Bienvenue dans cette analyse technique critique du Jante en aluminium d'assemblage de moyeu de roue centrale FAW (Partie no. 3104G25DA6T). C'est le complet, high-performance, lightweight wheel-end system for the *centre* (ou “avant”) drive axle of the FAW Jiefang CA4251P66K24T1A3E5 6×4 tracteur semi-remorque diesel.
Le Jante en aluminium d'assemblage de moyeu de roue centrale 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” **Aluminium Rim** 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 driveline technicians and fleet managers. Nous déconstruirons l'ensemble Jante en aluminium d'assemblage de moyeu de roue centrale FAW dans son 13 composants réparables, including the main ‘Hub’ (10045312), the ConMet ‘Bearings’ (Inner and Outer), the ‘Oil seal’ (10080112), and the critical ‘Bearing spacer’ (10045316). Le Jante en aluminium d'assemblage de moyeu de roue centrale FAW is a key component for modern fleet efficiency.
Le coeur du Jante en aluminium d'assemblage de moyeu de roue centrale 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.” Ce “drive hub” is fundamentally different from the “steer hub” sur l'essieu avant.
While both hubs house the bearings, this rear hub has one additional, critical feature: it is internally splined. These splines are designed to engage with the splines of the ‘Half-Shaft’ (axle shaft, voir Assemblée 400). This is how the Jante en aluminium d'assemblage de moyeu de roue centrale FAW receives rotational torque from the differential, which it then transmits to the wheels via the 10 ‘Wheel studs’ (10001400).
Le “Aluminium Rim” designation of the Jante en aluminium d'assemblage de moyeu de roue centrale FAW indicates this hub is designed for use with lightweight, forged aluminum wheels. Ce “logique” is a key performance choice: aluminum rims significantly reduce **unsprung weight** (weight not supported by the suspension). This reduction allows the suspension to react faster, improving tire-to-road contact, increasing ride quality, and reducing wear. They also reduce overall vehicle weight, which can improve fuel economy and increase available payload. This assembly also provides the mounting face for the ‘Rear brake drum’ (3502571-A6T). Le Jante en aluminium d'assemblage de moyeu de roue centrale FAW is built for performance.
Le “logique” de ce spécifique Jante en aluminium d'assemblage de moyeu de roue centrale 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:
In a traditional Jante en aluminium d'assemblage de moyeu de roue centrale 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'assemblage de moyeu de roue centrale FAW. A robust Jante en aluminium d'assemblage de moyeu de roue centrale FAW is key to fleet uptime.
The bearings in the Jante en aluminium d'assemblage de moyeu de roue centrale 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'assemblage de moyeu de roue centrale 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 ‘O-ring’ (3104066-A6T-C00) is also used to ensure the ‘Seal seat’ is locked in place.
Le « Bouchon de remplissage d'huile »’ (10036508) est le “hub cap” ou “bouchon d'huile” that seals the *outer* end of the Jante en aluminium d'assemblage de moyeu de roue centrale 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.” Proper sealing is essential for the Jante en aluminium d'assemblage de moyeu de roue centrale FAW.
Le “logique” de la Jante en aluminium d'assemblage de moyeu de roue centrale 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'assemblage de moyeu de roue centrale FAW.
Le Jante en aluminium d'assemblage de moyeu de roue centrale FAW (3104G25DA6T) est un complet, pre-assembled, and pre-lubricated unit designed for minimal maintenance and maximum on-road life. Its integration of the ConMet pre-set bearing “logique” is a significant step up from older, manually-adjusted wheel hubs. Le Jante en aluminium d'assemblage de moyeu de roue centrale FAW is truly a modern, high-performance component.
