انهيار الخبراء: دعامة تثبيت المحرك الأمامي FAW للجرار CA4251P66K24T1A3E5

Welcome to this expert-level guide focusing on the FAW دعامة تثبيت المحرك الأمامي (الجزء لا. 1001033-92دبليو), a fundamental structural component for the FAW Jiefang CA4251P66K24T1A3E5 6×4 جرار نصف مقطورة ديزل. This is a critical chassis-side component of the engine suspension system.

هذا المكون, ال FAW دعامة تثبيت المحرك الأمامي, serves as the immovable foundation upon which the engine’s vibration-damping “soft pad” التجميعات (analyzed in a separate guide) يتم تركيبها. Its sole purpose is to provide a high-strength, rigid connection point directly to the vehicle’s frame.

This technical analysis is designed for chassis technicians, fleet maintenance supervisors, and parts professionals who demand precision. We will deconstruct this assembly into its smallest serviceable units, examining the main bracket and the specific, high-tensile fasteners required for its safe installation.

Core Structural Analysis: The Bracket Itself (1001033-92دبليو)

The primary component in this assembly is the ‘Front Engine Mount Bracket’ (1001033-92دبليو). The parts list specifies a quantity of two, indicating a symmetrical pair for the left and right sides of the engine bay. This component is the non-wearing, static half of the engine mounting system.

This is not a simple piece of metal; it is a heavy-duty structural member, almost certainly manufactured from high-strength cast steel or forged iron. Its design is a feat of engineering, optimized to be as strong and rigid as possible while minimizing weight. It features complex curves and thick flanges designed to withstand the three primary forces acting upon it simultaneously.

أولاً, it must support the immense static weight of the front half of the powertrain. ثانية, it must act as the primary brace against the engine’s rotational torque, which can be thousands of newton-meters. ثالث, it must endure the constant, high-frequency vibrations from the diesel engine and the low-frequency, high-impact shocks from the road. ال FAW دعامة تثبيت المحرك الأمامي is the anchor that holds everything in place.

The Role of the Bracket in the Powertrain Suspension System

It is essential to understand where the FAW دعامة تثبيت المحرك الأمامي (1001033-92دبليو) fits into the complete system. This component serves as the critical intermediary between the truck’s frame and the engine’s active “ناعم” يتصاعد.

The complete system works in layers. The truck’s chassis frame rail is the foundation. ال FAW دعامة تثبيت المحرك الأمامي bolts directly and rigidly to this frame rail. Its precision-machined face then provides a perfect, solid mounting platform for the ‘Front Suspension Bracket Soft Pad Assembly’ (على سبيل المثال, part 1001040-92W, as seen in the previous assembly). هذا “soft pad” assembly is the hydraulic or elastomer mount that isolates vibration. أخيراً, ال “soft pad” assembly bolts to a corresponding bracket on the engine block itself.

لذلك, هذا FAW دعامة تثبيت المحرك الأمامي هو “جانب الهيكل” عنصر. Its exact placement, defined by its mounting holes, is critical for the entire powertrain’s alignment. If this bracket were to be installed incorrectly, or if it were to crack or bend, the engine would sit at an improper angle.

This misalignment would have a catastrophic ripple effect across the entire truck. A misaligned engine will cause the cooling fan to hit its shroud, put extreme stress on the radiator hoses, and misalign the exhaust system, causing it to crack. الأكثر أهمية, it will alter the driveshaft angle (powertrain inclination angle), leading to severe driveline vibration, قشعريرة, and the rapid destruction of U-joints and transmission output shaft bearings. ال FAW دعامة تثبيت المحرك الأمامي يكون, لذلك, a component that must have zero-tolerance for failure.

Chassis-to-Bracket Fasteners (Q1841460T)

The parts list specifies four units of ‘Hex Flange Bolt, Coarse Rod (نوع قياسي)’ (Q1841460T). These four bolts are the critical fasteners that connect the two FAW دعامة تثبيت المحرك الأمامي units directly to the truck’s chassis. Each bracket (اليسار واليمين) is likely secured by two of these massive bolts, which pass through the bracket and into threaded holes or nutserts in the frame rail.

هذه عالية الشد, safety-critical fasteners. ال “شفة” تصميم, which integrates a washer into the bolt head, is essential for spreading the massive clamping load, preventing the bolt head from “سحب من خلال” or cracking the bracket under extreme torque or shock loads. ال “ت” suffix on the part number almost certainly denotes a specific high-tensile strength class (على سبيل المثال, فصل 10.9) and a specialized anti-corrosion coating.

These bolts are subjected to incredible shear forces. When the truck hits a pothole, the entire weight and inertia of the engine is caught by these bolts. They must never be replaced with standard, lower-grade hardware. Using the genuine FAW دعامة تثبيت المحرك الأمامي fasteners and tightening them to the precise factory torque specification is mandatory for a safe repair.

Mount-to-Bracket Fasteners (Q1841455T)

The second set of fasteners listed are the four ‘Hex Head Flange Bolts’ (Q1841455T). These bolts are used for the next step in the assembly process: securing the ‘Front Suspension Bracket Soft Pad Assembly’ (the rubber/hydro mount) *to* the FAW دعامة تثبيت المحرك الأمامي.

The use of a different part number (1455T vs 1460T) متعمد. This bolt is of a different length, and possibly a different thread pitch, specifically engineered for the metal-to-metal connection of the “soft pad” assembly’s outer steel cage to this chassis bracket. مرة أخرى, these are flange-head bolts to ensure a high-strength, vibration-resistant joint that will not loosen over time.

In total, this simple-looking parts list describes a robust system: two brackets, four massive bolts to hold them to the frame, and four more high-tensile bolts to hold the engine’s active mounts. This creates a secure, double-fastened “شطيرة” that ensures the powertrain remains precisely where the engineers intended, حماية كامل FAW دعامة تثبيت المحرك الأمامي system from failure.
