لوحة السقف فاو J6P: تفكيك 17 الأجزاء المهمة للتحكم في ناقل الحركة بشكل لا تشوبه شائبة

Welcome to this specialized deconstruction of the لوحة السقف فاو J6P, the top cover assembly for the CA10TA160M 10-speed transmission. This guide is for the FAW Jiefang CA3250P66K2L1T1E 6×4 تفريغ الشاحنة, analyzing the 17 components that form the لوحة السقف فاو J6P, the critical interface between the driver’s shift lever and the gearbox’s internal rails.

ال لوحة السقف فاو J6P هو “Human-Machine Interface” of the gearbox. Its logic is to translate the driver’s “X-Y” (side-to-side and fore-aft) hand movements into a precise, isolated “ض” (downward) motion onto the correct shift rail. This assembly ensures smooth, precise gear selection and is the key to the entire shift-feel and interlock system.

جوهر 1: ال “الهيكلية & ختم” منطق (The Housing)

This group represents the foundational “الهيكل” of the entire shift lever mechanism. All other components in this list are mounted *inside* or *onto* this single part, ال لوحة السقف فاو J6P.

1. عنصر: ‘Top cover’ (1702211A703)
هذا (شركات 5) is the main ‘Top cover’, ال لوحة السقف فاو J6P casting. هذا هو واجب ثقيل, complex component, precision-cast from iron or aluminum. Its logic is threefold:

ال Alignment Logic is its most critical function. ال لوحة السقف فاو J6P is machined with precise, parallel bores. These bores are the “tunnels” that support the ‘Shift shaft’ (شركات 11) and ‘Select gear arm’ (شركات 15), ensuring they move smoothly and engage the internal rails perfectly.

ال منطق الختم is its second function. This component acts as the final “سَطح” ل “Upper Cover” حَشد, sealing the shift mechanism from the elements. It is sealed to the lower housing by the ‘Gasket’ (شركات 10).

2. عنصر: ‘Gasket – top cover’ (1702216-A7G)
هذا (شركات 10) is the main static seal. This precision-cut gasket sits between this لوحة السقف فاو J6P (شركات 5) and the ‘Upper Cover’ (from the previous breakdown, item 56). Its logic is to prevent high-temperature oil “splash” from escaping the gearbox and to keep water/dirt *out* of the shift mechanism.

3. عنصر: ‘Breather plug assy’ (1702240-A7G)
هذا (شركات 9) هو “رئة” of the entire gearbox. هذا FAW J6P عنصر الاتصال (as it is also a connector) threads into the لوحة السقف فاو J6P.

إنه Venting Logic أمر بالغ الأهمية. As the gearbox heats up, the oil and air inside expand, creating positive pressure. This ‘Breather plug’ is a one-way valve that “exhales” this pressure. This prevents the pressure from building up and blowing out the main oil seals (like Comp 3 و 8).

جوهر 2: ال “Shift” منطق (Fore-Aft Motion)

This group represents the components in the لوحة السقف فاو J6P that are responsible for the driver’s “push-pull” (forward-and-backward) motion. هذا هو “Y-axis” of the H-pattern, which engages the gear.

1. عنصر: ‘Shift shaft & arm assy’ (1702220A703)
هذا (شركات 11) is the core “shift shaft.” The external “arm” of this assembly connects to the driver’s shift lever linkage. ال “shaft” portion slides fore-and-aft *inside* the bores of the لوحة السقف فاو J6P (شركات 5).

ال Actuation Logic is to transfer the “push/pull” motion from the driver, down through the لوحة السقف فاو J6P, to the ‘Shift selector head’ (شركات 12).

2. عنصر: ‘Shift selector head’ (1702231A703)
هذا (شركات 12) هو “finger” at the bottom of the ‘Shift shaft’ (شركات 11). Its logic is to be the single part that engages the “gates” on the shift rails (housed in the cover *below* this لوحة السقف فاو J6P). When the driver pushes forward, هذا “head” pushes the selected shift rail forward.

3. ال “Shift Shaft Bushing & ختم” مجموعة (شركات 3, 4, 7, 8)
This group includes: ‘Top cover oil seal assy – shift shaft’ (شركات 3 & 8) and ‘Sliding bush – top cover’ (شركات 4 & 7).

ال Bushing Logic is for smooth operation. The two ‘Sliding bushes’ (شركات 4, 7) are low-friction liners pressed into the لوحة السقف فاو J6P (شركات 5). They allow the ‘Shift shaft’ (شركات 11) to slide back and forth with minimal effort and no metal-on-metal contact.

ال Dynamic Seal Logic is the job of the two ‘Oil seal assemblies’ (شركات 3, 8). These are critical *dynamic* seals. They are mounted in the لوحة السقف فاو J6P to prevent gearbox oil from “splashing” up the shift shaft and leaking out of the top of the transmission.

جوهر 3: ال “Select” منطق (Side-to-Side Motion)

This group represents the components in the لوحة السقف فاو J6P that handle the driver’s “side-to-side” motion. هذا هو “X-axis” of the H-pattern, which *selects* which shift rail to engage.

1. عنصر: ‘Select gear arm’ (1702241A703)
هذا (شركات 15) is the ‘Select gear arm’. This component is also connected to the driver’s shift lever linkage. Its logic is to *rotate* the ‘Shift shaft’ (شركات 11) along its long axis.

هذا Rotational Logic is what moves the ‘Shift selector head’ (شركات 12) from side-to-side. This action is what “selects” which shift rail (1/ر, 2/3, أو 4/5) the ‘Shift selector head’ is aligned with, *before* the driver “shifts” (pushes/pulls) هو - هي. هذا هو “selector” جزء من لوحة السقف فاو J6P آلية.

2. ال “Safety Lock” مجموعة (شركات 16, 17)
This group includes: ‘Fastening screw’ (شركات 16) and ‘Steel wire lock line’ (شركات 17).

ال Critical Fastener Logic is their function. The ‘Fastening screw’ (شركات 16) is what locks the ‘Select gear arm’ (شركات 15) to its shaft. Because this fastener is *inside* the لوحة السقف فاو J6P, it must *never* come loose.

The ‘Steel wire lock line’ (شركات 17) هو “fail-safe” device. This wire is threaded through a hole in the head of the screw (شركات 16) and twisted, making it physically *impossible* for the screw to vibrate loose. This is a critical safety feature of the لوحة السقف فاو J6P حَشد.

جوهر 4: ال “قفل & Linkage” منطق (الأجهزة)

This final group includes all the miscellaneous hardware that mounts the لوحة السقف فاو J6P to the gearbox and connects the external linkages.

1. ال “Mounting Bolt” مجموعة (شركات 6, 13, 14)
This group includes: ‘Hexagon flange bolt’ (شركات 6, الكمية 4), ‘Spring washer’ (شركات 13, الكمية 1), and ‘Hexagon head bolt with guide neck’ (شركات 14, الكمية 1).

ال Clamping Logic is their function. These are the main bolts that securely fasten the لوحة السقف فاو J6P (شركات 5) إلى “Upper Cover” (from the previous breakdown, item 56).

The ‘Flange bolts’ (شركات 6) are self-locking and resist vibration. The ‘Guide neck’ الترباس (شركات 14) is a high-precision bolt, likely used at a critical alignment point, with a ‘Spring washer’ (شركات 13) to provide constant tension. These ensure the لوحة السقف فاو J6P remains rigid and oil-tight.

2. ال “Linkage” مجموعة (شركات 1, 2)
This group includes: ‘Dust cover – top cover’ (شركات 1, الكمية 2) and ‘Lever transmission type hose clamp’ (شركات 2).

ال Protection Logic is the job of the ‘Dust cover’ (شركات 1). These are flexible rubber “bellows” أو “boots” that slide over the external shift linkages (like the ‘Select gear arm’). They protect the pivot joints from dirt, sand, والماء, which would quickly wear them out.

ال Clamping Logic of the ‘Hose clamp’ (شركات 2) is to securely fasten these ‘Dust covers’ (شركات 1) onto the linkages, ensuring a tight seal. These are essential for the long-term reliability of the لوحة السقف فاو J6P‘s external mechanism.
