Abstract

The invention discloses a power driving system and a vehicle. The power driving system comprises an engine, a first motor generator, a second motor generator and a transmission. According to the transmission, a first shaft is connected with the crankshaft of the engine; the first motor generator is in power coupling connection with the first shaft; a second shaft is selectively in power coupling connection with the first shaft through a first clutch; the second motor generator is connected with the second shaft; a first part and a second part are selectively jointed with a third part; the third part is arranged on the rotor of the second motor generator; a third shaft and a fourth shaft are each provided with a gear driving gear; the third shaft is connected with the first part; the fourthshaft is connected with the second part; and a fifth shaft is provided with gear driven gears correspondingly engaged with the gear driving gear. According to the power driving system, the adjustablerange of a transmission speed ratio is large; gear difference is small; the operation efficiency of a motor is improved; and no power interruption phenomenon exists during gear shifting.

Description

technical field [0001] The invention relates to the technical field of vehicle manufacturing, in particular to a power drive system and a vehicle with the power drive system. Background technique [0002] With the continuous consumption of energy, the development and utilization of new energy vehicles has gradually become a trend. As one of the new energy vehicles, a hybrid vehicle can be driven by an engine and / or an electric motor and can implement various working conditions to improve the fuel efficiency and fuel economy of the transmission. In the related art, the length of the transmission chain from the driving force of the motor to the differential is long, the transmission efficiency is low, and the problem of power interruption is prone to occur during the shifting process, so there is room for improvement. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] The power d...
