Ступица заднего колеса FAW Logic в сборе, стальное колесо: The 13 Критические компоненты внутри

Добро пожаловать в это важное техническое руководство по Ступица заднего колеса FAW Logic в сборе, стальное колесо (Часть №. 3104G24DA6T). Это полный, load-bearing “wheel-end” system for the rear *drive axles* of the FAW Jiefang CA4251P66K24T1A3E5 6×4 дизельный полуприцеп тягач. This assembly is the final link in transmitting torque to the road.

The Ступица заднего колеса FAW Logic в сборе, стальное колесо является а “unitized” hub designed for a heavy-duty drive axle. Его “логика” is to provide a low-friction, high-strength rotating mount for the “dual-wheel” **Steel Wheel** setup, while also being internally splined to accept the half-shaft (axle shaft) from the differential.

This in-depth guide is an essential resource for professional driveline technicians and fleet managers. Мы разберем всю Ступица заднего колеса FAW Logic в сборе, стальное колесо в свой 13 исправные компоненты, including the main ‘Hub’ (10045312), the ConMet ‘Bearings’ (Inner and Outer), the ‘Rear brake drum’ (3502571-A6T), and the critical ‘ABS ring’ (10041090).

Основной компонент: The ‘Hub’ (10045312) – Drive vs. Steer

Сердце Ступица заднего колеса FAW Logic в сборе, стальное колесо is the ‘Hub’ (10045312). This is the main structural component, a massive, precision-machined casting of ductile iron. Этот “drive hub” is fundamentally different from the “steer hub” on the front axle.

While both hubs house the bearings, this rear hub has one additional, критическая особенность: it is internally splined. These splines are designed to engage with the splines of the ‘Half-Shaft’ (axle shaft, see Assembly 328 или 400). This is how the Ступица заднего колеса FAW Logic в сборе, стальное колесо receives rotational torque from the differential, which it then transmits to the wheels via the 10 ‘Wheel studs’ (10001399).

The “Steel Wheel” designation of the Ступица заднего колеса FAW Logic в сборе, стальное колесо indicates this hub is designed for the high-clamping-force and durability requirements of steel dual-wheels (“duallies”), which are the standard for maximum load capacity on a drive axle. This assembly also provides the mounting face for the ‘Rear brake drum’ (3502571-A6T).

The “Unitized” Bearing Logic (ConMet System)

The “логика” of this specific Ступица заднего колеса FAW Logic в сборе, стальное колесо 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 Ступица заднего колеса FAW Logic в сборе, стальное колесо, these two bearings are “loose.” A technician must tighten the main axle nut to a precise, *low-torque* “preload” 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, the spacer, and the outer bearing. Then, 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 Ступица заднего колеса FAW Logic в сборе, стальное колесо.

Critical Sealing: The ‘Oil Seal’ (10080112) and ‘Hub Cap’ (10036508)

The bearings in the Ступица заднего колеса FAW Logic в сборе, стальное колесо 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 Ступица заднего колеса FAW Logic в сборе, стальное колесо 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 ‘O-ring’ (3104066-A6T-C00) is also used to ensure the ‘Seal seat’ is locked in place.

The ‘Oil filler plug’ (10036508) это “hub cap” или “масляная заглушка” that seals the *outer* end of the Ступица заднего колеса FAW Logic в сборе, стальное колесо. 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 Ступица заднего колеса FAW Logic в сборе, стальное колесо‘s braking system is contained in the ‘ABS ring (Cummins)’ (10041090). Это “tone ring” for the Anti-lock Braking System.

This is a “toothed” metal ring that is pressed onto the ‘Hub’ (10045312). As the wheel rotates, 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 “pump” 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 Ступица заднего колеса FAW Logic в сборе, стальное колесо.
