التجميع المنطقي لتركيب ناقل الحركة FAW: نظرة نقدية على 4 مكونات الدعم الرئيسية

مرحبًا بك في هذا الدليل الفني المهم حول التجميع المنطقي لتركيب ناقل الحركة FAW. هذا هو الكامل, heavy-duty rear support system for the manual transmission, designed specifically for the FAW Jiefang CA4251P66K24T1A3E5 6×4 جرار نصف مقطورة ديزل. This system is the structural “مهد” that supports the entire weight of the gearbox and isolates it from the chassis.

ال التجميع المنطقي لتركيب ناقل الحركة FAW is not the transmission itself, but rather the set of “غادر” (1706051A91W) و “يمين” (1706052A91W) brackets that bolt to the rear of the gearbox. These brackets then rest on the chassis crossmember (انظر الجمعية 323), providing a flexible, vibration-damped connection.

This in-depth guide is an essential resource for professional chassis technicians, مديري الأسطول, ومتخصصين في قطع الغيار. سنقوم بتفكيك الكل التجميع المنطقي لتركيب ناقل الحركة FAW فيه 4 مكونات صالحة للخدمة, explaining the function of each bracket and the critical, high-tensile flange bolts used to secure them against the immense torque and vibration of a heavy-duty powertrain.

المكونات الأساسية: غادر (1706051A91W) & يمين (1706052A91W) بين قوسين

قلب ال التجميع المنطقي لتركيب ناقل الحركة FAW consists of a symmetrical pair of heavy-duty support brackets:

• **’Transmission mounting left bracket’ (1706051A91W):** This is the main support arm for the left-hand side of the gearbox.
• **’Transmission mounting right bracket’ (1706052A91W):** This is the symmetrical counterpart for the right-hand side.

هذه ليست بسيطة “ل” بين قوسين. They are massive, complex castings, typically made from high-strength ductile iron or fabricated steel. They are heavily ribbed and gusseted to provide maximum rigidity against “torque-twist.” Their primary function is to act as the “feet” من انتقال العدوى. They bolt directly to the sides of the transmission’s rear housing (the auxiliary “المربع الفرعي”).

ال “منطق” من هذا التجميع المنطقي لتركيب ناقل الحركة FAW is to provide a wide, منصة مستقرة. الشقة, lower surfaces of these brackets are what rest on top of the ‘Transmission mounting flexible cushion assy’ (the large rubber mounts, detailed in Assembly 323). هذا “bracket-on-cushion” design is what isolates the powertrain from the chassis, which is the entire purpose of a modern التجميع المنطقي لتركيب ناقل الحركة FAW.

A crack or failure in one of these brackets is a catastrophic structural failure. It would cause the entire rear of the transmission to “sag” or drop. This would immediately misalign the entire driveline, changing the driveshaft’s “U-joint angles,” which would cause severe vibration, and eventual failure of the U-joints, center support bearing, or the transmission’s output shaft bearing. سلامة هذا التجميع المنطقي لتركيب ناقل الحركة FAW is therefore critical to the entire driveline.

نظام السحابة: Heavy-Duty Flange Bolts

The final two components of the التجميع المنطقي لتركيب ناقل الحركة FAW are the high-tensile fasteners that secure the brackets to the transmission housing. A mount is only as strong as its bolts.

The parts list calls for two different bolt sizes, المجموع 10 البراغي:

• **’Hex head flange bolt’ (Q1851650T):** 6 وحدات.
• **’Hex head flange bolt’ (Q1851670T):** 4 وحدات.

هذه ليست الأجهزة القياسية. ال “شفة” الرأس عبارة عن غسالة متكاملة. This is a critical design choice for mounting a steel bracket to an (often) aluminum transmission housing. The wide flange distributes the immense clamping force over a larger surface area, preventing the hard steel bolt from “حفر في” أو “تكسير” the softer aluminum casing.

ال “ت” suffix on these bolts (على سبيل المثال, Q1851650**T**) indicates a specific high-tensile strength class (على سبيل المثال, 10.9) and a specialized, طلاء مقاوم للتآكل. These bolts must endure the constant, multi-axis “قص” forces from the engine’s torque. The different part numbers (-1650T vs -1670T) indicate different lengths, which are required for the different thicknesses of the transmission casing’s mounting bosses.

Using the correct, factory-specified, high-tensile flange bolts is the only way to ensure the التجميع المنطقي لتركيب ناقل الحركة FAW remains securely attached to the gearbox. A loose or failed bolt would cause the entire transmission to become unsupported, مما يؤدي إلى فشل ذريع. ال التجميع المنطقي لتركيب ناقل الحركة FAW relies on this hardware.
