Conjunto del módulo de freno neumático FAW: Un enfoque integral en 17 Componentes críticos

Bienvenido a esta completa guía técnica sobre el Conjunto del módulo de freno neumático FAW (Asamblea 542). este es el completo, chassis-mounted pneumatic control and air storage system for the FAW Jiefang CA4251P66K24T1A3E5 6×4 tractor semirremolque diésel. Esta asamblea es la “power pack” for the truck’s entire braking system.

El Conjunto del módulo de freno neumático FAW es un “lógica” 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’ (3513055-91W.) and to house the vehicle’s batteries on a single, seguro, chassis-mounted bracket.

This in-depth guide is an essential resource for professional chassis technicians and fleet managers. Deconstruiremos todo Conjunto del módulo de freno neumático FAW en su 17 tipos de componentes reparables, incluyendo los tanques de aire, the main ‘Air storage tank & battery bracket assy’ (3513800-91W.), the ‘Drain valve’, and all the critical fittings and high-tensile fasteners that make this system safe and reliable.

Componente central: The ‘Air Storage Tank Assembly’ (3513055-91W.)

El corazón de la Conjunto del módulo de freno neumático FAW is the ‘Air storage tank assembly’ (3513055-91W.), también conocido como el “air reservoir” o “air tank.” La lista de piezas requiere dos de estos.. Estos son resistentes, steel-walled cylinders designed to safely store compressed air at pressures exceeding 120 PSI (8.3 bar).

Este es el “power supply” for the entire brake system. El “lógica” of a pneumatic Conjunto del módulo de freno neumático FAW 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. Con el tiempo, moisture from the air system can settle in the bottom, causing internal rust. This rust can flake off, travel down the Conjunto del módulo de freno neumático FAW, and clog the sensitive brake valves. A heavily-rusted tank can, en el peor de los casos, rupture under pressure, leading to a catastrophic and total loss of all braking power.

El “Lógica”: Integrated Bracket (3513800-91W.) and Drain Valves (3513100-1500)

El “lógica” del Conjunto del módulo de freno neumático FAW is its integrated design. The ‘Air storage tank & battery bracket assy’ (3513800-91W.) es el principal “esqueleto” de la asamblea. This is a complex, heavy-duty fabricated steel bracket that serves two purposes:

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

Este “lógica” 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’ (3513081-91W.) units are the individual mounts that are part of this main assembly.

The most important service “lógica” en el Conjunto del módulo de freno neumático FAW 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. El “lógica” of the drain valve is to provide a simple, manual way to “drenar” this corrosive water from the system daily, protegiendo toda la Conjunto del módulo de freno neumático FAW from internal rust and freeze-up in cold weather.

Fittings and Service Ports

El Conjunto del módulo de freno neumático FAW es un sellado, high-pressure system that relies on a complex array of “guarniciones” (ojales) and service ports. The parts list calls for a large quantity of these:

• ‘Grommet (M22) con conjunto de anillo de sellado’ (3513410-1500) – 4 unidades
• ‘Grommet (M16) con conjunto de anillo de sellado’ (3506410-1500) – 1 unidad
• ‘Plug chamber (M16) con conjunto de anillo de sellado’ (3506415-1500) – 1 unidad

Estos son los “puertos” where the high-pressure nylon air lines (de la Asamblea 539) connect to the air tanks. El “grommet” design is a “empujar para conectar” adecuado, sealed with ‘Special-shaped sealing rings’ (3513403-1500, 3506403-1500) and held in place by ‘Circlips’ (3513407-1500, 3506407-1500). Este “lógica” allows for a fast, confiable, and field-serviceable connection. A failure of one of these O-rings or ‘Gasket rings’ (3513839-91W.) resultará en un “slow leak,” causing the air compressor to cycle constantly and potentially draining the Conjunto del módulo de freno neumático FAW overnight.

El 'Conector de prueba de conexión rápida’ (T833) es un diagnostico “lógica” puerto. It allows a technician to quickly connect a pressure gauge to the Conjunto del módulo de freno neumático FAW to test the system pressure without having to disconnect a main line.

Critical Fasteners and Hardware

El Conjunto del módulo de freno neumático FAW 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.

**Soportes de chasis:** The main ‘Air storage tank & battery bracket assy’ (3513800-91W.) is secured to the truck’s frame with four ‘Hex head flange lock nuts’ (CQ32614) and four ‘Hex flange bolts’ (Q1841445T). El “brida” y “tuerca de bloqueo” design is a “lógica” choice to prevent loosening under vibration.

**Tank Mounts:** The ‘Air storage tank brackets’ (3513081-91W.) are secured with ‘Hex head bolts’ (CQ1501025), ‘Hex nuts’ (CQ34010), y 'Juntas de resorte’ (Q40310). The ‘Tank strap assembly’ (3513095-91W.) is tightened with ‘Inner hex socket head cap screws’ (CQ2180870Q).

**Battery Mounts:** The ‘Battery cover plate’ (3513801-91W.) is secured by ‘Locking clamps’ (3513837-91W., 3513837-2000), which are locked down with ‘Cotter pins’ (3513839-91W.). Este “alfiler” 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 Conjunto del módulo de freno neumático FAW.
