Sous-couche d'isolation de sol FAW J6P: Déconstruction 5 Pièces critiques pour une isolation parfaite de la cabine

This is a concise technical guide to the Sous-couche d'isolation de sol FAW J6P assemblage pour le FAW Jiefang CA3250P66K2L1T1E 6×4 tombereau. Cette déconstruction analyse 5 types de composants réparables, detailing the multi-piece thermal and acoustic pads and their securing hardware.

Le Sous-couche d'isolation de sol FAW J6P system is a critical comfort and protective component in the cab structure. Its primary function is two-fold: thermally, it insulates the cab floor from the high temperatures generated by the engine and transmission, and acoustically, it dampens road and drivetrain noise. This insulation is placed directly beneath the primary floor mats and carpet components, forming a high-density barrier.

The multi-piece design of the Sous-couche d'isolation de sol FAW J6P—covering the left, right, and center transmission tunnel—allows for precise fitment around the various pedals, harnais de câblage, and seat mounts. This deconstruction will analyze the three main insulation pads and the specific fastening system used to anchor the entire assembly securely. A properly fitted Sous-couche d'isolation de sol FAW J6P is essential for driver comfort, preventing heat-related fatigue and reducing cabin noise levels significantly.

Cœur 1: Le “Thermal & Acoustique” Logique (The Pads)

This group of components provides the dense material barrier that is the functional core of the Sous-couche d'isolation de sol FAW J6P système.

1. Composant: ‘Left floor insulation pad’ (5109311-B35) – Quantité 1
Ce (Comp 1) covers the main driver-side floor area. Le Thermal Barrier Logic requires this pad to have a high R-value (insulation rating) to block engine and exhaust heat from transferring into the cab, which is a major comfort factor in the **FAW J6P Floor Insulation Underlay**.

2. Composant: ‘Right floor insulation pad’ (5109312-B35) – Quantité 1
Ce (Comp 2) covers the passenger-side area. These are pre-cut components, designed to perfectly match the contours of the cab floor pan, minimizing gaps that would allow noise or heat transfer.

3. Composant: ‘Center floor insulation pad’ (5109313-B35) – Quantité 1
Ce (Comp 3) is designed to cover the high transmission tunnel. This area is the highest source of heat and noise and thus requires the most dense insulation. The secure placement of this center mat is critical for the full acoustic performance of the Sous-couche d'isolation de sol FAW J6P.

Cœur 2: Le “Retention” Logique (Matériel de montage)

This group includes the hardware required to anchor the Sous-couche d'isolation de sol FAW J6P firmly to the cab floor. Given its exposed nature, this hardware must resist vibration and corrosion.

1. Composant: ‘Hex nut’ (CQ34006) – Quantité 25
Ce (Comp 4) is the primary structural nut. Twenty-five of these nuts are used to secure the various sections of the Sous-couche d'isolation de sol FAW J6P to the threaded studs or bolts welded into the cab floor. The large quantity emphasizes the need for extensive anchoring.

2. Composant: ‘Gasket – floor insulation pad’ (5109318-A01) – Quantité 25
Ce (Comp 5) is a specialized sealing and protective washer. Le Gasket Logic is two-fold: d'abord, it prevents the sharp edges of the steel nuts (Comp 4) from cutting into the soft insulation material (Comp 1, 2, 3), et deuxième, it provides a crucial seal against moisture where the bolt passes through the cab floor, preventing chassis corrosion. This is a critical serviceable component of the Sous-couche d'isolation de sol FAW J6P.

Le Logique de résistance aux vibrations in this assembly relies heavily on the constant clamping force provided by the nuts and the structural density of the pads themselves. Any loose hardware in the Sous-couche d'isolation de sol FAW J6P would quickly cause noise and fatigue in the cab floor.
