Abstract

The invention discloses a power driving system for a vehicle and the vehicle. The power driving system comprises an engine, multiple input shafts, multiple output shafts, a motor power shaft, a firstelectric generator and a second electric generator, the engine is connected with at least one of the multiple input shafts, and one input shaft is provided with a first gear; the motor power shaft issleeved with a motor power shaft first gear and a motor power shaft second gear, the motor power shaft first gear can be in linkage with the first gear in the same direction, the motor power shaft second gear is in linkage with the first gear, and the motor power shaft first gear and the multiple output shafts are in linkage with a differential mechanism; the first electric generator is in linkagewith the motor power shaft; the second electric generator and the engine are located at in the input side of a first clutch device, and the second electric generator can utilize part of power outputby the engine to conduct parking power generating when the vehicle parks. In this way, the power driving system is rich in driving mode, high in driving efficiency and high in parking power generatingefficiency.

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...
