Тормозной барабан FAW J6P: Деконструкция 18 Важные детали для безупречного торможения

Это полное техническое руководство по Тормозной барабан FAW J6P and its associated front wheel hub assembly (3103010-4Э) для FAW Jiefang CA3250P66K2L1T1E 6×4 самосвал. Эта деконструкция анализирует 18 serviceable parts that form the entire rotating assembly, which is critical for both braking and load-bearing.

The Тормозной барабан FAW J6P (Часть №. 3501571-4Э) это сверхмощный, cast-iron component that provides the primary friction surface for the front axle’s braking system. In a fully-loaded dump truck, its ability to absorb and dissipate immense heat is critical for vehicle safety. This component does not work in isolation; it is a key part of the entire front wheel hub assembly. This deconstruction will analyze the Тормозной барабан FAW J6P сам, as well as the wheel hub that supports it, the bearings that allow it to rotate, and the seals that protect it. A properly serviced Тормозной барабан FAW J6P and hub assembly is essential for safe, reliable operation.

Основной 1: The “Brake Drum” Логика (The Friction Component)

This is the primary component referenced in the Тормозной барабан FAW J6P система. Это большой, тяжелый, cast-iron ring that rotates with the wheel.

1. Компонент: ‘Front brake drum’ (3501571-4Э) – Кол-во 2
Этот (Комп 18) это Тормозной барабан FAW J6P сам. It is a massive, single-piece casting designed to absorb and dissipate the extreme heat generated during braking. The Friction Surface Logic имеет решающее значение: its inner diameter is precision-machined to a perfectly round, smooth surface for the brake shoes to press against. Any out-of-roundness, “hot spots,” or cracks in this Тормозной барабан FAW J6P will cause severe braking vibration, reduced stopping power, and potential failure.

2. Компонент: Монтажное оборудование (CQ1500816, Q40308) – Кол-во 10 каждый
Этот (Комп 12, 13) is the dedicated mounting hardware for the Тормозной барабан FAW J6P. This includes ‘Hex head guide bolts’ (Комп 12) и «Пружинные шайбы’ (Комп 13). These small bolts are used to hold the drum onto the ‘Front wheel hub’ (Комп 1) during assembly and service, preventing the heavy drum from falling off when the wheel is removed. The Тормозной барабан FAW J6P is ultimately held in place by the main wheel studs, but these bolts are critical for alignment and service.

Основной 2: The “Hub Foundation” Логика (The Rotating Body)

The Тормозной барабан FAW J6P cannot function without being rigidly mounted to the wheel hub. This group of components forms the rotating foundation that the drum and wheel are bolted to.

1. Компонент: ‘Front wheel hub’ (3103011-4Э) – Кол-во 2
Этот (Комп 1) is the main body of the ‘Front wheel hub assy’ (3103010-4Э). It is a massive iron casting that houses the bearings and provides the mounting flange for both the Тормозной барабан FAW J6P and the road wheel.

2. Компонент: ‘Stud bolt – front wheel hub’ (3103051-4ЕВ1) – Кол-во 20
Этот (Комп 3) это набор 10 (per hub) high-tensile studs that are pressed into the hub. The Тормозной барабан FAW J6P (Комп 18) and the road wheel slide onto these studs.

3. Компонент: ‘Wheel nut and washer assy’ (3103070-4Э) & ‘Hex thick nut’ (CQ36120T) – Кол-во 20 каждый
Этот (Комп 4, 5) is the hardware that holds the wheel onto the hub. The Логика зажимного усилия is that these nuts are tightened to a high torque, sandwiching the Тормозной барабан FAW J6P between the wheel and the hub flange. This ensures all three components rotate as a single, solid unit.

Основной 3: The “Несущий” Логика (The Load-Bearing System)

This group of components allows the Тормозной барабан FAW J6P and hub assembly to rotate freely on the stationary axle spindle, while supporting the entire front-end load.

1. Компонент: Bearing Assemblies (30314Б, 30314А, 30311) – Кол-во 2 каждый (Inner/Outer)
Этот (Комп 6, 7, 8, 9) is the set of tapered roller bearings. The assembly uses a large ‘Inner bearing assy’ (Комп 6/7) and a smaller ‘Outer bearing assy’ (Комп 8/9). Each bearing consists of an outer race pressed into the hub and an inner cone that rides on the spindle.

The Tapered Roller Logic имеет решающее значение. These bearings are designed to handle both radial loads (vertical weight) и осевые нагрузки (side forces from cornering). The rotational smoothness of the Тормозной барабан FAW J6P is entirely dependent on these bearings being properly lubricated and adjusted.

Основной 4: The “Уплотнение & Adjustment” Логика (Spindle Hardware)

This group contains the components that seal the hub assembly and provide the critical mechanism for setting the bearing pre-load, which is essential for the life of the Тормозной барабан FAW J6P and hub.

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 hub to protect the inner bearing. The ‘Cap – front wheel hub’ (Комп 10) and its ‘Gasket’ (Комп 11) seal the front of the hub. A failed seal will destroy the bearings, leading to hub failure and a non-functional Тормозной барабан FAW J6P.

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. 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) and ‘Lock ring’ (Комп 14) are then used to secure this setting.

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 Тормозной барабан FAW J6P‘s bearings cannot change during operation, preventing wheel wobble and brake inefficiency.
