فاو J6P محور العجلة الخلفية: تفكيك 9 الأجزاء المهمة لنقل الطاقة بشكل لا تشوبه شائبة

This is a complete technical guide to the فاو J6P محور العجلة الخلفية (Model 3104011-A6E) لفاو جيفانغ CA3250P66K2L1T1E 6×4 تفريغ الشاحنة. This deconstruction analyzes 9 serviceable component types, from the main hub casting and tapered roller bearings to the high-strength studs and seals.

ال فاو J6P محور العجلة الخلفية is a foundational component of the tandem drive axle system. Unlike a front hub, this is a part of the drive axle, designed to transfer the immense torque from the axle shaft to the dual-wheel assembly. Its primary functions are to support the massive vertical payload, provide a rigid mounting point for the dual wheels and brake drum, and house the bearings that allow this assembly to rotate under power. In a 6×4 تفريغ الشاحنة, ال فاو J6P محور العجلة الخلفية is subjected to extreme torque, shock loads, and contamination. This deconstruction will analyze the core components of the فاو J6P محور العجلة الخلفية, including the bearing sets, the sealing system, and the wheel mounting hardware. A properly serviced فاو J6P محور العجلة الخلفية is essential for drivetrain integrity, bearing life, and braking performance.

جوهر 1: ال “مَركَز & تحمل” منطق (The Rotating Foundation)

This group represents the core rotating mass of the فاو J6P محور العجلة الخلفية. It includes the main hub casting and the critical bearings that support the load and allow rotation on the axle housing.

1. عنصر: ‘Rear wheel hub’ (3104011-أ6ه) – الكمية 4
هذا (شركات 1) is the main body of the فاو J6P محور العجلة الخلفية. It is a massive, single-piece casting made of high-strength ductile iron. It is designed to house the two bearing races, provide a mounting flange for the ‘Rear brake drum’ (شركات 4), and hold the 10 ‘Stud bolts’ (شركات 2) for the dual-wheel assembly. Its structural integrity is paramount for handling the vehicle’s payload.

2. عنصر: ‘Tapered roller bearing’ (3104030-A6E-C00) – الكمية 8 (4 sets)
هذا (شركات 5 & 8) is the set of tapered roller bearings. ال فاو J6P محور العجلة الخلفية uses two of these bearings per side (an inner and an outer bearing). The BOM lists this part number twice, indicating the inner and outer bearings may be the same size or are supplied as a set. Each bearing consists of an outer race pressed into the hub and an inner cone that slides onto the axle housing spindle.

ال Tapered Roller Logic أمر بالغ الأهمية. These bearings are designed to handle both immense radial loads (the vertical weight of the truck and payload) and axial loads (the side-forces from cornering) simultaneously. A properly functioning فاو J6P محور العجلة الخلفية depends entirely on the health and proper pre-load of these bearings.

جوهر 2: ال “Wheel Mounting” منطق (The Dual-Wheel Stud System)

This group of components is responsible for securely fastening the dual road wheels to the فاو J6P محور العجلة الخلفية. The clamping force of this system is critical to safety and torque transfer.

1. عنصر: ‘Stud bolt – rear wheel hub’ (3104051-32ت) – الكمية 40
هذا (شركات 2) عبارة عن مجموعة من 10 high-tensile steel studs (per hub) that are pressed into the back of the فاو J6P محور العجلة الخلفية شفة. These studs are extra-long to pass through the brake drum, the inner wheel, the spacer, and the outer wheel. They are designed to be a tight, press-fit and are only replaced if the threads are damaged.

2. عنصر: ‘Wheel nut assy’ (3103070-32ت) – الكمية 40
هذا (شركات 3) is the main nut that secures the dual-wheel assembly. ال Clamping Force Logic is that as this nut is tightened, it provides the massive clamping force required to hold both wheels and the طبلة الفرامل FAW J6P (شركات 4) securely against the فاو J6P محور العجلة الخلفية. Any loss of torque on these nuts can lead to wheel wobble and catastrophic failure of the فاو J6P محور العجلة الخلفية studs.

جوهر 3: ال “نظام الختم” منطق (Bearing Protection)

This group of components is dedicated to protecting the tapered roller bearings (شركات 5 & 8) from contamination. On a dump truck, this is one of the most important systems, كما فاو J6P محور العجلة الخلفية is constantly exposed to water, الطين, and abrasive dust.

1. عنصر: ‘Rear hub outer oil seal assy (Style drawing)’ (3104055AA0E) – الكمية 4
هذا (شركات 7) is the primary oil seal. This is a complex, pre-assembled cassette seal that is pressed into the back of the فاو J6P محور العجلة الخلفية. It runs on a polished ‘Oil seal seat’ (شركات 6, 3104044AA0E) that is pressed onto the axle housing spindle. This seal is designed to keep the heavy gear oil *inside* the hub to lubricate the bearings.

2. عنصر: ‘O-ring’ (3104066-A6E-C00) – الكمية 4
هذا (شركات 9) is a large O-ring. ال منطق الختم is that this O-ring likely seals the outer axle shaft flange (not pictured) إلى فاو J6P محور العجلة الخلفية. This prevents water and dirt from entering the hub from the outside and prevents oil from leaking out onto the wheels. A failure of this O-ring or the main seal (شركات 7) will lead to a rapid loss of lubrication and complete failure of the فاو J6P محور العجلة الخلفية المحامل.

جوهر 4: ال “Brake Drum” منطق (The Braking Interface)

This component is the friction partner to the فاو J6P محور العجلة الخلفية, responsible for stopping the vehicle.

1. عنصر: ‘Rear brake drum’ (3502571-A0E) – الكمية 4
هذا (شركات 4) is the heavy cast-iron drum that the rear brake shoes press against. It slides over the 10 wheel studs (شركات 2) and is mounted “inboard” التابع فاو J6P محور العجلة الخلفية شفة.

ال Inboard Drum Logic means the فاو J6P محور العجلة الخلفية must be completely removed from the axle spindle (by removing the axle shaft and spindle nuts) in order to service or replace the brake drum. While this is more labor-intensive, it creates a very strong and stable mounting. ال طبلة الفرامل FAW J6P‘s ability to absorb and dissipate heat is critical for the safety of a fully-loaded dump truck.
