Embodiment 1

[0039] figure 1 Shown in is a structural diagram of a bogie provided by an embodiment of the present application; figure 2 shown in figure 1 side view; image 3 shown in figure 1 bottom view of ; please refer to Figure 1-Figure 3 .

[0040] This embodiment provides a bogie including at least two wheel sets 10 , a frame 20 , a primary tie spring 40 , a secondary tie spring 50 and a traction device 60 .

[0041] Wherein, the wheelset 10 is arranged below the frame 20 for contacting the track. The number of wheel pairs 10 can be set as required, such as two, three and so on. Each wheel set 10 includes an axle 11 and two wheels 12 fixed on the outer peripheral surface of the axle 11. The wheels 12 are the direct parts of the bogie in contact with the track. The axle 11 is used to transmit the power of the driving device to the wheels 12, so as to The wheels 12 are driven to move along the track. The axle 11 protrudes beyond the two wheels 12 , and the wheel-set axle boxe...

Embodiment 2

[0082] This embodiment provides a rail vehicle, including a vehicle body and the bogie as described in the first embodiment above, and the vehicle body is arranged on the bogie.

[0083] Since the rail vehicle in this embodiment adopts the bogie described in the first embodiment, the noise is small, which is beneficial to improve the riding experience of passengers.

Abstract

A bogie and a rail vehicle are provided in the embodiments of the present application. The bogie includes a frame, the frame includes two side beams arranged opposite to each other and a beam connecting the two side beams, and the beam includes a main body for connecting a traction device and a As for the connection part hinged with the side beam, the connection part is arranged at both ends of the main body part, and the width of the connection part is gradually reduced in the direction away from the main body part; one end of the connection part away from the main body part is movably connected with the side beam. In the present application, the two ends of the beam are movably connected to the two side beams, so that a certain displacement can be generated between the beam and the side beams, so that the frame is flexible, and the frame itself can absorb a part of the twisting energy, so as to improve the anti-twisting ability of the bogie, It is conducive to the safe, high-speed and flexible passage of rail vehicles through uneven road surfaces or curved road surfaces, and improves the safety of rail vehicles.

Description

technical field [0001] The present application relates to the technical field of rail vehicles, and in particular, to a bogie and a rail 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 rail 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, flexibly running along straight lines and Pass the curve smoothly; ease the interaction between the vehicle and the wheel-rail, reduce vibration and shock, and improve the running stability and safety of the vehicle. According to whether there is a power device, the bogie can be divided into a power bogie and a non-power bogie. [0003] The frame is the core component of the bogie, and plays an important role in connecting various functional components, be...
