Embreagem de ventilador FAW J6P: Desconstruindo 10 Peças críticas para uma lógica térmica perfeita

Welcome to this expert deconstruction of the Embreagem de ventilador FAW J6P conjunto, a critical component group for the FAW Jiefang CA3250P66K2L1T1E 6×4 caminhão basculante a diesel. This technical guide is engineered for service technicians, gestores de frota, e especialistas em peças. We will deconstruct the entire 10-component “lógica” group, breaking it down from the primary ‘Fan clutch assy’ to its smallest serviceable fasteners, providing a complete picture for diagnostics and maintenance.

The thermal management of the CA3250P66K2L1T1E is defined by this “inteligente” componente. O Embreagem de ventilador FAW J6P é o “cérebro” of the entire cooling fan system. Its sole logic is to intelligently engage the fan *only* when needed, saving fuel and horsepower, while ensuring the engine is perfectly protected under high-load, low-speed conditions.

Essencial 1: O “Smart Engagement” Lógica (The FAW J6P Fan Clutch)

Este grupo representa o cérebro of the entire cooling fan assembly. Its purpose is to intelligently and mechanically “decide” when to engage the fan, saving fuel, and when to lock it up for maximum cooling. This is the core logic of the Embreagem de ventilador FAW J6P.

1. Componente: ‘Fan clutch assy’ (1313010-65D)
Esse (Comp. 8) is the ‘Fan Clutch Assembly’ em si, the most critical and complex component in this breakdown. For this heavy-duty application, é um Viscous Clutch. This is a non-electric, thermomechanical device.

O Thermostatic Logic is how it “thinks.” A bi-metallic thermostatic spring is mounted on the very front of the Embreagem de ventilador FAW J6P. It sits directly in the air-path *after* the air has passed through the radiator. This allows it to read the true temperature of the cooling system.

As this air temperature rises (Por exemplo, above 85°C), the spring’s metals expand at different rates, causing it to coil or uncoil. This physical movement mechanically opens a small internal valve. Este é o Viscous Logic.

Opening this valve allows a special, high-viscosity silicone fluid, stored in a reservoir, to flow into a working chamber. This chamber contains intricate, alternating plates and fins—one set connected to the input shaft (driven by the engine pulley) and the other to the output body (which holds the fan).

O Fluid Shear Logic is what transfers power. O “cisalhar” of this thick fluid between the spinning plates is what transfers torque from the engine to the fan. The hotter the air, the more the valve opens, the more fluid enters the chamber, and the faster the fan spins. Isso é Progressive Engagement, not a simple on/off switch. This variable-speed capability is the key feature of the Embreagem de ventilador FAW J6P.

When the engine cools, the air from the radiator cools, the spring closes the valve, and an internal pump returns the fluid to the reservoir. This disengages the Embreagem de ventilador FAW J6P, allowing the fan to freewheel, saving horsepower and significantly improving fuel economy.

Essencial 2: O “Interface & Dirigir” Lógica (The Flange)

This group contains the critical adapter that connects the Embreagem de ventilador FAW J6P to the engine’s drive pulley. Its logic is to provide a secure, perfectly aligned mounting point and transfer 100% of the engine’s torque to the clutch.

1. Componente: ‘Fan clutch transition flange’ (1313063-14B)
Esse (Comp. 10) is the ‘Fan Clutch Transition Flange.’ It is the essential “Interface” componente. O Embreagem de ventilador FAW J6P (Comp. 8) is a specialized unit, but the engine’s pulley hub (often on the water pump) has its own standardized bolt pattern.

This ‘Transition Flange’ is the high-strength steel adapter that bridges this gap. It is precisely machined to bolt flat against the engine’s pulley hub (using the ‘Combination bolts’, Comp. 9) e, por sua vez, provide the exact mounting face and bolt pattern required by the Embreagem de ventilador FAW J6P.

O Concentricity Logic is its hidden, vital function. This flange must maintain perfect concentricity (zero “oscilar” ou “acabar”). Any misalignment would introduce destructive vibrations into the entire assembly, leading to premature failure of the Embreagem de ventilador FAW J6P rolamentos.

Essencial 3: O “Driven Component” Lógica (A Assembleia do Ventilador)

Este grupo representa o “carregar” que o Embreagem de ventilador FAW J6P is responsible for driving. Its logic is to convert the rotational energy it receives from the clutch into massive, high-velocity airflow.

1. Componente: ‘Fan assy’ (1308010-14B)
Esse (Comp. 4) is the ‘Fan Assembly’ em si. While not technically part of the Embreagem de ventilador FAW J6P, it is the component the clutch drives. É um serviço pesado, multi-blade unit made from high-strength composite or steel.

O Blade Pitch Logic é crítico: the specific angle and curvature of the blades are engineered to maximize airflow (CFM) while minimizing noise and the horsepower “arrastar” on the Embreagem de ventilador FAW J6P.

O Assembly Logic is a crucial service note: the ‘Fan assy’ é um único, factory-balanced component. It must be replaced as a whole if damaged. A bent blade will cause vibrations that will destroy the new Embreagem de ventilador FAW J6P it is attached to.

Essencial 4: O “Fixador Crítico” Lógica (All Hardware)

This final group is the most frequently overlooked. Isso é lógica is to manage extreme vibration, alto torque, and thermal cycling. Using generic hardware on a Embreagem de ventilador FAW J6P assembly is a direct cause of catastrophic failure.

1. O “Fan-to-Clutch” Grupo (Comp. 1, 2, 3)
This sub-assembly includes: 'Porca hexagonal’ (CQ34008, Quantidade 6), ‘Spring washer’ (Q40308, QVty 6), and ‘Washer’ (Q40108, Quantidade 6). Este é o Sandwich Logic used to mount the ‘Fan assy’ (Comp. 4) onto the front of the Embreagem de ventilador FAW J6P (Comp. 8).

O Máquina de lavar (Comp. 3) is a ‘flat washer,’ providing a wide surface to prevent cracking the fan material. O Arruela elástica (Comp. 2) is the most critical part, as it provides Anti-Vibration Pre-load, preventing the nuts from backing off under high-frequency vibration.

2. O “Clutch-to-Flange” Grupo (Comp. 5, 6, 7)
Este grupo inclui: ‘Stud bolt’ (CQ1201030, Quantidade 4), ‘Spring washer’ (Q40310, Quantidade 4), and ‘Hexagon nut’ (CQ34010, Quantidade 4). Este é o Serviceable Mount Logic for attaching the Embreagem de ventilador FAW J6P (Comp. 8) to the ‘Transition flange’ (Comp. 10).

The ‘Stud bolts’ (Comp. 5) are likely threaded permanently into the Embreagem de ventilador FAW J6P em si. This allows a technician to easily ‘hang’ the heavy clutch assembly onto the studs, freeing their hands to install the washers and nuts.

3. O “Flange-to-Engine” Grupo (Comp. 9)
Este grupo inclui: ‘Combination bolt’ (CQ1421040, Quantidade 6). Este é o Assembly Line Logic. A ‘combination bolt’ has a captive, free-spinning spring washer pre-installed. This feature makes installation faster and, more importantly, makes it *impossible* to forget the critical spring washer. These bolts secure the ‘Transition flange’ (Comp. 10) to the engine’s pulley hub, transferring all drive power to the Embreagem de ventilador FAW J6P.
