Problems solved by technology

At present, there are many different schemes for the transmission system of hybrid electric vehicles, and each scheme has its own advantages and disadvantages. Generally speaking, the integration degree of the existing schemes is low, the weight and layout of the transmission system require a large space, and there are few operating modes. It is difficult to adapt to complex working conditions, which is not conducive to improving the power and fuel economy of the vehicle

Abstract

The invention discloses a power coupler for a hybrid power automobile and an operation mode of the power coupler. The power coupler comprises an engine, a first planetary line, a second planetary line, a first motor, a second motor and a power battery. The first motor and the second motor are connected with the power battery, a first clutch and a first brake are arranged between the engine and thefirst planetary line, and a second brake is arranged between the first planetary line and the second motor. The first planetary line is connected with the second planetary line through an outer gearring driving wheel, and the second planetary line is connected with a differential mechanism through a gear set. The power coupler is compact in structure and high in integration degree, a plurality of working modes can be achieved through different control strategies, and thus the dynamic property and the economic property of the automobile can be improved.

Description

technical field [0001] The invention relates to the technical field of power transmission of a hybrid electric vehicle, in particular to a power coupler used in multiple working modes of a hybrid electric vehicle and its operation mode. [0002] technical background [0003] Under the pressure of energy and environment, new energy vehicles and other unconventional vehicles have achieved development and progress. Among many new energy vehicle research and development, hybrid vehicles have the most practical value. At present, there are many different schemes for the transmission system of hybrid electric vehicles, and each scheme has its own advantages and disadvantages. Generally speaking, the integration degree of the existing schemes is low, the weight and layout of the transmission system require a large space, and there are few operating modes. It is difficult to adapt to complex working conditions, which is not conducive to improving the power and fuel economy of the veh...
