Abstract
The utility model discloses a balance car wheel, including tire and wheel hub, its characterized in that: be provided with the cusp step on wheel hub's the fitting surface, the width that the cusp step is close to wheel hub one side is less than the width of keeping away from wheel hub one side, inner surface of tyre sets up in the recess with cusp step looks adaptation, the utility model discloses a mating surface transmission power of cusp step and recess no longer need keep great transmission frictional force between tire and the wheel hub, the size of tire can be done greatlyyer, and on wheel hub was installed more easily to the tire, the tensile degree of installation back tire was lower simultaneously, has avoided long -time and has been in excessive tensile state, has improved the practical life of tire and the security of going.
Description
Technical field
This utility model is related to balance car accessory technical field, a kind of balance car of specific design no inflate in empty wheel.
Background technology
Also known as body-sensing car, thinking car etc., its operation principles is mainly built upon a kind of dynamic stability that is referred to as to balance car
In ultimate principle；The Main Function of balance car wheel hub is to connect to support tire, transmits torque by motor in hub, drives tire to connect
Ground rotation, is advanced by the friction and then drive balance car on tire and ground or retreats.Existing leveling wheel hub structure is mostly
One is that bright finish is cylindrical with the integrally formed hub body of outer end cap, wheel hub with the fitting surface of tire, and motor is put in inside, then plus
One inner side end cap, in order to ensure that tire and wheel hub after assembling have sufficient frictional force, is adapted with the wheel hub of this structure
Tire diameter is necessarily less than wheel hub and installs cylinder external diameter 5-8mm；During mounting tyre, need tire using special stamping machine
Pour on wheel hub, then lock inner side end cap.
Tire after this kind of wheel hub assembling is constantly in excessive tensile state, and through travelling after a while, tire can be gradually
Lose due elasticity, tire inner ring also tapers into the constraint of wheel hub, thus causing tire to skid with wheel hub, can not be effective
Transmission power, enters you and produces tire knocking over.Tire is in excessive tensile state for a long time simultaneously, and its joint also easily splits；Draw
Stretch rear carcass profile uneven, easily produce tire runout and beat, impact is produced on the stationarity travelling.
Publication No. CN203681141U China utility model discloses a kind of new supporting bridge on July 2nd, 2014
Wheel hub structure, including supporting bridge hub body, hub periphery is staircase structural model, and the step number of hub periphery is 8-12.
Content of the invention
Low for efficiency of assembling present in prior art, the short defect of Life of Tyre, the utility model discloses
A kind of balance car wheel, can reach raising tire and the efficiency of assembling of wheel hub and the service life of tire using this utility model
Purpose.
A kind of balance car no inflate in empty wheel, including tire and wheel hub it is characterised in that：On described wheel hub fitting surface
It is provided with multiple dentiform steps；The width near wheel hub side for the described dentiform steps is less than the width away from wheel hub side；Described
Tire inner surface is provided with the groove being adapted with wheel hub dentiform steps.
Described dentiform steps edge is provided with arc-shaped transitional surface.
Described dentiform steps are located on the same circumference of fitting surface.
Compared with prior art, this utility model has the advantages that：
1st, it is provided with multiple dentiform steps on balance car wheel hub described in the utility model, dentiform steps are near wheel hub side
Width be less than away from wheel hub side width, be provided with the groove being adapted with wheel hub dentiform steps inside tire, wheel hub lead to
The field of conjugate action crossing dentiform steps with groove transmits power, revolutionizes the mode that traditional dependence frictional force transmits power, wheel
Tire does not need for the enough frictional force of guarantee and reduces size, reduces the assembly difficulty of tire and wheel hub, improves efficiency of assembling；
The tensile strength of increased in size rear tyre reduces simultaneously, improves the service life of tire.
2nd, dentiform steps edge described in the utility model is provided with arc-shaped transitional surface, can reduce dentiform steps stress
Concentration degree, is also avoided that assembled scratches tire simultaneously.
3rd, dentiform steps described in the utility model are located on the same circumference of fitting surface, facilitate between tire and wheel hub
Assembling, reduces the assembly difficulty of tire and wheel hub, improves the efficiency of assembling.

Specific embodiment
By specific embodiment, this utility model will be described further below：
Embodiment 1
The present embodiment, as most preferred embodiment of the present utility model, it discloses empty car during a kind of balance car is no inflated
Wheel, including tire 1 and wheel hub 2, tire 1 is installed on wheel hub 2, and wheel hub 2 two sides are provided with outer end cap 5 and inner end cap 6, described
Outer end cap 5 and inner end cap 6 are connected on wheel hub 2 by bolt 7, and outer end cap 5 and inner end cap 6 are mounted on bearing 8, inner end cap 6
On be also equipped with axle envelope 9, described axle envelope 9 and bearing 6 are arranged concentrically；Multiple dentation platforms are provided with the fitting surface of described wheel hub 2
Rank 3, the width near wheel hub 2 side for the described dentiform steps 3 is less than away from wheel hub 2 side.
The edge of described dentiform steps 3 is provided with arc-shaped transitional surface, a diameter of 2-5mm of circular arc.
Described dentiform steps 3 are located on the same circumference of fitting surface.
Operation principle of the present utility model：The field of conjugate action passing through between wheel hub and tire between dentiform steps and groove is realized
Transmission, relies on compared with the mode of frictional force realization transmission between wheel hub and tire, tire of the present utility model with conventional tire
Larger frictional force need not be kept and wheel hub between, the increasing that the size of tire can be suitable, reduce between tire and wheel hub
Assembly difficulty, thus improving the efficiency of assembling, simultaneously larger tire size then makes post-tensioning on being assembled to wheel hub for the tire
Expanding degree is less, it is to avoid tire is in the possible permanent damage under excessive tensile state to tire for a long time, after long-time use
Will not follow the string, the joint of tire is not easy to rupture, and substantially increases service life and the safety of tire.
This utility model has the advantages that efficiency of assembling is high, long service life and safe.
