If the locomotive cannot run due to faults, rescue is needed, the transportation order is influenced, in order to minimize the influence, the fault locomotive must be safely driven away as soon as possible, the occupied area is rapidly opened, and the influence on the railway transportation order is reduced to the greatest extent.
The bogie driving device is a key part of a locomotive and mainly comprises a traction motor 4, a shaft holding box 9, a gear box 7, a driving gear, a driven gear and the like. If the wheel set rolling locking bearing, traction motor bearing and other parts are burnt out and dead-fixed in the running process, rescue measures must be taken when the wheel set is dead-fixed and can not rotate. As shown in fig. 1, the driving device is mainly divided into a rolling axle-locking semi-suspension type and a frame suspension type according to the installation mode of the traction motor on the bogie. The semi-suspension mode is as follows: one end is supported on the axle through two rolling bearings respectively installed in the axle-holding box 9, and the other end is suspended on the bogie frame through the motor suspender 6.

The first is to use a specialized rescue trolley to jack up the fault drive or bogie and leave the wheels from the ground. The failed motor may be removed by the control system of the locomotive, or the locomotive may be disabled and pulled to the service location by other locomotives. The following disadvantages are mainly present:
(1) When the rescue trolley is used, the running speed of the locomotive needs to be limited, the straight line section of the main line does not exceed 25km/h, the curve of the main line does not exceed 20km/h, and the curve of the main line does not exceed 15km/h when passing through a turnout.
(2) The use safety risk of the rescue trolley mainly comprises deformation and damage of the substitute trolley, separation of wheels and the trolley, derailment and the like.
(3) The rescue device is only suitable for short-distance rescue.
The second type is a rescue loopback disposal scheme with a fault position wheel set suspending away from the rail surface, the technical requirement for implementing the scheme is high, the technical requirement is needed to be guided by professional staff, and the implementation process is complex. The suspension of the wheel set is realized, the axle box spring is generally required to be taken out or cut off, and then the whole driving device is bound to the framework through the axle box body, the iron chain, the lifting appliance and the like. The following disadvantages are mainly present:
