Jante en aluminium d'assemblage de moyeu de roue avant FAW: Un accent critique sur 10 Composants réparables

Bienvenue dans ce guide technique critique sur le Jante en aluminium d'assemblage de moyeu de roue avant FAW (Partie no. 3103601-91W). C'est le complet, high-performance, lightweight wheel-end system for the front steer axle of the FAW Jiefang CA4251P66K24T1A3E5 6×4 tracteur semi-remorque diesel.

Le Jante en aluminium d'assemblage de moyeu de roue avant FAW est un sophistiqué, non-drive assembly. C'est “logique” is to provide a low-friction, high-strength rotating mount for the front wheel, while also housing the ‘Brake drum’ (3501571-54W) 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. Nous déconstruirons l'ensemble Jante en aluminium d'assemblage de moyeu de roue avant FAW dans son 10 composants réparables, including the main ‘Hub’ (10080596), the ‘Outer bearing’ (10041099), the ‘Inner bearing’ (10026058), and the critical ‘Oil seal’ (10080107).

Composant principal: The ‘Hub’ (10080596) and ‘Rim’

Le coeur du Jante en aluminium d'assemblage de moyeu de roue avant FAW is the ‘Hub’ (10080596). This is the main structural component, a massive, precision-machined casting (often ductile iron) that forms the rotating “wheel-end.” This is *not* the “rim” (the part the tyre mounts to), but the “moyeu” that the rim bolts *onto*.

This ‘Hub’ has several critical functions. D'abord, it houses the “races” for the ‘Outer bearing’ (10041099) and ‘Inner bearing’ (10026058). Deuxième, il présente le 10 ‘Wheel studs’ (10023593) that the wheel is bolted to. Troisième, the ‘Brake drum’ (3501571-54W) mounts to its inner face.

Le “Aluminium Rim” une partie du Jante en aluminium d'assemblage de moyeu de roue avant FAW refers to the “roue” lui-même (like Part No. 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 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.

Le “Logique”: Bearing System (Inner 10026058 & Outer 10041099)

Le “logique” de la Jante en aluminium d'assemblage de moyeu de roue avant FAW 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). The parts list details:

• **’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) forces. In a traditional Jante en aluminium d'assemblage de moyeu de roue avant FAW, these two bearings are “lâche,” and a technician must tighten the ‘Axle head lock nut’ (3001060AA8S-C00) to a precise, low torque to set the “bearing preload.”

Cependant, this ConMet (康迈) system is different. The ‘Bearing spacer’ (10023828) is a precision-ground, “matched” spacer. C'est “logique” is to create a “unitized” moyeu. The technician installs the bearings, the spacer, 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 “logique” of the modern Jante en aluminium d'assemblage de moyeu de roue avant FAW.

Critical Sealing: The ‘Oil Seal’ (10080107)

The bearings in the Jante en aluminium d'assemblage de moyeu de roue avant FAW 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 (de l'Assemblée 510).

A failure of this one seal in the Jante en aluminium d'assemblage de moyeu de roue avant 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* (Par exemple, 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 Jante en aluminium d'assemblage de moyeu de roue avant FAW. 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)

Le “logique” de la Jante en aluminium d'assemblage de moyeu de roue avant FAW‘s braking system is contained in the ‘ABS ring (Cummins)’ (10037801). C'est le “anneau de tonalité” for the Anti-lock Braking System.

C'est un “toothed” metal ring that is pressed onto the ‘Hub’ (10080596). As the wheel rotates, the teeth of this ring fly past the ‘Wheel speed sensor’ (3550360-6S, de l'Assemblée 510). 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 ‘Brake drum’ (3501571-54W), allowing the wheel to regain traction. Ce “anti-lock” 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 avant FAW. A cracked or dirt-fouled ring will disable the ABS.
