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 motor, a charging apparatus and a powertrain. The motor of the charging apparatus includes a rotor, a stator, a primary coil, and a secondary coil. The stator includes a stator core. The primary coil is wound around a yoke part of the stator core, and the primary coil is coupled to an external power supply. The secondary coil is wound around the yoke part of the stator core, and the secondary coil and the primary coil are wound around different groove structures inside the stator core. The primary coil and the secondary coil implement coupling voltage transformation through the stator core, to step up or step down an output voltage of the external power supply.

Abstract: An automotive propulsion system. Both a compressor and a first retarder in a first propulsion system are connected to a first motor, so that the compressor and the first retarder can share a same power source. This can reduce a weight and costs of the automobile and improve use efficiency of the motor to save energy. In the first propulsion system, a first disconnector is disposed to implement a connection or disconnection between the first motor and the first retarder, and a second disconnector is disposed to implement a connection or disconnection between the first motor and the compressor. This can implement independent operation of the first retarder and the compressor. In addition, when a first propulsion system does not provide power, the first disconnector is opened, to prevent the first motor in the first propulsion system from being reversely dragged. This reduces an energy loss.

Abstract: A hybrid power drive system is provided, including an engine, a gearbox, a drive motor, and a generator. The gearbox includes a first input end, a second input end, and a first output end. In an axial direction of the engine, the drive motor and the engine are located on a same side of the gearbox. An input shaft of the generator is in transmission connection with the output shaft of the engine. The engine and the drive motor are disposed on the same side of the gearbox, so that a dimension of the hybrid power drive system in the axial direction can be reduced, and the hybrid power drive system has a small volume and can be mounted in a narrow mounting position in a vehicle. The gearbox and the vehicle are further provided.

Abstract: A motor and a powertrain. The motor includes a stator, an end cover, and a housing. The housing may be configured to install the stator and the end cover, and the stator and the end cover are adjacently arranged along an axial direction of the motor. The end cover includes an outer circumferential surface, a side surface, and an internal channel. The outer circumferential surface includes at least one liquid inlet, and at least one liquid inlet is configured to receive coolant through the housing. The side surface faces the stator, and the side surface includes a plurality of liquid outlets. In the motor, the coolant can enter the end cover through at least one liquid inlet and be sprayed to the stator through the plurality of liquid outlets, to cool the stator.
