FAW Русский задний правый тормоз в сборе: Деконструкция 50 Стратегические компоненты для сбалансированной деятельности в Арктике

The FAW Русский задний правый тормоз assembly is the complementary force in the CA3250P66K24L1TE5Z dump truck’s rear deceleration system. As the final node in the pneumatic circuit, this brake unit demands precise timing and force application to prevent yaw instability during emergency stops on icy Russian roads. Built with cold-resistant metallurgy and reinforced friction linings, а FAW Русский задний правый тормоз operates seamlessly in temperatures as low as -50°C. This guide provides a detailed breakdown of the S-cam geometry, automatic adjustment mechanisms, and critical mounting hardware that constitute the FAW Русский задний правый тормоз.

FAW Русский задний правый тормоз

Robust Friction Architecture for Severe Loads

The FAW Русский задний правый тормоз distinguishes itself with a significantly robust friction coupling designed for the tandem drive axles. The assembly utilizes 410mm diameter drums coupled with the massive Задняя тормозная колодка (Часть №. 3502391-А6Е). Unlike the front axle, the rear shoes carry a much larger surface area of friction material, split into Задняя фрикционная накладка I (Часть №. 3502406-А6Е) и Задняя фрикционная накладка II (Часть №. 3502407-А6Е). This segmented design prevents thermal stress cracking by allowing for differential expansion across the lining surface during prolonged braking events in the Russian tundra.

Structural rigidity is paramount. The Задний тормозной кронштейн (Часть №. 3502021-А0Е) serves as the anchor point, bolted directly to the axle housing with high-tensile Блокирующий болт – For Fastening Rear Brake Bracket (Часть №. 3502038-1ЧАС). This bracket must withstand torque loads exceeding 25,000 Nm without deflection. The Ось задней тормозной колодки / Анкерный штифт (Часть №. 3502086-А6Е) provides the pivot point for the shoes. In this heavy-duty specification, these pins are hardened to resist ovalization, ensuring that the brake geometry remains precise over hundreds of thousands of kilometers.

Retention of the friction components is managed by the ВЕРНАЯ ВЕСНА (Часть №. 3502436-А0Е). These springs are critical for dragging the heavy shoes away from the drum immediately after the pedal is released. В FAW Русский задний правый тормоз, these springs are cadmium-plated to resist corrosion from road salts used on icy Russian highways. Failure of these springs leads to brake drag, overheating, and potentially wheel-end fires, making their inspection a priority during maintenance.

Camshaft Actuation and Adjustment Logic

The actuation force in the FAW Русский задний правый тормоз is delivered through the Задний правый тормозной распредвал (Часть №. 3502152-А6Е). This component features a reverse-helix S-profile, specifically machined to actuate the right-side shoes against the drum’s rotation. It is supported by a sophisticated bearing system involving the Шарнирный подшипник распределительного вала в сборе (Часть №. 3502135-А0Е). This spherical bearing design accommodates slight axle flex under heavy loads without binding the camshaft, a common failure mode in rigid bearing designs.

Driving the camshaft is the Rear Axle Right Automatic Adjuster Arm Assy (Часть №. 3502210-А0Е). This Haldex-style adjuster senses the clearance between the lining and the drum on every stroke. If the gap exceeds the factory specification due to wear, the internal worm gear ratchets forward, maintaining optimal braking efficiency. This automatic adjustment is crucial for the FAW Русский задний правый тормоз, as manual adjustment of 8 rear wheel positions in -40°C weather is both impractical and dangerous.

The interface between the S-cam and the shoes is smoothed by the Задняя тормозная колодка с роликовым узлом (Часть №. 3502375-А6Е). Эта сборка включает в себя Ролик тормозной колодки (Часть №. 3502392-А0Е) и Роликовый вал (Часть №. 3502394-А0Е). These rollers reduce mechanical hysteresis, ensuring that the brakes apply and release linearly with pedal pressure. The Роликовая втулка (Часть №. 3502393-А0Е) is internally lubricated, preventing the roller from seizing and flat-spotting, which would cause a pulsating brake pedal.

Sealing and Environmental Defense

Operating in the muddy, gritty environment of a mine site requires exceptional sealing. The FAW Русский задний правый тормоз features a multi-barrier defense system. The primary barrier is the Задний тормоз Задний пылезащитный щиток (Часть №. 3502031-А0Е) и Передний пылезащитный щиток заднего тормоза (Часть №. 3502032-А0Е). These stamped steel shields interlock to encase the drum, preventing rocks from entering and damaging the friction surfaces. Смотровые отверстия закрыты герметиком. Затыкать – Смотровое отверстие пылезащитного экрана (Часть №. 3501034-02), allowing for quick visual checks without disassembly.

Internal contamination is prevented by the Сальник – Кронштейн распределительного вала (Часть №. 3502153-А0Е). This double-lipped seal keeps the chassis grease inside the camshaft bracket and prevents water ingress. A failure here would allow water to wash away the lubricant, leading to camshaft corrosion and seizure. The assembly also uses the Сиденье – Сальник (Часть №. 3502124-А0Е) to position the seal correctly, ensuring consistent lip pressure on the shaft regardless of thermal expansion.

Even the smaller components are designed for retention. The Запорная пластина – Болт крепления оси тормозной колодки (Часть №. 3501087-4Э) acts as a mechanical fuse, preventing the anchor pins from backing out under vibration. The use of multiple Стопорное кольцо вала (Часть №. Q43112) units ensures that the roller shafts and pivot pins remain captive. This attention to detail prevents catastrophic disassembly of the FAW Русский задний правый тормоз during operation.

Maintenance and Power Application

The brute force required to actuate the rear brakes is provided by the Rear Axle Right Spring Cylinder with Quick Connector Assy (Часть №. 3530030-896-С00). This dual-chamber actuator provides both service braking via air pressure and parking/emergency braking via a powerful internal spring. It is mounted to the Support Plate – Spring Brake Cylinder (Часть №. 3502126A483). This heavy-gauge plate prevents the cylinder from flexing under load, ensuring that 100% of the pushrod force is directed into the slack adjuster.

Maintenance access is facilitated by the Прямая масленка (Часть №. CQ70001). Located on the camshaft brackets and the slack adjuster, these fittings allow mechanics to purge old, contaminated grease and replace it with fresh low-temperature lubricant. The Регулировочная шайба тормоза (Часть №. 3501156A392) allows for fine-tuning of the camshaft end-play. Excessive end-play causes the S-cam to walk laterally, leading to uneven lining wear. Correct shimming is a critical step in rebuilding the FAW Русский задний правый тормоз.

Окончательно, the integration of ABS is supported by the Rear Wheel Speed Sensor Bracket (Часть №. 3605366-93Вт). This bracket positions the sensor within millimeters of the tone ring. A stable bracket is essential for preventing sensor drop-out signals which would trigger ABS fault codes. Поддерживая FAW Русский задний правый тормоз with genuine components like the Заклепка – Тормозная накладка (Часть №. 3502408-А0Е), operators ensure that the vehicle remains compliant with safety regulations and capable of stopping safely in any condition.

Заключение: The Backbone of Heavy Haulage

The FAW Русский задний правый тормоз is a masterpiece of heavy-duty engineering, comprised of 50 strategic components working in concert. From the massive clamping force of the Rear Axle Right Spring Cylinder to the precise modulation of the Задний правый тормозной распредвал, every element is designed for durability and safety. The robust sealing and automatic adjustment features minimize downtime and maximize operational efficiency in the harshest environments on earth.

Для владельцев автопарков, the path to reliability lies in using genuine parts. Substituting critical items like the Задняя тормозная колодка или ВЕРНАЯ ВЕСНА with inferior aftermarket alternatives compromises the safety of the entire vehicle. By adhering to the specifications outlined in this breakdown of the FAW Русский задний правый тормоз, operators invest in the long-term performance and safety of their fleet.
