FAW مركز المحور الإسكان, نصف مهاوي والتجميع المنطقي من خلال رمح: لماذا هذه 18 الأجزاء الحرجة مهمة

مرحبًا بك في هذا الدليل الفني المهم حول FAW مركز المحور الإسكان, نصف مهاوي والتجميع المنطقي من خلال رمح. هذا هو الكامل “إلى الأمام” أو “middle” drive axle for the FAW Jiefang CA4251P66K24T1A3E5 6×4 جرار نصف مقطورة ديزل. This is the core component that makes the “6×4” drive system possible.

ال FAW مركز المحور الإسكان, نصف مهاوي والتجميع المنطقي من خلال رمح هو مجمع, “through-drive” المحور. إنه “منطق” is to perform two functions simultaneously: أولاً, it receives power from the main driveshaft and sends it to its own wheels via the ‘Half-Shafts’. ثانية, it passes that power *through* its differential carrier via the ‘Through-Shaft’ to the rearmost drive axle.

This in-depth guide is an essential resource for professional driveline technicians and parts specialists. سنقوم بتفكيك الكل FAW مركز المحور الإسكان, نصف مهاوي والتجميع المنطقي من خلال رمح فيه 18 مكونات صالحة للخدمة, including the main ‘Centre axle housing’, "اليسار".’ و"صحيح".’ half-shafts, and the critical ‘Through-shaft’ bearing and seal assembly.

المكون الأساسي: The ‘Centre Axle Housing’ (2501010BA6T)

أساس FAW مركز المحور الإسكان, نصف مهاوي والتجميع المنطقي من خلال رمح is the ‘Centre axle housing assembly’ (2501010BA6T). This is the main structural component, 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 truck’s suspension. 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.

A crack or bend in this FAW مركز المحور الإسكان, نصف مهاوي والتجميع المنطقي من خلال رمح (على سبيل المثال, from an impact or overloading) is a catastrophic, vehicle-ending failure. Its structural integrity is paramount.

ال “Half-Shafts”: غادر (2503081-A6T) & يمين (2503082-A6T)

ال “Half-Shafts” مكونات FAW مركز المحور الإسكان, نصف مهاوي والتجميع المنطقي من خلال رمح are the ‘Centre axle left half-shaft’ (2503081-A6T) and the ‘Centre axle right half-shaft’ (2503082-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 from the differential to the wheels. They do *not* support the weight of the vehicle. The vehicle’s weight is supported by the ‘Centre axle housing assembly’ نفسها, via the large wheel hub bearings.

هذا “full-float” design means that if a FAW مركز المحور الإسكان, نصف مهاوي والتجميع المنطقي من خلال رمح‘s shaft were to break, the wheel *will not fall off* the truck. The shafts are splined on their inner end (to engage with the differential’s “التروس الجانبية”) 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 different lengths to accommodate the central differential.

ال “Through-Shaft Logic”: Powering the 6×4

الأكثر أهمية “منطق” التابع FAW مركز المحور الإسكان, نصف مهاوي والتجميع المنطقي من خلال رمح هو “Through-Shaft.” This is what makes it a “centre” (أو “middle”) المحور. This system allows the main driveshaft to send power *through* this axle to the rearmost axle.

This is achieved with several key components:

• **’Through-shaft’ (2502161-A9T):** This is the main shaft that passes *through* the differential carrier, driven by the pinion.
• **’Centre axle output flange assembly’ (2502165-A6T):** This is the flange splined to the *end* of the through-shaft, where the inter-axle driveshaft (انظر التجمع 326) connects.
• **’Tapered roller bearing assembly’ (2502040-A6T-C00):** This massive bearing supports the through-shaft, handling the immense radial and axial loads.

This bearing is held in place by the ‘Bearing cap-through-shaft’ (2502168K5H) and its ‘Gasket-bearing cap’ (2502169K5HB1). This entire sub-assembly is then sealed by the ‘Through-shaft oil seal assembly’ (2502170-A8T-C00) and its ‘O-ring’ (CQ7345475C), which are critical for preventing gear oil from leaking out the back of the FAW مركز المحور الإسكان, نصف مهاوي والتجميع المنطقي من خلال رمح. هذا “pass-through” design is the core of the 6×4 drivetrain’s logic.

خدمة, ختم, والسحابات

ال FAW مركز المحور الإسكان, نصف مهاوي والتجميع المنطقي من خلال رمح is designed for heavy-duty service. It includes three critical service plugs:

• **’Oil filler plug’ (2401051-A0R):** ال “fill” و “level check” ميناء.
• **’Inner hex tapered magnetic screw plug’ (T62104m):** ال “بالُوعَة” سدادة. Its magnet is a key diagnostic tool, as it traps metal particles from wear, indicating the health of the FAW مركز المحور الإسكان, نصف مهاوي والتجميع المنطقي من خلال رمح.
• **’Breather plug’ (T905):** This essential vent prevents pressure from building up in the housing as it heats, which would blow out the ‘Through-shaft oil seal’ (2502170-A8T-C00) and wheel seals.

The system is sealed with ‘Gasket rings’ (CQ72324T5) for the plugs. The entire assembly is held together with high-tensile fasteners. ال 20 'مسامير شفة سداسية’ (Q1851650TF2K) are for the axle shafts, while ‘Hex head bolts’ (CQ1501445), "حشيات الربيع."’ (س40314), and the ‘Nut-pinion shaft bearing’ (2402071K5H) are used to secure the bearing caps and through-shaft flange. This robust hardware is essential for the reliability of the FAW مركز المحور الإسكان, نصف مهاوي والتجميع المنطقي من خلال رمح.
