Problems solved by technology

Although it can realize the drive of the two gears of the engine, but during the gear shifting process, when the synchronizer operates, the speed difference between the first gear and the second gear input gear is relatively large, which will cause a large impact and cause damage to the components. Some damage, and will affect ride comfort and fuel economy

Abstract

The invention discloses a hybrid power vehicle driving system capable of governing speed by using motors during gear shifting. The hybrid power vehicle driving system comprises an engine, a planetarygear mechanism, a synchronizer and the first motor, the planetary gear mechanism comprises a sun gear fixedly connected with a transmission shaft of the engine, an outer gear ring connected with a brake, a planet carrier connected with the outer gear ring through a clutch, and a planetary gear arranged on the planet carrier and meshed with the sun gear and the outer gear ring respectively, and thesynchronizer is fixedly connected to an intermediate shaft. The two sides of the synchronizer can be connected with a first gear and a second gear which are separately arranged on the intermediate shaft in an idling and sleeving mode, the outer gear ring and the planet carrier are coaxially and fixedly connected with a third gear and a fourth gear respectively, and the third gear and the fourth gear are meshed with the second gear and the first gear respectively. The intermediate shaft, a transmission shaft of the engine and a transmission shaft of the first motor are fixedly connected with afifth gear, a sixth gear and a seventh gear respectively, and the fifth gear and the sixth gear are meshed with a differential gear which is fixedly connected to the differential and a seventh gear respectively. The system simplifies a transmission system, the motor is used for speed regulation during gear shifting, and the gear shifting impact is reduced.

Description

technical field [0001] The invention belongs to the technical field of hybrid electric vehicle drive, and in particular relates to a hybrid electric vehicle drive system which utilizes a motor for speed regulation when shifting gears. Background technique [0002] Hybrid vehicle drive is the core stage of the development of new energy vehicles. In order to obtain more functions and higher efficiency, the current hybrid vehicle drive system adopts a relatively complicated structure and high cost. Prior art CN108725178A discloses a single planetary gear multi-mode hybrid transmission, which proposes that the outer ring gear of the planetary gear meshes with the third gear (second gear output gear), and the planetary carrier directly engages with the first gear (first gear input gear). connected. The output shaft of the engine is connected to the outer ring gear of the planetary gear train, and the clutch or brake is connected to the outer ring gear and the transmission housin...
