Ensemble de couchette inférieure FAW: Une ventilation en 6 parties de votre système de confort essentiel

Welcome to this in-depth structural analysis of the Ensemble de couchette inférieure FAW (Assemblée 698). C'est le complet, 6-type de composant, structural foundation for the sleeper bunk in the FAW Jiefang CA4251P66K24T1A3E5 6×4 tracteur semi-remorque diesel. This assembly is not the mattress; c'est le “logique” system of welded frames, couvre, and storage boxes that *create* the “flat floor” living and resting space for the driver.

Le “logique” de la Ensemble de couchette inférieure FAW est double. D'abord, c'est le primaire “logique structurelle,” serving as the load-bearing frame that supports the driver and mattress, adding to the cab’s overall rigidity. Deuxième, c'est le “storage logic,” as this framework is engineered to create massive, intégré, and easily accessible storage compartments under the bunk, a critical feature for long-haul comfort.

Ce guide expert est essentiel pour les techniciens de cabine, spécialistes en réparation de collision, et gestionnaires de flotte. Nous déconstruirons l'ensemble Ensemble de couchette inférieure FAW dans son 6 types de composants réparables distincts. Nous analyserons le “double logique” of the main ‘Welded Support Frames’ (Composants 1 & 2), le “porteur” logic of the ‘Cover Plate’ (Composant 4), le “commodité” logic of the ‘Storage Box’ (Composant 5), et la critique “anti-vibration” système de fixation.

Cœur 1: Le “Cadre structurel” Logique (Composants 1 & 2) (Le “Plus long” Module)

La fondation du Ensemble de couchette inférieure FAW est-ce que c'est “squelette.” This is comprised of the ‘Left sleeper support frame welded assy’ (7007010-A09, etc.) and the ‘Right sleeper support frame welded assy’ (7007040-A09, etc.). These are the primary structural components.

1. Le “Load-Bearing” Logique:

C'est le “châssis” of the bunk. Ce “logique” is to provide an unyielding, rigid foundation. This welded steel frame must support the static weight of the mattress and one or two resting drivers (150kg+), *plus* the dynamic G-forces of the cab bouncing on the highway.

This frame is fabricated from high-strength, precision-welded steel. C'est le “logique” component that provides the torsional rigidity (résistance à la torsion) for the entire sleeper compartment. It is securely fastened (using MSU 3) to the ‘Welded Cab Assembly’ (Assemblée 617) rear bulkhead and floor.

2. Le “Integrated Storage” Logique:

Le “logique” of this frame is not just support; it is *space creation*. The welded frame is not a solid block; it is an open “truss” structure. This design “logique” is what *creates* the large, ouvrir, and secure storage bays under the bunk. This is the most valuable space in a long-haul cab, and this Ensemble de couchette inférieure FAW is engineered to maximize it.

3. Le “Variant & Service” Logique:

The parts list shows *five different part numbers* for the Left/Right frames (A09, AB27, CB27, etc.). Ce “variant logic” is critical for parts managers. These different frames are designed for different cab configurations. Par exemple, a cab *with* an “independent heater” (like Assembly 692) or a factory-installed refrigerator will require a frame with *different mounting points* and cutouts.

As serviceable parts, these welded frames are the primary components replaced after a severe collision (especially a rear-end or side-impact) that has compromised the cab’s structural integrity. A bent frame will cause the storage lids (Composant 4) to bind and the bunk to be un-level.

Cœur 2: Le “Modular Storage” Logique (Composants 4 & 5)

This group of components provides the “orienté vers l'utilisateur” une partie du Ensemble de couchette inférieure FAW système de stockage.

Composant 4: ‘Right upper cover plate assy’ (7007130-A01): C'est le “logique” de “access.” C'est le grand, plat, de construction “couvercle” that covers the storage bay created by the ‘Right support frame’ (Composant 2).

Ce composant “logique” est double: 1) C'est un “couvercle” that is hinged to provide access to the storage below. 2) It is also the “sol” of the bunk. It is a load-bearing panel, reinforced with stamped ribs on its underside, to be strong enough to support the mattress and driver without “affaissement” ou “flexing.”

Composant 5: ‘Storage box assy I-sleeper’ (7007110-A01): C'est le “commodité” logique. While Component 4 est un “couvercle,” this is a complete, pre-molded “tub” ou “box.” Ce “logique” est de fournir un “faire le ménage” storage area, often for the ‘On-board Tools’ (Assemblée 598).

This polymer box is a “drop-in” serviceable part. C'est “logique” is to isolate its contents (tools, sangles) de la “carpeted” main area, making it durable and easy to clean. This modularity is a key part of the Ensemble de couchette inférieure FAW.

Cœur 3: Le “Anti-hochet” Logique de fixation (Composants 3 & 6)

Ce dernier groupe est le “Logique NVH” qui tient le Ensemble de couchette inférieure FAW together and ensures a silent ride. UN “cliquetis” sleeper bunk is a non-starter for driver comfort.

Composant 3: «Écrou hexagonal’ (CQ34006) – Quantité 14: C'est le “de construction” logique de fixation. Ces 14 nuts are what secure the ‘Left’ and ‘Right Support Frames’ (Composants 1 & 2) to the ‘Welded Cab Assembly’ (617) floor/wall.

Ce sont des produits à haute résistance, “couple dominant” (Nyloc) contre-écrous. Leur “logique” doit être *immunisé contre les vibrations*. A standard nut *would* vibrate loose. This self-locking design is a critical, single-use safety component.

Composant 6: '…Vis combinée’ (Q2360620F6) – Quantité 8: C'est le “anti-hochet” logic for the *storage*. Ces 8 screws are what fasten the ‘Storage box’ (Composant 5) and the hinges for the ‘Cover plate’ (Composant 4) *to* the welded frame.

UN “Combinaison” (combinaison) screw has a captive, pre-attached *lock washer*. Ce “logique” fournit une tension constante, preventing the plastic box and lids from “bourdonnant” ou “cliquetis” against the metal frame. Cela garantit la Ensemble de couchette inférieure FAW is absolutely silent.
