Bienvenido a esta guía técnica crítica sobre la Conjunto de resorte de hoja delantera FAW (Número de pieza. 2902010A50A). This is the complete front-end suspension system for the FAW Jiefang CA4251P66K24T1A3E5 6×4 tractor semirremolque diésel. This assembly is responsible for supporting the entire weight of the cab, motor, and transmission, while also absorbing road shock.
El Conjunto de resorte de hoja delantera FAW es un trabajo pesado, multi-leaf pack designed for durability and load-carrying capacity. Es “lógica” es proporcionar una fuerte, flexible connection between the solid front axle and the truck’s frame. It must be strong enough to prevent axle movement, yet flexible enough to provide a reasonable ride quality.
Esta guía detallada es un recurso esencial para técnicos de suspensión y administradores de flotas profesionales.. Deconstruiremos todo Conjunto de resorte de hoja delantera FAW en su 46 componentes reparables, including the main spring pack, individual leaves, U-bolts, amortiguadores, and the critical stabilizer bar.
El corazón de la Conjunto de resorte de hoja delantera FAW es el 'Conjunto de ballesta delantera’ (2902010A50A), de los cuales hay dos (one for the left and one for the right side). Este es el principal “spring pack.” No es una sola pieza de acero., but a carefully engineered stack of multiple “hojas” of high-carbon spring steel.
This multi-leaf design is the core “lógica” del Conjunto de resorte de hoja delantera FAW. It provides a “progressive” spring rate. Cuando el camión está descargado, solo la parte superior, las hojas más largas se flexionan, proporcionando un (relativamente) paseo más suave. As the truck is loaded, or when it hits a large bump, la carga se transfiere al más corto, hojas más gruesas, aumentando drásticamente la rigidez y evitando que la suspensión “tocando fondo.”
This parts list breaks the pack down into its serviceable leaves, including the ‘Front leaf spring-first leaf’ (2902011A50A), ‘Resorte de hoja delantera-segunda hoja’ (2902012A50A), ‘Front leaf spring-third leaf’ (2902013A50A), and the ‘Hanger-rear spring eighth leaf’ (2912139-116). These leaves are all held together by the ‘Center bolt-front leaf spring’ (2902161-40A) and are kept in alignment by ‘Clips’ (2902131-50A).
El Conjunto de resorte de hoja delantera FAW must be connected to the truck in two ways: debe ser “colgado” from the frame, and it must be “sujetado” to the axle.
**1. Reprimición (Pernos en U):** The ‘U-bolt-front leaf spring’ (2902411-56B y 2902411-92V) units are the primary fasteners. These two large, U-shaped bolts loop *over* the axle and *through* a ‘Cover-front leaf spring’ (2902406-50A). They are secured from below by the ‘Nut-fasten U-bolt’ (2902413-76A) and ‘Hex nuts’ (CQ34114, CQ35010). Este “Perno en U” assembly is what rigidly clamps the middle of the Conjunto de resorte de hoja delantera FAW to the axle, forcing the axle to move with the spring.
**2. Hanging (Shackles):** El “ojos” (fines) of the spring pack are attached to the chassis frame. The front eye bolts into a fixed “hanger” (see assembly 499). The rear eye attaches to a “shackle” (a swinging link, not fully detailed here). Este “shackle” logic is what allows the Conjunto de resorte de hoja delantera FAW to get longer and shorter as it flexes.
A spring, by itself, voluntad “bounce” uncontrollably after hitting a bump. El “damping” logic for the Conjunto de resorte de hoja delantera FAW is provided by the ‘Lower left support bracket assy-front shock absorber’ (2905425-2000) and the ‘Lower right support bracket assy-front shock absorber’ (2905430-2000).
These are the heavy-duty brackets that mount the *bottom* of the shock absorbers to the front axle. El amortiguador (a hydraulic piston) works against the spring: as the spring compresses and rebounds, the shock absorber provides resistance, “damping” the oscillation and forcing the tire to stay in contact with the road.
Sin estos corchetes, the shock absorbers cannot be mounted, and the truck would be dangerously unstable, “fuerte” after every bump. A crack in one of these brackets is a critical safety failure. This sub-assembly is a key part of the Conjunto de resorte de hoja delantera FAW‘s function.
la final “lógica” del Conjunto de resorte de hoja delantera FAW is lateral stability, provided by the ‘Bracket-front lateral stabilizer’ (2906444-50A). These two brackets are used to mount the truck’s “stabilizer bar” (also known as an “barra estabilizadora”) al chasis.
The stabilizer bar is a long, torsion-bar spring that connects the *left* side of the axle to the *right* side of the chassis. When the truck enters a corner, “balanceo del cuerpo” causes the outside suspension to compress and the inside suspension to extend.
The stabilizer bar’s “lógica” is to resist this twisting motion. It transfers the force from the compressed (outside) spring to the extended (inside) primavera, forcing the inside wheel down and “levantamiento” the outside of the cab. This action keeps the truck much flatter during cornering, which is a critical safety and handling feature. These brackets are the foundation for this system, making them a key part of the Conjunto de resorte de hoja delantera FAW.
El Conjunto de resorte de hoja delantera FAW is a high-friction, high-impact system. It relies on several “sacrificatorio” wear items to protect the main components.
**’Damping pad-front leaf spring’ (2902137A50A):** The parts list calls for eight of these. These are small, hard polymer or nylon pads that are inserted *between* the ends of the individual spring leaves. As the Conjunto de resorte de hoja delantera FAW flexes, the leaves slide against each other. These pads prevent metal-on-metal “raspando,” which would cause the springs to squeak and wear out prematurely.
**’Gasket-front leaf spring’ (2902211-50A):** The six gaskets are “insulators,” likely placed between the U-bolt’s ‘Cover’ (2902406-50A) and the spring pack, and between the axle seat and the spring pack, to provide a final layer of vibration damping and prevent metal-on-metal contact.
**’Bushing-rear leaf spring’ (2912121-03):** This is the bushing for the rear “ojo” of the spring pack, where it connects to the shackle. This rubber bushing is designed to absorb the high-frequency vibrations from the road, preventing them from being transmitted into the Conjunto de resorte de hoja delantera FAW and the chassis.
