Задняя облицовочная панель в сборе: Деконструкция 4 Важные детали для максимальной защиты кабины

Добро пожаловать на этот важный анализ Задняя облицовочная панель в сборе для FAW Jiefang CA3250P66K2L1T1E 6×4 самосвал. Это руководство деконструирует 4 critical serviceable units. This assembly is not just cosmetic; it is a vital engineered system for cab protection, airflow management, and vibration damping.

The Задняя облицовочная панель в сборе serves a multi-functional role on this heavy-duty dump truck. The area behind the cab is a high-impact zone, constantly subjected to debris, spillage, and high-frequency vibration. This guide breaks down how the assembly is constructed from its four key parts: the main panel, two types of damping blocks, and the serviceable clips.

Основной 1: The Structural Shell Logic (The Main Panel)

This component represents the primary structure and visual face of the Задняя облицовочная панель в сборе. It is the largest piece and serves as the foundation upon which all other components are mounted.

1. Компонент: ‘Rear cladding panel’ (5602011-Б35) – Кол-во 1
Этот (Комп 3) является основным компонентом, or the main panel itself. Its singular quantity confirms it is the main structural shell. Это сингл, large-format molding, likely from a high-impact, fiber-reinforced polymer.

The Protection Logic is its primary function. This panel shields the driver’s cab from high-velocity debris like stones, грязь, and gravel. On the CA3250P66K2L1T1E, this part is essential for maintaining cab integrity, снижение шума, and protecting the cab’s painted finish from abrasion.

The Aerodynamic and Purity Logic is also critical. This ‘Rear cladding panel’ helps smooth the airflow between the cab and the dumper body. This reduces turbulence and minimizes the amount of dirt drawn onto the chassis, air lines, and wiring, which is a key maintenance benefit of a properly-installed Задняя облицовочная панель в сборе.

The Service Logic dictates this part is a “replace-on-impact” элемент. Due to its composite construction, significant cracks are not repaired. It is designed to be replaced as a single unit. Its strength is derived from its molded shape, which includes ribs and bosses on the reverse side where the other components attach.

Основной 2: The Vibration Damping Logic (The Spacer Blocks)

This group of components is arguably the most critical for the longevity of the Задняя облицовочная панель в сборе. These are not simple spacers; they are engineered damping blocks.

1. Компонент: ‘Spacer block for rear cladding A’ (5702061-Б27) – Кол-во 1
Этот (Комп 1) is a primary, specialized locating block. The ‘A’ designation and single quantity imply it sets the main position of the assembly.

2. Компонент: ‘Spacer block – top cover middle panel’ (5702028-А02) – Кол-во 8
Этот (Комп 2) has a high quantity (8), showing these are the primary load-bearing and damping points, distributed across the panel.

The Damping Logic is the most important concept here. A 6×4 dump truck operates in an environment of severe vibration. Двигатель, unpaved roads, and hydraulic shocks transmit forces through the frame. If the panel were bolted directly, it would rattle and fatigue-fracture.

Эти 9 total blocks (Комп 1 + Комп 2) are made from high-density EPDM rubber. Their function is to “float” the main panel, creating a buffer that absorbs and dissipates these vibrations. They isolate the panel from the cab, which is the only way the Задняя облицовочная панель в сборе can survive its intended service life.

The Failure and Service Logic makes these critical wear items. Через некоторое время, УФ-свет, нагревать, and ozone will cause these blocks to harden and crack. The primary symptom of failure is a rattling sound.

Technicians should not simply tighten the assembly; this will transfer the vibration and break the panel. The correct procedure is to replace all 9 spacer blocks to restore the original damping. The distinction between the single ‘A’ block and the eight ‘middle’ blocks is crucial for correct reassembly.

Основной 3: The Fastening & Сервисная логика (The Clips)

This final component type holds a specific part of the Задняя облицовочная панель в сборе вместе. Its design is based on serviceability in a harsh environment.

1. Компонент: ‘Clip – top cover panel’ (5702028-А01) – Кол-во 7
Этот (Комп 4) is the ‘Clip’. The name is deliberate. It is not a bolt, винт, or rivet. Количество 7 suggests a secure, multi-point fastening system for a sub-panel.

The Serviceability Logic is the key reason for using clips. На самосвале, bolts and screws exposed to mud, вода, and salt will rust and seize. These clips (5702028-А01) are designed for rapid, low-effort removal. They are likely “push-pin” clips made of nylon, which does not corrode.

This allows a technician to quickly remove the ‘top cover panel’ to access components hidden behind the Задняя облицовочная панель в сборе, such as cab vents, wiring, or air lines.

The Sacrificial Logic is also a factor. These inexpensive clips are designed to be the “weak link.” In a minor impact, the clips are designed to break or pop out. Этот “жертвенный” failure saves the much more expensive ‘Rear cladding panel’ (Комп 3) from being cracked or destroyed.

During any service, it is best practice to replace any removed clips with new ones (Часть №. 5702028-А01) to ensure a tight, посадка без дребезжания. Повторное использование старых, fatigued clips is a common cause of failure.
