Introduction Of Wheelset And Axle Box Of Mining Electric Locomotive

The wheelset and axle box of a mining electric locomotive are formed by pressing two wheels on one axle. There are two types of wheels, one is a structure in which the wheel hub and the wheel core are hot-pressed together; the other is an integral wheel. The former has the advantage that when the tyre is worn to the limit, only the tyre is replaced without the entire wheel being scrapped.

The driving wheel pair of a mining electric locomotive has a transmission gear, and the motor reduces the gear to drive the wheel pair to rotate.

The sliding grooves on both sides of the axle box are matched with the guide rails on the frame. There are seat holes on which the spring brackets are placed.

The frame of the mining electric locomotive is supported on the axle box by a spring bracket, which is the connection point between the frame and the wheelset. When the track is uneven, the relative movement of the wheelset and the frame occurs between the chute of the axle box and the guide rail of the frame, and the spring bracket acts as a buffer.
