Abstract

The invention discloses a power drive system used for a vehicle and the vehicle. The power drive system comprises an engine, a plurality of input shafts, a plurality of output shafts, a motor power shaft, a first electric motor generator, a second electric motor generator, a motor power shaft and a differential mechanism. The engine can be connected with the input shafts, the output shafts correspond to the input shafts, and the motor power shaft is sleeved with three gears; the first gear is linked with the several output shafts and the differential mechanism, and the second gear and the third gear are linked with two driving gearshift gears in a one-to-one correspondence mode; the first electric motor generator is linked with the motor power shaft, and the second electric motor generatorand the engine are located on the input side, at least one part of power of the engine can be used for stationary power generation. The power drive system is rich in drive mode, high in drive efficiency and high in stationary power generation efficiency.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a power drive system for a vehicle 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 is driven by an engine and / or an electric motor, and has multiple modes, which can improve transmission efficiency and fuel economy. [0003] However, in the relevant technologies known to the inventor, some hybrid electric vehicles have few drive modes, low drive transmission efficiency, and low power generation efficiency in the parking power generation working condition. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a power drive system for...
