دواسة الفرامل مع صمام الفرامل: تفكيك 32 الأجزاء المهمة للتحكم في التوقف بشكل لا تشوبه شائبة

هذا هو التفكيك الفني الكامل لل دواسة الفرامل مع صمام الفرامل تجميع FAW Jiefang CA3250P66K2L1T1E 6×4 تفريغ الشاحنة. هذا الدليل تفاصيل 32 serviceable component types that form this critical driver-control module, which also integrates the clutch pedal assembly.

ال دواسة الفرامل مع صمام الفرامل assembly is the primary driver interface for the vehicle’s entire pneumatic braking system. On a heavy-duty truck, this is not just a simple mechanical pedal; it is an integrated module. The ‘Brake valve & joint assy’ (3514010-50أ) هو الرئيسي “foot valve,” which translates the driver’s foot pressure into a proportional pneumatic signal, controlling the air brakes. This deconstruction will also analyze the integrated clutch control system, including the ‘Clutch booster assy’ (1602110-76دبليو) and ‘Clutch oil cup’ (1602100-76دبليو), which share the same mounting bracket. A properly functioning دواسة الفرامل مع صمام الفرامل is the most critical safety component for driver control. We will explore every part of this دواسة الفرامل مع صمام الفرامل module.

جوهر 1: ال “Brake Valve” منطق (Pneumatic Control)

This group of components is the reason this assembly is called the دواسة الفرامل مع صمام الفرامل. إنه “مخ” of the service brake system, translating mechanical force into a precise pneumatic signal.

1. عنصر: ‘Brake valve & joint assy’ (3514010-50أ) – الكمية 1
هذا (شركات 15) هو الرئيسي “foot valve”. ال Proportional Valve Logic أمر بالغ الأهمية: when the driver presses the ‘Brake pedal’ (شركات 24), this valve opens to release compressed air from the tanks. It does not just open; it releases air *in proportion* to how hard the pedal is pressed. This allows the driver to “feather” the brakes or apply them gently, which is essential for vehicle control. A failure in this core valve would result in a total loss of service brakes. This is the heart of the دواسة الفرامل مع صمام الفرامل.

2. عنصر: ‘Brake light switch assy’ (3720010-أ01) – الكمية 1
هذا (شركات 18) is the electric switch mounted to the دواسة الفرامل مع صمام الفرامل حَشد. It is activated by the initial movement of the brake pedal, instantly illuminating the brake lights *before* significant air pressure is even applied. This is a critical safety feature.

3. عنصر: ‘Brake Pedal Assy’ (3504070-50أ) & ‘Pedal Pads’ (3504038-50أ, 3504037-50أ)
هذا (شركات 24, 21, 22) is the driver’s physical input. The ‘Brake pedal assy’ is the steel lever that pivots on the ‘Shaft-main’ (شركات 8). It is topped with rubber ‘Pedal pads’ for grip. This lever provides the mechanical advantage needed to activate the air valve. The design of the pedal and its pivot point are key to the feel of the دواسة الفرامل مع صمام الفرامل.

جوهر 2: ال “Clutch Control” منطق (Air-Assisted Hydraulic)

هذا دواسة الفرامل مع صمام الفرامل module is an integrated assembly that also houses the entire clutch pedal and booster system. This is a common design in heavy-duty trucks to save space.

1. عنصر: ‘Clutch oil cup assy’ (1602100-76دبليو) – الكمية 1
هذا (شركات 2) is the hydraulic fluid reservoir for the clutch. It holds the brake fluid that is used to actuate the clutch master cylinder, which is the start of the hydraulic clutch circuit.

2. عنصر: ‘Clutch booster assy’ (1602110-76دبليو) – الكمية 1
هذا (شركات 3) is the clutch master cylinder, but with a pneumatic booster. ال Air-Assist Logic is that this component uses compressed air (tapped from the brake system) to multiply the driver’s foot pressure. This makes the extremely heavy-duty clutch on the dump truck feel as light as a passenger car’s, تقليل التعب السائق. This pneumatic integration is why it is part of the دواسة الفرامل مع صمام الفرامل module.

3. عنصر: ‘Clutch pedal’ (1602037-50أ) & ‘Return spring’ (3504036-50أ)
هذا (شركات 9, 13) is the mechanical linkage for the clutch. The ‘Clutch pedal’ pivots on the same ‘Shaft-main’ (شركات 8) as the brake pedal. The ‘Return spring’ ensures the pedal returns to its upward position. ال دواسة الفرامل مع صمام الفرامل module uses a shared pivot.

4. عنصر: ‘Clutch switch assy’ (3754030-76دبليو) – الكمية 1
هذا (شركات 17) is an electronic switch activated by the clutch pedal. It serves as a safety interlock, preventing the engine from starting unless the clutch pedal is fully depressed. This is a critical safety feature integrated into the دواسة الفرامل مع صمام الفرامل حَشد.

جوهر 3: ال “تصاعد & Linkage” منطق (The Core Structure)

This group includes the central bracket and the shared pivot hardware that holds the entire دواسة الفرامل مع صمام الفرامل module together and mounts it to the cab’s firewall.

1. عنصر: ‘Pedal bracket’ (1602037-50أ, 3504031-76دبليو)
The ‘Clutch pedal’ (شركات 9) and ‘Pedal bracket’ (شركات 20) form the main structural housing. هذا الثقيل, stamped-steel bracket is the foundation that holds the main shaft, all pedals, the clutch booster, and the main air valve. It must be rigid to prevent flexing, which would cause a spongy pedal feel.

2. عنصر: ‘Shaft – main’ (1602091-50أ) – الكمية 1
هذا (شركات 8) is the common pivot shaft. Both the brake and clutch pedals pivot on this single shaft. It is supported by ‘Bushing – clutch pedal shaft’ (شركات 11, 3504061-50أ) to ensure a smooth, low-friction, and quiet operation.

3. عنصر: ‘Pedal shaft’ (3504032-50أ) & ‘Pedal bushing’ (3504074-50أ)
هذا (شركات 31, 32) is the hardware for the brake pedal itself. The ‘Pedal shaft’ is the pin that connects the brake pedal lever (شركات 24) to the plunger of the ‘Brake valve’ (شركات 15). The ‘Pedal bushing’ ensures this connection is tight and smooth. Any play in this specific part of the دواسة الفرامل مع صمام الفرامل would be felt by the driver as a “dead zone” in the pedal.
