Shift schedule and actualizing techniques of tractors automatic mechanical transmission 換擋規(guī)律及實(shí)施技術(shù)研究
The gearshift strategy for parallel hybrid electric vehicle with automatic mechanical transmission 并聯(lián)式混合動力汽車機(jī)械式自動變速器換檔策略
Automatic mechanical transmission is advantaged due to its simple structure , low cost and high efficiency 電控機(jī)械式自動變速器以其結(jié)構(gòu)簡單、成本低、效率高,在自動變速器中占有重要地位。
Nowadays automatic gear shifting is divided into three sorts : automatic transmission ( at ) , continuously variable transmission ( cvt ) , and automatic mechanical transmission ( amt ) 當(dāng)今車輛自動變速器分為三類,它們分別是:液力機(jī)械自動變速器( at ) 、機(jī)械無級自動變速器( cvt )以及電控機(jī)械式自動變速器( amt ) 。
The overall shift schedule with tc + amt ( automatic mechanical transmission ) is worked out , which meets both the requirements of off - mad performance and maneuverability at low gears as well as fuel economy at high gears on better road 制定的液力變矩器和機(jī)械自動變速器的綜合換擋規(guī)律,既可滿足低擋位越野性能和機(jī)動性能的要求,又可在良好路面、高擋位行駛時(shí)滿足燃油經(jīng)濟(jì)性的要求。
Mechanical transmission ( mt ) vehicles are in the majority in china . these manual transmissions can be changed into automatic mechanical transmissions with low cost . so automatic mechanical transmissions adapt to the situation of china 在我國,手動變速器占主導(dǎo)地位,利用amt技術(shù),以較少的資金便能完成手動變速器的自動化改造,大大減輕駕駛員的工作強(qiáng)度,非常適合中國國情。
Automatic mechanical transmission as so called amt , accomplishes automatic gearshift based on manual fixed - shaft and dry clutch , which takes ecu as kernel , and then uses hydraulic system to control clutch , gearshift and manipulates throttle by adopting electronics technique and automatic gearshift theory 電控機(jī)械式自動變速器( amt )是在傳統(tǒng)固定軸式變速器和干式離合器的基礎(chǔ)上,采用電子技術(shù)和自動變速理論,以電子控制單元為核心,通過液壓執(zhí)行系統(tǒng)控制離合器的分離與接合,選換檔操作以及發(fā)動機(jī)節(jié)氣門的調(diào)節(jié)來實(shí)現(xiàn)起步、換檔的自動操縱。
