Клапан FAW J6P & Шланговая сборка: Деконструкция 13 Важные детали для безупречного управления переключением диапазонов

Добро пожаловать в эту критическую деконструкцию Клапан FAW J6P, Шланг, and Connector assembly, the complete pneumatic control system for the CA10TA160M 10-speed gearbox. This system is essential for the FAW Jiefang CA3250P66K2L1T1E 6×4 самосвал. This guide deconstructs all 13 part types, from the main Клапан FAW J6P to the hoses and filters.

Этот Клапан FAW J6P assembly is the “pneumatic brain” of the Hi/Lo range shifter. Its logic is to interpret the driver’s signal and safely route compressed air to the ‘Auxiliary Gearbox Range Cylinder’. It is a complete logic circuit, ensuring that range shifts only happen when conditions are correct, protecting the transmission from damage.

Основной 1: The “Follower Valve” Логика (The Pneumatic Actuator)

This group represents the primary “logic gate” и “привод” of the entire pneumatic circuit. It receives a signal and performs the main action of directing high-pressure air to the range cylinder. This is the core of the Клапан FAW J6P система.

1. Компонент: ‘Follower valve assy’ (1702320-A7G)
Этот (Комп 1) является основным “follower valve,” also known as a slave valve. This is the workhorse of the Клапан FAW J6P сборка. It is a high-volume air relay.

The Pilot Logic is its key function. This valve does *not* receive the full-volume air supply from the driver’s in-cab Hi/Lo switch. Вместо, it receives a very low-volume “pilot” сигнал. This signal acts as a “trigger.”

When this pilot signal is received, it internally opens a much larger “poppet” или “spool” клапан. This main valve then releases a high-volume, high-pressure flow of air (НАПРИМЕР., 120 пси) directly from the truck’s main air tanks. This air is then sent to the ‘Auxiliary Gearbox Range Cylinder’ to perform the shift. This relay logic makes the Клапан FAW J6P system respond instantly.

2. Компонент: «Прокладка – follower valve assy’ (1702321-A7G)
Этот (Комп 2) is the critical static seal for the ‘Follower valve’ (Комп 1). It is a precision-cut gasket that sits between the valve body and the gearbox housing.

The Dual-Seal Logic is its purpose. This gasket, when compressed by the four ‘Hex flange bolts’ (Комп 7), must do two jobs: 1) It must provide a perfect, high-pressure *air seal* for the pneumatic passages running from the housing into the valve. 2) It must provide a perfect *oil seal* to keep the high-temperature gear oil *inside* the gearbox housing and away from the pneumatic system. A failure of this one gasket on the Клапан FAW J6P would cause both an air leak (failed shifting) and an oil leak.

Основной 2: The “Neutral Safety” Логика (The Interlock Switch)

This group contains the critical safety “interlock” для Клапан FAW J6P система. Its logic is to *prevent* a Hi/Lo range shift from occurring *unless* the main gearbox is in neutral, thereby protecting the range synchronizers from catastrophic damage.

1. Компонент: ‘Neutral gear switch – follower valve assy’ (1702337-A7G)
Этот (Комп 6) is the ‘Neutral gear switch’. Это “мозг” принадлежащий Клапан FAW J6P‘s safety circuit. It is a small plunger-style switch (either electric or pneumatic) that threads into the gearbox housing.

The Interlock Logic это его функция. The ‘Sleeve’ (Комп 4) and ‘Spring’ (Комп 5) form the plunger assembly. This plunger physically rides against the shift rails inside the main gearbox.

When the main gearbox is “in gear,” the shift rails are not in their “neutral” позиция, and the switch (Комп 6) is *open*. If the driver tries to range-shift, this switch *blocks* the pilot signal, и Клапан FAW J6P (Комп 1) will *not* activate.

When the driver moves the gear lever to “neutral,” the shift rail aligns, pushing the ‘Sleeve’ (Комп 4) and depressing the ‘Neutral gear switch’ (Комп 6). This *closes* the circuit, giving “permission” к Клапан FAW J6P. Сейчас, when the driver selects Hi or Lo, the pilot signal can pass through this switch, activate the ‘Follower valve’, and complete the shift.

2. Компонент: ‘O-ring’ (1702332-A7G)
Этот (Комп 3) is the static seal for the ‘Neutral gear switch’ (Комп 6). It’s a simple O-ring that seals the threads of the switch assembly, preventing gear oil from leaking out of the gearbox housing.

Основной 3: The “Распределение воздуха” Логика (Фильтр, Шланги, & Зажимы)

This group contains all the components responsible for the “сантехника” принадлежащий Клапан FAW J6P система. Its logic is to “condition” the compressed air and transport it to the correct components.

1. Компонент: ‘Air filter & connector assy’ (1702380-A7G)
Этот (Комп 11) is the ‘Air filter and connector’. Это “легкое” принадлежащий Клапан FAW J6P система, and it is a critical, serviceable item. It is mounted by ‘Hex flange bolts’ (Комп 12).

The Логика защиты is its job. The truck’s main air tanks (which supply the Клапан FAW J6P) are full of contaminants: вода (condensation), масло (from the air compressor), and rust particles. This ‘Air filter’ (Комп 11) contains a fine filter element that “cleans” this dirty air *before* it enters the precision-machined ‘Follower valve’ (Комп 1) and ‘Neutral gear switch’ (Комп 6).

Without this filter, the delicate O-rings and spools inside the Клапан FAW J6P would quickly become gummed up with oily sludge or scored by rust particles, leading to stuck valves and failed shifts.

2. The “Шланг” Группа (Комп 9, 10)
В эту группу входят: ‘Inlet hose – high gear’ (Комп 9) and ‘Inlet hose – low gear’ (Комп 10).

The Distribution Logic это их функция. These are the two high-pressure pneumatic hoses that run from the “выход” ports of the ‘Follower valve’ (Комп 1) к “вход” ports on the ‘Auxiliary Gearbox Range Cylinder’. One hose (Комп 9) carries the “Engage High Range” воздух. Другой (Комп 10) carries the “Engage Low Range” воздух.

3. Компонент: ‘Inlet hose control valve’ (1702341-A7G)
Этот (Комп 8) is another valve in the Клапан FAW J6P система. Given its name, it’s likely a one-way “check valve” or a “pressure protection valve.”

Его Control Logic is to “gate” the flow of air. It might be a quick-exhaust valve to make the shift faster, or a one-way check valve to ensure that pressure from the cylinder doesn’t “back-feed” into the Клапан FAW J6P. It’s a key “logic gate” in the pneumatic circuit.

4. Компонент: ‘Hose clamp’ (1702391-A7G)
Этот (Комп 13) is a simple “P-clamp” or ‘Hose clamp’. Его Anti-Chafing Logic is critical for reliability. This clamp secures the air hoses (Комп 9, 10) to the chassis or gearbox housing, preventing them from vibrating, rubbing against a spinning driveshaft, or melting on a hot exhaust component. This simple clamp prevents a catastrophic air leak.
