Suporte de suspensão central russo FAW: Ancoragem 15 Componentes principais para estabilidade do eixo tandem

O Suporte de suspensão central russo FAW logic assembly is the structural backbone of the middle axle bogie on the CA3250P66K24L1TE5Z dump truck. This complex component cluster performs the essential function of rigidly locating the axle housing while providing anchor points for the torque-resisting reaction rods. Engineered with “55R” e “64C” arctic-grade materials, o Suporte de suspensão central russo FAW withstands the immense compressive, torsional, and longitudinal forces generated by heavy hauling over frozen, rutted terrain. This guide analyzes the leaf spring seat, the upper and lower rod anchors, and the high-strength fastening logic.

Leaf Spring Seat and Load Path Interface

The foundation of the **FAW Russian Centre Suspension Bracket** begins with the leaf spring seats. This assembly includes the **Rear Leaf Spring Seat Assembly** (Parte não. 2912445-55R and Part No. 2912450-55R), which directly contacts the axle housing. The seat must transfer the entire vertical payload from the springs into the axle housing while preventing axle wrap—the rotational movement of the axle under high torque. The casting geometry, such as **Rear Leaf Spring Seat – Middle Left** (Parte não. 2912441-55R), is specifically designed to maximize the friction grip with the leaf spring pack.

Integrated into the seat is the critical damping mechanism. The **Cushion & Locating Pin Assembly** (Parte não. 2912405-55R) uses a **Cushion – Rear Leaf Spring Seat** (Parte não. 2912402-55R) made from arctic-grade elastomer. This cushion absorbs the final stages of high-impact compression, preventing metal-on-metal contact between the spring and the axle. O “55R” specification ensures the cushion remains flexible at -50°C, unlike standard rubber which would freeze and shatter. The **FAW Russian Centre Suspension Bracket** depends on this cushion to mitigate shock loads.

The **Cushion & Locating Pin Assembly** also includes the **Elastic Cylindrical Pin** (Parte não. 2919201-A2E) and the **Locating Pin** itself, which index the spring pack to the seat. This indexing is critical for alignment. If the leaf spring shifts longitudinally, the entire axle moves, causing misalignment and rapid tire wear. The integrity of the **FAW Russian Centre Suspension Bracket** is maintained by ensuring the pin remains securely seated in the axle housing.

Reaction Rod Anchor Points and Torque Management

The mounting points for the torque-resisting reaction rods are integral to the **FAW Russian Centre Suspension Bracket**. The **Reaction Rod Upper Bracket with Locating Pin Assy – Middle Axle** (Parte não. 2919210A64W) and its main bracket (**Reaction Rod Upper Bracket – Middle Axle**, Parte não. 2919211A64W) resist the axle’s torque reaction during acceleration. O “64C” code indicates a high-strength steel alloy optimized for impact toughness, preventing brittle fracture in the cold.

The lower anchor points are provided by the **Reaction Rod Lower Bracket Welding Assembly** (Parte não. 2919310-A7E). This heavily reinforced structure bolts directly to the axle housing. It must resist the massive braking forces and longitudinal thrust of the truck. The welding integrity of the **FAW Russian Centre Suspension Bracket** component is crucial; a failed weld here would allow the axle to shift, causing a catastrophic loss of control.

The mounting eyes of the reaction rod brackets utilize the **Elastic Cylindrical Pin** (Parte não. 2919202-A2E) to allow controlled articulation of the rod ends while preventing axial movement. This pin is subjected to extreme shear forces. O Suporte de suspensão central russo FAW assembly depends on these pins to maintain the precise pinion angle of the differential. Any wear in these pivot points leads to driveline vibration and accelerated U-joint failure.

Fastening Architecture and Component Security

The **FAW Russian Centre Suspension Bracket** is secured by an array of high-tensile fasteners. The **Hexagon Head Bolt** (Parte não. CQ15120130T and Part No. CQ1512060T) are Grade 10.9 or higher, ensuring they can handle the required shear and tensile loads. The **Hexagon Flange Bolt (Haste Grossa)** (Parte não. Q18420130TF38K and Part No. Q1842070TF38K) are used in high-stress areas for superior clamping force. The flange design increases the friction grip, preventing the brackets from moving on the axle housing.

The bolts feature specialized anti-corrosion coatings (TF38K suffix) for arctic durability. This protects the threads from rust seizure caused by road salt, ensuring that the **FAW Russian Centre Suspension Bracket** can be serviced after years of exposure. The bolts must be torqued to precise specifications to create the necessary friction lock. Under-torquing is the leading cause of **FAW Russian Centre Suspension Bracket** failure, as the full load is then placed on the bolt shank.

Redundancy is built into the **FAW Russian Centre Suspension Bracket** mounting system. The high quantity of bolts, combined with the use of locator pins, ensures that the axle remains secured even if one or two bolts were to vibrate loose. No entanto, fleet mechanics must perform regular torque checks, especially after the first major service interval, to preserve the structural integrity of the **FAW Russian Centre Suspension Bracket** and prevent fretting corrosion.

Maintenance and Cold-Weather Service

Proactive maintenance of the **FAW Russian Centre Suspension Bracket** is essential for vehicle uptime. Visual inspection should focus on the **Cushion** (Parte não. 2912402-55R) for signs of cracking or disintegration, which compromises the damping. The **Elastic Cylindrical Pin** (Parte não. 2919201-A2E) should be checked for excessive play. Any sign of looseness in the **FAW Russian Centre Suspension Bracket** indicates imminent failure and demands immediate attention.

When replacing components, only genuine FAW parts should be used. O “55R” cushion and the “64C” bracket material are non-negotiable specifications for arctic operation. Using standard parts in the **FAW Russian Centre Suspension Bracket** assembly will lead to rapid failure and pose a significant safety risk. The integrity of the **Reaction Rod Lower Bracket Welding Assembly** (Parte não. 2919310-A7E) should be checked regularly for weld failure.

The complexity of the **FAW Russian Centre Suspension Bracket** demands professional service. Correctly indexing the spring seat using the locating pins and setting the alignment of the reaction rod brackets ensures the truck’s driveline geometry is preserved. This meticulous attention to detail is what guarantees the long-term reliability of the CA3250P66K24L1TE5Z in the heavy-haul segment.
