المصد الأمامي فاو: تفكيك 9 المكونات والتجمعات الهامة

مرحبًا بكم في هذا التفكيك النقدي لل المصد الأمامي فاو حَشد. هذا هو الكامل, متعدد الأجزاء “fascia” and structural protection system for the FAW Jiefang CA4251P66K24T1A3E5 6×4 جرار نصف مقطورة ديزل. هذا التجمع هو “وجه” of the vehicle, defining its aesthetics and providing its first line of defense.

ال المصد الأمامي فاو is not a single piece, but a modular assembly. Its function is threefold: it provides the primary aerodynamic profile for the front of the truck, it houses critical components like fog lights, و, الأهم من ذلك, it is engineered to absorb and distribute impact energy, protecting the truck’s chassis and critical cooling components (like the radiator and intercooler) from damage.

يعد هذا الدليل المتعمق موردًا أساسيًا لفنيي ورش الهياكل المحترفين, مديري الأسطول, ومتخصصين في قطع الغيار. سنقوم بتفكيك الكل المصد الأمامي فاو النظام فيه 9 مكونات صالحة للخدمة, including the main ‘Left’ و"صحيح".’ bumper sections, the heavy-duty steel mounting brackets, وجميع السحابات المرتبطة بها.

المكونات الأساسية: The Bumper Assemblies (غادر & يمين)

ال “جلد” التابع المصد الأمامي فاو is a two-piece assembly, designed for cost-effective repair. This is a critical design “منطق” for any fleet vehicle.

• **’Bumper left part assembly’ (2803035-91دبليو):** This is the main left-hand (جانب السائق) قسم من المصد الأمامي فاو.
• **’Bumper right part assembly’ (2803040-91دبليو):** This is the main right-hand (passenger side) قسم.

هذه وحدات, two-piece design is a significant advantage. In a minor “corner” الاصطدام, which is common in tight urban or loading-dock environments, only the damaged section (على سبيل المثال, the ‘Bumper right part assembly’) needs to be replaced, rather than the entire, full-width المصد الأمامي فاو. This drastically reduces repair costs and vehicle downtime.

These assemblies are typically made from a combination of materials. The outer “جلد” is often a durable, paintable polymer (بلاستيك) for aerodynamics and aesthetics, while the inner, unseen structure is a heavy-gauge, stamped-steel reinforcement bar. هذا “reinforcement” is the true protective element of the المصد الأمامي فاو, designed to crumple in a specific, controlled way to absorb impact energy.

ال “Bones”: غادر (2803281-91دبليو) & يمين (2803282-91دبليو) بين قوسين

If the bumper assemblies are the “جلد,” the ‘Front bumper left bracket’ (2803281-91دبليو) and ‘Front bumper right bracket’ (2803282-91دبليو) هي “bones.” هذه هي الحرجة, مكونات هيكلية عالية القوة المصد الأمامي فاو.

These brackets are forged or fabricated from heavy-duty steel. وظيفتهم هي ربط كامل المصد الأمامي فاو assembly to the main chassis frame rails of the truck. هم “منطق” that transfers impact forces *away* from critical components and *into* the vehicle’s frame, والذي تم تصميمه للتعامل معهم.

These brackets must be incredibly rigid to prevent the المصد الأمامي فاو من “flexing” أو “تهتز” بسرعات الطرق السريعة, which would cause fatigue and eventual cracking. They also provide the primary alignment points. A minor bend in one of these brackets, while not always visible, will cause the entire المصد الأمامي فاو to appear crooked, with uneven gaps to the grille and headlights. They are secured to the chassis with the heavy-duty ‘Combination Bolt’ (CQ1461045) السحابات.

The Trim: Upper Straps (2803031-91دبليو & 2803032-91دبليو)

The ‘Left upper strap – front bumper’ (2803031-91دبليو) and ‘Right upper strap – front bumper’ (2803032-91دبليو) are the finishing components of the المصد الأمامي فاو. These are not the main “الأشرطة” that hold the bumper on, but are rather “تقليم” أو “filler” قِطَع.

Their function is primarily aesthetic and aerodynamic. They are designed to “bridge the gap” between the top edge of the main المصد الأمامي فاو and the bottom edge of the truck’s main grille or headlight assemblies.

By closing this gap, they create a smooth, uninterrupted surface for air to flow over. هذا “منطق” prevents air from being “مُحاصَر” behind the bumper, which would create aerodynamic drag and reduce fuel efficiency. These trim pieces are typically held in place by the 22 ‘Cross recessed pan head screw assembly’ (Q2360616B) السحابات, indicating they are a “non-structural” but essential part of the المصد الأمامي فاوتصميم.

نظام السحابة: A Vibration-Proof Assembly

ال المصد الأمامي فاو is held together by a large set of specialized, السحابات المقاومة للاهتزاز. هذا ليس أ “مقاس واحد يناسب الجميع” نظام.

**’Cross recessed pan head screw assembly’ (Q2360616B) – 22 وحدات:** هذه هي “light-duty” السحابات. ال “حَشد” (مزيج) design means they have a pre-installed lock washer. These are used to attach the non-structural, aesthetic parts like the ‘Upper straps’ (2803031-91دبليو) and other trim.

**’Combination Bolt’ (CQ1461045) – 8 وحدات:** هذه هي واجب ثقيل, M10 bolts. ال “مزيج” design with a captive spring-lock washer is critical. هؤلاء 8 bolts are almost certainly the main fasteners used to secure the two ‘Front bumper brackets’ (2803281-91دبليو & 2803282-91دبليو) مباشرة إلى قضبان إطار الهيكل الرئيسي للشاحنة.

**’Combination Bolt’ (CQ1460830) – 6 وحدات:** These are slightly smaller, M8 bolts. هؤلاء 6 bolts are likely used for the “structural-to-structural” connection of the المصد الأمامي فاو, attaching the main ‘Bumper left/right part assemblies’ to the steel brackets.

This three-tiered fastener system is the “منطق” that ensures the المصد الأمامي فاو is both serviceable (for the trim) and structurally sound (for the main brackets), with every connection protected against the constant vibration of a heavy-duty diesel engine.
