FAW J6P توصيل رود: تفكيك 5 الأجزاء المهمة لموثوقية المحرك

مرحبا بكم في هذا التفكيك الخبير لل FAW J6P توصيل رود حَشد, the single most critical “force transfer” component in the engine of the FAW Jiefang CA3250P66K2L1T1E 6×4 تفريغ الشاحنة.

This is not a simple part; it is a “تجميع المنطق” engineered to survive the most hostile environment in the powertrain.

إنه “منطق” is to act as the “arm” that converts the linear, vertical force of the piston’s combustion into the rotational, torque-producing force of the crankshaft. This component is the very definition of “heavy-duty.”

جوهر “Design Logic” of this FAW J6P توصيل رود (P/N 1004021-36D) هو “fracture-split” manufacturing. Unlike older designs, ال “big end” cap is not sawn off; it is forged as a single piece and then *snapped* apart with a high-powered press. هذا “fracture logic” creates a perfectly irregular, 100% unique, and perfectly matched surface. This design is superior because it creates an unyielding lock that completely prevents “cap walk” (side-to-side movement) at high RPM, ensuring the hydrodynamic bearing stays perfectly round and functional.

يعد هذا الدليل الفني موردًا أساسيًا لمعيدي بناء المحركات, فنيين ورشة ماكينات, ومديري قطع غيار الأسطول. We will deconstruct the entire 5-component-type group associated with the FAW J6P توصيل رود. سنقوم بتحليل “Force Transfer Body” (the rod itself), ال “Pivot Point Logic” (the small-end bush), ال “Hydrodynamic Bearing Logic” (the upper and lower bearing shells), and the absolutely critical “المنطق السحابي” (the single-use, high-tension bolts).

جوهر 1: ال “Fracture-Split” Body Logic (عنصر 5)

This is the main structural component, the core of the FAW J6P توصيل رود.

1. عنصر: ‘Fracture-split connecting rod body’ (1004021-36د)
هذا المكون (شركات 5) is a masterpiece of modern metallurgy. إنه “منطق” is to handle two distinct and opposing forces. أولاً, it must withstand the “Compression Force”—the immense, 2000+ PSI crushing load from the combustion stroke. ثانية, it must withstand the “Tension Force”—the high-RPM “يحذب” أو “تمتد” force as the piston is yanked back down on the exhaust stroke. To handle this, ال FAW J6P توصيل رود يكون “drop-forged” (not cast) from a high-tensile steel alloy, often into a lightweight but incredibly strong “I-beam” profile.

As mentioned, إنه “Fracture-Split Logic” is its key manufacturing feature. This process creates a perfectly interlocking, non-slip cap. This is the only design that can reliably ensure the “big end” bearing bore remains perfectly round under the extreme, oscillating loads of a turbocharged diesel engine. This precision is what protects the bearings and crankshaft from failure, making the FAW J6P توصيل رود a true zero-compromise component.

جوهر 2: ال “Pivot Point” منطق (عنصر 4)

This component forms the “wrist” من الجمعية, the pivot point where the FAW J6P توصيل رود connects to the piston via the ‘Piston pin’.

1. عنصر: ‘Connecting rod small end bush’ (1004024-630-0000)
هذا (شركات 4) هو “Sacrificial Pivot Logic.” ال “small end” التابع FAW J6P توصيل رود oscillates back and forth on the hardened steel ‘Piston pin’. To prevent the hardened pin from destroying the forged steel rod, هذا “bush” is inserted. إنه أ “ذبيحة” عنصر. إنه “material logic” is that it is made from a softer, oil-retaining material (like a bronze alloy). It is designed to be the “wear item.”

إنه “fluid logic” is also critical. The bush often has a precise oiling hole or internal grooves that capture “splash” زيت, maintaining a constant film of lubrication for the piston pin. When an engine is rebuilt, replacing these 6 bushes is a mandatory step to restore the “like-new” precision to the FAW J6P توصيل رود حَشد.

جوهر 3: ال “Hydrodynamic Bearing” منطق (عناصر 6, 7)

This group’s “منطق” is to allow the “big end” التابع FAW J6P توصيل رود to spin at thousands of RPM on the crankshaft *without ever physically touching it*.

عناصر: ‘Connecting rod upper bearing’ (1004026-36د) & ‘Lower bearing’ (1004028-36د)
هذه هي “Hydrodynamic Logic” عناصر. ال “big end” التابع FAW J6P توصيل رود “floats” on a microscopic, high-pressure film of engine oil. These ‘bearings’ (شركات 6 & 7) are the precision, multi-layer, soft-metal shells that are engineered to hold this oil film. هُم “Sacrificial Logic” means they are the “wear item.” If any debris (carbon, metal) gets in the oil, it will embed in the soft bearing, saving the hardened, expensive crankshaft from scratches or “scoring.”

ال “Asymmetrical Load Logic” هو أيضا المفتاح. The ‘Upper bearing’ (شركات 6), which sits in the main rod body, takes the full, massive, downward *push* of the piston’s combustion stroke. The ‘Lower bearing’ (شركات 7), which sits in the cap, takes the high-RPM “whipping” *pull* on the exhaust and intake strokes. They are often engineered with different materials or features to handle these specific, opposing loads, ensuring the long-term reliability of the FAW J6P توصيل رود.

جوهر 4: ال “Critical Fastener” منطق (عنصر 8)

This final component is arguably the single most stressed fastener in the entire engine. إنه “منطق” is to provide a massive, unyielding clamping force.

1. عنصر: ‘Connecting rod bolt’ (1004023A29D)
القائمة تدعو إلى 12 البراغي (شركات 8), two for each of the six FAW J6P توصيل رود التجميعات. هذه هي “Clamping Force Logic.” They must handle the two opposing forces that try to rip the rod apart: ال “يدفع” from combustion and the “يحذب” from high-RPM “stretch.”

These are “عزم الدوران إلى العائد” (TTY) البراغي. هُم “منطق” is that they are designed to be torqued to a specific point where they *permanently stretch*. This stretching action turns the bolt into a high-tension spring, providing the perfectly consistent clamping force that the “fracture-split” cap (شركات 5) requires to stay locked in place. This is why they are *single-use*. Once stretched, they are compromised and MUST be replaced any time the FAW J6P توصيل رود is serviced. Re-using these bolts will lead to bearing failure and catastrophic engine destruction.
