Welcome to this critical technical guide to the Diagrama de montagem do eixo de transmissão FAW. Esta montagem, também conhecido como “propeller shaft” ou “propshaft,” is the complete system for transmitting power from the transmission to the drive axles on the FAW Jiefang CA4251P66K24T1A3E5 6×4 trator semirreboque diesel.
O Diagrama de montagem do eixo de transmissão 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.
This in-depth guide is an essential resource for professional technicians and fleet managers. Vamos desconstruir todo Diagrama de montagem do eixo de transmissão FAW em seu 5 tipos de componentes utilizáveis, 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 Diagrama de montagem do eixo de transmissão FAW that connects the transmission’s output flange to the “avançar” (ou “meio”) 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. Esse Diagrama de montagem do eixo de transmissão 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 sistema. Este é o “entre eixos” haste, a key part of the Diagrama de montagem do eixo de transmissão FAW. Its job is to connect the “saída” of the forward-most drive axle to the “entrada” 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 (o “4” in 6×4). Este curto, high-torque shaft must handle the same immense forces as the main shaft.
Both this shaft and the main shaft are listed as an “conjunto” 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 Diagrama de montagem do eixo de transmissão FAW component typically requires the replacement of the entire shaft assembly.
O “lógica” do Diagrama de montagem do eixo de transmissão 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.”
É composto por uma central “cruzar” ou “aranha” with four precision-ground trunnions (braços). Each trunnion is fitted with a “boné” containing needle-roller bearings. These four caps are then bolted into the “jugos” (the U-shaped ends) of the two shafts. Isto permite que Diagrama de montagem do eixo de transmissão FAW para “dobrar” in two axes (up/down and left/right) simultaneously, all while spinning at thousands of RPM.
A critical aspect of the Diagrama de montagem do eixo de transmissão FAW is **”phasing.”** The yokes at both ends of a single shaft must be installed in perfect alignment. If they are “out of phase” (desalinhado), the U-joints will not cancel each other’s vibrations, leading to a severe “shudder” on acceleration and rapid failure.
The primary failure mode for a U-joint in the Diagrama de montagem do eixo de transmissão FAW is lack of lubrication. The needle bearings inside the caps require periodic greasing. If they run dry, eles serão destruídos pelo atrito, causando um “chilrear” barulho (that varies with road speed) ou um “barulho” when shifting from drive to reverse. A seized U-joint will cause a catastrophic failure, often breaking the driveshaft and potentially damaging the transmission housing.
O Diagrama de montagem do eixo de transmissão 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.
**Parafusos (Q1851455T & Q1851450T):** A lista pede 8 ‘Hex head flange bolts’ (Q1851455T) e 8 ‘Hex head flange bolts’ (Q1851450T). This is a total of 16 parafusos. This makes perfect sense for a two-shaft system:
Estes são “mesa” parafusos, e o “T” suffix indicates they are high-tensile (Por exemplo, Aula 10.9 ou 12.9) and designed to withstand extreme “cisalhar” forças. The two different part numbers refer to different lengths, as the transmission flange and axle flanges may have different thicknesses.
**Nozes (Q32914):** The ‘Type 1 non-metallic insert hex lock nut’ (Q32914) is the final piece of the Diagrama de montagem do eixo de transmissão FAW. A lista pede 16 nuts to match the 16 parafusos. Estes são “Nyloc” nozes. The nylon insert at the top of the nut creates a “prevailing torque,” which grips the bolt threads and prevents the nut from *ever* vibrating loose. Esta é uma crítica, single-use safety feature. These nuts must be replaced every time they are removed to ensure the Diagrama de montagem do eixo de transmissão FAW permanece seguro.
