مجموعة منطق محور العجلة الأمامية FAW: تفكيك 10 المكونات الحرجة

مرحبًا بكم في هذا التفكيك النقدي لل مجموعة منطق محور العجلة الأمامية FAW (الجزء لا. 3103601-98ر). هذا هو الكامل, load-bearing wheel-end system for the front steer axle of the FAW Jiefang CA4251P66K24T1A3E5 6×4 جرار نصف مقطورة ديزل. This assembly is the rotating foundation for the wheel and brake system.

ال مجموعة منطق محور العجلة الأمامية FAW هو متطور, pre-set “unitized” مَركَز. إنه “منطق” is to provide a low-friction, high-strength rotating mount for the front wheel. This assembly must support the entire dynamic weight of the front-end, provide the rotating surface for the ‘Front brake drum’ (3501571-98ر), and house the ‘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 مجموعة منطق محور العجلة الأمامية FAW فيه 10 مكونات صالحة للخدمة, including the main ‘Hub’ (10080596), the ‘Inner’ (10026058) and ‘Outer’ (10041099) المحامل, and the critical ‘Oil seal’ (10080107).

المكون الأساسي: The ‘Hub’ (10080596)

قلب ال مجموعة منطق محور العجلة الأمامية FAW 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” (the outer rings) 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’ (3501571-98ر) mounts to its inner face.

This ‘Hub’ is the central rotating mass of the مجموعة منطق محور العجلة الأمامية FAW, and it must be perfectly balanced and machined to prevent any “تمايل” أو “نفد,” which would cause severe vibration and uneven brake wear.

ال “Unitized” تحمل المنطق (ConMet)

ال “منطق” من هذا محددة مجموعة منطق محور العجلة الأمامية FAW 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’ (10041099):** The smaller tapered roller bearing at the outer end of the hub.
• **’Inner bearing’ (10026058):** The larger, main load-bearing tapered roller bearing at the inner end of the hub.
• **’Bearing spacer’ (10023828):** The critical component.

In a traditional مجموعة منطق محور العجلة الأمامية FAW, these two bearings are “loose.” A technician must tighten the main ‘Axle head lock nut’ (3001060AA8S-C00) to a precise, *low-torque* “التحميل المسبق” مواصفة, usually while spinning the hub. This process is difficult and a common source of errors.

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 ‘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 guesswork, dramatically increases bearing life, and simplifies service.

Critical Sealing: The ‘Oil Seal’ (10080107) and ‘Hub Cap’ (3103065AA8S-C00)

The bearings in the مجموعة منطق محور العجلة الأمامية FAW are lubricated by heavy-duty hub oil (or semi-fluid grease). The ‘Oil seal (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 مجموعة منطق محور العجلة الأمامية FAW 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 مجموعة منطق محور العجلة الأمامية FAW. 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. هذا “منطق” of easy inspection is key to preventive maintenance.

The ABS Logic: ‘ABS Ring’ (10037801)

ال “منطق” التابع مجموعة منطق محور العجلة الأمامية FAW‘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 ‘Front brake drum’ (3501571-98ر), 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 مجموعة منطق محور العجلة الأمامية FAW. A cracked or dirt-fouled ring will disable the ABS and traction control systems, اثارة ضوء تحذير.
