Conjunto de ruedas y neumáticos FAW: Deconstruyendo el 4 Grupos de componentes críticos

Bienvenido a esta guía técnica crítica sobre la Conjunto de ruedas y neumáticos FAW (Número de pieza. 3101010-75S). este es el completo, road-contacting assembly for the FAW Jiefang CA4251P66K24T1A3E5 6×4 tractor semirremolque diésel. This component is the final link in the powertrain, responsible for supporting the entire vehicle load and providing all traction and braking forces.

El Conjunto de ruedas y neumáticos FAW es un completo, pre-mounted unit, specified here as a 12R22.5 18-ply radial tyre on a 22.5×9.00 rueda. Es “lógica” es proporcionar un duradero, high-load-capacity, and safe connection to the road surface, while also being serviceable for balancing and inflation.

Esta guía detallada es un recurso esencial para los técnicos profesionales., administradores de flotas, y especialistas en repuestos. Deconstruiremos todo Conjunto de ruedas y neumáticos FAW en su 4 principales grupos de componentes reparables, including the high-load-range ‘tyre’, the ‘wheel rim’, the high-pressure ‘valve assembly’, and the critical ‘balance weights’ needed for smooth operation.

Componente central 1: The Tyre (3106010-15W.)

The first serviceable component of the Conjunto de ruedas y neumáticos FAW is the ’12R22.5 18-ply radial tyre’ (3106010-15W.). Este es el “lógica” of the assembly’s load-carrying capacity. Let’s deconstruct its designation:

• **12R22.5:** This defines the size. “12” is the nominal width of the tyre in inches. “R” stands for **Radial Construction**, which is the modern standard for truck tires. It means the plies run radially (en 90 grados) from bead to bead, providing a flexible sidewall for a smoother ride and lower rolling resistance. “22.5” is the diameter of the wheel (borde) in inches.
• **18-ply:** This is the most critical specification for a heavy-duty Conjunto de ruedas y neumáticos FAW. “18-ply” is the Load Range “J” (LRJ). This indicates an extremely strong, reinforced casing and sidewall designed to be inflated to a high pressure (P.EJ., 120 PSI) and safely carry the immense loads of a fully-laden semi-trailer. Using a lower-ply-rated tyre (like a 14-ply) would result in catastrophic tyre failure (a “Reventar”) bajo carga.

Este es un “tubeless” neumático, designed to create an airtight seal directly against the wheel rim, which is a key feature of the modern Conjunto de ruedas y neumáticos FAW.

Componente central 2: The Wheel Rim (3101015A4E)

The ‘22.5×9.00 wheel rim & hub assembly’ (3101015A4E) is the structural “esqueleto” del Conjunto de ruedas y neumáticos FAW. This is the heavy-duty steel (or sometimes forged aluminum) wheel that the tyre is mounted on.

Its size, **22.5×9.00**, es critico. El “22.5” inch diameter must exactly match the tyre. El “9.00” inch width is the specified rim width for a 12R tyre, ensuring the tyre’s “beads” are properly seated for a safe, sello hermético. This assembly is broken down into its two welded components: the ‘wheel rim (sección)’ (3101021A4E), which is the outer “hoop,” and the ‘wheel hub/disc’ (3101036A4E), which is the center disc that bolts to the truck’s axle.

This wheel is a “hub-piloted” diseño, meaning it is centered on the axle by the large center bore, not by the lug nuts (as in older “stud-piloted” sistemas). This provides a more accurate, vibration-free mounting. A bent or cracked rim is a critical failure of the Conjunto de ruedas y neumáticos FAW, as it will not hold air and will cause a dangerous wheel “wobble.”

Componente central 3: The Valve Stem (3101055A4E)

The ‘V3.20.12 (código ETRTO) Tubeless inner tube valve assy for trucks’ (3101055A4E) is the high-pressure valve stem. This is not the small, goma “snap-in” valve seen on a passenger car. Este es un trabajo pesado, totalmente metálico (brass and steel) “bolt-in” valve assembly.

Es “lógica” is to reliably hold the 100-120 PSI of air pressure required by the 18-ply tyre. It is mounted through a hole in the wheel rim and sealed with high-pressure rubber grommets and a locking nut. This creates a permanent, durable seal that can withstand the extreme heat from braking and the high centrifugal forces.

A failure of this valve in the Conjunto de ruedas y neumáticos FAW would result in a rapid, if not catastrophic, loss of air pressure, conduciendo a un “Reventar” and a loss of vehicle control. es un pequeño, but critically important, safety component of the Conjunto de ruedas y neumáticos FAW.

Componente central 4: Los pesos de equilibrio (3101060-1104 Serie)

The final group in the Conjunto de ruedas y neumáticos FAW is the ‘9.0 Balance weight assembly’ colocar (P.EJ., 3101060-1104, 3101065-1104, 3101085-1104 50GRAMO, etc.). The parts list critically marks these as “Bajo demanda” o “**As needed**.”

Este es el “balancing logic” del Conjunto de ruedas y neumáticos FAW. No tyre and wheel are perfectly balanced from the factory; they will always have a “heavy spot.” When this heavy spot spins at highway speeds, it creates an “out-of-balance” force that causes the wheel to “hop” y “wobble.” This vibration is not just annoying to the driver; it is destructive, causando “cupped” tire wear and destroying the truck’s kingpins, wheel bearings, and steering components.

Estos “balance weights” are the solution. A technician places the entire Conjunto de ruedas y neumáticos FAW en un “spin balancer,” which identifies the location and mass of the heavy spot. The technician then “counteracts” this by adding these weights (P.EJ., a ’50G’ or 50-gram weight) to the opposite side of the wheel rim.

El “9.0” designation refers to the 9.00-inch rim, asegurando el “clip-on” weight has the correct profile to securely attach to the rim flange. El “según sea necesario” logic means that every Conjunto de ruedas y neumáticos FAW will require a different combination of these weights to achieve a perfect, liso, and vibration-free ride.
