Description
technical field [0001] The invention relates to the technical field of automobile power transmission systems, in particular to a dual-clutch transmission, a fuel power system and a hybrid power system. Background technique [0002] At present, in response to the new round of decline in emissions and fuel consumption, the national dual-point policy indicators have been tightened year by year, and traditional fuel vehicles have been unable to directly meet and respond to the new round of fuel consumption and the national dual-point policy requirements. In addition to continuing to increase R&D investment and improving engine thermal efficiency, domestic and foreign OEMs have proposed multi-speed, electrification, and integration solutions for transmissions. The multi-speed transmissions on traditional fuel vehicles have large axial dimensions, complicated shift control, and require major changes in technical solutions before they can be applied to hybrid vehicles. platformiza...
