The invention discloses a hybrid power four-gear transmission, a hybrid power driving system and a hybrid power vehicle. The technical problem that an existing hybrid power four-gear transmission is complex in structure is solved. The hybrid power four-gear transmission comprises a box body, a single planet row, a first executing mechanism, a second executing mechanism, a first parallel gear shifting gear, a second parallel gear shifting gear and an output transmission mechanism. A gear ring and a sun wheel shaft of the single planet row are used for transmitting torque of an engine and torque of a first motor respectively. Due to the fact that power flow of the engine is input through the gear ring and output through the planet carrier/sun wheel shaft, compared with the power form of planet carrier input and gear ring output in the prior art, larger torque can be obtained at the output end of the planet row, the power performance is good, only one planet row needs to be arranged, and the structure is simplified. And the first executing mechanism and the second executing mechanism are connected with the planet carrier and the sun wheel shaft correspondingly, no external gear is arranged on the gear ring, and the structure of the hybrid power four-gear transmission is further simplified.
本发明公开了一种混合动力四挡变速器、混合动力驱动系统及混合动力车辆,解决目前混合动力四挡变速器结构复杂的技术问题。本发明的混合动力四挡变速器包括箱体、单行星排、第一执行机构、第二执行机构、第一平行换挡齿轮、第二平行换挡齿轮和输出传动机构,单行星排的齿圈和太阳轮轴分别用于传递发动机和第一电机的扭矩。由于发动机动力流是由齿圈输入,行星架/太阳轮轴输出,相比于现有技术中行星架输入、齿圈输出的动力形式,本申请能够在行星排的输出端获得更大的扭矩,动力性好,仅需配置一个行星排即可,简化结构。并且第一执行机构、第二执行机构分别与行星架和太阳轮轴连接,齿圈上无外接齿轮,进一步简化该混合动力四挡变速器的结构。
