سجاد FAW وشرائط العتبة: ال 11 وحدات MSU الأساسية لا تشوبه شائبة, الكابينة الصامتة

Welcome to this critical component analysis of the سجاد FAW وشرائط العتبة (حَشد 692). هذا هو الكامل, 11-نوع المكون, “floor finishing” و “entry sealing” نظام FAW Jiefang CA4251P66K24T1A3E5 6×4 جرار نصف مقطورة ديزل. This assembly is the “final layer” of the cab’s interior, providing the “منطق” for driver comfort, متانة, and a premium, finished appearance.

ال سجاد FAW وشرائط العتبة system is a multi-functional kit. It works *on top of* the ‘Soundproofing Pad’ (حَشد 623) to provide two primary functions. أولاً, the ‘Floor Carpet’ MSUs provide the “comfort and acoustic logic,” acting as a durable wear-surface that also *absorbs* in-cab noise. ثانية, 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, متخصصون في إصلاح الاصطدام, ومديري قطع الغيار. سنقوم بتفكيك الكل سجاد FAW وشرائط العتبة التجمع فيه 11 الحد الأدنى المتميز للوحدة القابلة للخدمة (جامعة ولاية ميشيغان) أنواع. We will analyze the 4-piece “modular carpet” منطق, the critical “لوحة أبلى” logic of the threshold strips, and the 24-piece “polymer-safe” fastener system that ensures a perfect, rattle-free fit.

جوهر 1: ال “Modular Carpet” منطق (وحدات التخزين المتنقلة 1-4) (ال “أطول” الوحدة النمطية)

This group of MSUs forms the “راحة” و “NVH” layer of the سجاد FAW وشرائط العتبة نظام. It is a 4-piece, modular assembly, allowing for precision fit and serviceability.

1. ال “منطق” 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.

ال “منطق” of this 4-piece kit is “serviceability.”

• جامعة ولاية ميشيغان 1: ‘Left floor carpet assy’ (5109215CD04)
• جامعة ولاية ميشيغان 2: ‘Right floor carpet assy’ (5109222-D04)
• جامعة ولاية ميشيغان 3: ‘Middle floor carpet-with storage box’ (5109226AD04)
• جامعة ولاية ميشيغان 4: ‘Rear floor carpet-with 2KW independent heater’ (5109231دينار بحريني04)

هذه وحدات “منطق” 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’ (جامعة ولاية ميشيغان 2), not the entire, غالي, one-piece carpet. The part names also reveal their specific “منطق”—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. ال “NVH & متانة” منطق:

ال سجاد FAW وشرائط العتبة are not standard “بيت” carpet. This is a high-grade, automotive-spec MSU.

Durability Logic: The carpet is made from a dense, “tufted,” و “non-loop” (cut-pile) polypropylene fiber. هذا “منطق” is for durability. أ “loop-pile” carpet would “snag” on work boots and unravel. This cut-pile design is fused to a heavy-duty, ضد للماء “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” (ضوضاء, اهتزاز, Harshness) layer. The ‘Soundproofing Pad’ (623) *blocks* low-frequency noise. This carpet’s “منطق” is to *absorb* high-frequency noise. ال “soft” pile acts as an “acoustic trap,” absorbing in-cab sound (راديو, conversation) and high-frequency “tire hiss.” هذا “anti-echo” logic is what makes the cab quiet and comfortable.

جوهر 2: ال “Scuff Plate” منطق (وحدات التخزين المتنقلة 5-8)

هذه المجموعة من وحدات MSU هي “threshold” مكون من سجاد FAW وشرائط العتبة. هذا هو “sealing” و “حماية” logic for the single highest-traffic area of the truck: the door sill.

جامعة ولاية ميشيغان 5-8: ال “Sill Strip” وحدات التخزين المتنقلة (غادر & يمين, أمام & وسط)

• ‘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)

Protection Logic: ال “منطق” 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 (عضلات المعدة) plate that is 100% scuff-resistant and corrosion-proof.

ختم & Finishing Logic: هذا هو “مكافحة حشرجة الموت” و “التشطيب” منطق. This trim piece provides the *final*, clean edge that “locks down” the ‘Floor Carpet’ (وحدات التخزين المتنقلة 1 & 2) and *covers* the ‘Door Sealing Strip’ (حَشد 691). هذا “منطق” prevents the carpet from “bunching up” and ensures the main door seal is not accidentally “kicked” or dislodged by the driver’s boot.

جوهر 3: ال “Vertical Kick” منطق (جامعة ولاية ميشيغان 11)

The ‘Left side kick panel assy’ (5109240-D04) هو النهائي “trim” MSU in the سجاد FAW وشرائط العتبة حَشد.

Aesthetic & Protection Logic: هذا هو “vertical” piece of trim that covers the cab’s “kick panel”—the area in the driver’s footwell next to the door. إنه “منطق” 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 “منطق” is to hide the “messy” components underneath it, such as the ‘Cab Fuse Box’ (حَشد 585), hood-release cables, and the main ‘Cab Electrical Harness’ (حَشد 577). إنه أ “service access” panel, designed to be “popped off” by a technician to access these components.

جوهر 4: ال “Polymer-Safe” المنطق السحابي (وحدات التخزين المتنقلة 9 & 10)

هذه المجموعة الأخيرة هي “fastening logic” for the entire سجاد FAW وشرائط العتبة kit. It is a 24-piece system (12 screws, 12 غسالات) designed specifically for *polymer-on-metal* mounting.

جامعة ولاية ميشيغان 9: 'برغي رأس المقلاة المجوف’ (Q2140616F6) – الكمية 12

جامعة ولاية ميشيغان 10: ‘Large washer’ (Q40206F6) – الكمية 12

ال “منطق” of the Pair: ال “منطق” here is that these MSUs are used as a *matched set*. The ‘Sill Strips’ (وحدات التخزين المتنقلة 5-8) and ‘Kick Panel’ (جامعة ولاية ميشيغان 11) are “soft” polymer.

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

The ‘Large washer’ (جامعة ولاية ميشيغان 10) هو “منطق” 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 سجاد FAW وشرائط العتبة remain secure, وظيفية, and rattle-free.
