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.

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。
