Abstract

The invention discloses a power driving system and vehicle. The power driving system comprises an engine, a plurality of input shafts, a plurality of output shafts, a reverse shaft, a reverse output gear and a first motor generator, wherein the engine is arranged to be selectively engaged with the input shafts; each input shaft is provided with a retaining position driving gear; each output shaftis provided with a retaining position driven gear; an upper hollow sleeve of the reverse shaft is provided with a first gear and a second gear of the reverse shaft, wherein the first gear and the second gear can be engaged with the upper hollow sleeveof the reverse shaft, the first gear of the reverse shaft meshes with one retaining position driving gear, and the second gear of the reverse shaft meshes with one retaining position driven gear; the reverse output gear is linked with the reverse shaft, and a reverse output gearupper hollow sleeve is arranged on one of the output shafts and can beengaged with one of the output shafts; and the first motor generator is arranged to be linked with the reverse output gear. In this way, when the vehicle is in a pure electric mode, the transmissionefficiency is high, and control logic of the vehicle is simple.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a power drive system and a vehicle. 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 related art known to the inventor, the transmission in a hybrid vehicle generally has a complex structure, few transmission modes, and in the pure electric mode, the transmission efficiency is on the low side. 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, and the pure electric mode transmission efficiency...
