The invention provides a planetary gear mechanism steering axle. The planetary gear mechanism steering axle comprises a steering wheel, a transmission assembly, a planetary gear steering assembly, a planet carrier and a buffer assembly, wherein the planetary gear steering assembly comprises a gear ring, a planetary gear and a sun gear, the gear ring is fixedly connected with a frame body cross beam of a vehicle, the sun gear is arranged in the center of the gear ring and is connected with the steering wheel through the transmission assembly, and the planetary gear is meshed with an inner ringof the gear ring and an outer ring of the sun gear; and the two ends of the planet carrier are connected with two wheels of the vehicle through buffer assemblies respectively, the rotating center of the planet carrier is coaxial with the sun gear, and the planet carrier is connected with the planetary gear. According to the steering axle, the defect that wheels on the two sides purely roll when the vehicle cannot steer in a traditional structure can be overcome through planetary gear steering, so the wheels on the two sides can purely roll, the steering radius is reduced, and the steering axlecan be used in steering systems of automobiles, rail vehicles and the like.
本发明提供一种行星齿轮机构转向桥,包括:转向盘、传动组件、行星齿轮转向组件、行星架、缓冲组件;其中,所述行星齿轮转向组件包括齿圈、行星齿轮以及太阳轮,所述齿圈与车辆的架体横梁固定连接,所述太阳轮设置在齿圈中心位置并通过传动组件连接转向盘,所述行星齿轮分别与齿圈内圈以及太阳轮外圈啮合;所述行星架两端分别通过缓冲组件连接车辆的两个车轮,所述行星架转动中心与所述太阳轮同轴,所述行星架连接行星齿轮。本转向桥利用行星齿轮转向可以克服传统结构中不能车辆转向时两侧车轮均作纯滚动的缺陷,使得两侧车轮能够均作纯滚动,且使得转向半径变小,可用于汽车、有轨车辆等转向系统中。
