The invention provides a universal joint assembly structure for a steering column, a universal joint transmission device and an automobile. The universal joint assembly structure for the steering column comprises a besides-star wheel fixedly connected with a driven shaft, and a plurality of outer fairways evenly distributed in the circumferential direction are formed in the inner side of the besides-star wheel; an inner spline hole is formed in the center of the inner star wheel, and a plurality of inner ball grooves which are uniformly distributed in the circumferential direction are formed in the outer side of the inner star wheel; the steel balls are arranged between the outer fairway and the inner fairway; the ball cage enables the ball centers of the steel balls to be kept in the same plane; the shaft head is fixedly connected with the driving shaft, the end part of the shaft head is provided with an outer spline shaft meshed with the inner spline hole, the end part of the shaft head is also provided with a round clamp spring clamped and positioned with the inner star wheel, and the end part of the shaft head is riveted and connected with the inner star wheel. According to the technical scheme, it can be ensured that the shaft head cannot be disengaged from the inner star wheel, and therefore the steering control mechanism can effectively and reliably work.

    本发明提供一种转向管柱用万向节总成结构、万向节传动装置及汽车。所述转向管柱用万向节总成结构包括与从动轴固定连接的外星轮,所述外星轮内侧设有周向均匀分布的多个外球道;中心开设有内花键孔的内星轮,所述内星轮外侧设有周向均匀分布的多个内球道;多个设置在所述外球道和内球道之间的钢球;使多个所述钢球的球心保持在一个平面内的球笼;与主动轴固定连接的轴头,所述轴头的端部开设有与内花键孔相啮合的外花键轴,所述轴头的端部还设有与内星轮呈卡接定位的圆形卡簧,所述轴头的端部与内星轮铆合联接。本发明的技术方案能确保轴头不会从内星轮中脱出,从而转向操纵机构可以有效可靠工作。
