مجموعة حزام الأمان FAW J6P: تفكيك 4 الأجزاء المهمة لسلامة الركاب الخالية من العيوب

Welcome to the essential deconstruction of the مجموعة حزام الأمان FAW J6P لفاو جيفانغ CA3250P66K2L1T1E 6×4 تفريغ الشاحنة. This is the most critical passive safety system in the vehicle. هذا الدليل سوف يفكك 4 key components, from the main retractor to the buckle and trim, ensuring flawless technician service.

ال مجموعة حزام الأمان FAW J6P هو مجمع, engineered safety device. It is the primary restraint system, designed to work in fractions of a second to protect the driver and passenger during a sudden stop or collision. In the demanding environment of a 6×4 تفريغ الشاحنة, this system must withstand constant vibration and dust while remaining 100% موثوق.

This deconstruction will go beyond a simple parts list. We will analyze the pyrotechnic, ميكانيكية, and energy-absorbing logic built into each component. لفني, understanding this مجموعة حزام الأمان FAW J6P is not just about maintenance; it is about ensuring the vehicle’s core safety features are intact and functional. A seatbelt is a one-time-use device in a crash, and replacing it correctly is a critical, non-negotiable task.

جوهر 1: ال “Energy Management” منطق (The Outer Retractor)

This component is the heart of the مجموعة حزام الأمان FAW J6P. It houses the belt webbing and the majority of the safety mechanisms. The Qty 2 indicates this part (or its mirrored equivalent) is used for both driver and passenger sides.

1. عنصر: ‘Outer Seatbelt Assy’ (8212010-A86-C00) – الكمية 2
هذا (علامة 1) is the main retractor and webbing assembly. It is a highly complex, sealed unit that must not be tampered with. It contains multiple, distinct safety logics.

The Locking Logic (ELR): This is the fundamental feature. The assembly contains an Emergency Locking Retractor (ELR). This mechanism allows the belt to be pulled out slowly and retract freely, but it locks instantly during a sudden change in velocity (حادث تحطم) or a change in orientation (التمديد).

This is achieved mechanically, often with a small pendulum or ball-in-cage that is displaced by G-forces, triggering a locking pawl that engages the retractor’s gear. هذا هو “هَزَّة” sensitivity of the belt.

The Pyrotechnic Logic (Pretensioner): This is the active safety part of the مجموعة حزام الأمان FAW J6P. This retractor contains a pyrotechnic pretensioner. Upon receiving a signal from the truck’s airbag control unit (وحدة تنسيق الدعم), صغير, controlled explosive charge (a gas generator) حرائق.

This gas rapidly expands, spinning the retractor spool backwards *before* the occupant has moved forward. هذا “pre-tensions” the belt, removing all slack and pulling the occupant firmly into their seat. This action is critical for positioning the occupant correctly for the load-limiting phase.

The Webbing Logic: The belt itself is a key component. ال “حزام” is made from high-tensile, woven polyester, specifically designed to stretch in a controlled, predictable way. This stretch is not a flaw; it is an energy-absorbing feature. It acts like a spring, slowing the occupant’s deceleration and reducing the peak force transferred to their chest and pelvis.

The Load Limiter Logic: This is the final and most sophisticated logic. After the مجموعة حزام الأمان FAW J6P has pretensioned and the occupant’s full weight is thrown against the locked belt, an immense force is generated. To prevent the belt itself from causing severe chest or collarbone injuries, a load limiter is activated.

This is often a “torsion bar” inside the retractor spool. At a pre-set force (على سبيل المثال, 4 kilonewtons), this bar will twist, allowing the belt to “pay out” a few centimeters in a controlled manner. هذا “yielding” action absorbs the most violent peak forces of the impact, protecting the occupant.

منطق الخدمة: A deployed مجموعة حزام الأمان FAW J6P is a deployed pyrotechnic. It is a single-use device. Once the pretensioner has fired or the load limiter has been activated (which it will be in any significant collision), the entire assembly (8212010-A86-C00) is scrap. It *must* be replaced. It cannot be “reset.”

جوهر 2: ال “Secure Latch” منطق (The Buckle Assembly)

هذا هو “أنثى” half of the مجموعة حزام الأمان FAW J6P. It provides the secure locking point for the belt’s latch plate and communicates the belt’s status to the truck’s computer.

1. عنصر: ‘Left Buckle Assy’ (8212025-أ01) – الكمية 1
هذا (علامة 2) is the buckle assembly, المحددة ل “غادر” (driver’s) جانب. This implies it is different from the passenger side, likely due to its integrated electronics.

The Latching Logic: This is the core mechanical function. The assembly contains a high-strength, spring-loaded latch mechanism. It is designed to capture the belt’s metal tongue and lock it securely with a positive “انقر.” The red “PRESS” button is a mechanical release that must function easily for egress.

The mechanism is designed to be “over-center” و “load-proof,” meaning the harder the occupant pulls on it during a crash, the more securely it locks. It cannot be pulled open under load.

المنطق الكهربائي (Seatbelt Switch): هذا مجموعة حزام الأمان FAW J6P buckle is not just mechanical. It contains an integrated switch. This switch detects the presence of the metal latch plate. It is a simple open/close circuit that communicates with the vehicle’s body control module (مليار متر مكعب).

This switch is the logic that controls the “fasten seatbelt” warning light and audible chime on the dashboard. A failure of this switch (على سبيل المثال, light stays on even when buckled) is a common diagnostic item.

The Structural Logic: This buckle assembly is not bolted to the seat fabric. It is mounted via a short, high-tensile steel cable or a solid steel stalk, which is then bolted directly to the high-strength steel frame of the driver’s seat. This anchor point is just as strong as the retractor’s anchor.

منطق الخدمة: Like the retractor, this component is often a single-use device. Many buckles also contain a pretensioner (using a cable to pull the lap belt down). إذا كان هذا مجموعة حزام الأمان FAW J6P buckle has been part of a pyrotechnic deployment, يجب استبداله. A technician must also replace it if the switch fails or the mechanical latch becomes weak or damaged.

جوهر 3: ال “System Integration” منطق (The Protective Covers)

These components are the interior trim pieces that conceal and protect the مجموعة حزام الأمان FAW J6P آليات. They are safety components in their own right.

1. عنصر: ‘Left Side Panel Fixed Cover – Seatbelt’ (8212057-أ01) – الكمية 1
هذا (علامة 3) is the interior trim cover for the “غادر” (driver’s) جانب, likely covering the B-pillar where the retractor (جوهر 1) is mounted.

2. عنصر: ‘Right Side Panel Fixed Cover – Seatbelt’ (8212058-أ01) – الكمية 1
هذا (علامة 4) is the corresponding interior trim cover for the “يمين” (passenger’s) جانب, which also houses a مجموعة حزام الأمان FAW J6P ضام.

The Protective Logic: The most basic function of these covers is cosmetic and protective. They conceal the steel body of the cab and the retractor mechanism. They prevent dust, حطام, and moisture from fouling the مجموعة حزام الأمان FAW J6P آلية, which could cause it to jam.

They also protect the webbing from UV light from the sun, which can degrade the polyester fibers and weaken the belt over many years.

The ‘Tear-Seam’ منطق: هذا أمر بالغ الأهمية, non-obvious safety logic. These covers are not just simple plastic. They are engineered with “tear-seams” أو “الانفصالية” points, especially if the vehicle is equipped with side-curtain airbags.

If an airbag or the مجموعة حزام الأمان FAW J6P itself needs to deploy with massive force, this cover is designed to split open in a controlled, predictable way. This allows the safety device to deploy correctly without sending plastic shrapnel into the cabin.

The Guide Logic: These covers also incorporate the upper “حلقة D” or guide for the seatbelt. This is a plastic or metal loop that guides the webbing from the retractor to the occupant’s shoulder. This loop is made of a low-friction material to allow the belt to move smoothly and, بشكل حاسم, is anchored to the steel pillar to take the full crash load.

منطق الخدمة: A technician must use extreme care when removing these panels. Using metal tools can damage the plastic, break the mounting clips (leading to rattles), أو, most critically, damage the hidden tear-seams. After a collision, these panels must be inspected and are often replaced as part of a full مجموعة حزام الأمان FAW J6P system replacement.
