Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail:
As depicted in figs. 1 and 2, a kind of Suspension device for traction motor of rail vehicle, comprise traction electric machine 1 and framework, concrete, traction electric machine 1 is fixedly mounted on the crossbeam 2 in framework, and the side of traction electric machine 1 is fixedly connected with by four rubber nodal points 3 with between crossbeam 2, and four rubber nodal points 3 are divided into two, top and following two, four rubber nodal point 3 Absorbable rod are vertical, longitudinal direction, transverse vibration energy, and then effectively reduce bogie truck vibration.Meanwhile, adopt four rubber nodal points 3 to be fixedly connected with, even if damage one because of abnormal cause, its excess-three also can ensure the normal suspension work of traction electric machine 1, and safety allowance is high.
As shown in Figure 3, respective independently four hangers 4 are provided with in the side of traction electric machine 1, corresponding four rubber nodal points 3, hanger 4 is also set to upper and lower two rows, each hanger 4 is roughly triangular in shape, the bottom welding of each hanger 4 is fixed on the shell of traction electric machine 1, has a sleeve 5 at the leading section of hanger 4, in each sleeve 5, install a rubber nodal point 3.
As shown in Figure 4, rubber nodal point 3 is made up of the mandrel of centre and the rubber 16 of outer ring, respectively stretches out a connecting portion 6, connecting portion 6 is offered through hole 7 in the both sides of mandrel, and middle rubber 16 part is set in sleeve 5, and connecting portion 6 stretches out to both sides.
As depicted in figs. 1 and 2, the crossbeam 2 of framework is provided with mount pad 8, conveniently rubber nodal point 3 is installed, in the present embodiment, mount pad 8 is made up of four adapter plates 9 of vertical setting, and four adapter plates 9 are parallel to each other and are fixed on crossbeam 2, are welded and fixed between adapter plate 9 and crossbeam 2.Four adapter plates 9 are divided into two groups, left and right, upper and lower two rubber nodal points 3 in left side are together with between adjacent two adapter plates 9 in one group, the sleeve 5 insertion left side of hanger 4 end, and upper and lower two rubber nodal points 3 on right side are together with between adjacent two adapter plates 9 in one group, the sleeve 5 insertion right side of hanger 4 end.
