Abstract: A powertrain includes a motor, a reducer, and an elastic component. The reducer includes an input shaft, the motor includes an output shaft, the input shaft is coaxially coupled to the output shaft, a coupling end of the input shaft includes a first limiting platform and a first coupling surface, and a coupling end of the output shaft includes a second limiting platform and a second coupling surface. The first limiting platform and the second limiting platform are disposed opposite to each other along an axial direction of the input shaft. The elastic component is fastened between the first limiting platform and the second limiting platform. The elastic component allows the motor to move axially in an operation process. Compared with a manner in which inner and outer rings of a bearing of a fixed motor are completely fastened, this reduces an assembly requirement of the motor.

Abstract: This application describes examples of a differential device, a powertrain, and a vehicle. In one example, the differential device includes a housing, three planetary gears, two side gears, and at least one window. Each of the three planetary gears is mounted on an inner wall of the housing through a pin shaft, the three planetary gears are disposed spaced from each other along a circumferential direction of the housing. The two side gears are disposed on two sides of the three planetary gears along the axial direction of the housing and meshed with the three planetary gears. The main reduction gear drives the housing to rotate around the axial direction of the housing, so that the three planetary gears drive the two side gears to drive two drive shafts respectively.
