Логический узел крепления коробки передач FAW: Критический взгляд на 4 Ключевые компоненты поддержки

Добро пожаловать в это важное техническое руководство по Логический узел крепления коробки передач FAW. Это полный, heavy-duty rear support system for the manual transmission, designed specifically for the FAW Jiefang CA4251P66K24T1A3E5 6×4 дизельный полуприцеп тягач. This system is the structural “колыбель” that supports the entire weight of the gearbox and isolates it from the chassis.

The Логический узел крепления коробки передач FAW is not the transmission itself, but rather the set of “Левый” (1706051A91W) и “Верно” (1706052A91W) brackets that bolt to the rear of the gearbox. These brackets then rest on the chassis crossmember (см. сборку 323), providing a flexible, vibration-damped connection.

This in-depth guide is an essential resource for professional chassis technicians, менеджеры автопарка, и специалисты по запчастям. Мы разберем всю Логический узел крепления коробки передач FAW в свой 4 исправные компоненты, explaining the function of each bracket and the critical, high-tensile flange bolts used to secure them against the immense torque and vibration of a heavy-duty powertrain.

Основные компоненты: Левый (1706051A91W) & Верно (1706052A91W) Кронштейны

Сердце Логический узел крепления коробки передач FAW consists of a symmetrical pair of heavy-duty support brackets:

• **’Transmission mounting left bracket’ (1706051A91W):** This is the main support arm for the left-hand side of the gearbox.
• **’Transmission mounting right bracket’ (1706052A91W):** This is the symmetrical counterpart for the right-hand side.

Это не просто “л” скобки. Они массивные, complex castings, typically made from high-strength ductile iron or fabricated steel. They are heavily ribbed and gusseted to provide maximum rigidity against “torque-twist.” Their primary function is to act as the “feet” передачи. They bolt directly to the sides of the transmission’s rear housing (the auxiliary “дополнительный ящик”).

The “логика” этого Логический узел крепления коробки передач FAW is to provide a wide, stable platform. The flat, lower surfaces of these brackets are what rest on top of the ‘Transmission mounting flexible cushion assy’ (the large rubber mounts, detailed in Assembly 323). Этот “bracket-on-cushion” design is what isolates the powertrain from the chassis, which is the entire purpose of a modern Логический узел крепления коробки передач FAW.

A crack or failure in one of these brackets is a catastrophic structural failure. It would cause the entire rear of the transmission to “провисать” or drop. This would immediately misalign the entire driveline, changing the driveshaft’s “U-joint angles,” which would cause severe vibration, and eventual failure of the U-joints, center support bearing, or the transmission’s output shaft bearing. Целостность этого Логический узел крепления коробки передач FAW is therefore critical to the entire driveline.

Система крепления: Heavy-Duty Flange Bolts

The final two components of the Логический узел крепления коробки передач FAW are the high-tensile fasteners that secure the brackets to the transmission housing. A mount is only as strong as its bolts.

The parts list calls for two different bolt sizes, итого 10 болты:

• **’Hex head flange bolt’ (Q1851650T):** 6 единицы.
• **’Hex head flange bolt’ (Q1851670T):** 4 единицы.

Это не стандартное оборудование. The “фланец” head is an integrated washer. This is a critical design choice for mounting a steel bracket to an (often) aluminum transmission housing. The wide flange distributes the immense clamping force over a larger surface area, preventing the hard steel bolt from “копаться в” или “растрескивание” the softer aluminum casing.

The “Т” suffix on these bolts (НАПРИМЕР., Q1851650**T**) indicates a specific high-tensile strength class (НАПРИМЕР., 10.9) and a specialized, антикоррозийное покрытие. These bolts must endure the constant, multi-axis “сдвигать” forces from the engine’s torque. The different part numbers (-1650T vs -1670T) indicate different lengths, which are required for the different thicknesses of the transmission casing’s mounting bosses.

Использование правильных, factory-specified, high-tensile flange bolts is the only way to ensure the Логический узел крепления коробки передач FAW remains securely attached to the gearbox. A loose or failed bolt would cause the entire transmission to become unsupported, приводящие к катастрофическому провалу. The Логический узел крепления коробки передач FAW relies on this hardware.
