عجلة فاو J6P: تفكيك 17 الأجزاء المهمة لعملية حمل الحمولة التي لا تشوبها شائبة

هذا هو التفكيك الفني الكامل لل عجلة فاو J6P and tire assemblies for the FAW Jiefang CA3250P66K2L1T1E 6×4 تفريغ الشاحنة. هذا الدليل تفاصيل 17 serviceable component types, covering two main variants of the عجلة فاو J6P: ال 8.8-20 heavy-duty model and the 8.5-20 standard model.

ال عجلة فاو J6P assembly is the foundational component for transferring all vehicle power, braking forces, and load to the ground. For a heavy-duty dump truck, this is not a simple part; it is a multi-piece, high-strength steel assembly designed to withstand extreme impacts, massive payloads, and high torque from the planetary hubs. This deconstruction will analyze the two primary types of عجلة فاو J6P assemblies found on this vehicle: ال 8.8-20 Heavy-Duty version (3101015AJ6P) و 8.5-20 standard version (3101015-93دبليو). We will also break down the common tire, tube, and flap components (12.00R20 18PR) that are critical to the function of every عجلة فاو J6P. Understanding the differences between these serviceable assemblies is essential for correct parts ordering and safe vehicle operation. A properly maintained عجلة فاو J6P is a non-negotiable for chassis and drivetrain health.

جوهر 1: ال “الشقوق” منطق (3101010AJ6P Assembly)

This group represents the primary heavy-duty عجلة فاو J6P حَشد (الكمية 8), designed for maximum load capacity and durability in severe off-road conditions. This is the main assembly used for the tandem drive axles.

1. عنصر: ‘8.8-20 Heavy-duty wheel rim & disc assy’ (3101015AJ6P) – الكمية 8
هذا (شركات 1) is the core of the heavy-duty عجلة فاو J6P. ال 8.8-20 designation indicates a wider, thicker steel rim designed to handle the 12.00R20 18PR tire under extreme payloads. This is a single, welded assembly combining the outer rim (where the tire sits) and the inner disc (which bolts to the hub). ال “AJ6P” part number signifies its specific, reinforced design for this J6P dump truck, differentiating it from a standard عجلة فاو J6P.

2. عنصر: ‘Elastic lock ring-8.50-20 wheel’ (3101027-J6P) – الكمية 8
هذا (شركات 5) is the specific ‘J6P’ model lock ring for this عجلة فاو J6P. هذا Multi-Piece Rim Logic is standard for heavy-duty trucks. This split steel ring is what locks the tire bead onto the rim. It allows for tire mounting and dismounting in the field with heavy tire irons, which is impossible with a one-piece tubeless rim of this size. This is a critical safety component of the عجلة فاو J6P and must be inspected for wear, الصدأ, or deformation at every tire change, as a failed ring can lead to an explosive disassembly.

جوهر 2: ال “معيار” منطق (3101010-93WJ Assembly)

This group represents the standard عجلة فاو J6P حَشد (الكمية 3), which may be used for the front steer axle or as the spare. It has a slightly different construction, being fully deconstructed in the BOM.

1. عنصر: ‘8.5-20 Wheel rim & disc assy’ (3101015-93دبليو) – الكمية 3
هذا (شركات 1, right table) is the standard 8.5-20 عجلة فاو J6P حَشد. This component is broken down further into its constituent, serviceable parts, unlike the heavy-duty model. The ‘8.5-20’ indicates a standard 8.5-inch width, slightly narrower than the 8.8-inch heavy-duty model.

2. عنصر: ‘Rim body-8.5-20 wheel’ (3101021-93دبليو) – الكمية 3
هذا (شركات 1 sub-part) is the outer rim hoop itself. This is the part that holds the tire, tube, flap, and lock ring (شركات 5, 3101027-174). This part is serviceable and can be replaced if it becomes bent or cracked.

3. عنصر: ‘Wheel disc-8.5-20 wheel’ (3101036-93دبليو) – الكمية 3
هذا (شركات 1 sub-part) is the ‘disc’ or center plate of the عجلة فاو J6P. This is the component with the 10 bolt holes that mounts to the hub. ال Two-Piece Logic here shows that the rim body (شركات 2) and the disc (شركات 3) are manufactured separately and then welded or riveted together to create the final wheel (شركات 1). This is a common manufacturing process for a عجلة فاو J6P, allowing different disc offsets to be paired with a standard rim.

جوهر 3: ال “إطار العجلة & Tube” منطق (The Common Components)

This group of components is common to both types of عجلة فاو J6P التجميعات. This is the ‘tube-type’ setup required for heavy-duty, multi-piece rims, as they are not airtight.

1. عنصر: ‘Outer tire-12.00R20 18PR’ (3106010A174) – الكمية 11 (المجموع)
هذا (شركات 2 غادر, شركات 2 يمين) is the main tire. ال 12.00R20 designation means it is 12 inches wide for a 20-inch rim, with a Radial construction. ال 18العلاقات العامة (18-ply rating) signifies an extremely strong, high-load-capacity tire, essential for a dump truck. This is the literal footprint of the عجلة فاو J6P.

2. عنصر: ‘Inner tube-12.00R20 18PR’ – الكمية 11 (المجموع)
هذا (شركات 3 غادر, شركات 3 يمين) is the inflatable inner tube that holds the compressed air. As this is not a tubeless rim, the tube is a mandatory component for every عجلة فاو J6P. ذات جودة عالية, heavy-duty tube is required to match the 18-ply rating of the outer tire.

3. عنصر: ‘Flap-12.00R20 18PR’ – الكمية 11 (المجموع)
هذا (شركات 4 غادر, شركات 4 يمين) is a thick rubber ‘flap’ or ‘liner’ that sits inside the rim. ال Tube Protection Logic أمر بالغ الأهمية. This flap protects the inner tube from being chafed or punctured by the steel rim (شركات 1) and the lock ring (شركات 5/5). A missing or damaged flap will cause rapid tube failure in the عجلة فاو J6P.

4. عنصر: ‘8.5-20 Valve stem’ (3101016-174) – الكمية 3
هذا (شركات 1 sub-part) is the air valve. It is a serviceable part that attaches to the inner tube and passes through the rim, allowing for inflation. This is a common failure point for the عجلة فاو J6P, as it can be damaged by rocks or debris.

جوهر 4: ال “Dynamic Balancing” منطق (The Balance Weights)

This final group is essential for a smooth, stable ride at speed. An unbalanced عجلة فاو J6P assembly will cause severe vibration, damaging suspension components and causing premature tire wear.

1. عنصر: ‘Wheel balance weight assy’ (3101050-174, إلخ.) – Qty As Req.
هذا (شركات 6 غادر, شركات 6 يمين) is a set of ‘As Required’ weights. The BOM lists multiple variants (3101055, 3101060, 3101065, 3101070) which correspond to different gram-weights (على سبيل المثال, 50g, 100g, 150g).

ال منطق التوازن is that after a tire is mounted, كامل عجلة فاو J6P assembly is placed on a dynamic balancing machine. The machine identifies ‘heavy spots’. A technician then clips these lead or steel weights onto the opposite side of the rim flange to counteract the imbalance. This is a critical final step in servicing any عجلة فاو J6P. Given the size and weight of a 12.00R20 tire, significant weight may be required to properly balance the عجلة فاو J6P حَشد.
