FAW الحرس الخلفي الروسي: جارٍ النشر 45 المكونات الهيكلية للسلامة التامة من الصدمات الخلفية

ال FAW الحرس الخلفي الروسي logic assembly serves as the final defensive perimeter for the CA3250P66K24L1TE5Z heavy-duty dump truck. Engineered to meet stringent Rear Underrun Protection Device (RUPD) المعايير, this system is designed to prevent smaller passenger vehicles from sliding beneath the chassis during collisions. Constructed from specialized low-temperature alloy steel, ال FAW الحرس الخلفي الروسي maintains its structural ductility even in the brittle -50°C environment of the Siberian winter. This guide analyzes the energy-absorbing brackets, the rigid cross-beam architecture, and the high-tensile fastening systems that ensure safety and compliance.

FAW الحرس الخلفي الروسي

Bracket Architecture and Energy Absorption

السلامة الهيكلية لل FAW الحرس الخلفي الروسي relies heavily on its mounting system, specifically the Rear Protection Left Bracket (الجزء لا. 2809211-54ق) and the Rear Protection Right Bracket (الجزء لا. 2809212-54ق). These components act as the interface between the rigid chassis frame and the impact beam. في “Russian Spec” إعدادات, these brackets are manufactured from “54ق” grade steel. This metallurgy is chosen specifically for its high yield strength and improved impact toughness at sub-zero temperatures. Standard structural steel can become brittle when frozen, snapping under load; لكن, ال FAW الحرس الخلفي الروسي brackets are designed to deform plastically, absorbing kinetic energy and reducing the deceleration forces transferred to the truck chassis.

The geometry of these brackets is engineered to position the cross beam at the precise height required by international safety regulations (typically 550mm from the ground). This positioning is critical for engaging the crumple zones of impacting passenger cars. The connection to the chassis frame is secured using the Hexagon Head Flange Bolt (الجزء لا. Q1841455T). Eight of these heavy-duty bolts are utilized to clamp the brackets to the frame rails. The flange head design distributes the clamping load over a wide area, preventing the bolt head from embedding into the bracket steel, which ensures that the torque tension remains consistent even after years of thermal cycling.

بالإضافة إلى, ال FAW الحرس الخلفي الروسي system employs the Hexagon Flange Lock Nut (الجزء لا. CQ32614) for these connections. These nuts feature a prevailing torque feature that prevents loosening due to the severe vibration inherent in off-road dump trucking. في سياق FAW الحرس الخلفي الروسي, a loose bracket would not only fail safety inspections but could lead to the guard detaching during operation. The robust fastening logic ensures that the brackets remain an immovable foundation for the entire protective system.

The Impact Beam: الصلابة الهيكلية

Spanning the width of the vehicle is the Rear Protection Cross Beam Assembly (الجزء لا. 2809220-54ق). هذا هو العضو المؤثر الأساسي في FAW الحرس الخلفي الروسي. Fabricated from a closed-section steel profile, this beam offers exceptional resistance to bending and torsional forces. ال “54ق” material specification ensures that the beam retains sufficient ductility to bend without cracking when subjected to a high-speed rear impact. This controlled deformation is a key safety feature, منع FAW الحرس الخلفي الروسي from acting as a rigid wall that could cause fatal deceleration forces for the occupants of the impacting vehicle.

The mounting of the cross beam to the vertical brackets utilizes a specific fastening strategy involving 12 units of the Hexagon Flange Bolt (الجزء لا. Q1841440T). These bolts feature a “عرقوب خشنة” (نوع قياسي) تصميم. The coarse thread profile provides superior resistance to stripping and fatigue compared to fine threads, especially in soft or ductile materials. في FAW الحرس الخلفي الروسي حَشد, this robustness is vital because the beam is often subjected to vertical loads when the truck bottoms out in deep ruts or when the guard is inadvertently used as a push-bar by bulldozers in the pit.

The ends of the cross beam are sealed with the Rear Protection Cross Beam End Cover (الجزء لا. 2809213-60ن). While seemingly minor, these covers play a crucial role in the longevity of the FAW الحرس الخلفي الروسي. They prevent road salt, الطين, and acidic slurry from entering the hollow beam. بدون هذه الأغطية, the beam would corrode from the inside out, silently compromising its structural integrity. ال “60ن” material indicates a polymer or composite that remains flexible in the cold, maintaining a tight seal against the steel beam even when temperatures drop to -50°C.

Fastening Logic and Corrosion Resistance

موثوقية FAW الحرس الخلفي الروسي is ultimately defined by the quality of its fasteners. The assembly uses a total of 20 high-tensile flange nuts (الجزء لا. CQ32614) to secure both the brackets and the cross beam. The flange design eliminates the need for separate flat washers, reducing the parts count and minimizing the risk of assembly errors. This integrated washer face also provides a larger surface area to span over the mounting holes, which is particularly important for the slotted holes often used in the FAW الحرس الخلفي الروسي brackets to allow for alignment adjustments.

Corrosion is the arch-enemy of chassis components in Russia, where magnesium chloride and other aggressive de-icers are used liberally. The bolts and nuts used in the FAW الحرس الخلفي الروسي undergo a specialized zinc-flake or Dacromet coating process. This sacrificial coating protects the steel fastener from rust even if the surface is scratched during installation. بالإضافة إلى, the main steel components—the brackets and the beam—are treated with a heavy-duty chassis paint that bonds molecularly with the steel, preventing the underfilm corrosion that plagues inferior aftermarket parts.

Maintenance teams must pay close attention to the torque settings of these fasteners. Due to the settling of paint layers and the relaxation of the bolted joints, ال FAW الحرس الخلفي الروسي bolts should be re-torqued after the first 5,000 km of service. Neglecting this step can lead to “bolt walk,” where the fasteners vibrate loose, leading to a rattling guard and eventual structural failure. تصميم FAW الحرس الخلفي الروسي facilitates easy access to all bolt heads, encouraging regular inspection and maintenance.

خاتمة: A Vital Safety Asset

ال FAW الحرس الخلفي الروسي is more than a simple bumper; it is a legally mandated safety system that protects other road users and the rear structure of the truck itself. من خلال الجمع “54ق” low-temperature steel with a robust, vibration-resistant fastening architecture, FAW has created a component that delivers consistent performance in the most demanding operational theaters. لمديري الأسطول, سلامة FAW الحرس الخلفي الروسي is a direct reflection of their commitment to safety and compliance.

Regular inspection of the cross beam for deformation and checking the torque on the mounting bolts are simple yet effective ways to ensure the longevity of this system. Using only genuine FAW replacement parts for the FAW الحرس الخلفي الروسي guarantees that the steel metallurgy matches the original design specifications, maintaining the crucial balance between rigidity and energy absorption that keeps the roads safe for everyone.
