The invention is suitable for the technical field of automobiles, and provides a low-cost electric steering column speed reducing mechanism which comprises an upper steering shaft assembly. An input shaft of the upper steering shaft assembly is connected with an automobile steering wheel, and an output end of the upper steering shaft assembly is connected with a ten-tooth spline shaft; a speed reducer is arranged on one side, far away from the upper steering shaft assembly, of the ten-tooth spline shaft; the speed reduction device comprises a supporting cover arranged on the outer side of the ten-tooth spline shaft. The lubricating device is arranged in the supporting cover; the production cost is greatly reduced through simplified design, meanwhile, efficient torque transmission is achieved through the unique worm and gear speed reduction device, the steering precision is remarkably improved, the system reliability is enhanced by means of the self-locking characteristic, accidental movement of a vehicle under the unstable condition is effectively prevented, and in addition, the system is suitable for large-scale popularization and application. The exquisite lubricating device ensures smooth operation of the meshing portion of the worm gear and the worm, abrasion is remarkably reduced, the service life is prolonged, and the stability and reliability of the system are further enhanced.

    本发明适用于汽车技术领域,提供了一种低成本的电动转向管柱减速机构,包括上转向轴总成;上转向轴总成的输入轴与汽车转向盘相连接,上转向轴总成的输出端连接有十齿花键轴;十齿花键轴远离上转向轴总成的一侧设置有减速装置;减速装置包括设置在所述十齿花键轴外侧的支撑盖;设于支撑盖内的润滑装置;本发明通过精简设计大幅降低了生产成本,同时其独特的蜗轮蜗杆减速装置实现了高效力矩传递,显著提升了转向精度,并凭借自锁特性增强了系统可靠性,有效防止了车辆在不稳定条件下的意外移动,此外,精巧的润滑装置确保了蜗轮蜗杆啮合部位的顺畅运转,显著减少了磨损,延长了使用寿命,进一步增强了系统的稳定性和可靠性。
