Conjunto lógico de montaje auxiliar de transmisión FAW: Un enfoque experto en 17 Componentes críticos

Bienvenido a esta guía técnica experta sobre el Conjunto lógico de montaje auxiliar de transmisión FAW. este es el completo, heavy-duty support system for the main gearbox, Diseñado para FAW Jiefang CA4251P66K24T1A3E5 6×4 tractor semirremolque diésel. This assembly is not the transmission itself, but the critical “suspensión” that holds it.

El Conjunto lógico de montaje auxiliar de transmisión FAW provides the main structural support for the rear of the heavy transmission, connecting it to the truck’s chassis frame rails. Es “lógica” es proporcionar una rigidez, 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. Deconstruiremos todo Conjunto lógico de montaje auxiliar de transmisión FAW en su 17 componentes reparables, including the main ‘Crossbeam’ (1706061-95Ud.), the ‘Flexible Cushion Assemblies’ (1704150-5h), y todos los soportes y sujetadores críticos.

Estructura central: The Crossbeam Assembly (1706061-95Ud.)

The backbone of the entire Conjunto lógico de montaje auxiliar de transmisión FAW is the ‘Crossbeam-transmission auxiliary mounting crossbeam assy’ (1706061-95Ud.). This is the primary structural member, un masivo, 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 “escenario” upon which all other components of the Conjunto lógico de montaje auxiliar de transmisión FAW are built. Its function is to bear the entire static weight of the rear of the transmission (which can be several hundred kilograms) y, más 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.

Lado del chasis: The Fixed Bracket Assemblies

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

Estos son resistentes, 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 (soporte + crossbeam) es una parte clave de la Conjunto lógico de montaje auxiliar de transmisión 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, varilla gruesa (Tipo estándar)’ (Q1841440) and ‘Large washer’ (Q40214) hardware. todo el Conjunto lógico de montaje auxiliar de transmisión FAW relies on this rigid, no-flex connection to the chassis.

El “Lógica”: Flexible Cushion Assembly (1704150-5h)

el mas critico “lógica” del Conjunto lógico de montaje auxiliar de transmisión FAW lies in the ‘Transmission mounting flexible cushion assy’ (1704150-5h). La lista de piezas requiere cuatro de estos.. Estos son los principales “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.

Estos “flexible cushions” are the solution. Each one is a “sándwich” 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, Sucesivamente, rest on the main ‘Crossbeam’ (1706061-95Ud.).

The rubber in these mounts is designed to absorb and “humedecer” the high-frequency vibrations of the powertrain, while still being stiff enough to resist the “push-pull” of torque. A failed cushion (P.EJ., collapsed or “de-bonded” goma) is a critical failure of the Conjunto lógico de montaje auxiliar de transmisión FAW, resulting in a severe “ruido sordo” on acceleration and excessive vibration in the cab. todo el Conjunto lógico de montaje auxiliar de transmisión FAW is designed around these four cushions.

Juntas, Platos, and Sleeves

para apoyar el “flexible cushion” lógica, el Conjunto lógico de montaje auxiliar de transmisión FAW uses several other components. The ‘Gasket block-transmission auxiliary mounting bracket’ (1706073-91W.) and ‘Gasket plate-transmission auxiliary support crossbeam assy’ (1706062-48A) are critical insulators.

These pads (o “juntas”) are made of a dense polymer or rubber. They are placed between the steel mounting brackets (P.EJ., 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 montaje auxiliar de transmisión FAWel diseño.

Sujetadores críticos: The Locking Pin System

El Conjunto lógico de montaje auxiliar de transmisión FAW is a high-vibration area, and a loose fastener is not an option. The list details a critical “no puedo fallar” locking system for the main support pins.

The ‘Hex head bolt with hole’ (CQ17716110), de los cuales hay dos, are special bolts. They are used to secure the ‘Left’ y 'correcto’ 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 “piernas” 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. Este “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 montaje auxiliar de transmisión FAW‘s robust design.
