AMT變速箱構造與原理 更新時間: 2019-08-22

贵州快三今天的开奖结果查询结果 www.wmwhd.icu AMT是在傳統的手動齒輪式變速器基礎上改進而來的;它揉合了AT和MT兩者優點的機電液一體化自動變速器;AMT既具有普通自動變速器自動變速的優點,又保留了原手動變速器齒輪傳動的效率高、成本低、結構簡單、易制造的長處。它是在現手動變速器上進行改造的,保留了絕大部分原總成部件,只改變其中手動操作系統的換檔桿部分,生產繼承性好,改造的投入費用少,非常容易被生產廠家接受。


駕駛員通過加速踏板和操縱桿向電子控制單元(ECU)傳遞控制信號;電子控制單元采集發動機 轉速傳感器、車速傳感器等信號,時刻掌握著車輛的行駛狀態;電子控制單元(ECU)根據這些信號按存儲于其中的最佳程序,最佳換檔規律、離合器模糊控制規律、發動機供油自適應調節規律等,對發動機供油、離合器 的分離與結合、變速器換檔三者的動作與時序實現最佳匹配。從而獲得優良的燃油經濟性與動力性能以及平穩起步與迅速換檔的能力,以達到駕駛員所期望的結果。

不過AMT變速箱并非完美的,AMT變速箱最大的缺點就是換擋舒適型不佳,且在換擋過程中產生動力中斷,使得換擋過程中極速性能不好。

the driver through the accelerator pedal and joystick to the electronic control unit (ECU) control signal transmission; electronic control unit acquires engine speed sensor, the speed sensor signal, the time to master the running state of the vehicle; electronic control unit (ECU) based on the best program according to these signals stored therein, the optimal shift schedule, fuzzy control clutch law, engine adaptive regulator, action and timing on engine oil, separation and combination of clutch and gear shifting of the three to achieve the best match. So as to obtain excellent fuel economy and dynamic performance, as well as the ability of smooth start and rapid shift, so as to achieve the desired results.

but AMT gearbox is not perfect, the biggest disadvantage is that the AMT gearbox shift comfort poor, and in the shift process to generate power outages, making the shift process is not good performance.
