Description
Technical field
The utility model is related to a kind of walking-replacing tools, more particularly to a kind of scheduled bus of wheel shaft spring-compressed damping.
Background technology
With urban transportation is more and more crowded and vehicle exhaust discharge quantity it is increasing, people increasingly tend to
Use the light and environmentally friendly vehicles.Many advantages, such as scheduled bus is easy to carry, environmentally friendly due to its, is increasingly becoming people's short distance
The preferred walking-replacing tool of trip.
Simultaneously as the improvement of people's living standards, the tempo increase of work and life, a line city especially it is fast
Rhythm is lived, and in order to adapt to allegro life, people can use scheduled bus as walking-replacing tool.
Present scheduled bus has that damping is poor mostly, not bad if it is the road surface in flat-satin, if
Slightly a little concave-convex road surfaces that rise and fall, rigid collision makes people very bad using the experience of balance car, or even there are security risks；It is special
Other, the type of foot control balance car, the balance control of itself keeps balance control mainly by foot, when appearance is significantly vibrated
When, it is likely that the problem of causing danger since damping is insufficient.Certainly, in light of this situation, some scheduled buses carry out now
Improvement in terms of damping, for example, patent No. CN201520567971.4 a kind of cross-country balance car with shock mitigation system, wherein
The balance car disclosed, including inclosed body, two wheels, direction control lever and controller, the car body include upper surface, side
Wall and lower surface, there are two foot pedal, the wheel includes wheel hub, tire and wheel shaft for setting on upper surface, peace in the wheel hub
Equipped with wheel hub motor, the direction control lever top is equipped with handlebar, and shock mitigation system is equipped in the car body.But program master
If the case where being used for cross-country demand, needing damping once in a while with city be not consistent, it is desirable that it is also relatively high, it is expensive.
It should be noted that above to the introduction of technical background be intended merely to it is convenient to the technical solution of the application carry out it is clear,
Complete explanation, and facilitate the understanding of those skilled in the art and illustrate.Cannot merely because these schemes the application's
Background technology part is expounded and thinks that above-mentioned technical proposal is known to those skilled in the art.
Utility model content
In view of the drawbacks described above of the prior art, the technical problem to be solved by the utility model is to provide one kind to subtract
The scheduled bus of the wheel shaft spring-compressed damping of shake.
To achieve the above object, the utility model provides a kind of scheduled bus of wheel shaft spring-compressed damping, including：
Commute vehicle main body；
Wheel group, including wheel shaft and wheel are arranged at the both ends of the commuting vehicle main body；
It is provided with spring between the wheel shaft and commuting vehicle main body；
There are one the limited posts for limiting the spring, the commuting vehicle main body to be correspondingly arranged on for setting on the wheel shaft
Limiting slot, the spring are arranged between the limited post and limiting slot；
The axis hole for being provided at both ends with size and being more than the wheel shaft of the commuting vehicle main body, the axis hole is in wheel shaft far from vehicle
The rotary shaft hole of wheel shaft is provided perpendicular on the corresponding side wall in one end of wheel, the wheel shaft is connected to the rotation by rotary shaft
Shaft hole；
The spring is arranged between the rotary shaft hole and wheel.
Further, the limited post for limit spring is provided on the wheel shaft, the commuting vehicle main body corresponds to
It is provided with limiting slot, the spring is arranged between the limited post and limiting slot；
The slot bottom of the limiting slot is deeper than the hole face of the axis hole, and slot bottom is provided with slot column, for limiting the spring.
In the present solution, the limited post and limiting slot fix the spring for limiting, and the spring can be guided mainly to play a role
In vertical direction, avoid both sides telescopic spring direction uneven, to occur that one side damping is good and the situation of another side damping difference is sent out
It is raw；And the slot bottom of the limiting slot is deeper than the hole face of axis hole, then is to ensure that wheel shaft has enough overturning spaces, can reach without
Limitation beyond shaft bore surface, and the slot column can then coordinate the flexible work of limited post, limiting slot preferably guide springs.
Further, the limited post for limit spring is provided on the wheel shaft, the commuting vehicle main body corresponds to
It is provided with limiting slot, the spring is arranged between the limited post and limiting slot；
The slot bottom of the limiting slot is deeper than the hole face of the axis hole, and slot bottom corresponds to the limited post setting there are one be deeper than
The slot of slot bottom, for avoiding the limited post.In the present solution, the limited post and limiting slot fix the spring for limiting,
And the spring can be guided mainly to play a role in vertical direction, avoid both sides telescopic spring direction uneven, to occur one
Side damping is good and the situation of another side damping difference occurs；And the slot bottom of the limiting slot is deeper than the hole face of axis hole, then is to ensure wheel shaft
There are enough overturning spaces, also, the slot then can be used in avoiding the limited post so that the limited post is reaching topmost
When, under the premise of not further increasing axis hole size, the telescopic extensions of spring can be further improved in deep enough slot column,
So that scheduled bus is at the road surface by ground extremely out-of-flatness, by by a larger margin it is flexible come unload power by play than other
The better damping effect of damping device.
Further, what the limited post corresponded to wheel shaft is provided opposite to fluted, and the bottom portion of groove is provided with round logical
Hole；
Rotation is fixed with screw in the groove, and the screw passes through circular through hole, and the surface of prominent wheel shaft forms institute
State limited post.In the present solution, the screw solves the problems, such as to be difficult to be molded by applicable limited post, such mode shape on axis hole
At limited post, without worry limited post will appear dislocation, bending the problem of, ensure that spring limit and guiding effect；When
The right limited post can also be directly integrally formed or other are detachably mounted on the wheel shaft.
Further, the both ends of the commuting vehicle main body further include downwardly convex mounting portion, and the mounting portion includes rotation
Shaft mounting portion；The limiting slot is arranged between the rotary shaft mounting portion and wheel；
