Eixo central direito FAW J6P: Desconstruindo 15 Peças críticas para divisão de torque perfeita

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

O Eixo central direito FAW J6P works in perfect harmony with its “Esquerda” counterpart to handle the immense power from the engine. Esse “twin-countershaft” 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.

Essencial 1: O “Haste & Keyway” Lógica (The Core Spine)

This group represents the foundation of the Eixo central direito 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. Componente: ‘Centre shaft’ (1701211-A7G)
Esse (Comp. 3) is the ‘Centre shaft’ em si, the spine of the assembly. Como o Eixo central direito FAW J6P, this component is identical to its left-side counterpart. É um único, eixo para serviço pesado, precision-machined from forged steel to be incredibly rigid and resistant to the torsional (twisting) forces of a high-torque diesel engine.

O Torque Splitting Logic is its core purpose. O Eixo central direito 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 “dirigido” gears on the mainshaft. This load-sharing is what makes the gearbox so robust.

2. O “Key” Grupo (Comp. 4, 5, 6)
Este grupo inclui: ‘Woodruff key’ (Comp. 4), 'Pino cilíndrico de mola’ (Comp. 5), and ‘Flat key’ (Comp. 6). These are all “locating keys” used to fix the gears to the Eixo central direito FAW J6P.

O Lógica de bloqueio é a função deles. The drive gears (like Comp 7, 8, 9) are not “free-spinning”; they must be rigidly locked to the Eixo central direito 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) é um simples, strong key for a straight slot. A ‘Spring pin’ (Comp. 5) is a vibration-proof pin, likely used to secure a gear collar.

Essencial 2: O “Main Drive Gear” Lógica (The Gear Set)

This is the primary “trabalhando” parte do Eixo central direito FAW J6P. These are the fixed gears that provide the “drive” torque to the mainshaft’s “dirigido” engrenagens.

1. O “Main Gears” (Comp. 7, 8, 9)
Este grupo inclui: ‘Segunda marcha – centre shaft’ (Comp. 7), ‘Terceira marcha – centre shaft’ (Comp. 8), e ‘Quarta marcha – centre shaft’ (Comp. 9). These gears are the drive-side of the main gear ratios.

O Constant Mesh Logic é a chave. Unlike the mainshaft gears (which spin freely), all gears on the Eixo central direito FAW J6P are *fixed* to the shaft (Por exemplo, 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 Eixo central direito FAW J6P, all these gears (2nd, 3terceiro, 4th) are spinning at the same RPM. The driver selects a gear by locking the corresponding “dirigido” engrenagem (on the mainshaft) to the mainshaft, which completes the power path for that specific ratio.

2. Componente: ‘Reduction gear – centre shaft’ (1701217-A7G)
Esse (Comp. 11) is the ‘Reduction gear’. This is likely the main “entrada” gear of the Eixo central direito FAW J6P, which meshes with the ‘First Axis’ (eixo de entrada) engrenagem.

Isso é Reduction Logic 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 Eixo central direito FAW J6P.

Essencial 3: O “Power Take-Off” Lógica (The PTO Gear)

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

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

O Hydraulic Logic is its application. This gear (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 Eixo central direito FAW J6P é crítico. 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 Eixo central direito FAW J6P projeto.

Essencial 4: O “Consequência & Retention” Lógica (The Mounts)

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

1. O “Consequência” Grupo (Comp. 2, 13)
Isso inclui: ‘Cylindrical roller bearing’ (Comp. 2) and ‘Cylindrical roller bearing with stop ring’ (Comp. 13). These are the main bearings for the Eixo central direito FAW J6P, supporting it at the front and rear of the gearbox case.

O 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 (o “pushing” force between gears) inside a heavy-duty gearbox. The ‘stop ring’ on Comp 13 is a snap ring on the *outer* race, qual “locates” the bearing in the housing bore.

2. O “Retention” Grupo (Comp. 1, 12, 14, 15)
Este grupo inclui: ‘Snap ring – centre shaft rear bearing’ (Comp. 1), ‘Snap ring – reduction gear’ (Comp. 12), ‘Baffle plate – centre shaft front bearing’ (Comp. 14), and ‘Hexagon head bolt with guide neck’ (Comp. 15).

O Axial Control Logic é a função deles. The ‘Snap rings’ (Comp. 1, 12) fit into grooves on the Eixo central direito FAW J6P itself to lock bearings or gears (like the ‘Reduction gear’, Comp. 11) no lugar, preventing any “axial” (in-and-out) movement.

O Baffle Plate Logic (Comp. 14) é crítico. This plate, held by the ‘Hexagon head bolt’ (Comp. 15), acts as a “retainer” 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 “respingo” from reaching the front seal. This entire group ensures the Eixo central direito FAW J6P stays perfectly positioned.
