FAW Steering Wheel And Steering Transmission: Почему эти 17 Critical Components Define Driver Control

Добро пожаловать в это важное техническое руководство по FAW Steering Wheel And Steering Transmission (Сборка 535). Это полный, multi-part driver interface and linkage system for the FAW Jiefang CA4251P66K24T1A3E5 6×4 дизельный полуприцеп тягач. This assembly is the primary connection between the driver and the road.

The FAW Steering Wheel And Steering Transmission является а “логика” system with two main parts. The ‘Steering wheel & horn button assy’ (3402010-61Б) is the tactile interface. The “Steering Transmission” is the ‘Steering column support & chain assy’ (3403010A91W) and its associated linkages, which transmit the driver’s rotational input from the cab, down through the floor, to the main steering gearbox.

This in-depth guide is an essential resource for professional chassis technicians and parts specialists. Мы разберем всю FAW Steering Wheel And Steering Transmission сборка в свой 17 исправные компоненты, including the main steering column, the protective shrouds, the floor seals, and all the critical fasteners that ensure a safe, precise steering feel.

Основной компонент: The ‘Steering Wheel’ (3402010-61Б)

The FAW Steering Wheel And Steering Transmission assembly begins with the ‘Steering wheel & horn button assy’ (3402010-61Б). This is the primary tactile interface for the driver. It is far more than a simple “колесо”; it is an ergonomically designed and safety-engineered component.

This component is typically constructed from a high-grip, durable polyurethane material molded over a strong, steel or magnesium-alloy frame. The diameter and rim thickness are precisely engineered to provide the correct amount of leverage for controlling a heavy-duty truck (even with power steering failure), while also giving the driver a clear view of the instrument cluster.

The integrated ‘horn button assy’ is the main safety-warning device. A failure here is not just an inconvenience, it is a critical safety failure. The ‘Steering wheel’ mounts to the ‘Steering column support & chain assy’ (3403010A91W) via a splined shaft and a single, high-torque locking nut. The precision of this entire FAW Steering Wheel And Steering Transmission is what gives the driver a feeling of confidence and control.

The “Передача инфекции” Логика: Рулевая колонка (3403010A91W)

The “Steering Transmission” часть FAW Steering Wheel And Steering Transmission is the ‘Steering column support & chain assy’ (3403010A91W). Это полный “column” that the steering wheel mounts to. Его “логика” is to transfer the driver’s rotational input from inside the cab, down through the cab floor, to the intermediate steering shaft.

This is a complex assembly that includes:

• **A Collapsible Core:** For safety, this column is designed to collapse upon itself in a frontal collision, preventing it from being forced into the driver’s chest.
• **Tilt/Telescope Mechanism:** It contains the locking mechanism (often a lever) that allows the driver to adjust the wheel’s height and distance for comfort.
• **The “Chain” (U-Joint):** The “chain assy” part of the name refers to the universal joint (U-joint) at the base of the column. Этот “логика” имеет решающее значение, as it allows the column to connect to the intermediate shaft at an angle, while still transmitting 100% of the rotational force.

This entire column is mounted to the truck’s dashboard substructure via the ‘Support’ (3403071-50А) and its associated ‘Combination Bolt’ крепежные детали (CQ1421235, CQ1460625F6B). The quality of this component in the FAW Steering Wheel And Steering Transmission defines the “tightness” of the steering.

Безопасность & Уплотнение: Shrouds and Dust Covers

A large part of the FAW Steering Wheel And Steering Transmission assembly is dedicated to safety, эстетика, and sealing the cab. The ‘Front steering column shroud’ (3403061-54Вт) and ‘Rear steering column shroud’ (3403062-54Вт) are the two “clamshell” plastic covers that wrap around the steering column.

These shrouds serve two functions. Aesthetically, they hide the column, the ignition switch, and the wiring for the turn signals. For safety, they prevent the driver’s clothing or other items from becoming entangled in the spinning steering shaft. They are secured with fasteners like the ‘Cross recessed countersunk head self-tapping screw’ (CQ2714245).

The ‘Steering column dust cover’ (3403067-50А) and ‘Lower steering column shroud’ (3403051-50А) are the critical sealing components. These are large, flexible rubber “сапоги” that are installed where the FAW Steering Wheel And Steering Transmission passes through the cab’s firewall/floor. Их “логика” is to create a 100% airtight and watertight seal. A torn boot here will allow a deafening amount of engine noise, нагревать, and toxic fumes to enter the driver’s cab, making the vehicle unusable. The ‘Buckle’ (3403063-10Вт) is the clip that secures this boot.

The Fastener and Linkage “Логика”

The FAW Steering Wheel And Steering Transmission is held together by a variety of specialized, vibration-resistant fasteners. The ‘Rod-driven flexible shaft B-type clamp’ (CQ676100B) is a high-torque clamp used to secure the flexible steering shaft (а “transmission” часть) to the splined output of the column’s U-joint.

The ‘Combination Bolt’ (CQ1421235, CQ1460625F6B) and ‘Cross recessed pan head screw assembly’ (Q2360616) являются “сборка” крепежные детали. Их “логика” is that they have pre-installed, captive lock washers. This is a critical manufacturing and service feature that prevents a technician from forgetting the lock washer, which would allow a critical component of the FAW Steering Wheel And Steering Transmission to vibrate loose. *

The ‘Card-front steering column shroud’ (3403166-50А) is a retaining clip. The ‘Yellow sheet nut’ (N015448) and ‘Gasket’ (Q40105) are used to secure the ‘Support’ (3403071-50А) кронштейн, providing a wide clamping surface. Every piece of hardware in the FAW Steering Wheel And Steering Transmission is designed for high-vibration, safety-critical applications.
