Рама FAW J6P: Деконструкция 26 Важные детали для безупречной структурной целостности

This is the definitive technical deconstruction of the Рама FAW J6P для FAW Jiefang CA3250P66K2L1T1E 6×4 самосвал. This guide provides a service-level breakdown of the 26 critical structural components, from the main side members to the complex crossmembers and suspension brackets that form the truck’s backbone.

The Рама FAW J6P is the single most important assembly of the vehicle, acting as the foundation for all other components. Это тяжелая работа, high-tensile steel ladder frame designed to withstand the extreme torsional, bending, and shock loads of a dump truck application. This deconstruction will analyze the main longitudinal beams, the transverse crossmembers that provide rigidity, and the multitude of brackets that attach the engine, такси, и подвеска. A sound, fatigue-free Рама FAW J6P is non-negotiable for vehicle safety, несущая способность, and the alignment of the entire drivetrain.

Основной 1: The “Longitudinal” Логика (The Main Side Members)

This group forms the two main ‘rails’ принадлежащий Рама FAW J6P. These are the primary load-bearing components that run the entire length of the truck.

1. Компонент: ‘Left side member assy’ (2801025А14БЖ) – Кол-во 1
Этот (Комп 1) is the complete left-hand longitudinal beam. Это сингл, C-channel or I-beam profile, precision-drilled to accept all crossmembers, suspension brackets, and the fuel tank. Its uncompromised structural integrity is essential for the fFAW J6P Frame.

2. Компонент: ‘Right side member assy’ (2801030А14БЖ) – Кол-во 1
Этот (Комп 2) is the mirrored right-hand longitudinal beam. Together with the left member, it forms the ‘ladder’ принадлежащий Рама FAW J6P. Any twisting or cracking in these beams constitutes a critical chassis failure.

Основной 2: The “Transverse” Логика (The Crossmembers)

The crossmembers are the transverse beams that bolt or rivet between the two side members. They provide the critical torsional rigidity for the Рама FAW J6P, preventing it from twisting like a pretzel.

1. Компонент: ‘Front crossmember’ (2801072-70ты) – Кол-во 1
Этот (Комп 3) is the front-most crossmember, which supports the bumper and radiator. It is a complex assembly that includes 8 welded square nuts for easy component mounting. It is attached via ‘Front crossmember left/right connecting plate’ (Комп 4, 5) and ‘Reinforcement plate-front crossmember’ (Комп 25). This front assembly is the face of the Рама FAW J6P.

2. Компонент: ‘Rear crossmember – передняя листовая рессора’ (2901092-71минет) – Кол-во 1
Этот (Комп 8) is a specialized crossmember located at the rear mounting point of the front leaf springs. It is a high-stress component that anchors the front suspension. It is supported by four ‘Reinforcement plates’ (Комп 9), highlighting the critical loads it handles for the Рама FAW J6P.

3. Компонент: ‘Third crossmember assy’ (2801110-71А) – Кол-во 2
Этот (Комп 11) is a mid-ship crossmember, often supporting the gearbox and driveshaft carrier bearing. Its position is critical for drivetrain alignment. The Рама FAW J6P uses these to maintain its shape.

4. Компонент: ‘Balance suspension crossmember’ (2801172-95А) – Кол-во 1
Этот (Комп 17) is the main crossmember for the rear tandem-axle suspension. It is a heavy-duty beam that anchors the suspension’s ‘trunnion’ or pivot point. It is connected via ‘Upper/Lower connecting plate’ (Комп 18, 19) and ‘Lower connecting shim’ (Комп 20). This is the load-bearing heart of the rear Рама FAW J6P.

5. Компонент: ‘Rear crossmember assy’ (2801180-487) – Кол-во 1
Этот (Комп 21) is the final crossmember at the very end of the Рама FAW J6P. It provides final rigidity and supports the rear tow hook and taillight assembly. It is connected via ‘Left/Right lower connecting plate’ (Комп 22, 23).

Основной 3: The “Приостановка & Тело” Логика (Монтажные кронштейны)

This group represents the numerous brackets bolted to the Рама FAW J6P that serve as the mounting points for the suspension, такси, and dump body.

1. Компонент: Front Suspension Brackets (Комп 6, 10)
This includes the ‘Front support – передняя листовая рессора’ (Комп 6, 2902441-56А) and the ‘Rear support assy – передняя листовая рессора’ (Комп 10, 2902450-71Б). These two sets of brackets hold the entire front axle and leaf spring assembly. Their position on the Рама FAW J6P is critical for front-end alignment.

2. Компонент: ‘Upper support – передний амортизатор’ (2905411-50А) – Кол-во 2
Этот (Комп 7) is the top mounting point for the front shock absorbers. It is bolted high on the Рама FAW J6P to provide the leverage needed for dampening.

3. Компонент: Rear Suspension Brackets (Комп 16)
This is the ‘Balance suspension pad left bracket assy’ (Комп 16, 2801035-487). These four brackets are the main mounting pads for the rear tandem-axle ‘trunnion’ сборка, working with the ‘Balance suspension crossmember’ (Комп 17) to support the entire rear load. These are some of the highest-stress points on the Рама FAW J6P.

4. Компонент: Тело & Ancillary Brackets (Комп 14, 15, 24, 26)
This group includes ‘Sub-frame connecting gusset assy’ (Комп 14) for the dump body, ‘Truck body connecting plate’ (Комп 15), ‘Pin seat’ (Комп 24) for the cab tilt, and ‘Strap cotter pin assy’ (Комп 26). These smaller brackets are essential for attaching all other vehicle systems to the Рама FAW J6P.
