فاو J6P المحور الأول: تفكيك 8 الأجزاء المهمة لإدخال عزم الدوران الخالي من العيوب

مرحبا بكم في هذا التفكيك المتعمق لل فاو J6P المحور الأول (عمود إدخال علبة التروس), a core component of the CA10TA160M transmission for the FAW Jiefang CA3250P66K2L1T1E 6×4 تفريغ الشاحنة. هذا الدليل مخصص للفنيين, تحليل 8 critical components that make up the complete فاو J6P المحور الأول حَشد, from the shaft itself to its essential bearings.

ال فاو J6P المحور الأول هو “front door” من علبة التروس. Its logic is to receive 100% of the engine’s power from the clutch and transfer it to the countershafts. Its integrity, تنسيق, and sealing are paramount for a quiet, موثوق, and leak-free transmission. This guide explores each component’s logic.

جوهر 1: ال “رمح & محرك العتاد” منطق (The FAW J6P First Axis)

تمثل هذه المجموعة “العمود الفقري” و “الإخراج” التابع فاو J6P المحور الأول حَشد. It is responsible for both receiving power from the clutch and delivering it to the gearbox’s internal gear train.

1. عنصر: ‘First shaft – علبة التروس’ (1701112-A1K / 1701112-A7G)
هذا (شركات 6) is the primary shaft, ال فاو J6P المحور الأول نفسها. إنها واحدة, heavy-duty component, precision-machined from hardened steel to withstand immense torsional forces. Its logic is to act as the “كوبري” between the engine’s clutch and the transmission’s countershafts.

ال Input Spline Logic هي وظيفتها الأولى. The front end of the shaft (projecting into the bellhousing) is externally splined. These splines mate perfectly with the internal splines of the ‘Clutch driven plate’ (clutch disc). هذا هو “مدخل” نقطة, أين 100% of the engine’s torque is transferred to the فاو J6P المحور الأول.

ال Shaft Support Logic defines its middle section. This smooth, machined surface is where the main ‘Ball bearing’ (شركات 2) يتم الضغط عليه, supporting the entire shaft assembly within the gearbox housing. The ‘Oil seal’ (شركات 1) also rides on this surface.

The two part numbers (A1K and A7G) likely indicate a minor design change, material specification, or supersession. المذكرة “(Rotates with 1601010D76A)” is a bit confusing, as 1601010D76A is the clutch housing; this shaft rotates *with the clutch disc*, not the housing. الوظيفة الأساسية لل فاو J6P المحور الأول is to spin *independently* of the housing when the clutch is disengaged.

2. عنصر: ‘Input gear – first shaft’ (1701121-A7G)
هذا (شركات 8) is the main drive gear for the entire CA10TA160M transmission. إنه “الإخراج” التابع فاو J6P المحور الأول حَشد. This gear is either pressed or splined onto the rear of the ‘First shaft’ (شركات 6) and is considered an integral part of its assembly.

ال منطق شبكة ثابت هي وظيفتها. This gear’s teeth are in constant, permanent mesh with the main drive gear(s) on the transmission’s countershaft(s). Any time the clutch is engaged and the فاو J6P المحور الأول is spinning, this gear is spinning and actively driving the countershafts. This provides the power input to the entire gear train.

جوهر 2: ال “Pilot & تنسيق” منطق (البطانة)

This component is a small but dimensionally critical part of the فاو J6P المحور الأول. Its logic is to ensure perfect alignment between the spinning input shaft and the separate, concentric mainshaft.

1. عنصر: "جلبة."’ (1701111-A7G)
هذا (شركات 7) هو “pilot bushing” أو “spigot bearing.” إنها صغيرة, hollow cylinder, typically made of bronze or a similar low-friction alloy. It is pressed into a precisely-bored recess in the *rear* end of the ‘Input gear’ (شركات 8) or ‘First shaft’ (شركات 6).

ال منطق التركيز is its sole purpose. The transmission’s mainshaft (which holds all the gears) is a separate shaft that needs to be perfectly aligned with the فاو J6P المحور الأول. ال “نصيحة” of this mainshaft slides *into* this ‘Bushing’.

This bushing acts as a crucial support, السماح ل فاو J6P المحور الأول to spin around the mainshaft tip (when the clutch is disengaged) without any “تمايل” أو “runout.” A worn-out pilot bushing (شركات 7) will cause severe vibration, difficulty in shifting, and will rapidly destroy the mainshaft bearings and synchronizers.

جوهر 3: ال “تحمل الرئيسي & ختم” منطق (Front Assembly)

This group is the primary “gateway” between the فاو J6P المحور الأول and the outside world. It is responsible for supporting the entire shaft assembly and, الأهم من ذلك, keeping the oil inside the gearbox.

1. عنصر: ‘Deep groove ball bearing with stop ring’ (6212-ZNBR/C3YB2)
هذا (شركات 2) is the main bearing for the فاو J6P المحور الأول. This is a high-load, precision ball bearing that is pressed onto the ‘First shaft’ (شركات 6) and then fits into the main bore of the ‘Gearbox Housing’.

ال دعم المنطق is clear: it supports the radial (أعلى / أسفل) and axial (in/out) loads placed on the فاو J6P المحور الأول by the clutch and the gear mesh. The ‘C3’ designation indicates a specific internal clearance, designed to accommodate the high temperatures and thermal expansion inside a gearbox.

ال Stop Ring Logic (ZNBR) أمر بالغ الأهمية. This bearing has a built-in “snap ring” on its *outer* race. This ring fits into a groove in the gearbox housing, physically locking the bearing in place and preventing the entire فاو J6P المحور الأول from moving forward or backward.

2. عنصر: ‘Oil seal – first shaft’ (1701135-A7G)
هذا (شركات 1) is the main input shaft oil seal. إنه أ “no-leak” عنصر, typically pressed into the ‘Bearing cover’ (part of the gearbox housing) which is located *in front* of the main bearing (شركات 2).

ال منطق الختم is to keep two different environments separate. ال “lip” of this seal rides on the spinning surface of the فاو J6P المحور الأول, keeping the high-temperature gear oil *inside* the gearbox. معًا, it keeps the “جاف” bellhousing free of oil, تراب, and contaminants.

A failure of this one seal is catastrophic. It will leak gear oil directly onto the clutch assembly. This oil will saturate the clutch disc, causing massive slippage, أ “burning clutch” smell, and a complete loss of power. It is a primary service item during any فاو J6P المحور الأول or clutch service.

جوهر 4: ال “Rear Retention & Shimming” منطق

This final group of components is responsible for the precise positioning of the فاو J6P المحور الأول and its associated bearings and gears. Their logic is all about managing “نهاية اللعب” و “clearances.”

1. ال “تحمل الخلفي” مجموعة (شركات 3 & 4)
تشمل هذه المجموعة: "حلقة المفاجئة." – أول محمل خلفي رمح’ (1701131-A7G, 1701132-A7G, إلخ.) و "طوقا". – أول محمل خلفي رمح’ (1701123-A7G).

ال Shimming Logic is the function of this group. ال فاو J6P المحور الأول must have a tiny, precise amount of “نهاية اللعب” (in-and-out movement), often just a few thousandths of an inch. Too little, and thermal expansion will destroy the bearings. Too much, and the gear mesh will be incorrect.

The four different ‘Snap rings’ (شركات 3) are not used all at once. They are a “shim pack.” A technician measures the gap and selects the *one* ‘Snap ring’ with the correct thickness to achieve the perfect end play. الحشية’ (شركات 4) is part of this calculation, setting the position of the bearing race. This is a high-precision task for a علبة التروس فاو J6P rebuild.

2. ال “Gear Hub” مجموعة (شركات 5)
This component is the ‘Snap ring – gear hub’ (1701314-A7G). This is a different type of snap ring.

ال منطق تحديد المواقع هي وظيفتها. This snap ring (شركات 5) fits into a groove machined directly *on* the فاو J6P المحور الأول (شركات 6). Its purpose is to act as a “توقف صعب” أو “locator.” It ensures that the ‘Input gear’ (شركات 8) or a synchronizer hub slides onto the shaft and stops at the exact correct position, ensuring perfect alignment with the countershaft gears.
