Алюминиевый обод ступицы переднего колеса FAW в сборе: Критический фокус на 10 Обслуживаемые компоненты

Добро пожаловать в это важное техническое руководство по Алюминиевый обод ступицы переднего колеса FAW в сборе (Часть №. 3103601-91Вт). Это полный, high-performance, lightweight wheel-end system for the front steer axle of the FAW Jiefang CA4251P66K24T1A3E5 6×4 дизельный полуприцеп тягач.

The Алюминиевый обод ступицы переднего колеса FAW в сборе is a sophisticated, non-drive assembly. Его “логика” is to provide a low-friction, high-strength rotating mount for the front wheel, while also housing the ‘Brake drum’ (3501571-54Вт) and the critical ‘ABS ring’ (10037801) 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 переднего колеса FAW в сборе в свой 10 исправные компоненты, including the main ‘Hub’ (10080596), the ‘Outer bearing’ (10041099), the ‘Inner bearing’ (10026058), and the critical ‘Oil seal’ (10080107).

Основной компонент: The ‘Hub’ (10080596) and ‘Rim’

Сердце Алюминиевый обод ступицы переднего колеса FAW в сборе is the ‘Hub’ (10080596). 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’ (10041099) and ‘Inner bearing’ (10026058). Второй, он включает в себя 10 ‘Wheel studs’ (10023593) that the wheel is bolted to. Третий, the ‘Brake drum’ (3501571-54Вт) mounts to its inner face.

The “Aluminium Rim” часть Алюминиевый обод ступицы переднего 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 steering response. They also reduce overall vehicle weight, improving fuel economy. This entire assembly, including the ‘Hub cap assembly’ (3103065AA8S-C00), is the complete rotating mass.

The “Логика”: Подшипниковая система (Внутренний 10026058 & Внешний 10041099)

The “логика” принадлежащий Алюминиевый обод ступицы переднего колеса FAW в сборе is to allow a multi-ton wheel to spin freely with almost zero friction. This is achieved by a “unitized” bearing system from Cummins (康迈). Подробности списка запчастей:

• **’Outer bearing (Cummins)’ (10041099):** The smaller bearing at the outer end of the hub.
• **’Inner bearing (Cummins)’ (10026058):** The larger, main load-bearing bearing at the inner end of the hub.
• **’Bearing spacer (Cummins)’ (10023828):** The critical spacer.

These are **tapered roller bearings**, designed to handle the immense radial (vertical weight) and axial (side-load from cornering) силы. In a traditional Алюминиевый обод ступицы переднего колеса FAW в сборе, these two bearings are “свободный,” and a technician must tighten the ‘Axle head lock nut’ (3001060AA8S-C00) to a precise, low torque to set the “bearing preload.”

Однако, this ConMet (康迈) system is different. The ‘Bearing spacer’ (10023828) is a precision-ground, “matched” spacer. Его “логика” is to create a “unitized” hub. The technician installs the bearings, проставка, and then tightens the ‘Axle head lock nut’ to a very high, fixed torque. The *spacer* absorbs this torque, automatically setting the bearing preload to the perfect factory specification. This eliminates human error, increases service life, and is a key “логика” of the modern Алюминиевый обод ступицы переднего колеса FAW в сборе.

Критическое уплотнение: The ‘Oil Seal’ (10080107)

The bearings in the Алюминиевый обод ступицы переднего колеса FAW в сборе are lubricated by heavy-duty hub oil. The ‘Oil seal (Cummins)’ (10080107) is the single most critical component for keeping this oil *in* and keeping water and dirt *out*.

This is a high-tech, multi-lip radial shaft seal. It is pressed into the back of the ‘Hub’ (10080596), and its flexible, spring-loaded lips ride on a polished “wear ring” on the main axle spindle (from Assembly 510).

A failure of this one seal in the Алюминиевый обод ступицы переднего 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* (НАПРИМЕР., in heavy rain or a puddle), water will contaminate the oil, causing the bearings to rust and “spall” (flake apart), leading to the same failure.

The ‘Hub cap assembly’ (3103065AA8S-C00) seals the *outer* end of the Алюминиевый обод ступицы переднего колеса FAW в сборе. It is a sealed cap with a clear “sight glass,” allowing a technician to visually inspect the oil level and condition without having to disassemble the hub.

The ABS Logic: ‘ABS Ring’ (10037801)

The “логика” принадлежащий Алюминиевый обод ступицы переднего колеса FAW в сборе‘s braking system is contained in the ‘ABS ring (Cummins)’ (10037801). Это “тональное кольцо” для антиблокировочной тормозной системы.

Это “toothed” metal ring that is pressed onto the ‘Hub’ (10080596). Когда колесо вращается, the teeth of this ring fly past the ‘Wheel speed sensor’ (3550360-6С, from Assembly 510). 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 ‘Brake drum’ (3501571-54Вт), 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 переднего колеса FAW в сборе. A cracked or dirt-fouled ring will disable the ABS.
