Suporte de suspensão aparafusado de ponte intermediária: Desconstruindo 7 Peças críticas para integridade impecável do chassi

This is the technical deconstruction of the Suporte de suspensão aparafusado de ponte intermediária para o FAW Jiefang CA3250P66K2L1T1E 6×4 caminhão despejando. Este guia detalha 7 serviceable component types that form this critical chassis-to-axle link. This assembly is responsible for securing the leaf springs and reaction rods to the vehicle’s frame.

O Suporte de suspensão aparafusado de ponte intermediária is not a single part but a complete system of heavy-gauge steel brackets, calços, and high-tensile fasteners. Unlike welded components, this bolted assembly is designed for serviceability, allowing technicians to replace individual brackets or hardware that may wear or be damaged from extreme off-road use. This deconstruction will analyze the main spring brackets, the reaction rod brackets, and the specific fastener systems used to maintain the vehicle’s structural integrity under millions of load cycles. Entendendo isso Suporte de suspensão aparafusado de ponte intermediária is key to tandem-axle maintenance.

Essencial 1: O “Rolamento de carga” Lógica (The Main Spring Brackets)

Este grupo representa a base do Suporte de suspensão aparafusado de ponte intermediária. These are the primary components that transfer the vehicle’s load from the frame to the leaf springs of the middle axle.

1. Componente: ‘Rear leaf spring bracket assy – mid’ (2912445-65B & 2912450-65B) – Quantidade 2 cada
Esses (Comp. 1 & 2) são os principais, mirrored assemblies for the left and right sides of the frame. They are massive, fabricated steel brackets designed to house the leaf spring’s mounting pin. O Bolted Logic é a chave: these brackets are bolted *directly* to the truck’s frame rail using high-strength fasteners (Comp. 3), allowing for replacement in case of stress fracturing. They are the primary load-transfer point for the Suporte de suspensão aparafusado de ponte intermediária sistema.

2. Componente: ‘Hexagon head bolt with pin hole’ (CQ1512095T) – Quantidade 16
Esse (Comp. 3) is a specialized, high-tensile fastener. The pin hole feature allows for a cotter pin or locking wire, providing a redundant safety mechanism. Esse Lógica do Fixador ensures that even under extreme vibration and torsional flex, the main nuts cannot back off. Esses 16 bolts are responsible for securing the main spring brackets (Comp. 1 & 2) to the frame, making them critical to the Suporte de suspensão aparafusado de ponte intermediária‘s safety.

Essencial 2: O “Alinhamento de precisão” Lógica (Positioning Assembly)

This small but vital component group ensures the main spring brackets are perfectly aligned on the frame. Misalignment of the Suporte de suspensão aparafusado de ponte intermediária can lead to poor handling, severe tire wear, and ‘dog tracking’ of the tandem axles.

1. Componente: ‘Shim and positioning pin assy – rear leaf spring bracket’ (2912405-65B) – Quantidade 4
Esse (Comp. 4) is a precision alignment assembly. O Positioning Pin Logic is simple but effective: pins on this plate lock into pre-drilled holes in the truck frame, acting as dowels. The main spring brackets (Comp. 1 & 2) are then located against these pins *before* the bolts (Comp. 3) are tightened.

The ‘shim’ aspect of this assembly is also critical. It allows for fine-tuning the bracket’s position to compensate for minor variations in the frame. This part makes the installation of a new Suporte de suspensão aparafusado de ponte intermediária both precise and repeatable, which is essential for correct tandem-axle geometry.

Essencial 3: O “Torque Control” Lógica (The Reaction Rod Brackets)

This group of components works with the Suporte de suspensão aparafusado de ponte intermediária system to manage axle torque. The reaction rods (or ‘torque rods’) prevent the axle from rotating during acceleration and braking. These brackets are the frame-side anchor points for those rods.

1. Componente: ‘Reaction rod upper bracket on mid-bridge assy’ (2919210-65B) – Quantidade 1
Esse (Comp. 5) is the complete assembly for the *middle* axle’s upper reaction rod. It includes the main bracket (‘2919211-65B’) and ‘Elastic dowel pins’ (‘2919201-A2E’, ‘2919202-A2E’). O Elastic Pin Logic ensures a tight, vibration-dampening fit, preventing the bracket from shifting or rattling under load.

2. Componente: ‘Reaction rod rear upper bracket assy’ (2919220-65B) – Quantidade 1
Esse (Comp. 6) is a similar assembly, but designed for the *rear* axle’s upper reaction rod, mounted near the Suporte de suspensão aparafusado de ponte intermediária. It also includes its specific bracket (‘2919212-517’) and pin. This illustrates how this system integrates suspension points for *both* axles in the tandem setup.

3. Componente: 'Parafuso’ (CQ1502085T) – Quantidade 16
Esse (Comp. 7) is another set of 16 parafusos de alta resistência. These are likely used to secure the reaction rod brackets (Comp. 5 & 6) to the frame crossmembers. O uso de 32 total main bolts (Comp. 3 & 7) for this entire Suporte de suspensão aparafusado de ponte intermediária system highlights the immense forces it is designed to handle. Failure of these fasteners would lead to a loss of axle control.
