Embodiment 1

[0020] Such as figure 1 and image 3 As shown, the present embodiment is an integrated simplified structure, including two pairs of wheelsets 3, a framework including side beams 1 and cross beams 7, axle boxes 2 and secondary suspensions.

[0021] The bogie frame is an H-shaped frame, a side beam 1 is respectively arranged on both sides of the beam 7, and axle boxes 2 are installed at both ends of the axles of the wheel set 3. The two ends of the side beam 1 match the shape of the installation surface of the axle box 2, and are directly suspended on the axle box 2. There is no traditional primary suspension including a spring unit between the two, and a traditional axle box guide frame is used between the two The positioning method of the target.

[0022] The frame side beam 1 of the bogie is composed of a high damping material. Specifically, in this embodiment, it is composed of a Fe-Mn based composite damping alloy. This material has high strength, a tensile strength highe...

Embodiment 2

[0025] as attached figure 2 and Figure 4 As shown, the present embodiment is a combined simplified structure. The main difference is that the frame side beam 1 of embodiment 1 is an elastic beam as a whole, while the side beam 1 of this embodiment consists of two sections of flexible beam sections 5 and The three rigid beam sections 8 are fixedly connected, and carbon fiber material is used. This material itself has the characteristics of high flexural and shear strength, light weight, strong elastic deformation and recovery ability. Both ends of the flexible beam section 5 are connecting seats, and the middle is also a sheet structure. The connecting seats at both ends of the flexible beam section 5 are respectively connected with different rigid beam sections 8 to form the entire side beam 1 . The elasticity of the side beam 1 mainly comes from the elastic deformation of the flexible beam section 5 itself. An elastic damping layer 6 is installed at both ends of the side...

Abstract

The invention provides a bogie with a simple structure, and relates to the technical field of car bogies. The bogie with the simple structure includes a framework which is composed of side beams and across beam and a wheel set and an axle box, the side beams of two sides of the framework of the bogie are of an integrated or combined bow-shaped structure, and two end bow heads are of a horizontally placed F-shaped structure; two ends of the cross beam are separately fixed with the inner side of the middle sections of the side beams, the middle of the side beams is of a flat plate-shaped structure, and the side beams are provided with air springs; the combined side beams are formed by the connection of flexible beam sections and solid beam sections, and bow heads of the two ends of the beamsections are provided with F-shaped openings which face downward; the bow backs of the bow-shaped structural side beams face downward, and grooves which are identical with the shape of the mounting face of the axle box are formed in the position, facing downward, of the openings of the horizontally arranged F-shaped structure; and the flexible beam sections of the combines side beams are of a flat plate-shaped structure. The bogie with the simple structure is mainly used for being matched with rail cars.

Description

technical field [0001] The invention relates to the technical field of rail vehicle bogies. [0002] technical background [0003] The existing bogies are basically H-shaped welded frames. On the one hand, rail vehicle bogies are an important part of rolling stock, and they play important roles in carrying, driving, damping, guiding and braking. The existing bogie mainly includes two suspensions, which are divided into primary suspension and secondary suspension. The combination of the two can ensure the vehicle's motion stability and curve passing ability, reduce the unsprung mass and reduce the force on the line And so on. In the two-series suspension, the function of the first-series suspension is mainly to suppress the vibration of the car body, ease the interaction between the wheel and the rail, and reduce the wheel-rail noise. The side beams of the H-shaped welded frame are generally box-shaped rigid beams welded by multiple steel plates. Rigid welded frames are inf...
