Abstract

The invention provides a hybrid electric vehicle power system which is larger in transmission ratio and can make an engine work in an efficient zone and make the working efficiency of a driving motor higher. A first planet row of first sun wheels (6) of the system is fixedly connected with a second planet row of second sun wheels (11), the left end of an outer ring (5) is fixedly connected with a first planet row of first gear rings (9), the right end of the outer ring (5) is fixedly connected with a second planet row of second gear rings (14), the outer side is fixedly connected with a motor rotor (41) of a driving motor (4), the left end of a connecting shaft (10) is connected with a clutch (3), the middle of the connecting shaft (10) is connected with a brake (6), the right end of the connecting shaft (10) is connected with a first planet row of first planet carriers (8), a rotor (171) of an ISG power generator (17) is fixedly connected with a crankshaft (2) of the engine (1) and is located between the engine (1) and the clutch (3), and the right ends of a second planet row of second planet carriers (13) are fixedly connected with an output shaft (15).

Description

technical field [0001] The invention relates to a hybrid electric vehicle, in particular to a hybrid electric vehicle power system. Background technique [0002] The power system of a hybrid electric vehicle can not only meet the requirements of energy saving and emission reduction, but also has a smooth shifting process without impact and high efficiency. At present, the common hybrid electric vehicle power system includes the engine, the drive motor and the first planetary row. Its shifting process is smooth and impactless, and its work efficiency is high. Small, the engine cannot always work in the high-efficiency area, and at the same time, the drive motor has low working efficiency, high temperature and heat generation, and high cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hybrid electric vehicle power system, which has a large transmission ratio, can make the engine always work in the high-effic...
