Problems solved by technology
However, it has the following deficiencies: 1) the engine cannot directly drive the vehicle, especially at high speeds, so the energy efficiency is low; 3) There is only one power split ratio, so it is difficult to ensure good performance in a wide range of vehicle speeds in the hybrid driving mode; 4) In the pure electric driving mode, only the second motor decelerates Propelling the vehicle, which is less efficient when the top speed in this mode is increased

The present invention provides a hybrid electric drive device, comprising an engine, a first motor, a second motor, a first planetary row, a second planetary row, a first engaging and disengaging element and a second engaging and disengaging element; the first planetary row includes a first planetary row a sun gear, a first planet carrier and a first ring gear; the second planet row includes a second sun gear, a second planet carrier and a second ring gear; the engine is connected to the first planet carrier, and the first motor is connected to the first sun gear , the first planet carrier is connected with the second sun gear, the first ring gear is connected with the second ring gear through the first engagement and disengagement element, the first ring gear is connected with the second planet carrier through the second engagement and disengagement element, and the two An engagement and disengagement element switches the connection mode of the two planetary rows to realize more working modes, thereby improving the performance of the hybrid electric drive.
Description
[technical field] [0001] The invention relates to the technical field of vehicle drive, in particular to a hybrid electric drive device. [Background technique] [0002] The existing power-split hybrid electric drive device based on the planetary row uses the planetary row to decompose the power of the engine into two paths, one path of power flow drives the first motor to generate electricity, and the other path of power flow merges with the power output of the second motor to drive the vehicle . However, it has the following deficiencies: 1) the engine cannot directly drive the vehicle, especially at high speeds, so the energy efficiency is low; 3) There is only one power split ratio, so it is difficult to ensure good performance in a wide range of vehicle speeds in the hybrid driving mode; 4) In the pure electric driving mode, only the second motor decelerates Driving the vehicle is less efficient when the top speed in this mode is increased. Therefore, it is also expec...
