Claims

[Scope of utility model registration request]

An input shaft disposed coaxially with the rotating shaft of the electric motor and connected to enable power transmission; an output shaft coaxially and relatively rotatably connected to the input shaft; a ring gear integrally provided with the output shaft; and the input shaft. A planetary gear unit consisting of a sun gear rotatably provided on a shaft and a carrier that rotatably supports a planetary gear that is integrally provided on the D input shaft and meshes with the ring gear and sun gear, and is movable in the axial direction on the sun gear. a cone clutch that is spline-coupled to and selectively moved to a position where it engages with the fixed member and a position where it engages with the ring gear; and a cone clutch that is assembled to the sun gear so that the cone clutch engages with the fixed member. and a one-way clutch that receives a reaction force acting on the sun gear while the cone clutch is moving to engage the ring gear, and a control device that controls the position of the cone clutch according to the driving state of the vehicle. Transmission for electric vehicles.
