Linha de freio FAW J6P: Desconstruindo 30 Peças críticas para uma potência de parada perfeita

This is an in-depth technical guide to the Linha de freio FAW J6P sistema, a critical safety network on the FAW Jiefang CA3250P66K2L1T1E 6×4 caminhão despejando. Esta desconstrução analisa o 30 primary serviceable components that form the complete pneumatic brake circuit, from the air compressor to the final brake hoses.

O Linha de freio FAW J6P system is a complex pneumatic network that powers the vehicle’s service brakes and parking brakes. Unlike a hydraulic system, this air brake system is engineered for the extreme demands of a heavy-duty dump truck, providing reliable stopping power under full load. O Linha de freio FAW J6P is responsible for generating, treating, storing, and distributing compressed air to all three axles, as well as the hand brake valve. Esta desconstrução analisará os principais conjuntos úteis do Linha de freio FAW J6P, including the air protection valve, the numerous pipe assemblies, and the various brackets and hoses. A leak-free and fully functional Linha de freio FAW J6P system is the most critical safety feature of the vehicle.

Essencial 1: O “Generation & Proteção” Lógica (The Air Source)

This group forms the heart of the Linha de freio FAW J6P sistema. It is responsible for generating compressed air, treating it, and protecting the different brake circuits from one another.

1. Componente: ‘Air pipe assy – air compressor to air dryer’ (3506210-56A & 3506215-Y494)
Esse (Comp. 15 & 30) is the first stage of the Linha de freio FAW J6P. This pipe carries hot, moist air from the engine-mounted air compressor to the air dryer (air processing unit). This line is often metal or reinforced for high temperatures.

2. Componente: ‘Four-circuit protection valve’ (3515014-8E) – Quantidade 1
Esse (Comp. 14) is arguably the most important safety device in the entire Linha de freio FAW J6P. O Circuit Protection Logic é crítico: this valve receives clean, dry air from the air dryer and splits it into four protected circuits (Por exemplo, freios dianteiros, freios traseiros, park brake, accessories). If one circuit fails (Por exemplo, a hose bursts), this valve seals it off, ensuring the other three circuits remain pressurized and functional.

3. Componente: ‘Shaped seal gasket – four-circuit’ (3515013-93) – Quantidade 2
Esse (Comp. 17) is the specialized gasket that seals the four-circuit protection valve, ensuring no leaks occur at this central distribution point. A failure here would compromise the entire Linha de freio FAW J6P sistema.

Essencial 2: O “Service Line” Lógica (Quadro & Axle Pipes)

This group represents the extensive network of pipes, mangueiras, and brackets that route compressed air from the protection valve (Essencial 1) to the individual wheel brakes. This is the main plumbing of the Linha de freio FAW J6P.

1. Componente: ‘Front air pipe assy’ (3506205-60A) & ‘Front brake hose assy’ (3506040-75A)
Esse (Comp. 5 & 18) is the circuit for the front axle. O ‘conjunto do tubo de ar frontal’ is the main rigid line, while the ‘Front brake hose’ is the flexible rubber hose that connects from the Quadro FAW J6P to the moving axle, allowing for steering and suspension travel.

2. Componente: ‘Pipe assy’ (3506100-14BJ) & ‘Rear air pipe assy’ (3506215-Y494)
Esse (Comp. 26 & 30) forms the main service line to the rear tandem axles. Este é um longo, complex pipe assembly that runs the length of the Quadro FAW J6P.

3. Componente: ‘Pipe Bracket’ & ‘Pipe Clamp’ (Various)
Esse (Comp. 6, 9, 10, 11, 22, 23, 25, 27, 28) is a large group of specialized brackets and clamps. O Vibration Protection Logic is essential for a Linha de freio FAW J6P. These brackets (Por exemplo, ‘Left/Right pipe bracket’, ‘Air pipe support bracket’) secure the air lines to the frame and chassis, preventing them from chafing, vibrando, or being struck by debris. A single failed bracket can lead to a chafed line and a critical air leak.

Essencial 3: O “Control” Lógica (Válvulas & Cab Interface)

This group of components controls the Linha de freio FAW J6P sistema, translating driver inputs (foot pedal and hand valve) into pneumatic signals.

1. Componente: ‘Hand brake valve assy’ (3508010-704) – Quantidade 1
Esse (Comp. 19) is the driver-operated park brake valve in the cab. It controls the application and release of the powerful spring brakes on the rear axles. This is a primary control for the Linha de freio FAW J6P.

2. Componente: ‘Cab pipe assy (Style drawing)’ (3506300-96U) – Quantidade 1
Esse (Comp. 20) is the bundle of air lines that runs from the chassis up to the cab. It carries supply air *to* the hand brake valve (Comp. 19) and the foot valve (Comp. 21), and carries the “sinal” air *back down* to the brake system.

3. Componente: ‘Brake base plate & slack adjuster assy’ (3504020-76C) – Quantidade 1
Esse (Comp. 21) is the main foot valve assembly, mounted to the cab floor. When the driver presses the brake pedal, this valve opens and sends a proportional amount of air pressure through the Linha de freio FAW J6P to all service brakes.

4. Componente: ‘Pneumatic valve module assy’ (3513010-Y494) – Quantidade 1
Esse (Comp. 29) is a complex module, likely a relay valve or ABS modulator. O Relay Logic is that this valve receives a low-volume “sinal” from the driver’s foot valve and opens to deliver a high-volume, high-pressure blast of air from a nearby reservoir directly to the rear brake chambers. This eliminates the “lag” that would occur if the air had to travel all the way from the cab, making the Linha de freio FAW J6P responsivo.
