Колеса и шины FAW в сборе: Деконструкция 4 Группы критических компонентов

Добро пожаловать в это важное техническое руководство по Колеса и шины FAW в сборе (Часть №. 3101010-75С). Это полный, road-contacting assembly for the FAW Jiefang CA4251P66K24T1A3E5 6×4 дизельный полуприцеп тягач. This component is the final link in the powertrain, responsible for supporting the entire vehicle load and providing all traction and braking forces.

The Колеса и шины FAW в сборе is a complete, pre-mounted unit, specified here as a 12R22.5 18-ply radial tyre on a 22.5×9.00 колесо. Его “логика” is to provide a durable, high-load-capacity, and safe connection to the road surface, while also being serviceable for balancing and inflation.

Это подробное руководство является важным ресурсом для профессиональных технических специалистов., менеджеры автопарка, и специалисты по запчастям. Мы разберем всю Колеса и шины FAW в сборе в свой 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.

Основной компонент 1: The Tyre (3106010-15Вт)

The first serviceable component of the Колеса и шины FAW в сборе is the ’12R22.5 18-ply radial tyre’ (3106010-15Вт). Это “логика” 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. “р” stands for **Radial Construction**, which is the modern standard for truck tires. It means the plies run radially (в 90 степени) from bead to bead, providing a flexible sidewall for a smoother ride and lower rolling resistance. “22.5” is the diameter of the wheel (rim) in inches.
• **18-ply:** This is the most critical specification for a heavy-duty Колеса и шины FAW в сборе. “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 (НАПРИМЕР., 120 пси) 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 (а “blowout”) under load.

This is a “tubeless” шина, designed to create an airtight seal directly against the wheel rim, which is a key feature of the modern Колеса и шины FAW в сборе.

Основной компонент 2: The Wheel Rim (3101015А4Е)

The ‘22.5×9.00 wheel rim & hub assembly’ (3101015А4Е) is the structural “скелет” принадлежащий Колеса и шины FAW в сборе. This is the heavy-duty steel (or sometimes forged aluminum) wheel that the tyre is mounted on.

Its size, **22.5×9.00**, имеет решающее значение. The “22.5” inch diameter must exactly match the tyre. The “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 (section)’ (3101021А4Е), which is the outer “hoop,” and the ‘wheel hub/disc’ (3101036А4Е), which is the center disc that bolts to the truck’s axle.

This wheel is a “hub-piloted” дизайн, meaning it is centered on the axle by the large center bore, not by the lug nuts (as in older “stud-piloted” система). This provides a more accurate, vibration-free mounting. A bent or cracked rim is a critical failure of the Колеса и шины FAW в сборе, as it will not hold air and will cause a dangerous wheel “wobble.”

Основной компонент 3: The Valve Stem (3101055А4Е)

The ‘V3.20.12 (Код ETRTO) Tubeless inner tube valve assy for trucks’ (3101055А4Е) is the high-pressure valve stem. This is not the small, резина “snap-in” valve seen on a passenger car. Это тяжелая работа, все металл (brass and steel) “bolt-in” valve assembly.

Его “логика” 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 Колеса и шины FAW в сборе would result in a rapid, if not catastrophic, loss of air pressure, ведущие к “blowout” and a loss of vehicle control. It is a small, but critically important, safety component of the Колеса и шины FAW в сборе.

Основной компонент 4: The Balance Weights (3101060-1104 Series)

The final group in the Колеса и шины FAW в сборе is the ‘9.0 Balance weight assembly’ набор (НАПРИМЕР., 3101060-1104, 3101065-1104, 3101085-1104 50Г, и т. д.). The parts list critically marks these as “по требованию” или “**As needed**.”

Это “balancing logic” принадлежащий Колеса и шины FAW в сборе. 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” и “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.

Эти “balance weights” are the solution. A technician places the entire Колеса и шины FAW в сборе on a “spin balancer,” which identifies the location and mass of the heavy spot. The technician then “counteracts” this by adding these weights (НАПРИМЕР., a ’50G’ or 50-gram weight) to the opposite side of the wheel rim.

The “9.0” designation refers to the 9.00-inch rim, обеспечение “clip-on” weight has the correct profile to securely attach to the rim flange. The “as needed” logic means that every Колеса и шины FAW в сборе will require a different combination of these weights to achieve a perfect, smooth, and vibration-free ride.
