The invention relates to train wheel lubrication, in particular to a dry-type wheel rim lubricating device and a dry-type train wheel rim lubricating method.The dry-type wheel rim lubricating device comprises a channel, a magnetic attraction part and a pressure applying part; one end of the channel is open, and the opening is used for arranging a lubricating block abutting against a wheel rim; the magnetic attraction part is arranged in the channel in a sliding manner; the pressure applying part is located on one side of the magnetic attraction part, abuts against the magnetic attraction part and is used for continuously applying thrust towards the opening direction to the magnetic attraction part. The dry wheel rim lubricating device further comprises an outer electromagnetic part which is arranged on the side of the channel and extends in the length direction of the channel. During electrification, the outer electromagnetic part and the magnetic attraction part are attracted to fix the position of the magnetic attraction part in the channel; when power is cut off, the magnetic attraction part loses attraction and then transmits the thrust of the pressure applying part to the lubricating block. According to the scheme, the thrust applied to the lubricating block is controlled by adopting an electromagnet attraction and release control mode, so that the consumption of the lubricating block is effectively and accurately controlled, and the continuous consumption of the lubricating block is reduced.

    本发明涉及列车轮润滑,特别涉及一种干式车轮缘润滑装置及干式列车轮缘润滑方法,干式车轮缘润滑装置,包括通道,磁吸部和施压部;通道的一端开口,开口用于布置与车轮缘抵接的润滑块;磁吸部可滑动布置于通道内;施压部位于磁吸部一侧并与该磁吸部抵接,用于持续对磁吸部施加朝向开口方向的推力。本干式车轮缘润滑装置还包括外电磁部,外电磁部布置于通道侧方并沿通道长度方向延伸;用于通电时,外电磁部与磁吸部吸引以使磁吸部在通道内位置固定;断电时,磁吸部失去吸引后将施压部的推力传递给润滑块。本方案采用电磁铁吸合及释放的控制方式对润滑块受到推力进行控制,从而实现润滑块消耗得到有效的较为精准的控制,减少润滑块持续消耗。
