Tuyau FAW J6P: Déconstruction 13 Pièces critiques pour un contrôle pneumatique parfait

Bienvenue dans cette déconstruction experte du Tuyau FAW J6P, Soupape, et assemblage de connecteur, the complete pneumatic “plomberie” circuit for the CA10TA160M 10-speed transmission. Ce système est un élément essentiel du FAW Jiefang CA3250P66K2L1T1E 6×4 tombereau. Ce guide déconstruit tout 13 composants, focusing on the Tuyau FAW J6P lignes.

Le Tuyau FAW J6P l'assemblage est le “système circulatoire” 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. L'intégrité de ce Tuyau FAW J6P system is critical for protecting the gearbox and ensuring driver control.

Cœur 1: Le “Pneumatic Transport” Logique (The FAW J6P Hose Set)

Ce groupe représente le noyau “plomberie” of the entire range-shift system. Its logic is to be the flexible, durable conduit that moves high-pressure air from the “cerveau” (les vannes) au “muscle” (the range cylinder). This is the primary role of the Tuyau FAW J6P composants.

1. Composant: « Tuyau d'arrivée – vitesse élevée’ (1702343-A7G)
Ce (Comp 9) is the dedicated “Haut de gamme” ligne aérienne. Ce Tuyau FAW J6P connects one output port of the ‘Follower valve’ (Comp 1) directly to the “engage high” port on the ‘Auxiliary Gearbox Range Cylinder’.

Le Logique de durabilité is its key feature. This is not a simple rubber tube. C'est un multicouche, reinforced pneumatic hose designed to withstand constant vibration, high engine-bay temperatures, and repeated pressure cycles of 120+ psi. It must also be resistant to oil and diesel-fuel mist. A failure in this specific Tuyau FAW J6P means no high range.

2. Composant: « Tuyau d'arrivée – vitesse basse’ (1702342-A7G)
Ce (Comp 10) is the second critical “Gamme basse” ligne aérienne. Ce Tuyau FAW J6P connects the *other* output port of the ‘Follower valve’ (Comp 1) au “engage low” port on the dual-action range cylinder.

Le Dual-Path Logic est essentiel. The range cylinder is “alimenté” dans les deux sens (no spring return). This requires two separate, dedicated Tuyau FAW J6P lignes: one to push the piston (Par exemple, engage High) and one to pull it (engage Low). A failure in this hose (Comp 10) would mean the driver could shift *into* high range, but could not shift back *out* into low range.

3. Composant: « Collier de serrage’ (1702391-A7G)
Ce (Comp 13) est un simple “Pince en P” ou « Collier de serrage », but it is a critical safety component for the Tuyau FAW J6P système.

Le Logique anti-frottement est son seul but. This clamp is used to securely bolt the Tuyau FAW J6P lignes (Comp 9 et 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 “frotter” hole that would cause a total failure of the range-shift system.

Cœur 2: Le “Climatisation” Logique (The Filter)

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

1. Composant: 'Filtre à air & ensemble de connecteur’ (1702380-A7G)
Ce (Comp 11) est le “poumon” 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’ (Comp 12).

Le Logique de protection est sa fonction critique. 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.

Ce « Filtre à air’ (Comp 11) contient un élément filtrant fin qui “scrubs” this air, trapping the water, huile, et débris. This clean, dry air is then fed to the ‘Follower valve’ (Comp 1) and the rest of the Tuyau FAW J6P circuit.

Sans ce filtre, the delicate rubber O-rings and tight-tolerance spools inside the ‘Follower valve’ et « Commutateur de vitesse neutre’ (Comp 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 Tuyau FAW J6P système.

Cœur 3: Le “Commande pneumatique” Logique (The Valves)

This group contains the “cerveau” de la Tuyau FAW J6P système. These valves receive signals from the driver and the gearbox, and then “décider” when and where to send the compressed air.

1. Composant: « Ensemble de vanne suiveuse’ (1702320-A7G)
Ce (Comp 1) est le principal “actionneur” soupape, également connue sous le nom de vanne esclave. C'est un relais aérien à grand volume. C'est “logique” is to receive a small, low-volume “pilote” signal (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 Tuyau FAW J6P (Comp 9 for Hi, Comp 10 for Lo) to power the range cylinder. This relay system ensures an “instant” changement.

2. Composant: « Commutateur de vitesse neutre – ensemble de vanne suiveuse’ (1702337-A7G)
Ce (Comp 6) est la critique “safety interlock” pour l'ensemble Tuyau FAW J6P système. It is a small plunger switch (with its ‘Sleeve’, Comp 4, and ‘Spring’, Comp 5) that reads the physical position of the main gearbox shift rails.

C'est Logique de verrouillage c'est simple: it *blocks* the pilot signal to the ‘Follower valve’ (Comp 1) *unless* the main gearbox is in neutral. This prevents a driver from attempting a range-shift while “en prise,” an action that would destroy the range synchronizers. This valve is a critical “autorisation” switch for the Tuyau FAW J6P circuit.

3. Composant: « Valve de commande du tuyau d'arrivée’ (1702341-A7G)
Ce (Comp 8) is another logic valve in the Tuyau FAW J6P circuit. It is likely a “one-way check valve” ou “soupape de protection contre la pression.” Sa logique est de “forme” 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.

Cœur 4: Le “Scellage & Attache” Logique (Matériel)

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

1. Le “Static Seal” Groupe (Comp 2, 3)
Ce groupe comprend: 'Joint – ensemble de vanne suiveuse’ (Comp 2) and ‘O-ring’ (Comp 3). These are the two primary static seals for the Tuyau FAW J6P système de contrôle.

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

2. Le “Attache” Groupe (Comp 7, 12)
Ce groupe comprend: « Boulon à bride hexagonale’ (Comp 7, Quantité 4) and ‘Hexagon flange bolt’ (Comp 12, Quantité 2).

Le Flange Bolt Logic is a vibration-resistant design. Ce ne sont pas des boulons standards. They have a “bride” (a built-in washer) that distributes clamping force over a wider area.

The four ‘Hexagon flange bolts’ (Comp 7) are used to mount the main ‘Follower valve’ (Comp 1), comprimer le « joint »’ (Comp 2). The two ‘Hexagon flange bolts’ (Comp 12) are used to mount the ‘Air filter’ (Comp 11). These fasteners are critical to securing the Tuyau FAW J6P and valve system against constant engine vibration.
