Кольцо передней пружины FAW в сборе: Деконструкция 18 Критические компоненты

Добро пожаловать в это важное техническое руководство по Кольцо передней пружины FAW в сборе. Это полный “сковывать” и “приколоть” assembly for the rear mounting point of the front leaf springs on the FAW Jiefang CA4251P66K24T1A3E5 6×4 дизельный полуприцеп тягач. This assembly is the critical pivot point for the entire front suspension system.

The Кольцо передней пружины FAW в сборе, also known as the shackle, has a vital “логика.” It must allow the heavy-duty leaf spring to change its length as it flexes. When the spring compresses over a bump, it flattens and becomes *longer*. This shackle assembly acts as a swinging pivot, allowing for this elongation without binding the spring.

This in-depth guide is an essential resource for professional suspension technicians and parts specialists. Мы разберем всю Кольцо передней пружины FAW в сборе в свой 18 исправные компоненты, including the main ‘Hangers’ (shackles), the high-strength ‘Pins’, the ‘Grease fittings’, and the critical mounting hardware.

Основной компонент: The ‘Hanger’ (Серьга) (2902466A50A)

Сердце Кольцо передней пружины FAW в сборе is the ‘Hanger-Front Leaf Spring’ (2902466A50A). The parts list calls for two of these, one for each side of the vehicle. Этот компонент является “сковывать” сам. Это тяжелая работа, forged or cast steel “swinging link” that connects the rear “глаз” of the leaf spring to the truck’s main frame rail (via a fixed hanger bracket, not pictured).

The “логика” of this Кольцо передней пружины FAW в сборе is to manage spring elongation. A leaf spring is not a coil; it is an arc of steel. When the truck hits a bump, the spring compresses, causing this arc to flatten. As it flattens, its overall length from “eye-to-eye” increases. The front eye of the spring is in a fixed mount. This rear shackle must be able to pivot, или “swing” backward, to accommodate this increase in length.

Without this swinging “Hanger,” а Кольцо передней пружины FAW в сборе would be rigid. The first large bump would cause the leaf spring to bind and snap, or it would tear the spring hanger from the truck’s frame. These two ‘Hanger’ components are therefore essential for the suspension to articulate, handling the full weight of the front-end and absorbing the constant, violent forces from the road.

The Pivot: Shackle Pins (2902481-50А)

The ‘Hanger’ (сковывать) is a link, but it must pivot on something. This is the job of the ‘Pin-Front leaf spring rear bracket’ (2902481-50А). The parts list calls for four of these pins, which is a complete set for both sides of the truck (two pins per shackle).

One pin is used to connect the “вершина” of the shackle to the fixed frame bracket, and the other pin connects the “нижний” of the shackle to the “глаз” of the leaf spring. These pins are the “ось” или “hinges” принадлежащий Кольцо передней пружины FAW в сборе.

Это не простые болты. They are precision-ground, высокопрочный, case-hardened steel pins. They must be strong enough to withstand the “shear” force of the entire front-end load, and hard enough to resist wear from the constant pivoting motion. A worn or “ovaled” pin in the Кольцо передней пружины FAW в сборе will create a “лязг” noise on bumps and lead to “небрежный” steering and alignment issues.

The “Логика”: The Lubrication System (C070145)

Настоящий “логика” of this specific Кольцо передней пружины FAW в сборе is revealed by its serviceable design. The list calls for four ‘Bent neck grease fitting’ (C070145) компоненты. This is a 1:1 ratio with the four ‘Pins’ (2902481-50А).

This means the Кольцо передней пружины FAW в сборе is not a “sealed-for-life” единица. It is a **serviceable** assembly. The ‘Pins’ are drilled with grease channels, and these “grease fittings” (или “zerks”) are threaded into them. This allows a technician to use a grease gun to force heavy-duty chassis grease into the assembly as part of a regular maintenance schedule.

This lubrication logic is critical for two reasons:

1. **1. Lubrication:** The grease creates a high-pressure film between the steel ‘Pin’ и (unlisted, but implied) bronze or rubber bushings inside the shackle and spring eye. This allows the shackle to pivot smoothly and silently, preventing the “squeaking” и “groaning” common with dry leaf springs.
2. **2. Защита:** This is the most important function. The act of “purging” the joint with new grease forcefully pushes *out* the old, загрязненная смазка. This process expels the dirt, дорожная соль, and water that try to work their way into the joint. Без этого, the water would cause the pin to rust and “seize” inside its bushing.

A seized shackle pin is a critical failure of the Кольцо передней пружины FAW в сборе. It prevents the shackle from pivoting, which means the leaf spring can no longer elongate. This results in an incredibly harsh, unyielding ride and will, in a very short time, cause the leaf spring to snap or the main frame hanger to be torn off the chassis. Regular greasing of these 4 fittings is the most important maintenance task for the Кольцо передней пружины FAW в сборе.

The Foundation: Fastener System (CQ1511280 & CQ34112)

The final components of the Кольцо передней пружины FAW в сборе are the ‘Hex head bolt’ (CQ1511280) and ‘Hex nut’ (CQ34112) единицы. The list calls for four of each.

These are *not* the shackle pins. These are the heavy-duty fasteners (likely M12, 10.9-grade) that are used to mount the **fixed frame hanger** (the bracket that the *top* shackle pin pivots in) to the truck’s main C-channel frame rail.

Эти четыре болта (по два с каждой стороны) are the structural foundation of the entire Кольцо передней пружины FAW в сборе. They must be torqued to a precise specification to ensure the hanger bracket is rigidly attached to the frame. A loose hanger bracket, caused by failed or improperly torqued bolts, will create a “popping” шум, cause severe steering and alignment problems, and will quickly “oval” the bolt holes in the chassis, leading to a very expensive repair.
