FAW J6P Вторая ось: Деконструкция 14 Важные детали для безупречной производительности редуктора

Добро пожаловать в эту критическую деконструкцию FAW J6P Вторая ось, also known as the mainshaft, for the CA10TA160M gearbox in the FAW Jiefang CA3250P66K2L1T1E 6×4 самосвал. This technical guide analyzes the 14 components that make up the complete FAW J6P Вторая ось сборка, which is the heart of the transmission’s “выход” логика.

The FAW J6P Вторая ось is the output shaft of the main 5-speed gear case. Its logic is to hold all the “управляемый” шестерни (1st-4th, Reverse) and the synchronizer sleeves that lock them. The integrity of this one shaft and its components is directly responsible for every gear shift and all power delivery to the wheels.

Основной 1: The “Вал & Gear Set” Логика (The FAW J6P Second Axis)

Эта группа представляет “spine” и “driven gears” of the main gearbox. The FAW J6P Вторая ось is the component that the driver is “подключение” to when they select a gear.

1. Компонент: ‘Second axis’ (1701301-A7G)
Этот (Комп 1) is the ‘Second axis’ сам, the mainshaft. Это длинный, heavy-duty shaft, precision-machined from hardened steel with multiple steps and grooves. Its logic is to act as the central “spine” for all the main driven gears.

The Логика выравнивания имеет решающее значение. The front “tip” of this FAW J6P Вторая ось is supported by the pilot bushing *inside* the ‘First Axis’ (input shaft). The rear of the shaft is supported by a large bearing in the back of the gearbox case. This two-point support keeps it perfectly concentric.

The Gear Carrier Logic is its main function. The “шаги” on the shaft are smooth, hardened surfaces on which all the free-spinning gears (Комп 5, 10, 12, 13, 14) ride, usually on needle bearings. The “splined” sections are where the ‘Sliding gear sleeves’ (Комп 8) установлены, which are the parts that lock the gears to the FAW J6P Вторая ось.

2. The Driven Gears (Комп 5, 10, 12, 13, 14)
В эту группу входят: ‘Reverse gear’ (Комп 5), ‘First gear’ (Комп 10), ‘Second gear’ (Комп 12), ‘Third gear’ (Комп 13), and ‘Fourth gear’ (Комп 14).

The Freewheeling Logic is the key concept. All five of these “driven gears” are in *constant mesh* with their respective drive gears on the countershaft. Однако, they are *not* fixed to the FAW J6P Вторая ось. They all spin freely on the shaft at different speeds.

When the driver selects “3третья передача,” they are *not* moving the gear itself. They are moving a ‘Sliding gear sleeve’ (Комп 8) к “замок” the ‘Third gear’ (Комп 13) к FAW J6P Вторая ось. At that moment, power flows from the countershaft, through the now-locked Comp 13, and out through the FAW J6P Вторая ось.

Основной 2: The “Engagement” Логика (Sleeves & Keys)

This group contains the components that perform the physical “locking” of the gears to the FAW J6P Вторая ось. This is the core of the synchronizer assembly.

1. Компонент: ‘Sliding gear sleeve’ (1701316-A7G) – Кол-во 3
Этот (Комп 8) is the ‘Sliding gear sleeve’. There are three of them, likely for the 1-2 сдвиг, а 3-4 сдвиг, and the Reverse shift. This is the component that the driver’s shift fork physically slides back and forth on the splines of the FAW J6P Вторая ось.

The Логика блокировки это его функция. The ‘sleeve’ has internal splines that match the FAW J6P Вторая ось. When the driver shifts, this sleeve slides over a set of external “зубы собаки” on the side of the target gear (НАПРИМЕР., ‘First gear’, Комп 10). This creates a solid, positive, non-slip lock, making the gear and the shaft spin as one unit.

2. The “Detent Key” Группа (Комп 3, 4)
В эту группу входят: ‘Three-sided key’ (Комп 3) and ‘Snap ring – трехсторонний ключ’ (Комп 4). Это “synchronizer key” или “strut.”

The Detent Logic is the function of the ‘Three-sided key’ (Комп 3). This small key sits in a groove in the synchronizer hub (which is splined to the FAW J6P Вторая ось) and is pushed outwards by a spring (нет в списке) into a groove *inside* the ‘Sliding gear sleeve’ (Комп 8).

This key is what creates the “neutral” position for the sleeve. Это обеспечивает “snap” и “click” feeling in the gear lever. The ‘Snap ring’ (Комп 4) is a small retainer that holds this key in its slot, preventing it from falling out during assembly or operation.

Основной 3: The “Positioning & Проставка” Логика (Шайбы)

This final group of components is arguably the most critical for a long-lasting, тихий FAW J6P Вторая ось. Their logic is to precisely control the “end play” and spacing of all the spinning gears.

1. The “Reverse Gear” Spacer Group (Комп 6, 7)
В эту группу входят: ‘Positioning washer – задняя передача’ (Комп 6) and ‘Limiting washer – задняя передача’ (Комп 7). These are the dedicated spacers for the ‘Reverse gear’ (Комп 5).

The Thrust Logic это их функция. The ‘Positioning washer’ (Комп 6) likely sits behind the gear, setting its base position on the FAW J6P Вторая ось. The ‘Limiting washer’ (Комп 7) sits on the other side. Вместе, these washers create a “бутерброд” that controls the gear’s “axial play” (fore-and-aft movement). This precise spacing is essential for proper engagement with the reverse idler gear and the synchronizer sleeve.

2. The “Main Gear” Spacer Group (Комп 9, 11)
В эту группу входят: ‘Limiting washer – механизм’ (Комп 9, Кол-во 4) and ‘Inter-shaft limiting washer’ (Комп 11, Кол-во 2).

The Spacer Logic is the job of the ‘Limiting washers’ (Комп 9). These four washers are the “проставки” that sit on the FAW J6P Вторая ось *between* the free-spinning gears (НАПРИМЕР., between 1st and 2nd, 2nd and 3rd, и т. д.). They prevent the hardened gears from rubbing directly against each other, which would generate immense heat and destructive metal particles.

The Thrust Bearing Logic is the job of the ‘Inter-shaft limiting washers’ (Комп 11). These are likely the main “thrust washers” for the entire gear set, located at the front and back of the gear stack. They absorb the massive axial forces generated by the helical-cut gears, protecting the FAW J6P Вторая ось bearings from being destroyed.

3. Компонент: ‘Spring cylindrical pin’ (Q5280310)
Этот (Комп 2) is a ‘Spring cylindrical pin’, also known as a “roll pin.” Его Логика блокировки is to act as a secure, vibration-proof fastener. It is likely used to lock the main shift rail (which moves the forks) на месте, or to secure a synchronizer hub (which holds Comp 3) к FAW J6P Вторая ось, preventing it from rotating or sliding.
