The invention relates to a variable-speed drive axle for an electric vehicle. The transaxle includes a first motor generator, a second motor generator, a first planetary gear train, a second planetary gear train, a ring gear shaft, and a housing. The first planetary gear train includes a first sun gear, a first carrier, and a first ring gear. The second planetary gear train includes a second sun gear, a second carrier, and a second ring gear. The first sun gear is coupled to the first motor generator, and the first ring gear is coupled to the ring gear shaft. A second sun gear is coupled to a second motor generator, and a second ring gear is coupled to the ring gear shaft. The first bracket and the second bracket are non-rotatable relative to the housing.
