Conjunto de eje delantero FAW: Deconstruyendo el 30 Componentes críticos reparables

Bienvenido a esta guía técnica crítica sobre la Conjunto de eje delantero FAW (Número de pieza. 3000010-97R). este es el completo, portador de carga “haz yo” and steering knuckle system for the FAW Jiefang CA4251P66K24T1A3E5 6×4 tractor semirremolque diésel. This assembly is the foundation of the truck’s steering, frenado, y suspensión.

El Conjunto de eje delantero FAW is a non-drive “muerto” eje. Es “lógica” es doble: primero, it must be incredibly strong to support the entire weight of the engine, taxi, and dynamic braking forces. Segundo, it must provide the intricate geometry for the steering system, allowing the wheels to pivot correctly via the kingpins and steering knuckles.

Esta guía detallada es un recurso esencial para técnicos profesionales de chasis y especialistas en piezas.. Deconstruiremos todo Conjunto de eje delantero FAW en su 30 componentes reparables, including the main ‘Front axle’ haz yo, the ‘Left’ y 'correcto’ steering knuckles, the ‘Kingpins’, the brake actuators, and the wheel-speed sensors.

Estructura central: The ‘Front Axle’ (3001011-242)

El corazón de la Conjunto de eje delantero FAW is the ‘Front axle’ (3001011-242). Este es el principal “haz yo” de la asamblea. es un solo, massive piece of forged, acero de alta resistencia. This component is designed to be the primary structural member, bearing the entire front-end load of the vehicle.

This I-beam connects the two front wheels and also serves as the main mounting point for the ‘Front Leaf Spring Assembly’ (ver montaje 502). It is designed to be incredibly rigid, resisting the bending forces from the vehicle’s weight and the twisting (torsional) forces from braking and cornering.

At each end of the I-beam is a precision-machined “yugo” o “eye.” This is where the ‘Kingpin’ (3001044-4mi) esta instalado, creating the critical pivot point for the steering system. un doblado Conjunto de eje delantero FAW haz yo, typically from a severe pothole or collision, is a critical failure that will make the truck undrivable and must be replaced.

El “Steering Logic”: Knuckles (3001031-1050 & 3001032-1050)

El “steering logic” del Conjunto de eje delantero FAW is handled by the steering knuckles. La lista de piezas requiere dos:

• **’Left steering knuckle’ (3001031-1050):** This is the driver’s side component.
• **’Right steering knuckle’ (3001032-1050):** This is the passenger’s side component.

The steering knuckle is a complex, heavy-duty forged component. It holds the wheel hub assembly (which the wheel bolts to) and the brake components. Fundamentalmente, it is designed to pivot. The knuckle is mounted to the “ojo” of the ‘Front axle’ I-beam via the ‘Kingpin’ (3001044-4mi).

The ‘Kingpin’ es el “eje” of the steering pivot. es un grande, hardened steel pin that passes through the knuckle and the I-beam. It is supported by the ‘Hub cone tapered roller bearing’ (3001040-14B) (the kingpin bearing) and a series of ‘Gasket-front pivot’ (3001041-4E to 3001056-4E) cuñas. Estos “según sea necesario” (Bajo demanda) shims are critical for setting the correct preload on the kingpin bearings, ensuring a smooth steering feel without any “jugar” o “wobble.”

The ‘Bushing-pivot’ (3001026AA8S) and ‘Stop-pivot’ (3001036-A0S) provide the wear surfaces and rotational limits for this pivot. This entire sub-assembly is the core of the Conjunto de eje delantero FAW‘s steering capability.

Steering Linkage: Tie Rod and Actuators

El Conjunto de eje delantero FAW also includes the components that connect the steering knuckles to the steering gearbox. The ‘Steering tie-rod assembly (según muestra)’ (3003050-1050-C00) es el “tie rod.” This is the long steel bar that physically connects the ‘Left steering knuckle’ to the ‘Right steering knuckle’. This ensures that when one wheel turns, the other wheel turns with it in a precise, “Ackermann” geometría.

The ‘Right steering knuckle & arm assembly’ (3001020-54W.) and ‘Left steering knuckle & arm assembly’ (3001015-54W.) are the steering arms. These are the levers, bolted to the knuckles, that the ‘Steering tie-rod assembly’ and the drag link (from the steering gearbox) attach to.

A key serviceable part is the ‘Bushing-pivot’ (3001021-54W.), which is the pivot bushing for the steering arm, asegurando un suave, low-friction connection. A failure in the tie-rod or steering arms of the Conjunto de eje delantero FAW will result in a total loss of steering control.

The Brake and Sensor System

El Conjunto de eje delantero FAW provides the foundation for the front braking system. This includes the ‘Front brake bottom plate assembly’ (3501111B1H), cual es el “brake backing plate.” este es el grande, non-rotating plate that holds the brake shoes (for drum brakes) or the caliper (for disc brakes) en su lugar.

Lo más importante, este Conjunto de eje delantero FAW includes the “lógica” para el sistema de frenos antibloqueo (abdominales) and wheel speed sensing. Los detalles de la lista de piezas:

• **’Sensor assembly (dibujo de aprobación pendiente)’ (3550361-6S):** This is the main ABS wheel speed sensor.
• **’Wheel speed sensor assembly’ (3550360-6S):** A secondary or alternative speed sensor.

These are magnetic “hall-effect” sensors that are mounted on the steering knuckle, pointing at a “anillo de tono” (a toothed wheel) on the spinning wheel hub. These sensors send a pulse to the ECU for every tooth that passes, allowing the truck’s computer to know the *exact* speed of each wheel. This is the critical data needed for the ABS (to prevent wheel lock-up), control de tracción (to detect wheel spin), and the speedometer. A failure in this sensor on the Conjunto de eje delantero FAW will disable the ABS and traction control systems, activando una luz de advertencia.
