Problems solved by technology

[0003] The dual-motor synchronous drive system has been widely used in new energy vehicles. Many domestic vehicle manufacturers and research units have conducted long-term research and obtained rich research results. The invention patent "a dual-power drive walking mechanism" CN200910092227. 2. Combining the two driving forces in the same driving mechanism, the main and auxiliary driving forces are synthesized and output through the differential gear train, driving the left and right wheels to achieve various driving states of the vehicle, but due to its long transmission chain and complex structure , failed to obtain practical production application; it is of practical value to explore and research a dual-motor synchronous drive system with high transmission efficiency, simple structure and stable operation

Abstract

The invention relates to a dual-motor synchronous driving device, which belongs to the technical field of mechanical transmission, in particular to the technical field of power synthesis driving, and comprises a first gear, a second gear, a third gear, a fourth gear, a transmission shaft, an elastic element, a first motor, a second motor and a transmission box body. The two motors are connected with two input gears, the input gears and a driving gear are in meshing transmission, the driving gear and an output shaft are connected through the elastic element, input rotating speed synchronization difference caused by motor rotating speed fluctuation in the transmission process is compensated by the elastic element, gear meshing motion interference is avoided, and dual-power synchronous driving and synthetic output are achieved. Meanwhile, dual-motor redundant driving is realized based on the dual-motor synchronous driving device.
