This is an in-depth technical deconstruction of the Задняя подвеска FAW J6P система для FAW Jiefang CA3250P66K2L1T1E 6×4 самосвал. This comprehensive guide details the 45 исправные компоненты, from the robust multi-leaf spring packs to the complex balance beams and anti-roll limiters that ensure stability under extreme loads.

The Задняя подвеска FAW J6P is an extremely robust, multi-leaf spring and balance beam system, engineered for the demanding loads and harsh terrain typically encountered by a 6×4 самосвал. Its primary purpose is to evenly distribute the massive payload across the tandem rear axles, provide reliable traction, and absorb severe impacts, all while maintaining vehicle stability. This advanced design ensures minimal stress on the chassis and maximizes the operational lifespan of the vehicle. A well-maintained Задняя подвеска FAW J6P is paramount for safety, load capacity, и комфорт водителя, making its components critical for sustained performance. We will analyze the main leaf spring assemblies, the complex balance beam system, and the crucial limiting and damping components. Each element of the Задняя подвеска FAW J6P contributes to the overall stability and performance of the vehicle.

Основной 1: The “Многостворчатый” Логика (The Main Spring Packs)

This section covers the primary load-bearing components of the Задняя подвеска FAW J6P – the leaf spring assemblies. These robust packs are designed to manage the substantial weight of the dump body and its contents.

1. Компонент: ‘Rear leaf spring assy’ (2912010-483Дж) – Кол-во 2
Этот (Комп 4) is the complete rear leaf spring assembly. Two of these are used, one per side, to support the rear of the truck. Each assembly is comprised of multiple individual leaves (from ‘2912201-483J’ to ‘2912212-483J’). The Multi-Leaf Logic provides a progressive spring rate, becoming stiffer as the load increases. Это важно для Задняя подвеска FAW J6P to provide a stable ride both empty and fully laden.

2. Компонент: ‘Center bolt – Задняя листовая пружина’ (2912161-483) – Кол-во 2
Этот (Комп 5, part of 4) is the critical bolt that holds the entire leaf spring pack together, ensuring all individual leaves are correctly aligned. This bolt also serves as the locator pin, fitting into the axle pad to prevent the axle from shifting. The integrity of this bolt is vital for the entire Задняя подвеска FAW J6P система.

3. Компонент: «Зажимы’ & ‘Spacers’ (2912135-483Дж, 2912136-483, 2912171-03)
Эта группа (all part of Comp 4) includes the ‘Clamp’ assemblies and ‘Spacers’ that bind the leaves together. These clamps (НАПРИМЕР., ‘Clamp – rear leaf spring 11th leaf’) prevent the individual leaves from fanning out or separating, which would cause the pack to lose its structural integrity. These are crucial for the long-term durability of the Задняя подвеска FAW J6P.

Основной 2: The “Монтаж оси” Логика (U-Bolt System)

This group of components securely fastens the leaf springs to the axles. The clamping force generated by this system is all that holds the tandem axles in place, making it one of the most critical parts of the Задняя подвеска FAW J6P.

1. Компонент: 'U-образный болт – Задняя листовая пружина’ (2912411-71Б) – Кол-во 4
Эти (Комп 2) are the primary fasteners. Четыре таких прочных U-образных болта (по два с каждой стороны) loop under the axle housing and pass up through the cover plate. These must be torqued to an exact specification.

2. Компонент: ‘Nut – для U-образного болта’ (2912413-260) – Кол-во 8
Этот (Комп 1) is the high-strength nut designed to secure the U-bolts. These are often ‘tall’ nuts to ensure maximum thread engagement and clamping force, which is essential for the Задняя подвеска FAW J6P.

3. Компонент: «Крышка – Задняя листовая пружина’ (2912406X487) – Кол-во 2
Этот (Комп 3) is a thick steel plate positioned above the leaf spring. The Логика зажимного усилия is that this plate distributes the load from the U-bolt nuts evenly across the spring pack, preventing the nuts from crushing the spring and ensuring a rigid connection. Весь Задняя подвеска FAW J6P‘s alignment depends on this.

4. Компонент: ‘Rear leaf spring soft pad’ (2912434-65Б) – Кол-во 4
Этот (Комп 42) is a soft pad, likely made of high-density rubber or polyurethane. It sits between the leaf spring pack and the axle housing. Its purpose is to absorb high-frequency vibrations and prevent metal-on-metal contact, reducing noise and shock transfer to the Рама FAW J6P.

Основной 3: The “Balance Beam” Логика (Tandem Articulation)

This complex system is the heart of the tandem-axle Задняя подвеска FAW J6P. It allows the two rear axles to articulate, keeping all eight rear tires in contact with uneven ground for maximum traction and stability.

1. Компонент: ‘Balance beam & balance beam support assy’ (2918010-96AJ) – Кол-во 2
Этот (Комп 34) является основным “trunnion” сборка. It is the large cast or fabricated beam that pivots on a central point mounted to the frame. The leaf springs (Комп 4) connect to the ends of this beam, not directly to the frame. Этот Tandem Axle Logic allows one axle to rise while the other falls, “ходьба” over obstacles.

2. Компонент: ‘Bush – balance beam support pad’ (2918042-260) – Кол-во 2
Эти (Комп 12) are massive, high-density rubber bushings that are pressed into the balance beam support. The entire load of the rear of the truck pivots on these two bushings. They must absorb immense loads and vibrations, making them a critical wear item in the Задняя подвеска FAW J6P.

3. Компонент: «Пад – balance beam support’ (2918072-626) & 'Втулка’ (2918017-626 / 2918041А260)
Этот (Комп 6, 7, 10) is the set of pads and bushings that form the upper and lower covers of the trunnion assembly, creating a serviceable, greaseable pivot point for the Задняя подвеска FAW J6P.

Основной 4: The “Reaction & Limit” Логика (Stability Control)

This final group includes the reaction rods (torque rods) and limiters that control axle positioning. They prevent the axles from moving fore/aft during acceleration and braking and limit extreme suspension travel.

1. Компонент: ‘Anti-roll rod with rubber bushing assy’ (2919005B71B, 2919015B71B, и т. д.) – Кол-во 6
Этот (Комп 19, 20, 24, 25) это набор “reaction rods”. The Torque Rod Logic is to prevent the axles from rotating (axle wrap). These rods form a geometric link between the axle and the Рама FAW J6P, absorbing the braking and acceleration torque. This is a key part of the Задняя подвеска FAW J6P.

2. Компонент: ‘Limit support – буфер’ (2912437-69С) – Кол-во 4
Эти (Комп 43) являются “bump stops”. They are essential safety components that prevent the suspension from over-compressing, which would cause the frame to impact the axle. This protects the Задняя подвеска FAW J6P components and the frame from catastrophic damage during a hard impact.

3. Компонент: ‘Left/Right lateral limit plate’ (2912437-90минет, 2912438-90минет) – Кол-во 1 каждый
Эти (Комп 44, 45) plates are designed to prevent excessive lateral (из стороны в сторону) movement of the axles. This is crucial for maintaining vehicle stability, especially during cornering or when on a side slope with a heavy load. They directly contribute to the stability of the Задняя подвеска FAW J6P.
