Tambour de frein FAW J6P: Déconstruction 18 Pièces critiques pour une puissance de freinage impeccable

Il s'agit d'un guide technique complet sur le Tambour de frein FAW J6P and its associated front wheel hub assembly (3103010-4E) Pour le FAW Jiefang CA3250P66K2L1T1E 6×4 tombereau. Cette déconstruction analyse 18 serviceable parts that form the entire rotating assembly, which is critical for both braking and load-bearing.

Le Tambour de frein FAW J6P (Partie no. 3501571-4E) est un véhicule robuste, 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 Tambour de frein FAW J6P lui-même, as well as the wheel hub that supports it, the bearings that allow it to rotate, and the seals that protect it. Un service correctement entretenu Tambour de frein FAW J6P and hub assembly is essential for safe, fonctionnement fiable.

Cœur 1: Le “Tambour de freinage” Logique (The Friction Component)

This is the primary component referenced in the Tambour de frein FAW J6P système. C'est le grand, lourd, cast-iron ring that rotates with the wheel.

1. Composant: ‘Front brake drum’ (3501571-4E) – Quantité 2
Ce (Comp 18) est le Tambour de frein FAW J6P lui-même. C'est un énorme, single-piece casting designed to absorb and dissipate the extreme heat generated during braking. Le Friction Surface Logic est critique: its inner diameter is precision-machined to a perfectly round, smooth surface for the brake shoes to press against. Any out-of-roundness, “points chauds,” or cracks in this Tambour de frein FAW J6P will cause severe braking vibration, reduced stopping power, and potential failure.

2. Composant: Matériel de montage (CQ1500816, Q40308) – Quantité 10 chaque
Ce (Comp 12, 13) is the dedicated mounting hardware for the Tambour de frein FAW J6P. This includes ‘Hex head guide bolts’ (Comp 12) et « Rondelles élastiques’ (Comp 13). These small bolts are used to hold the drum onto the ‘Front wheel hub’ (Comp 1) during assembly and service, preventing the heavy drum from falling off when the wheel is removed. Le Tambour de frein FAW J6P is ultimately held in place by the main wheel studs, but these bolts are critical for alignment and service.

Cœur 2: Le “Hub Foundation” Logique (The Rotating Body)

Le Tambour de frein 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. Composant: ‘Front wheel hub’ (3103011-4E) – Quantité 2
Ce (Comp 1) is the main body of the ‘Front wheel hub assy’ (3103010-4E). It is a massive iron casting that houses the bearings and provides the mounting flange for both the Tambour de frein FAW J6P and the road wheel.

2. Composant: « Goujon – front wheel hub’ (3103051-4EB1) – Quantité 20
Ce (Comp 3) est l'ensemble de 10 (pour les moyeux) high-tensile studs that are pressed into the hub. Le Tambour de frein FAW J6P (Comp 18) and the road wheel slide onto these studs.

3. Composant: ‘Wheel nut and washer assy’ (3103070-4E) & ‘Hex thick nut’ (CQ36120T) – Quantité 20 chaque
Ce (Comp 4, 5) is the hardware that holds the wheel onto the hub. Le Logique de force de serrage is that these nuts are tightened to a high torque, sandwiching the Tambour de frein FAW J6P between the wheel and the hub flange. This ensures all three components rotate as a single, unité solide.

Cœur 3: Le “Palier” Logique (The Load-Bearing System)

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

1. Composant: Bearing Assemblies (30314B, 30314UN, 30311) – Quantité 2 chaque (Inner/Outer)
Ce (Comp 6, 7, 8, 9) est l'ensemble de roulements à rouleaux coniques. The assembly uses a large ‘Inner bearing assy’ (Comp 6/7) and a smaller ‘Outer bearing assy’ (Comp 8/9). Each bearing consists of an outer race pressed into the hub and an inner cone that rides on the spindle.

Le Logique du rouleau conique est critique. These bearings are designed to handle both radial loads (vertical weight) et charges axiales (side forces from cornering). The rotational smoothness of the Tambour de frein FAW J6P is entirely dependent on these bearings being properly lubricated and adjusted.

Cœur 4: Le “Scellage & Ajustement” Logique (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 Tambour de frein FAW J6P and hub.

1. Composant: Système d'étanchéité (3103045-4E, 3103066-4E, 3103067-4EA1)
Ce (Comp 2, 10, 11) is the complete sealing solution. The ‘Oil seal assy’ (Comp 2) est un grand, spring-loaded seal pressed into the back of the hub to protect the inner bearing. The ‘Cap – front wheel hub’ (Comp 10) et son 'Joint’ (Comp 11) seal the front of the hub. A failed seal will destroy the bearings, leading to hub failure and a non-functional Tambour de frein FAW J6P.

2. Composant: Bearing Adjustment Group (3001061-367, 3001064-A0S, 3001063-A0S)
Ce (Comp 15, 16, 14) is the spindle nut assembly. Le Logique de précharge des roulements is the most critical service procedure. A technician tightens the ‘Adjustment nut’ (Comp 15) to a specific torque to set the correct “presser” on the bearings. The ‘Lock washer’ (Comp 16) and ‘Lock ring’ (Comp 14) are then used to secure this setting.

3. Composant: ‘Screw and wave washer’ (3001066-A0S) – Quantité 6
Ce (Comp 17) is the final locking mechanism. These screws pass through the lock ring (Comp 14) and into the adjustment nut (Comp 15), providing a redundant, verrouillage positif. This ensures the pre-load setting on the Tambour de frein FAW J6P‘s bearings cannot change during operation, preventing wheel wobble and brake inefficiency.
