Conjunto de lógica de control de transmisión FAW: Un enfoque integral en 50 Componentes reparables

Bienvenido a esta completa guía técnica sobre el Conjunto de lógica de control de transmisión FAW (without PTO). este es el completo, multi-part driver interface and linkage system for the manual transmission in the FAW Jiefang CA4251P66K24T1A3E5 6×4 tractor semirremolque diésel.

El Conjunto de lógica de control de transmisión FAW es el conjunto “palanca de cambios” sistema, responsible for translating the driver’s hand movements into precise, mechanical gear selection inside the gearbox. It includes the in-cab ‘Transmission control handle’ (1703025A91W-C00), the ‘Transmission control rod’ (1703021A61B), and the extensive network of linkages, paréntesis, and pneumatic pipes that connect the cab to the transmission.

Esta guía detallada es un recurso fundamental para técnicos profesionales y administradores de flotas.. Deconstruiremos todo Conjunto de lógica de control de transmisión FAW en su 50 componentes reparables, detailing the function of the in-cab shifter, the critical floor seal, the vibration-damping “almohadilla suave” sistema, the pneumatic range-shifter pipes, and the final mechanical linkages.

La interfaz del conductor: Shifter Handle and Ball Joint

El Conjunto de lógica de control de transmisión FAW begins inside the cab. The ‘Transmission control handle & gear plate assy’ (1703025A91W-C00) is the component the driver holds. This assembly includes the gear knob (with the shift pattern) and the upper rod, o “stick.”

This stick pivots on a ‘Ball pin-transmission control rod’ (1703013C70A). This precision-machined ball joint is the heart of the shifter’s “feel.” It is housed within a ‘Bushing’ (1703011C70A) and ‘Rear gasket’ (1703012C70A) to provide a smooth, low-friction pivot point.

This entire joint is protected from cab-side dust and spills by the ‘Ball pin cover’ (1703016C70A) and the ‘Sealing cover-transmission control rod’ (1703018C70A), which is held in place by a ‘Clamping spring’ (1703019C70A). This sealed, precise joint is the first stage in the Conjunto de lógica de control de transmisión FAW, translating the driver’s “patrón H” movements into precise fore-aft and side-to-side motion.

Cab Sealing: The Floor Seal and Dust Cover System

A critical part of the Conjunto de lógica de control de transmisión FAW es el “cab-floor interface.” This is a complex seal designed to completely isolate the driver’s cab from the noise, humos, calor, and road grime of the chassis below.

This system is centered on the ‘Sealing seat assy-cab floor’ (1703030-61B). Este es un gran, molded rubber boot or “asiento” that creates the main seal against the cab’s floor pan. It is secured by a ‘Buckle-sealing seat assy’ (1703036A70A).

Este “asiento” protects a dual-layer ‘Dust cover’ sistema. The ‘Upper dust cover’ (1703041-61B) and ‘Lower dust cover’ (1703046-61B) form a “bellows” that can flex as the shifter moves. These are held in place by the ‘Upper support plate’ (1703061A70A), ‘Lower support plate’ (1703060-61C), and their respective ‘Buckles’ (1703043A70A, 1703048A70A). A tear in this boot system is a major issue, conduciendo a un fuerte, caliente, and fume-filled cab. This sealing system is a vital, non-mechanical part of the Conjunto de lógica de control de transmisión FAW.

Aislamiento de vibraciones: El “Soft Pad” Sistema de amortiguación

The transmission and engine vibrate intensely, while the cab is “paseo aéreo” o “rubber-mounted” to be still. El Conjunto de lógica de control de transmisión FAW must bridge this gap without transferring the vibration to the driver’s hand. This is achieved with a sophisticated “almohadilla suave” damping system.

The parts list calls for eight ‘Soft pad seat’ (1703076A70A), eight ‘Soft pad’ (1703077A70A), and eight ‘Gasket’ (1703079A70A) unidades. These components create eight complete rubber “shock absorbers.” They are used to mount the ‘Transmission control rod bracket’ (1703071-91W.) al chasis.

The ‘Sleeve-transmission control rod upper bracket’ (1703078-74A) units act as steel cores for these mounts. This entire sub-assembly “flota” the shifter bracket on these 8 rubber pads, completely isolating the ‘Transmission control rod’ (1703021A61B) from high-frequency “buzzing.” The ‘Soft pad assy-transmission control rod’ (1703085-61B) provides further damping, asegurando el Conjunto de lógica de control de transmisión FAW feels solid and comfortable, not like a vibrating piece of machinery.

Lógica Neumática: The Range/Splitter Control Piping

Este Conjunto de lógica de control de transmisión FAW controls a 12-speed (o más) transmisión, which requires a “rango” o “disidente” selection. This is not done mechanically, but pneumatically (with air). The ‘Transmission control pipe bundle assy’ (1703330-99A) is a set of pre-bent, color-coded air lines.

When the driver flips the range-selector switch on the gear knob, it sends an electrical signal to a solenoid valve block (see assembly 155). That block then sends high-pressure air through this ‘Pipe bundle’ to the ‘FAW Auxiliary Cylinder Assembly’ (see assembly 168), which physically shifts the sub-box.

The ‘Intake pipe assy-transmission’ (1703640-52W.) and ‘Terminal-type pipe joint assy’ (1703610-1500) are the main “supply” lines that feed compressed air into this control system. A leak in any of these air lines is a critical failure of the Conjunto de lógica de control de transmisión FAW, as it will leave the driver unable to select half of their gears (P.EJ., stuck in “Rango bajo”).

The Mechanical Linkage: Rods, Brazos, and Brackets

The final part of the Conjunto de lógica de control de transmisión FAW is the set of heavy-duty rods that create the final mechanical connection. The ‘Transmission control longitudinal rod with connector assy’ (1703095-91W.) es el principal “push-pull” rod that connects the in-cab shifter to the transmission.

This rod actuates the ‘Rear joint assy-transmission control arm’ (1703145A70A), which is the lever that physically enters the transmission’s “tapa superior” (see assembly 153). This connection is made via the ‘Fixed arm connecting rod & conjunto conjunto’ (1703110-56A).

These rods are held in place and guided by various brackets, including the ‘Main wiring harness bracket’ (3724426-68V), which doubles as a support. The bushings (‘Sleeve’ 1703081A92W, 1703082-61B, 1703083-61B) son críticos, as they prevent “agua sucia” o “jugar” in the linkage, ensuring a precise and confident gear shift. todo el Conjunto de lógica de control de transmisión FAW is a precision system from start to finish.
