Power Entry: The Flange and Seal Interface

The primary interface for power delivery in the Engrenagem de redução do eixo traseiro russo FAW é o Drive Bevel Gear Flange Assembly (Parte não. 2402065-A0E). This heavy-duty forged component connects the driveshaft to the input pinion. Securing this high-torque connection is the Noz – Drive Bevel Gear Flange (Parte não. 2402069-A0E), which applies the necessary clamping force to maintain the integrity of the pinion bearing stack. In the harsh operational environment of a Russian mine, ensuring this flange remains rigid is critical to preventing vibration-induced wear.

Protecting the internal precision components from the external elements is the Drive Bevel Gear Oil Seal Assembly (Parte não. 2402055-55R-C00). O “55R” designation highlights the cold-weather specification of the elastomer used in this seal. Standard rubber seals would become brittle and crack at -40°C, leading to catastrophic oil loss. This specialized seal ensures that the gear oil remains inside the Engrenagem de redução do eixo traseiro russo FAW while effectively excluding abrasive silica dust, água, and road salts that could corrode the bearings.

The input shaft is supported by high-capacity Rolamento de rolo cônico unidades (Parte não. 30314 e 32315). These bearings are housed within the Bearing Seat – Dirija engrenagem chanfrada (Parte não. 2402049-A0E). An Oil Shield – Drive Bevel Gear Bearing Seat (Parte não. 2402048-A0E) is strategically placed to manage oil flow, preventing aeration and ensuring a continuous lubricant film. This attention to fluid dynamics is essential for the Engrenagem de redução do eixo traseiro russo FAW to withstand high-speed transport operations without overheating.

Reduction Logic: Hypoid Gears and Shimming

The core of the reduction system is the Dirija engrenagem chanfrada (Parte não. 2402036BA6E), commonly known as the pinion. No Engrenagem de redução do eixo traseiro russo FAW, this gear utilizes a hypoid tooth profile to maximize the contact patch and strength. The metallurgy is optimized for shock resistance, a necessary trait when the vehicle experiences sudden traction changes on icy surfaces. The gear ratio (i=1.500) is calculated to provide the immense low-end torque required for starting a fully loaded dump truck on a steep incline.

Precise alignment of the pinion depth and bearing preload is achieved through the use of the Ajuste da arruela – Drive Bevel Gear Bearing (Parte não. 2402081-A0E) e o Espaçador – Drive Bevel Gear Bearing (Parte não. 2402088-A0E). Além disso, Ajustando calço – Drive Bevel Gear Bearing Seat (Números de peças. 2402097-A0E, 2402098-A0E, 2402099-A0E) allow technicians to fine-tune the gear mesh pattern to micron-level tolerances. This precision prevents gear whine and ensures even wear distribution across the tooth face of the Engrenagem de redução do eixo traseiro russo FAW.

The structural rigidity of the gear set is maintained by the Parafuso – Fastening Reducer (Parte não. 2402016-1H). There are 12 of these high-tensile bolts securing the bearing seat to the main housing. No Engrenagem de redução do eixo traseiro russo FAW, these fasteners are torqued to yield to prevent loosening under vibration. The robust nature of these bolts ensures that the separating forces generated by the hypoid gear action do not distort the housing, maintaining gear alignment throughout the service life of the component.

Differential Logic: The 2403010BA6E Assembly

Housed within the main casing is the Differential Assembly (Parte não. 2403010BA6E). This unit allows the rear wheels to rotate at different speeds during cornering while transmitting power. The carrier assembly is supported by bearings whose preload is set via the Anel de ajuste – Rolamento diferencial (Parte não. 2403071-A0E). No Engrenagem de redução do eixo traseiro russo FAW, these adjusting rings are threaded into the housing, allowing for precise setting of both the backlash and the carrier bearing preload without disassembly.

To ensure these settings do not drift during operation, o Lock Plate – Anel de ajuste (Parte não. 2403072-A0E) is utilized. This simple but vital component locks the adjusting ring in place, preventing rotation. O Support Pin – Reducer Housing & Habitação do eixo (Parte não. 2402021-A0E) ensures perfect alignment between the reducer assembly and the axle housing proper. Any misalignment here in the Engrenagem de redução do eixo traseiro russo FAW would lead to axle shaft runout and seal failure.

The differential carrier itself is cast from high-grade nodular iron to resist the centrifugal forces at high RPMs and the internal pressure of the gear separation forces. O Parafuso – Fastening Differential Bearing Cap (Parte não. 2402023-A0E) secures the main caps over the bearings. These bolts are critical safety components; their failure would result in the differential breaking loose inside the axle. O Engrenagem de redução do eixo traseiro russo FAW utilizes premium fasteners to guarantee structural integrity under the heaviest payloads.

Traction Control: Pneumatic Locking System

A defining feature of the Engrenagem de redução do eixo traseiro russo FAW is the integrated inter-wheel differential lock system. This mechanism is actuated pneumatically via the Air Cylinder – Inter-wheel Diff Lock (Parte não. 2406011-A0E). When the driver engages the switch, air pressure moves the Pistão – Inter-wheel Diff Lock (Parte não. 2406013-A0E). This piston pushes the Shift Fork – Inter-wheel Diff Lock (Parte não. 2406024-A0E) to engage the locking mechanism.

The physical locking is achieved by the engagement of the Moving Gear Sleeve – Inter-wheel Diff Lock (Parte não. 2406032-A0E) with the Fixed Gear Sleeve – Inter-wheel Diff Lock (Parte não. 2406033-A0E). This action mechanically locks the left and right axle shafts together, forcing both wheels to turn at the same speed. In the deep mud or snow of the Russian tundra, this feature is indispensable. O Engrenagem de redução do eixo traseiro russo FAW ensures that traction is maintained even if one wheel is completely airborne.

Reliability of this system is ensured by the Spring de retorno – Inter-wheel Diff Lock (Parte não. 2406028-A0E), which disengages the lock when air pressure is removed. O Wire Snap Ring – Diff Lock Fixed Gear Sleeve (Parte não. 2406034-A0E) secures the fixed components. Além disso, o Inter-wheel Diff Lock Switch Assembly (Parte não. 3834050-A0E) provides feedback to the driver, confirming engagement. The sealing of the pneumatic cylinder is handled by the Anel de vedação – Diff Lock Piston (Parte não. 2406014-55R), using cold-resistant materials to prevent leaks in the Engrenagem de redução do eixo traseiro russo FAW.

Conclusão: The Pinnacle of Traction Engineering

O Engrenagem de redução do eixo traseiro russo FAW is the ultimate enabler of all-terrain mobility. By combining high-precision hypoid gears with a robust, pneumatically actuated differential lock, FAW has created a rear drive unit that offers both highway efficiency and unstoppable off-road traction. The careful selection of cold-resistant materials for seals and gaskets ensures that this performance is maintained even in the harshest Siberian winters.

Para operadores de frota, the complexity of this assembly underscores the need for genuine parts.
