The invention discloses a multi-gear dual-motor hybrid electric vehicle and a transmission system thereof, the transmission system comprises a planetary gear structure, a first variable speed transmission structure, a second variable speed transmission structure and a final power output mechanism, the input end of the planetary gear structure is selectively in transmission connection or disconnection with an engine and a second motor; the first variable transmission structure comprises a first-gear transmission structure and a second-gear transmission structure which are independent from each other, and the output end of the planetary gear structure is selectively in transmission connection or disconnection with the first-gear transmission structure and the second-gear transmission structure; the input end of the second variable-speed transmission structure is connected with the first motor, and the output end of the second variable-speed transmission structure is in transmission connection with one of the second-gear transmission structure and the first-gear transmission structure; and the input end of the final power output mechanism is in transmission connection with the first-gear transmission structure and the second-gear transmission structure at the same time. By means of the transmission system, the problems that when a full dead axle gear structure runs and shifts gears, a pause feeling exists, and a two-gear ECVT power dividing mode is difficult to achieve are solved.
Description
technical field [0001] The invention relates to the field of hybrid electric vehicles, in particular to a multi-speed dual-motor hybrid electric vehicle and its transmission system. Background technique [0002] The hybrid drive system is a hybrid drive system with pure electric drive, pure engine drive and hybrid drive capabilities, mainly through the structure of the transmission to achieve the switching between various power. How to couple the power of the engine and the motor, and how to coordinate the coupling output of the power source, so that the power and economy are good, are the difficulties of related technologies. [0003] Existing hybrid passenger car drive systems mainly include series hybrid drive systems, parallel hybrid drive systems, and hybrid hybrid drive systems. The series hybrid drive system is mainly composed of engine, generator ( / starter), motor ( / generator), power electronic equipment, power battery and manager; the principle of the transmission ...
