 винты, 12 washers) designed specifically for *polymer-on-metal* mounting.

МГУ 9: ‘Винт с потайной головкой и крестообразным шлицем’ (Q2140616F6) – Кол-во 12

МГУ 10: ‘Large washer’ (Q40206F6) – Кол-во 12

The “Логика” of the Pair: The “логика” here is that these MSUs are used as a *matched set*. The ‘Sill Strips’ (МГУ 5-8) and ‘Kick Panel’ (МГУ 11) являются “мягкий” polymer.

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

The ‘Large washer’ (МГУ 10) это “логика” that prevents this. 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 Коврики и пороги FAW remain secure, функциональный, and rattle-free.
