Ligne de direction assistée FAW J6P: Déconstruction 21 Pièces critiques pour une assistance hydraulique parfaite

This is a complete technical guide to the Ligne de direction assistée FAW J6P system for the FAW Jiefang CA3250P66K2L1T1E 6×4 tombereau. Cette déconstruction analyse 21 serviceable component groups that form the complete hydraulic circuit, from the fluid reservoir and pump to the high-pressure hoses and steering gear.

Le Ligne de direction assistée FAW J6P system is the complete hydraulic network that provides steering assist to the driver. Dans un camion-benne lourd, this system is non-negotiable for safe maneuvering, especially at low speeds with a full load. It works by using a pump (driven by the engine) to pressurize hydraulic fluid, which is then directed by the steering gear to assist in turning the front wheels. This deconstruction will analyze the four key parts of the Ligne de direction assistée FAW J6P circuit: the fluid reservoir (storage), the pump (pressurization), the high-pressure lines (delivery), and the steering gear (actionnement). A leak-free, properly functioning Ligne de direction assistée FAW J6P is critical for vehicle control and reducing driver fatigue.

Cœur 1: Le “Réservoir” Logique (Fluid Storage & Filtering)

This group of components forms the start and end of the hydraulic circuit. It is responsible for storing, filtering, and de-aerating the power steering fluid. This is a critical part of the Ligne de direction assistée FAW J6P.

1. Composant: ‘Power steering reservoir assy (Style drawing)’ (3408010-716) – Quantité 1
Ce (Comp 1) is the complete reservoir assembly. It is composed of a ‘Welded reservoir assy’ (3408020-716) and an ‘Upper cover’ (3408037-716). Its function is to hold the reserve of hydraulic fluid needed by the Ligne de direction assistée FAW J6P.

2. Composant: ‘Filter element with joint assy’ (3408015-716) – Quantité 1
This is a critical serviceable component located inside the reservoir. Le Filtering Logic is that all return fluid passes through this filter before it can re-enter the pump. This removes metal particles and debris, protecting the pump (Comp 11) and steering gear (Comp 17) from abrasive damage. A clogged filter in the Ligne de direction assistée FAW J6P will cause the pump to cavitate and fail.

3. Composant: ‘Breather cap’ (3408027-716) & ‘Sealing rings’ (3408051-716, 3408052-716)
Ce (Comp 1 sub-parts) is the cap system. The ‘Breather cap’ allows air to enter and escape as the fluid level changes with temperature, while the ‘Sealing rings’ ensure a leak-proof seal on the cover. This system is essential for the health of the Ligne de direction assistée FAW J6P.

Cœur 2: Le “Actuator” Logique (The Steering Gear)

C'est le “muscle” de la Ligne de direction assistée FAW J6P système. It is a hydraulic-mechanical gearbox that uses fluid pressure to multiply the driver’s steering input.

1. Composant: ‘Power steering gear assy (Shashi steering gear)’ (3411010-14B-C00) – Quantité 1
Ce (Comp 17) is the main steering gear. Le Hydraulic Assist Logic est interne: as the driver turns the wheel, a valve inside this unit directs high-pressure fluid from the ‘High pressure hose assy’ (Comp 21) to one side of a piston, providing the powerful assist needed to turn the heavy front wheels.

2. Composant: ‘Steering gear bracket’ (3403016-14B) – Quantité 1
Ce (Comp 18) is the heavy-duty cast bracket used to rigidly mount the steering gear (Comp 17) au Cadre FAWJ6P. It is secured with high-tensile hardware (Comp 19, 20) to withstand the immense twisting forces of the steering.

Cœur 3: Le “Pression & Return” Logique (The Hoses)

This group of components forms the ‘plumbing’ de la Ligne de direction assistée FAW J6P. It includes the specialized hoses designed to handle the high-pressure and low-pressure fluid.

1. Composant: ‘High pressure hose assy’ (3406030-14B) – Quantité 1
Ce (Comp 21) is the most critical hose in the Ligne de direction assistée FAW J6P. It is a multi-layer, wire-reinforced hose designed to withstand extremely high hydraulic pressure (often 1500-2000 psi) from the pump. It uses ‘Banjo bolts’ (3406021-91) and ‘Combined seal washers’ (3406321A8E) for a high-pressure, leak-proof connection. A failure here results in an immediate loss of all steering assist.

2. Composant: ‘Inlet hose’ (3406011-14B) – Quantité 1
Ce (Comp 5) is the low-pressure “suction” hose. It connects the ‘Reservoir’ (Comp 1) to the inlet of the ‘Power steering pump’ (Comp 11). It is a larger-diameter hose designed to feed the pump with an unrestricted flow of fluid.

3. Composant: ‘Return hose assy’ (3406040-14B) – Quantité 1
Ce (Comp 6) is the low-pressure return line. It carries the “used” hydraulic fluid from the ‘Steering gear’ (Comp 17) back to the ‘Reservoir’ (Comp 1) to be filtered and cooled. This completes the circuit of the Ligne de direction assistée FAW J6P.

Cœur 4: Le “Pump & Montage” Logique (The Power Source)

This is the power source for the entire Ligne de direction assistée FAW J6P système. It is a belt-driven pump that converts engine rotation into hydraulic pressure.

1. Composant: ‘Power steering pump assy’ (3407020-61B-C00) – Quantité 1
Ce (Comp 11) is the hydraulic pump itself. It is the heart of the Ligne de direction assistée FAW J6P. It draws low-pressure fluid from the ‘Inlet hose’ (Comp 5) and pressurizes it, sending it out through the ‘High pressure hose’ (Comp 21).

2. Composant: ‘Support bracket assy’ (3406115-70U) & ‘Support’ (3406111-70U)
Ce (Comp 13) is the set of heavy-duty brackets used to mount the power steering pump (Comp 11) securely to the engine. This rigid mounting is essential to maintain proper belt alignment and resist vibration.

3. Composant: ‘Hose Clamps’ & ‘Straps’ (CQ67627B, CQ676120B, T67414616, 3406027-76UN)
Ce (Comp 5, 17, 8, 12) est le Vibration Protection Logic. The ‘Worm drive hose clamps’ secure the low-pressure lines. The ‘Double pipe clamp’ (Comp 12) and ‘Plastic strap’ (Comp 8) are used to secure the hoses to the chassis, preventing the Ligne de direction assistée FAW J6P from chafing on the frame and failing.
