السكك الحديدية دليل نافذة الباب الأمامي: تفكيك 8 الأجزاء المهمة للتشغيل الخالي من العيوب

Welcome to this critical deconstruction of the السكك الحديدية دليل نافذة الباب الأمامي نظام FAW Jiefang CA3250P66K2L1T1E 6×4 تفريغ الشاحنة. This guide analyzes the 8 key component types that create the entire assembly. This system is essential for smooth, quiet, and reliable window operation.

ال السكك الحديدية دليل نافذة الباب الأمامي is a complex, precision-engineered system. It is not just one part, but a series of interconnected channels, rails, and seals that must work in perfect harmony. This analysis will deconstruct the glass panel itself, the flocked (felt-lined) channels, the rigid metal guide rails, and the essential waterproof membranes, all of which are critical for performance in a high-vibration dump truck environment.

جوهر 1: The ‘Safety & Barrier’ منطق (The Glass Panel)

This component is the primary moving part of the السكك الحديدية دليل نافذة الباب الأمامي نظام. It is the component that the entire mechanism is designed to support and move.

1. عنصر: ‘Left/Right front door glass’ (6103021-أ01 / 6103022-أ01) – الكمية 1 كل
هذا (شركات 1) is the main door glass, supplied as mirrored Left and Right components. This is not standard glass; it is automotive-grade tempered safety glass.

The Safety Logic is its legal and functional mandate. Tempered glass is heat-treated to be several times stronger than annealed glass. In the event of a catastrophic impact, it is designed to shatter into thousands of small, blunt-edged pebbles, rather than large, شظايا خطيرة. This is a critical safety feature.

The Precision Logic is also key. This glass is not flat. It is precisely curved to match the contour of the J6P cab, maximizing visibility and reducing wind noise. Its edges are diamond-polished to be perfectly smooth.

This smoothness is essential for the السكك الحديدية دليل نافذة الباب الأمامي نظام, as it allows the glass to slide against the flocked channels (شركات 2) without snagging or damaging the delicate felt lining. A poorly-finished edge would destroy the channel and cause the window to jam.

جوهر 2: The ‘Frictionless Seal’ منطق (The Flocked Channel)

This component is perhaps the most important for driver comfort and window motor longevity within the السكك الحديدية دليل نافذة الباب الأمامي نظام.

1. عنصر: ‘Left/Right front door glass channel’ (6103051-أ01 / 6103052-أ01) – الكمية 1 كل
هذا (شركات 2) هو الرئيسي “run channel” that frames the visible part of the door. الزجاج (شركات 1) slides up and down inside this C-shaped channel.

The Flocked Logic is its distinguishing feature. The inside of this rubber channel is lined with a soft, felt-like material called “flocking.” This is not just for show; it is a high-technology surface.

This flocking serves two purposes: أولاً, it drastically reduces friction, allowing the glass to slide with minimal effort. This reduces the strain on the window regulator motor, preventing premature burnout. ثانية, it gently wipes the glass as it moves, and it acts as a superior acoustic and water seal, blocking wind noise and rain.

The Failure Logic for the السكك الحديدية دليل نافذة الباب الأمامي often starts here. After years of use, this flocking wears away. The glass then rubs (and chatters) against hard rubber. This increases friction dramatically, causing the window to become slow, jerky, or stuck, and is a primary cause of window motor failure.

جوهر 3: The ‘Structural Track’ منطق (The Metal Rails)

This group represents the rigid, internal “skeleton” التابع السكك الحديدية دليل نافذة الباب الأمامي نظام. These metal tracks guide the window regulator mechanism *inside* the door.

1. عنصر: ‘Left/Right front door front-lower guide rail assy’ (6101445-أ01 / 6101450-أ01) – الكمية 1 كل
2. عنصر: ‘Left/Right front door rear-lower guide rail’ (6101481-أ01 / 6101482-أ01) – الكمية 1 كل
هؤلاء (شركات 3 و 6) are the two primary metal guide rails, a front and a rear, for each door. The window regulator (the motor and scissor-lift) mounts to these rails.

The Alignment Logic is their sole purpose. These rails must be perfectly parallel and rigidly bolted to the door shell. They form the unmoving track that the regulator’s “skates” slide on. The glass panel is attached to this regulator. لذلك, these rails are 100% responsible for ensuring the glass travels up and down perfectly straight, without tilting.

If one of these rails is even slightly bent (from an accident or improper service), the window will bind, مربى, و “come off the track.” شركات 3 هو “حَشد” (حَشد), suggesting it may include its own mounting brackets, while Comp 6 is the rail itself.

جوهر 4: The ‘Transition Channel’ منطق (The Lower Channels)

هذه المجموعة من المكونات (شركات 5 و 7) acts as the “hand-off” within the السكك الحديدية دليل نافذة الباب الأمامي نظام, guiding the glass as it moves at the bottom of its travel.

1. عنصر: ‘Left/Right front door glass front-lower channel’ (6103053-أ01 / 6103054-أ01) – الكمية 1 كل
2. عنصر: ‘Left/Right front door glass rear-lower channel’ (6103057-أ01 / 6103058-أ01) – الكمية 1 كل
These four parts (two pairs, front and rear) are the lower, non-flocked guide channels.

The Transition Logic is their function. The glass is guided by two different systems: inside the door, it is held by the regulator (which rides on rails 3 & 6). In the visible “أعلى” موضع, it is held by the flocked channel (شركات 2).

These lower channels (شركات 5 & 7) manage the transition between these two systems. They are located at the bottom of the door, near the beltline. They help “catch” the glass as it comes down and guide it, ensuring it stays aligned as it disengages from the main flocked channel. These are typically made of a hard, low-friction plastic.

جوهر 5: The ‘Environmental & قفل’ منطق

This final group consists of the shield that protects the cab interior and the hardware that holds the rigid السكك الحديدية دليل نافذة الباب الأمامي components in place.

1. عنصر: "غشاء مقاوم للماء." – جانب’ (5302821-أ01) – الكمية 4
هذا (شركات 8) أمر بالغ الأهمية, but often-overlooked, عنصر. This is a thin plastic “watershed” sheet that is sealed to the inner door frame, *behind* the interior trim panel.

The Water-Shedding Logic is vital. Rainwater that gets past the outer window seal is *supposed* to drip down *inside* the door. This membrane’s job is to catch that water and channel it safely to the drain holes at the bottom of the door. بدونه, water would soak into the back of the interior trim panel and leak onto the cab floor. كمية 4 suggests two per door, or that they are also used on the rear cab wall.

2. عنصر: ‘Hexagon flanged bolt’ (Q1840616F6) – الكمية 8
هذا (شركات 4) is the hardware that holds the rigid السكك الحديدية دليل نافذة الباب الأمامي system together. هؤلاء 8 البراغي (4 per door) are used to mount the front and rear metal rails (شركات 3 & 6) to the door shell.

The Flange Logic is a vibration-proof design. ال “شفة” is a built-in washer. This distributes the clamping force over a wider area (preventing pull-through) و, when tightened, acts as a lock washer. This is essential to ensure the rails *never* loosen, as any shift would cause the entire window to jam.
