The present invention relates to a two-speed transmission for an electric vehicle, which comprises: an input unit providing power; first and second transmission delivery units individually engaged with both sides of the input unit; first and second transmission gear units individually connected to the first and second transmission delivery units, and transmitting power through combination of gears with axes crossing each other; first and second braking units individually connected to the first and second transmission gear units to provide a braking force; and an output unit connected to the first and second transmission gear units to discharge power. Therefore, manufacturing costs are reduced, and a transmission ratio can be freely designed.

    본 발명은 전기자동차용 2단 변속장치에 관한 것으로, 동력을 제공하는 입력부와, 입력부의 양측에 각각 맞물리는 제1,제2변속전달부와, 제1,제2변속전달부와 각각 연결되고 축이 교차하는 기어의 조합으로 동력을 전달하는 제1,제2변속기어부와, 제1,제2변속기어부와 각각 연결되어 제동력을 제공하는 제1,제2제동부와, 제1,제2변속기어부와 연결되어 동력을 토출하는 출력부를 포함하여, 제조비용을 절감하며 변속비를 자유롭게 설계할 수 있다.
