Abstract

The invention discloses a series-parallel type transmission system for an oil-electricity hybrid electric vehicle. The series-parallel type transmission system comprises a transmission execution unit and a transmission control unit. The transmission execution unit comprises a first motor, a second motor and a third motor. An output shaft of the first motor is connected with a planet carrier of a single-row planet gear mechanism through a first clutch. An output shaft of the second motor is connected with a gear ring of the single-row planet gear mechanism through a second clutch. An output shaft of the third motor is connected with a sun gear of the single-row planet gear mechanism through a third clutch. The gear ring of the single-row planet gear mechanism is further connected with input shafts of wheels. The transmission control unit comprises a controller, the control input end of the controller is connected with a combination switch, and the control output end of the controller is connected with the first motor, the second motor, the third motor, the first clutch, the second clutch and the third clutch. The series-parallel type transmission system is simple in structure, convenient to operate, visual in display and safe, economical and environment-friendly in use.

Description

technical field [0001] The invention relates to a transmission system of a hybrid oil-electric hybrid vehicle. Background technique [0002] A hybrid vehicle refers to a vehicle that carries different power sources and can use different power sources at the same time or separately according to the driving needs of the vehicle. At present, the most common type is a gasoline-electric hybrid vehicle, that is, an engine and an electric motor are used as power sources. Hybrid vehicles can be divided into series, parallel and hybrid according to the power system structure. Although gasoline-electric hybrid vehicles cannot achieve zero emissions, they are more environmentally friendly, energy-saving and economical than traditional internal combustion engine vehicles, and will have a good development trend at present and in the near future. At present, the price of gasoline-electric hybrid vehicles is relatively expensive, and the technical data is lacking, which makes it difficult...
