Ступица переднего колеса FAW J6P: Деконструкция 18 Важнейшие детали для безупречного вращения

Это полная техническая деконструкция. Ступица переднего колеса FAW J6P (Model 3103010-4E) для FAW Jiefang CA3250P66K2L1T1E 6×4 самосвал. В этом руководстве подробно описаны 18 типы обслуживаемых компонентов, from the hub casting and tapered roller bearings to the spindle adjustment nuts and seals.

The Ступица переднего колеса FAW J6P является критическим, high-stress assembly that forms the rotating foundation for the front steer axle. Its primary functions are to support the entire vertical load of the truck’s front end, provide a rigid mounting point for the wheel and the brake drum, and rotate freely on the steering knuckle spindle with minimal friction. В большегрузном самосвале, а Ступица переднего колеса FAW J6P must be over-engineered to withstand constant high-g impacts from rough terrain and the immense braking forces required to stop a fully-loaded vehicle. This deconstruction will analyze the core components of the Ступица переднего колеса FAW J6P, including the bearing sets, the sealing system, and the wheel mounting hardware. A properly serviced Ступица переднего колеса FAW J6P is essential for steering safety, bearing life, and braking performance.

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

This group represents the core rotating mass of the Ступица переднего колеса FAW J6P. It includes the main hub casting and the critical bearings that support the load.

1. Компонент: ‘Front wheel hub’ (3103011-4Э) – Кол-во 2
Этот (Комп 1) is the main body of the Ступица переднего колеса FAW J6P. It is a massive, single-piece casting made of high-strength iron or steel. It is designed to house the two bearing races, provide a mounting flange for the brake drum (Комп 18), and hold the 10 ‘Stud bolts’ (Комп 3) for the wheel. Its structural integrity is non-negotiable.

2. Компонент: Bearing Assemblies (30314Б, 30314А, 30311) – Кол-во 2 каждый (Inner/Outer)
Этот (Комп 6 & 7) is the set of tapered roller bearings. The Ступица переднего колеса FAW J6P uses two of these bearings per side: a large ‘Inner bearing assy’ (Комп 6/7) and a smaller outer bearing (Комп 9). Each bearing consists of an ‘Outer race’ (Комп 6-1/7-1) pressed into the hub and an ‘Inner cone assy’ (Комп 6-2/7-2) that slides onto the spindle.

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

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

This group of components is responsible for securely fastening the road wheel to the Ступица переднего колеса FAW J6P. The clamping force of this system is critical to safety.

1. Компонент: ‘Stud bolt – front wheel hub’ (3103051-4ЕВ1) – Кол-во 20
Этот (Комп 3) представляет собой набор 10 high-tensile steel studs (per hub) that are pressed into the back of the Ступица переднего колеса FAW J6P фланец. These studs are what the wheel slides onto. They are designed to be a tight, press-fit and are only replaced if the threads are damaged or the stud is broken.

2. Компонент: ‘Wheel nut and washer assy’ (3103070-4Э) – Кол-во 20
Этот (Комп 4) is the main nut that secures the wheel. It’s an assembly that includes a captive, conical washer. The Логика зажимного усилия is that as the nut is tightened, the washer spins freely, preventing the nut from galling the surface of the aluminum or steel wheel. This allows for a much higher and more accurate torque specification, ensuring the wheel is perfectly centered and secured to the Ступица переднего колеса FAW J6P.

3. Компонент: ‘Hex thick nut’ (CQ36120T) – Кол-во 20
Этот (Комп 5) is listed as a ‘Hex thick nut’. This is often used in a dual-wheel setup, but in this Ступица переднего колеса FAW J6P context, it may be a “варенье ореховое” or part of a two-piece nut system, providing a redundant locking mechanism to prevent the main wheel nut from backing off.

Основной 3: The “Уплотнение & Pre-load” Логика (Spindle Hardware)

This group of components seals the Ступица переднего колеса FAW J6P and provides the critical mechanism for setting the bearing pre-load.

1. Компонент: Система уплотнения (3103045-4Э, 3103066-4Э, 3103067-4EA1)
Этот (Комп 2, 10, 11) is the complete sealing solution. The ‘Oil seal assy’ (Комп 2) is a large, spring-loaded seal pressed into the *back* of the Ступица переднего колеса FAW J6P to keep grease in and water/dirt out. The ‘Cap – front wheel hub’ (Комп 10) and its ‘Gasket’ (Комп 11) seal the *front* of the hub. A failure in this system will lead to rapid bearing destruction.

2. Компонент: Bearing Adjustment Group (3001061-367, 3001064-А0С, 3001063-А0С)
Этот (Комп 15, 16, 14) is the spindle nut assembly. The Bearing Pre-load Logic is the most critical service procedure for the Ступица переднего колеса FAW J6P. A technician tightens the ‘Adjustment nut’ (Комп 15) to a specific torque to set the correct “squeeze” on the bearings. The ‘Lock washer’ (Комп 16) is then bent into a groove on the nut, and the ‘Lock ring’ (Комп 14) slides over it.

3. Компонент: ‘Screw and wave washer’ (3001066-А0С) – Кол-во 6
Этот (Комп 17) is the final locking mechanism. These screws pass through the lock ring (Комп 14) and into the adjustment nut (Комп 15), providing a redundant, positive lock. This ensures the pre-load setting on the Ступица переднего колеса FAW J6P cannot change during operation.

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

This component is not part of the Ступица переднего колеса FAW J6P сам, but is a critical partner, as it mounts directly to it.

1. Компонент: ‘Front brake drum’ (3501571-4Э) – Кол-во 2
Этот (Комп 18) is the heavy cast-iron drum that the brake shoes press against to stop the truck. It slides over the 10 wheel studs (Комп 3) and is sandwiched between the Ступица переднего колеса FAW J6P flange and the road wheel.

2. Компонент: ‘Hex head guide bolt’ (CQ1500816) & «Пружинная шайба’ (Q40308) – Кол-во 10 каждый
Этот (Комп 12, 13) is the hardware for the brake drum. The Drum Mounting Logic is that these small bolts and washers are used to hold the brake drum (Комп 18) onto the Ступица переднего колеса FAW J6P *before* the wheel is installed. This prevents the heavy drum from falling off during a tire change and makes wheel mounting easier. The primary clamping force is provided by the main wheel nuts.
