Jante en aluminium d'ensemble de moyeu de roue arrière FAW: Un accent critique sur 13 Composants réparables

Bienvenue dans ce guide technique critique sur le Jante en aluminium d'ensemble de moyeu de roue arrière FAW (Partie no. 3104G24DA6T). C'est le complet, high-performance, lightweight wheel-end system for the *drive axles* of the FAW Jiefang CA4251P66K24T1A3E5 6×4 tracteur semi-remorque diesel.

Le Jante en aluminium d'ensemble de moyeu de roue arrière FAW est un sophistiqué, pre-set “unitized” moyeu. C'est “logique” 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. Nous déconstruirons l'ensemble Jante en aluminium d'ensemble de moyeu de roue arrière FAW dans son 13 composants réparables, including the main ‘Hub’ (10045312), the ‘Inner’ and ‘Outer’ roulements (from ConMet), and the critical ‘Oil seal’ (10080112).

Composant principal: The ‘Hub’ (10045312) and ‘Rim’

Le coeur du Jante en aluminium d'ensemble de moyeu de roue arrière FAW is the ‘Hub’ (10045312). C'est le principal élément structurel, un massif, precision-machined casting (often ductile iron) that forms the rotating “wheel-end.” This is *not* the “jante” (the part the tyre mounts to), mais le “moyeu” that the rim bolts *onto*.

This ‘Hub’ has several critical functions. D'abord, it houses the “races” for the ‘Outer bearing’ (10045483) and ‘Inner bearing’ (10045759). Deuxième, il présente le 10 ‘Wheel studs’ (10001400) that the dual-wheel assembly is bolted to. Troisième, the ‘Rear brake drum’ (3502571-A6T) mounts to its inner face, and the ‘ABS ring’ (10041090) is pressed onto it.

Le “Aluminium Rim” une partie du Jante en aluminium d'ensemble de moyeu de roue arrière FAW refers to the “roue” lui-même (comme la référence. 3101015A4E from Assembly 512, which mounts to this hub). Using an aluminum rim instead of steel is a “logique” 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. Tout cela Jante en aluminium d'ensemble de moyeu de roue arrière FAW is the complete rotating mass.

Le “Unitized” Logique des roulements (ConMet System)

Le “logique” de ce spécifique Jante en aluminium d'ensemble de moyeu de roue arrière FAW 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 Jante en aluminium d'ensemble de moyeu de roue arrière FAW, these two bearings are “loose.” A technician must tighten the main axle nut to a precise, *low-torque* “précharger” spécification, 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 “osciller” and failure).

This ConMet system’s “logique” 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. Alors, 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 Jante en aluminium d'ensemble de moyeu de roue arrière FAW.

Étanchéité critique: The ‘Oil Seal’ (10080112) and ‘Hub Cap’ (10036508)

The bearings in the Jante en aluminium d'ensemble de moyeu de roue arrière FAW are lubricated by heavy-duty axle/gear oil. Le 'Joint d'huile (Cummins)’ (10080112) is the single most critical component for keeping this oil *in* and keeping water, poussière, 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 Jante en aluminium d'ensemble de moyeu de roue arrière FAW is a catastrophic event. If it leaks oil *out*, the ‘Inner’ and ‘Outer’ bearings will run dry, surchauffer, 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.

The ‘Oil filler plug’ (10036508) est le “hub cap” ou “bouchon d'huile” that seals the *outer* end of the Jante en aluminium d'ensemble de moyeu de roue arrière FAW. Ce composant (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 “logique.”

The ABS Logic: ‘ABS Ring’ (10041090)

Le “logique” de la Jante en aluminium d'ensemble de moyeu de roue arrière FAW‘s braking system is contained in the ‘ABS ring (Cummins)’ (10041090). C'est le “anneau de tonalité” pour le système de freinage antiblocage.

C'est un “toothed” metal ring that is pressed onto the ‘Hub’ (10045312). Pendant que la roue tourne, the teeth of this ring fly past the ‘Wheel speed sensor’ (une partie séparée). Ce “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 “pompe” the ‘Rear brake drum’ (3502571-A6T), allowing the wheel to regain traction. Ce “antiblocage” logic is a critical safety feature, and it is entirely dependent on the integrity of this ‘ABS ring’ au sein de Jante en aluminium d'ensemble de moyeu de roue arrière FAW.
