Ensemble logique FAW pour engrenages cylindriques actifs, Logement, Différentiel d'arbre et blocage de différentiel: Une analyse critique de 34 Composants

Bienvenue dans cette analyse critique de Ensemble logique FAW pour engrenages cylindriques actifs, Logement, Shaft Differential And Differential Lock Logic Assembly (Partie no. 2502010QA6T). C'est le complet “avant” ou “centre” drive axle differential carrier for the FAW Jiefang CA4251P66K24T1A3E5 6×4 tracteur semi-remorque diesel.

Le Ensemble logique FAW pour engrenages cylindriques actifs, Logement, Shaft Differential And Differential Lock Logic Assembly est le “cerveau” of the 6×4 drive system. C'est “logique” est double: d'abord, the ‘Inter-Shaft Differential’ (轴间差速器) splits power between the front and rear drive axles. Deuxième, 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. Nous déconstruirons l'ensemble Ensemble logique FAW pour engrenages cylindriques actifs, Logement, Shaft Differential And Differential Lock Logic Assembly dans son 34 composants réparables, including the main ‘Housing’, the ‘Active Cylindrical Gears’ (pinion and side gears), and the complete ‘Differential Lock Logic Assembly’.

Le “Logement” et “Engrenage conique d'entraînement” (Pignon)

Le Ensemble logique FAW pour engrenages cylindriques actifs, Logement, Shaft Differential And Differential Lock Logic Assembly est un complet “transporteur” ou “citrouille” unité. The ‘Housing’ (2502015-A6T / 2502018-A6T from the sub-list) c'est le massif, ribbed cast-iron foundation that holds all components in perfect, micromillimeter alignment.

The ‘Drive Bevel Gear’ component is the ‘Pinion shaft assembly’ (2502065-A6T). C'est le “saisir” arbre, which receives power from the main driveshaft. It is supported by two massive ‘Tapered roller bearing assembly’ unités (2402060-A8T-C00 et 2402050-A8T-C00). Ces roulements sont essentiels, as they must handle both the extreme radial load and the axial (poussée) 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. Le roulement d’arbre écrou-pignon’ (2402069-A0E) is the critical fastener that sets the “précharger” sur ces roulements. This preload is a precise “presser” set by the technician using the “au besoin” (Sur demande) ‘Adjustment gaskets’ (2402097-A6T, 2402098-A6T, 2402099-A6T). An incorrect preload on the Ensemble logique FAW pour engrenages cylindriques actifs, Logement, Shaft Differential And Differential Lock Logic Assembly will lead to rapid bearing failure.

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

This component is often mistaken, mais le “Shaft Differential” (轴间差速器) dans le Ensemble logique FAW pour engrenages cylindriques actifs, Logement, 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 unités:** Ce sont les “engrenages d'araignée.”
• **’Inter-axle differential cross’ (2507081-A6T):** Le “croix” qui tient les engrenages de l'araignée.
• **’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 “logique” allows the ‘Front side gear’ and ‘Rear side gear’ to spin at different speeds, empêcher “driveline bind-up” and saving the axles from immense stress. Il s’agit d’une fonction essentielle du Ensemble logique FAW pour engrenages cylindriques actifs, Logement, Shaft Differential And Differential Lock Logic Assembly.

Le “Ensemble logique de verrouillage du différentiel”

Le “Ensemble logique de verrouillage du différentiel” is the system that *overrides* the inter-axle differential. In low-traction (boue, neige, ou de la glace), allowing the front and rear axles to spin at different speeds is a weakness. The driver needs to “verrouillage” them together. Ce Ensemble logique FAW pour engrenages cylindriques actifs, Logement, Shaft Differential And Differential Lock Logic Assembly uses a pneumatic (à propulsion pneumatique) système.

Lorsque le conducteur retourne le “Inter-Axle Lock” changer, 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 “dents de chien,” physically locking the ‘Front side gear’ and ‘Rear side gear’ together. This forces both axles to spin at the same speed, fournissant un 50/50 torque split and maximum traction.

Le « Ressort de retour »’ (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 “logique” is a critical feature of the Ensemble logique FAW pour engrenages cylindriques actifs, Logement, Shaft Differential And Differential Lock Logic Assembly.

Le “Active Cylindrical Gears” et roulements

Le “Active Cylindrical Gears” de la Ensemble logique FAW pour engrenages cylindriques actifs, Logement, 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’ est le 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’ (Hache 80105).

This entire rotating assembly is supported by a series of ‘Cylindrical roller bearing assembly’ (2402075-A6T-C00) et « Ensemble de roulements à rouleaux coniques’ (2502050-A6T-C00) unités. The ‘Adjustment gasket-reducer bearing’ (2403074-A9T, 2403072-A6T, 2403073-A6T) shims are used to precisely set the preload on these critical bearings.

Ce Ensemble logique FAW pour engrenages cylindriques actifs, Logement, Shaft Differential And Differential Lock Logic Assembly est un complexe, “gear-within-a-gear” système. The pinion shaft spins, the inter-axle differential spins inside it, et le “through-shaft” passes through the center of it all.
