The invention provides a train bogie wheel set pitch changing device which comprises wheels, an axle and an axle box body arranged on the axle in a sleeving mode, a sliding axle sleeve is connected to the axle in a sliding mode, the wheels are fixedly arranged on the sliding axle sleeve in a sleeving mode, and the wheels are located on the outer side of the axle box body; the limiting bearing sleeve is arranged in the axle box body and rotationally arranged on the sliding axle sleeve in a sleeving mode, a limiting ring is arranged between the limiting bearing sleeve and the axle box body, the limiting ring can lock the limiting bearing sleeve and the axle box body, at the moment, the wheel is axially locked, the limiting ring is separated from the limiting bearing sleeve by pushing the limiting ring to move, and therefore the wheel is locked. The wheel track changing of the train bogie wheel set can be conveniently and efficiently achieved, the research, development, production and manufacturing cost of a variable-pitch bogie can be greatly reduced, and the universal popularization and landing application are facilitated.

    本发明提供一种列车转向架轮对变距装置,包括车轮、车轴以及套设在车轴上的轴箱体,在车轴上可滑动连接有滑动轴套,车轮固定套设在滑动轴套上,车轮位于轴箱体外侧;还包括设置在轴箱体内部的限位轴承套,限位轴承套转动套设在滑动轴套上,在限位轴承套与轴箱体之间设置有限位环,限位环能将限位轴承套与轴箱体锁紧,此时车轮轴向锁定,通过推动限位环移动,使限位环脱离限位轴承套,此时车轮轴向解锁,能便捷高效的实现列车转向架轮对的变轮距,能大幅度降低变距转向架的研发和生产制造成本,利于普遍推广和落地应用。
