Abstract
The invention discloses a transfer case, which relates to the technical field of vehicle engineering and comprises a case body, a double-output-shaft reducing mechanism, a steering driving mechanism, two planetary gear mechanisms and two output transmission mechanisms, gear rings in the planetary gear mechanisms are fixedly connected with the corresponding output shafts; a third gear is fixedly arranged on a sun gear shaft in each planetary gear mechanism, and the two third gears are meshed with each other; each output transmission mechanism comprises a door bridge input shaft coaxially and fixedly connected with a planet carrier in the corresponding planet gear mechanism and a door bridge output shaft in transmission connection with the door bridge input shaft, one door bridge output shaft is used for driving wheels on one side of the vehicle to rotate, and the other door bridge output shaft is used for driving wheels on the other side of the vehicle to rotate. The steering driving mechanism is used for driving a sun wheel shaft to rotate. Zero steering of the vehicle and steering in the running process can be achieved.
