مجموعة المقعد الأمامي FAW: ال 3 المكونات الحاسمة لسلامة الركاب الفائقة

Welcome to this critical safety and ergonomic breakdown of the مجموعة المقعد الأمامي FAW (حَشد 696). هذا هو الكامل, 3-نوع المكون, passenger-side (أو “co-driver”) seat for the FAW Jiefang CA4251P66K24T1A3E5 6×4 جرار نصف مقطورة ديزل. هذا المكون “منطق” is entirely focused on safety, متانة, and long-haul comfort for the second driver or passenger.

Unlike the ‘Driver Seat Assembly’ (حَشد 695), which is a complex “air-ride” نظام, ال مجموعة المقعد الأمامي FAW (6900010-D04-C00) is a robust, mechanically-adjusting seat. إنه “منطق” is to provide a structural, load-bearing anchor point for the passenger that is fully integrated into the cab’s “safety cell.” This includes a reinforced steel frame, integrated seatbelt anchor points, and a high-density foam structure.

This in-depth guide is an essential resource for cab technicians, fleet safety managers, ومتخصصين في قطع الغيار. سنقوم بتفكيك الكل مجموعة المقعد الأمامي FAW فيه 3 أنواع مكونات قابلة للخدمة متميزة. سنقوم بتحليل “الهيكلية & منطق السلامة” of the main ‘Front seat assy’ نفسها, والحرجة “المضادة للاهتزاز” logic of the 12-piece (6 البراغي, 6 غسالات) fastener system that secures this safety device to the cab floor.

جوهر 1: ال “الهيكلية & Comfort” منطق (عنصر 1) (ال “أطول” الوحدة النمطية)

The ‘Front seat assy’ (6900010-D04-C00) is the primary component and the main serviceable part. It is a complete, “all-in-one” حَشد. إنه “منطق” is a blend of structural safety and ergonomic comfort.

1. ال “الهيكلية & أمان” منطق:

هذا هو “منطق” of survival. ال مجموعة المقعد الأمامي FAW is a primary safety device. The foundation is a heavy-gauge, welded steel frame. هذا “skeleton” is the load-bearing structure.

Critically, this frame includes the **integrated seatbelt anchor points**. These are not just drill-holes; they are reinforced, hardened steel plates designed to withstand the thousands of pounds of “shear” و “tensile” force generated in a collision. هذا “منطق” ensures the seatbelt remains anchored to the frame, protecting the passenger.

The frame also includes the integrated headrest, which has an “anti-whiplash” منطق, and a rigid backrest designed to prevent “submarining” (sliding under the lap belt) in a frontal impact.

2. ال “Ergonomic & ميكانيكي” منطق:

هذا هو “راحة” منطق. ال مجموعة المقعد الأمامي FAW provides two key mechanical adjustments:

• Fore/Aft (Sliders): The seat is mounted on two “seat tracks” أو “sliders.” هذا “منطق” allows the passenger to slide the entire seat forward or backward to achieve safe and comfortable legroom.
• Rake (Recline): The seat includes a “recliner mechanism,” a toothed, geared hinge at the pivot point of the backrest. هذا “منطق” allows the passenger to change the angle of the backrest for comfort or rest.

3. ال “متانة & مادة” منطق:

ال “soft” parts of the مجموعة المقعد الأمامي FAW are engineered for commercial-grade durability. ال “منطق” is to use materials that can withstand 10+ hours of use per day.

High-Density Foam: The cushioning is a “high-density” (high kg/m³) polyurethane foam. Unlike soft car-seat foam, هذا “منطق” provides firm, orthopedic support, منع “bottoming-out” و “packing-down” that leads to driver fatigue and back pain.

Heavy-Duty Upholstery: The cover is a “truck-grade” textile or vinyl. إنه “منطق” is to be highly resistant to abrasion (from sliding in/out), UV-resistant (to prevent fading and cracking), and chemical-resistant (for easy cleanup of spills).

جوهر 2: ال “المضادة للاهتزاز” المنطق السحابي (عناصر 2 & 3)

This group of 12 components is the “safety-critical” fastening system for the مجموعة المقعد الأمامي FAW. إنه “منطق” is to create a 6-point, vibration-proof mount that *cannot* fail.

The system consists of six (6) ‘Inner hexagon cylindrical head screws’ (CQ2180820F6) and six (6) ‘Spring washers’ (Q40308F6).

عنصر 2: ‘Inner hexagon… أفسد’ (CQ2180820F6): This is the bolt. ال “منطق” of choosing an “inner hexagon” (رأس ألين) is for high-torque application. It allows a technician to apply a very high, precise clamping force without the tool “slipping.” ال “cylindrical head” logic allows the bolt to sit flush or recessed within the seat rail, preventing it from snagging cargo or clothing.

عنصر 3: ‘Spring washer’ (Q40308F6): هذا هو “المضادة للاهتزاز” منطق. أ “غسالة الربيع” (أو “split washer”) is a hardened steel ring that has been split and twisted. When the bolt (عنصر 2) is tightened, this washer is flattened.

هذا “flattening” creates two “منطق” functions: 1) إنه يوفر “spring tension,” constantly pushing back against the bolt head, preventing it from loosening. 2) Its sharp, cut edges “bite” into both the bolt head and the seat rail. هذا “biting” logic makes it physically impossible for the bolt to vibrate loose from road shock.

جوهر 3: إمكانية الخدمة & Failure Logic

ال “service logic” ل مجموعة المقعد الأمامي FAW is based on replacing the main unit and its critical fasteners.

Seat Failure: The main ‘Front seat assy’ (6900010-D04-C00) is the primary serviceable part. It is not designed to be “re-foamed” أو “re-upholstered” in the field. ال “منطق” is that if the seat has a structural failure (a cracked frame, a failed recliner), or a comfort failure (collapsed foam, torn upholstery), يتم استبدال الوحدة بأكملها.

Fastener Failure (Critical Safety): The fasteners (عناصر 2 & 3) are also serviceable parts. The ‘Spring washer’ (Q40308F6) is a **single-use component**. ال “منطق” is that once it has been flattened, إنه “ربيع” tension is compromised. Re-using an old spring washer is a critical safety error that can lead to a loose seat.

ال “service logic” for replacing a مجموعة المقعد الأمامي FAW is to unbolt the 6 البراغي, remove the old seat, place the new seat, and secure it with **6 new bolts (CQ2180820F6) و 6 new spring washers (Q40308F6)** to guarantee a safe, factory-spec, anti-vibration installation.
