مجموعة التعليق الخلفي FAW للكابينة: السر المكون من 4 أجزاء للحصول على نعومة, رحلة آمنة

مرحبًا بكم في هذا التحليل الفني المتعمق للسعر مجموعة التعليق الخلفي FAW للكابينة. This set of components is one of the most critical structural groups on the FAW Jiefang CA4251P66K24T1A3E5 6×4 جرار نصف مقطورة ديزل. This is not just a simple mounting point; it is a highly-engineered “منطق” حَشد. جوهرها “منطق” is to simultaneously perform two high-stress jobs: it serves as the rear anchor for the entire cab suspension system *and* the rear fixed mount for the chassis’s front leaf springs.

ال مجموعة التعليق الخلفي FAW للكابينة is the primary load-bearing interface connecting the driver’s cab to the truck’s chassis frame. The components detailed here (الجزء لا. 5001280ب91دبليو) are responsible for handling massive longitudinal forces from the chassis suspension *and* vertical forces from the cab suspension (both air spring and coil spring types). This dual-function “منطق” is a masterpiece of engineering, saving weight and frame space.

This expert guide is an essential resource for chassis technicians, مديري الأسطول, ومتخصصين في قطع الغيار. سنقوم بتفكيك الكل مجموعة التعليق الخلفي FAW للكابينة فيه 4 أنواع المكونات الأساسية. سنقوم بتحليل “المنطق المزدوج” of the main structural bracket, and then break down the two different, high-tensile fastener groups that are critical for its safety and integrity.

جامعة ولاية ميشيغان 1: The Dual-Logic “Combined Bracket” (5001280ب91دبليو)

هذا المكون هو “لفترة أطول” and most substantial part of the مجموعة التعليق الخلفي FAW للكابينة. The ‘Cab rear suspension & front steel plate spring rear fixed combined bracket assy’ (5001280ب91دبليو) هو MSU الهيكلي الأساسي. قائمة الأجزاء تدعو إلى اثنين (2), one for the left and one for the right chassis rail.

ال “منطق” من هذا “Combined Bracket” is its brilliant, space-saving, dual-function design. It performs two jobs that would normally require two separate, heavy brackets.

وظيفة 1 منطق: Chassis Spring Mount

The first function is to serve as the *rear fixed mount* for the *chassis’s front leaf spring*. The front of the leaf spring attaches to a shackle that pivots. The rear of that same spring must attach to a fixed, non-moving point on the frame. This bracket is that point.

This means the bracket must be incredibly strong, as it handles all the longitudinal (fore-and-aft) forces of the front axle. All acceleration and braking forces from the front wheels are transferred through the leaf spring and into the chassis *through this single bracket*. This is why it is fabricated from heavy-gauge, فولاذ عالي الشد, designed to resist immense shearing and torsional stress.

وظيفة 2 منطق: Cab Suspension Mount

The second function of the مجموعة التعليق الخلفي FAW للكابينة is to serve as the primary mounting point for the *cab’s rear suspension*. This is the point where the rear cab air spring or coil-over-shock assembly mounts.

This part of the bracket’s “منطق” is to handle the vertical (up-and-down) loads of the cab, isolating the driver’s environment from the chassis. By combining these two functions into one part, FAW engineers saved weight, reduced complexity, and saved valuable space on the chassis rail, all while increasing the overall rigidity of the frame at that junction.

إمكانية الخدمة (جامعة ولاية ميشيغان):

هذا “Combined Bracket” is a primary MSU. It is a non-repairable, safety-critical component. Failures are rare, but can be caused by severe collision damage or (if fasteners are loose) fatigue cracking from vibration. A damaged bracket must be replaced immediately, as a failure here would compromise both the chassis and cab suspension, leading to a loss of vehicle control.

جوهر 2: المنطق السحابي – The Flange Bolt & Nut System (وحدات التخزين المتنقلة 2, 3, 4)

The remaining three component types make up the critical fastening system for the مجموعة التعليق الخلفي FAW للكابينة. This is not a simple collection of hardware; it is a precisely engineered “منطق” system designed for clamping force and vibration resistance.

The system consists of 18 bolts and 18 nuts in total. This indicates a 9-bolt mounting pattern for *each* of the two main brackets.

• جامعة ولاية ميشيغان 2: "مسمار شفة مسدس."’ (Q1851685T) – الكمية: 10
• جامعة ولاية ميشيغان 3: "مسمار شفة مسدس."’ (Q1851695T) – الكمية: 8
• جامعة ولاية ميشيغان 4: "جوز شفة مسدس."’ (Q039716) – الكمية: 18

هذا 1:1 ratio of 18 البراغي ل 18 nuts confirms that these are through-bolt connections, passing completely through the chassis frame rail.

Deconstructing the Fastener “منطق”

ال “منطق” of this system is in the details.

Why Two Different Bolts (جامعة ولاية ميشيغان 2 & 3)?

ال مجموعة التعليق الخلفي FAW للكابينة uses two different part numbers for its bolts (Q1851685T and Q1851695T). ال “منطق” here is simple: different grip lengths. ال 10 bolts of the first type are likely for attaching the main body of the bracket to the flat web of the chassis frame. ال 8 bolts of the second type are likely for the part of the bracket that mounts the spring eye, which may be thicker or require a different length bolt.

All of these are “شفة” البراغي. The flange is an integrated washer. هذا “منطق” distributes the clamping force over a wider area, preventing the bolt head from damaging the bracket. It also makes assembly faster.

ال “شفة الجوز” منطق (جامعة ولاية ميشيغان 4)

The ‘Hexagon flange nut’ (Q039716) is the most critical piece. هؤلاء 18 nuts are also “ذات حواف,” acting as a built-in washer on the nut side. والأهم من ذلك, these are high-tensile, عزم الدوران السائد “قفل” المكسرات. They are either metal-lock (with distorted threads) or nylon-insert (نيلوك) المكسرات.

هذا “قفل” logic is a non-negotiable safety requirement for the مجموعة التعليق الخلفي FAW للكابينة. A standard nut would vibrate loose from road shock and engine harmonics in a very short time. This would cause the bracket to shift, leading to catastrophic failure of the suspension.

إمكانية الخدمة (جامعة ولاية ميشيغان):

الجميع 36 fasteners are MSUs. Due to their “عزم الدوران إلى العائد” و “القفل الذاتي” nature, these fasteners are strictly **single-use**. Any time the مجموعة التعليق الخلفي FAW للكابينة is unbolted for service, a full new set of 18 bolts and 18 nuts *must* be used to guarantee the factory clamping force and vibration resistance.
