FAW Logic Assembly For Active Cylindrical Gears, Habitação, Shaft Differential And Differential Lock: Uma análise crítica de 34 Componentes

Welcome to this critical analysis of the FAW Logic Assembly For Active Cylindrical Gears, Habitação, Shaft Differential And Differential Lock Logic Assembly (Parte não. 2502010QA6T). Este é o completo “forward” ou “centre” drive axle differential carrier for the FAW Jiefang CA4251P66K24T1A3E5 6×4 trator semirreboque diesel.

O FAW Logic Assembly For Active Cylindrical Gears, Habitação, Shaft Differential And Differential Lock Logic Assembly é o “cérebro” of the 6×4 drive system. Isso é “lógica” é duplo: primeiro, the ‘Inter-Shaft Differential’ (轴间差速器) splits power between the front and rear drive axles. Segundo, the ‘Differential Lock’ provides a pneumatic, driver-controlled mechanism to *override* this logic for maximum traction.

This in-depth guide is essential for driveline technicians. Vamos desconstruir todo FAW Logic Assembly For Active Cylindrical Gears, Habitação, Shaft Differential And Differential Lock Logic Assembly em seu 34 componentes reparáveis, including the main ‘Housing’, the ‘Active Cylindrical Gears’ (pinion and side gears), and the complete ‘Differential Lock Logic Assembly’.

O “Habitação” e “Dirija engrenagem chanfrada” (Pinhão)

O FAW Logic Assembly For Active Cylindrical Gears, Habitação, Shaft Differential And Differential Lock Logic Assembly is a complete “operadora” ou “pumpkin” unidade. The ‘Housing’ (2502015-A6T / 2502018-A6T from the sub-list) é o enorme, ribbed cast-iron foundation that holds all components in perfect, micromillimeter alignment.

The ‘Drive Bevel Gear’ component is the ‘Pinion shaft assembly’ (2502065-A6T). Este é o “entrada” shaft, which receives power from the main driveshaft. It is supported by two massive ‘Tapered roller bearing assembly’ unidades (2402060-A8T-C00 and 2402050-A8T-C00). Esses rolamentos são críticos, as they must handle both the extreme radial load and the axial (thrust) load from the helical gear mesh.

This pinion shaft is sealed by the ‘Centre axle input shaft oil seal assy’ (2502055-A6T-C00), which prevents gear oil from leaking out the front. The ‘Nut-pinion shaft bearing’ (2402069-A0E) is the critical fastener that sets the “pré-carregamento” on these bearings. This preload is a precise “squeeze” set by the technician using the “as needed” (Sob demanda) ‘Adjustment gaskets’ (2402097-A6T, 2402098-A6T, 2402099-A6T). An incorrect preload on the FAW Logic Assembly For Active Cylindrical Gears, Habitação, Shaft Differential And Differential Lock Logic Assembly will lead to rapid bearing failure.

O “Shaft Differential” (Inter-Axle Differential Logic)

This component is often mistaken, mas o “Shaft Differential” (轴间差速器) no FAW Logic Assembly For Active Cylindrical Gears, Habitação, Shaft Differential And Differential Lock Logic Assembly is the **Inter-Axle Differential**. Its logic is to split power *between* the front-drive-axle and the rear-drive-axle.

This differential is a planetary gearset housed inside the ‘Inter-axle differential housing’ (2502105-A6T). It consists of:

• **’Planetary gear-inter-axle differential’ (2507076-A0E) – 4 unidades:** Estes são os “engrenagens de aranha.”
• **’Inter-axle differential cross’ (2507081-A6T):** O “cross” que segura as engrenagens da aranha.
• **’Front side gear-inter-axle differential’ (2507057-A6T):** This gear sends power to the centre axle’s own ring gear.
• **’Rear side gear-inter-axle differential’ (2507066-A6T):** This gear sends power to the “through-shaft” (2502136-A6T), which leads to the rear-most axle.

When the truck turns, the front and rear axles travel different distances. This differential “lógica” allows the ‘Front side gear’ and ‘Rear side gear’ to spin at different speeds, prevenindo “driveline bind-up” and saving the axles from immense stress. This is a core function of the FAW Logic Assembly For Active Cylindrical Gears, Habitação, Shaft Differential And Differential Lock Logic Assembly.

O “Differential Lock Logic Assembly”

O “Differential Lock Logic Assembly” is the system that *overrides* the inter-axle differential. In low-traction (lama, neve, or ice), allowing the front and rear axles to spin at different speeds is a weakness. The driver needs to “trancar” eles juntos. Esse FAW Logic Assembly For Active Cylindrical Gears, Habitação, Shaft Differential And Differential Lock Logic Assembly uses a pneumatic (air-powered) sistema.

When the driver flips the “Inter-Axle Lock” trocar, high-pressure air is sent to the ‘Air cylinder-inter wheel diff lock’ (2406011-A0E) and ‘Air cylinder’ (2406016-A6T). This air pushes the ‘Piston-inter wheel differential lock’ (2406013-A0E).

The piston moves the ‘Fork assembly’ (2406025-A3C), which then pushes the ‘Sliding sleeve-inter-axle diff lock’ (2508032-A0E). This sleeve slides over and engages a set of “dentes de cachorro,” physically locking the ‘Front side gear’ and ‘Rear side gear’ together. This forces both axles to spin at the same speed, fornecendo a 50/50 torque split and maximum traction.

A ‘primavera do retorno’ (2406028-A0E) disengages the lock when the air pressure is released. The ‘Inter-axle differential lock switch assembly’ (3834050-A0E) is the sensor that confirms the lock is engaged, turning on the dashboard indicator light. This pneumatic-mechanical “lógica” is a critical feature of the FAW Logic Assembly For Active Cylindrical Gears, Habitação, Shaft Differential And Differential Lock Logic Assembly.

O “Active Cylindrical Gears” e rolamentos

O “Active Cylindrical Gears” do FAW Logic Assembly For Active Cylindrical Gears, Habitação, Shaft Differential And Differential Lock Logic Assembly keyword refers to the ‘Active cylindrical gear’ (2502136-A6T) and the planetary/side gear set. The ‘Active cylindrical gear’ é o principal “through-shaft” that is locked to the ‘Rear side gear’ (2507066-A6T). It passes *through* the center of the ‘Pinion shaft’ (2502065-A6T), supported by the ‘Thrust needle bearing and holder assembly’ (AXK 80105).

This entire rotating assembly is supported by a series of ‘Cylindrical roller bearing assembly’ (2402075-A6T-C00) e 'Conjunto de rolamento de rolos cônicos’ (2502050-A6T-C00) unidades. The ‘Adjustment gasket-reducer bearing’ (2403074-A9T, 2403072-A6T, 2403073-A6T) shims are used to precisely set the preload on these critical bearings.

Esse FAW Logic Assembly For Active Cylindrical Gears, Habitação, Shaft Differential And Differential Lock Logic Assembly é um complexo, “gear-within-a-gear” sistema. The pinion shaft spins, the inter-axle differential spins inside it, e o “through-shaft” passes through the center of it all.
