فرامل العجلات الأمامية فاو J6P: تفكيك 30 الأجزاء المهمة لقوة إيقاف لا تشوبها شائبة

This is a complete technical guide to the فرامل العجلات الأمامية فاو J6P (نموذج 3501015-901 / 3501020-901) لفاو جيفانغ CA3250P66K2L1T1E 6×4 تفريغ الشاحنة. This deconstruction analyzes 30 serviceable component types that form the complete S-cam brake assembly, a critical system for vehicle safety.

ال فرامل العجلات الأمامية فاو J6P هو واجب ثقيل, S-cam “drum” نظام الفرامل. This robust design is the industry standard for heavy-duty trucks, prized for its durability, high stopping torque, and field 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 does this by using compressed air, supplied by the brake line system, 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 الأمامية فاو 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 (brake spider). A properly maintained فرامل العجلات الأمامية فاو J6P is the most critical safety system on the front axle, and its condition is non-negotiable for safe operation.

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

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

1. عنصر: ‘Front brake air chamber assy’ (3519110-95أ) – الكمية 2
هذا (شركات 1) is the complete air brake chamber. ال Pneumatic-to-Mechanical Logic is its function: when the driver presses the brake pedal, compressed air fills this chamber, pushing on a large rubber diaphragm. This diaphragm is connected to a pushrod, which extends out of the chamber with significant force. This is the initial force that actuates the entire فرامل العجلات الأمامية فاو J6P.

A leaking diaphragm in this chamber is a common failure point and will result in a dangerous air leak and a significant loss of braking power on that wheel. This makes the air chamber a critical safety component of the فرامل العجلات الأمامية فاو J6P.

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

This group of components forms the stationary foundation of the فرامل العجلات الأمامية فاو J6P. It bolts directly to the steering knuckle and serves as the anchor point for the brake shoes.

1. عنصر: ‘Left/Right brake spider’ (3501151C242, 3501152C242) – الكمية 1 كل
هذا (شركات 5) هو “spider” أو “backing plate”. It is a massive, single-piece cast iron or forged steel component. إنه Anchor Point Logic is to absorb all the torque and forces generated by the braking action. The brake shoes (شركات 22) are anchored to this spider, and it is the component that the S-cam (شركات 15) passes through.

2. عنصر: ‘Left/Right brake spider support’ (3501021C242, 3501022C242) – الكمية 1 كل
هذا (شركات 7) is the support bracket that adapts the spider (شركات 5) to the steering knuckle. كامل فرامل العجلات الأمامية فاو J6P assembly is rigidly bolted to the axle via this bracket.

3. عنصر: ‘Left/Right brake camshaft support’ (3501127C242, 3501128C242) – الكمية 1 كل
هذا (شركات 8) is a supplementary bracket that supports the S-camshaft. This ensures the camshaft cannot flex under load, which would cause uneven brake application. This is a key part of the فرامل العجلات الأمامية فاو J6P‘s heavy-duty design.

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

هذا هو “wear” جزء من فرامل العجلات الأمامية فاو J6P. These components are designed to be sacrificed to create the friction needed to stop the truck.

1. عنصر: ‘Front brake shoe assy’ (3501390C242) – الكمية 4
هذا (شركات 22) is the complete brake shoe, which includes the steel “web” and the friction lining. ال فرامل العجلات الأمامية فاو J6P uses two of these shoes (primary and secondary) per wheel.

2. عنصر: ‘Brake lining I’ (3501406C242) & ‘Brake lining II’ (3501407C242) – الكمية 4 كل
هذا (شركات 23, 24) is the serviceable friction material. ال Friction Logic 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’ (3502408BA2T) – الكمية 56
هذا (شركات 25) is the set of rivets used to attach the ‘Brake linings’ (شركات 23, 24) to the steel brake shoe. This riveted design is common in heavy-duty فرامل العجلات الأمامية فاو J6P systems as it is strong and allows for the linings to be replaced.

4. عنصر: ‘Left/Right brake shoe with lining assy’ (3501375C242, 3501380C242)
هذا (شركات 21) is a pre-assembled unit, providing the complete shoe and lining (شركات 22) as a single part for easier service of the فرامل العجلات الأمامية فاو J6P.

جوهر 4: ال “S-Cam & 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.

1. عنصر: ‘Left/Right automatic slack adjuster assy’ (3501205C242, 3501210C242) – الكمية 1 كل
هذا (شركات 30) هو “slack adjuster”. هذا Self-Adjusting Logic is a key feature of a modern فرامل العجلات الأمامية فاو J6P. As the brake linings (شركات 23, 24) wear, this device automatically adjusts its angle on the camshaft to ensure the “slack” (distance) between the lining and the drum remains minimal. This provides a consistent, responsive brake pedal.

2. عنصر: ‘Front brake camshaft’ (3501082-4ه) – الكمية 4
هذا (شركات 15) is the ‘S-cam’. This is a forged steel shaft with an “ق” shaped head at one end. As the slack adjuster (شركات 30) 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 الأمامية فاو J6P. Section 17: ‘Lock washer – steering knuckle spindle nut’ (2)

3. عنصر: ‘Return spring – brake shoe’ (3501436-4ه) – الكمية 2
هذا (شركات 20) is a heavy-duty spring. إنه Return Logic is to aggressively pull the brake shoes (شركات 22) back away from the brake drum the instant the driver releases the pedal. A weak or broken return spring will cause the brakes to “drag,” leading to extreme overheating and failure of the فرامل العجلات الأمامية فاو J6P.
