The two-gear speed reducer comprises an input shaft, a transmission shaft, a planet row and an output shaft, and the planet row comprises a first planet gear, a second planet gear, a sun gear, an inner gear ring and a planet carrier; a synchronizer rotating synchronously is arranged on the input shaft, a first duplicate gear and a second duplicate gear are rotationally arranged on the input shaft on the two sides of the synchronizer respectively, the first duplicate gear comprises a first gear and a second gear close to the synchronizer, and the second duplicate gear comprises a third gear close to the synchronizer and a sun gear; a fourth gear rotating synchronously and a second planet gear rotating synchronously are arranged on the transmission shaft, and the fourth gear is meshed with the first gear; the output shaft is fixed to the inner gear ring and is coaxial with the inner gear ring. The optimal two-gear speed ratio difference strategy can be provided according to the requirements of the whole vehicle, and the matching difficulty of the whole vehicle is low; and the design and manufacturing are easy, the input shaft and the output shaft are not coaxial, and the space can be effectively utilized.
本发明公开了一种两档减速器及具有其的轮边驱动系统,包括输入轴、传动轴、行星排和输出轴,行星排包括第一行星轮、第二行星轮、太阳轮、内齿圈和行星架;输入轴上设置有同步转动的同步器,同步器两侧的输入轴上分别转动设置有第一双联齿轮和第二双联齿轮,第一双联齿轮包括第一齿轮和靠近同步器的第二齿轮,第二双联齿轮包括靠近同步器的第三齿轮和太阳轮;传动轴上设置有同步转动的第四齿轮和同步转动的第二行星轮,第四齿轮与第一齿轮啮合;输出轴固定于内齿圈上,且与内齿圈同轴布置。可以根据整车要求,提供最优的两档速比差距策略,整车匹配难度低;而且设计制造容易,输入轴与输出轴不共轴,可以有效利用空间。
