فاو J6P المحور الثاني: تفكيك 14 الأجزاء المهمة لإخراج تروس لا تشوبه شائبة

Welcome to this critical deconstruction of the فاو J6P المحور الثاني, also known as the mainshaft, for the CA10TA160M gearbox in the FAW Jiefang CA3250P66K2L1T1E 6×4 تفريغ الشاحنة. This technical guide analyzes the 14 components that make up the complete فاو J6P المحور الثاني حَشد, which is the heart of the transmission’s “الإخراج” منطق.

ال فاو J6P المحور الثاني is the output shaft of the main 5-speed gear case. Its logic is to hold all the “driven” التروس (1st-4th, Reverse) and the synchronizer sleeves that lock them. The integrity of this one shaft and its components is directly responsible for every gear shift and all power delivery to the wheels.

جوهر 1: ال “Shaft & Gear Set” منطق (The FAW J6P Second Axis)

This group represents the “العمود الفقري” و “driven gears” of the main gearbox. ال فاو J6P المحور الثاني is the component that the driver is “ربط” to when they select a gear.

1. عنصر: ‘Second axis’ (1701301-A7G)
هذا (شركات 1) is the ‘Second axis’ نفسها, the mainshaft. This is a long, heavy-duty shaft, precision-machined from hardened steel with multiple steps and grooves. Its logic is to act as the central “العمود الفقري” for all the main driven gears.

ال Alignment Logic أمر بالغ الأهمية. الجبهة “tip” of this فاو J6P المحور الثاني is supported by the pilot bushing *inside* the ‘First Axis’ (input shaft). The rear of the shaft is supported by a large bearing in the back of the gearbox case. This two-point support keeps it perfectly concentric.

ال Gear Carrier Logic is its main function. ال “steps” on the shaft are smooth, hardened surfaces on which all the free-spinning gears (شركات 5, 10, 12, 13, 14) ride, usually on needle bearings. ال “splined” sections are where the ‘Sliding gear sleeves’ (شركات 8) are mounted, which are the parts that lock the gears to the فاو J6P المحور الثاني.

2. The Driven Gears (شركات 5, 10, 12, 13, 14)
This group includes: ‘Reverse gear’ (شركات 5), ‘First gear’ (شركات 10), ‘Second gear’ (شركات 12), ‘Third gear’ (شركات 13), and ‘Fourth gear’ (شركات 14).

ال Freewheeling Logic is the key concept. All five of these “driven gears” are in *constant mesh* with their respective drive gears on the countershaft. لكن, they are *not* fixed to the فاو J6P المحور الثاني. They all spin freely on the shaft at different speeds.

When the driver selects “3rd gear,” they are *not* moving the gear itself. They are moving a ‘Sliding gear sleeve’ (شركات 8) ل “lock” the ‘Third gear’ (شركات 13) إلى فاو J6P المحور الثاني. At that moment, power flows from the countershaft, through the now-locked Comp 13, and out through the فاو J6P المحور الثاني.

جوهر 2: ال “ارتباط” منطق (Sleeves & Keys)

This group contains the components that perform the physical “locking” of the gears to the فاو J6P المحور الثاني. This is the core of the synchronizer assembly.

1. عنصر: ‘Sliding gear sleeve’ (1701316-A7G) – الكمية 3
هذا (شركات 8) is the ‘Sliding gear sleeve’. There are three of them, likely for the 1-2 shift, ال 3-4 shift, and the Reverse shift. This is the component that the driver’s shift fork physically slides back and forth on the splines of the فاو J6P المحور الثاني.

ال Locking Logic is its function. The ‘sleeve’ has internal splines that match the فاو J6P المحور الثاني. When the driver shifts, this sleeve slides over a set of external “dog teeth” on the side of the target gear (على سبيل المثال, ‘First gear’, شركات 10). This creates a solid, positive, non-slip lock, making the gear and the shaft spin as one unit.

2. ال “Detent Key” مجموعة (شركات 3, 4)
This group includes: ‘Three-sided key’ (شركات 3) and ‘Snap ring – مفتاح ثلاثي الجوانب’ (شركات 4). هذا هو “synchronizer key” أو “strut.”

ال Detent Logic is the function of the ‘Three-sided key’ (شركات 3). This small key sits in a groove in the synchronizer hub (which is splined to the فاو J6P المحور الثاني) and is pushed outwards by a spring (غير مدرجة) into a groove *inside* the ‘Sliding gear sleeve’ (شركات 8).

This key is what creates the “neutral” position for the sleeve. يوفر “snap” و “انقر” feeling in the gear lever. The ‘Snap ring’ (شركات 4) is a small retainer that holds this key in its slot, preventing it from falling out during assembly or operation.

جوهر 3: ال “Positioning & فاصل” منطق (غسالات)

This final group of components is arguably the most critical for a long-lasting, quiet فاو J6P المحور الثاني. Their logic is to precisely control the “end play” and spacing of all the spinning gears.

1. ال “Reverse Gear” Spacer Group (شركات 6, 7)
This group includes: ‘Positioning washer – العتاد العكسي’ (شركات 6) and ‘Limiting washer – العتاد العكسي’ (شركات 7). These are the dedicated spacers for the ‘Reverse gear’ (شركات 5).

ال Thrust Logic is their function. The ‘Positioning washer’ (شركات 6) likely sits behind the gear, setting its base position on the فاو J6P المحور الثاني. The ‘Limiting washer’ (شركات 7) sits on the other side. معاً, these washers create a “sandwich” that controls the gear’s “axial play” (fore-and-aft movement). This precise spacing is essential for proper engagement with the reverse idler gear and the synchronizer sleeve.

2. ال “Main Gear” Spacer Group (شركات 9, 11)
This group includes: ‘Limiting washer – العتاد’ (شركات 9, الكمية 4) and ‘Inter-shaft limiting washer’ (شركات 11, الكمية 2).

ال Spacer Logic is the job of the ‘Limiting washers’ (شركات 9). These four washers are the “spacers” that sit on the فاو J6P المحور الثاني *between* the free-spinning gears (على سبيل المثال, between 1st and 2nd, 2nd and 3rd, إلخ.). They prevent the hardened gears from rubbing directly against each other, which would generate immense heat and destructive metal particles.

ال Thrust Bearing Logic is the job of the ‘Inter-shaft limiting washers’ (شركات 11). These are likely the main “thrust washers” for the entire gear set, located at the front and back of the gear stack. They absorb the massive axial forces generated by the helical-cut gears, protecting the فاو J6P المحور الثاني bearings from being destroyed.

3. عنصر: ‘Spring cylindrical pin’ (Q5280310)
هذا (شركات 2) is a ‘Spring cylindrical pin’, also known as a “roll pin.” إنه Locking Logic is to act as a secure, vibration-proof fastener. It is likely used to lock the main shift rail (which moves the forks) in place, or to secure a synchronizer hub (which holds Comp 3) إلى فاو J6P المحور الثاني, preventing it from rotating or sliding.
