The embodiment of the invention provides a grounding device, a bogie and a railway vehicle, the grounding device comprises a friction disc and a carbon brush assembly, and the friction disc sleeves anaxle; the carbon brush assembly comprises a shell, and the shell is connected with the bogie; a cavity is formed in the shell, a notch connected with the cavity is formed in the shell, at least partof the friction disc is arranged in the notch, at least one carbon brush is arranged in the cavity, one end of the carbon brush abuts against the friction disc, and the other end of the carbon brush is connected with the shell. According to the embodiment of the invention, the friction disc is connected with the axle, the carbon brush assembly is arranged on the radial outer side of the friction disc, the carbon brush of the carbon brush assembly abuts against the friction disc, and a current is guided to the rail through the axle and the wheels, so that grounding connection is realized. According to the embodiment of the invention, direct connection between the carbon brush and the axle is avoided, and the carbon brush is installed in an area with sufficient external space of the axle, thereby facilitating maintenance and replacement of the grounding device.
本申请实施例中提供了一种接地装置、转向架及轨道车辆,接地装置包括摩擦盘和碳刷组件,摩擦盘套设在车轴上;碳刷组件包括壳体,壳体与转向架相连接;壳体内形成有空腔,壳体上设有连接空腔的豁口,摩擦盘的至少部分设置在豁口内,空腔内设有至少一个碳刷,碳刷的一端抵接在摩擦盘上,碳刷的另一端与壳体相连接。本申请实施例通过摩擦盘与车轴相连接,并在摩擦盘的径向外侧设置碳刷组件,碳刷组件的碳刷抵接在摩擦盘上,通过车轴和车轮将电流导向轨道,以实现接地连接。本申请实施例避免了碳刷与车轴的直接连接,将碳刷安装在车轴外部空间较充裕的区域,方便接地装置的维修和更换。
