Ступица заднего колеса FAW J6P: Деконструкция 9 Важные детали для безупречной передачи энергии

Это полное техническое руководство по Ступица заднего колеса FAW J6P (Model 3104011-A6E) для FAW Jiefang CA3250P66K2L1T1E 6×4 самосвал. This deconstruction analyzes 9 типы обслуживаемых компонентов, from the main hub casting and tapered roller bearings to the high-strength studs and seals.

The Ступица заднего колеса FAW J6P 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 самосвал, а Ступица заднего колеса FAW J6P is subjected to extreme torque, shock loads, and contamination. This deconstruction will analyze the core components of the Ступица заднего колеса FAW J6P, including the bearing sets, the sealing system, and the wheel mounting hardware. A properly serviced Ступица заднего колеса FAW J6P is essential for drivetrain integrity, bearing life, and braking performance.

Основной 1: The “Центр & Несущий” Логика (The Rotating Foundation)

This group represents the core rotating mass of the Ступица заднего колеса FAW J6P. It includes the main hub casting and the critical bearings that support the load and allow rotation on the axle housing.

1. Компонент: ‘Rear wheel hub’ (3104011-А6Е) – Кол-во 4
Этот (Комп 1) is the main body of the Ступица заднего колеса FAW J6P. 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’ (Комп 4), and hold the 10 ‘Stud bolts’ (Комп 2) for the dual-wheel assembly. Its structural integrity is paramount for handling the vehicle’s payload.

2. Компонент: ‘Tapered roller bearing’ (3104030-A6E-C00) – Кол-во 8 (4 наборы)
Этот (Комп 5 & 8) is the set of tapered roller bearings. The Ступица заднего колеса FAW J6P 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.

The Tapered Roller Logic имеет решающее значение. These bearings are designed to handle both immense radial loads (the vertical weight of the truck and payload) и осевые нагрузки (the side-forces from cornering) одновременно. Правильно функционирующий Ступица заднего колеса FAW J6P depends entirely on the health and proper pre-load of these bearings.

Основной 2: The “Wheel Mounting” Логика (The Dual-Wheel Stud System)

This group of components is responsible for securely fastening the dual road wheels to the Ступица заднего колеса FAW J6P. The clamping force of this system is critical to safety and torque transfer.

1. Компонент: ‘Stud bolt – rear wheel hub’ (3104051-32Т) – Кол-во 40
Этот (Комп 2) представляет собой набор 10 high-tensile steel studs (per hub) that are pressed into the back of the Ступица заднего колеса FAW J6P фланец. 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. Компонент: ‘Wheel nut assy’ (3103070-32Т) – Кол-во 40
Этот (Комп 3) is the main nut that secures the dual-wheel assembly. The Логика зажимного усилия is that as this nut is tightened, it provides the massive clamping force required to hold both wheels and the Тормозной барабан FAW J6P (Комп 4) securely against the Ступица заднего колеса FAW J6P. Any loss of torque on these nuts can lead to wheel wobble and catastrophic failure of the Ступица заднего колеса FAW J6P studs.

Основной 3: The “Система уплотнения” Логика (Bearing Protection)

This group of components is dedicated to protecting the tapered roller bearings (Комп 5 & 8) from contamination. On a dump truck, this is one of the most important systems, как Ступица заднего колеса FAW J6P is constantly exposed to water, грязь, and abrasive dust.

1. Компонент: ‘Rear hub outer oil seal assy (Стиль рисования)’ (3104055АА0Е) – Кол-во 4
Этот (Комп 7) is the primary oil seal. This is a complex, pre-assembled cassette seal that is pressed into the back of the Ступица заднего колеса FAW J6P. It runs on a polished ‘Oil seal seat’ (Комп 6, 3104044АА0Е) 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. Компонент: ‘O-ring’ (3104066-A6E-C00) – Кол-во 4
Этот (Комп 9) is a large O-ring. The Логика уплотнения is that this O-ring likely seals the outer axle shaft flange (not pictured) к Ступица заднего колеса FAW J6P. 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 (Комп 7) will lead to a rapid loss of lubrication and complete failure of the Ступица заднего колеса FAW J6P подшипники.

Основной 4: The “Brake Drum” Логика (The Braking Interface)

This component is the friction partner to the Ступица заднего колеса FAW J6P, responsible for stopping the vehicle.

1. Компонент: ‘Rear brake drum’ (3502571-А0Е) – Кол-во 4
Этот (Комп 4) is the heavy cast-iron drum that the rear brake shoes press against. It slides over the 10 wheel studs (Комп 2) and is mounted “inboard” принадлежащий Ступица заднего колеса FAW J6P фланец.

The Inboard Drum Logic means the Ступица заднего колеса FAW J6P 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. The Тормозной барабан FAW J6P‘s ability to absorb and dissipate heat is critical for the safety of a fully-loaded dump truck.
