The invention discloses a supporting-frame-free locomotive rear wheel and a locomotive. The rear wheel comprises a first wheel, a second wheel, a mounting shaft, an elastic piece and a release lockingmechanism. The first wheel is rigidly connected with the mounting shaft, and the second wheel is connected with the mounting shaft in a penetrating manner and can slide along the mounting shaft; theelastic piece is arranged on a part of the mounting shaft between the first wheel and the second wheel in a sleeving manner; and the release locking mechanism is arranged at an end part of the mounting shaft on an outer side of the second wheel. The locomotive comprises the locomotive rear wheel without the supporting frame. The rear wheel is divided into two parts to complete three supporting points needed by locomotive parking, parking convenience is improved, and meanwhile when one of the two rear wheels cannot work, the other rear wheel can still support the locomotive to continue to run.

    本申请公开了一种免支撑架的机车后轮及机车,该后轮包括:第一轮、第二轮、安装轴、弹性件以及释放锁定机构,其中,所述第一轮与所述安装轴刚性连接,所述第二轮与所述安装轴贯穿连接并可沿所述安装轴滑动;所述弹性件套设在所述第一轮和所述第二轮之间的部分所述安装轴上;所述释放锁定机构设置在所述第二轮外侧的所述安装轴的端部。一种机车,包括上述的免支撑架的机车后轮。本申请把后轮一分为二的方式完成机车停放所需要的三个支撑点,提高了停放便捷性,同时两个后轮在其中一个不能工作时另一个依然能支持机车继续行驶。
