FAW محور العجلة الخلفية المنطق الجمعية عجلة الصلب: ال 13 المكونات الهامة في الداخل

مرحبًا بك في هذا الدليل الفني المهم حول FAW محور العجلة الخلفية المنطق الجمعية عجلة الصلب (الجزء لا. 3104G24DA6T). هذا هو الكامل, الحاملة “wheel-end” system for the rear *drive axles* of the FAW Jiefang CA4251P66K24T1A3E5 6×4 جرار نصف مقطورة ديزل. This assembly is the final link in transmitting torque to the road.

ال FAW محور العجلة الخلفية المنطق الجمعية عجلة الصلب هو “unitized” hub designed for a heavy-duty drive axle. إنه “منطق” is to provide a low-friction, high-strength rotating mount for the “dual-wheel” **Steel Wheel** setup, while also being internally splined to accept the half-shaft (axle shaft) from the differential.

This in-depth guide is an essential resource for professional driveline technicians and fleet managers. سنقوم بتفكيك الكل FAW محور العجلة الخلفية المنطق الجمعية عجلة الصلب فيه 13 مكونات صالحة للخدمة, including the main ‘Hub’ (10045312), the ConMet ‘Bearings’ (Inner and Outer), the ‘Rear brake drum’ (3502571-A6T), and the critical ‘ABS ring’ (10041090).

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

قلب ال FAW محور العجلة الخلفية المنطق الجمعية عجلة الصلب is the ‘Hub’ (10045312). This is the main structural component, a massive, precision-machined casting of ductile iron. هذا “drive hub” is fundamentally different from the “steer hub” on the front axle.

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, see Assembly 328 أو 400). This is how the FAW محور العجلة الخلفية المنطق الجمعية عجلة الصلب receives rotational torque from the differential, which it then transmits to the wheels via the 10 ‘Wheel studs’ (10001399).

ال “Steel Wheel” designation of the FAW محور العجلة الخلفية المنطق الجمعية عجلة الصلب indicates this hub is designed for the high-clamping-force and durability requirements of steel dual-wheels (“duallies”), which are the standard for maximum load capacity on a drive axle. This assembly also provides the mounting face for the ‘Rear brake drum’ (3502571-A6T).

ال “Unitized” Bearing Logic (ConMet System)

ال “منطق” of this specific FAW محور العجلة الخلفية المنطق الجمعية عجلة الصلب 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.
• **’Inner bearing’ (10045759 / 10045314):** The larger, main load-bearing tapered roller bearing at the inner end of the hub.
• **’Bearing spacer’ (10045316):** The critical component that sets this assembly apart.

In a traditional FAW محور العجلة الخلفية المنطق الجمعية عجلة الصلب, these two bearings are “loose.” A technician must tighten the main axle nut to a precise, *low-torque* “preload” 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 “wobble” 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. Then, 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 الخلفية المنطق الجمعية عجلة الصلب.

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

The bearings in the FAW محور العجلة الخلفية المنطق الجمعية عجلة الصلب are lubricated by heavy-duty axle/gear oil. The ‘Oil seal (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 الخلفية المنطق الجمعية عجلة الصلب 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.

The ‘Oil filler plug’ (10036508) هو “hub cap” أو “قابس الزيت” that seals the *outer* end of the FAW محور العجلة الخلفية المنطق الجمعية عجلة الصلب. 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 “logic.”

The ABS Logic: ‘ABS Ring’ (10041090)

ال “منطق” التابع FAW محور العجلة الخلفية المنطق الجمعية عجلة الصلب‘s braking system is contained in the ‘ABS ring (Cummins)’ (10041090). هذا هو “حلقة لهجة” for the Anti-lock Braking System.

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 “anti-lock” logic is a critical safety feature, and it is entirely dependent on the integrity of this ‘ABS ring’ within the FAW محور العجلة الخلفية المنطق الجمعية عجلة الصلب.
