Cubo da roda traseira FAW J6P: Desconstruindo 9 Peças críticas para transferência de energia perfeita

Este é um guia técnico completo para o Cubo da roda traseira FAW J6P (Model 3104011-A6E) para o FAW Jiefang CA3250P66K2L1T1E 6×4 caminhão despejando. This deconstruction analyzes 9 tipos de componentes utilizáveis, from the main hub casting and tapered roller bearings to the high-strength studs and seals.

O Cubo da roda traseira 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 caminhão despejando, o Cubo da roda traseira FAW J6P is subjected to extreme torque, shock loads, and contamination. Esta desconstrução analisará os componentes centrais do Cubo da roda traseira FAW J6P, including the bearing sets, the sealing system, and the wheel mounting hardware. Um atendimento adequado Cubo da roda traseira FAW J6P is essential for drivetrain integrity, bearing life, and braking performance.

Essencial 1: O “Eixo & Consequência” Lógica (The Rotating Foundation)

This group represents the core rotating mass of the Cubo da roda traseira FAW J6P. It includes the main hub casting and the critical bearings that support the load and allow rotation on the axle housing.

1. Componente: ‘Rear wheel hub’ (3104011-A6E) – Quantidade 4
Esse (Comp. 1) é o corpo principal do Cubo da roda traseira FAW J6P. É um enorme, 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’ (Comp. 4), and hold the 10 ‘Stud bolts’ (Comp. 2) for the dual-wheel assembly. Its structural integrity is paramount for handling the vehicle’s payload.

2. Componente: ‘Tapered roller bearing’ (3104030-A6E-C00) – Quantidade 8 (4 sets)
Esse (Comp. 5 & 8) é o conjunto de rolamentos de rolos cônicos. O Cubo da roda traseira 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.

O Lógica de rolo cônico é crítico. These bearings are designed to handle both immense radial loads (the vertical weight of the truck and payload) e cargas axiais (the side-forces from cornering) simultaneously. Um funcionamento adequado Cubo da roda traseira FAW J6P depends entirely on the health and proper pre-load of these bearings.

Essencial 2: O “Montagem de roda” Lógica (The Dual-Wheel Stud System)

This group of components is responsible for securely fastening the dual road wheels to the Cubo da roda traseira FAW J6P. The clamping force of this system is critical to safety and torque transfer.

1. Componente: 'Parafuso – rear wheel hub’ (3104051-32T) – Quantidade 40
Esse (Comp. 2) é um conjunto de 10 high-tensile steel studs (para hubs) that are pressed into the back of the Cubo da roda traseira FAW J6P mesa. These studs are extra-long to pass through the brake drum, the inner wheel, o espaçador, and the outer wheel. They are designed to be a tight, press-fit and are only replaced if the threads are damaged.

2. Componente: ‘Wheel nut assy’ (3103070-32T) – Quantidade 40
Esse (Comp. 3) is the main nut that secures the dual-wheel assembly. O Lógica da Força de Fixação is that as this nut is tightened, it provides the massive clamping force required to hold both wheels and the Tambor de freio FAW J6P (Comp. 4) securely against the Cubo da roda traseira FAW J6P. Any loss of torque on these nuts can lead to wheel wobble and catastrophic failure of the Cubo da roda traseira FAW J6P pregos.

Essencial 3: O “Sistema de vedação” Lógica (Bearing Protection)

This group of components is dedicated to protecting the tapered roller bearings (Comp. 5 & 8) from contamination. On a dump truck, this is one of the most important systems, como o Cubo da roda traseira FAW J6P is constantly exposed to water, lama, and abrasive dust.

1. Componente: ‘Rear hub outer oil seal assy (Style drawing)’ (3104055AA0E) – Quantidade 4
Esse (Comp. 7) is the primary oil seal. Este é um complexo, pre-assembled cassette seal that is pressed into the back of the Cubo da roda traseira FAW J6P. It runs on a polished ‘Oil seal seat’ (Comp. 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. Componente: ‘Anel de vedação’ (3104066-A6E-C00) – Quantidade 4
Esse (Comp. 9) is a large O-ring. O Lógica de Selagem is that this O-ring likely seals the outer axle shaft flange (não retratado) para o Cubo da roda traseira 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 (Comp. 7) will lead to a rapid loss of lubrication and complete failure of the Cubo da roda traseira FAW J6P rolamentos.

Essencial 4: O “Tambor de freio” Lógica (The Braking Interface)

This component is the friction partner to the Cubo da roda traseira FAW J6P, responsible for stopping the vehicle.

1. Componente: ‘Rear brake drum’ (3502571-A0E) – Quantidade 4
Esse (Comp. 4) is the heavy cast-iron drum that the rear brake shoes press against. It slides over the 10 wheel studs (Comp. 2) and is mounted “inboard” do Cubo da roda traseira FAW J6P mesa.

O Inboard Drum Logic means the Cubo da roda traseira 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. O Tambor de freio FAW J6P‘s ability to absorb and dissipate heat is critical for the safety of a fully-loaded dump truck.
