FAW J6P Первая ось: Деконструкция 8 Важнейшие детали для безупречного крутящего момента

Добро пожаловать в эту глубокую деконструкцию FAW J6P Первая ось (Gearbox Input Shaft), a core component of the CA10TA160M transmission for the FAW Jiefang CA3250P66K2L1T1E 6×4 самосвал. Это руководство предназначено для технических специалистов, анализируя 8 critical components that make up the complete FAW J6P Первая ось сборка, from the shaft itself to its essential bearings.

The FAW J6P Первая ось это “входная дверь” коробки передач. Its logic is to receive 100% of the engine’s power from the clutch and transfer it to the countershafts. Its integrity, выравнивание, and sealing are paramount for a quiet, надежный, and leak-free transmission. This guide explores each component’s logic.

Основной 1: The “Вал & Приводная шестерня” Логика (The FAW J6P First Axis)

Эта группа представляет “позвоночник” и “выход” принадлежащий FAW J6P Первая ось сборка. It is responsible for both receiving power from the clutch and delivering it to the gearbox’s internal gear train.

1. Компонент: ‘First shaft – коробка передач’ (1701112-A1K / 1701112-A7G)
Этот (Комп 6) is the primary shaft, а FAW J6P Первая ось сам. Это сингл, heavy-duty component, precision-machined from hardened steel to withstand immense torsional forces. Its logic is to act as the “мост” between the engine’s clutch and the transmission’s countershafts.

The Input Spline Logic это его первая функция. 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). Это “вход” point, where 100% of the engine’s torque is transferred to the FAW J6P Первая ось.

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

The two part numbers (A1K and A7G) likely indicate a minor design change, material specification, or supersession. Примечание “(Rotates with 1601010D76A)” is a bit confusing, as 1601010D76A is the clutch housing; this shaft rotates *with the clutch disc*, not the housing. Основная функция FAW J6P Первая ось is to spin *independently* of the housing when the clutch is disengaged.

2. Компонент: ‘Input gear – первый вал’ (1701121-A7G)
Этот (Комп 8) is the main drive gear for the entire CA10TA160M transmission. Это “выход” принадлежащий FAW J6P Первая ось сборка. This gear is either pressed or splined onto the rear of the ‘First shaft’ (Комп 6) and is considered an integral part of its assembly.

The Constant Mesh Logic это его функция. This gear’s teeth are in constant, permanent mesh with the main drive gear(с) on the transmission’s countershaft(с). Any time the clutch is engaged and the FAW J6P Первая ось is spinning, this gear is spinning and actively driving the countershafts. This provides the power input to the entire gear train.

Основной 2: The “Pilot & Выравнивание” Логика (Втулка)

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

1. Компонент: 'Втулка’ (1701111-A7G)
Этот (Комп 7) является а “pilot bushing” или “spigot bearing.” Это небольшой, 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’ (Комп 8) or ‘First shaft’ (Комп 6).

The Concentricity Logic это его единственная цель. The transmission’s mainshaft (which holds all the gears) is a separate shaft that needs to be perfectly aligned with the FAW J6P Первая ось. The “tip” of this mainshaft slides *into* this ‘Bushing’.

This bushing acts as a crucial support, позволяя FAW J6P Первая ось to spin around the mainshaft tip (when the clutch is disengaged) without any “колебаться” или “runout.” A worn-out pilot bushing (Комп 7) will cause severe vibration, difficulty in shifting, and will rapidly destroy the mainshaft bearings and synchronizers.

Основной 3: The “Main Bearing & Тюлень” Логика (Front Assembly)

This group is the primary “gateway” between the FAW J6P Первая ось and the outside world. It is responsible for supporting the entire shaft assembly and, самое главное, keeping the oil inside the gearbox.

1. Компонент: ‘Deep groove ball bearing with stop ring’ (6212-ZNBR/C3YB2)
Этот (Комп 2) is the main bearing for the FAW J6P Первая ось. This is a high-load, precision ball bearing that is pressed onto the ‘First shaft’ (Комп 6) and then fits into the main bore of the ‘Gearbox Housing’.

The Support Logic is clear: it supports the radial (вверх/вниз) and axial (in/out) loads placed on the FAW J6P Первая ось 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.

The Stop Ring Logic (ZNBR) имеет решающее значение. 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 FAW J6P Первая ось from moving forward or backward.

2. Компонент: ‘Oil seal – первый вал’ (1701135-A7G)
Этот (Комп 1) is the main input shaft oil seal. Это “no-leak” компонент, typically pressed into the ‘Bearing cover’ (part of the gearbox housing) which is located *in front* of the main bearing (Комп 2).

The Логика уплотнения is to keep two different environments separate. The “lip” of this seal rides on the spinning surface of the FAW J6P Первая ось, keeping the high-temperature gear oil *inside* the gearbox. Одновременно, it keeps the “сухой” bellhousing free of oil, пыль, 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, а “burning clutch” smell, and a complete loss of power. It is a primary service item during any FAW J6P Первая ось or clutch service.

Основной 4: The “Rear Retention & Shimming” Логика

This final group of components is responsible for the precise positioning of the FAW J6P Первая ось and its associated bearings and gears. Their logic is all about managing “end play” и “clearances.”

1. The “Rear Bearing” Группа (Комп 3 & 4)
В эту группу входят: ‘Snap ring – Первый вал задний подшипник’ (1701131-A7G, 1701132-A7G, и т. д.) and ‘Gasket – Первый вал задний подшипник’ (1701123-A7G).

The Shimming Logic is the function of this group. The FAW J6P Первая ось must have a tiny, precise amount of “end play” (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’ (Комп 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. «Прокладка»’ (Комп 4) is part of this calculation, setting the position of the bearing race. This is a high-precision task for a Коробка передач ФАВ J6P rebuild.

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

The Логика позиционирования это его функция. This snap ring (Комп 5) fits into a groove machined directly *on* the FAW J6P Первая ось (Комп 6). Its purpose is to act as a “hard stop” или “locator.” It ensures that the ‘Input gear’ (Комп 8) or a synchronizer hub slides onto the shaft and stops at the exact correct position, ensuring perfect alignment with the countershaft gears.
