Description
Technical field
The utility model is related to solid tyre fields, and in particular to be a kind of high shock reducing non slipping type ETPU solid tyre,
It has the characteristics that damping performance is good and non-skid property is good.
Background technology
According to Baidupedia, tire refers to the circular ring shape elasticity rubber rolled in various vehicles or the ground connection mechanically assembled
Glue product, it is typically mounted on holder, can support vehicle body, buffering foreign impacts etc..Bicycle, perambulator and toy car etc.
For light non-motor vehicle, own wt is small, and the load that tire is born is small, therefore tire used belongs to a kind of low load wheel
Tire.For above-mentioned low load tire, the elasticity and portability of tire itself are to the handling particularly important of vehicle.Used in the market
Low load tire includes mainly pneumatic tire and non-inflatable tyre.Subject to damage during pneumatic tire use, for small size
Low load tire, replace more difficult, therefore pneumatic tire is rarely applied on baby carriage tires and toy tyre.Exempt from inflated wheel
Tire can to avoid pneumatic tire there are the problem of, can be widely applied to the fields such as perambulator, toy.Non-inflatable tyre includes not foaming
Solid tyre, foaming solid tyre and foaming body filled-type tire etc..
The present inventor had once applied for a kind of thermoplastic polyurethane low load tire comprising for what is directly contacted with ground
Epidermis and the inner layer inside epidermis, the hardness of the epidermis are higher than the hardness of inner layer, and the epidermis and inner layer are adopted
It is foaming-formed with TPU expanded particles.But whether how to be molded using TPU expanded particles, in wear-resisting and on-slip
It is promoted relatively limited in performance, is based on this, the applicant's hammer away regarding to the issue above has this case generation then.
Utility model content
The main purpose of the utility model is to provide a kind of high shock reducing non slipping type ETPU solid tyre, allow epidermis and
It can be preferably merged between buffer layer, and have the characteristics that damping property and non-skid property are preferable.
In order to achieve the above objectives, the solution of the utility model is：
A kind of high shock reducing non slipping type ETPU solid tyre, wherein epidermis, buffer layer and Nei Lian including being in circular ring shape
Connect layer, the epidermis and interior articulamentum are respectively coated by the outer rim side for being connected to buffer layer and inner ring side, the epidermis and interior
There are outer annular gap is exposed to for buffer layer between articulamentum, the buffer layer is by ETPU particles through vapor foaming
It forms, the epidermis and interior articulamentum are all made of TPU material injection moldings.
Further, the interior articulamentum has the covering portion being coated on outside buffer layer and the company being integrally connected with clad
Socket part is also formed with several screw connecting holes on the interconnecting piece, and each screw connecting hole penetrates through two sides of interconnecting piece
Face.
Further, several groups groove made of circular array is also formed on the epidermis, every group of groove all has
First groove and second groove, the first groove extend along the circumferential direction of epidermis, and the second groove is then with first
Angle between groove is acute angle.
With the above structure, the utility model is related to a kind of high shock reducing non slipping type ETPU solid tyre, with the prior art
It compares, the utility model at least has the advantages that：
One, the utility model forms epidermis in such a way that TPU materials (thermoplastic polyurethane elastomer) are by injection molding
Belong to identical material since both thermoplastic polyurethane elastomer and ETPU particles belong to polyurethane material with interior articulamentum
Expect classification, there is preferable blending, can to can be connected between epidermis and interior articulamentum and buffer layer whole for one
Body improves the quality of entire solid tyre.
Two, the solid tyre that the utility model is formed, epidermis is hard compared to buffer layer, and the buffer layer is compared
It is soft in epidermis, the prior art is essentially all that epidermis is soft, and the inside is hard, and practical damping effect is poor；Separately
Outside, there are annular gaps between epidermis and interior articulamentum by allowing for the utility model so that the inside articulamentum of epidermis transmits
Active force all to pass through buffer layer, it is ensured that all active forces can all obtain the cushioning effect of buffer layer.
Three, the utility model on epidermis further also by being formed with anti-skidding several groups groove, to carry significantly
The non-skid property of entire ETPU solid tyre is risen.
Description of the drawings
Fig. 1 is that the utility model is related to a kind of structural schematic diagrams of high shock reducing non slipping type ETPU solid tyre.
Fig. 2 is that the utility model is related to a kind of sectional views of high shock reducing non slipping type ETPU solid tyre.
In figure：
Epidermis -1；First groove -11；Second groove -12；

Specific implementation mode
In order to which the technical solution of the utility model is explained further, below by specific embodiment come to the utility model into
Row elaborates.
As depicted in figs. 1 and 2, be the utility model is related to a kind of high shock reducing non slipping type solid tyre, including be in
Epidermis 1, buffer layer 2 and the interior articulamentum 3 of circular ring shape.
The epidermis 1 and interior articulamentum 3 are respectively coated by the outer rim side for being connected to buffer layer 2 and inner ring side, the epidermis
There are outer annular gap 4 is exposed to for buffer layer 2 between layer 1 and interior articulamentum 3, the buffer layer 2 is by ETPU particles through water
Steam foaming forms, and the epidermis 1 and interior articulamentum 3 are all made of TPU material injection moldings.
In this way, the utility model forms epidermis in such a way that TPU materials (thermoplastic polyurethane elastomer) are by injection molding
Layer 1 and interior articulamentum 3 belong to identical since both thermoplastic polyurethane elastomer and ETPU particles belong to polyurethane material
Material classification, there is preferable blending, can to can be connected between epidermis 1 and interior articulamentum 3 and buffer layer 2 for
One entirety, improves the quality of entire solid tyre.The solid tyre that the utility model is formed simultaneously, epidermis 1 are compared
It is hard in buffer layer 2, the buffer layer 2 is soft compared to epidermis 1, and the prior art is essentially all that epidermis 1 is soft
, the inside is hard, and practical damping effect is poor；In addition, the utility model is stayed by allowing between epidermis 1 and interior articulamentum 3
There is annular gap 4 so that the active force that 1 inside articulamentum 3 of epidermis transmits will all pass through buffer layer 2, it is ensured that Suo Youzuo
It firmly can all obtain the cushioning effect of buffer layer 2.
As depicted in figs. 1 and 2, the interior articulamentum 3 has the covering portion 31 and and clad being coated on outside buffer layer 2
The interconnecting piece 32 being integrally connected is also formed with several screw connecting holes 33, each screw connecting hole 33 on the interconnecting piece 32
Penetrate through two sides of interconnecting piece 32.So by the molding of covering portion 31, can improve interior articulamentum 3 and buffer layer 2 it
The transmission of intermolecular forces, and both allow the contact area that can have bigger, to greatly improve interior articulamentum 3 and buffer layer
The tight ness rating connected between 2.
As shown in Figure 1, in order to further increase the non-skid property of epidermis 1, it is also formed in a ring on the epidermis 1
Several groups groove made of array, every group of groove all have first groove 11 and second groove 12, the first groove 11 along
The circumferential direction of epidermis 1 extends, and angle of the second groove 12 then between first groove 11 is acute angle.Utilize the first ditch
Slot 11 and second groove 12 are formed by three-dimensional Skidproof structure, so as to greatly improve the anti-of entire ETPU solid tyre
Slip energy.
