According to the guide mechanism and the railway vehicle, the guide support is hinged to the guide frame, the guide wheel is installed at the front end of the guide support, then the limiting column is inserted into the limiting hole provided with the damping ring, and in the running process of the railway vehicle, the guide wheel moves forwards along the guide rail and is disturbed by unsmooth excitation from the guide rail; after the guide wheel is disturbed, torque with a hinge point as a central point can be generated, the torque causes elastic deformation of the damping ring, pressure borne by the guide wheel is effectively offset, the adverse effect of guide rail disturbance on transverse stability of a vehicle can be effectively relieved, the requirement for elasticity of the guide wheel is lowered, and the service life of the guide wheel is prolonged. The guide wheel can be made of materials with high hardness, so that the abrasion resistance is improved, and the service life is prolonged.
本发明提供的一种导向机构及轨道车辆,通过将导向支架与导向框架铰接,并将导向轮安装在导向支架的前端,再将限位柱插入设置有阻尼环的限位孔内,轨道车辆行驶过程中,导向轮沿着导向轨前进并受到来自导向轨不平顺的激扰,导向轮受激扰后会产生一个铰接点为中心点的力矩,该力矩引起阻尼环的弹性变形,有效的抵消了导向轮受到的压力,既能够有效的缓解导向轨激扰对车辆横向平稳性的不利影响,也降低了对导向轮的弹性要求,使得导向轮可以采用硬度比较高的材料制作,以提高耐磨性能和使用寿命。
