Блокировка пола FAW: The 7 Необходимые MSU для тишины, Кабина без ржавчины

Добро пожаловать в это важное руководство по Блокировка пола FAW сборка. This is the complete 30-piece kit of engineered seals, люверсы, and plugs for the FAW Jiefang CA4251P66K24T1A3E5 6×4 трактор. These components are not cosmetic; they are a critical first-line defense for the cab’s integrity. Their core “логика” is to create a hermetic, “triple-threat” seal for the cab’s floor pan, protecting the driver and the vehicle from noise, вода, и дымит.

The Блокировка пола FAW system is a foundational component of the cab’s Noise, Вибрация, и жесткость (ШВХ) упаковка. The “логика” of this kit is to permanently seal the various access and drainage holes left in the sheet metal during the manufacturing (stamping, e-coating) процесс. Leaving these holes open would allow a direct path for engine noise, road spray, and dangerous exhaust gases to enter the cab.

This in-depth guide is a vital resource for body shop technicians, специалисты по столкновениям, и менеджеры по запчастям. Мы разберем всю Блокировка пола FAW kit into its 7 отдельная минимальная обслуживаемая единица (МГУ) типы. We will analyze the material science, the multi-functional sealing “логика,” and the specific location logic for each of the 30 куски.

The “Тройное уплотнение” Логика: Шум, Вода & Fume Barrier

The Блокировка пола FAW assembly is not about aesthetics; it is about “sealing logic.” A single missing plug can compromise the entire cab environment. This 30-piece kit provides three critical barrier functions.

1. Acoustic Sealing (NVH-логика):

The primary “логика” is to block noise. The cab sits directly over the engine, передача инфекции, and road. A single un-plugged hole acts as a “sound leak,” allowing low-frequency engine drone and high-frequency tire/wind hiss to enter the cab. This noise dramatically increases driver fatigue.

Эти Блокировка пола FAW plugs are made from dense, heavy EPDM rubber. They function as “acoustic dampers,” a key part of the ‘Soundproofing Pad’ система (Сборка 623). They have the mass to block and reflect sound waves, ensuring the cab remains quiet.

2. Вода & Corrosion Sealing Logic:

Это “логика” of longevity. The front tires constantly spray water, грязь, and corrosive road salt against the underside of the cab. If a plug is missing, this moisture is injected *under* the cab’s floor covering.

This trapped moisture saturates the sound deadening pads, which acts like a sponge against the bare metal floor. Это #1 cause of cab floor rust-out, which rots the cab from the inside. A single missing Блокировка пола FAW plug can destroy a floor pan.

3. Дым & Air Sealing Logic:

Это основной “safety logic.” The plugs on the firewall (‘Front Panel’) and transmission tunnel are a gas-tight seal. They prevent deadly, odorless Carbon Monoxide (CO) fumes from a potential exhaust leak from entering the driver’s breathing space.

This seal also stops drafts, пыль, and hot/cold air. Этот “логика” is key to HVAC efficiency. By sealing these leaks, а Блокировка пола FAW kit ensures the A/C and heater can maintain temperature without running constantly, saving fuel.

Материал & Логика проектирования: ЭПДМ резина

The Блокировка пола FAW plugs are not made from simple plastic. They are high-tech MSUs made from a specific material: ЭПДМ (Этилен-пропилен-диеновый мономер) резина.

Материальная логика: EPDM is the “логика” choice for this hostile environment.

• Temperature Resistance: It will not get brittle and crack at -40°C, and it will not melt or get soft at +120°C from exhaust heat.
• Chemical Resistance: It is highly resistant to water, дорожная соль, масло, diesel fuel, and brake fluid.
• Ozone/UV Resistance: The plugs on the firewall are exposed to engine bay ozone and UV light. EPDM will not crack or dry-rot like natural rubber.

Логика проектирования: These MSUs are designed for a one-way, “push-in” установка. Each plug features a deep “groove” around its circumference. The “логика” is that the plug is pushed through the sheet metal hole until the metal “щелкает” into this groove. This creates a 360-degree, “interference fit” that is both waterproof and vibration-proof, ensuring the plug *cannot* be shaken loose.

Деконструкция 7 MSU Types (The “дольше” Модуль)

The Блокировка пола FAW kit contains 7 distinct part numbers (МГУ), итого 30 куски. Этот “логика” of having so many types is for precision. Each plug is precision-molded to fit a *specific* hole’s shape and diameter.

МГУ 7: Firewall Plugs (Кол-во 2)

The ‘Round plug C-front panel’ (5302808-А01) is designed for the “передняя панель” (firewall). These two plugs seal holes in the vertical wall separating the driver from the engine.

МГУ 1-6: Floor Pan Plugs (Кол-во 28)

Эти 28 plugs are the main components of the Блокировка пола FAW набор, and they seal the horizontal floor of the cab. They are grouped by shape.

Round Plugs (МГУ 1, 4, 5):

• ‘Hole plug B’ (5109566-А95) – Кол-во 2
• ‘Round plug D-floor’ (5109614-А01) – Кол-во 2
• ‘Round plug B-floor’ (5109617-А01) – Кол-во 2

Oblong Plugs (МГУ 2, 3, 6):

• ‘Oblong plug B-floor’ (5109612-А01) – Кол-во 12
• ‘Oblong plug D-floor’ (5109613-А01) – Кол-во 9
• ‘Oblong plug C-floor’ (5109619-А01) – Кол-во 1

Each of these 7 part numbers is a distinct MSU. When servicing a cab (НАПРИМЕР., replacing the ‘Floor Insulation Underlay’), it is critical to inspect for any missing or damaged plugs. Each missing plug must be replaced with the *exact* part number to ensure a perfect “interference fit” тюлень.
