Conjunto de rodas e pneus FAW: Desconstruindo o 4 Grupos de componentes críticos

Bem-vindo a este guia técnico crítico sobre o Conjunto de rodas e pneus FAW (Parte não. 3101010-75S). Este é o completo, road-contacting assembly for the FAW Jiefang CA4251P66K24T1A3E5 6×4 trator semirreboque diesel. This component is the final link in the powertrain, responsible for supporting the entire vehicle load and providing all traction and braking forces.

O Conjunto de rodas e pneus FAW é um completo, pre-mounted unit, specified here as a 12R22.5 18-ply radial tyre on a 22.5×9.00 roda. Isso é “lógica” é fornecer um durável, high-load-capacity, and safe connection to the road surface, while also being serviceable for balancing and inflation.

Este guia detalhado é um recurso essencial para técnicos profissionais, gestores de frota, e especialistas em peças. Vamos desconstruir todo Conjunto de rodas e pneus FAW em seu 4 main serviceable component groups, including the high-load-range ‘tyre’, the ‘wheel rim’, the high-pressure ‘valve assembly’, and the critical ‘balance weights’ needed for smooth operation.

Componente principal 1: The Tyre (3106010-15C)

The first serviceable component of the Conjunto de rodas e pneus FAW is the ’12R22.5 18-ply radial tyre’ (3106010-15C). Este é o “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 (at 90 graus) from bead to bead, providing a flexible sidewall for a smoother ride and lower rolling resistance. “22.5” is the diameter of the wheel (aro) in inches.
• **18-dobrar:** This is the most critical specification for a heavy-duty Conjunto de rodas e pneus FAW. “18-dobrar” is the Load Range “J” (LRJ). This indicates an extremely strong, reinforced casing and sidewall designed to be inflated to a high pressure (Por exemplo, 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 “blowout”) sob carga.

Este é um “tubeless” pneu, designed to create an airtight seal directly against the wheel rim, which is a key feature of the modern Conjunto de rodas e pneus FAW.

Componente principal 2: The Wheel Rim (3101015A4E)

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

Its size, **22.5×9.00**, é crítico. O “22.5” inch diameter must exactly match the tyre. O “9.00” inch width is the specified rim width for a 12R tyre, ensuring the tyre’s “beads” are properly seated for a safe, airtight seal. This assembly is broken down into its two welded components: the ‘wheel rim (seção)’ (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” projeto, 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 rodas e pneus FAW, as it will not hold air and will cause a dangerous wheel “wobble.”

Componente principal 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, borracha “snap-in” valve seen on a passenger car. Este é um serviço pesado, todo em metal (brass and steel) “bolt-in” valve assembly.

Isso é “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 rodas e pneus FAW would result in a rapid, if not catastrophic, loss of air pressure, levando a um “blowout” and a loss of vehicle control. É um pequeno, but critically important, safety component of the Conjunto de rodas e pneus FAW.

Componente principal 4: The Balance Weights (3101060-1104 Series)

The final group in the Conjunto de rodas e pneus FAW is the ‘9.0 Balance weight assembly’ definir (Por exemplo, 3101060-1104, 3101065-1104, 3101085-1104 50G, etc.). The parts list critically marks these as “Sob demanda” ou “**As needed**.”

Este é o “balancing logic” do Conjunto de rodas e pneus 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” e “wobble.” This vibration is not just annoying to the driver; it is destructive, causing “cupped” tire wear and destroying the truck’s kingpins, wheel bearings, and steering components.

Esses “balance weights” are the solution. A technician places the entire Conjunto de rodas e pneus FAW on a “spin balancer,” which identifies the location and mass of the heavy spot. The technician then “counteracts” this by adding these weights (Por exemplo, a ’50G’ or 50-gram weight) to the opposite side of the wheel rim.

O “9.0” designation refers to the 9.00-inch rim, garantindo o “clip-on” weight has the correct profile to securely attach to the rim flange. O “conforme necessário” logic means that every Conjunto de rodas e pneus FAW will require a different combination of these weights to achieve a perfect, smooth, and vibration-free ride.
