Стопорное кольцо FAW: The 7 Основные MSU для идеального, Тихий, и безопасная кабина

Welcome to this critical component analysis of the Стопорное кольцо FAW, Positioning Pin, and Weatherstrip assembly (Сборка 691). Это полный, 7-тип, “cab-side” counterpart system for the ‘FAW Front Door’ (Сборка 683) на FAW Jiefang CA4251P66K24T1A3E5 6×4 трактор. Эта сборка является “логика” of the cab’s B-pillar, providing the three functions for a perfect door seal:

1. Фиксирующая логика: The Стопорное кольцо FAW (МГУ 4) provides the hardened steel “нападающий” for the door’s ‘Lock Body’ (689) to grab.

2. Логика выравнивания: The ‘Positioning Pin Seat’ (МГУ 2) обеспечивает “guide” to ensure the door aligns perfectly, preventing sag and rattles.

3. Логика уплотнения: The ‘Weatherstrip’ МГУ (1 & 7) provide the “прокладка” that the door compresses against to block wind and water.

This in-depth guide is essential for collision repair specialists and parts managers. Мы разберем всю Стопорное кольцо FAW сборка в свой 7 отдельная минимальная обслуживаемая единица (МГУ) типы. Мы проанализируем “compression latch” logic of the main ‘Locking Ring’ (the primary MSU), а “anti-sag” logic of the ‘Positioning Pin Seat’, а “dual-bulb” logic of the ‘Weatherstrips’, и критический, specialized fasteners that provide a safe, vibration-proof installation.

Основной 1: The “фиксация & Сжатие” Логика (МГУ 4, 5, 6) (The “дольше” Модуль)

This group of MSUs is the “безопасность” core of the assembly. Это “passive” side of the ‘Door Lock Mechanism’ (Сборка 689).

1. МГУ 4: ‘Locking ring assy’ (6105125-А01)

This is the primary MSU and the namesake of the Стопорное кольцо FAW сборка. It is the heavy-duty “нападающий” или “latch pin” that is mounted on the cab’s B-pillar. Его “логика” is to be the immovable “якорь” that the door’s ‘Lock Body’ (Сборка 689) rotary latch “captures.”

Строительство & Wear Logic: This is not a simple loop of steel. It is forged or cast from high-tensile, hardened steel to resist wear from millions of open/close cycles. It is also coated (НАПРИМЕР., zinc-plated) to be 100% нержавеющий. The “логика” of its design is critical: это “camming” поверхность.

Логика сжатия: When the ‘Lock Body’ (689) engages this Стопорное кольцо FAW, это “тянет” the door *past* its neutral point. Этот “тянет” action is the “логика” that creates “compression.” It actively squeezes the ‘Front Door Outer Weatherstrip’ (МГУ 1) тугой, creating the “bank vault” seal that blocks wind noise (ШВХ) и вода. A worn or misaligned Стопорное кольцо FAW это #1 cause of a “дребезжащий” или “leaky” door.

2. МГУ 5 & 6: The “Flush-Mount” Логика крепления

This is the specialized hardware for the Стопорное кольцо FAW. The system uses four (4) ‘Cross recessed countersunk head screws’ (Q2540825) и четыре (4) ‘Taper pin lock washers’ (Q41408).

Countersunk “Логика” (МГУ 5): The “логика” of using a “потайной” (flush-mount) screw is critical. The ‘Lock Body’ (689) on the door *must* pass over this area to engage the Стопорное кольцо FAW. A protruding hex-bolt head would “foul” или “варенье” the mechanism. These screws sit perfectly flush, creating a smooth “skid plate” for the latch.

Taper Lock “Логика” (МГУ 6): A countersunk screw cannot use a standard “spring washer.” The “логика” here is the ‘Taper pin lock washer’. This is a specialized “star washer” that is *also* cone-shaped. Его “зубы” are designed to “кусать” into the countersunk bevel of the screw (МГУ 5) *and* the metal of the cab’s B-pillar. Этот “biting” логика - это “антивибрационный” особенность, providing the essential locking tension to prevent this critical safety MSU from *ever* vibrating loose.

Основной 2: The “Выравнивание & ШВХ” Логика (МГУ 2 & 3)

This group of MSUs provides the “выравнивание” logic for the door, which is essential for the Стопорное кольцо FAW функционировать.

МГУ 2: '…Positioning Pin Seat’ (6101547-А01 / 6101548-А01): Это “женский” получатель. The ‘Front Door’ (683) имеет “male” guide pin. Этот “Сиденье” (МГУ 2) is the polymer-lined “дыра” that the pin slides into *before* the latch engages.

Логика выравнивания: Его “логика” это “guide” тяжелый, sagging door into *perfect* vertical alignment. This ensures the door’s ‘Lock Body’ (689) hits the Стопорное кольцо FAW (МГУ 4) *perfectly* every time, предотвращение “missed latches.”

NVH-логика: The polymer lining of this MSU also acts as a “buffer.” It provides a tight, “анти-погремушка” fit for the door pin, which prevents the door from vibrating, shaking, и “лязг” against the B-pillar on rough roads.

МГУ 3: ‘Болт с шестигранной головкой’ (Q1840612F6): Эти четверо (4) bolts are the “структурная логика” for the Pin Seat. Они высокопрочные, flanged bolts (со встроенной стиральной машиной) that securely anchor this critical alignment MSU to the cab’s frame.

Основной 3: The “Погода & Акустический” Логика (МГУ 1 & 7)

Эта последняя группа MSU является “логика герметизации” ассамблеи. They provide the “прокладка” что Стопорное кольцо FAW system compresses.

МГУ 1: '…Outer Weatherstrip Assy’ (6107015-А01 / 6107020-А01): This is the *primary* cab seal. Это большой, EPDM rubber “U-channel” that is mounted on the “pinch weld” of the *cab body* (the B-pillar).

Его “логика” это быть “dual-bulb” (hollow-core) тюлень. This design is a “логика” choice for superior NVH. The hollow “лампочка” compresses easily, предоставление а “мягкий” door close, while also creating a “double-wall” barrier that is exceptionally effective at blocking wind noise and water.

МГУ 7: ‘Front door upper weatherstrip’ (6107031-А01-С00): This is the *secondary* seal. The “логика” of this separate piece is that the “вершина” of the door frame has a different shape and “логика.” This MSU is not just a “лампочка” тюлень; it is often a “drip rail” тюлень, designed to actively *channel* water away from the ‘Side Window’ (634).

Both of these MSUs are critical wear items. When they crack or “набор сжатия” (flatten) with age, а Стопорное кольцо FAW (МГУ 4) can no longer create a tight seal, leading to wind noise and water leaks.
