Support de suspension boulonné pour essieu arrière: Déconstruction 7 Pièces critiques pour une intégrité parfaite du châssis

This is the technical deconstruction of the Support de suspension boulonné pour essieu arrière système pour le FAW Jiefang CA3250P66K2L1T1E 6×4 tombereau. Ce guide détaille les 7 serviceable component types that form this critical chassis-to-axle link, focusing on the elements that support the rear axle.

Le Support de suspension boulonné pour essieu arrière is a complete system of heavy-gauge steel brackets, cales, 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. Comprendre cela Support de suspension boulonné pour essieu arrière is key to tandem-axle maintenance.

Cœur 1: Le “Load-Bearing” Logique (The Main Spring Trunnion)

This group represents the foundation of the Support de suspension boulonné pour essieu arrière système. These are the primary components that transfer the vehicle’s load from the frame to the leaf springs shared by the tandem axles.

1. Composant: ‘Rear leaf spring bracket assy’ (2912445-65B & 2912450-65B) – Quantité 2 chaque
Ces (Comp 1 & 2) sont les principaux, 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. Le Bolted Logic est la clé: these brackets are bolted *directly* to the truck’s frame rail, allowing for replacement in case of stress fracturing, une caractéristique clé du Support de suspension boulonné pour essieu arrière.

2. Composant: ‘Hexagon head bolt with pin hole’ (CQ1512095T) – Quantité 16
Ce (Comp 3) est un spécialiste, high-tensile fastener. The pin hole feature allows for a cotter pin or locking wire, providing a redundant safety mechanism. Ce Logique de fixation ensures that even under extreme vibration, the main nuts cannot back off. Ces 16 bolts secure the main trunnion brackets (Comp 1 & 2) to the frame, making them critical to the Support de suspension boulonné pour essieu arrière‘s safety.

Cœur 2: Le “Alignement de précision” Logique (Positioning Assembly)

This component group ensures the entire tandem bracket system is perfectly aligned on the frame. Misalignment of the Support de suspension boulonné pour essieu arrière assembly can lead to poor handling, severe tire wear, and ‘dog tracking’.

1. Composant: ‘Shim and positioning pin assy – rear leaf spring bracket’ (2912405-65B) – Quantité 4
Ce (Comp 4) is a precision alignment assembly. Le 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) sont serrés.

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 Support de suspension boulonné pour essieu arrière component both precise and repeatable, which is essential for correct tandem-axle geometry.

Cœur 3: Le “Torque Control” Logique (The Reaction Rod Brackets)

This group of components works with the Support de suspension boulonné pour essieu arrière 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. Composant: ‘Reaction rod rear upper bracket assy’ (2919220-65B) – Quantité 1
Ce (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 Support de suspension boulonné pour essieu arrièrela fonction.

2. Composant: ‘Reaction rod upper bracket on mid-bridge assy’ (2919210-65B) – Quantité 1
Ce (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 Support de suspension boulonné pour essieu arrière.

3. Composant: 'Boulon’ (CQ1502085T) – Quantité 16
Ce (Comp 7) is another set of 16 boulons à haute résistance. These fasteners are used to secure the reaction rod brackets (Comp 5 & 6) to the frame crossmembers. L'utilisation de 32 total main bolts (Comp 3 & 7) for this entire Support de suspension boulonné pour essieu arrière system highlights the immense forces it is designed to handle.
