The invention discloses an efficient variable-speed hybrid vehicle drive system. The efficient variable-speed hybrid vehicle drive system comprises an internal combustion engine, a transmission gear pair, a generator, a motor, a vehicle-mounted storage battery, a separation clutch, a multi-gear variable speed gear pair, a first multi-stage gearbox and a second multi-stage gearbox, wherein the transmission gear pair comprises a first transmission driving gear and a first transmission driven gear which are meshed with each other, and the transmission ratio of the first transmission driving gearis smaller than 1; a first transmission shaft A of the internal combustion engine is fixedly connected with the first transmission driving gear, a rotating shaft of the generator is fixedly connectedwith the first transmission driven gear, the generator is electrically connected with the vehicle-mounted storage battery, the vehicle-mounted storage battery is electrically connected with the motor,the motor is in transmission connection with the second multi-stage gearbox, and the tail end of the first transmission shaft A of the internal combustion engine is in transmission connection with the separation clutch. According to the efficient variable-speed hybrid vehicle drive system, the structure is compact, and the problem of insufficient power performance and economy of the hybrid vehicle is solved.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a high-efficiency shifting hybrid vehicle drive system. Background technique [0002] At the beginning of the 21st century, countries all over the world called for improving environmental protection, and various electric vehicles came to the fore. Although it is generally believed that the future is dominated by electric vehicles, the current battery technical problems hinder the application of electric vehicles. Due to the Compared with the energy density of gasoline, the energy density of gasoline is hundreds of times worse, and it has not yet reached the value required by people. At present, hybrid electric vehicles emerge as the times require, and are favored by the market. The so-called hybrid electric vehicles combine an electric motor and an auxiliary power unit as a driving force on a vehicle. The auxiliary power unit is actually a small fuel engine or a power unit. ...
