Abstract

The invention relates to the technical field of mechanical power transmission, in particular to a driving device used for a hybrid car. The driving device comprises a motor input end, a first motor, a second motor, a single-row planetary system and a double-row Ravigneaux planetary system. The motor input end is connected with a first inner gear of the single-row planetary system, a rotor of the first motor is connected with a sun gear of the single-row planetary system, and a planetary frame of the single-row planetary system transmits power to a big sun gear and a small sun gear of the Ravigneaux planetary system. A rotor of the second motor is connected with a public planetary frame of the Ravigneaux planetary system, and power is transmitted by a second inner gear of the Ravigneaux planetary system. The motor achieves gear reversing. The driving device improves motor working efficiency of the motor, achieves serial connection, parallel connection, mixed connection, recovering of brake energy and the like, achieves the aim of reducing discharge and prolongs actual service life of a pure electric vehicle through a serial connection mode.

Description

technical field [0001] The invention relates to the technical field of mechanical power transmission, in particular to a driving device for a hybrid electric vehicle. Background technique [0002] The world today is facing the problems of energy shortage and massive environmental degradation. As the awareness of environmental protection continues to rise and the price of oil rises more than it falls, traditional cars are increasingly troubled by the shortage of oil resources. Under the general situation that consumers are pursuing high cost performance, hybrid vehicles with two different power sources, low fuel consumption and low emissions have been developed in recent years, and a trend has formed. Energy conservation and environmental protection have gradually become the theme of the development of the automobile industry. Hybrid electric vehicles that combine the advantages of pure electric vehicles and fuel vehicles can better meet the comprehensive requirements of low ...
