FAW محور العجلة الأمامية الجمعية حافة الألومنيوم: التركيز النقدي على 10 مكونات قابلة للخدمة

مرحبًا بك في هذا الدليل الفني المهم حول FAW محور العجلة الأمامية الجمعية حافة الألومنيوم (الجزء لا. 3103601-91دبليو). هذا هو الكامل, high-performance, lightweight wheel-end system for the front steer axle of the FAW Jiefang CA4251P66K24T1A3E5 6×4 جرار نصف مقطورة ديزل.

ال FAW محور العجلة الأمامية الجمعية حافة الألومنيوم هو متطور, non-drive assembly. إنه “منطق” is to provide a low-friction, high-strength rotating mount for the front wheel, while also housing the ‘Brake drum’ (3501571-54دبليو) and the critical ‘ABS ring’ (10037801) for the anti-lock braking system.

This in-depth guide is an essential resource for professional wheel-end technicians and fleet managers. سنقوم بتفكيك الكل FAW محور العجلة الأمامية الجمعية حافة الألومنيوم فيه 10 مكونات صالحة للخدمة, including the main ‘Hub’ (10080596), the ‘Outer bearing’ (10041099), the ‘Inner bearing’ (10026058), and the critical ‘Oil seal’ (10080107).

المكون الأساسي: The ‘Hub’ (10080596) and ‘Rim’

قلب ال FAW محور العجلة الأمامية الجمعية حافة الألومنيوم is the ‘Hub’ (10080596). هذا هو العنصر الهيكلي الرئيسي, ضخمة, precision-machined casting (often ductile iron) that forms the rotating “wheel-end.” This is *not* the “rim” (the part the tyre mounts to), ولكن “مَركَز” that the rim bolts *onto*.

This ‘Hub’ has several critical functions. أولاً, it houses the “races” for the ‘Outer bearing’ (10041099) and ‘Inner bearing’ (10026058). ثانية, إنه يتميز 10 ‘Wheel studs’ (10023593) that the wheel is bolted to. ثالث, the ‘Brake drum’ (3501571-54دبليو) mounts to its inner face.

ال “Aluminium Rim” جزء من FAW محور العجلة الأمامية الجمعية حافة الألومنيوم refers to the “عجلة” نفسها (مثل الجزء رقم. 3101015A4E from Assembly 512, which mounts to this hub). Using an aluminum rim instead of steel is a “منطق” choice for reducing **unsprung weight**. Lighter wheels respond faster to bumps, improving ride quality and steering response. They also reduce overall vehicle weight, improving fuel economy. This entire assembly, including the ‘Hub cap assembly’ (3103065AA8S-C00), is the complete rotating mass.

ال “منطق”: نظام تحمل (داخلي 10026058 & الخارجي 10041099)

ال “منطق” التابع FAW محور العجلة الأمامية الجمعية حافة الألومنيوم is to allow a multi-ton wheel to spin freely with almost zero friction. This is achieved by a “unitized” bearing system from Cummins (康迈). تفاصيل قائمة الأجزاء:

• **’Outer bearing (Cummins)’ (10041099):** The smaller bearing at the outer end of the hub.
• **’Inner bearing (Cummins)’ (10026058):** The larger, main load-bearing bearing at the inner end of the hub.
• **’Bearing spacer (Cummins)’ (10023828):** The critical spacer.

These are **tapered roller bearings**, designed to handle the immense radial (vertical weight) ومحوري (side-load from cornering) القوات. In a traditional FAW محور العجلة الأمامية الجمعية حافة الألومنيوم, these two bearings are “مرتخي,” and a technician must tighten the ‘Axle head lock nut’ (3001060AA8S-C00) to a precise, low torque to set the “bearing preload.”

لكن, this ConMet (康迈) system is different. The ‘Bearing spacer’ (10023828) is a precision-ground, “matched” spacer. إنه “منطق” هو إنشاء “unitized” مَركَز. The technician installs the bearings, the spacer, and then tightens the ‘Axle head lock nut’ to a very high, fixed torque. The *spacer* absorbs this torque, automatically setting the bearing preload to the perfect factory specification. This eliminates human error, increases service life, and is a key “منطق” of the modern FAW محور العجلة الأمامية الجمعية حافة الألومنيوم.

Critical Sealing: The ‘Oil Seal’ (10080107)

The bearings in the FAW محور العجلة الأمامية الجمعية حافة الألومنيوم are lubricated by heavy-duty hub oil. "ختم النفط". (Cummins)’ (10080107) is the single most critical component for keeping this oil *in* and keeping water and dirt *out*.

This is a high-tech, multi-lip radial shaft seal. It is pressed into the back of the ‘Hub’ (10080596), and its flexible, spring-loaded lips ride on a polished “wear ring” on the main axle spindle (من الجمعية 510).

A failure of this one seal in the FAW محور العجلة الأمامية 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* (على سبيل المثال, in heavy rain or a puddle), water will contaminate the oil, causing the bearings to rust and “spall” (flake apart), leading to the same failure.

The ‘Hub cap assembly’ (3103065AA8S-C00) seals the *outer* end of the FAW محور العجلة الأمامية الجمعية حافة الألومنيوم. It is a sealed cap with a clear “sight glass,” allowing a technician to visually inspect the oil level and condition without having to disassemble the hub.

The ABS Logic: ‘ABS Ring’ (10037801)

ال “منطق” التابع FAW محور العجلة الأمامية الجمعية حافة الألومنيوم‘s braking system is contained in the ‘ABS ring (Cummins)’ (10037801). هذا هو “حلقة لهجة” لنظام المكابح المانعة للانغلاق.

هذا هو “toothed” metal ring that is pressed onto the ‘Hub’ (10080596). As the wheel rotates, the teeth of this ring fly past the ‘Wheel speed sensor’ (3550360-6ق, من الجمعية 510). 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 ‘Brake drum’ (3501571-54دبليو), 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 الأمامية الجمعية حافة الألومنيوم. A cracked or dirt-fouled ring will disable the ABS.
