FAW مبيت المحور الخلفي ومجموعة نصف العمود: تحليل نقدي لها 8 المكونات الأساسية

مرحبًا بكم في هذا التحليل الفني النقدي لـ FAW مبيت المحور الخلفي ومجموعة نصف العمود. This is the complete load-bearing and power-delivery system for the rear drive axle of the FAW Jiefang CA4251P66K24T1A3E5 6×4 جرار نصف مقطورة ديزل. This assembly is the literal foundation of the “6×4” drive system.

ال FAW مبيت المحور الخلفي ومجموعة نصف العمود is a multi-part system consisting of two main functional groups: the ‘Rear axle housing assembly’ (2401010BA6T), which is the structural “هيكل عظمي” that holds the differential and bearings, and the ‘Half-Shaft’ التجميعات (2403081-A6T & 2403082-A6T) that transmit torque to the wheels.

يعد هذا الدليل المتعمق موردًا أساسيًا للفنيين المحترفين في مجموعة القيادة, مديري الأسطول, ومتخصصين في قطع الغيار. سنقوم بتفكيك الكل FAW مبيت المحور الخلفي ومجموعة نصف العمود فيه 8 مكونات صالحة للخدمة, بما في ذلك السكن الرئيسي, the individual axle shafts, the magnetic drain plug, and the critical breather valve.

المكون الأساسي: The Rear Axle Housing (2401010BA6T)

قلب ال FAW مبيت المحور الخلفي ومجموعة نصف العمود is the ‘Rear axle housing assembly’ (2401010BA6T). هذا هو العنصر الهيكلي الرئيسي, often called the “البانجو” أو “carrier.” إنها ضخمة, high-strength casting, typically made of ductile cast iron, designed to handle the entire weight of the tractor’s rear and its cargo, as well as the immense torque loads from the driveline.

This housing performs three critical functions. أولاً, هذا هو “هيكل عظمي” that provides the mounting points for the entire suspension system (leaf springs, air bags). ثانية, it is the rigid “قضية” that holds the differential (the ring and pinion gearset) in perfect, precision-machined alignment. ثالث, it acts as the “axle tubes,” extending outwards to hold the wheel hub bearings.

The housing is also a sealed oil reservoir, holding several gallons of heavy-duty gear oil to lubricate the differential. A crack or bend in this FAW مبيت المحور الخلفي ومجموعة نصف العمود (على سبيل المثال, from an impact or overloading) is a catastrophic, vehicle-ending failure. Its structural integrity is paramount.

ال “Half-Shafts”: غادر (2403081-A6T) & يمين (2403082-A6T)

ال “Half-Shaft” مكونات FAW مبيت المحور الخلفي ومجموعة نصف العمود are the ‘Rear axle left half-shaft’ (2403081-A6T) and the ‘Rear axle right half-shaft’ (2403082-A6T). هذه هي “محاور” themselves. They are solid, forged shafts made from an incredibly tough and ductile steel alloy (يحب 4340 chromoly), designed to twist slightly under extreme torque without breaking.

These are **full-floating** axles. This is a critical design feature for a heavy-duty truck. In this system, the axle shafts “يطفو” inside the housing. Their *only* job is to transmit torque. They do *not* support the weight of the vehicle. The vehicle’s weight is supported by the ‘Rear axle housing assembly’ نفسها, via the large wheel hub bearings.

هذا “full-float” design means that if a FAW مبيت المحور الخلفي ومجموعة نصف العمود‘s shaft were to break (a rare but possible event under extreme load), the wheel *will not fall off* the truck. The driver can safely pull over. The shafts are splined on their inner end (to engage with the differential’s “شمس” التروس) and flanged on their outer end, where they are secured to the wheel hub by the 20 'مسامير شفة سداسية’ (Q1851650TF2K).

The reason for a separate “غادر” و “يمين” half-shaft is simply their length. Due to the central mounting of the differential “اليقطين,” one axle shaft is always slightly longer than the other to reach the corresponding wheel hub. A worn or twisted spline on the FAW مبيت المحور الخلفي ومجموعة نصف العمود is a common failure point that will result in a “نقرة” on acceleration and an eventual loss of drive.

Lubrication and Service Logic

ال FAW مبيت المحور الخلفي ومجموعة نصف العمود contains several critical service components for its gear oil.

**1. ‘Oil filler plug’ (2401051-A0R):** هذا هو “fill” و “level check” ميناء. It is located on the side of the differential housing. A technician removes this plug and fills the axle with gear oil until the fluid is level with the bottom of this hole.

**2. ‘Inner hex tapered magnetic screw plug’ (T62104m):** هذا هو “بالُوعَة” سدادة, located at the lowest point of the FAW مبيت المحور الخلفي ومجموعة نصف العمود. إنه “magnetic” property is its most important “منطق.” The magnet actively traps microscopic metal particles that are a normal byproduct of gear wear. During an oil change, inspecting this plug gives a technician a clear “health report” of the differential. A large amount of “زغب” is normal, but large “chips” indicate a failing bearing or chipped gear tooth inside the FAW مبيت المحور الخلفي ومجموعة نصف العمود.

**3. ‘Gasket ring’ (CQ72324T5):** This is the single-use “غسالة سحق” for the magnetic drain plug. It must be replaced at every oil change to guarantee a leak-free seal.

ال “استراحة” منطق (T905)

The ‘Breather plug’ (T905) is one of the most critical, بعد بسيطة, مكونات FAW مبيت المحور الخلفي ومجموعة نصف العمود. As the differential and its oil heat up during driving, the air inside the ‘Rear axle housing assembly’ يتوسع, building pressure.

This breather plug is a one-way (or filtered) “vent.” It allows this hot, pressurized air to escape. When the axle cools, the air inside contracts, خلق فراغ. The breather allows clean air to be drawn *in*.

فشل هذا “منطق” is catastrophic. If the ‘Breather plug’ (T905) becomes clogged with mud or dirt, the expanding pressure has nowhere to go. It will force its way out past the weakest points: the axle’s pinion seal and the wheel hub seals, causing a massive oil leak. على العكس من ذلك, if the axle cools and the clogged breather creates a vacuum, it can *suck in* water and mud during a water crossing, contaminating the oil and destroying the bearings. This tiny plug is essential to the long-term health of the FAW مبيت المحور الخلفي ومجموعة نصف العمود.

نظام السحابة: (Q1851650TF2K)

ال FAW مبيت المحور الخلفي ومجموعة نصف العمود is held together by the 20 "ترباس شفة سداسية.", قضيب خشن (نوع قياسي)’ (Q1851650TF2K) السحابات. These are the bolts that secure the flanges of the ‘Left’ و"صحيح".’ half-shafts to the wheel hubs (10 bolts per side).

These are the final link in the power-delivery chain. They are responsible for transmitting 100% of the engine’s multiplied torque from the axle shaft to the wheel. هم “شفة” البراغي, which act as an integrated washer to provide a high-clamping force. They are also high-tensile (على سبيل المثال, فصل 10.9) and are often “عزم الدوران إلى العائد” (استخدام مرة واحدة) السحابات. A loose or broken axle shaft bolt will cause a “النقر” sound as the wheel turns and can lead to a total loss of power on that side of the vehicle. This hardware is a key serviceable part of the FAW مبيت المحور الخلفي ومجموعة نصف العمود.
