Title:
POWER TRAIN AND VEHICLE HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2018/077269
Kind Code:
A1
Abstract:
Disclosed are a power train and a vehicle having same. The power train (1000) 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 (4021a), a second switching portion (4021b) 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) selectively engages with one of the first switching portion (4021a) and the second switching portion (4021b). The first switching portion (4021a) and the second switching portion (4021b) are both in cooperative transmission with the output portion (4022). The input portion (4020) engages with the second switching portion (4021b), such that the rotation speed output by the input portion (4020) is reduced 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.
