In figure 1, traction electric machine, 2, diaphragm coupling one, 3, bearing one, 4, driving gear, 5, bearing two, 6, driven gear, 7, gear case, 8, take turns right, 9, bogie truck, 10, draw gear, 11, hollow shaft, 12, diaphragm coupling two.
Detailed description of the invention
As Fig. 1, 2 and 3 is structural representations of the present utility model, a kind of gear hollow shaft bogie truck, comprise bogie truck 9, described bogie truck 9 is provided with draw gear 10 and takes turns 8, described wheel is provided with traction electric machine 1 to 8, described traction electric machine 1 is connected by hollow shaft 11 with gear case 7, described traction electric machine 1 is connected by diaphragm coupling 1 with hollow shaft 11, described driving gear 4 is arranged on hollow shaft 11, described hollow shaft 11 is connected by diaphragm coupling 2 12 with driving gear 4, described wheel is provided with driven gear 6 to 8, described driving gear 4 engages with driven gear 6.
According to another embodiment of the present utility model, comprise further, described driving gear 4 is provided with bearing 1.
According to another embodiment of the present utility model, comprise further, described driven gear 6 and wheel are provided with bearing 25 between 8.
This gear hollow shaft bogie truck, the diaphragm coupling 1 that the moment of torsion that its traction electric machine 1 exports is held by the A of driving gear 4 passes to driving gear shaft and hollow shaft 11, then the diaphragm coupling 2 12 held by the B of driving gear 4 passes to driving gear 4, wheel is delivered to on 8 eventually through the driven gear 6 be arranged on axletree, bogie truck 9 is provided with driving gear 4 hollow shaft 11 structure, greatly can reduce traction electric machine 1 and the shock and vibration of gear pair under high speed rotating state, make moment of torsion transmission more stable, improve gear and use condition, extend gear pair service life.
