Embodiment 1

[0031] like figure 2The shown pallet wheel for rail cars includes an integrally formed rim 100 and spokes 200, the rim 100 is provided with a tread 110, the tread 110 has a certain slope, and the slope is 3°; the spoke 200 is provided with The first clamping table 210 and the second clamping table 220, the first clamping table 210 is provided with a through hole 230, and the second clamping table 220 is provided with a threaded hole 240; the rim 100 and the wheel spoke 200 are formed by adding Cr , Ni, Mo, V and Nb trace alloying elements in AARM107 / M208 standard C grade steel, oxygen content below 15ppm. The wheel has a double clamping table, which can be matched with the flange on the axle, and then fixed by threaded holes and through holes 230 through bolts.

[0032] The effect of the above scheme is described. There is a correlation between the slope of the tread surface 110 and the rolling life, and as the slope increases, the rolling life decreases. As a result of te...

Embodiment 2

[0041] It is basically the same as Example 1, except that the added mass fractions of the trace alloying elements according to the total mass of the wheel are Cr: 0.18%, Ni: 0.15%, Mo: 0.05%, V: 0.01% and Nb: 0.35 %.

Embodiment 3

[0043] It is basically the same as Example 1, except that the added mass fraction of the trace alloying elements according to the total mass of the wheel is Cr: 0.25%, Ni: 0.15%, Mo: 0.10%, V: 0.04% and Nb: 0.15 %.

Abstract

The invention discloses a truck wheel for a rail car, which belongs to the technical field of wheels. The wheel is connected and fixed with the flange on the axle, and includes an integrally formed rim and spokes. The rim is provided with a tread, and the tread has a certain slope of 3°; the spokes are provided with a first clamping platform and The second card platform, the first card platform is provided with a first through hole, and the second card platform is provided with a through hole; the rim and the spoke are alloyed by adding Cr, N, Mo, V and Nb Element's AARM107 / M208 grade C steel. The wheel structure of the present invention is different from ordinary wheels, and the difference lies in the assembly method. The ordinary wheel press-fit requires special wheel pair press-fit equipment, and the wheel adopts the mode of clearance fit and bolt connection.

Description

technical field [0001] The invention belongs to the technical field of wheels, and more particularly, relates to a pallet wheel for rail vehicles. Background technique [0002] The rail wheel train of the rail dual-purpose vehicle is the main moving device for the vehicle to move on the rail, so the design of the rail wheel should meet the size, strength and shock absorption requirements of the locomotive when it runs on the rail. On the other hand, when the vehicle is running on the road, the track wheel must be stowed away and fixed, so as not to affect the normal operation of the rubber wheel. Specifically, the design of the track wheel has the following two points: the dimensions of each component of the track wheel system meet the requirements of track running and meet the strength requirements; the track wheel system must have excellent shock absorption effect and be stable and reliable when running on the track. [0003] Due to the limited space at the bottom of the ...
