The invention provides a variable gauge locomotive wheelset axle box device, and relates to the technical field of locomotive production and manufacturing. The variable gauge locomotive wheelset axle box device comprises an axle box beam, a locking frustum and a plurality of locking bosses arranged in the axial direction of an axle are arranged on the inner wall of the upper end of the axle box beam, and a locking stop is arranged on the outer wall of the lower end of the axle box beam; the axle box body is arranged in the axle box beam, and a locking conical groove is formed in the outer wall of the axle box body; the sliding mechanism is arranged outside the axle box body and arranged on the wheels in a penetrating mode. The sliding mechanism is provided with a plurality of locking clamping grooves formed in the axial direction of the axle and a plurality of locking grooves formed in the axial direction of the axle. The sliding mechanism is configured to drive the wheels to move in the axial direction of the axle, so that the locking conical grooves are selectively clamped to the locking frustums, the at least one locking boss is selectively clamped to the corresponding locking clamping groove, and the locking stop is selectively clamped to one of the multiple locking grooves. The bearing is large and the strength requirement is met.

    本发明提供一种变轨距机车轮对轴箱装置,涉及机车生产制造技术领域。该变轨距机车轮对轴箱装置,包括轴箱梁,轴箱梁上端的内壁设置有锁紧锥台和多个沿车轴的轴向方向设置的锁紧凸台,轴箱梁下端的外壁设置有锁紧止挡;轴箱体设置于轴箱梁内,轴箱体的外壁设置有锁紧锥槽;滑移机构设置于轴箱体的外部并穿设于车轮,滑移机构设置有多个沿车轴轴向方向设置的锁紧卡槽和沿车轴轴向方向设置的锁紧凹槽;滑移机构配置为带动车轮沿车轴的轴向方向移动,使锁紧锥槽选择性卡接于锁紧锥台,至少一个锁紧凸台选择性和与其相对应的锁紧卡槽相卡接,锁紧止挡选择性与多个锁紧凹槽之一相卡接。承载大,满足强度需求。
