Embodiment Construction
[0020] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0021] Embodiment of a hybrid drive system
[0022] Such as figure 1 As shown, the hybrid drive system in this embodiment includes an engine 1, a first motor 11, a second motor 12, and a single-planetary powertrain, and the single-planetary powertrain includes a planetary carrier 6, a sun gear 13, and a ring gear 5. The output shaft of the engine 1 is connected to the ring gear 5 through the torsional shock absorber 2, the multi-speed transmission mechanism 3 and the first locking mechanism 4 in sequence, and the output shaft of the second motor 12 is connected to the sun gear 13 through the second locking mechanism 7. The planet carrier 6 is connected to the first transmission shaft 17 as the power output end, the first transmission shaft 17 is connected to the second transmission shaft through the first clutch 8, and the output shaft of the first moto...

The invention relates to a hybrid driving system and a hybrid vehicle. The hybrid driving system comprises an engine, a first motor, a second motor and a single-planet-row power system. The single-planet-row power system comprises a gear ring in transmission connection with an output shaft of the engine. A sun gear in transmission connection with an output shaft of the second motor and a planet carrier serving as an output end. The planet carrier is used for being connected with a drive axle through a first transmission shaft, a first clutch and a second transmission shaft in sequence. A firstlocking mechanism is arranged between an output shaft of the engine and the gear ring. A second locking mechanism is arranged between an output shaft of the second motor and the sun gear. An output shaft of the first motor is in transmission connection with the second transmission shaft. The single planet row is adopted, the structure is simple, the system efficiency is high, the arranged first clutch can disconnect power output of the engine and the second motor, switching between multiple modes can be achieved in cooperation with the two locking mechanisms, the flexibility of the driving system is improved, and multiple driving requirements are met.
Description
technical field [0001] The invention belongs to the technical field of hybrid power drive, and in particular relates to a hybrid power drive system and a hybrid power vehicle. Background technique [0002] At present, the rapid development of new energy vehicles has become a research hotspot in the current automotive industry. According to the different structural arrangements of the transmission system, the existing hybrid power systems are divided into three types: series, parallel, and hybrid. The current series hybrid system mainly uses planetary mechanism as the power splitting device. For example, the Chinese patent whose authorized notification number is CN 101318462B discloses a hybrid vehicle drive system. The drive system uses two sets of planetary mechanisms as power splitting devices, which can take into account the advantages of series and parallel systems and realize stepless speed change. However, the system has the following disadvantages: [0003] With two...
