Shift schedule and actualizing techniques of tractors automatic mechanical transmission 换挡规律及实施技术研究
The gearshift strategy for parallel hybrid electric vehicle with automatic mechanical transmission 并联式混合动力汽车机械式自动变速器换档策略
Automatic mechanical transmission is advantaged due to its simple structure , low cost and high efficiency 电控机械式自动变速器以其结构简单、成本低、效率高,在自动变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 ) 当今车辆自动变速器分为三类,它们分别是:液力机械自动变速器( at ) 、机械无级自动变速器( cvt )以及电控机械式自动变速器( 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 制定的液力变矩器和机械自动变速器的综合换挡规律,既可满足低挡位越野性能和机动性能的要求,又可在良好路面、高挡位行驶时满足燃油经济性的要求。
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 在我国,手动变速器占主导地位,利用amt技术,以较少的资金便能完成手动变速器的自动化改造,大大减轻驾驶员的工作强度,非常适合中国国情。
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 电控机械式自动变速器( amt )是在传统固定轴式变速器和干式离合器的基础上,采用电子技术和自动变速理论,以电子控制单元为核心,通过液压执行系统控制离合器的分离与接合,选换档操作以及发动机节气门的调节来实现起步、换档的自动操纵。
