Mechanical and electric mixed electric controlling stepless variable speed driving system

Abstract

The invention comprises an internal combustion engine, a torsional vibration damper, two epicyclic trains, two motors, two driving shafts, a casing and a clutch. The internal combustion engine is connected with the planetary frame of the first epicyclic train through the torsional vibration damper and the first driving shaft the first motor is connected with the solar wheel of the first epicyclic train and the second motor is connected with the solar wheel of the second epicyclic train. The annular gear of the first epicyclic train is connected with the planetary frame of the second epicyclic train through the second driving shaft. The clutch drive disk is connected with the first driving shaft and the clutch driven disk is connected with the second driving shaft or the rotor of the first motor.

Description

technical field

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

[0002] According to the working mode of the vehicle drive system, hybrid vehicles are generally classified as series, parallel and hybrid. The hybrid system can transmit power in series and parallel at the same time. Generally, we believe that the hybrid system is better than the first two methods in improving the overall performance of the vehicle. The driving system designed by the present invention is exactly a kind of hybrid vehicle driving system.

[0003] In terms of vehicle speed change, a hybrid hybrid vehicle requires automatic speed change. In a hybrid hybrid vehicle, sometimes the internal combustion engine needs to be driven alone, sometimes the electric motor needs to be driven alone, and sometimes both need to be driven together...
