The invention provides a speed change mechanism which comprises a speed change planet row, the speed change planet row comprises a first sun gear, a planet carrier, a duplex planet gear, a first gear ring and a second gear ring, and the duplex planet gear, the first gear ring and the second gear ring are rotatably arranged on the planet carrier; the duplex planet gear comprises a first planet gear and a second planet gear which are fixedly connected with each other, the first planet gear is meshed with the first sun gear and the first gear ring at the same time, the second planet gear is meshed with the second gear ring, and the first sun gear is fixedly connected with the input shaft to input power; the first gear shifting element selectively connects the second gear ring or the planet carrier with the output shaft, and the second gear shifting element selectively keeps the first gear ring or the second gear ring fixed. The invention further provides an electric driving device and a hybrid power driving device. By the adoption of the compound planet row and the two gear shifting elements, at least three gears can be achieved, the first-gear speed ratio can reach a large numerical value, at least one stage of reduction gear can be omitted, and the speed change mechanism with the excellent comprehensive performance is obtained.

    本发明提供一种变速机构,包括变速行星排,变速行星排包括第一太阳轮、行星架及可转动地安设在其上的双联行星轮、第一齿圈和第二齿圈;双联行星轮包括相互固定连接的第一行星轮和第二行星轮,第一行星轮与第一太阳轮和第一齿圈同时啮合,第二行星轮与第二齿圈啮合,第一太阳轮与输入轴固定连接以输入动力;第一换挡元件和第二换挡元件,第一换挡元件可选择地将第二齿圈或行星架与输出轴接通,第二换挡元件可选择地将第一齿圈或第二齿圈保持固定。本发明还提供了一种电驱动装置和混合动力驱动装置。通过采用一个复合行星排和两个换挡元件,可实现至少三个挡位且1挡速比可达到较大数值,可省去至少一级减速齿轮,得到一种综合性能较优的变速机构。
