Patent number: 9809098Abstract: 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.Type: GrantFiled: December 16, 2015Date of Patent: November 7, 2017Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Chia Tsao, Jui-Tang Tseng, Kun-Ju Xie, Tsung-Han Wu

Publication number: 20170204941Abstract: 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.Type: ApplicationFiled: March 22, 2016Publication date: July 20, 2017Applicant: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Jui-Tang TSENG, Kun-Ju XIE, Chia TSAO, Tsung-Han WU
