مجموعة مسند الذراع FAW: ال 4 مكونات مهمة لدخول آمن ومأمون إلى الكابينة

Welcome to this critical safety and ergonomic analysis of the مجموعة مسند الذراع FAW. هذا هو الكامل, 4-نوع المكون, الثقيلة “assist handle” system for the cab of the FAW Jiefang CA4251P66K24T1A3E5 6×4 جرار نصف مقطورة ديزل. هذا ليس أ “راحة” مسند الذراع; it is a primary structural component. Its core “منطق” هو توفير آمنة, load-bearing hand-hold, enabling a driver to safely maintain “3-point contact” when climbing into or out of the high cab-over-engine.

ال مجموعة مسند الذراع FAW is an integral part of the vehicle’s safety and access “منطق,” working in conjunction with the ‘Wing Panel Logic Assembly’ (حَشد 622) خطوات. This system is comprised of two mirror-image ‘Armrest Assemblies’ (غادر: 5302115-D03, يمين: 5302120-D03) and a robust 14-piece fastener kit. ال “منطق” of its design is to provide an unyielding anchor point capable of supporting the full body weight of a driver, in all weather conditions.

This in-depth guide is an essential resource for body shop technicians, متخصصون في الاصطدام, and fleet safety managers. سنقوم بتفكيك الكل مجموعة مسند الذراع FAW فيه 4 الحد الأدنى المتميز للوحدة القابلة للخدمة (جامعة ولاية ميشيغان) أنواع. سنقوم بتحليل “structural core” logic of the main handles, their ergonomic and material design, والحرجة, dual-type “المضادة للاهتزاز” fastener system that secures them directly to the cab’s structural A-pillars.

جوهر 1: ال “أمان & مريح” منطق (وحدات التخزين المتنقلة 1 & 2) (ال “أطول” الوحدة النمطية)

المكونات الأساسية لل مجموعة مسند الذراع FAW are the ‘Left armrest assy’ (5302115-D03) and ‘Right armrest assy’ (5302120-D03). These are the main structural MSUs. As “غادر” و “يمين” أجزاء, they are mirror images, ولكن بهم “منطق” is identical: to provide a safe, مريح “assist handle” for cab ingress and egress.

1. ال “3-Point Contact” منطق السلامة:

هذا هو #1 “منطق” of this assembly. Slips and falls from heavy equipment are a leading cause of driver injury. Occupational safety regulations mandate a “3-point contact” rule, meaning the driver must always have two hands and one foot, or two feet and one hand, in contact with the vehicle when climbing or descending.

ال مجموعة مسند الذراع FAW هو “يُسلِّم” part of this equation. It is precisely positioned on the cab’s A-pillar to work in concert with the ‘3-stage step panel’ (حَشد 622). إنه “منطق” is to be at the perfect height to allow a driver to pull their entire body weight up, transitioning their grip from the lower handle to the upper handle as they ascend into the cab.

2. ال “مريح” منطق (تصميم):

تصميم مجموعة مسند الذراع FAW is not arbitrary. إنه “منطق” is based on ergonomics.

• قطر & Shape: The handle is molded to a specific diameter that allows for a full, قوي “power grip” even when the driver is wearing thick, insulated, or wet work gloves.
• Texture & مادة: The surface is a non-slip, “pebbled” أو “stippled” texture. هذا “منطق” provides maximum friction, even when the handle is covered in rain, الثلج, or diesel fuel.
• Angle & التخليص: The handle is mounted at a comfortable angle and provides several inches of “clearance” from the cab’s body, ensuring the driver’s knuckles do not get scraped or pinched.

جوهر 2: ال “النواة الهيكلية” المنطق المادي

A common misconception is that the مجموعة مسند الذراع FAW is just a piece of plastic. This is incorrect. ال “منطق” of its construction is a “الصلب في البوليمر” تصميم, similar to a modern steering wheel.

The Steel “Armature”: صحيح “منطق” of this MSU is a hidden internal structure. Inside the polymer molding is a heavy-duty, الصلب المصنعة “حديد التسليح” أو “core.” This steel core provides the actual structural strength. This core has the mounting plates with the 7 bolt holes, and it is this steel that is fastened directly to the cab’s structural ‘Welded Cab Assembly’ (حَشد 617) عمود.

The Polymer “الإفراط في العفن”: The plastic that the driver touches is an “over-mold.” هذا “منطق” is what provides all the ergonomic and comfort benefits:

• Thermal Break: The polymer is a “thermal break.” It prevents the driver from grabbing bare, freezing-cold steel in a -30°C winter or a painfully hot, sun-baked steel bar in a +50°C summer.
• Corrosion Proofing: The over-mold provides a 100% waterproof and airtight seal *around* the steel core, صنع مجموعة مسند الذراع FAW completely immune to rust.
• تخميد الاهتزاز: The softer polymer helps to damp high-frequency “شرب حتى الثمالة” from the engine, making it more comfortable to hold.

As MSUs, these are high-wear items. They are replaced when the outer polymer is cracked (exposing the steel core), or if the unit is bent or broken in a collision.

جوهر 3: ال “المضادة للاهتزاز” المنطق السحابي (وحدات التخزين المتنقلة 3 & 4)

هذه المجموعة الأخيرة من وحدات MSU هي “منطق” that ensures the مجموعة مسند الذراع FAW stays “rock solid” for the life of the truck. This system is subjected to the constant “سحب” force of drivers *and* the constant, عالية التردد “شرب حتى الثمالة” of the diesel engine.

ال “منطق السحابة” is to use 14 المجموع “براغي الجمع,” split into two different grip-lengths.

جامعة ولاية ميشيغان 3: "الترباس المختلط."’ (CQ1460816F6) – الكمية 6

جامعة ولاية ميشيغان 4: "الترباس المختلط."’ (CQ1460825F6) – الكمية 8

ال “منطق” ل 14 total bolts means each armrest (اليسار واليمين) is secured by **seven** bolts. This is a massively over-engineered, high-strength connection, proving this is a structural, load-bearing component.

ال “مزيج” (مزيج) logic is the most critical feature. هذه ليست مسامير بسيطة. They have a *captive, غسالة القفل المرفقة مسبقًا* (على سبيل المثال, غسالة مسننة أو ربيعية) under the head. هذا “منطق” يكون 100% about anti-vibration.

The lock washer bites into the steel armature of the handle and the steel A-pillar of the cab, creating constant tension. This makes it physically impossible for the bolt to back out or loosen from vibration. This is what prevents the مجموعة مسند الذراع FAW from developing a “wiggle” أو “حشرجة الموت” over time, which would lead to a catastrophic shear failure. The two different part numbers (CQ1460816F6 and CQ1460825F6) simply refer to different lengths, as the bolts must pass through different thicknesses of the A-pillar’s reinforced structure.
