العلبة الفرعية FAW J6P: تفكيك 22 الأجزاء المهمة لضمان سلامة مجموعة نقل الحركة التي لا تشوبها شائبة

مرحبًا بكم في هذا التحليل الخبير لـ العلبة الفرعية FAW J6P, the foundational housing for the CA10TA160M auxiliary gearbox. هذا المكون ضروري لـ FAW Jiefang CA3250P66K2L1T1E 6×4 تفريغ الشاحنة. يقوم هذا الدليل بتحليل 22 part types that seal, يدعم, and complete the العلبة الفرعية FAW J6P (مع مأخذ الطاقة) for professional service.

ال العلبة الفرعية FAW J6P هو “الهيكل” of the 10-speed transmission’s range box. Its logic is to provide a perfect, rigid alignment for the high-torque auxiliary countershafts and the main spindle. It also contains the oil and provides the mounting point for the critical Power Take-Off (مأخذ الطاقة) وحدة.

جوهر 1: ال “الهيكلية” منطق (The FAW J6P Sub-Enclosure & مأخذ الطاقة)

This group contains the main structural casting, ال “الهيكل” of the auxiliary gearbox, and the lifting lug used to service it. ال العلبة الفرعية FAW J6P is the literal foundation.

1. عنصر: ‘Sub-box housing’ (1701501AA1K)
هذا (شركات 2) هو العلبة الفرعية FAW J6P نفسها. هذا ضخم, مكون معقد, precision-cast from high-strength iron or aluminum. منطقها ثلاثي: تنسيق, ختم, and heat dissipation.

ال منطق المحاذاة هي وظيفتها الأكثر أهمية. This main case has multiple, perfectly parallel bores machined into it to hold the bearings for the ‘Sub-Box Spindle’ and the various countershafts (like the ‘Left Upper’ and ‘Right Lower’ مهاوي). Any warping or damage to the العلبة الفرعية FAW J6P will cause shaft misalignment, leading to rapid gear and bearing failure.

ال منطق الختم is its obvious function. It acts as a large “مستنقع” أو “oil bath” for the auxiliary gear set. It is designed with multiple machined faces for gaskets (مثل شركات 1, 7, 21) to create a leak-proof enclosure.

ال PTO Port Logic is its special feature. المذكرة “(مع إقلاع الطاقة)” (مع مأخذ الطاقة) on the diagram title confirms this العلبة الفرعية FAW J6P is cast with a standardized 6-bolt or 8-bolt “نافذة” أو “aperture” on the side. This port is designed to mount the truck’s hydraulic pump PTO, allowing the gearbox to power the dump body.

2. عنصر: "عروة الرفع."’ (1702096-A7G)
هذا (شركات 18) is a heavy-duty steel bracket bolted to the top of the العلبة الفرعية FAW J6P (باستخدام البراغي شركات 19).

ال منطق الخدمة هي وظيفتها. A complete transmission assembly is extremely heavy. This ‘Lifting lug’ يوفر آمنة, balanced attachment point for an engine hoist or chain, allowing technicians to safely remove and install the entire gearbox from the truck’s chassis.

جوهر 2: ال “Output Shaft Seal” منطق (Spindle Interface)

This group is dedicated to sealing the largest, most critical rotating component of the العلبة الفرعية FAW J6P: the final output shaft (spindle).

1. عنصر: ‘Rear bearing cover – sub-box output shaft’ (1701586-A7K)
هذا (شركات 8) is the main bearing retainer for the ‘Sub-Box Spindle’. إنها كبيرة, cast cover that bolts to the very back of the العلبة الفرعية FAW J6P (باستخدام البراغي شركات 16).

ال Bearing Pre-load Logic is this cover’s primary job. هو - هي “traps” the outer race of the ‘Double-row tapered roller bearing’ (from the Spindle assembly). الحشية – رمح الإخراج’ (شركات 7) sits between this cover and the main housing, and its thickness is critical for setting the spindle’s bearing pre-load.

2. عنصر: ‘Oil seal assy’ (1701605-A7G)
هذا (شركات 15) is the main output shaft oil seal. It is pressed *into* the ‘Rear bearing cover’ (شركات 8).

ال منطق الختم is this component’s “no-fail” وظيفة. It is the final, dynamic seal of the entire drivetrain. Its flexible lip rides on the spinning ‘Output flange’ (from the Spindle assembly). Its logic is to keep 100% of the gear oil *inside* the العلبة الفرعية FAW J6P while keeping 100% of road dirt, ماء, والحطام *خارج*. A failure here results in a major, high-speed oil leak.

جوهر 3: ال “Countershaft Pre-load” منطق (The Shim Stack)

This group contains the hardware for sealing and, الأهم من ذلك, setting the pre-load for the auxiliary countershafts (like the ‘Left Upper’ and ‘Right Lower’ مهاوي) as they mount into the العلبة الفرعية FAW J6P.

1. عنصر: ‘Rear bearing cover – sub-box intermediate shaft’ (1701521-A7G)
هذا (شركات 20) is the bearing retainer for one of the countershafts. It is a cover that bolts to the العلبة الفرعية FAW J6P, “trapping” the outer race of the shaft’s tapered roller bearing.

2. عنصر: "حشية." – sub-box intermediate shaft’ (1701523-A7G)
هذا (شركات 21) is the paper or cork gasket that seals the ‘Bearing cover’ (شركات 20) إلى العلبة الفرعية FAW J6P, preventing oil leaks from the bearing bore.

3. عنصر: ‘Adjusting gasket (الرقائق) – sub-box intermediate shaft’ (شركات 22)
هذا (شركات 22) represents a large set of ‘Adjusting gaskets’, أو “الحشوات,” of various, precisely-controlled thicknesses (على سبيل المثال, 1701526-A7G, 1701527-A7G, إلخ.). They are listed as “As required.”

ال منطق التحميل المسبق is the most high-precision task in servicing the العلبة الفرعية FAW J6P. Tapered roller bearings on the countershafts require a specific “التحميل المسبق” (ضغط) لتعمل. A technician assembles the shaft, measures the “نهاية اللعب” مع مؤشر الطلب, and then selects *one* shim (or a stack) from this group.

This shim (شركات 22) is placed *between* the ‘Bearing cover’ (شركات 20) and the ‘Gasket’ (شركات 21). Its exact thickness is what “مجموعات” the bearing pre-load. Using the wrong shim will cause the bearing to fail very quickly. وهذا يجعل العلبة الفرعية FAW J6P a high-precision item to service.

جوهر 4: ال “عداد السرعة & قفل” منطق (جميع الأجهزة)

This final group includes all the miscellaneous hardware that completes the العلبة الفرعية FAW J6P حَشد, from the speedometer drive to the myriad of fasteners.

1. ال “عداد السرعة” مجموعة (شركات 9, 10, 11, 12, 13, 14)
This is the complete assembly for the mechanical speedometer drive. It includes the ‘Lever – لمحرك عداد السرعة’ (شركات 9), the ‘Joint – speedometer flexible shaft’ (شركات 11), a ‘Fastening screw’ (شركات 14), and ‘O-ring seals’ (شركات 10, 12) with a ‘Spring washer’ (شركات 13) for the screw.

ال منطق القيادة is how the truck’s dashboard gets its speed reading. A plastic “معدات سبيدو” (على محور الدوران الفرعي) spins the ‘Lever’ (شركات 9). This ‘Lever’ (or drive gear) is housed in the ‘Joint’ (شركات 11), which is a 90-degree adapter that bolts to the العلبة الفرعية FAW J6P. The truck’s flexible speedometer cable then screws onto this ‘Joint’.

ال منطق الختم for this sub-assembly is the job of the two ‘O-ring rubber seals’ (شركات 10 و 12). These are critical for preventing gear oil from wicking up the speedometer drive and leaking out of the العلبة الفرعية FAW J6P.

2. ال “قفل & ختم” مجموعة (جميع الآخرين)
This group contains all the hardware (شركات 1, 3, 4, 5, 6, 16, 17, 19) الذي يحمل العلبة الفرعية FAW J6P معاً.

ال المنطق السحابي includes a large assortment of high-tensile bolts: 'مسمار رأس سداسي مع رقبة توجيه’ (شركات 4, 5, 6) و 'مسمار شفة مسدس’ (شركات 16, 17, 19). ال “دليل الرقبة” bolts are for high-precision alignment of bearing covers. ال “شفة” bolts have a built-in washer to resist vibration.

ال منطق الختم is provided by ‘Gasket’ (شركات 1), "حشية." – رمح الإخراج’ (شركات 7), and the ‘Spring washers’ (شركات 3). The gaskets provide the “ختم ثابت” between flat, metal surfaces. ال 19 "غسالات الربيع."’ (شركات 3) are the primary “المضادة للاهتزاز” منطق, providing constant tension on the bolts to prevent them from backing out and causing a catastrophic oil leak or misalignment of the العلبة الفرعية FAW J6P.
