Electric continuous speed regulation system of hybrid power automobile

Abstract

The invention relates to a hybrid automobile electronic stepless speed regulating system which comprises an engine, a clutch, a double-stator permanent magnetic brushless motor, an electric power module, a storage battery power module, a driving motor, a main reducer, driving wheels and a central control unit. The hybrid automobile electronic stepless speed regulating system has good fuel economy, low tail gas exhaust, multiple operation modes and good adaptability. The double-stator permanent magnetic brushless motor is used as a power distribution device, thereby effectively solving the disadvantages of the mechanical structure of the original planetary gear transmission, such as transmission loss, gear noise and the like. The hybrid automobile electronic stepless speed regulating system has simple structure and adopts electric connection, thereby being capable of arranging the structure of the whole automobile reasonably, using the space efficiently and improving the riding comfortableness. The hybrid automobile electronic stepless speed regulating system uses the central control unit to help to regulate the power of the whole system, so not only the power provided by the engine can be used completely, but the engine also can always run at a high efficient area under various of cruise modes of the automobile, and the efficiency of the whole automobile is improved effectively.

Description

technical field [0001] The invention belongs to the technical field of automobile power, and relates to an electronic stepless speed regulation system of a hybrid electric automobile. Background technique [0002] In recent years, the price of crude oil has been rising continuously. Along with the rapid growth of the national economy, the number of automobiles in our country is increasing at the fastest speed in the world. Under the situation that the number of such automobiles increases sharply, hybrid electric vehicles have received widespread attention due to their advantages of high fuel efficiency and low exhaust emissions. At present, the electronic stepless speed regulation system of the advanced hybrid electric vehicle mostly adopts the electronic stepless transmission, and its core device is a planetary gear structure. The planetary gear structure better solves the problems of engine power distribution and drive torque synthesis. However, like all mechanical gears...
