现代高级轿车皆广泛装用自动变速器。这种变速器的挡位通常是利用装置在方向盘下方的换挡手柄通过一套杠杆机构来拨动伞形齿轮轴,从而改变控制油道流通路径的活塞位置来进行变换。这样的操纵方法其缺点为:杠杆机构的零件繁多、加工和安装较困难;驾驶员的劳动强度较高;变换挡位的时间较长。为了减轻驾驶
Modern limousines are widely equipped with automatic transmission. The shift range of such a transmission is usually shifted by shifting the piston position of the oil passage in the oil passage by shifting the bevel gear shaft through a set of lever mechanisms by means of a shift lever provided below the steering wheel. Disadvantages of such a manipulation method are: many parts of the lever mechanism, processing and installation more difficult; driver’s labor intensity is higher; shift gear longer. In order to reduce driving
