Problems solved by technology

In the case of hybrid power, if the car wants to accelerate, the engine will transmit the torque to the motor after the engine accelerates. Since the two motors have different speeds, the existing speed difference will easily lose torque.
This will not only reduce the working efficiency of the engine and motor, but also cause the adverse consequences of slow acceleration of the car

Abstract

A hybrid power transmission comprises double planet rows, a first motor, a second motor and a third clutch. The double planet rows include a first planet row and a second planet row, the first planet row comprises an outer gear ring, a first sun gear and a first planet gear, and the second planet row comprises a second outer gear ring, a second sun gear and a second planet gear; the first motor and the second motor are mounted on one side of the double planet rows, the first motor is connected with the first sun gear, and the second motor is connected with the second sun gear; the first planet gear and the second planet gear are meshed with each other and share a planet carrier; and one side of the third clutch is connected with the first sun gear, and the other side of the third clutch is connected with the second sun gear. The invention further provides a hybrid power transmission system comprising the hybrid power transmission. According to the technical scheme, energy loss is reduced, work efficiency of an engine and the motors is improved, and an automobile can be accelerated effectively.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a hybrid power transmission device and a hybrid power transmission system. Background technique [0002] As a new type of energy-saving and environment-friendly vehicle, the technology and market of the hybrid vehicle are in a stage of vigorous development. Compared with conventional vehicles and pure electric vehicles, the biggest difference between hybrid vehicles is the power system. [0003] A current hybrid vehicle generally has an engine and two motors. In the working state where the engine and the two motors are powered together, usually one of the two motors plays the role of power generation, and the other plays the role of driving, and there is a big difference in the speed of the two motors. In the case of hybrid power, if the car wants to accelerate, after the engine accelerates, the torque will be transmitted to the motor. Because the speeds of the...
