Abstract
The invention discloses a kind of balance car wheel, including tire and wheel hub, it is characterised in that：Dentiform steps are provided with the fitting surface of the wheel hub, width of the dentiform steps close to wheel hub side is less than the width away from wheel hub side, the tire inner surface is arranged at the groove being adapted with dentiform steps, the present invention passes through dentiform steps and the field of conjugate action transfer motion power of groove, no longer need to keep larger gearing friction power between tire and wheel hub, the size of tire can do more, tire is more easily installed on wheel hub, the level of stretch for installing rear tyre simultaneously is lower, avoid and be in excessive tensile state for a long time, improve the physical life of tire and the security of traveling.
Description
Technical field
The present invention relates to balance car accessory technical field, and a kind of balance car of specific design is without empty wheel in inflation.
Background technology
Balance car is also known as body-sensing car, thinking car etc., and its operation principles is mainly built upon a kind of dynamic stability that is referred to as
In general principle；The main function of balance car wheel hub is connection support tire, transmits torque by motor in hub, drives tire to connect
Ground rotates, and drives balance car to advance or retreat by the friction on tire and ground.Existing leveling wheel hub structure is mostly
The fitting surface of one and the integrally formed hub body of outer end cap, wheel hub and tire is smooth surface cylinder, and motor is put in inside, then adds
One inner side end cap, in order to ensure that the tire after assembling and wheel hub have sufficient frictional force, is adapted with the wheel hub of this structure
Tire diameter is necessarily less than wheel hub installation cylinder external diameter 5-8mm；When tire is installed, special stamping machine is needed to use by tire
Pour on wheel hub, then lock inner side end cap.
Tire after such a wheel hub assembling is constantly in excessive tensile state, and through travelling after a while, tire can be gradually
Due elasticity is lost, constraint of the tire inner ring to wheel hub also tapers into, can not be effective so as to cause tire to be skidded with wheel hub
Passing power, enter you and produce tire knocking over.Tire is in excessive tensile state for a long time simultaneously, and its joint also easily splits；Draw
It is uneven to stretch rear carcass profile, easily produces tire runout and bounce, the stationarity of traveling is had an impact.
Publication No. CN203681141U China's utility models disclosed a kind of new supporting bridge on July 2nd, 2014
Wheel hub structure, including supporting bridge hub body, hub periphery are staircase structural model, and the step number of hub periphery is 8-12.
The content of the invention
Low for efficiency of assembling present in prior art, the defects of Life of Tyre is short, the invention discloses one kind
Balance car wheel, the purpose of the service life of the efficiency of assembling for improving tire and wheel hub and tire can be reached using the present invention.
A kind of balance car is without empty wheel in inflation, including tire and wheel hub, it is characterised in that：On the wheel hub fitting surface
It is provided with multiple dentiform steps；Width of the dentiform steps close to wheel hub side is less than the width away from wheel hub side；It is described
Tire inner surface is provided with the groove being adapted with wheel hub dentiform steps.
The dentiform steps edge is provided with arc-shaped transitional surface.
The dentiform steps are located on the same circumference of fitting surface.
Compared with prior art, the invention has the advantages that：
1st, multiple dentiform steps are provided with balance car wheel hub of the present invention, width of the dentiform steps close to wheel hub side is small
The groove being adapted with wheel hub dentiform steps is provided with the inside of the width away from wheel hub side, tire, wheel hub passes through dentation platform
Rank and the field of conjugate action passing power of groove, revolutionize traditional mode by frictional force passing power, and tire need not
Frictional force to ensure enough reduces size, reduces the assembly difficulty of tire and wheel hub, improves efficiency of assembling；Increase simultaneously
The tensile strength of size rear tyre reduces, and improves the service life of tire.
2nd, dentiform steps edge of the present invention is provided with arc-shaped transitional surface, can reduce the concentration of dentiform steps stress
Degree, while also it is avoided that assembled scratches tire.
3rd, dentiform steps of the present invention are located on the same circumference of fitting surface, facilitate the dress between tire and wheel hub
Match somebody with somebody, reduce the assembly difficulty of tire and wheel hub, improve the efficiency of assembling.

Embodiment
Below will the present invention will be further described by embodiment：
Embodiment 1
The present embodiment is as highly preferred embodiment of the present invention, it discloses a kind of balance car without empty wheel in inflation, including wheel
Tire 1 and wheel hub 2, tire 1 are installed on wheel hub 2, and the two sides of wheel hub 2 are provided with outer end cap 5 and inner end cap 6, the He of outer end cap 5
Inner end cap 6 is connected on wheel hub 2 by bolt 7, and outer end cap 5 and inner end cap 6 are mounted on bearing 8, are also equipped with inner end cap 6
Axle envelope 9, the axle envelope 9 and bearing 6 are arranged concentrically；Multiple dentiform steps 3, the tooth are provided with the fitting surface of the wheel hub 2
Width of the shape step 3 close to the side of wheel hub 2 is less than away from the side of wheel hub 2.
The edge of the dentiform steps 3 is provided with arc-shaped transitional surface, a diameter of 2-5mm of circular arc.
The dentiform steps 3 are located on the same circumference of fitting surface.
The operation principle of the present invention：Realized and passed by the field of conjugate action between dentiform steps and groove between wheel hub and tire
It is dynamic, compared with conventional tire realizes the mode of transmission by the frictional force between wheel hub and tire, tire and wheel hub of the invention
Between need not keep larger frictional force, the increasing that the size of tire can be appropriate, reduce the assembling between tire and wheel hub
Difficulty, so as to improve the efficiency of assembling, while larger tire size then make tire on wheel hub is assembled to after stretch range
It is smaller, avoid tire from being in for a long time under excessive tensile state to the possible permanent damage of tire, will not also be lost after long-time use
Elasticity is gone, the joint of tire is not easy to be broken, and substantially increases the service life and security of tire.
The present invention has the advantages that efficiency of assembling is high, service life is long and safe.
