Problems solved by technology

[0010] However, in the case of the current radial size of the planetary row, if it is necessary to change the characteristic parameter k of the planetary row to match different engines and first electric motors, it is necessary to increase the overall size of the planetary row, for example: increasing the characteristic parameter requires increasing the internal teeth The size of the outer diameter of the ring, reducing the characteristic parameters requires reducing the size of the planetary gear, but the size of the planetary gear cannot be reduced without limit due to the size of the planetary gear shaft and bearing, which will instead lead to an increase in the outer diameter of the inner ring gear
Existing hybrid vehicle drives and planetary arrays for hybrid vehicle drives do not provide better fuel economy or power at current planetary array radial dimensions

Abstract

The invention discloses a planet row of a hybrid power vehicle driving device and the hybrid power vehicle driving device. The hybrid power vehicle driving device comprises an engine, a first motor, asecond motor, an intermediate shaft, a differential gear and a planet row. An output shaft of the engine is connected with a planet carrier, an output shaft of the first motor is connected with a rotating shaft of a sun gear, and the output shaft of the engine, the planet carrier, the sun gear and the output shaft of the first motor are coaxially arranged. The first motor is connected with the second motor, and an output shaft of the second motor is connected with an input gear. A driving wheel and a driven wheel are arranged on the intermediate shaft, the driven wheel is meshed with outer teeth and the input gear at the same time, and the driving wheel is meshed with the differential gear. By using the device, the characteristic parameters of the planet row can be adjusted by adjusting the tooth number of a first planet wheel and the tooth number of a second planet wheel, then the kinematics and dynamics processes of the planet row are adjusted, and better fuel economy or power performance is achieved on the premise that the radial size of the planet row is not changed.

Description

technical field [0001] The invention relates to the technical field of vehicle driving devices, in particular to a planetary row of a hybrid vehicle driving device and the hybrid vehicle driving device. Background technique [0002] At present, in the field of hybrid vehicle drive devices, the main technical representatives are Toyota THS system and Honda i-MMD system. The former uses planetary row to realize power coupling and shunting, and then simultaneously realizes series and parallel hybrid modes. The latter uses a clutch device to realize Switching between series and parallel, most of the configurations of other manufacturers’ hybrid drives are based on these two types of technologies. At the same time, due to the technical protection and barriers of the planetary row, most of the current market adopts a configuration similar to Honda’s i-MMD system. With the development of technology and the upgrading of consumption, higher requirements are put forward for the fuel e...
