Embodiment Construction
[0035] like Figure 1~4 As shown, a B0 bogie for a concentrated power EMU includes a sun-shaped frame 2, a wheel set 3, and a single drawbar 1.
[0036] The end beam of the frame 2 is provided with a frame fifth wheel 105, one end of the single draw bar 1 is connected to the frame fifth wheel 105 through the first fifth wheel 106, and the other end is connected to the vehicle body chassis 101 through the second fifth wheel 107. superior. The height of the end of the single drawbar 1 connected to the frame fifth wheel 105 is lower than the height of the end connected to the vehicle body chassis 101 .
[0037] The wheel diameter of the wheel set 3 is 1050mm, and the intersection point A (namely the nominal traction point) of the extension line of the axis of the single drawbar 1 and the center line of the frame is 60mm from the rail surface.
[0038] It also includes secondary springs 403 arranged on the frame side beams 202, two secondary springs 403 are arranged at intervals...
