Located lateral wheel group 300 includes locating wheel 310 and return wheel 320.In same railcar 10, two locating wheels
310 are used to be connected with the same side roll of track, and two return wheels 320 are then used for and track relative to two locating wheels 310
Opposite side is in rolling contact.Wherein, locating wheel 310 is fixedly connected on car body 100, and return wheel 320 is resiliently attached to car body 100, and
And the distance between locating wheel 310 and return wheel 320 are less than or equal to the distance between of laterally opposite both sides of track, that is, position
The distance between wheel 310 and the distance between return wheel 320 of laterally opposite both sides of track are adapted.In the present embodiment,
Locating wheel 310 and return wheel 320 are single-wheel, i.e., same group of located lateral wheel group 300 includes a locating wheel 310 and one
Return wheel 320.It should be appreciated that in other embodiments, the locating wheel 310 in same group of located lateral wheel group 300 can also be
Multiple, the outside common tangent of the wheel rim of multiple locating wheels 310 is parallel all the time with track side surfaces, and is contacted simultaneously with track, and its
The distance between adjacent locating wheel 310 of middle each two should be greater than the width of the seam of track.In addition, in other embodiments,
Multiple return wheels 320 can also be included in same group of located lateral wheel group 300, multiple return wheels 320 carry to locating wheel 310 simultaneously
Ammunition feed power so that locating wheel 310 keeps contacting with track side.
It should be noted that the distance of the of laterally opposite both sides of above-mentioned track refers to that a track is laterally upper relative
The distance between two sides.
In the present embodiment, two located lateral wheel groups 300 are used to be connected with same track, that is, cause two locating wheels
310 and two return wheels 320 be held on same track so that locating wheel 310 can be fixed by the elastic force of return wheel 320
The side that position wheel 310 can be bonded track all the time, ensure railcar 10 along straight-line travelling, avoid the occurrence of the situation of serpentine locomotion.
Further, in same railcar 10, direction where the line of two return wheels 320 is first direction, same
Direction where locating wheel 310 and the line of return wheel 320 in group located lateral wheel group 300 is second direction.Wherein, return wheel
320 rotary shafts are be hinged with car body 100, and return wheel 320 on first direction with car body 100 in being rigidly connected, and return wheel 320 is in second
On direction with the elastic connection of car body 100.That is, return wheel 320 upper in a second direction can produce elastic deformation so that return wheel 320
Optionally remotely located wheel 310 or close locating wheel 310.
In the present embodiment, because the distance between locating wheel 310 and return wheel 320 are less than track laterally upper opposite sides
Distance so that located lateral wheel group 300 can make when being connected to track return wheel 320 it is remotely located wheel 310 skew certain distances,
I.e. so that return wheel 320 has the trend moved towards locating wheel 310 so that locating wheel 310 and the gripper rail of return wheel 320,
Ensure that locating wheel 310 is in rolling contact with track all the time, ensure that railcar 10 does not produce serpentine locomotion when advancing.
Locating wheel 310 can be adjusted relative to the height under the rail plane of track, and locating wheel 310 connects with track
Contact can be any given position.
It should be noted that the above-mentioned first direction being previously mentioned is the direction of track extension, i.e. railcar 10 is connected to rail
Direct of travel during road.Second direction is the transverse direction of the above-mentioned track perpendicular to direct of travel being previously mentioned.

Connection and track can be rolled.Wheel 200 has the second rotary shaft 210, and wheel 200 can rotate around the second rotary shaft 210, with
It can roll and connect with track.Wherein, the first rotary shaft 311 causes locating wheel 310 and wheel perpendicular to the second rotary shaft 210
200 each complete respective work in the case where not producing interference mutually.Also, locating wheel 310 can be caused positioned at transverse direction
Plane so that located lateral effect is more preferable caused by locating wheel 310.
Further, the thickness of locating wheel 310 is gradually increased by outer rim to the axle center of locating wheel 310 of locating wheel 310.
In the present embodiment, locating wheel 310 is " V " font from wheel rim to the section of wheel axis center, i.e., locating wheel 310 passes through the first rotary shaft
311 and be " V " font positioned at the section of the first rotary shaft 311 wherein side.The thickness of return wheel 320 is by the outer of return wheel 320
Edge to the axle center of return wheel 320 gradually increases, and in the present embodiment, the section of return wheel 320 is " V " font, i.e. return wheel 320
The section of section by axis and the wherein side positioned at axis is " V " font.To ensure that track side surfaces have greasy dirt and soil
When, side plane of the locating wheel 310 still with track in located lateral wheel group 300 is in close contact.It should be appreciated that at other
In embodiment, return wheel 320 can also be other shapes, such as cylindricality etc..
In the present embodiment, two groups of located lateral wheel groups 300 are connected to the front and rear of the side of car body 100, with
So that the enough length of the distance between two groups of located lateral wheel groups 300, to keep the travel direction of railcar 10.
In addition, in the present embodiment, two groups of located lateral wheel groups 300 can be according to the quantity of the wheel 200 of railcar 10
Corresponding installation.
Wherein, when the quantity of wheel 200 is the even number more than 2, two groups of located lateral wheel groups 300 are connected to railcar 10
Left side or right side.I.e. two groups of located lateral wheel groups 300 can only be installed on the same side of railcar 10 simultaneously, to ensure two groups of horizontal strokes
It can be in rolling contact simultaneously with same one side track to locating wheel group 300, it is not in the situation of serpentine locomotion to ensure railcar 10.
In the present embodiment, such as Fig. 3, the quantity of wheel 200 is 4, and two groups of located lateral wheel groups 300 are connected to railcar
10 left side, certainly, two groups of located lateral wheel groups 300 can also be connected to the right side of railcar 10.
In addition, when wheel 200 is two, two groups of located lateral wheel groups 300 are connected to installing wheel 200 on car body 100
Side.
When the quantity of wheel 200 is odd number, two groups of located lateral wheel groups 300 are connected to car body 100 and install more wheel 200
Side.Wherein, it is mostly three wheels 200 using the railcar 10 of the wheel 200 of Odd number, now two groups of located laterals
