The invention discloses a grounding device, a bogie and a rail transit locomotive vehicle. The grounding device comprises a shell, a carbon brush holder arranged in the shell, a carbon brush being arranged in a brush groove in a sliding manner and being electrically connected with the carbon brush holder, an elastic piece, and a grounding cable. The carbon brushis provided with a contact surface which can be attached to the peripheral surface of the axle; the elastic piece is arranged between the carbon brush and the carbon brush holder or between the carbon brush and the shell and drives thecontact surface of the carbon brush to be in contact with the peripheral surface of the axle; and the grounding cable is arranged on the shell and is electrically connected with the carbon brush holder. Because the carbon brush is electrically connected with the carbon brush holderand the carbon brush holder is electrically connected with the grounding cable, the current flows into the axle through the grounding cable, the carbon brush holder and the carbon brush in sequence and is finally guided into the steel rail. Compared with the prior art, the grounding device has the following characteristics: a contact disc is omitted, parts are simplified, and resistance is reduced. The grounding device encircles the axle instead of being installed at the axle end and thus the length of the axle cannot be increased, so that the length of the axle can be controlled easily and the influence of the grounding device on the axle length is reduced.
本发明公开了一种接地装置、转向架和轨道交通机车车辆，包括壳体；设置在壳体内部的碳刷架；可滑动的设置在刷槽内并与碳刷架电连接的碳刷，碳刷具有能够与车轴的周面相贴合的接触面；置于碳刷与碳刷架之间或碳刷与壳体之间并驱动碳刷的接触面与车轴的周面接触的弹性件；和设置在壳体上并与碳刷架电连接的接地电缆。由于碳刷与碳刷架电连接，碳刷架与接地电缆电连接，因此，电流依次通过接地电缆、碳刷架和碳刷流入车轴，并最终导入钢轨。与现有技术相比：省略了接触盘，具有简化零部件，减小电阻的特点。将接地装置环抱车轴而不是安装在轴端，不会增加车轴的长度，有利于控制车轴长度，降低了接地装置对车轴长度的影响。
