Abstract

The invention relates to a metro vehicle maintenance technology, in particular to a multi-stage transmission axle gear box. The multi-stage transmission axle gear box comprises a box body, an input shaft, an output shaft and a multi-stage gear transmission assembly, wherein the input shaft is transversely and rotatably assembled on the inner walls of the two sides of one end of the box body; an input gear is arranged on the input shaft; the output shaft is transversely and rotatably assembled on the inner walls of the two sides of the other end of the box body; an output gear is arranged on the output shaft;and the multi-stage gear transmission assembly is assembled in the box body and in transmission connection with the input gear and the output gear respectively. The multi-stage transmission axle gear box has the advantages that the transmission ratio is large, the multi-stage transmission is adopted, under the same power, limited space can be used, the speed reduction degree and the driving force are large, and the traction requirements can be met.

Description

technical field [0001] The invention relates to the maintenance technology of subway vehicles, in particular to a multi-stage transmission axle gear box. Background technique [0002] After a certain period of use of subway vehicles, all parts will be worn, deformed or damaged. In order to make the subway vehicles run stably and reliably in good condition and extend the service life, the subway vehicles must be inspected in a planned way according to the maintenance process requirements and overhaul. When the subway vehicle is repaired above the level of frame repair, the process bogie is required to replace the bogie support in the subway vehicle and move the car body to the designated maintenance station for maintenance. [0003] At present, the transmission ratio of the traditional bogie gearbox is generally less than 10, the transmission ratio is small, the degree of deceleration is small, the driving force is small, and the space utilization rate is insufficient. Con...
