منتصف الجسر انسحب قوس التعليق: تفكيك 7 الأجزاء المهمة لسلامة الهيكل الخالية من العيوب

This is the technical deconstruction of the منتصف الجسر انسحب قوس التعليق لفاو جيفانغ CA3250P66K2L1T1E 6×4 تفريغ الشاحنة. هذا الدليل تفاصيل 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.

ال منتصف الجسر انسحب قوس التعليق is not a single part but a complete system of heavy-gauge steel brackets, الحشوات, 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. فهم هذا منتصف الجسر انسحب قوس التعليق is key to tandem-axle maintenance.

جوهر 1: ال “الحاملة” منطق (The Main Spring Brackets)

تمثل هذه المجموعة الأساس منتصف الجسر انسحب قوس التعليق. These are the primary components that transfer the vehicle’s load from the frame to the leaf springs of the middle axle.

1. عنصر: ‘Rear leaf spring bracket assy – mid’ (2912445-65ب & 2912450-65ب) – الكمية 2 كل
هؤلاء (شركات 1 & 2) are the main, 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. ال Bolted Logic هو المفتاح: these brackets are bolted *directly* to the truck’s frame rail using high-strength fasteners (شركات 3), allowing for replacement in case of stress fracturing. They are the primary load-transfer point for the منتصف الجسر انسحب قوس التعليق نظام.

2. عنصر: ‘Hexagon head bolt with pin hole’ (CQ1512095T) – الكمية 16
هذا (شركات 3) هو متخصص, high-tensile fastener. The pin hole feature allows for a cotter pin or locking wire, providing a redundant safety mechanism. هذا المنطق السحابي ensures that even under extreme vibration and torsional flex, the main nuts cannot back off. هؤلاء 16 bolts are responsible for securing the main spring brackets (شركات 1 & 2) to the frame, making them critical to the منتصف الجسر انسحب قوس التعليق‘s safety.

جوهر 2: ال “محاذاة الدقة” منطق (Positioning Assembly)

This small but vital component group ensures the main spring brackets are perfectly aligned on the frame. Misalignment of the منتصف الجسر انسحب قوس التعليق can lead to poor handling, severe tire wear, and ‘dog tracking’ of the tandem axles.

1. عنصر: ‘Shim and positioning pin assy – rear leaf spring bracket’ (2912405-65ب) – الكمية 4
هذا (شركات 4) is a precision alignment assembly. ال 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 (شركات 1 & 2) are then located against these pins *before* the bolts (شركات 3) يتم تشديدها.

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 منتصف الجسر انسحب قوس التعليق both precise and repeatable, which is essential for correct tandem-axle geometry.

جوهر 3: ال “Torque Control” منطق (The Reaction Rod Brackets)

This group of components works with the منتصف الجسر انسحب قوس التعليق 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. عنصر: ‘Reaction rod upper bracket on mid-bridge assy’ (2919210-65ب) – الكمية 1
هذا (شركات 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’). ال Elastic Pin Logic يضمن ضيق, vibration-dampening fit, preventing the bracket from shifting or rattling under load.

2. عنصر: ‘Reaction rod rear upper bracket assy’ (2919220-65ب) – الكمية 1
هذا (شركات 6) is a similar assembly, but designed for the *rear* axle’s upper reaction rod, mounted near the منتصف الجسر انسحب قوس التعليق. 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. عنصر: "بولت."’ (CQ1502085T) – الكمية 16
هذا (شركات 7) is another set of 16 مسامير عالية الشد. These are likely used to secure the reaction rod brackets (شركات 5 & 6) to the frame crossmembers. استخدام 32 total main bolts (شركات 3 & 7) for this entire منتصف الجسر انسحب قوس التعليق system highlights the immense forces it is designed to handle. Failure of these fasteners would lead to a loss of axle control.
