مسند ذراع للباب الأمامي FAW J6P: تفكيك 4 الأجزاء المهمة لراحة السائق التي لا تشوبها شائبة

Welcome to this detailed deconstruction of the مسند ذراع للباب الأمامي FAW J6P, a key interior component for the FAW Jiefang CA3250P66K2L1T1E 6×4 تفريغ الشاحنة. This guide analyzes the 4 critical component types that form the complete armrest and sealing system. This is a vital driver touchpoint, engineered for comfort.

ال مسند ذراع للباب الأمامي FAW J6P is more than a simple comfort piece; it is a structural part of the interior door panel. It must be robust enough to be used as a “يحذب” handle to close the heavy-duty door, while also being ergonomically sound for long-haul driver comfort. This analysis will deconstruct the armrest assembly itself, its mounting hardware, the critical environmental seal, and the door foundation it mounts to.

جوهر 1: The ‘Ergonomic & الهيكلية’ منطق (The Armrest)

This is the primary component of the مسند ذراع للباب الأمامي FAW J6P نظام. It is the part the driver physically interacts with, designed for both comfort and structural integrity.

1. عنصر: ‘Left/Right front door armrest assembly’ (6102125-B27 / 6102130-B27) – الكمية 1 كل
هذا (شركات 2) is the complete armrest unit. ال “حَشد” name is key, as it is not just a soft pad. It consists of a rigid, structural polymer core, which is then wrapped in a durable, easy-to-clean vinyl or polyurethane “skin” with a cushioning foam layer.

The Ergonomic Logic is its primary function. The shape is contoured to comfortably support the driver’s arm during long-haul drives, reducing fatigue. It is also shaped to act as a powerful “pull handle” for closing the heavy cab door.

The Structural Logic is its hidden feature. The inner core of this مسند ذراع للباب الأمامي FAW J6P contains the reinforced mounting bosses. The eight screws (شركات 3) pass through the door’s interior trim panel and bolt directly into these bosses. This ensures that when a driver pulls the armrest, they are pulling on a component that is structurally secured, not just attached to the cosmetic trim.

The Symmetrical Logic is critical for part replacement. The Left (6102125-B27) and Right (6102130-B27) armrests are mirror images and are not interchangeable. They are molded specifically for the driver and passenger sides.

جوهر 2: The ‘Environmental Seal’ منطق (The Sealing Membrane)

هذا المكون, while hidden behind the door trim, is essential for protecting the cab interior and is a critical part of the مسند ذراع للباب الأمامي FAW J6P نظام.

1. عنصر: ‘Left/Right front door sealing membrane’ (6102187-أ01 / 6102188-أ01) – الكمية 1 كل
هذا (شركات 4) هو “vapor barrier” أو “watershed” for the door. It is a large, precisely-cut sheet of durable plastic or treated paper that is sealed against the inner door shell (شركات 1) with a sticky butyl adhesive.

The Water-Shedding Logic is its primary purpose. Automotive doors are not waterproof; they are water-managing. Rain and wash water that gets past the window’s outer seal (the beltline) is *designed* to drip down inside the door.

This membrane’s job is to act as an “مظلة,” catching this water and channeling it away from the interior trim panel (where the armrest mounts) and directing it safely to the drain holes at the bottom of the door.

A torn or poorly-sealed membrane is the number one cause of water leaks onto the cab floor, which can lead to mold and corrosion. Any service that requires removing the مسند ذراع للباب الأمامي FAW J6P or trim panel must be done carefully to avoid damaging this seal.

The Acoustic Logic is its secondary function. This membrane also provides a significant barrier for road and wind noise, isolating the door’s “wet” side from the “جاف” side and contributing to a quieter cab.

جوهر 3: The ‘Foundation’ منطق (The Door Shell)

This component is the literal foundation for the entire مسند ذراع للباب الأمامي FAW J6P حَشد. It is the structural, bare-metal door.

1. عنصر: ‘Left/Right front door weld assembly’ (6100055-B27 / 6100060-B27) – الكمية 1 كل
هذا (شركات 1) هو “Door-in-White” or the complete, welded-together door shell before paint and trim. It is the parent part to which all other components in this system (and others, like the lock and window) are mounted.

The Mounting Logic is key. The inner panel of this door shell is precision-stamped with the correct holes and reinforced bosses that align with the مسند ذراع للباب الأمامي FAW J6P. ال 8 screws (شركات 3) pass through the interior trim panel and secure the armrest directly to this metal foundation.

This direct metal-to-armrest-core connection is what gives the armrest its immense strength. If it were only attached to the plastic trim panel, it would break off the first time a driver used it to pull the door shut. The integrity of this “weld assembly” is what allows the armrest to function as a pull handle.

جوهر 4: The ‘Securing’ منطق (The Fasteners)

This final component is the hardware that physically connects the مسند ذراع للباب الأمامي FAW J6P to its foundation.

1. عنصر: ‘Cross recessed flat round head screw’ (س2360616) – الكمية 8
هذا (شركات 3) is the specified fastener. كمية 8 (four per armrest) indicates a stable, wide-stance mounting pattern designed to distribute the “pulling” force evenly.

The Fastening Logic is simple but critical. These screws are driven through the cosmetic interior door panel and thread into the structural core of the مسند ذراع للباب الأمامي FAW J6P (شركات 2) on the other side, sandwiching the door trim.

Unlike many other fasteners on the door, these are not listed as “combination screws” (with pre-installed lock washers). This is because they are threading into the plastic/polymer core of the armrest itself. The threads of the screw, combined with the material of the armrest core, are designed to create a secure, vibration-resistant joint.

The Service Logic is that these screws are often hidden under a cosmetic “fleece” or a small plastic cover inside the armrest’s grab handle. They must all be removed before the door panel can be taken off. Over-tightening these screws can strip the internal polymer threads, resulting in a loose مسند ذراع للباب الأمامي FAW J6P.
