Problems solved by technology

However, when the roadbed collapses, the wind is strong, the track is deformed or the turning speed is fast, and the centrifugal force is large, the train is prone to rollover, resulting in derailment accidents.

Embodiment Construction

[0022] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0023] Such as figure 1 As shown, the train wheel of the present invention includes a rotating shaft 5, both ends of the rotating shaft 5 are equipped with wheels 3, the wheel 3 is provided with an outer rim 4, and the outer rim 4 on one wheel 3 is located on the end face of the wheel 3 away from the other wheel 3. on.

[0024] When the train wheel of the present invention is used on a train, the connection mode of the car 4 and the train wheel is the same as the connection mode of the train wheel with inner rim and the car 4 in the prior art, such as figure 2 ; The train wheels of the present invention are pressed on the rail 5, and the outer rims 4 on the two wheels 3 are located on the outside of the two steel rails.

[0025] The rim of the wheel 3 of the train wheel of the present invention is on the outside of the wheel. When the carriage 4 is inclined to on...

Abstract

The invention discloses a train wheel and a railway turnout matched with the train wheel. The train wheel comprises a rotating shaft, wheels are installed at two ends of the rotating shaft, outer wheel flanges are arranged on the wheels, and the outer wheel flange on one wheel is located on an end surface, deviating from the other wheel, of the wheel. The railway turnout comprises a turnout switchrail and a movable point rail, the turnout switch rail is located at a bifurcation position of two intersecting rails, two steel rails in the turnout switch rail are located on the outer sides of thetwo steel rails located on the outermost side in the two intersecting rails respectively, and a tip of the movable point rail faces a direction deviating from the turnout switch rail. A friction force and a stress which are generated by an outer wheel flange structure of the train wheel and hinder inclination are located on the other side different from an inclination or rollover fulcrum, the armof force of a friction force moment and a stress moment for resisting rollover is larger, the friction force moment and the stress moment are larger too, and a rollover resisting capacity is higher.

Description

Technical field [0001] The invention belongs to the technical field of railway locomotives, and relates to a train wheel; the invention also relates to a railway turnout adapted to the train wheel. Background technique [0002] The train wheels are pressed on the rails to transmit the gravity of the train. On the inner side of the train wheel, there is a disk with a larger radius than the wheel—the rim. The rim makes the wheels "stick" on the track, ensuring that the wheels are always running on the track, and are used to control the direction of the train. In addition, when the train turns, the height difference between the inner and outer rails will form the centripetal force of the train turning. If the speed of the train is fast when turning, the rim of the wheel on the side farther from the turning center will contact the rail, which will exert pressure on the rail. The rim also has a reaction force directed to the center of the turning circle, which is a component of the ...
