Embodiment 1

[0082] This embodiment provides a bogie, which can be applied to a rail vehicle. The rail vehicle can be a diesel locomotive or an electric locomotive, and can be a multiple train, subway, light rail, or tram.

[0083] figure 1 It is a schematic structural diagram of the bogie provided in Embodiment 1 of the present application, figure 2 A top view of the bogie provided in Embodiment 1 of the present application. like figure 1 and figure 2 As shown, the bogie provided in this embodiment includes: wheel sets, side beams, axle boxes, connecting seats, traction devices and the like.

[0084] Wherein, there are two wheelsets arranged side by side. The wheel set includes: an axle 11 and wheels 12, and the number of the wheels 12 is two, which are arranged symmetrically on the axle. The axle 11 is connected with the wheels 12, and the rotation of the axle 11 can drive the wheels 12 to rotate synchronously. There are two axle boxes 13 , which are symmetrically arranged on the...

Embodiment 2

[0093] This embodiment provides a specific implementation of the bogie:

[0094] like figure 1 and figure 2 As shown, the bogie provided by this embodiment includes two mutually independent side beams 2, the two side beams are parallel and extend along the longitudinal direction. The axle box 13 is located on the inner side of the wheel 12 and is close to the wheel 12 . The end of the side beam 2 is connected with the axle box 13 through the primary suspension device 7, and the primary suspension device 7 plays the role of supporting the side beam 2 and buffering the vertical force.

[0095] The middle part of each side beam 2 is provided with a connecting base 3 , and the top of the connecting base 3 is provided with a secondary suspension device 8 . The top of the secondary suspension device 8 is connected with the vehicle body, and is used for supporting the vehicle body and buffering the vertical force.

[0096] The traction device 4 is connected between the two conne...

Embodiment 3

[0233] This embodiment provides a rail vehicle, which can adopt the bogie provided by any one of the above embodiments. The bogie provided in this embodiment adopts the above-mentioned bogie. By adopting two independent side beams across the two sets of wheels, the two side beams are parallel to each other, and the ends of the side beams are located above the axle box. Support; a connection seat is arranged in the middle of each side beam, and the traction device is connected between the two connection seats to provide traction or braking force to the vehicle body. Since the two side beams are independent, smaller in size and lighter in weight, the manufacturing process is less difficult. In the subsequent assembly process with other components, the hoisting process is relatively light, which can simplify the alignment and alignment operation.

Abstract

An embodiment of the present application provides a bogie and a rail vehicle, wherein the bogie includes: two sets of wheels arranged side by side; the wheels include an axle and two wheels symmetrically arranged on the axle; For the upper two side beams; the two side beams are parallel to each other; the side beams include: a first beam plate, a second beam plate located above the first beam plate and having a preset distance from the first beam plate, And a beam plate buffer arranged between the middle part of the first beam plate and the middle part of the second beam plate; the axle box is arranged on the wheel set and is located below the side beam for supporting the side beam; two connecting seats, each It is arranged in the middle of a side beam; the traction device is connected between the two connection seats; the traction device is also used to connect with the vehicle body. The bogie and the rail vehicle provided by the embodiments of the present application can reduce the difficulty of assembling the bogie.

Description

technical field [0001] The present application relates to rail vehicle running technology, in particular to a bogie and a rail vehicle. Background technique [0002] Rail vehicles are an important transportation link connecting cities, and have gradually become the main means of transportation in cities. Rail vehicles are also the main carrier for cargo transportation. A rail vehicle mainly includes: a car body and a bogie arranged under the car body. The bogie is used to carry the car body and realize the running and steering functions. [0003] The traditional bogie mainly includes: frame, wheelset, traction device, braking device and buffer device, etc., and the power bogie also includes the driving device. Among them, the frame is the main skeleton of the bogie, and the other components are associated with the frame. The frame usually consists of two parallel side beams and a cross beam connected between the middle of the two side beams to form an "H" structure. The f...
