The two cross members 12 divide the space between the two side members 11 into three mounting spaces. The side beams 11 and the cross beams 12 can be box-shaped structures, and the two side beams 11 and the two cross beams 12 are welded to form an H-shaped framework.
The number of the wheel sets 3 is three, and one set of the wheel sets 3 is positioned in one installation space. The wheel set 3 comprises: axle 32, wheels 31 symmetrically disposed on axle 32, and axle boxes 33, axle boxes 33 being located below side members 11.
A suspension device 4 is provided between the axle box 33 and the side member 11. The secondary suspension device 5 is provided in the middle of the side member 11. The traction device 6 is disposed below the side member 11, connected to the vehicle body, and transmits longitudinal force, including traction force and braking force, between the bogie and the vehicle body.
The technical scheme that this embodiment provided adopts two curb girders and two crossbeams to connect into H shape framework, compares in traditional "mesh" font framework and compares, "H" shape framework in this application does not have the end beam, has alleviateed the dead weight of bogie.

In the wheel pair 3, the wheels 31 and the axle 32 are fixedly connected through a press-fitting process, and the axle box 33 includes a box body and a bearing arranged in the box body, and the bearing is press-fitted between the axle 32 and the box body. The box body is a casting part, adopts a seesaw structure and provides an interface for a series of suspension devices.
The primary suspension device 4 includes: two sets of steel spring assemblies 41 and vertical shock absorbers 44. Two sets of steel spring assemblies 41 are disposed between axle boxes 33 and side members 11. The two sets of steel spring assemblies 41 are arranged in series in a longitudinal direction parallel to the side beams 11.

The composite rubber guide post 42 can meet the vibration damping in the vertical and horizontal directions. The primary suspension adopts a double-spring guide post structure, so that the arrangement of axle box pull rods is reduced, the axle distance of the bogie and the length of a framework are shortened, and the bogie is more compact while the weight of the framework is reduced.
In conventional solutions, the distance between the wheel sets, i.e. the wheelbase of the bogie, is relatively large by using a tie rod extending in the longitudinal direction between the axlebox and the frame.

For example: the traction device 6 adopts a double-side flat pull rod structure, spans the bottom of the framework 1, and is arranged below the side beam 12, so that the height of a vehicle traction point is reduced, and the vehicle adhesion utilization rate is convenient to improve.
Specifically, the traction device 6 includes: a balance bar 61, a crank arm 62 and a pull bar 63. The crank arms 62 are rotatably disposed on the lower surfaces of the side members 11, and the crank arms 62 are correspondingly disposed on the two side members 11.

The pull rod 63 extends in the longitudinal direction, and has one end rotatably connected to the crank arm 62 and the other end for connection to the vehicle body. The crank arm 62, the balance bar 61 and the pull rod 63 move relatively in the same horizontal plane.
In the conventional scheme, the traction device extends along the vertical direction, the top of the traction device is connected with the vehicle body, and the bottom of the traction device is matched with the framework, so that the height of a vehicle traction point is higher. In this embodiment, the crank arm 62, the balance bar 61 and the pull rod 63 move relatively in the same horizontal plane, so as to transmit longitudinal force to the vehicle body, reduce the height of the traction point, reduce the height of the vehicle body, further reduce the center of gravity of the vehicle body, improve the adhesion utilization rate of the vehicle, and further improve the safety and stability. Moreover, the traction device has a simple structure, reduces a plurality of parts and oil injection press-fitting processes, and reduces the manufacturing cost.

Further, the number of the driving devices 2 is three, and the driving devices 2 are respectively arranged in one installation space, and one driving device 2 correspondingly drives the axle 32 in one wheel pair 3 to rotate, so that one-to-one driving is realized, and high driving force is provided. The two driving devices 2 positioned at the longitudinal two ends of the bogie are in central symmetry with the center of the bogie, so that the center of mass of the traction motor is close to the center of mass of the bogie, and the rotational inertia is reduced.
The wheel diameter of the wheel is 840 or 915 series according to the axle weight requirement, and the wheel diameter is smaller than that of the conventional bogie. Because the bogie of the application adopts the H-shaped framework with the double side beams and the double cross beams, and three sets of wheel sets share the load of the vehicle body, the load born by each set of wheel set can be reduced, and therefore, the wheels with smaller wheel diameters can be adopted, the height of the bogie can be favorably reduced, and the gravity center of the vehicle body can be reduced.
