Abstract: A transmission and a vehicle. A first clutch of the transmission is a bidirectional clutch. When the first clutch is disposed on an input shaft, the first clutch is located between a first-stage input gear and a second-stage input gear. When the first clutch is disposed on a countershaft, the first clutch is located between a first-stage output gear and a second-stage output gear. Alternatively, the transmission includes the first clutch and a second clutch that are disposed on the input shaft or the countershaft. A quantity of components in the transmission is reduced, and a structure of the transmission is simplified, to reduce costs of the transmission, and reduce production costs of the vehicle to some extent.

Abstract: Embodiments of this application provide a motor rotor, a motor, and a vehicle. A conductive pillar passes through an inner ring of a conductive bearing, an outer wall of the conductive pillar interference fits with the inner ring of the conductive bearing, and an end of the conductive pillar is grounded. In this way, it is ensured that a shaft current on a rotor body is discharged by using the conductive bearing and the conductive pillar, to prevent a main bearing of the motor rotor from being electrically corroded by the shaft current. In addition, the conductive bearing is sleeved on the grounded conductive pillar, so that the inner ring of the conductive bearing can interference fit with the outer wall of the conductive pillar.

Abstract: This application describes a motor that includes a housing, an output shaft, a conductive bearing, and a conductive component. The output shaft is disposed in the housing. A positioning hole is disposed on an end face of a first end of the output shaft, and the positioning hole is disposed coaxially with the output shaft. The conductive bearing is disposed in the positioning hole, and includes an inner ring, and an outer ring that is fixedly connected to the output shaft. One end of the conductive component is fixedly connected to the inner ring of the conductive bearing, and the other end is connected to the housing. In this application, the motor can output, by using the conductive bearing and the conductive component, charges accumulated in the output shaft, to eliminate a generated common-mode voltage.
