فرامل العجلات المركزية FAW J6P: تفكيك 32 الأجزاء المهمة لقوة إيقاف لا تشوبها شائبة

هذا هو الدليل الفني الكامل ل فرامل العجلات المركزية FAW J6P (Model 3503025-A6E) لفاو جيفانغ CA3250P66K2L1T1E 6×4 تفريغ الشاحنة. هذا التفكيك يحلل 32 serviceable component types that form the complete S-cam brake assembly for the middle (إلى الأمام) drive axle.

ال فرامل العجلات المركزية FAW J6P هو واجب ثقيل, S-cam “drum” نظام الفرامل. This robust design is the industry standard for heavy-duty drive axles, prized for its durability, high stopping torque, and serviceability. Its primary function is to convert the kinetic energy of the 25-ton truck into heat, safely bringing the vehicle to a stop. It works by using compressed air to force a set of brake shoes and linings against the inner surface of the rotating brake drum.

This deconstruction will analyze the key serviceable assemblies of the فرامل العجلات المركزية FAW J6P, including the pneumatic actuator (air chamber), the mechanical linkage (S-cam and slack adjuster), the friction components (brake shoes and linings), and the stationary foundation (axle boss). تمت صيانتها بشكل صحيح فرامل العجلات المركزية FAW J6P is the most critical safety system on the tandem axles, and its condition is non-negotiable for safe operation. Every part of the فرامل العجلات المركزية FAW J6P must be inspected regularly.

جوهر 1: ال “Actuation” منطق (The Air Chamber)

هذا هو “عضلة” التابع فرامل العجلات المركزية FAW J6P. This component converts the pneumatic signal from the brake pedal into powerful mechanical force.

1. عنصر: ‘Center left brake air chamber assy’ (3530020-A0E) & ‘Center right’ (3530025-A0E)
هذا (شركات 32) is the complete air brake chamber. هذا هو “الفرامل الربيع” أو “piggyback” حَشد. ال Pneumatic-to-Mechanical Logic هي وظيفتها الأساسية: when the driver presses the brake pedal, compressed air fills the service chamber, pushing a rod out to apply the brakes.

ال Parking Brake Logic is the second function. A powerful internal spring is held compressed by constant air pressure. When the driver pulls the park brake, this air is released, and the spring mechanically expands, forcing the pushrod out and locking the فرامل العجلات المركزية FAW J6P. A leaking diaphragm in this chamber is a common failure point and will result in a dangerous air leak and a loss of braking power. هذا هو عنصر السلامة الحاسم في فرامل العجلات المركزية FAW J6P.

جوهر 2: ال “Foundation” منطق (The Brake Spider)

This group of components forms the stationary foundation of the فرامل العجلات المركزية FAW J6P. It bolts directly to the axle housing and serves as the anchor point for the brake shoes.

1. عنصر: ‘Left axle boss’ (3503127-A0E) – الكمية 1
هذا (شركات 10) هو “العنكبوت” أو “backing plate”. إنها ضخمة, single-piece cast iron component that bolts to the axle. إنه Anchor Point Logic is to absorb all the torque and forces generated by the braking action. The brake shoes (شركات 18) are anchored to this spider, and it is the component that the S-cam (شركات 3) passes through.

2. عنصر: "فاصل." – axle boss support’ (3502123-A0E) – الكمية 2
هذا (شركات 13) is a precision spacer used to properly position the axle boss on the axle housing, ضمان فرامل العجلات المركزية FAW J6P is perfectly aligned with the brake drum.

3. عنصر: ‘Rear brake dust pan’ (3502031-A0E) & ‘Front dust pan’ (3502032-A0E)
هذا (شركات 8 & 9) is the dust shield assembly. These thin metal plates bolt to the spider (شركات 10) and partially enclose the فرامل العجلات المركزية FAW J6P to protect the shoes and drum from contamination by rocks, الطين, وحطام الطرق, which is critical in a dump truck application.

جوهر 3: ال “Friction” منطق (The Brake Shoes & Linings)

هذا هو “يرتدي” جزء من فرامل العجلات المركزية FAW J6P. These components are designed to be sacrificed to create the friction needed to stop the truck.

1. عنصر: ‘Brake shoe with lining assy’ (3502375-A0E) – الكمية 4
هذا (شركات 18) is the complete brake shoe, which includes the steel “web” and the pre-riveted friction lining. ال فرامل العجلات المركزية FAW J6P uses two of these shoes (primary and secondary) per wheel.

2. عنصر: ‘Rear brake lining I’ (3502406-A0E) & ‘Rear brake lining II’ (3502407-A0E) – الكمية 4 كل
هذا (شركات 20, 21) is the serviceable friction material. ال منطق الاحتكاك involves two different lining types (I and II), which suggests a “leading/trailing” أو “primary/secondary” shoe design. One lining is more aggressive to provide the initial bite, while the other is designed for sustained friction and heat dissipation.

3. عنصر: ‘Rivet – brake lining’ (3502408-A0E) – الكمية 112
هذا (شركات 22) هي مجموعة من 112 rivets used to attach the ‘Brake linings’ (شركات 20, 21) to the steel brake shoe web. This riveted design is common in heavy-duty فرامل العجلات المركزية FAW J6P systems as it is strong and allows for the linings to be replaced.

4. عنصر: ‘Return spring’ (3502436-A0E) & ‘Anchor pin’ (3502398-A0E)
هذا (شركات 28, 27) is the retraction system. The heavy-duty ‘Return spring’ connects to the ‘Anchor pin’ (شركات 27) and aggressively pulls the brake shoes back away from the brake drum the instant the driver releases the pedal. A weak or broken return spring will cause the فرامل العجلات المركزية FAW J6P ل “يجر,” leading to extreme overheating and failure.

جوهر 4: ال “غش & Adjuster” منطق (The Actuation Linkage)

This group of components forms the mechanical link between the air chamber (جوهر 1) and the brake shoes (جوهر 3). It translates the linear push from the air chamber into a rotary motion that spreads the shoes apart. هذا هو قلب فرامل العجلات المركزية FAW J6P.

1. عنصر: ‘Left/Right slack adjuster assy’ (3503205-A0E, 3503210-A0E) – الكمية 1 كل
هذا (شركات 14) هو “الضابط الركود”. هذا Self-Adjusting Logic is a key feature of a modern فرامل العجلات المركزية FAW J6P. As the brake linings (شركات 20, 21) يرتدي, this device automatically adjusts its angle on the camshaft to ensure the “الركود” (distance) between the lining and the drum remains minimal. This provides a consistent, responsive brake pedal.

2. عنصر: ‘Left/Right rear brake camshaft’ (3502151-أ6ه, 3502152-أ6ه) – الكمية 1 كل
هذا (شركات 3) is the ‘S-cam’. This is a forged steel shaft with an “ق” shaped head at one end. As the slack adjuster (شركات 14) rotates this shaft, ال “ق” shape pushes against the ‘Brake shoe rollers’ (شركات 26), forcing the brake shoes apart and into the drum. This is the final mechanical force multiplication in the فرامل العجلات المركزية FAW J6P.

3. عنصر: ‘Camshaft bearing assy’ (3502135-A0E) & ‘Seals’ (3502153-A0E)
هذا (شركات 4, 5, 7) is the bearing and seal system for the camshaft. The camshaft must rotate smoothly within the axle boss (شركات 10). These ‘Bearings’ (شركات 4) and ‘Oil seals’ (شركات 5, 7) ensure a low-friction rotation and prevent water and grit from entering and seizing the فرامل العجلات المركزية FAW J6P عمود الحدبات.
