Дополнительный блок левый верхний центральный вал: Деконструкция 4 Важные детали для безупречного вспомогательного привода

Welcome to this specialized technical analysis of the Дополнительный блок левый верхний центральный вал, a critical component within the CA10TA160M 10-speed transmission. This component is essential for the FAW Jiefang CA3250P66K2L1T1E 6×4 самосвал. Это руководство деконструирует 4 components that form the complete Дополнительный блок левый верхний центральный вал assembly for professional service.

The Дополнительный блок левый верхний центральный вал is a high-torque countershaft, или “layshaft,” for the auxiliary (Hi/Lo range) section of the gearbox. Its logic is to receive power from the main box and transmit it to the final output gears, enabling the 10-speed “range split” function that is critical for a heavy-duty dump truck.

Основной 1: The “Вал & Приводная шестерня” Логика (Основная сборка)

This component is the literal foundation of the Дополнительный блок левый верхний центральный вал сборка. Это сингл, integrated part that provides the “водить машину” for the auxiliary gearbox.

1. Компонент: ‘Welded intermediate shaft assy – вспомогательный ящик’ (1701515-A7G)
Этот (Комп 4) является основным компонентом. The name ‘Welded intermediate shaft assy’ (焊接中间轴总成) tells us exactly what it is. Это Дополнительный блок левый верхний центральный вал сам, and it is a non-serviceable assembly, meaning the gear(с) are permanently welded to the shaft.

The Welded Logic is a design choice for extreme strength. Instead of using splines or keys that can shear under high torque, the manufacturer has welded the gear(с) directly to the shaft. This creates a single, solid piece of steel that can withstand the immense, low-speed torque multiplication of the dump truck’s range box.

The Логика промежуточного вала это его функция. Этот Дополнительный блок левый верхний центральный вал acts as the “countershaft” или “layshaft” for the auxiliary gearbox. It receives power from the ‘Sub-Box Drive Gear’ (which is connected to the mainshaft) и, по очереди, its gear(с) are in constant mesh with the Hi/Lo range gears on the final output shaft.

Этот Дополнительный блок левый верхний центральный вал is one of several (НАПРИМЕР., Left Upper, Правый верхний) that form a robust, power-splitting design. Этот “multi-countershaft” layout is the key to the CA10TA160M’s high torque capacity, as it distributes the load across multiple gear contact points instead of just one.

Основной 2: The “Несущий & Поддерживать” Логика (Система крепления)

This group represents the complete bearing assembly that supports the Дополнительный блок левый верхний центральный вал. А “сварной” shaft like this requires a bearing system that can handle immense, multi-directional forces.

1. Компонент: ‘Tapered roller bearing outer ring’ (306/42-1-1) – Кол-во 2
Этот (Комп 1) это “cup” или “outer race” of the bearing. Two of these are used, one for the front bearing and one for the rear. This cup is precision-machined and is pressed *into the bore* of the auxiliary gearbox housing, where it remains stationary.

2. Компонент: ‘Tapered roller bearing inner ring’ (306/42-1-2) – Кол-во 2
Этот (Комп 2) это “cone” или “внутреннее кольцо” of the bearing, which includes the tapered rollers in their cage. This cone is pressed *onto the journals* (заканчивается) принадлежащий Дополнительный блок левый верхний центральный вал (Комп 4) and spins with it.

The Логика конического ролика is the most important concept for this Дополнительный блок левый верхний центральный вал. Unlike a simple ball bearing (which handles radial loads well) or a thrust washer (which handles axial loads well), a tapered roller bearing is specifically designed to handle *both* massive radial loads (а “толкая” force from the gear mesh) and massive *axial* loads (а “толкать” force generated by helical-cut gears) *at the same time*.

The Opposed Mounting Logic is how they work. The two tapered bearings (Комп 1 + Комп 2) are mounted in “opposition” at the front and rear of the Дополнительный блок левый верхний центральный вал. This creates an extremely rigid assembly that can support the shaft against thrust forces in *both* directions (fore and aft), ensuring perfect gear mesh alignment under all load conditions.

The Сервисная логика is why they are listed as separate inner and outer rings. They are a “подобранный набор” and must be replaced as one. A technician presses the outer rings into the housing and the inner rings onto the Дополнительный блок левый верхний центральный вал before final assembly.

Основной 3: The “Предварительная загрузка & Позиционирование” Логика (The Shim)

This final component is one of the most critical parts of the entire Дополнительный блок левый верхний центральный вал сборка. It is a single washer that ensures the longevity of the expensive bearings and shaft.

1. Компонент: ‘Positioning washer’ (1701518-A7G)
Этот (Комп 3) is the ‘Positioning washer’. In a tapered roller bearing application, this is not a simple washer; это “прокладка” или “gasket-shim.” Its thickness is precisely controlled, and its function is to set the “bearing pre-load.”

The Pre-load Logic is a high-precision assembly task. Tapered roller bearings cannot be “свободный” (with end play), nor can they be “too tight.” They require a specific, slight amount of “squeeze” или “предварительная загрузка” to function correctly.

During assembly of the Дополнительный блок левый верхний центральный вал, a technician installs the components and measures the “end play” (the in-and-out movement) with a dial indicator. They then select a ‘Positioning washer’ (Комп 3) of the *exact* thickness required to eliminate that end play and add the correct, specified pre-load (НАПРИМЕР., 0.05мм).

This washer is often placed between a bearing’s outer ring (Комп 1) and the housing or bearing cover. Its thickness is the only thing that guarantees the correct pre-load.

А Дополнительный блок левый верхний центральный вал with incorrect pre-load (НАПРИМЕР., a shim that is too thick or too thin) will suffer catastrophic bearing failure in a very short time. Too tight, and the bearings will overheat and seize. Too loose, and the shaft will “ходить” аксиально, causing the gear teeth to misalign and destroying both the shaft (Комп 4) and the gears it meshes with. Поэтому, this ‘Positioning washer’ (Комп 3) является критическим компонентом.
