主减速器(或叫主传动)是装载机驱动桥的重要组成部分,主要由主动螺旋伞齿轮组件、主减速器壳体(也有的叫托架)组件、差速器组件和从动螺旋伞齿轮组件等零部件组成,其主要功能是降低传动系的转速、增大传动系的转矩并改变转矩的方向,把纵置发动机的转矩传递到横置的两根驱动桥的 The main reducer (or main drive) is an important part of the drive axle of the loader. It is mainly composed of the active helical bevel gear assembly, the main reducer housing (also called bracket) assembly, the differential assembly and the driven spiral umbrella Gear components and other components, its main function is to reduce the speed of the powertrain, increasing the torque of the powertrain and change the direction of the torque, the longitudinal engine torque is transmitted to the transverse two transaxle
