8440-2167 同步器 主要作用是实现换档同步

8440-2167是一款同步器，是挂档齿轮的组合机构，它的主要作用是实现换档同步。在旧式变速器的换档过程中，操作复杂且难以精确掌握，因此设计师创造出同步器。同步器有多种形式，包括常压式、惯性式和自行增力式等，目前广泛采用的是惯性式同步器。

8440-2167主要由接合套和同步锁环等组成，它的特点是依靠摩擦作用实现同步。当驾驶员换档时，同步器能够使将要啮合的齿轮达到一致的转速，从而顺利啮合。这大大简化了换档操作，尤其是从高档向低档的换档操作，同时避免了齿间冲击。

请注意，8440-2167在汽车构造中起到至关重要的作用，对于确保变速器的平稳运行和延长其使用寿命具有重要意义。如果同步器出现问题，可能会导致换档困难、齿轮冲击或变速器损坏等后果。因此，对同步器的定期检查和维护至关重要。

8440-2167 is a synchronizer, is a combination of gear mechanism, its main role is to achieve shift synchronization. During the shifting process of the old transmission, the operation was complicated and difficult to accurately master, so the designer created the synchronizer. There are many forms of synchronizer, including atmospheric type, inertia type and self-strengthening type, inertia type is widely used at present.

8440-2167 is mainly composed of a joint sleeve and a synchronous lock ring, etc., which is characterized by relying on friction to achieve synchronization. When the driver changes gear, the synchronizer can make the gears to be engaged reach a consistent speed, thus smoothly engaging. This greatly simplifies the shift operation, especially from high to low gear, while avoiding the impact between teeth.

Please note that the 8440-2167 plays a vital role in the construction of the car and is important for ensuring the smooth operation of the transmission and extending its service life. If there is a problem with the synchronizer, it can lead to consequences such as difficulty shifting gears, gear shock, or transmission damage. Therefore, regular inspection and maintenance of the synchronizer is essential.
