Conjunto do assento do motorista FAW: O segredo em 6 partes para o conforto ao dirigir o dia todo

Welcome to this critical ergonomic and safety analysis of the Conjunto do assento do motorista FAW (Conjunto 695). Este é o completo, 6-tipo de componente, “Air-Ride” (suspensão a ar) e “Heated” (electric heat) driver’s seat for the FAW Jiefang CA4251P66K24T1A3E5 6×4 trator semirreboque diesel. This is arguably the single most important “lógica” assembly for driver health, segurança, and long-haul comfort.

O Conjunto do assento do motorista FAW (P/N 6800010BD04-C00) é um sofisticado, “lógica dupla” sistema. Its first “lógica” é “Air Suspension,” using a dedicated ‘Air horn assy’ (3506805-91C) and ‘Air tube assy’ (6800020AA01) para “float” the driver, isolating them from the truck’s chassis vibration. É o segundo “lógica” é “Electric Heat,” (as noted in the title), providing critical comfort and reducing muscle fatigue in cold-weather operation.

This in-depth guide is essential for fleet managers and technicians. Vamos desconstruir todo Conjunto do assento do motorista FAW em seu 6 distinct Minimum Serviceable Unit (Universidade Estadual de Moscou) types. Iremos analisar o “estrutural” logic of the main ‘Seat Assy’ (Universidade Estadual de Moscou 1), o “pneumatic” (air-ride) logic of the ‘Air Tube’ and ‘Air Horn’ (Universidades Estadunidenses 2 & 3), e o crítico “antivibração” lógica de fixação (Universidades Estadunidenses 4, 5, 6) that secures the driver to the cab.

Universidade Estadual de Moscou 1: O “Dual-Logic” Essencial – ‘Driver Seat Assy’ (6800010BD04-C00) (O “Mais longo” Módulo)

The ‘Driver seat assy’ is the primary component and MSU 1. Este é o “black box” do Conjunto do assento do motorista FAW. É um “lógica” assembly that is replaced as a single unit. It combines a structural frame, ergonomic foam, a durable cover, and its two “active” logic systems: Air Suspension and Electric Heat.

1. O “Air-Ride” Suspension Logic:

This is the core “health and safety” lógica. A truck’s chassis is subjected to constant, high-frequency “road buzz” and low-frequency “bouncing.” Esse “lógica” of the ‘Air-Ride’ seat is to *isolate* the driver’s spine from this vibration.

O Conjunto do assento do motorista FAW contains an integrated “air spring” (a rubber airbag) and a height-adjustment valve. This valve (fed by MSU 2 & 3) allows the driver to add or remove air, “tuning” the seat to their exact weight. Esse “floats” the driver, absorbing up to 90% of the harmful vibrations that lead to chronic back pain and driver fatigue.

2. O “Electric Heat” Lógica:

As the title notes, this is an “electric heated” seat. Esse “lógica” is for both comfort and health. Buried beneath the seat’s upholstery are “resistive heating elements” (wires).

In cold-weather operation, the driver can activate this system, which provides “lógica”-controlled, therapeutic warmth to the seat cushion and lumbar (lower back) area. Esse “lógica” is critical for preventing muscle stiffness and back strain during long, cold hauls.

3. O “Ergonomic & Safety” Lógica:

O Conjunto do assento do motorista FAW é o “HMI” for the driver’s body. Isso é “lógica” é “adjustability.” The seat features multiple controls for:

• Lumbar Support: An adjustable (often pneumatic) cushion that presses into the driver’s lower back to maintain a healthy posture.
• Fore/Aft & Rake: Slides and backrest angle, allowing the driver to achieve the perfect, safe distance from the steering wheel and pedals.
• Side Bolsters: “Wings” on the cushion and backrest that “lógica” is to hold the driver securely in place during sharp turns.

Facilidade de manutenção (Universidade Estadual de Moscou): The ‘Driver seat assy’ is the primary MSU. It is a sealed unit. If the air-ride valve fails, the heater element burns out, or the internal frame cracks, the *entire* assembly (6800010BD04-C00) is unbolted (via MSUs 4, 5, 6) and replaced.

Essencial 2: O “Pneumatic Supply” Lógica (Universidades Estadunidenses 2 & 3)

This group of MSUs is the “lifeblood” of the air-ride system. Este é o “lógica” that feeds the Conjunto do assento do motorista FAW with high-pressure air from the truck’s main pneumatic system.

Universidade Estadual de Moscou 2: ‘Air tube-multiway joint to air horn’ (3506805-91C)

Universidade Estadual de Moscou 3: ‘Air outlet tube-driver seat’ (6800020AA01)

These two MSUs form the complete “encanamento” from the chassis to the seat. O “lógica” is as follows:

• “Supply Logic” (Universidade Estadual de Moscou 2): This tube “taps” into the truck’s main air system (at a “multiway joint”) and delivers that air to the ‘Air Horn’. O “Air Horn” (气喇叭) in this context is a “lógica” mistranslation; it is the *valve* or *regulator* for the seat.
• “Delivery Logic” (Universidade Estadual de Moscou 3): This is the final “pigtail” that connects the regulator *to* the air-intake port on the ‘Driver Seat Assy’ (Universidade Estadual de Moscou 1).

These are critical MSUs. The tubing is made from high-pressure, oil-resistant nylon. O #1 falha “lógica” is chafing. If not routed correctly, these tubes can “chafe” against the cab’s metal floor, creating a pinhole leak. Isto resulta em um “hissing” som, a “morto” seat that won’t inflate, and a dangerous air-loss from the main brake system.

Essencial 3: O “Antivibração” Lógica do Fixador (Universidades Estadunidenses 4, 5, 6)

This final group of MSUs is the “lógica” that secures the Conjunto do assento do motorista FAW to the cab floor. This is a safety-critical, 18-piece (6+6+6) sistema.

Universidade Estadual de Moscou 5 & 6: ‘Air tube clamp-driver seat’ (6800016AA01) & 'Porca hexagonal’ (CQ34005) – Quantidade 6 (cada)

Este é o “anti-chafe” lógica. The six ‘Clamps’ are used to securely fasten the ‘Air Tube’ (Universidade Estadual de Moscou 3) to the seat’s sub-frame and the cab floor. The six ‘Nuts’ secure these clamps. Esse “lógica” is critical to prevent the chafing and air leaks described above.

Universidade Estadual de Moscou 4: ‘Combination bolt’ (CQ1460825F6) – Quantidade 6

Este é o “structural logic.” These six (6) heavy-duty bolts are what secure the ‘Driver Seat Assy’ (Universidade Estadual de Moscou 1) *to the cab floor*.

O “Combinação” (combinação) logic is the key. Estes não são parafusos padrão. They are MSUs with a *captive, pre-attached lock washer* (Por exemplo, a serrated or spring washer).

A driver’s seat is under constant vibration and shear-force (from acceleration/braking). A standard bolt *would* vibrate loose. O “lock washer” on this bolt “bites” into the seat’s metal frame, providing constant tension. Esse “antivibração” logic is a critical safety feature that ensures the driver’s seat *cannot* detach from the cab floor in a collision.
