Блок вспомогательной монтажной логики коробки передач FAW: Экспертный фокус на 17 Критические компоненты

Добро пожаловать в это экспертное техническое руководство по Блок вспомогательной монтажной логики коробки передач FAW. Это полный, heavy-duty support system for the main gearbox, designed for the FAW Jiefang CA4251P66K24T1A3E5 6×4 дизельный полуприцеп тягач. This assembly is not the transmission itself, but the critical “приостановка” that holds it.

The Блок вспомогательной монтажной логики коробки передач FAW provides the main structural support for the rear of the heavy transmission, connecting it to the truck’s chassis frame rails. Его “логика” is to provide a rigid, unyielding brace against engine torque while simultaneously isolating the cab from drivetrain vibration.

This in-depth guide is an essential resource for professional chassis technicians and fleet managers. Мы разберем всю Блок вспомогательной монтажной логики коробки передач FAW в свой 17 исправные компоненты, including the main ‘Crossbeam’ (1706061-95ты), the ‘Flexible Cushion Assemblies’ (1704150-5ЧАС), and all the critical brackets and fasteners.

Core Structure: The Crossbeam Assembly (1706061-95ты)

The backbone of the entire Блок вспомогательной монтажной логики коробки передач FAW is the ‘Crossbeam-transmission auxiliary mounting crossbeam assy’ (1706061-95ты). This is the primary structural member, a massive, heavy-gauge steel crossbeam that spans the two main frame rails of the truck’s chassis, passing directly underneath the transmission.

This crossbeam is the “stage” upon which all other components of the Блок вспомогательной монтажной логики коробки передач FAW are built. Its function is to bear the entire static weight of the rear of the transmission (which can be several hundred kilograms) и, что еще более важно, to resist the immense rotational “torque-twist” of the powertrain when the driver accelerates. A crack or bend in this crossbeam would compromise the entire driveline angle and is a critical structural failure.

Сторона шасси: The Fixed Bracket Assemblies

The ‘Crossbeam’ (1706061-95ты) connects to the truck’s main frame rails via a set of fixed brackets. This parts list details the ‘Left fixed bracket-transmission auxiliary mounting crossbeam assy’ (1706063-95ты) and the ‘Right fixed bracket-transmission auxiliary mounting crossbeam’ (1706064-95ты).

These are heavy-duty, forged or fabricated steel brackets. They act as the non-moving interface, bolting directly to the side of the truck’s C-channel frame rail. The crossbeam is then bolted to these brackets. This multi-piece design (кронштейн + crossbeam) is a key part of the Блок вспомогательной монтажной логики коробки передач FAW “логика,” as it allows for easier installation and service compared to a single, full-width welded unit.

These fixed brackets are secured to the frame with the ‘Hex flange bolt, грубый стержень (Стандартный тип)’ (Q1841440) and ‘Large washer’ (Q40214) hardware. Весь Блок вспомогательной монтажной логики коробки передач FAW relies on this rigid, no-flex connection to the chassis.

The “Логика”: Flexible Cushion Assembly (1704150-5ЧАС)

The most critical “логика” принадлежащий Блок вспомогательной монтажной логики коробки передач FAW lies in the ‘Transmission mounting flexible cushion assy’ (1704150-5ЧАС). The parts list calls for four of these. These are the main “transmission mounts,” or vibration isolators.

It is a common mistake to think the engine and transmission should be bolted rigidly to the frame. This would transmit 100% of the engine’s vibration directly into the chassis and cab, resulting in an unbearably loud, bone-jarring ride and causing metal components to fatigue and crack.

Эти “flexible cushions” are the solution. Each one is a “бутерброд” of high-strength steel and a large block of specially-engineered rubber (elastomer). The ‘Left auxiliary support bracket’ (1706071-97В) and ‘Right auxiliary support bracket’ (1706072-97В) bolt to the transmission itself. These brackets then rest *on* these four flexible cushions. The cushions, по очереди, rest on the main ‘Crossbeam’ (1706061-95ты).

The rubber in these mounts is designed to absorb and “dampen” the high-frequency vibrations of the powertrain, while still being stiff enough to resist the “двухтактный” of torque. A failed cushion (НАПРИМЕР., collapsed or “de-bonded” резина) is a critical failure of the Блок вспомогательной монтажной логики коробки передач FAW, resulting in a severe “clunk” on acceleration and excessive vibration in the cab. Весь Блок вспомогательной монтажной логики коробки передач FAW is designed around these four cushions.

Прокладки, Plates, and Sleeves

To support the “flexible cushion” логика, а Блок вспомогательной монтажной логики коробки передач FAW uses several other components. The ‘Gasket block-transmission auxiliary mounting bracket’ (1706073-91Вт) and ‘Gasket plate-transmission auxiliary support crossbeam assy’ (1706062-48А) are critical insulators.

These pads (или “прокладки”) are made of a dense polymer or rubber. They are placed between the steel mounting brackets (НАПРИМЕР., 1706071-97В) and the transmission housing. This prevents any direct metal-on-metal contact, which would transmit noise and vibration, bypassing the main cushions.

The ‘Support sleeve’ (1704166-5ЧАС) is a steel tube that passes *through* the center of the ‘Flexible cushion’ (1704150-5ЧАС). This is a critical component that acts as a “stop.” It allows the technician to tighten the main mounting bolts (like Q1841455T) with full torque, making the steel-on-steel connection (bolt-to-sleeve-to-bracket) rigid, *without* “crushing” the rubber of the flexible cushion. This is the key to the entire Блок вспомогательной монтажной логики коробки передач FAW‘s design.

Критические крепежи: The Locking Pin System

The Блок вспомогательной монтажной логики коробки передач FAW is a high-vibration area, and a loose fastener is not an option. The list details a critical “не может потерпеть неудачу” locking system for the main support pins.

The ‘Hex head bolt with hole’ (CQ17716110), из них два, are special bolts. They are used to secure the ‘Left’ и «Правильно’ auxiliary support brackets to the transmission. As the name implies, a hole is drilled through the bolt’s head.

After this bolt is torqued to its final specification, the ‘Cotter pin’ (Q5003040) is inserted through this hole and its “legs” are bent over. This small pin acts as a 100% positive, physical lock. It makes it mechanically impossible for the bolt to vibrate loose and back out. Этот “bolt-and-castle-nut-with-pin” логика (though here it’s a bolt-with-pin) is the ultimate in safety and is a hallmark of the Блок вспомогательной монтажной логики коробки передач FAW‘s robust design.
