Dual-clutch transmission applied to hybrid electric vehicle and application method thereof

Abstract

The invention relates to a dual-clutch transmission applied to a hybrid electric vehicle, wherein an output shaft of a motor / generator is connected with a first driving gear and a second driving gear through a double clutch respectively; an engine shaft of an engine is connected with an engine driving gear through an engine clutch; a second driven gear is meshed with the second driving gear and the engine driving gear respectively and connected with a first driven gear and a main reduction driving gear respectively through a synchronizer; the first driven gear is meshed with the first driving gear; the main reduction driving gear is meshed with a main reduction driven gear; the main reduction driven gear is mounted on a differential mechanism; a first gear clutch starter and a second gear clutch starter are connected with the double clutch respectively; and an engine clutch starter is connected with an engine clutch. The invention further relates to an application method of the dual-clutch transmission. The dual-clutch transmission applied to the hybrid electric vehicle has the advantages of unique design, simple structure, environmental friendliness, high driving range, economical efficiency, and good dynamic property, and generates enormous social and economic benefits.

Description

technical field [0001] The invention relates to the technical field of vehicle transmission systems, in particular to the technical field of hybrid vehicle transmission systems, and specifically refers to a dual-clutch transmission applied to hybrid vehicles and a method for using the same. Background technique [0002] As a means of transportation, electric vehicles have the advantages of being friendly to the environment and low dependence on petroleum. However, the current pure electric vehicles have disadvantages such as high battery cost, low driving range, and inconvenient charging. Currently, electric vehicles generally use The single-speed deceleration structure leads to a relatively narrow high-efficiency zone of the motor, resulting in poor economy. [0003] Therefore, there is an urgent need for an automotive transmission that is environmentally friendly, has a high driving range, and is economical and dynamic. Contents of the invention [0004] The purpose of ...
