FAW محور العجلة المركزية الجمعية حافة الألومنيوم: تحليل نقدي ل 13 المكونات الأساسية

مرحبًا بكم في هذا التحليل الفني النقدي لـ FAW محور العجلة المركزية الجمعية حافة الألومنيوم (الجزء لا. 3104G25DA6T). هذا هو الكامل, high-performance, lightweight wheel-end system for the *centre* (أو “إلى الأمام”) محور القيادة FAW Jiefang CA4251P66K24T1A3E5 6×4 جرار نصف مقطورة ديزل.

ال FAW محور العجلة المركزية الجمعية حافة الألومنيوم هو متطور, pre-set “unitized” مَركَز. إنه “منطق” is to provide a low-friction, high-strength rotating mount for the “dual-wheel” **Aluminium Rim** setup. This assembly must support the entire dynamic *and* static payload of the trailer, house the ‘Rear brake drum’ (3502571-A6T), and contain the ‘ABS ring’ (10041090) for the anti-lock braking system.

يعد هذا الدليل المتعمق موردًا أساسيًا لفنيي مجموعة الحركة ومديري الأساطيل المحترفين. سنقوم بتفكيك الكل FAW محور العجلة المركزية الجمعية حافة الألومنيوم فيه 13 مكونات صالحة للخدمة, including the main ‘Hub’ (10045312), the ConMet ‘Bearings’ (Inner and Outer), the ‘Oil seal’ (10080112), and the critical ‘Bearing spacer’ (10045316). ال FAW محور العجلة المركزية الجمعية حافة الألومنيوم is a key component for modern fleet efficiency.

المكون الأساسي: The ‘Hub’ (10045312) – Drive vs. Steer

قلب ال FAW محور العجلة المركزية الجمعية حافة الألومنيوم is the ‘Hub’ (10045312). هذا هو العنصر الهيكلي الرئيسي, ضخمة, precision-machined casting (often ductile iron) that forms the rotating “wheel-end.” هذا “drive hub” is fundamentally different from the “steer hub” على المحور الأمامي.

While both hubs house the bearings, this rear hub has one additional, critical feature: it is internally splined. These splines are designed to engage with the splines of the ‘Half-Shaft’ (axle shaft, انظر الجمعية 400). هذه هي الطريقة FAW محور العجلة المركزية الجمعية حافة الألومنيوم receives rotational torque from the differential, which it then transmits to the wheels via the 10 ‘Wheel studs’ (10001400).

ال “Aluminium Rim” تسمية FAW محور العجلة المركزية الجمعية حافة الألومنيوم indicates this hub is designed for use with lightweight, forged aluminum wheels. هذا “منطق” is a key performance choice: aluminum rims significantly reduce **unsprung weight** (weight not supported by the suspension). This reduction allows the suspension to react faster, improving tire-to-road contact, increasing ride quality, and reducing wear. They also reduce overall vehicle weight, which can improve fuel economy and increase available payload. This assembly also provides the mounting face for the ‘Rear brake drum’ (3502571-A6T). ال FAW محور العجلة المركزية الجمعية حافة الألومنيوم is built for performance.

ال “Unitized” تحمل المنطق (ConMet System)

ال “منطق” من هذا محددة FAW محور العجلة المركزية الجمعية حافة الألومنيوم lies in its advanced, “unitized” bearing system. The parts are all sourced from ConMet (康迈公司), a leader in hub-end technology. The key components are:

• **’Outer bearing’ (10045483 / 10045313):** The two-part tapered roller bearing at the outer end of the hub. (ConMet 33019 / 33021)
• **’Inner bearing’ (10045759 / 10045314):** The larger, main load-bearing tapered roller bearing at the inner end of the hub. (ConMet 33019 / 33021)
• **’Bearing spacer’ (10045316):** The critical component that sets this assembly apart.

In a traditional FAW محور العجلة المركزية الجمعية حافة الألومنيوم, these two bearings are “loose.” A technician must tighten the main axle nut to a precise, *low-torque* “التحميل المسبق” مواصفة, usually while spinning the hub. This process is difficult, time-consuming, and a common source of errors (over-tightening leads to bearing seizure; under-tightening leads to “تمايل” and failure).

This ConMet system’s “منطق” is different. The ‘Bearing spacer’ is a precision-ground, “matched” spacer that is engineered to be the *exact* width needed to set the perfect preload. The technician installs the inner bearing, the spacer, and the outer bearing. ثم, they simply tighten the main axle nut to a very *high*, fixed torque. The spacer absorbs this torque, automatically setting the bearing preload to the perfect factory specification. This eliminates guesswork, dramatically increases bearing life, and simplifies service for the FAW محور العجلة المركزية الجمعية حافة الألومنيوم. A robust FAW محور العجلة المركزية الجمعية حافة الألومنيوم is key to fleet uptime.

Critical Sealing: The ‘Oil Seal’ (10080112) and ‘Hub Cap’ (10036508)

The bearings in the FAW محور العجلة المركزية الجمعية حافة الألومنيوم are lubricated by heavy-duty axle/gear oil. "ختم النفط". (Cummins)’ (10080112) is the single most critical component for keeping this oil *in* and keeping water, تراب, and road grime *out*.

This is a high-tech, multi-lip radial shaft seal. It is pressed into the back of the ‘Hub’ (10045312), and its flexible, spring-loaded lips ride on the ‘Seal seat’ (3104044-A6T), a polished “wear ring” on the main axle housing.

A failure of this one seal in the FAW محور العجلة المركزية الجمعية حافة الألومنيوم is a catastrophic event. If it leaks oil *out*, the ‘Inner’ and ‘Outer’ bearings will run dry, overheat, and seize, which can cause the entire wheel to lock up or detach from the vehicle. If it leaks *in*, water will contaminate the oil, causing the bearings to rust and “spall” (flake apart). This is why the ‘O-ring’ (3104066-A6T-C00) is also used to ensure the ‘Seal seat’ is locked in place.

"قابس حشو الزيت."’ (10036508) هو “hub cap” أو “قابس الزيت” that seals the *outer* end of the FAW محور العجلة المركزية الجمعية حافة الألومنيوم. هذا المكون (often with a clear “sight glass”) allows a technician to visually inspect the oil level and condition without having to disassemble the hub, which is a key service “منطق.” Proper sealing is essential for the FAW محور العجلة المركزية الجمعية حافة الألومنيوم.

The ABS Logic: ‘ABS Ring’ (10041090)

ال “منطق” التابع FAW محور العجلة المركزية الجمعية حافة الألومنيوم‘s braking system is contained in the ‘ABS ring (Cummins)’ (10041090). هذا هو “حلقة لهجة” لنظام المكابح المانعة للانغلاق.

هذا هو “toothed” metal ring that is pressed onto the ‘Hub’ (10045312). As the wheel rotates, the teeth of this ring fly past the ‘Wheel speed sensor’ (a separate part). هذا “chopping” of the magnetic field creates a digital pulse, which is sent to the truck’s ABS computer.

The ABS computer uses this pulse to know the exact rotational speed of the wheel. If the driver “panic brakes” and the computer sees this ring suddenly *stop* (indicating a locked wheel), it will instantly “مضخة” the ‘Rear brake drum’ (3502571-A6T), allowing the wheel to regain traction. هذا “مضاد للقفل” logic is a critical safety feature, and it is entirely dependent on the integrity of this ‘ABS ring’ داخل FAW محور العجلة المركزية الجمعية حافة الألومنيوم.

ال FAW محور العجلة المركزية الجمعية حافة الألومنيوم (3104G25DA6T) هو كامل, تم تجميعها مسبقًا, and pre-lubricated unit designed for minimal maintenance and maximum on-road life. Its integration of the ConMet pre-set bearing “منطق” is a significant step up from older, manually-adjusted wheel hubs. ال FAW محور العجلة المركزية الجمعية حافة الألومنيوم is truly a modern, high-performance component.
