Problems solved by technology
However, when the existing trains go abroad, there are different rail gauges between countries. The trains cannot be used directly.
The patent for universal axles with different gauges of trains separates the load-bearing and guiding functions of the wheels, making the bridge structure complex

Embodiment Construction
[0010] exist figure 1 Among them, the train wheel 3 and the axle shaft 8 are clearance fit, and the wheel 3 can move axially on the axle shaft 8. Limit stud 12 is enclosed within axle 8 shaft end side frame 1 support bearing inboards, is fixed on the axle with set screw 13, and limit nut 11 is screwed on the limit stud 12, locks with locking bolt 2. Locating stud 4 and 7, one is left thread, and the other is right thread, is enclosed within on the axle 8, and wheel 3 inner side, withstands wheel. The positioning studs 4 and 7 are limited by the pin 10, relative to the shaft 8, they only move axially and do not rotate. Locating nut 6 is screwed on two locating studs 4 and 7 symmetrically, corresponds with locating studs 4 and 7 with left and right spiral threads.
[0011] exist figure 2 Among them, the rails a and b of different gauges are connected by straight line and symmetrical oblique angle, and from the point of contact with the small gauge rail a to the length of the...

The utility model relates to a movable train wheel, which changes the interference fit between the train wheel and the axle into a clearance fit, and positions the wheel on the axle during the running of the train. The rails of different gauges are connected with straight lines, equal heights, symmetrical oblique angles, and guide grooves are provided from the point of contact with the small gauge rails to the length of the train entering the large gauge rails. When the train drives to the large gauge rail and stops, adjust the limit nut outward until the wheel enters the large gauge rail, just to withstand the wheel, start the train and run slowly until the train completely enters the large gauge rail and stops. Adjust the positioning stud to tighten the top wheel, and the train enters the large-gauge steel rail and runs normally. When the train drives to the small-gauge rail and stops, adjust the positioning stud to move inward until the wheel enters the small-gauge rail, just to withstand the wheel, start the train to run slowly, and stop after all the train enters the small-gauge rail. Adjust the limit nut to tightly press the wheel, and the train will enter the small gauge rail and run normally.
Description
technical field [0001] What the present invention relates to is a kind of train wheel, exactly is the train wheel that can move axially on the shaft and adapts to the rail gauge of different countries. Background technique [0002] In order to transport goods to all parts of the world quickly and with low trade costs, direct transnational train transportation is needed. And the existing train goes abroad, and the rail gauge between countries is different, and the train cannot be used directly, and needs to be unloaded and then loaded on to another country's train to run, wasting a lot of manpower, material resources and time. And the different gauge universal axle patent of train is to separate the bearing and guiding function of the wheel, which makes the axle structure complex. Contents of the invention [0003] In order to avoid the occurrence of the above situation, the present invention provides a wheel with inseparable bearing and guiding functions, which can direct...
