Abstract: A powertrain system and an electric vehicle to reduce a structure size of the powertrain system. The powertrain system includes two subsystems. The two subsystems are disposed side by side in a first direction and are symmetrical to each other. Each of the subsystems includes a motor, a deceleration mechanism, and an output shaft. A rotation shaft of the motor is disposed in a second direction. The deceleration mechanism includes a cylindrical gear pair and a bevel gear pair. The cylindrical gear pair includes an active cylindrical gear and a driven cylindrical gear, and the active cylindrical gear is connected to the rotation shaft of the motor. The driven cylindrical gear is located on a side that is of the active cylindrical gear and that is away or distal from the other subsystem. The bevel gear pair includes an active bevel gear and a driven bevel gear.

Abstract: A power assembly and a vehicle. The power assembly includes a housing, and a first drive motor, a first speed reducer, a first oil path, a second drive motor, a second speed reducer, a second oil path, and a third oil path that are located inside the housing. The power assembly further includes a first oil pump and a second oil pump. The housing is provided with an oil pan. The first drive motor includes a first stator and a first rotor. The second drive motor includes a second stator and a second rotor. Both the first oil pump and the second oil pump are connected to the oil pan. The power assembly simplifies the oil paths in the housing and improve an integration level.

Abstract: An electric vehicle drive system and an electric vehicle are provided. The electric vehicle drive system includes a first powertrain, a second powertrain, a first transmission system, a second transmission system, and a battery system. The first powertrain is connected to the first transmission system. The second powertrain is connected to the second transmission system. The first powertrain includes a generator and an engine, and the engine drives the generator to generate electric energy. The generator drives the first-side wheels by using the first transmission system. The second powertrain drives second-side wheels by using the second transmission system. The battery system is connected to the generator and the second powertrain, and is configured to receive the electric energy output by the generator, and output stored electric energy to at least one of the second powertrain or the generator.
