Abstract: A two-speed transmission for an electric vehicle including an electric motor, a first transmission mechanism and a second transmission mechanism is provided. The electric motor includes a rotor and a spindle. The rotor drives a first sun gear and a first planet gear of the first transmission mechanism to rotate with respect to the first ring gear to generate a first gear ratio. The rotor drives a second sun gear and a second planet gear of the second transmission mechanism to rotate with respect to the second ring gear to generate a second gear ratio different from the first gear ratio. When the first clutch connects with the spindle, the second clutch separates from the spindle, and a first torque is outputted to the spindle. When the second clutch connects with the spindle, the first clutch separates from the spindle, and a second torque is outputted to the spindle.

Abstract: A two-speed transmission having two clutches for an electric vehicle includes an electric motor, a middle shaft, a first clutch, a second clutch, a first gear assembly and a second gear assembly. The electric motor includes a spindle. The first and second clutches are furnished on the middle shaft coaxially. The first gear assembly is furnished on the spindle and the first clutch respectively to generate a first gear ratio. The second gear assembly is furnished on the spindle and the first clutch respectively to generate a second gear ratio different from the first gear ratio. When the first clutch is activated to connect with the middle shaft, the second clutch separates from the middle shaft, and the electric motor outputs a first torque corresponding to the first gear ratio to the middle shaft. Similarly, the electric motor outputs a second torque corresponding to the second gear ratio.

Abstract: A two-speed transmission having two clutches includes an electric motor, a middle shaft, a first clutch, a second clutch, a first gear assembly and a second gear assembly. The electric motor includes a spindle. The first clutch and the second clutch are furnished on the middle shaft coaxially. The first gear assembly and the second gear assembly are coupled to the first clutch and the second clutch through a first shaft portion and a second shaft portion of the middle shaft to generate a first gear ratio and a second gear ratio, respectively. When the first clutch is activated to connect with the first shaft portion, the second clutch separates from the second shaft portion, so that the electric motor outputs a first torque corresponding to the first gear ratio through the first gear assembly. Similarly, the electric motor outputs a second torque corresponding to the second gear ratio.
