Abstract

The invention discloses a clutch-transmission built-in type dual-motor hybrid power system which comprises an engine, an elastic damper, a first motor, a second motor, a clutch, a transmission, a clutch brake, a first brake, a second brake, a third brake and a fourth brake. The engine, the elastic damper, the clutch brake, the first motor, the clutch, the second motor and the transmission are sequentially mounted coaxially. The clutch is mounted in an inner cavity of the first motor; the transmission is mounted in an inner cavity of the second motor; and the clutch brake is connected with the clutch and used for controlling engaging and disengaging of the clutch. The first brake, the second brake, the third brake and the fourth brake are all connected with the transmission and used for controlling the working state of the transmission. The clutch-transmission built-in type dual-motor hybrid power system is small in size, low in weight, high in power density, high in reliability and abundant in driving mode, and has a better oil-saving and electricity-saving effect, low cost and high economic benefits.

Description

technical field

[0001] The invention relates to the field of vehicle power, in particular to a clutch-transmission built-in dual-motor hybrid power system. Background technique

[0002] Vehicle emissions and energy consumption have become a worldwide problem, and hybrid vehicles with low emissions and low energy consumption have become one of the mainstreams in the development of the current automotive industry. With the continuous advancement of urbanization and the rapid development of logistics and freight transportation, medium and heavy vehicles such as passenger cars and trucks that use diesel engines as internal combustion engines have been difficult to meet the requirements of cleanliness and comfort of modern commercial vehicles in terms of fuel efficiency, emissions, vibration and noise, etc. Therefore, a new generation of powertrain is urgently needed to solve the above problems. However, the existing plug-in hybrid electric vehicle industry has technical problem...
