The invention relates to the technical field of axle protection, and discloses a railway vehicle axle safety protection mechanism which comprises an axle body, cast steel wheels are fixedly connected to the two sides of the outer wall of the axle body, a protection shell is fixedly connected to one side of the outer wall of each cast steel wheel and used for protecting the axle body, and a clearing mechanism is fixedly connected to one side of the outer wall of the axle body and used for clearing the axle body. The cleaning mechanism is used for cleaning the outer wall of the cast steel wheel, and a lubricating assembly is arranged on one side of the outer wall of the cleaning mechanism and used for lubricating the joint of the axle and the cast steel wheel. By cleaning residual dirt on the outer wall of the cast steel wheel, uniform weight distribution of the cast steel wheel is guaranteed, and then balance of the two ends of the shaft body is maintained. The problems of vibration, stress increase and the like caused by unbalance of the shaft body are avoided, and the running stability of a train is remarkably improved. In the long-term operation process, part abrasion and fatigue damage caused by unbalance of the axle body are reduced, and the service life of the axle and related parts is prolonged.
本申请涉及车轴防护技术领域,公开了一种铁道车辆车轴安全防护机构,包括轴体,所述轴体的外壁两侧固定连接有铸钢轮,所述铸钢轮的外壁一侧固定连接有防护壳,其用于对轴体进行防护,所述轴体的外壁一侧固定连接有清除机构,其用于对铸钢轮的外壁进行清理,所述清除机构的外壁一侧设置有润滑组件,其对车轴与铸钢轮的连接处进行润滑。通过清理铸钢轮外壁的残余污垢,保证了铸钢轮的重量均匀分布,进而维持轴体两端的平衡。避免了因轴体不平衡导致的振动和应力增加等问题,显著提高了列车运行的稳定性。在长期的运行过程中,减少了因轴体不平衡引起的部件磨损和疲劳损伤,延长了车轴及相关部件的使用寿命。
