Welcome to this critical technical guide to the Схема сборки карданного вала FAW. Эта сборка, также известный как “propeller shaft” или “propshaft,” is the complete system for transmitting power from the transmission to the drive axles on the FAW Jiefang CA4251P66K24T1A3E5 6×4 дизельный полуприцеп тягач.
The Схема сборки карданного вала FAW illustrates a system of two main shafts: a main driveshaft from the gearbox to the first rear axle, and an inter-axle driveshaft connecting the two rear axles. This system must handle 100% of the engine’s multiplied torque while constantly flexing with the truck’s suspension.
Это подробное руководство является важным ресурсом для профессиональных технических специалистов и менеджеров автопарков.. Мы разберем всю Схема сборки карданного вала FAW в свой 5 типы обслуживаемых компонентов, including the ‘Inter-axle driveshaft’ (2205010A91W), the ‘Rear-axle driveshaft’ (2201010-1050), and the critical high-torque fasteners that secure them.
The ‘Rear-axle driveshaft & universal joint assembly’ (2201010-1050), despite its name, is the **main driveshaft**. It is the primary component in the Схема сборки карданного вала FAW that connects the transmission’s output flange to the “вперед” (или “середина”) drive axle’s input flange.
This component is a precision-engineered, hollow steel tube. It must be both incredibly strong (to handle the engine’s full torque) and perfectly balanced. Any imbalance in this long, high-speed shaft would create a severe, speed-dependent vibration that would shake the entire truck and destroy the transmission’s output bearing. It is dynamically balanced at the factory to a very high tolerance.
A critical design element is its “critical speed”—the RPM at which a shaft’s own harmonic frequency will cause it to wobble violently, like a jump rope. Этот Схема сборки карданного вала FAW component is engineered with a specific diameter and wall thickness to ensure its critical speed is far higher than the truck will ever achieve.
The ‘Inter-axle driveshaft & universal joint assembly’ (2205010A91W) is the second shaft in this 6×4 система. Это “inter-axle” вал, a key part of the Схема сборки карданного вала FAW. Its job is to connect the “выход” of the forward-most drive axle to the “вход” of the rear-most drive axle.
This allows the engine’s torque to be “passed through” the first axle to power the second, ensuring all four sets of rear wheels are driven (а “4” in 6×4). This short, high-torque shaft must handle the same immense forces as the main shaft.
Both this shaft and the main shaft are listed as an “сборка” because they come as a complete, non-serviceable unit with the ‘Universal Joint Assemblies’ (U-Joints) factory-installed and balanced. A failure of a U-joint on this Схема сборки карданного вала FAW component typically requires the replacement of the entire shaft assembly.
The “логика” принадлежащий Схема сборки карданного вала FAW is embodied by its universal joints, which are included in the shaft assemblies. A U-joint is a simple, brilliant piece of engineering that allows a shaft to transmit full rotational power even when it is bent at an angle.
This is necessary because the transmission is fixed to the engine, while the drive axles are on the suspension, constantly moving up and down. The angle between the transmission and the axle is never the same. A U-joint solves this by acting as a “double-hinge.”
It consists of a central “cross” или “паук” with four precision-ground trunnions (оружие). Each trunnion is fitted with a “cap” containing needle-roller bearings. These four caps are then bolted into the “yokes” (the U-shaped ends) of the two shafts. Это позволяет Схема сборки карданного вала FAW к “сгибать” in two axes (up/down and left/right) одновременно, all while spinning at thousands of RPM.
A critical aspect of the Схема сборки карданного вала FAW is **”phasing.”** The yokes at both ends of a single shaft must be installed in perfect alignment. If they are “out of phase” (misaligned), the U-joints will not cancel each other’s vibrations, leading to a severe “содрогаться” on acceleration and rapid failure.
The primary failure mode for a U-joint in the Схема сборки карданного вала FAW is lack of lubrication. The needle bearings inside the caps require periodic greasing. If they run dry, they will be destroyed by friction, causing a “chirping” шум (that varies with road speed) или “стук” при переключении с передачи на задний ход. A seized U-joint will cause a catastrophic failure, often breaking the driveshaft and potentially damaging the transmission housing.
The Схема сборки карданного вала FAW lists a large quantity of specialized, high-strength hardware. This is because the entire torque of the engine is transmitted through these few bolts.
**Болты (Q1851455T & Q1851450T):** Список требует 8 ‘Hex head flange bolts’ (Q1851455T) и 8 ‘Hex head flange bolts’ (Q1851450T). This is a total of 16 болты. This makes perfect sense for a two-shaft system:
Это “фланец” болты, и “Т” suffix indicates they are high-tensile (НАПРИМЕР., Сорт 10.9 или 12.9) and designed to withstand extreme “сдвигать” силы. The two different part numbers refer to different lengths, as the transmission flange and axle flanges may have different thicknesses.
**Орехи (Q32914):** The ‘Type 1 non-metallic insert hex lock nut’ (Q32914) is the final piece of the Схема сборки карданного вала FAW. Список требует 16 nuts to match the 16 болты. Это “Найлок” орехи. The nylon insert at the top of the nut creates a “преобладающий крутящий момент,” which grips the bolt threads and prevents the nut from *ever* vibrating loose. Это критический момент, single-use safety feature. These nuts must be replaced every time they are removed to ensure the Схема сборки карданного вала FAW остается в безопасности.
