Блок логики управления коробкой передач FAW: Комплексное внимание к 50 Обслуживаемые компоненты

Добро пожаловать в это подробное техническое руководство по Блок логики управления коробкой передач FAW (without PTO). Это полный, multi-part driver interface and linkage system for the manual transmission in the FAW Jiefang CA4251P66K24T1A3E5 6×4 дизельный полуприцеп тягач.

The Блок логики управления коробкой передач FAW is the entire “оборотень” система, 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’ (1703021А61Б), and the extensive network of linkages, скобки, and pneumatic pipes that connect the cab to the transmission.

This in-depth guide is a critical resource for professional technicians and fleet managers. Мы разберем всю Блок логики управления коробкой передач FAW в свой 50 исправные компоненты, detailing the function of the in-cab shifter, the critical floor seal, the vibration-damping “мягкая подушечка” система, the pneumatic range-shifter pipes, and the final mechanical linkages.

The Driver Interface: Shifter Handle and Ball Joint

The Блок логики управления коробкой передач 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, или “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) обеспечить плавный, 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 Блок логики управления коробкой передач FAW, translating the driver’s “H-pattern” movements into precise fore-aft and side-to-side motion.

Cab Sealing: The Floor Seal and Dust Cover System

A critical part of the Блок логики управления коробкой передач FAW это “cab-floor interface.” This is a complex seal designed to completely isolate the driver’s cab from the noise, fumes, нагревать, and road grime of the chassis below.

This system is centered on the ‘Sealing seat assy-cab floor’ (1703030-61Б). Это большой, molded rubber boot or “сиденье” that creates the main seal against the cab’s floor pan. It is secured by a ‘Buckle-sealing seat assy’ (1703036А70А).

Этот “сиденье” protects a dual-layer ‘Dust cover’ система. The ‘Upper dust cover’ (1703041-61Б) and ‘Lower dust cover’ (1703046-61Б) form a “сильфоны” that can flex as the shifter moves. These are held in place by the ‘Upper support plate’ (1703061А70А), ‘Lower support plate’ (1703060-61С), and their respective ‘Buckles’ (1703043А70А, 1703048А70А). A tear in this boot system is a major issue, leading to a loud, горячий, and fume-filled cab. This sealing system is a vital, non-mechanical part of the Блок логики управления коробкой передач FAW.

Виброизоляция: The “Soft Pad” Система демпфирования

The transmission and engine vibrate intensely, while the cab is “air-ride” или “rubber-mounted” to be still. The Блок логики управления коробкой передач FAW must bridge this gap without transferring the vibration to the driver’s hand. This is achieved with a sophisticated “мягкая подушечка” damping system.

The parts list calls for eight ‘Soft pad seat’ (1703076А70А), eight ‘Soft pad’ (1703077А70А), and eight ‘Gasket’ (1703079А70А) единицы. These components create eight complete rubber “shock absorbers.” They are used to mount the ‘Transmission control rod bracket’ (1703071-91Вт) к шасси.

The ‘Sleeve-transmission control rod upper bracket’ (1703078-74А) units act as steel cores for these mounts. This entire sub-assembly “плавает” the shifter bracket on these 8 rubber pads, completely isolating the ‘Transmission control rod’ (1703021А61Б) from high-frequency “buzzing.” The ‘Soft pad assy-transmission control rod’ (1703085-61Б) provides further damping, обеспечение Блок логики управления коробкой передач FAW feels solid and comfortable, not like a vibrating piece of machinery.

Пневматическая логика: The Range/Splitter Control Piping

Этот Блок логики управления коробкой передач FAW controls a 12-speed (или больше) передача инфекции, which requires a “диапазон” или “splitter” selection. This is not done mechanically, but pneumatically (with air). The ‘Transmission control pipe bundle assy’ (1703330-99А) 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 (см. сборку 155). That block then sends high-pressure air through this ‘Pipe bundle’ to the ‘FAW Auxiliary Cylinder Assembly’ (см. сборку 168), which physically shifts the sub-box.

The ‘Intake pipe assy-transmission’ (1703640-52Вт) and ‘Terminal-type pipe joint assy’ (1703610-1500) являются основными “supply” lines that feed compressed air into this control system. A leak in any of these air lines is a critical failure of the Блок логики управления коробкой передач FAW, as it will leave the driver unable to select half of their gears (НАПРИМЕР., stuck in “Низкий диапазон”).

The Mechanical Linkage: Rods, Arms, и скобки

The final part of the Блок логики управления коробкой передач FAW is the set of heavy-duty rods that create the final mechanical connection. The ‘Transmission control longitudinal rod with connector assy’ (1703095-91Вт) является основным “двухтактный” rod that connects the in-cab shifter to the transmission.

This rod actuates the ‘Rear joint assy-transmission control arm’ (1703145А70А), which is the lever that physically enters the transmission’s “верхняя крышка” (см. сборку 153). This connection is made via the ‘Fixed arm connecting rod & сустав в сборе’ (1703110-56А).

These rods are held in place and guided by various brackets, including the ‘Main wiring harness bracket’ (3724426-68В), which doubles as a support. The bushings (‘Sleeve’ 1703081A92W, 1703082-61Б, 1703083-61Б) имеют решающее значение, as they prevent “помои” или “играть” in the linkage, ensuring a precise and confident gear shift. Весь Блок логики управления коробкой передач FAW is a precision system from start to finish.
