POWER TRAIN AND VEHICLE HAVING SAME

WIPO Patent Application WO/2018/077270

A1

Disclosed are a power train and a vehicle having same. The power train comprises: a power source (100); a first motor-generator unit (300); a system power output portion (401); and a mode switching device (402), the mode switching device (402) comprising: an input portion (4020), a first switching portion, a second switching portion and an output portion (4022). The output portion (4022) is connected to an input end of the system power output portion (401). The input portion (4020) is adapted to output the power from at least one of the power source (100) and the first motor-generator unit (300). The input portion (4020) is fixedly connected to the first switching portion. The output portion (4022) selectively engages with the first switching portion (4021a) or the second switching portion (4021b). The output portion (4022) engages with the second switching portion, such that after the rotation speed output by the input portion (4020) is reduced by successively passing through the first switching portion and the second switching portion before being output to the input end of the system power output portion (401). In this way, driving modes of a vehicle can be enriched, and the vehicle can be adapted to different road conditions.
