Корпус коробки передач FAW J6P: Деконструкция 29 Основные детали для структурной целостности

Welcome to this expert analysis of the Корпус коробки передач FAW J6P, the foundational structure for the CA10TA160M transmission in the FAW Jiefang CA3250P66K2L1T1E 6×4 самосвал. Это руководство предназначено для технических специалистов, breaking down the 29 components that comprise the complete Корпус коробки передач FAW J6P and clutch housing assembly, from the main case to the smallest gasket.

The Корпус коробки передач FAW J6P is not just a “коробка”; it is a high-precision component responsible for perfect shaft alignment, oil sealing, and heat dissipation. Its structural integrity is the single most important factor for a long transmission service life. This guide will deconstruct this critical assembly into its functional subsystems.

Основной 1: The Main Structural Logic (The FAW J6P Gearbox Housing)

This group represents the core “шасси” of the entire transmission. All other components, internal and external, mount to this one part. The Корпус коробки передач FAW J6P is the literal foundation.

1. Компонент: ‘Gearbox body’ (1701031-A7G)
Этот (Комп 1) is the main case, the ‘Gearbox body’. This is the largest and most complex component, typically cast from high-strength iron or aluminum. Его логика тройственна.: alignment, уплотнение, and heat dissipation.

The Логика выравнивания это его самая важная функция. This main case has precisely bored holes for the input shaft, mainshaft, and countershaft(с) подшипники. These bores must be perfectly parallel. Any warping or damage to the Корпус коробки передач FAW J6P will cause shaft misalignment, leading to rapid gear and bearing failure.

The Логика уплотнения is its obvious function. It acts as a large “отстойник” или “oil bath” for the entire gear set. It is designed with multiple machined faces for gaskets (как Комп 3, 8, 21, 24) to create a leak-proof enclosure.

The Heat Dissipation Logic is also vital. Весь Корпус коробки передач FAW J6P acts as a giant heat sink. The hot transmission oil transfers its heat to the case, and the external fins (if present) and large surface area dissipate this heat to the surrounding air.

Основной 2: The “Clutch Interface” Логика (The Clutch Housing)

Этот компонент является “adapter” that connects the Корпус коробки передач FAW J6P to the engine. It is commonly known as the “bellhousing” and is a critical alignment component.

1. Компонент: ‘Clutch outer housing assy’ (1601010-A1K / 1601010D76A)
Этот (Комп 11) is the ‘Clutch Outer Housing Assembly’. This large, bell-shaped component bolts to the front of the ‘Gearbox body’ (Комп 1) and creates the “сухой” enclosure for the clutch assembly. The two part numbers indicate an option, likely based on the simultaneous selection of 1701112-A7G, as noted.

The Engine Interface Logic is its primary role. This housing bolts to the back of the engine block. Его “alignment” is ensured by ‘Dowel pins’ (Комп 2, `定位销-副箱売` – Positioning pin-auxiliary box housing), which precisely locate it relative to the engine’s crankshaft. This ensures the Корпус коробки передач FAW J6P input shaft is perfectly centered.

The Mechanism Mount Logic is its secondary role. This housing provides the mounting points for the clutch release fork and shaft (seen in the ‘Clutch Control Mechanism’ авария), allowing the external hydraulic force to be transferred inside. This part of the Корпус коробки передач FAW J6P is essential for clutch operation.

Основной 3: “Услуга & PTO Port” Логика (Covers & Plugs)

This group includes all the components designed to seal the various “порты” или “окна” on the main Корпус коробки передач FAW J6P. These ports allow for service, inspection, and the addition of auxiliary equipment.

1. The “PTO Port” Группа (Комп 8, 9, 23, 24)
В эту группу входят: ‘Gasket-PTO bottom port’ (Комп 8), ‘Cover-PTO bottom port’ (Комп 9), ‘Cover-PTO side port’ (Комп 23), and ‘Gasket-PTO side port’ (Комп 24).

The Modularity Logic is the purpose of these components. The Корпус коробки передач FAW J6P is cast with standardized, 6-bolt or 8-bolt “окна” (PTO ports) on its sides and/or bottom. This allows for the easy installation of a Power Take-Off (ВОМ) unit to run hydraulic pumps or other equipment.

Since this truck uses a flange-connected PTO (as seen in the main gearbox assembly), these *other* ports are not needed. Поэтому, simple ‘Covers’ and ‘Gaskets’ are used to securely seal them, preventing oil leaks from the Корпус коробки передач FAW J6P.

2. The “Service Port” Группа (Комп 4, 25)
В эту группу входят: ‘Oil drain plug assy’ (Комп 4) and ‘Magnet’ (Комп 25). The ‘Oil drain plug’ is the primary service point for draining the old gear oil from the Корпус коробки передач FAW J6P.

The Magnetic Logic is the function of the ‘Magnet’ (Комп 25). This magnet is either part of the ‘Oil drain plug assy’ or sits just inside it. Its critical job is to attract and capture any microscopic ferrous metal particles (from normal gear wear) circulating in the oil. Inspecting this magnet during an oil change is the best way to diagnose the internal health of the Корпус коробки передач FAW J6P.

Основной 4: “Несущий & Shaft Seal” Логика (The Covers)

This group of components is responsible for holding the main shaft bearings in place and, most importantly, sealing the rotating shafts as they exit the Корпус коробки передач FAW J6P.

1. Компоненты: ‘Bearing – первый вал’ (1701141-A7G) & ‘Cover – first shaft bearing’ (1701142-A7G)
Этот (Комп 16 & 19) является полным “input shaft” bearing and cover assembly. The ‘Bearing’ (Комп 16) is the main bearing that supports the input shaft, pressed into the front of the Корпус коробки передач FAW J6P.

The Bearing Retainer Logic is the function of the ‘Cover’ (Комп 19). This cover bolts to the front of the Корпус коробки передач FAW J6P (с помощью болтов Комп. 17 и 20). It has two jobs: 1) Он действует как “retainer,” physically holding the outer race of the bearing (Комп 16) and preventing it from moving. 2) It contains the all-important input shaft oil seal.

The Input Seal Logic is the most critical sealing function in the entire system. This seal (housed in Comp 19) is what keeps the high-temperature gear oil *inside* the Корпус коробки передач FAW J6P and keeps the “сухой” clutch housing free of oil. A failure of this one seal will immediately cause the clutch to slip and fail.

Основной 5: “Застежка & Уплотнение” Логика (All Hardware)

This final group includes all the specialized bolts, орехи, and gaskets used to assemble the Корпус коробки передач FAW J6P. Their logic is to provide precise alignment, secure clamping force, and leak-proof static sealing.

1. The “Alignment” Группа (Комп 2, 17, 20, 29)
This group includes ‘Dowel pin’ (Комп 2), ‘Hexagon head bolt with guide neck’ (Комп 17, 20), and ‘Cylindrical pin’ (Комп 29). The Precise Fit Logic является ключевым. Dowel pins align the main housing (Комп 1) to the clutch housing (Комп 11). The “guide neck” болты (Комп 17, 20) are used to perfectly align the ‘First shaft bearing cover’ (Комп 19) before the threads engage. This precision is non-negotiable for the Корпус коробки передач FAW J6P.

2. The “Зажим” Группа (Комп 10, 12, 14, 15, 22, 27, 28)
This is the main hardware for bolting the housings together. It includes ‘Hex flange bolts’ (Комп 10, 15, 22), ‘Double head bolts’ (Комп 12, 28), ‘Hex nuts’ (Комп 14), and ‘Type I all-metal hexagon flange locknuts’ (Комп 27).

The High-Tensile Logic of these fasteners ensures the entire Корпус коробки передач FAW J6P can withstand the immense torque and twisting forces from the engine and drivetrain. The “locknuts” (Комп 27) are special, one-time-use nuts that are deformed to create a mechanical lock, preventing them from ever backing off.

3. The “Уплотнение” Группа (Комп 3, 5, 8, 13, 18, 21, 24, 26)
This group includes all the static seals: «Прокладка’ (Комп 3, 21), «Втулка’ (Комп 5), ‘Gasket-PTO…’ (Комп 8, 24), «Пружинная шайба’ (Комп 13, 18), and ‘Large washer’ (Комп 26). The ‘Gaskets’ provide the primary paper/cork/metal seal between flat, machined surfaces of the Корпус коробки передач FAW J6P. The ‘Spring washers’ provide the anti-vibration logic, ensuring the bolts maintain clamping force.
