自動變速箱是相對于手動變速箱而出現的一種能夠自動根據引擎轉速來換擋的設備。下面濟南自動變速箱維修廠家來講講自動變速箱和手自一體變速箱的區別。

Automatic transmission is a kind of equipment that can automatically shift according to engine speed, which is relative to manual transmission. Next, Jinan automatic transmission maintenance manufacturer will talk about the difference between automatic transmission and manual automatic transmission.

自動變速箱(AT)就是通過自動切換不同的行星齒輪，這樣來改變輸出比。這種變速器操作簡單、省勸但是缺點也非常明顯它油耗大，切維修不便。

Automatic transmission (AT) changes the output ratio by automatically switching different planetary gears. This transmission is simple and economical to operate, but its disadvantages are also very obvious. It consumes a lot of fuel and is inconvenient to cut and maintain.

自一體是在干式離合器和齒輪變速器基礎上加裝微機控制的自動變速系統。它能根據車速、油門、駕駛員命令等參數確定佳擋位，控制原來由駕駛員人工完成的離合器分離與接合、換擋手柄的摘擋與掛擋以及發動機的油開度的同步調節等操作過程，終實現換擋過程的操縱自動化。

Self integration is an automatic transmission system with microcomputer control based on dry clutch and gear transmission. It can determine the best gear according to the vehicle speed, accelerator, driver's command and other parameters, and control the original manual clutch separation and engagement, gear shifting and engagement of the shift handle, and the synchronous adjustment of the engine oil opening, so as to finally realize the automatic operation of the shift process.

1、實用功能不同。自體變速箱在手動模式可以讓駕駛者自主選擇換擋時機。而普通自動變速箱只能電腦選擇換擋時機，不能由駕駛者來選擇換擋時機。

1. The utility functions are different. In manual mode, the self transmission allows the driver to select the shifting time independently. The ordinary automatic transmission can only select the shift time by the computer, not by the driver.

2、結構不同。自-體變速器主要由普通的齒輪箱、電子控制離合器、自動換擋操縱機構和電子控制部分等組成。而普通自動變速箱是液力自動變速箱。

2. Different structures. The automatic transmission is mainly composed of an ordinary gearbox, an electronic control clutch, an automatic shift control mechanism and an electronic control part. The ordinary automatic transmission is a hydraulic automatic transmission.

3、模式不同。自一體有手動變模式和自動模式兩種可以選擇而自動變速箱是沒有手動模式的。

3. Different modes. The automatic transmission has two options: manual mode and automatic mode, while the automatic transmission has no manual mode.

實際上汽車的發動機并沒有那么脆弱，平時只要保持變速箱適宜的工作溫度,以吸定期換好機油、防凍液、速箱油,不會出太大問題。關注我們http://www.levangerpatrioten.com為您講解更多相關內容！

In fact, the engine of the car is not so fragile. Usually, as long as the gearbox is kept at a suitable working temperature, the engine oil, antifreeze and gearbox oil can be changed regularly. Follow us http://www.levangerpatrioten.com Tell you more about it!
