Suspensión trasera FAW: Un enfoque crítico sobre la 35 Componentes de un 6×4 Transmisión

Bienvenido a esta guía técnica crítica sobre la Suspensión trasera FAW asamblea (Asamblea 509). este es el completo, trabajo pesado “tandem-axle” suspension system for the FAW Jiefang CA4251P66K24T1A3E5 6×4 tractor semirremolque diésel. This is the assembly that handles the entire payload and provides traction.

El Suspensión trasera FAW es un “lógica” system known as a “balance beam” o “muñón” suspensión. Its design is critical for a 6×4 tractor, as it is engineered to articulate and “caminar” over uneven terrain, ensuring all eight rear wheels remain in contact with the ground for maximum traction and load distribution.

Esta guía detallada es un recurso esencial para los técnicos de chasis profesionales., administradores de flotas, y especialistas en repuestos. Deconstruiremos todo Suspensión trasera FAW en su 35 tipos de componentes reparables, including the ‘Rear leaf spring assembly’, the ‘Balance suspension bracket’, the ‘Thrust rods’, and the vast array of high-tensile fasteners that hold this high-stress system together.

Componente central: The ‘Rear Leaf Spring Assembly’ (2912010-2000)

El corazón de la Suspensión trasera FAW is the ‘Rear leaf spring assembly’ (2912010-2000). The list calls for two of these—one for each side of the truck. Unlike a front suspension, this is an “inverted” leaf pack. El “embalar” consists of multiple leaves of high-carbon spring steel, such as ‘Rear leaf spring-first leaf’ (2912011-2000) through ‘Rear leaf spring-fourth leaf’ (2912014-2000).

El “lógica” de esto Suspensión trasera FAW is completely different from the front. The center of this spring pack (held by ‘Center bolt-rear leaf spring’ 2912161-70A) rests on the ‘Balance suspension bracket’ (muñón), which is the central pivot point on the chassis. The *ends* of the spring pack rest on the two rear drive axles.

Esto crea un “viga para caminar” efecto. When the front-most drive axle hits a bump, it pushes *up* on the front of the spring pack; este, Sucesivamente, forces the *back* of the spring pack *down*, pushing the rear-most drive axle onto the ground. Este “caminando” articulation is the core logic of the Suspensión trasera FAW, ensuring constant, maximum traction for both axles.

El “Lógica”: ‘Balance Suspension Bracket’ (Trunnion)

The central pivot for this “caminando” Suspensión trasera FAW is the ‘Balance suspension bracket’ asamblea (ver montaje 499). This is the heavy-duty bracket that mounts to the truck’s frame rail. The parts in this list are what attach the leaf spring *to* that trunnion.

The ‘Balance suspension bracket pin upper/lower cover’ (2918041-1057, 2918046-1057) and ‘Bushing-balance suspension bracket pin’ (2918042-242) formar el “cojinete” that the leaf spring pack pivots on.

The ‘Cover-balance suspension bracket spring’ (2918072-1050) es el “tapa” that holds the spring pack down onto this trunnion. todo esto “lógica” assembly is what allows the inverted ‘Rear leaf spring assembly’ to pivot in the center, creando el “walking beam.” This is the most critical pivot point in the entire Suspensión trasera FAW.

Axle Connection: U-Bolts and Thrust Rods

El Suspensión trasera FAW must not only support weight, but it must also hold the two drive axles in perfect alignment. This is done by two systems.

**1. Pernos en U:** The ‘U-bolt-fasten rear leaf spring’ (2912411-70A) unidades (4 total) son lo que “abrazadera” the axles *to* the ends of the leaf spring packs. They pass through the ‘Cover-rear leaf spring’ (2912406-1057) and are secured by the eight ‘Nut-fasten U-bolt’ (2912413-5h). This is the primary vertical connection.

**2. Thrust Rods:** Leaf springs are not strong enough to handle the immense acceleration and braking torque (which tries to “girar” el eje). Este es el trabajo del “barra de empuje” (o “torque rod”) sistema. Este Suspensión trasera FAW parts list includes the ‘Upper front/rear connecting rod with rubber bushing’ (2919005-242, 2919015-242) and the ‘Lower front/rear connecting rod with rubber bushing’ (2919010-242, 2919020-242).

Este “lógica” crea un “four-link” system for each axle. These four rods (two upper, two lower) form a rigid “caja” that connects the axle directly to the frame, forcing it to stay perfectly aligned. The ‘Support-upper reaction rod and vehicle frame connecting’ (2919111-2000) is the chassis-side bracket for these rods. This thrust rod system is the “lógica” that handles all the acceleration and braking forces, dejando el Suspensión trasera FAW leaf springs to simply handle the vertical load.

Sujetadores críticos: El 100+ Piece Hardware Set

El Suspensión trasera FAW es un alto estrés, high-vibration assembly held together by over 100 sujetadores especializados. A single failed bolt here could be catastrophic.

**SPL Self-Locking Nuts (T327-series):** The parts list calls for a total of **52** ‘SPL hex small flange lock nuts’ (T32718TF2, T32720TF2, T32724TF2). Este es el “lógica” of a modern, high-safety Suspensión trasera FAW. Estos son “Stover” o “par predominante” tuercas de seguridad. The top of the nut is intentionally crimped or deformed, creating an “elastic” lock that grips the bolt threads. This makes them *immune* to vibration and *must* be used for all critical connections, especially on the thrust rods.

**Pernos de brida (Q185-series):** The list calls for over 40 'Pernos de brida hexagonal’ (Q1851875T, Q1851850T, Q1852060T, Q1852090T, Q1851860T). El “brida” head acts as an integrated washer to spread the clamping load. El “t” suffix denotes a high-tensile (P.EJ., 10.9) fortaleza, essential for handling the shear forces of the Suspensión trasera FAW.

**Flange Nuts (C039714):** El 12 ‘Hex flange nuts’ provide a wide, secure clamping base for other non-locking-nut applications. This comprehensive, over-engineered fastener set is the “lógica” que asegura la Suspensión trasera FAW stays intact under the most extreme conditions.
