Arbre central droit FAW J6P: Déconstruction 15 Pièces critiques pour une répartition parfaite du couple

Welcome to this specialized technical analysis of the Arbre central droit FAW J6P, a foundational component in the CA10TA160M gearbox for the FAW Jiefang CA3250P66K2L1T1E 6×4 tombereau. This guide provides a complete deconstruction of the 15 parts that make up the Arbre central droit FAW J6P, un critique “countershaft” in the transmission’s twin-shaft design.

Le Arbre central droit FAW J6P works in perfect harmony with its “Gauche” counterpart to handle the immense power from the engine. Ce “à double arbre intermédiaire” logic splits the torque, effectively halving the load on each gear tooth. This design is essential for the durability and reliability required in a heavy-duty dump truck application.

Cœur 1: Le “Arbre & Keyway” Logique (The Core Spine)

This group represents the foundation of the Arbre central droit FAW J6P. It includes the shaft itself and the various keys used to permanently lock the drive gears onto it, ensuring the entire assembly spins as one solid unit.

1. Composant: ‘Centre shaft’ (1701211-A7G)
Ce (Comp 3) is the ‘Centre shaft’ lui-même, the spine of the assembly. Comme le Arbre central droit FAW J6P, this component is identical to its left-side counterpart. C'est un seul, heavy-duty shaft, precision-machined from forged steel to be incredibly rigid and resistant to the torsional (twisting) forces of a high-torque diesel engine.

Le Torque Splitting Logic is its core purpose. Le Arbre central droit FAW J6P runs parallel to the mainshaft and the ‘Left Centre Shaft’. It receives approximately 50% of the power from the input shaft gear and is in constant, permanent mesh with the “conduit” gears on the mainshaft. This load-sharing is what makes the gearbox so robust.

2. Le “Clé” Groupe (Comp 4, 5, 6)
Ce groupe comprend: ‘Woodruff key’ (Comp 4), ‘Spring cylindrical pin’ (Comp 5), and ‘Flat key’ (Comp 6). These are all “locating keys” used to fix the gears to the Arbre central droit FAW J6P.

Le Logique de verrouillage est leur fonction. The drive gears (comme Comp 7, 8, 9) are not “free-spinning”; they must be rigidly locked to the Arbre central droit FAW J6P. A ‘Woodruff key’ (Comp 4) is a half-moon shaped key that sits in a crescent-shaped slot, locking a gear hub in place. A ‘Flat key’ (Comp 6) est un simple, strong key for a straight slot. A ‘Spring pin’ (Comp 5) is a vibration-proof pin, likely used to secure a gear collar.

Cœur 2: Le “Engrenage d'entraînement principal” Logique (The Gear Set)

C'est le primaire “fonctionnement” une partie du Arbre central droit FAW J6P. These are the fixed gears that provide the “conduire” torque to the mainshaft’s “conduit” engrenages.

1. Le “Main Gears” (Comp 7, 8, 9)
Ce groupe comprend: ‘Second gear – centre shaft’ (Comp 7), ‘Third gear – centre shaft’ (Comp 8), and ‘Fourth gear – centre shaft’ (Comp 9). These gears are the drive-side of the main gear ratios.

Le Logique de maillage constant est la clé. Unlike the mainshaft gears (which spin freely), all gears on the Arbre central droit FAW J6P are *fixed* to the shaft (Par exemple, by the keys in Core 1). They spin as one single, solid unit, perfectly synchronized with the ‘Left Centre Shaft’.

This means when the engine turns the Arbre central droit FAW J6P, all these gears (2nd, 3rd, 4ème) are spinning at the same RPM. The driver selects a gear by locking the corresponding “conduit” engrenage (on the mainshaft) to the mainshaft, which completes the power path for that specific ratio.

2. Composant: ‘Reduction gear – centre shaft’ (1701217-A7G)
Ce (Comp 11) is the ‘Reduction gear’. This is likely the main “saisir” gear of the Arbre central droit FAW J6P, which meshes with the ‘First Axis’ (arbre d'entrée) engrenage.

C'est Logique de réduction is to provide the first, main gear reduction in the entire gearbox. It multiplies the torque *before* it even gets to the 2nd/3rd/4th gears, providing the massive “grunt” ou “pulling power” needed for a dump truck. It is secured on the shaft by its own ‘Snap ring’ (Comp 12). This gear’s health is critical to the Arbre central droit FAW J6P.

Cœur 3: Le “Prise de force” Logique (The PTO Gear)

This component’s logic is to provide a “robinet” ou “take-off” point for the engine’s power, allowing it to run auxiliary equipment, which is essential for a dump truck.

1. Composant: ‘PTO gear – centre shaft’ (1701246-A7G)
Ce (Comp 10) is the ‘Power Take-Off Gear’. This gear is also fixed to the Arbre central droit FAW J6P and spins constantly with it (anytime the clutch is engaged).

Le Hydraulic Logic is its application. Cet équipement (Comp 10) is what meshes with the idler gear of the PTO unit (which is bolted to the side of the gearbox housing). When the driver engages the PTO, this gear transmits the engine’s power *out* of the gearbox to run the hydraulic pump for the dump body.

Its position on the Arbre central droit FAW J6P est critique. Because this shaft spins whenever the clutch is engaged (even when the main gearbox is in neutral), it allows the dump truck to be stationary but still use the engine’s power to run the hydraulic pump and raise the dump bed. This functionality is a hallmark of the Arbre central droit FAW J6P conception.

Cœur 4: Le “Palier & Rétention” Logique (The Mounts)

This final group is responsible for supporting the entire Arbre central droit FAW J6P assemblée, holding it in its precise location and allowing it to spin smoothly under immense radial and axial loads.

1. Le “Palier” Groupe (Comp 2, 13)
Cela comprend: ‘Cylindrical roller bearing’ (Comp 2) and ‘Cylindrical roller bearing with stop ring’ (Comp 13). These are the main bearings for the Arbre central droit FAW J6P, supporting it at the front and rear of the gearbox case.

Le Roller Bearing Logic is used for its superior strength. Unlike ball bearings, roller bearings have a larger contact patch, making them ideal for handling the extremely high *radial* loads (le “pousser” force between gears) inside a heavy-duty gearbox. The ‘stop ring’ sur Comp 13 is a snap ring on the *outer* race, lequel “locates” the bearing in the housing bore.

2. Le “Rétention” Groupe (Comp 1, 12, 14, 15)
Ce groupe comprend: 'Anneau à pression – centre shaft rear bearing’ (Comp 1), 'Anneau à pression – reduction gear’ (Comp 12), ‘Baffle plate – centre shaft front bearing’ (Comp 14), and ‘Hexagon head bolt with guide neck’ (Comp 15).

Le Axial Control Logic est leur fonction. The ‘Snap rings’ (Comp 1, 12) fit into grooves on the Arbre central droit FAW J6P itself to lock bearings or gears (like the ‘Reduction gear’, Comp 11) en place, preventing any “axial” (in-and-out) mouvement.

Le Baffle Plate Logic (Comp 14) est critique. This plate, held by the ‘Hexagon head bolt’ (Comp 15), agit comme un “retenue” for the front bearing (Comp 13). It also functions as an “oil slinger” ou “baffle,” directing lubricating oil into the bearing race while also preventing excessive “éclabousser” from reaching the front seal. This entire group ensures the Arbre central droit FAW J6P stays perfectly positioned.
