Boîtier de boîte de vitesses russe FAW: Ingénierie 35 Composants stratégiques pour la réduction de l'essieu central

Le Boîtier de boîte de vitesses russe FAW assembly is the foundational bedrock for the middle axle reducer of the CA3250P66K24L1TE5Z dump truck. Serving as the primary containment vessel, it houses the critical reduction gears and the inter-axle differential lock mechanism. Conçu spécifiquement pour l'Arctique sibérien, this housing ensures precise gear alignment and robust protection against impact and thermal shock in temperatures plunging to -40°C.

FAW Russian Gearbox Housing Logic Assembly

Logique du logement: The Iron Fortress

The structural backbone of this assembly is the Boîtier de réducteur – Essieu central (Partie no. 2502018-A6E). Au sein du Boîtier de boîte de vitesses russe FAW logique, this casting is manufactured from high-grade nodular iron. This material choice is critical for the Russian market to prevent brittle fracture during cold starts. The housing rigidly supports the Siège de roulement (Partie no. 2502049-A6E), which cradles the input shaft. La précision géométrique du Boîtier de boîte de vitesses russe FAW determines the mesh quality of the gears. If the housing flexes under load, tooth contact patterns shift, leading to noise and premature failure. Donc, the internal ribbing is optimized to handle the separating forces generated by the high-torque helical gears used in this heavy-duty application.

Le Boîtier de boîte de vitesses russe FAW also integrates the mounting points for the differential bearing caps. Le Capuchon – Roulement de différentiel (Partie no. 2402019-A0E) et Capuchon – Roulement de différentiel (Partie no. 2502019-A0E) are machined together with the main housing to ensure perfect concentricity. Ce “matched set” manufacturing process eliminates misalignment that could cause bearing binding. The housing is designed with specific oil channels to direct lubricant to the pinion bearings, ensuring they remain cool even when the truck is hauling maximum payload at highway speeds. The exterior is coated with a corrosion-resistant finish to withstand the harsh saline slush found on winter roads in Russia.

Gear Train: Bevel and Cylindrical Integration

The power transmission within the Boîtier de boîte de vitesses russe FAW relies on the interaction between the Engrenage conique d'entraînement (Partie no. 2502036BA6E) et le Engrenage cylindrique entraîné (Partie no. 2502108-A6E). This configuration is specific to the middle axle, allowing power to be split between the middle wheels and the rear axle. The metallurgy of these gears is formulated to resist pitting fatigue. À l'intérieur du Boîtier de boîte de vitesses russe FAW, the gears run in a bath of specialized gear oil. To prevent aeration and ensure a continuous lubricant film on the gear teeth, l'ensemble comprend le Bouclier d'huile – Siège de roulement d'engrenage conique d'entraînement (Partie no. 2402048-A0E). This shield manages oil flow, preventing churning losses while ensuring that the high-speed pinion bearings receive adequate lubrication.

The input to the system is secured by the Noix – Drive Bevel Gear Flange (Partie no. 2402069-A0E), which clamps the Drive Bevel Gear Flange Assembly (Partie no. 2402065-A0E) to the pinion shaft. This connection must withstand the full torque of the engine. The gears within the Boîtier de boîte de vitesses russe FAW are precision-ground to minimize noise and vibration. In the context of the CA3250P66K24L1TE5Z, the gearing is designed for low-speed, high-torque applications typical of mining and construction. The robust nature of the gear teeth ensures they can withstand the shock loads experienced when the truck’s wheels encounter sudden resistance or slip on uneven terrain.

Logique de rotation: Bearings and Preload

Supporting the rotating assemblies within the Boîtier de boîte de vitesses russe FAW are heavy-duty Roulement à rouleaux coniques unités (Partie no. 32314 et numéro de pièce. 32315). These bearings handle both radial and axial loads generated by the gear mesh. La longévité du Boîtier de boîte de vitesses russe FAW depends on precise bearing preload. This is achieved using Réglage de la cale – Siège de roulement d'engrenage conique d'entraînement (Numéros de pièces. 2502097-A6E, 2502098-A6E, 2502099-A6E). Technicians stack these shims to set the pinion depth and bearing tightness. Dans l'Arctique, thermal contraction of the iron housing can increase preload. Donc, the assembly specifications for the Boîtier de boîte de vitesses russe FAW are calibrated to accommodate wide temperature fluctuations, ensuring the bearings do not seize when the truck starts in -40°C weather.

The bearing arrangement includes the Entretoise – Roulement d'engrenage conique d'entraînement (Partie no. 2502088-A0E) et le Rondelle de réglage – Roulement d'engrenage conique d'entraînement (Partie no. 2402081-A0E). These components create a rigid spacing between the inner and outer bearings, maintaining the stiffness of the pinion shaft. Le Boîtier de boîte de vitesses russe FAW utilise également le Bague de réglage – Roulement différentiel (Partie no. 2403071-A0E) to set the backlash of the differential carrier bearings. This threaded adjustment allows for fine-tuning of the gear mesh without disassembly. Le Plaque de verrouillage – Bague de réglage (Partie no. 2403072-A0E) then secures this setting, preventing the ring from backing out under the intense vibration of off-road driving.

Antipatinage: The Pneumatic Lock System

A critical feature housed within the Boîtier de boîte de vitesses russe FAW is the inter-wheel differential lock. This pneumatic system ensures traction on icy roads. Il se compose du Cylindre pneumatique – Verrouillage du différentiel entre les roues (Partie no. 2406011-A0E), Piston – Verrouillage du différentiel entre les roues (Partie no. 2406013-A0E), et Fourche de changement de vitesse – Verrouillage du différentiel entre les roues (Partie no. 2406024-A0E). Lorsqu'il est activé, the fork pushes the Manchon d'engrenage mobile – Verrouillage du différentiel entre les roues (Partie no. 2406032-A0E) to engage the Manchon d'engrenage fixe – Verrouillage du différentiel entre les roues (Partie no. 2406033-A0E). Le Boîtier de boîte de vitesses russe FAW design ensures that these components are aligned perfectly to prevent binding.

The pneumatic system is sealed by the Joint torique – Piston de blocage de différentiel (Partie no. 2406014-55R.) et le Joint – Couvercle du cylindre pneumatique (Partie no. 2406017-A0E). Le “55R.” suffix on the O-ring indicates a special cold-resistant rubber compound that stays flexible at low temperatures, preventing air leaks in the Boîtier de boîte de vitesses russe FAW. The system is capped by the Couverture – Cylindre pneumatique (Partie no. 2406016-A0E) and secured with Boulon – Fastening Inter-wheel Diff Lock Air Cylinder Cover (Partie no. 2406018-A0E). Le Inter-wheel Diff Lock Switch Assembly (Partie no. 3834050-A0E) provides feedback to the driver, confirming that the axle is locked and ready for low-traction maneuvers.

Assembly Security: Boulons et bouchons

L'intégrité du Boîtier de boîte de vitesses russe FAW is maintained by high-tensile fasteners. The assembly uses multiple units of Boulon – Réducteur de fixation (Partie no. 2402016-1H) et Boulon – Réducteur de fixation (Partie no. 2402017-1H). These bolts clamp the bearing seats and covers to the main housing. Dans l’environnement à fortes vibrations d’un camion-benne, these bolts are installed with thread locker to prevent backing out. Le Broche de soutien – Boîtier de réducteur & Boîtier d'essieu (Partie no. 2402021-A0E) provides shear strength and alignment between the reduction unit and the main axle beam.

Fluid retention is managed by the Internal Hex Tapered Magnetic Plug (Partie no. T62106). This plug, installed in the Boîtier de boîte de vitesses russe FAW, sert un double objectif: it seals the drain port and captures ferrous debris from the oil. This magnetic filtration protects the gears and bearings from abrasive wear. The housing also features the Joint de coude terminal (Partie no. CQ63505) for air line connection. The mechanical security of the internal components is further reinforced by the Anneau élastique en fil de fer – Manchon de pignon fixe à verrouillage de différentiel (Partie no. 2406034-A0E), ensuring that the locking mechanism remains intact under the severe shock loads of engagement.
