This is the definitive guide to the FAW J6P Zhongqiao (Eixo Médio) para o FAW Jiefang CA3250P66K2L1T1E 6×4 caminhão despejando. This complete deconstruction analyzes 105 peças reparáveis, providing a full service-level overview of this critical through-axle.

O FAW J6P Zhongqiao (Parte não. 2500010AA6E) is the engineering core of the 6×4 tandem-axle system. It is not a simple axle; it is the ‘through-axle’ or ‘forward-axle’ of the pair. Its primary role is twofold: primeiro, to receive power from the transmission and perform a main gear reduction (i=1.333), and second, to house the inter-axle differential, which splits power between the middle axle itself and the rearmost axle. This guide will explore the main reducer, the power divider, the wheel differential, and the dual-lock systems that make the FAW J6P Zhongqiao a robust, essential solution for heavy-haul applications.

Essencial 1: O “Entrada & Reducer” Lógica (The Pinion Assembly)

This assembly receives power from the main driveshaft and performs the first stage of gear reduction (i=1.333) para todo o FAW J6P Zhongqiao. The precision of this setup dictates the axle’s lifespan.

1. Componente: Consequência & Support Group (32315, 32314, 2502121-A0E)
The ‘Driven pinion’ (Comp. 9, 2502036AA6E) is the main input gear. It is rigidly supported by a set of heavy-duty tapered roller bearings, including ‘32315’ (Comp. 10) and ‘32314’ (Comp. 17), which sit in the ‘Outer race’ (Comp. 11). Esse Lógica de rolo cônico allows the pinion to handle immense radial (sideways) e axial (impulso) forces generated by the helical-cut gears.

2. Componente: ‘Adjustment shim-driven pinion’ (2402097~98-A0E) – Qty As Req.
Esse (Comp. 8) is a set of precision shims, provided in thicknesses like 0.5mm, 0.15milímetros, and 0.10mm. O Pinion Pre-load Logic is a high-precision assembly task. These shims are used to set the precise rotating torque (pré-carregamento) on the pinion bearings (Comp. 10 & 17). This adjustment is critical to the service life of the FAW J6P Zhongqiao.

3. Componente: Lubrificação & Sealing Group (2509015-A0E, 2502055-A0E)
This group includes the ‘Filter-oil house assy’ (Comp. 13), an internal filter screen that protects the gears and bearings from debris. It also includes the ‘Oil seal-driven pinion’ (Comp. 65), ‘Dust cap’ (Comp. 66), and ‘Flange-main reducer’ (Comp. 68). This system keeps the gear oil clean, prevents leaks, and protects the input of the FAW J6P Zhongqiao.

Essencial 2: O “Diferencial entre eixos” Lógica (Power Divider)

This is the ‘brain’ do FAW J6P Zhongqiao. It is a differential *within* the axle that splits torque not between the wheels, but between the middle axle and the rear axle (the ‘through-axle’ função).

1. Componente: ‘Inter-axle differential assy’ (2502105-A0E) – Quantidade 1
Esse (Comp. 45) is the complete serviceable unit. It is built into the ‘Front case-inter-axle diff’ (Comp. 46, 2507057-A0E) and ‘Rear case’ (Comp. 50, 2507058-A0E), which are bolted together with 12 ‘Shim’ parafusos (Comp. 51). This entire unit manages the front-to-rear power split.

2. Componente: ‘Cross-inter-axle diff’ (2507081-A0E) & ‘Planetary gear’ (2507076-A0E)
Esse (Comp. 47 & 49) é o Planetary Logic of the power divider. The ‘Cross’ (aranha) holds four ‘Planetary gears’, which are supported by ‘Shims’ (Comp. 48). These gears are what allow the middle and rear axles to rotate at different speeds when cornering, preventing drivetrain binding. This is essential for the on-road handling of the FAW J6P Zhongqiao.

3. Componente: ‘Driven pinion’ (2502108-A6E) & ‘Rear half shaft gear assy’ (2507065-A0E)
Esse (Comp. 18 & 52) shows the power flow. The ‘Driven pinion’ (Comp. 18) is the input gear for the inter-axle differential. The ‘Rear half shaft gear assy’ (Comp. 52) is the output gear that sends power to this axle’s *own* wheel differential. The other output (Comp. 76) sends power to the rear-most axle, completando o FAW J6P Zhongqiao through-axle design.

Essencial 3: O “Bloqueio duplo” Lógica (Controle Pneumático)

O FAW J6P Zhongqiao features a sophisticated dual-locking system. It has one lock for the inter-axle differential (power divider) and another for its own wheel-to-wheel differential.

1. Componente: Pneumatic Activation Group (Quantidade 2 of each)
The BOM shows ‘Qty 2’ for all pneumatic parts (Comp. 30-39). This includes the ‘Switch assy-diff lock indicator’ (Comp. 30), ‘Air cylinder’ (Comp. 37, 2406011-A0E), ‘Piston’ (Comp. 36, 2406013-A0E), and ‘O type ring’ (Comp. 35, 2406014-A0E). This is because one set controls the inter-axle lock and the second set controls the wheel-axle lock on this FAW J6P Zhongqiao.

2. Componente: Inter-Axle Lock Mechanism (Comp. 40, 42)
The first air actuator (Comp. 37) moves the ‘Fork-inter-axle diff lock’ (Comp. 42, 2508024-A0E), which slides the ‘Sliding sleeve’ (Comp. 40, 2508032-A0E) to lock the power divider. This forces a 50/50 power split between the middle and rear axles for extreme traction.

3. Componente: Wheel-Axle Lock Mechanism (Comp. 78, 80)
The second air actuator (the other Comp 37) moves the ‘Fork-wheel diff lock’ (Comp. 78, 2406024-A0E), which slides its own ‘Sliding sleeve’ (Comp. 80, 2406032-A0E). This locks the wheel differential (Comp A), forcing both wheels on the FAW J6P Zhongqiao to spin at the same speed.

Essencial 4: O “Wheel Differential” Lógica (Torque to Wheels)

Separate from the power divider, o FAW J6P Zhongqiao contains a complete, conventional differential for splitting torque between its own left and right wheels.

1. Componente: ‘Differential assy’ (2403015AA0E) – Quantidade 1
Esse (Comp A) is the complete wheel differential carrier. It is bolted to the ‘Driven pinion’ (Comp. 93, 2403037BA0E), which is the main ring gear for the wheel differential. É garantido por 16 ‘Bolts’ (Comp. 85, 2402063AA0E).

2. Componente: Planetary & Spider Group (Comp. 89, 90, 91, 92)
Esse Wheel Planetary Logic consists of the ‘Cross’ (Comp. 92, 2403061-A0E) which holds four ‘Planetary gears’ (Comp. 91, 2403056-A0E). These gears mesh with the two ‘Half shaft gears’ (Comp. 89, 2403051-A0E), allowing the ‘Left half shaft’ (Comp. 101) and ‘Right half shaft’ (Comp. 102) to rotate at different speeds.

3. Componente: Carrier Bearing & Adjustment Group (Comp. 83, 84)
The entire differential assembly (Comp A) is supported in the reducer housing (Comp. 6) by two massive ‘Tapered roller bearings’ (Comp. 84, 32216/YA6E). O Backlash Logic is set here. Technicians use the ‘Adjustment shim-differential bearing’ (Comp. 83, 2403071-A0E) to move the carrier left or right, setting the precise tooth contact pattern (backlash) between the pinion and ring gear. Esta é uma última, critical adjustment for the FAW J6P Zhongqiao.
