Модуль пневматического тормоза FAW в сборе: Комплексное внимание к 17 Критические компоненты

Добро пожаловать в это подробное техническое руководство по Модуль пневматического тормоза FAW в сборе (Сборка 542). Это полный, chassis-mounted pneumatic control and air storage system for the FAW Jiefang CA4251P66K24T1A3E5 6×4 дизельный полуприцеп тягач. Эта сборка является “power pack” for the truck’s entire braking system.

The Модуль пневматического тормоза FAW в сборе является а “логика” system that integrates multiple components. Its function is to safely store the high-pressure air generated by the compressor in the ‘Air storage tank assembly’ (3513055-91Вт) and to house the vehicle’s batteries on a single, безопасный, chassis-mounted bracket.

This in-depth guide is an essential resource for professional chassis technicians and fleet managers. Мы разберем всю Модуль пневматического тормоза FAW в сборе в свой 17 типы обслуживаемых компонентов, including the air tanks, the main ‘Air storage tank & battery bracket assy’ (3513800-91Вт), the ‘Drain valve’, and all the critical fittings and high-tensile fasteners that make this system safe and reliable.

Основной компонент: The ‘Air Storage Tank Assembly’ (3513055-91Вт)

Сердце Модуль пневматического тормоза FAW в сборе is the ‘Air storage tank assembly’ (3513055-91Вт), также известный как “air reservoir” или “air tank.” The parts list calls for two of these. These are heavy-duty, steel-walled cylinders designed to safely store compressed air at pressures exceeding 120 пси (8.3 bar).

Это “power supply” for the entire brake system. The “логика” of a pneumatic Модуль пневматического тормоза FAW в сборе is to have a large volume of pre-compressed air ready at all times. When the driver hits the brake pedal, it’s not their foot pressure doing the work; they are simply opening a valve that releases this massive, stored energy to the brake chambers.

These tanks must be in perfect condition. Через некоторое время, moisture from the air system can settle in the bottom, causing internal rust. This rust can flake off, travel down the Модуль пневматического тормоза FAW в сборе, and clog the sensitive brake valves. A heavily-rusted tank can, in a worst-case scenario, rupture under pressure, leading to a catastrophic and total loss of all braking power.

The “Логика”: Integrated Bracket (3513800-91Вт) and Drain Valves (3513100-1500)

The “логика” принадлежащий Модуль пневматического тормоза FAW в сборе is its integrated design. The ‘Air storage tank & battery bracket assy’ (3513800-91Вт) является основным “скелет” of the assembly. This is a complex, heavy-duty fabricated steel bracket that serves two purposes:

• It acts as the “cradle” that holds the two ‘Air storage tank assembly’ (3513055-91Вт) единицы, securing them to the chassis frame with ‘Tank strap assembly’ (3513095-91Вт).
• It also provides the housing and support for the truck’s main batteries via the ‘Battery cover plate’ (3513801-91Вт).

Этот “логика” of combining the air tanks and battery box into one module saves space on the chassis rail, a critical commodity on a modern tractor. The ‘Air storage tank bracket’ (3513081-91Вт) units are the individual mounts that are part of this main assembly.

The most important service “логика” on the Модуль пневматического тормоза FAW в сборе is the ‘Drain valve assembly’ (3513100-1500). There are two of these, one for each tank. Air from the compressor inevitably contains some moisture. This moisture condenses and settles at the bottom of the air tanks. The “логика” of the drain valve is to provide a simple, manual way to “drain” this corrosive water from the system daily, защита всего Модуль пневматического тормоза FAW в сборе from internal rust and freeze-up in cold weather.

Fittings and Service Ports

The Модуль пневматического тормоза FAW в сборе является запечатанным, high-pressure system that relies on a complex array of “арматура” (люверсы) and service ports. The parts list calls for a large quantity of these:

• «Втулка (M22) with sealing ring assy’ (3513410-1500) – 4 единицы
• «Втулка (M16) with sealing ring assy’ (3506410-1500) – 1 единица
• ‘Plug chamber (M16) with sealing ring assy’ (3506415-1500) – 1 единица

Это “порты” where the high-pressure nylon air lines (from Assembly 539) connect to the air tanks. The “grommet” design is a “push-to-connect” fitting, sealed with ‘Special-shaped sealing rings’ (3513403-1500, 3506403-1500) and held in place by ‘Circlips’ (3513407-1500, 3506407-1500). Этот “логика” allows for a fast, надежный, and field-serviceable connection. A failure of one of these O-rings or ‘Gasket rings’ (3513839-91Вт) will result in a “slow leak,” causing the air compressor to cycle constantly and potentially draining the Модуль пневматического тормоза FAW в сборе overnight.

The ‘Quick-connect test connector’ (T833) is a diagnostic “логика” port. It allows a technician to quickly connect a pressure gauge to the Модуль пневматического тормоза FAW в сборе to test the system pressure without having to disconnect a main line.

Critical Fasteners and Hardware

The Модуль пневматического тормоза FAW в сборе holds hundreds of pounds of steel (tanks and batteries) and is subjected to constant road vibration. Its fastener system is critical to its safety and function.

**Chassis Mounts:** The main ‘Air storage tank & battery bracket assy’ (3513800-91Вт) is secured to the truck’s frame with four ‘Hex head flange lock nuts’ (CQ32614) and four ‘Hex flange bolts’ (Q1841445T). The “фланец” и “lock nut” design is a “логика” choice to prevent loosening under vibration.

**Tank Mounts:** The ‘Air storage tank brackets’ (3513081-91Вт) are secured with ‘Hex head bolts’ (CQ1501025), ‘Hex nuts’ (CQ34010), и «Прокладки пружин’ (Q40310). The ‘Tank strap assembly’ (3513095-91Вт) is tightened with ‘Inner hex socket head cap screws’ (CQ2180870Q).

**Battery Mounts:** The ‘Battery cover plate’ (3513801-91Вт) is secured by ‘Locking clamps’ (3513837-91Вт, 3513837-2000), which are locked down with ‘Cotter pins’ (3513839-91Вт). Этот “приколоть” logic is a quick-release, yet positive-locking, mechanism that allows for battery service while ensuring the heavy batteries cannot escape. This entire hardware set is essential to the integrity of the Модуль пневматического тормоза FAW в сборе.
