FAW Steering Wheel And Steering Transmission: لماذا هذه 17 Critical Components Define Driver Control

مرحبًا بك في هذا الدليل الفني المهم حول FAW Steering Wheel And Steering Transmission (حَشد 535). هذا هو الكامل, multi-part driver interface and linkage system for the FAW Jiefang CA4251P66K24T1A3E5 6×4 جرار نصف مقطورة ديزل. This assembly is the primary connection between the driver and the road.

ال FAW Steering Wheel And Steering Transmission هو “منطق” system with two main parts. The ‘Steering wheel & horn button assy’ (3402010-61ب) is the tactile interface. ال “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. سنقوم بتفكيك الكل FAW Steering Wheel And Steering Transmission التجمع فيه 17 مكونات صالحة للخدمة, including the main steering column, the protective shrouds, the floor seals, and all the critical fasteners that ensure a safe, precise steering feel.

المكون الأساسي: The ‘Steering Wheel’ (3402010-61ب)

ال FAW Steering Wheel And Steering Transmission assembly begins with the ‘Steering wheel & horn button assy’ (3402010-61ب). This is the primary tactile interface for the driver. It is far more than a simple “عجلة”; 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.

ال “الانتقال” منطق: عمود التوجيه (3403010A91W)

ال “Steering Transmission” جزء من FAW Steering Wheel And Steering Transmission is the ‘Steering column support & chain assy’ (3403010A91W). هذا هو الكامل “column” that the steering wheel mounts to. إنه “منطق” 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.
• **ال “Chain” (U-Joint):** ال “chain assy” part of the name refers to the universal joint (U-joint) at the base of the column. هذا “منطق” أمر بالغ الأهمية, 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’ (3403071-50أ) and its associated ‘Combination Bolt’ fasteners (CQ1421235, CQ1460625F6B). The quality of this component in the FAW Steering Wheel And Steering Transmission defines the “tightness” of the steering.

أمان & ختم: Shrouds and Dust Covers

A large part of the FAW Steering Wheel And Steering Transmission assembly is dedicated to safety, جماليات, and sealing the cab. The ‘Front steering column shroud’ (3403061-54دبليو) and ‘Rear steering column shroud’ (3403062-54دبليو) 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’ (3403067-50أ) and ‘Lower steering column shroud’ (3403051-50أ) are the critical sealing components. These are large, flexible rubber “boots” that are installed where the FAW Steering Wheel And Steering Transmission passes through the cab’s firewall/floor. هُم “منطق” is to create a 100% airtight and watertight seal. A torn boot here will allow a deafening amount of engine noise, حرارة, and toxic fumes to enter the driver’s cab, making the vehicle unusable. The ‘Buckle’ (3403063-10دبليو) is the clip that secures this boot.

The Fastener and Linkage “منطق”

ال 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 (ال “الانتقال” جزء) to the splined output of the column’s U-joint.

The ‘Combination Bolt’ (CQ1421235, CQ1460625F6B) and ‘Cross recessed pan head screw assembly’ (س2360616) are “حَشد” fasteners. هُم “منطق” 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’ (3403166-50أ) is a retaining clip. The ‘Yellow sheet nut’ (N015448) and ‘Gasket’ (Q40105) are used to secure the ‘Support’ (3403071-50أ) قوس, 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.
