Hybrid drive system in type of multiple series connection stepless speed change

Abstract

A drive system with mixed power and stepless speed variation is composed of engine with crankshaft output, the first and the second motors and their high-voltage circuits and drive controller, clutch, drive shaft, differential speed reducer, the first and the second semi-shafts, energy accumulator, and the high-voltage circuit for the energy accumulator.

Description

technical field

[0001] The invention relates to a system in the technical field of automobiles, in particular to a continuously variable variable speed hybrid drive system. Background technique

[0002] At present, the structural types of hybrid electric vehicle power drive systems include series, parallel, and series-parallel hybrid. Advantage. According to the characteristics of the three system structures, series hybrid vehicles are more suitable for urban areas where vehicles start and stop frequently; parallel hybrid vehicles are more suitable for non-urban areas with relatively smooth roads; It integrates the advantages of series hybrid system and parallel hybrid system and overcomes their respective shortcomings, so it can be applied to all road conditions and has great performance advantages.

[0003] The current series-parallel hybrid hybrid system, such as the most representative THS (Toyota Hybrid System) hybrid system of Toyota Motor Corporation of Japan and it...
