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 first electricmotor generator, a first motor power shaft, and a second motor power shaft. The engine is selectively connected with at least one of the input shafts, and transmission between each input shaft and the corresponding output shaft is achieved through a gearshift gear pair; the first electric motor generator is provided with three idler gears, two of the idler gears are linked with two driving gearshift gears, one of the two driving gearshift gears is linked with the second motor power shaft, the several output shafts, the second motor power shaft and the rest one idler gear are linked with a differential mechanism respectively, the first motor power shaft is linked with the first electric motor generator, and a second electric motor generator can be used for stationary power generation by using power from the engine. 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...
