Carcaça da caixa de engrenagens russa FAW: Engenharia 35 Componentes Estratégicos para Redução do Eixo Médio

O Carcaça da caixa de engrenagens russa 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. Engineered specifically for the Siberian Arctic, 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

Lógica Habitacional: The Iron Fortress

A espinha dorsal estrutural desta montagem é a Reducer Housing – Eixo Médio (Parte não. 2502018-A6E). Dentro do Carcaça da caixa de engrenagens russa FAW lógica, 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 Bearing Seat (Parte não. 2502049-A6E), which cradles the input shaft. A precisão geométrica do Carcaça da caixa de engrenagens russa FAW determines the mesh quality of the gears. If the housing flexes under load, tooth contact patterns shift, leading to noise and premature failure. Portanto, the internal ribbing is optimized to handle the separating forces generated by the high-torque helical gears used in this heavy-duty application.

O Carcaça da caixa de engrenagens russa FAW also integrates the mounting points for the differential bearing caps. O Boné – Diff Bearing (Parte não. 2402019-A0E) e Boné – Diff Bearing (Parte não. 2502019-A0E) are machined together with the main housing to ensure perfect concentricity. Esse “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 Carcaça da caixa de engrenagens russa FAW relies on the interaction between the Dirija engrenagem chanfrada (Parte não. 2502036BA6E) e o Equipamento cilíndrico acionado (Parte não. 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. Dentro do Carcaça da caixa de engrenagens russa FAW, the gears run in a bath of specialized gear oil. To prevent aeration and ensure a continuous lubricant film on the gear teeth, a montagem inclui o Oil Shield – Drive Bevel Gear Bearing Seat (Parte não. 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 Noz – Drive Bevel Gear Flange (Parte não. 2402069-A0E), which clamps the Drive Bevel Gear Flange Assembly (Parte não. 2402065-A0E) to the pinion shaft. This connection must withstand the full torque of the engine. The gears within the Carcaça da caixa de engrenagens russa 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.

Lógica de Rotação: Bearings and Preload

Supporting the rotating assemblies within the Carcaça da caixa de engrenagens russa FAW are heavy-duty Rolamento de rolo cônico unidades (Parte não. 32314 e número da peça. 32315). These bearings handle both radial and axial loads generated by the gear mesh. A longevidade do Carcaça da caixa de engrenagens russa FAW depends on precise bearing preload. Isto é conseguido usando Ajustando calço – Drive Bevel Gear Bearing Seat (Números de peças. 2502097-A6E, 2502098-A6E, 2502099-A6E). Technicians stack these shims to set the pinion depth and bearing tightness. No Ártico, thermal contraction of the iron housing can increase preload. Portanto, the assembly specifications for the Carcaça da caixa de engrenagens russa 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 Espaçador – Drive Bevel Gear Bearing (Parte não. 2502088-A0E) e o Ajuste da arruela – Drive Bevel Gear Bearing (Parte não. 2402081-A0E). These components create a rigid spacing between the inner and outer bearings, maintaining the stiffness of the pinion shaft. O Carcaça da caixa de engrenagens russa FAW also utilizes the Anel de ajuste – Rolamento diferencial (Parte não. 2403071-A0E) to set the backlash of the differential carrier bearings. This threaded adjustment allows for fine-tuning of the gear mesh without disassembly. O Locking Plate – Anel de ajuste (Parte não. 2403072-A0E) then secures this setting, preventing the ring from backing out under the intense vibration of off-road driving.

Traction Control: The Pneumatic Lock System

A critical feature housed within the Carcaça da caixa de engrenagens russa FAW is the inter-wheel differential lock. This pneumatic system ensures traction on icy roads. Consiste no Cilindro de Ar – Bloqueio de diferencial entre rodas (Parte não. 2406011-A0E), Pistão – Bloqueio de diferencial entre rodas (Parte não. 2406013-A0E), e Shift Fork – Bloqueio de diferencial entre rodas (Parte não. 2406024-A0E). When activated, the fork pushes the Moving Gear Sleeve – Bloqueio de diferencial entre rodas (Parte não. 2406032-A0E) to engage the Fixed Gear Sleeve – Bloqueio de diferencial entre rodas (Parte não. 2406033-A0E). O Carcaça da caixa de engrenagens russa FAW design ensures that these components are aligned perfectly to prevent binding.

The pneumatic system is sealed by the Anel de vedação – Diff Lock Piston (Parte não. 2406014-55R) e o Junta – Tampa do cilindro de ar (Parte não. 2406017-A0E). O “55R” suffix on the O-ring indicates a special cold-resistant rubber compound that stays flexible at low temperatures, preventing air leaks in the Carcaça da caixa de engrenagens russa FAW. The system is capped by the Cobrir – Cilindro de Ar (Parte não. 2406016-A0E) and secured with Parafuso – Fastening Inter-wheel Diff Lock Air Cylinder Cover (Parte não. 2406018-A0E). O Inter-wheel Diff Lock Switch Assembly (Parte não. 3834050-A0E) provides feedback to the driver, confirming that the axle is locked and ready for low-traction maneuvers.

Segurança de montagem: Parafusos e plugues

A integridade do Carcaça da caixa de engrenagens russa FAW is maintained by high-tensile fasteners. The assembly uses multiple units of Parafuso – Fastening Reducer (Parte não. 2402016-1H) e Parafuso – Fastening Reducer (Parte não. 2402017-1H). These bolts clamp the bearing seats and covers to the main housing. No ambiente de alta vibração de um caminhão basculante, these bolts are installed with thread locker to prevent backing out. O Support Pin – Reducer Housing & Habitação do eixo (Parte não. 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 (Parte não. T62106). This plug, installed in the Carcaça da caixa de engrenagens russa FAW, serve a um duplo propósito: 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 Terminal Elbow Joint (Parte não. CQ63505) for air line connection. The mechanical security of the internal components is further reinforced by the Wire Snap Ring – Diff Lock Fixed Gear Sleeve (Parte não. 2406034-A0E), ensuring that the locking mechanism remains intact under the severe shock loads of engagement.
