Шланг FAW J6P: Деконструкция 13 Важные детали для безупречного пневматического управления

Welcome to this expert deconstruction of the Шланг FAW J6P, Клапан, and Connector assembly, the complete pneumatic “сантехника” circuit for the CA10TA160M 10-speed transmission. This system is a core part of the FAW Jiefang CA3250P66K2L1T1E 6×4 самосвал. This guide deconstructs all 13 компоненты, focusing on the Шланг FAW J6P lines.

The Шланг FAW J6P assembly is the “circulatory system” for the Hi/Lo range shifter. Its logic is to safely transport high-pressure compressed air from the control valves to the range cylinder, ensuring fast, reliable shifts. The integrity of this Шланг FAW J6P system is critical for protecting the gearbox and ensuring driver control.

Основной 1: The “Pneumatic Transport” Логика (The FAW J6P Hose Set)

This group represents the core “сантехника” of the entire range-shift system. Its logic is to be the flexible, durable conduit that moves high-pressure air from the “мозг” (клапаны) к “мышца” (the range cylinder). This is the primary role of the Шланг FAW J6P компоненты.

1. Компонент: ‘Inlet hose – high gear’ (1702343-A7G)
Этот (Комп 9) is the dedicated “High Range” air line. Этот Шланг FAW J6P connects one output port of the ‘Follower valve’ (Комп 1) directly to the “engage high” port on the ‘Auxiliary Gearbox Range Cylinder’.

The Durability Logic is its key feature. This is not a simple rubber tube. It is a multi-layer, reinforced pneumatic hose designed to withstand constant vibration, high engine-bay temperatures, and repeated pressure cycles of 120+ пси. It must also be resistant to oil and diesel-fuel mist. A failure in this specific Шланг FAW J6P means no high range.

2. Компонент: ‘Inlet hose – low gear’ (1702342-A7G)
Этот (Комп 10) is the second critical “Low Range” air line. Этот Шланг FAW J6P connects the *other* output port of the ‘Follower valve’ (Комп 1) к “engage low” port on the dual-action range cylinder.

The Dual-Path Logic имеет важное значение. The range cylinder is “powered” in both directions (no spring return). This requires two separate, dedicated Шланг FAW J6P lines: one to push the piston (НАПРИМЕР., engage High) and one to pull it (engage Low). A failure in this hose (Комп 10) would mean the driver could shift *into* high range, but could not shift back *out* into low range.

3. Компонент: ‘Hose clamp’ (1702391-A7G)
Этот (Комп 13) is a simple “P-clamp” or ‘Hose clamp’, but it is a critical safety component for the Шланг FAW J6P система.

The Anti-Chafing Logic это его единственная цель. This clamp is used to securely bolt the Шланг FAW J6P lines (Комп 9 и 10) to a fixed point on the gearbox housing or chassis. This prevents the hoses from vibrating, rubbing against the spinning driveshaft, or resting on the hot exhaust system. This one, simple clamp prevents a “rub-through” hole that would cause a total failure of the range-shift system.

Основной 2: The “Air Conditioning” Логика (The Filter)

Before compressed air can be trusted to enter the precision-engineered Шланг FAW J6P and valve system, это должно быть “conditioned” (cleaned and dried). This is the job of the air filter assembly.

1. Компонент: ‘Air filter & connector assy’ (1702380-A7G)
Этот (Комп 11) это “легкое” of the entire pneumatic shift system. It is the first component in the circuit, receiving its air supply from the truck’s main tanks. It is mounted to the gearbox housing by two ‘Hexagon flange bolts’ (Комп 12).

The Логика защиты это его важнейшая функция. The compressed air in a truck’s main tanks is notoriously “dirty.” It contains water (from atmospheric condensation), atomized oil (from the air compressor’s crankcase), and small rust/scale particles.

This ‘Air filter’ (Комп 11) contains a fine filter element that “scrubs” this air, trapping the water, масло, и мусор. This clean, dry air is then fed to the ‘Follower valve’ (Комп 1) and the rest of the Шланг FAW J6P схема.

Without this filter, the delicate rubber O-rings and tight-tolerance spools inside the ‘Follower valve’ and ‘Neutral gear switch’ (Комп 6) would quickly become fouled with an oily sludge. This would cause the valves to stick, leading to slow, erratic, or completely failed range shifts. This filter protects every component in the Шланг FAW J6P система.

Основной 3: The “Pneumatic Control” Логика (The Valves)

This group contains the “мозги” принадлежащий Шланг FAW J6P система. These valves receive signals from the driver and the gearbox, and then “decide” when and where to send the compressed air.

1. Компонент: ‘Follower valve assy’ (1702320-A7G)
Этот (Комп 1) является основным “привод” клапан, also known as a slave valve. It is a high-volume air relay. Его “логика” is to receive a small, low-volume “pilot” сигнал (from the driver’s Hi/Lo switch) and use it to trigger a much larger internal valve.

This main valve then releases a high-volume blast of air into the correct Шланг FAW J6P (Комп 9 for Hi, Комп 10 for Lo) to power the range cylinder. This relay system ensures an “instant” сдвиг.

2. Компонент: ‘Neutral gear switch – follower valve assy’ (1702337-A7G)
Этот (Комп 6) is the critical “safety interlock” на весь Шланг FAW J6P система. It is a small plunger switch (with its ‘Sleeve’, Комп 4, and ‘Spring’, Комп 5) that reads the physical position of the main gearbox shift rails.

Его Interlock Logic это просто: it *blocks* the pilot signal to the ‘Follower valve’ (Комп 1) *unless* the main gearbox is in neutral. This prevents a driver from attempting a range-shift while “in gear,” an action that would destroy the range synchronizers. This valve is a critical “permission” switch for the Шланг FAW J6P схема.

3. Компонент: ‘Inlet hose control valve’ (1702341-A7G)
Этот (Комп 8) is another logic valve in the Шланг FAW J6P схема. It is likely a “one-way check valve” или “pressure protection valve.” Its logic is to “форма” the air pulse, possibly to act as a quick-exhaust to speed up shifts, or to prevent air from “back-feeding” from the cylinder to the main valve.

Основной 4: The “Уплотнение & Застежка” Логика (Аппаратное обеспечение)

This final group contains all the static seals and high-tensile hardware that physically mount the Шланг FAW J6P and valve components to the gearbox, ensuring a leak-proof and vibration-proof assembly.

1. The “Статическое уплотнение” Группа (Комп 2, 3)
В эту группу входят: «Прокладка – follower valve assy’ (Комп 2) and ‘O-ring’ (Комп 3). These are the two primary static seals for the Шланг FAW J6P система управления.

The ‘Gasket’ (Комп 2) provides the large “face seal” for the main ‘Follower valve’ (Комп 1), providing both an air and oil seal. The ‘O-ring’ (Комп 3) provides the “radial seal” for the ‘Neutral gear switch’ (Комп 6) as it threads into the gearbox housing.

2. The “Застежка” Группа (Комп 7, 12)
В эту группу входят: ‘Болт с шестигранной головкой’ (Комп 7, Кол-во 4) и «Болт с шестигранным фланцем’ (Комп 12, Кол-во 2).

The Flange Bolt Logic is a vibration-resistant design. Это не стандартные болты. They have a “фланец” (a built-in washer) that distributes clamping force over a wider area.

The four ‘Hexagon flange bolts’ (Комп 7) are used to mount the main ‘Follower valve’ (Комп 1), compressing the ‘Gasket’ (Комп 2). The two ‘Hexagon flange bolts’ (Комп 12) are used to mount the ‘Air filter’ (Комп 11). These fasteners are critical to securing the Шланг FAW J6P and valve system against constant engine vibration.
