Soporte de suspensión atornillado del eje trasero: Deconstruyendo 7 Piezas críticas para una integridad impecable del chasis

This is the technical deconstruction of the Soporte de suspensión atornillado del eje trasero sistema para el FAW Jiefang CA3250P66K2L1T1E 6×4 camión volcado. Esta guía detalla la 7 serviceable component types that form this critical chassis-to-axle link, focusing on the elements that support the rear axle.

El Soporte de suspensión atornillado del eje trasero is a complete system of heavy-gauge steel brackets, cuñas, 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. Entendiendo esto Soporte de suspensión atornillado del eje trasero is key to tandem-axle maintenance.

Centro 1: El “Load-Bearing” Lógica (The Main Spring Trunnion)

This group represents the foundation of the Soporte de suspensión atornillado del eje trasero 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) – Cantidad 2 cada
Estos (compensación 1 & 2) are the main, mirrored assemblies for the left and right sides of the frame. In a tandem setup, this is often called the trunnion bracket. son enormes, fabricated steel components that house the leaf spring’s pivot point. El Bolted Logic es clave: these brackets are bolted *directly* to the truck’s frame rail, allowing for replacement in case of stress fracturing, a key feature of the Soporte de suspensión atornillado del eje trasero.

2. Componente: ‘Hexagon head bolt with pin hole’ (CQ1512095T) – Cantidad 16
Este (compensación 3) es un especializado, high-tensile fastener. The pin hole feature allows for a cotter pin or locking wire, providing a redundant safety mechanism. Este Lógica de sujetadores ensures that even under extreme vibration, the main nuts cannot back off. Estos 16 bolts secure the main trunnion brackets (compensación 1 & 2) to the frame, making them critical to the Soporte de suspensión atornillado del eje trasero‘s safety.

Centro 2: El “Alineación de precisión” Lógica (Positioning Assembly)

This component group ensures the entire tandem bracket system is perfectly aligned on the frame. Misalignment of the Soporte de suspensión atornillado del eje trasero 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) – Cantidad 4
Este (compensación 4) is a precision alignment assembly. El Positioning Pin Logic es simple pero efectivo: pins on this plate lock into pre-drilled holes in the truck frame, acting as dowels. The main spring brackets (compensación 1 & 2) are then located against these pins *before* the bolts (compensación 3) estan apretados.

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 Soporte de suspensión atornillado del eje trasero component both precise and repeatable, which is essential for correct tandem-axle geometry.

Centro 3: El “Torque Control” Lógica (The Reaction Rod Brackets)

This group of components works with the Soporte de suspensión atornillado del eje trasero 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) – Cantidad 1
Este (compensación 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 Soporte de suspensión atornillado del eje trasero‘s function.

2. Componente: ‘Reaction rod upper bracket on mid-bridge assy’ (2919210-65B) – Cantidad 1
Este (compensación 5), listed in the same component diagram, is the corresponding bracket for the *middle* axle. It includes its specific bracket (‘2919211-65B’) y alfileres (‘2919201-A2E’, ‘2919202-A2E’). It is part of the overall tandem system and shares the same mounting logic as the Soporte de suspensión atornillado del eje trasero.

3. Componente: ‘Bolt’ (CQ1502085T) – Cantidad 16
Este (compensación 7) is another set of 16 high-tensile bolts. These fasteners are used to secure the reaction rod brackets (compensación 5 & 6) to the frame crossmembers. el uso de 32 total main bolts (compensación 3 & 7) for this entire Soporte de suspensión atornillado del eje trasero system highlights the immense forces it is designed to handle.
