Suporte de suspensão aparafusado do eixo traseiro: Desconstruindo 7 Peças críticas para integridade impecável do chassi

This is the technical deconstruction of the Suporte de suspensão aparafusado do eixo traseiro sistema para o FAW Jiefang CA3250P66K2L1T1E 6×4 caminhão despejando. Este guia detalha 7 serviceable component types that form this critical chassis-to-axle link, focusing on the elements that support the rear axle.

O Suporte de suspensão aparafusado do eixo traseiro is a complete system of heavy-gauge steel brackets, calços, and high-tensile fasteners that secures the tandem-axle suspension. This bolted assembly is designed for serviceability, allowing technicians to replace individual brackets that may wear or be damaged. This deconstruction will analyze the main spring trunnion brackets, the specific rear axle reaction rod brackets, and the fastener systems used to maintain the vehicle’s structural integrity. Entendendo isso Suporte de suspensão aparafusado do eixo traseiro is key to tandem-axle maintenance.

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

Este grupo representa a base do Suporte de suspensão aparafusado do eixo traseiro sistema. These are the primary components that transfer the vehicle’s load from the frame to the leaf springs shared by the tandem axles.

1. Componente: ‘Rear leaf spring bracket assy’ (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. In a tandem setup, this is often called the trunnion bracket. They are massive, fabricated steel components that house the leaf spring’s pivot point. O Bolted Logic é a chave: these brackets are bolted *directly* to the truck’s frame rail, allowing for replacement in case of stress fracturing, a key feature of the Suporte de suspensão aparafusado do eixo traseiro.

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, the main nuts cannot back off. Esses 16 bolts secure the main trunnion brackets (Comp. 1 & 2) to the frame, making them critical to the Suporte de suspensão aparafusado do eixo traseiro‘s safety.

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

This component group ensures the entire tandem bracket system is perfectly aligned on the frame. Misalignment of the Suporte de suspensão aparafusado do eixo traseiro assembly can lead to poor handling, severe tire wear, and ‘dog tracking’.

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 do eixo traseiro component 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 do eixo traseiro system to manage axle torque. The reaction rods (or ‘torque rods’) prevent the axles from rotating during acceleration and braking. These brackets are the frame-side anchor points for those rods.

1. Componente: ‘Reaction rod rear upper bracket assy’ (2919220-65B) – Quantidade 1
Esse (Comp. 6) is the key component for the *rear* axle within this assembly. It is a complete bracket assembly (‘2919212-517’) designed specifically to anchor the *rear* axle’s upper reaction rod. It also uses an ‘Elastic dowel pin’ (‘2919201-A2E’) for a tight, vibration-dampening fit. This is a core part of the Suporte de suspensão aparafusado do eixo traseirofunção.

2. Componente: ‘Reaction rod upper bracket on mid-bridge assy’ (2919210-65B) – Quantidade 1
Esse (Comp. 5), listed in the same component diagram, is the corresponding bracket for the *middle* axle. It includes its specific bracket (‘2919211-65B’) and pins (‘2919201-A2E’, ‘2919202-A2E’). It is part of the overall tandem system and shares the same mounting logic as the Suporte de suspensão aparafusado do eixo traseiro.

3. Componente: 'Parafuso’ (CQ1502085T) – Quantidade 16
Esse (Comp. 7) is another set of 16 parafusos de alta resistência. These fasteners are 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 do eixo traseiro system highlights the immense forces it is designed to handle.
