مولد فاو: دليل الخبراء لها 3 المكونات الرئيسية

مرحبًا بك في هذا الدليل الفني المتخصص حول مولد فاو حَشد (الجزء لا. 3701010-36د), the core of the electrical power system for the FAW Jiefang CA4251P66K24T1A3E5 6×4 جرار نصف مقطورة ديزل. This component is essential for all vehicle operations.

ال مولد فاو, technically an AC (Alternating Current) Generator or “المولد,” is a high-output component responsible for two critical tasks: it recharges the truck’s batteries and provides all the electrical power needed to run the engine’s ECU, حاقنات الوقود, إضاءة, التدفئة والتهوية وتكييف الهواء, and all other onboard electronics.

يعد هذا الدليل مصدرًا أساسيًا للفنيين المحترفين ومديري الأساطيل. Although the parts list is simple, it represents a complex system. سنقوم بتفكيك الكل مولد فاو حَشد, its internal logic, and its critical mounting hardware, وصولاً إلى أصغر وحدة صالحة للخدمة.

المكون الأساسي: The AC Generator Assembly (3701010-36د)

The main component is the ‘AC Generator Assembly’ (3701010-36د), وهو الكامل مولد فاو وحدة. هذا هو واجب ثقيل, high-amperage alternator (محتمل 100 amps or more at 24 فولت) specifically designed for the demands of a commercial tractor. Its function is to convert mechanical energy from the engine’s serpentine belt into usable DC electrical energy.

ال مولد فاو is not a simple motor. It operates by spinning an electromagnet (the **Rotor**) inside a fixed set of wire coils (the **Stator**). As the engine spins the generator’s pulley, the magnetic field of the rotor “cuts” across the stator windings, inducing an Alternating Current (تكييف) in the stator. This AC is the raw power generated by the unit.

This AC is not usable by the truck’s 24-volt DC system. لذلك, ال “منطق” التابع مولد فاو lies in its two internal electronic components: the rectifier and the voltage regulator. These components are typically housed inside the rear cover of the مولد فاو حَشد.

المنطق الداخلي: The Rectifier and Voltage Regulator

جزء رئيسي من مولد فاو assembly is the **Rectifier Bridge**. This is a solid-state electronic component, typically a set of six or more high-power diodes. These diodes act as one-way electrical valves. They capture the AC sine wave from the stator windings (which swings from positive to negative) و “نقف” the negative half, converting the entire output into a pulsating Direct Current (العاصمة). This DC is what is sent to the battery and the rest of the truck.

The **Voltage Regulator** is the “مخ” التابع مولد فاو. The truck’s electrical system is extremely sensitive and demands a constant voltage (على سبيل المثال, ~28.4 volts for a 24V system) to safely charge the batteries and power the ECU. لكن, ال مولد فاو‘s output is directly tied to engine speed; it produces less voltage at idle and far too much at high RPM.

The regulator solves this. It constantly monitors the battery voltage. If the voltage drops below the target (على سبيل المثال, 28.4الخامس), the regulator sends *more* electrical current to the spinning rotor via a set of “slip rings” و “brushes.” This makes the rotor’s electromagnet *stronger*. A stronger magnetic field induces more power in the stator, and the voltage rises.

على العكس من ذلك, if the voltage climbs *above* the target, the regulator sends *less* current to the rotor. The electromagnet weakens, less power is induced, and the voltage drops. This constant feedback loop, happening hundreds of times per second, is what provides the stable, “regulated” الجهد االكهربى. A failure in the regulator is a common reason for replacing a مولد فاو, as it can lead to dead batteries (under-charging) or a fried ECU (over-charging).

نظام التركيب: البراغي (3701327-36د) and Nuts (CQ32610)

قائمة الأجزاء ل مولد فاو assembly details its mounting hardware. This is a critical system, as the generator is a heavy component that is under a constant, high-tension side-load from the serpentine belt.

"الترباس." – لتثبيت مولد التيار المتردد’ (3701327-36د), منها اثنان, are the main fasteners. On a heavy-duty مولد فاو, this is often a “stud” نظام. These studs are threaded into the engine’s main mounting bracket. The generator is then slid onto these studs.

"صامولة قفل شفة الرأس السداسية."’ (CQ32610) is the key to securing the مولد فاو. The list calls for two nuts, matching the two studs. These are not simple nuts; they are **flange lock nuts**.

**شفة:** The base of the nut is “ذات حواف,” meaning it has a wide, غسالة متكاملة. This washer distributes the clamping force over a wider area of the مولد فاو‘s aluminum mounting ears, منعه من التشقق.

**قفل:** The nut is a “قفل الجوز,” meaning it is “prevailing-torque.” It is either “top-lock” (distorted at the top) أو “إدراج النايلون” (though less common in high-heat areas). This design means the nut actively resists backing off from the intense vibration of the diesel engine. A standard nut would vibrate loose, causing the مولد فاو to lose belt tension and stop charging.

This robust stud-and-lock-nut system is what allows the مولد فاو to be securely mounted, but also allows it to pivot on one of the bolts, which is necessary for setting the proper serpentine belt tension.
