Train wheel and railway turnout matched with train wheel

ZHOU YUREN

The invention discloses a train wheel and a railway turnout matched with the train wheel. The train wheel comprises a rotating shaft, wheels are installed at two ends of the rotating shaft, outer wheel flanges are arranged on the wheels, and the outer wheel flange on one wheel is located on an end surface, deviating from the other wheel, of the wheel. The railway turnout comprises a turnout switchrail and a movable point rail, the turnout switch rail is located at a bifurcation position of two intersecting rails, two steel rails in the turnout switch rail are located on the outer sides of thetwo steel rails located on the outermost side in the two intersecting rails respectively, and a tip of the movable point rail faces a direction deviating from the turnout switch rail. A friction force and a stress which are generated by an outer wheel flange structure of the train wheel and hinder inclination are located on the other side different from an inclination or rollover fulcrum, the armof force of a friction force moment and a stress moment for resisting rollover is larger, the friction force moment and the stress moment are larger too, and a rollover resisting capacity is higher.

本发明公开了一种火车车轮及与其相适配的铁路道岔，该火车车轮包括转轴，转轴两端均安装有车轮，车轮上设有外轮缘，一个车轮上的外轮缘位于该车轮背离另一个车轮的端面上。该铁路道岔包括道岔尖轨和活动心轨，道岔尖轨位于两条相交路轨的分岔处，且道岔尖轨中的两根钢轨分别位于两条相交路轨中位于最外侧的两根钢轨的外侧，活动心轨的尖头朝向背离道岔尖轨的方向。该火车车轮的外轮缘结构产生的阻碍倾斜的摩擦力及应力在与倾斜或侧翻支点不同侧的另外一侧，抗侧翻的摩擦力力矩及应力力矩的力臂更大，摩擦力力矩和应力力矩也更大，抗侧翻的能力也更强。
