DISC POWERTRAIN WITH DUAL-DRIVE OR SINGLE-DRIVE DUAL-SPEED TRANSMISSION AND ELECTRIC VEHICLE

Abstract: a disc powertrain with dual-drive or single-drive dual-speed transmission and an electric vehicle. a disc powertrain with dual-drive dual-speed transmission includes a gearshift mechanism, two disc motors, and two planetary gear reducers. the gearshift mechanism is configured to: separate a transmission connection between a planet carrier of one planetary gear reducer and a half shaft of one wheel, separate a transmission connection between a sun gear of the one planetary gear reducer and a motor shaft of one disc motor, and restore a transmission connection between the motor shaft of the one disc motor and the half shaft of the one wheel. in the disc powertrain provided, the disc motor is able directly in transmission connection with the wheel without using the reducer, thereby reducing power loss in process of driving the wheel, and improving integration to facilitate miniaturization of the disc powertrain.
