Conjunto de freno centro-derecho ruso FAW: Deconstruyendo 49 Componentes estratégicos para la gestión de carga en el Ártico

El Freno central derecho ruso FAW assembly is the pivotal deceleration unit for the right-hand drive wheel of the middle axle on the CA3250P66K24L1TE5Z 6×6 camión volcado. Engineered to balance the braking torque of the tandem bogie, this assembly features a unique camshaft profile and adjuster orientation tailored for the right-side actuation geometry. Operating in the extreme cold of the Russian mining sector, el Freno central derecho ruso FAW ensures stable, skid-free stopping power on icy gradients. This guide provides a detailed breakdown of the S-cam mechanism, friction linings, and heavy-duty return springs that define the performance of the Freno central derecho ruso FAW.

Freno central derecho ruso FAW

Optimized for Tandem Axle Dynamics

El Freno central derecho ruso FAW assembly is a critical component of the FAW J6P’s 6×6 tren motriz, specifically mounted on the right side of the middle axle. This location subjects the brake unit to unique torsional forces generated by the inter-axle differential and the walking beam suspension. To counter these loads, the assembly incorporates the heavy-duty Middle Axle Right Spring Cylinder with Quick Connector Assy (Número de pieza. 3530040-896-C00). This powerful actuator ensures immediate response for both service braking and emergency holding, preventing yaw instability on the slippery surfaces common in Russian mining operations.

Unlike standard rear brake setups, el Freno central derecho ruso FAW requires specialized mounting hardware. El Middle Axle Right Camshaft Bracket (Número de pieza. 3503128-A0E) is engineered with specific clearances to accommodate the movement of the tandem suspension. This bracket is secured to the axle housing using high-strength Perno de bloqueo – Soporte del árbol de levas sujetadores (Número de pieza. 3503038-A0E y 3503039-A0E), which are torqued to resist loosening under the intense vibration of off-road driving.

While sharing the robust 410mm drum and Forro de fricción trasero colocar (Número de pieza. 3502406-A6E / 3502407-A6E) with the rear axle for parts interchangeability, el Freno central derecho ruso FAW features distinct actuation tuning. El Middle Axle Right Brake Adjuster Arm Assembly (Número de pieza. 3503210-A0E) is calibrated to synchronize braking force with the rest of the bogie, ensuring that the middle axle contributes its full share of deceleration without locking up prematurely, which could lead to tire flat-spotting and loss of steering control.

Precision Camshaft and Bearing Engineering

En el corazón de la Freno central derecho ruso FAW es el Rear Right Brake Camshaft (Número de pieza. 3502152-A6E), adapted for the middle axle application. This S-cam features a reverse helix profile to actuate the right-side shoes against the drum’s rotation. It is supported by the Conjunto de cojinete de junta del árbol de levas (Número de pieza. 3502135-A0E), a spherical bearing design that accommodates the slight axle flex inherent in heavy-load operations, preventing the camshaft from binding and ensuring smooth modulation.

To protect these critical moving parts, el Freno central derecho ruso FAW employs a robust sealing system. El Sello de aceite – Soporte del árbol de levas (Número de pieza. 3502153-A0E) works in tandem with the Asiento – Sello de aceite (Número de pieza. 3502124-A0E) to create an impermeable barrier against road grime, agua, and abrasive mining dust. Maintaining these seals is vital for the longevity of the camshaft journals, as contaminant ingress can lead to rapid wear and seizure.

Accurate end-play adjustment is achieved through the use of the Calza de ajuste de freno (Número de pieza. 3501156A392) y Espaciador – Soporte del árbol de levas (Número de pieza. 3502123-A0E). These components center the camshaft within the drum, ensuring the S-head engages the rollers squarely. Proper shimming is a critical maintenance step for the Freno central derecho ruso FAW, guaranteeing that the automatic slack adjuster can effectively maintain the correct lining-to-drum clearance for optimal braking performance.

Friction System and Environmental Protection

The friction generation mechanism of the Freno central derecho ruso FAW relies on the massive Zapata de freno trasera (Número de pieza. 3502391-A6E). These shoes are anchored by the Eje de zapata de freno trasero / Pasador de anclaje (Número de pieza. 3502086-A6E) and retracted by the heavy-duty Resorte de retorno (Número de pieza. 3502436-A0E). The springs are manufactured from high-tensile wire to ensure rapid shoe retraction, preventing brake drag that could overheat the wheel end—a critical safety concern in winter operations where heat can cause snow to melt and refreeze as ice on the brakes.

To defend against the harsh environment, el Freno central derecho ruso FAW is encased by the Protector contra polvo trasero del freno trasero (Número de pieza. 3502031-A0E) y Protector contra polvo delantero del freno trasero (Número de pieza. 3502032-A0E). These interlocking steel plates prevent rocks, lodo, and ice from entering the drum and damaging the friction surfaces. Los puertos de inspección están sellados con el Enchufar – Orificio de inspección del protector contra el polvo (Número de pieza. 3501034-02), allowing for quick visual checks of lining wear without exposing the internal components to the elements.

The mechanical interface between the shoes and the S-cam is refined by the Zapata de freno trasero con conjunto de rodillo (Número de pieza. 3502375-A6E). Este conjunto incluye el Rodillo de zapata de freno (Número de pieza. 3502392-A0E) y Rollero (Número de pieza. 3502394-A0E), which reduce friction and hysteresis. El Buje de rodillo (Número de pieza. 3502393-A0E) is designed to operate effectively even when grease viscosity increases in extreme cold, ensuring consistent and predictable braking response.

Component Retention and Serviceability

El Freno central derecho ruso FAW utilizes robust retention methods to ensure component security. The anchor pins are held in place by the Placa de retención del eje de zapata de freno (Número de pieza. 3502087-A6E) y bloqueado con el Placa de bloqueo (Número de pieza. 3501087-4mi). This redundant system prevents the pins from migrating under the torsional vibration of braking. Además, Anillo de retención del eje unidades (Número de pieza. Q43112 y Q43122) Asegure los rodillos y los puntos de pivote., maintaining the assembly’s internal geometry.

Routine maintenance is simplified by the inclusion of Engrasador recto (Número de pieza. CQ70001) points on the camshaft bracket and slack adjuster. These fittings allow fresh lubricant to be purged into critical wear areas, flushing out old grease and contaminants. En el Freno central derecho ruso FAW, regular lubrication extends the life of the Cojinete – Zapata (Número de pieza. 3501396-A0S) y cojinetes de árbol de levas, reducing long-term operating costs.

The structural integrity of the assembly is anchored by the Soporte de freno trasero (Número de pieza. 3502021-A0E), which is bolted to the axle housing with Perno de bloqueo – Para soporte de freno (Número de pieza. 3502038-487). These bolts must be torqued to specific values to withstand the immense shear forces generated during braking. By using genuine Remache (Número de pieza. 3502408-A0E) and adhering to the parts list for the Freno central derecho ruso FAW, operators ensure the continued safety and reliability of their heavy-duty fleet.
