Embodiment 1

[0039] figure 1 Shown in is a schematic structural diagram of a bogie provided by an embodiment of the present application; figure 2 Shown in is the bottom view structural diagram of the bogie provided by an embodiment of the present application; image 3 Shown in is the bottom view structural diagram of the bogie provided by another embodiment of the present application; Figure 4 Shown in is a schematic structural diagram of the framework provided by an embodiment of the present application; Figure 5 Shown in is a bottom-view structural diagram of the frame provided by an embodiment of the present application. Please refer to Figure 1-Figure 5 .

[0040] like figure 1 As shown, the present embodiment provides a bogie, comprising:

[0041] Two wheel pairs 10 are arranged oppositely, and the wheel pairs 10 are arranged under the bogie for contacting the track. Each wheel pair 10 includes an axle 11 and two wheels 12 fixed on the outer peripheral surface of the axle 1...

Embodiment 2

[0062] This embodiment provides a rail engineering vehicle, including a vehicle body and the bogie described in Embodiment 1 above, and the vehicle body is arranged on the bogie.

[0063] The rail engineering vehicle of this embodiment is suitable for running on a track with a small limit because it adopts the bogie described in the first embodiment above.

Abstract

The embodiment of the invention provides a bogie and a rail engineering vehicle. The bogie comprises two wheel sets, a framework and two power devices, wherein the two wheel sets are oppositely arranged, and each wheel set comprises an axle and two wheels fixed to the two sides of the axle; each wheel set is provided with two axle boxes, and the two axle boxes are arranged on the axle and locatedbetween the two wheels; the framework comprises two side beams arranged oppositely and a cross beam connected with the two side beams, and the side beams are perpendicular to the axle and connected tothe axle boxes; the two power devices are respectively used for driving the two wheel sets to move, and are symmetrically arranged relative to the center of the bogie; the power device comprises a traction motor, a transmission mechanism and a gear box, the traction motor is arranged on the framework and connected with aninput end of the gear box through the transmission mechanism, and an outputend of the gear box is connected with the axle. The embodiment of the invention is beneficial to reducing the size of the bogie, so that the bogie is enabled to be suitable for running on a rail witha smaller limit.

Description

technical field [0001] The present application relates to rail vehicle manufacturing technology, in particular to a bogie and a rail engineering vehicle. Background technique [0002] The bogie is arranged between the car body and the track, and is one of the most important components on the track engineering vehicle. The main functions of the bogie are: supporting the car body, bearing and transmitting various loads and forces from the car body to the wheels or from the wheel rail to the car body; ensuring the safe operation of the vehicle, and being able to flexibly run along the straight line and Pass the curve smoothly; ease the interaction between the vehicle and the wheel rail, reduce vibration and shock, and improve the stability and safety of the vehicle. [0003] In the scheme of the related art, the rail engineering vehicle generally adopts the axle box external bogie. The axle box external bogie includes components such as wheel sets, axle boxes, frames, and pow...
