Алюминиевый обод ступицы заднего колеса FAW в сборе: Критический фокус на 13 Обслуживаемые компоненты

Добро пожаловать в это важное техническое руководство по Алюминиевый обод ступицы заднего колеса FAW в сборе (Часть №. 3104G24DA6T). Это полный, high-performance, lightweight wheel-end system for the *drive axles* of the FAW Jiefang CA4251P66K24T1A3E5 6×4 дизельный полуприцеп тягач.

The Алюминиевый обод ступицы заднего колеса FAW в сборе is a sophisticated, pre-set “unitized” hub. Его “логика” is to provide a low-friction, high-strength rotating mount for the “dual-wheel” setup. This assembly must support the entire dynamic *and* static payload of the trailer, house the ‘Rear brake drum’ (3502571-A6T), and contain the ‘ABS ring’ (10041090) for the anti-lock braking system.

This in-depth guide is an essential resource for professional wheel-end technicians and fleet managers. Мы разберем всю Алюминиевый обод ступицы заднего колеса FAW в сборе в свой 13 исправные компоненты, including the main ‘Hub’ (10045312), the ‘Inner’ and ‘Outer’ подшипники (from ConMet), and the critical ‘Oil seal’ (10080112).

Основной компонент: The ‘Hub’ (10045312) and ‘Rim’

Сердце Алюминиевый обод ступицы заднего колеса FAW в сборе is the ‘Hub’ (10045312). This is the main structural component, массивный, precision-machined casting (often ductile iron) that forms the rotating “wheel-end.” This is *not* the “rim” (the part the tyre mounts to), но “hub” that the rim bolts *onto*.

This ‘Hub’ has several critical functions. Первый, it houses the “races” for the ‘Outer bearing’ (10045483) and ‘Inner bearing’ (10045759). Второй, он включает в себя 10 ‘Wheel studs’ (10001400) that the dual-wheel assembly is bolted to. Третий, the ‘Rear brake drum’ (3502571-A6T) mounts to its inner face, and the ‘ABS ring’ (10041090) is pressed onto it.

The “Aluminium Rim” часть Алюминиевый обод ступицы заднего колеса FAW в сборе refers to the “колесо” сам (как номер детали. 3101015A4E from Assembly 512, which mounts to this hub). Using an aluminum rim instead of steel is a “логика” choice for reducing **unsprung weight**. Lighter wheels respond faster to bumps, improving ride quality and handling. They also reduce overall vehicle weight, improving fuel economy and increasing potential payload. Весь этот Алюминиевый обод ступицы заднего колеса FAW в сборе is the complete rotating mass.

The “Unitized” Bearing Logic (ConMet System)

The “логика” этого конкретного Алюминиевый обод ступицы заднего колеса FAW в сборе lies in its advanced, “unitized” bearing system. The parts are all sourced from ConMet (康迈公司), a leader in hub-end technology. The key components are:

• **’Outer bearing’ (10045483 / 10045313):** The two-part tapered roller bearing at the outer end of the hub.
• **’Inner bearing’ (10045759 / 10045314):** The larger, main load-bearing tapered roller bearing at the inner end of the hub.
• **’Bearing spacer’ (10045316):** The critical component that sets this assembly apart.

In a traditional Алюминиевый обод ступицы заднего колеса FAW в сборе, these two bearings are “loose.” A technician must tighten the main axle nut to a precise, *low-torque* “предварительная загрузка” спецификация, usually while spinning the hub. This process is difficult, time-consuming, and a common source of errors (over-tightening leads to bearing seizure; under-tightening leads to “колебаться” and failure).

This ConMet system’s “логика” is different. The ‘Bearing spacer’ is a precision-ground, “matched” spacer that is engineered to be the *exact* width needed to set the perfect preload. The technician installs the inner bearing, проставка, and the outer bearing. Затем, they simply tighten the main axle nut to a very *high*, fixed torque. The spacer absorbs this torque, automatically setting the bearing preload to the perfect factory specification. This eliminates guesswork, dramatically increases bearing life, and simplifies service for the Алюминиевый обод ступицы заднего колеса FAW в сборе.

Критическое уплотнение: The ‘Oil Seal’ (10080112) and ‘Hub Cap’ (10036508)

The bearings in the Алюминиевый обод ступицы заднего колеса FAW в сборе are lubricated by heavy-duty axle/gear oil. The ‘Oil seal (Cummins)’ (10080112) is the single most critical component for keeping this oil *in* and keeping water, пыль, and road grime *out*.

This is a high-tech, multi-lip radial shaft seal. It is pressed into the back of the ‘Hub’ (10045312), and its flexible, spring-loaded lips ride on the ‘Seal seat’ (3104044-A6T), a polished “wear ring” on the main axle housing.

A failure of this one seal in the Алюминиевый обод ступицы заднего колеса FAW в сборе is a catastrophic event. If it leaks oil *out*, the ‘Inner’ and ‘Outer’ bearings will run dry, overheat, and seize, which can cause the entire wheel to lock up or detach from the vehicle. If it leaks *in*, water will contaminate the oil, causing the bearings to rust and “spall” (flake apart). This is why the ‘Seal retaining ring’ (3104066-A6T-C00) is also used to ensure the seal is locked in place.

«Маслозаливная пробка’ (10036508) это “hub cap” или “масляная заглушка” that seals the *outer* end of the Алюминиевый обод ступицы заднего колеса FAW в сборе. Этот компонент (often with a clear “sight glass”) allows a technician to visually inspect the oil level and condition without having to disassemble the hub, which is a key service “логика.”

The ABS Logic: ‘ABS Ring’ (10041090)

The “логика” принадлежащий Алюминиевый обод ступицы заднего колеса FAW в сборе‘s braking system is contained in the ‘ABS ring (Cummins)’ (10041090). Это “тональное кольцо” для антиблокировочной тормозной системы.

Это “toothed” metal ring that is pressed onto the ‘Hub’ (10045312). Когда колесо вращается, the teeth of this ring fly past the ‘Wheel speed sensor’ (отдельная часть). Этот “chopping” of the magnetic field creates a digital pulse, which is sent to the truck’s ABS computer.

The ABS computer uses this pulse to know the exact rotational speed of the wheel. If the driver “panic brakes” and the computer sees this ring suddenly *stop* (indicating a locked wheel), it will instantly “насос” the ‘Rear brake drum’ (3502571-A6T), allowing the wheel to regain traction. Этот “anti-lock” logic is a critical safety feature, and it is entirely dependent on the integrity of this ‘ABS ring’ в рамках Алюминиевый обод ступицы заднего колеса FAW в сборе.
