Power transmission system of automobile and automobile

Abstract

The invention discloses a power transmission system of an automobile and the automobile, which belongs to the technical field of vehicle engineering. The system comprises an engine, an engine brake, afirst electric machine, a second electric machine, a planetary gear train, a planetary gear clutch, a dual clutch system, a planetary gear train ring gear brake and a third gear box. A first transmission end of the planetary gear train is sequentially connected with an engine brake and an engine transmission through a transmission shaft, a second transmission end of the planetary gear train is respectively connected with a planetary ring gear brake and a first electric machine through a transmission shaft, and a third transmission end of the planetary gear train is drivingly connected with one end of a dual clutch system; A planetary gear clutch is disposed between the planetary gear train and the first electric machine; The other end of the dual clutch system is drivingly connected to the first transmission end of the third gear transmission, the second transmission end of the third gear transmission is drivingly connected to the second motor, and the third transmission end of the third gear transmission is drivingly connected to the wheels of the vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a power transmission system of an automobile and the automobile. Background technique [0002] With the development of science and technology, the number of cars is increasing. With the increase of the number of cars, energy consumption and environmental pollution are more and more concerned by people. In order to reduce energy consumption and reduce vehicle exhaust emissions, the application of hybrid vehicles came into being. A hybrid vehicle refers to a vehicle equipped with two or more power sources, such as batteries, fuel cells, internal combustion engines, motors, etc. Currently, hybrid vehicles generally refer to vehicles whose power sources are internal combustion engines and electric motors. [0003] At present, the structure of the power transmission system of hybrid electric vehicles is mainly developed based on the traditional custom gearbox. Specifical...
