Conjunto lógico de montagem auxiliar de transmissão FAW: Um foco especializado em 17 Componentes críticos

Bem-vindo a este guia técnico especializado sobre o Conjunto lógico de montagem auxiliar de transmissão FAW. Este é o completo, heavy-duty support system for the main gearbox, projetado para o FAW Jiefang CA4251P66K24T1A3E5 6×4 trator semirreboque diesel. This assembly is not the transmission itself, but the critical “suspensão” that holds it.

O Conjunto lógico de montagem auxiliar de transmissão FAW provides the main structural support for the rear of the heavy transmission, connecting it to the truck’s chassis frame rails. Isso é “lógica” é fornecer uma rígida, unyielding brace against engine torque while simultaneously isolating the cab from drivetrain vibration.

Este guia detalhado é um recurso essencial para técnicos profissionais de chassis e gerentes de frota. Vamos desconstruir todo Conjunto lógico de montagem auxiliar de transmissão FAW em seu 17 componentes reparáveis, including the main ‘Crossbeam’ (1706061-95U), the ‘Flexible Cushion Assemblies’ (1704150-5H), and all the critical brackets and fasteners.

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

The backbone of the entire Conjunto lógico de montagem auxiliar de transmissão FAW is the ‘Crossbeam-transmission auxiliary mounting crossbeam assy’ (1706061-95U). This is the primary structural member, um enorme, 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 Conjunto lógico de montagem auxiliar de transmissão FAW are built. Its function is to bear the entire static weight of the rear of the transmission (which can be several hundred kilograms) e, mais importante, 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.

Chassis-Side: The Fixed Bracket Assemblies

The ‘Crossbeam’ (1706061-95U) 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’ (1706063-95U) and the ‘Right fixed bracket-transmission auxiliary mounting crossbeam’ (1706064-95U).

Estes são pesados, 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 (suporte + crossbeam) é uma parte fundamental do Conjunto lógico de montagem auxiliar de transmissão FAW “lógica,” 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, haste grossa (Tipo padrão)’ (Q1841440) and ‘Large washer’ (Q40214) hardware. O inteiro Conjunto lógico de montagem auxiliar de transmissão FAW relies on this rigid, no-flex connection to the chassis.

O “Lógica”: Flexible Cushion Assembly (1704150-5H)

O mais crítico “lógica” do Conjunto lógico de montagem auxiliar de transmissão FAW lies in the ‘Transmission mounting flexible cushion assy’ (1704150-5H). A lista de peças pede quatro destes. 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.

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

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 “empurrar-puxar” of torque. A failed cushion (Por exemplo, collapsed or “de-bonded” borracha) is a critical failure of the Conjunto lógico de montagem auxiliar de transmissão FAW, resulting in a severe “barulho” on acceleration and excessive vibration in the cab. O inteiro Conjunto lógico de montagem auxiliar de transmissão FAW is designed around these four cushions.

Juntas, Pratos, and Sleeves

To support the “flexible cushion” lógica, o Conjunto lógico de montagem auxiliar de transmissão FAW uses several other components. The ‘Gasket block-transmission auxiliary mounting bracket’ (1706073-91C) and ‘Gasket plate-transmission auxiliary support crossbeam assy’ (1706062-48A) are critical insulators.

These pads (ou “Juntas”) are made of a dense polymer or rubber. They are placed between the steel mounting brackets (Por exemplo, 1706071-97V) 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’ (1704166-5H) is a steel tube that passes *through* the center of the ‘Flexible cushion’ (1704150-5H). 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) rígido, *without* “crushing” the rubber of the flexible cushion. This is the key to the entire Conjunto lógico de montagem auxiliar de transmissão FAWprojeto.

Fixadores Críticos: The Locking Pin System

O Conjunto lógico de montagem auxiliar de transmissão FAW is a high-vibration area, and a loose fastener is not an option. The list details a critical “cannot-fail” locking system for the main support pins.

The ‘Hex head bolt with hole’ (CQ17716110), dos quais existem dois, are special bolts. They are used to secure the ‘Left’ e 'Certo’ 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% positivo, physical lock. It makes it mechanically impossible for the bolt to vibrate loose and back out. Esse “bolt-and-castle-nut-with-pin” lógica (though here it’s a bolt-with-pin) is the ultimate in safety and is a hallmark of the Conjunto lógico de montagem auxiliar de transmissão FAW‘s robust design.
