The invention belongs to the technical field of hybrid electric vehicles, and discloses a transmission for a two-gear hybrid electric vehicle. Comprising an engine (1), a generator (9), an input shaft (3) and an output shaft (11), a generator speed reduction assembly is fixedly connected with the generator (9), a second gear transmission mechanism is fixedly connected with the output shaft (11), a first gear transmission mechanism is fixedly connected with the input shaft (3), and a synchronizer (13) is arranged on the input shaft (3). The synchronizer (13) is arranged to be of a structure capable of controlling combination and separation of the first driving gear (15) and the second driving gear (10), and the transmission ratio of the first gear transmission mechanism is larger than that of the second gear transmission mechanism. According to the transmission for the two-gear hybrid electric vehicle, the performance of the transmission can be effectively improved, and therefore the economical efficiency, endurance sustainability and gear shifting smoothness of the hybrid electric vehicle are improved.
