The invention discloses a dual-motor coaxial speed reducer transmission assembly, relates to the technical field of dual-motor speed reducers of new energy vehicles, and aims to solve the technical problem that power input and power output cannot be coaxial at the same time during transmission of dual-motor speed reducers of pure electric vehicles in the prior art. In the dual-motor coaxial speed reducer transmission assembly, a first motor is connected with a first sun gear through a first motor shaft, the first sun gear is connected with a first planet carrier through a first planet gear and a first inner gear ring, and the first planet carrier is connected with a differential mechanism shell. A second motor is connected with a second sun gear through a second motor shaft, the second sun gear is connected with a second inner gear ring through a second planet gear and a second planet carrier, and the second inner gear ring is connected with the differential mechanism shell. The first inner gear ring is connected with the second planet carrier, the differential mechanism shell is connected with the first half axle gear and the second half axle gear through the differential mechanism straight shaft and the differential mechanism planet wheel, and meanwhile the first half axle gear and the second half axle gear are connected with the first half axle and the second half axle respectively.
