2、,通過換擋可以使發(fā)動(dòng)機(jī)工作在其最佳的動(dòng)力性能狀態(tài)下。變速器的發(fā)展趨勢(shì)是越來越復(fù)雜,自動(dòng)化程度也越來越高,自動(dòng)變速器將是未來的主流。變速器可以在汽車行駛過程中,在發(fā)動(dòng)機(jī)和車輪之間產(chǎn)生不同的變速比,通過換擋可以使發(fā)動(dòng)機(jī)工作在其最佳的動(dòng)力性能狀態(tài)下。關(guān)鍵詞:變速器;結(jié)構(gòu);組成;原理ABSTRACTTransmission,usedtochangethetorqueandspeedoftheenginecrankshaft,inordertoadapttothecaratthestart,acceleration,roadtrafficandt
