EQ1090型汽车分动器设计 摘 要：越野车需要经常在坏路和无路情况下行驶，尤其是军用汽车的行驶条件更为恶劣。这就要求增加汽车驱动轮的数目，因此，越野车都采用多轴驱动。 分动器的功用就是将分动器输出的动力分配到各驱动桥，并且进一步增大扭矩。分动器也是一个齿轮传动系统，它单独固定在车架上，其输入轴与分动器的输出轴用万向传动装置连接，分动器的输出轴有若干根，分别经万向传动装置与各驱动桥相连。 本文主要说明了越野车分动器的设计计算过程,主要分为设计和工艺两大部分。设计部分较详细的叙述了分动器的设计过程，选择结构方案、主要参数、齿轮设计、轴设计、计算校核、其他结构部件的设计。工艺部分主要对典型零件的工艺过程进行了分析，确定了各类零件的材料，制定了工艺过程卡片。 关键词：越野车分动器；齿轮；轴；啮合套；壳体工艺 EQ1090-based design of automotive sub-actuator Abstract: The need for off-road vehicles often have no bad roads and traffic situations, especially military vehicles driving conditions even worse. This requires increasing the number of motor vehicle wheel, therefore, off-road vehicle use multi-axis drive. Sub-actuator function is the allocation of transmission power output to the drive axle, and further increase the torque. Actuator is also a sub-gear drive system, which separately fixed on the vehicle chassis, the transmission input shaft and output shaft gear connected with universal joints, sub-actuator output shaft of a number of roots, respectively, by the universal gear with the bridge driver. This article describes the sub-terrain vehicle actuator design calculations, design and technology is divided into two major parts. The design of some of the more detailed description of the sub-actuator design process, select the structure of the program, the main parameters, gear design, shaft design, calculation verification, the design of other structural components. Process some of the major components of typical processes are analyzed to determine the types of parts materials, developed a process card.
