The invention discloses a multi-drive differential mechanism. The external power drives a driving bevel gear through an input shaft, the driving bevel gear directly drives a main ring gear so as to drive two differential unit shells, and a half shaft connected with a half shaft bevel gear can rotate along with the rotation of a differential mechanism shell; the rotation of the half shaft directlydrives a corresponding half-shaft transmission gear, and then a driven gear directly meshed with a half shaft gear is driven; under the transmission of idle gears meshed with each other, the rest driven gears are driven; due to the fact that synchronizer lock rings are fixedly installed on the corresponding driven gears, the external power can be transmitted to any synchronizer lock ring through aseries of gear transmission; further, a synchronizer is shifted to be combined with different positions, so that spline hubs of the synchronizer are connected with the selected synchronizer lock rings, and the power can be output through a selected output shaft; and more driving modes are provided for the movement of a vehicle, the cross-country driving performance of the vehicle is improved, andthe vehicle has better passing performance.
