Вторичное уплотнение передней двери: Деконструкция 2 Важные детали для безупречной защиты окружающей среды

This technical guide provides a detailed deconstruction of the Вторичное уплотнение передней двери сборка для FAW Jiefang CA3250P66K2L1T1E 6×4 самосвал. This component is a crucial element in the vehicle’s “dual-seal” cab system. Мы проанализируем 2 critical parts, the seal itself and its mounting structure, to understand its role in weatherproofing.

The Вторичное уплотнение передней двери, also known as a door-mounted seal, works in conjunction with the primary (body-mounted) seal. Its core logic is to create a “second line of defense” against the elements. Positioned on the door itself, it seals against the cab’s inner flange, creating an air-gap “dead zone.” This system is vital for preventing water, пыль, and wind noise from entering the cab, especially in the extreme conditions faced by a CA3250P66K2L1T1E truck.

Основной 1: The “Dual-Zone Sealing” Логика (The Seal Itself)

This first component is the functional core of the assembly. It is the part that actively creates the seal, and it is provided as two distinct parts for the left and right sides of the vehicle.

1. Компонент: ‘Left front door secondary seal’ (6107061-A01-C00) – Кол-во 1
2. Компонент: ‘Right front door secondary seal’ (6107062-A01-C00) – Кол-во 1
These two part numbers constitute the complete set of the Вторичное уплотнение передней двери for the vehicle.

The Door-Mounted Logic is the first key principle. Unlike the primary seal (which is on the cab body), этот Вторичное уплотнение передней двери is attached directly to the perimeter of the door itself. This design is critical. It means the seal travels *with* the door, ensuring it is never scuffed, разорванный, or dislodged by personnel entering or exiting the cab.

The Profile and Material Logic is similar to other high-grade automotive seals. This component is made from a durable EPDM (Этилен-пропилен-диеновый мономер) резина. This material provides exceptional resistance to ozone, UV light, and temperature extremes, preventing it from cracking or hardening over time.

Its profile typically features a hollow “bulb” section. This is the part that compresses against the cab body’s inner metal flange when the door is closed. This compression creates the airtight and watertight barrier. The hollow design allows it to compensate for minor misalignments and to absorb the shock of a door slam, preventing a harsh “лязг” and contributing to a quieter cab.

The Acoustic Damping Logic is the secondary, but equally important, function of the Вторичное уплотнение передней двери. By creating a second, separate seal, it forms an “acoustic dead zone” in the channel between the primary seal and the secondary seal.

This trapped air gap is highly effective at disrupting and absorbing sound waves, particularly high-frequency wind noise. Этот “dual-seal” system is a hallmark of modern cab design, drastically reducing driver fatigue by creating a much quieter working environment. This is a key feature for the FAW Jiefang CA3250P66K2L1T1E.

Installation of the Вторичное уплотнение передней двери (6107061-A01-C00 or 6107062-A01-C00) typically involves a series of pre-installed clips or a press-fit channel that engages with a groove or holes on the door’s inner structure.

Основной 2: The “Structural Foundation” Логика (The Door Assembly)

This second group of components is not part of the seal itself, but represents the foundational structure to which the Вторичное уплотнение передней двери монтируется. A seal cannot function without a precise, rigid, and correctly shaped base.

1. Компонент: ‘Left front door welded assy’ (6100055-Б27) – Кол-во 1
2. Компонент: ‘Right front door welded assy’ (6100060-Б27) – Кол-во 1

The Mounting Flange Logic is the most important concept here. The ‘Left front door welded assy’ (6100055-Б27) is not just a flat panel. Its inner perimeter is stamped and formed into a precise channel or flange. This flange is the “отслеживать” that the Вторичное уплотнение передней двери is designed to follow.

The shape, curvature, and angle of this flange are all critical. They are engineered in tandem with the seal’s profile to ensure that when the Вторичное уплотнение передней двери установлен, it is held at the perfect angle and position. This ensures that the seal’s bulb compresses uniformly against the cab body.

The Логика жесткости is also key. The ‘Right front door welded assy’ (6100060-Б27) is a large, structurally rigid component. This rigidity is essential to the sealing system. The door must not flex or twist during vehicle operation, even on rough terrain.

If the door frame were to flex, it would create gaps between the Вторичное уплотнение передней двери and the cab body, instantly compromising the seal and allowing noise, вода, and dust to enter. The ‘welded assy’ provides the robust, stable platform necessary for the soft, flexible seal to do its job effectively.

Поэтому, а Вторичное уплотнение передней двери assembly is a system of two parts: the soft, flexible seal (Основной 1) and the hard, rigid door structure (Основной 2). They are listed together in this breakdown because one cannot be serviced or understood without the other.

A technician replacing a worn Вторичное уплотнение передней двери must first inspect the door’s mounting flange (part of 6100055-B27 or 6100060-B27) for any damage, ржавчина, or deformation. A bent flange will prevent even a brand new seal from functioning correctly.
