Drawings
FIG. 1 is a schematic view of the present invention;
fig. 2 is a schematic view of the framework structure of the present invention.
Detailed Description
The technical solution in the embodiment of the present invention will be clearly and completely explained below with reference to the drawings in the embodiment of the present invention.
A bogie for a subway flat car comprises a wheel set 1, wherein two ends of the wheel set 1 are provided with a wagon rolling bearing device 12, an axle box 6 is arranged at the upper part of the wagon rolling bearing device 12, two ends of the axle box 6 are provided with an inner circle spring 4 and an outer circle spring 5 of an unequal height spring group, an inclined wedge shock absorber 3 is arranged on the inner circle spring 4 and the outer circle spring 5 of the unequal height spring group, the upper part of the inclined wedge shock absorber 3 is connected with a guide frame 13 in a framework 2, the upper part of the guide frame 13 is fixedly connected with a side beam 14 in the framework 2, the lower part of the side beam 14 is fixedly connected with a sliding chute 15, two ends of a sleeper beam 16 in the framework 2 are fixedly connected with the two side beams 14 respectively, the upper parts of two ends of the sleeper beam 16 are fixedly connected with a side bearing box 17, two sides of the sleeper beam 16 are fixedly connected with hanging seats 19, one side of the sleeper beam 16 is fixedly connected with a fixed fulcrum seat 18, the upper part of the sleeper beam 16 is connected with a lower center plate 10 through a fastener 11, a center plate abrasion plate 7 is arranged in the lower center plate 10, a double-acting elastic side bearing box 17 is arranged in the same, a basic brake device 9 is connected with a suspension seat in a sliding contact with the sliding chute 15. The body of the subway flat car is placed inside the center plate abrasion plate 7 through the center plate of the body.
The utility model discloses a round spring and excircle spring in the height that varies, only excircle spring bears during the empty wagon, and the round spring just can bear when the external load reachs certain time, has improved empty wagon spring static deflection like this, the effectual dynamic behavior who improves the empty wagon.
