    Abstract: A parking brake includes transmission shaft, park gear and parking assembly. The park gear is connected to the transmission shaft. The parking assembly includes holder and engagement mechanisms. The holder on the transmission shaft is slidable in axial direction of the transmission shaft. The engagement mechanism includes engagement body and elastic member. The engagement body is furnished on the holder and slidable in a radial direction of the transmission shaft. The elastic members are connected to the holder and located between the holder and the engagement bodies. The engagement bodies protrude from a surface of the holder. When the parking assembly is moved toward the park gear, and some of the engagement bodies are pressed and moved with respect to the holder, the park gear is engaged with some of the plurality of engagement mechanisms not moved with respect to the holder.

    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.

    Abstract: A dual-shaft clutch varying speed device includes a drive unit, an input shaft, an output shaft, a housing, at least an odd-numbered clutch unit and at least an even-numbered clutch unit. The input shaft having an input gear is coupled with the drive unit. The output shaft, having an end thereof penetrate through the input shaft and the drive unit, has at least an odd-numbered output gear and at least an even-numbered output gear. The housing has a housing gear. The at least one odd-numbered clutch unit being furnished at the inner part of the housing has an odd-numbered clutch shaft and an odd-numbered clutch gear which is meshed with the odd-numbered output gear. The at least one odd-numbered clutch unit has an even-numbered clutch shaft and an even-numbered clutch gear which is meshed with the even-numbered output gear.

    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.
