摘要： A continuously variable transmission includes a primary shaft, a secondary shaft, a primary pulley, a secondary pulley, a first power transmission member, a primary sprocket, a secondary sprocket, a second power transmission member, and a power transmission switch. The first power transmission member has a loop shape and is wrapped around the primary pulley and the secondary pulley. The primary sprocket is disposed on the primary shaft. The secondary sprocket is disposed on the secondary shaft. The second power transmission member has a loop shape and is wrapped around the primary sprocket and the secondary sprocket. The power transmission switch disables power transmission by the second power transmission member when the first power transmission member is in a normal condition and enables the power transmission by the second power transmission member when the first power transmission member is in an abnormal condition.

摘要： A power distribution apparatus for an electric vehicle includes a power distribution mechanism configured to distribute power output from an electric motor to front and rear wheels, and a controller configured to control the power distribution mechanism. The power distribution mechanism includes a first clutch configured to fix a power distribution ratio during straight traveling to a first distribution ratio at which first power distributed to the rear wheels and second power distributed to the front wheels are nearly same, and a second clutch configured to fix the power distribution ratio during straight traveling to a second distribution ratio at which the first power is larger than the second power. The controller is configured set the second clutch to an engaged state and sets the first clutch to a half-engaged state during regenerative braking.
