Компоненты внутреннего контроля FAW: Внутри 32 Важные детали, влияющие на вашу трансмиссию

Добро пожаловать в это важное техническое руководство по Компоненты внутреннего контроля FAW, полный “shift logic” assembly for the manual transmission in the FAW Jiefang CA4251P66K24T1A3E5 6×4 дизельный полуприцеп тягач. This system is the “мозг” that translates the driver’s hand movement into mechanical gear selection.

The Компоненты внутреннего контроля FAW are not the gears themselves, but the entire “top-cover” assembly of forks, rails, and interlocks that physically move the synchronizer sleeves. When the driver moves the gear stick, they are moving this assembly, which in turn selects the desired gear.

This in-depth guide is an essential resource for professional transmission technicians. Мы разберем всю Компоненты внутреннего контроля FAW систему в свою 32 исправные части, including the shift forks for every gear, the shift rails (shafts) they ride on, and the critical interlock and detent mechanisms that ensure safe, precise shifting.

Основные компоненты: The Shift Fork System

The “мышца” принадлежащий Компоненты внутреннего контроля FAW is the set of shift forks. Это сверхмощные, кованая сталь “yokes” that ride in the grooves of the synchronizer sliding sleeves (as detailed in assembly 145). This parts list details the complete set:

• ‘Fork-1st, 2вторая передача’ (1702031-A9p)
• ‘Fork-3rd, 4th gear’ (1702041-A9p & 1702048-A9p)
• ‘Fork-5th, 6th gear’ (1702051-A9p, 1702053-A9p, 1702052-A9p)
• ‘Fork-reverse gear’ (1702067-A9p)

When the driver selects a gear, the gear lever (via the ‘Shaft-shift mechanism’ 1702078-A1K) selects one of these forks. The ‘Shaft-shift fork support’ (1702073-A9p) then slides this fork “вперед” или “backward.” This fork, по очереди, slides the synchronizer sleeve, который включает передачу. The ‘Fork-reverse gear’, например, is responsible for moving the reverse idler gear into its mesh position.

The “прокладки” или “зубцы” of these forks are the primary wear item. They are in constant contact with the spinning synchronizer sleeve. Over millions of shifts, эти колодки могут изнашиваться. Worn shift forks are a primary cause of a “небрежный” оборотень, grinding gears, or the transmission “выскакивает” of gear under load. These forks are the most critical moving parts of the Компоненты внутреннего контроля FAW.

The “Логика”: Interlock System (1702081-A9p)

The most important “логика” принадлежащий Компоненты внутреннего контроля FAW is the **interlock system**. It is a critical safety mechanism that makes it physically impossible to select two different gears at the same time (which would instantly lock and destroy the transmission).

Этот “logic gate” is created by a clever mechanical system of plates, balls, и булавки:

• ‘Interlock plate’ (1702081-A9p, 1702082-A9p, 1702083-A9p, 1702089-A9p)
• ‘Steel ball’ (Q967165) – 4 единицы
• ‘Bushing-interlock plate’ (1702084-A9p)

This is how it works: The shift shafts (rails) run parallel to each other. Between them are channels containing the ‘Steel balls’. When all shafts are in neutral, the balls can move freely. Однако, as soon as one shift shaft (НАПРИМЕР., the 1st/2nd gear shaft) is moved, its ‘Interlock plate’ pushes one of the ‘Steel balls’ *sideways* into a groove on the *other* shift shafts (НАПРИМЕР., the 3rd/4th shaft). Этот “rogue” мяч, now out of its channel, physically blocks the other shafts from moving.

This ensures that only one shift shaft, and therefore only one shift fork, can be moved out of its neutral position at any given time. Это просто, robust mechanical “логика” is a core feature of the Компоненты внутреннего контроля FAW. A worn ‘Interlock plate’ or a missing ‘Steel ball’ is a critical failure that could allow a double-gear engagement.

The “Фиксатор” Система (Self-Locking)

The “стопор” system provides the “feel” of the gear shift and prevents the transmission from vibrating out of gear. Эта часть Компоненты внутреннего контроля FAW is comprised of the ‘Cover-self-locking mechanism’ (1702227-A9p), its ‘Gasket’ (1702228-A9p), and the four ‘Self-locking spring’ (1702061AA4P) единицы.

Each shift shaft has three “стопор” в нем проточены канавки: один для нейтрального, one for the “вперед” механизм (НАПРИМЕР., 3р-д), and one for the “назад” механизм (НАПРИМЕР., 4й). The ‘Self-locking spring’ pushes a small steel ball or “поршень” (often part of the 1702061AA4P assembly) into this groove.

When the driver shifts, they must apply enough force to overcome this spring, causing the ball to “pop out” of the neutral groove and “pop into” the 3rd gear groove. Именно это создает “щелкнуть” или “думать” that confirms the gear is fully engaged. It also serves as a critical locking mechanism, as the spring’s force holds the shaft in place, preventing engine vibration from “ходьба” the fork and causing the transmission to pop out of gear. A weak or broken ‘Self-locking spring’ is the primary cause of a transmission that will not stay in gear. This detent system is a key “логика” принадлежащий Компоненты внутреннего контроля FAW.

Limiters and Electronic Switches

The Компоненты внутреннего контроля FAW also include physical “stops” and electronic “sensors.” The ‘Limit stop block-shift rail’ (1702092-A9p) and ‘Limit stop block-reverse gear’ (1702068-A9p) are the final “hard stops” that prevent the shift forks from over-traveling. They are secured with ‘Flat head dowel pin’ (1702097-A9p) единицы.

The most important electronic part is the ‘Stop light switch assembly’ (3729100-71А). This is the **reverse light switch**. It is a simple plunger-style switch. When the driver moves the ‘Fork-reverse gear’ (1702067-A9p), the shift shaft presses this plunger, which completes an electrical circuit, turning on the truck’s white reverse lights and sounding the backup alarm. This switch is a critical safety component of the Компоненты внутреннего контроля FAW.

Окончательно, the ‘Shaft-shift rocker arm’ (1702074-A9p) and its ‘Support’ (1702072-А9К) form the pivot that transfers the driver’s shift-lever motion to the main shift shafts. Весь Компоненты внутреннего контроля FAW assembly is a complex mechanical computer.
