Abstract
The present invention relates to the profile design without interior wheel rim, more particularly to a kind of resistance to knocking over without interior wheel rim.A kind of resistance to knocking over without interior wheel rim, this includes wheel rim without interior wheel rim, wheel rim upper end position is provided with boss, make wheel rim into S-shaped, the scope for the difference in height B for and putting with wheel rim on the inside of boss is 1~5mm, it is 3mm ~ 12mm that wheel rim, which and puts radian fillet Ra scopes of design, and radian fillet Rb scopes of design are 6mm ~ 15mm.The present invention designs a boss in wheel rim upper end position, makes wheel rim into S-shaped, when tyre inflating is run, wheel rim boss is inlayed after compression into the sizing material of tyre bead, allow tire to be preferably fixed on wheel rim, reduce the activity of tyre bead, effectively constrain movement of the tyre bead radially with transverse direction.
Description
Technical field
The present invention relates to the profile design without interior wheel rim, more particularly to a kind of resistance to knocking over without interior wheel rim.
Background technology
Wheel rim is the important component for connecting tire and automobile chassis, and automobile transmits control of the torque completion to tire by wheel rim
System, once wheel rim, which breaks down, will cause automobile initiation security incident out of control.Just quickly being substituted without interior radial at present has
Interior tire, becomes the main product in market, and during being replaced, particularly short-distance heavy duty is without interior tire, in high pressure, big
The problem of tire knocking over easily occurs under load operation, is a great security risk for road user.Cause no lubrication groove
The reason for tire easy knocking over is mainly that the wheel rim without interior wheel rim lacks the structure for suppressing tyre bead movement, it is impossible to constraint tyre bead well
Laterally and radially move, when tyre bead produces moderate finite deformation, easily skidded off along wheel rim camber line.
Traditional approach solves the problems, such as knocking over, main using increase bead bundle root number of twisting, improves tyre bead integral rigidity
And intensity, tyre bead deformation is reduced, so as to reduce the incidence of knocking over.But there are doubling, increase between traditional wire loop steel wire
After winding the number of turns, flexural rigidity will be increased, it is difficult to cause to fill tire, tyre bead difficulty increase in place, reduces matching somebody with somebody for tyre bead and wheel rim
Conjunction property, adds the vibration of tyre bead.It is thickening that another aspect reinforced bead structure will make tyre bead integrally become larger, and weight rises, and both can
Rolling resistance is caused to rise, oil consumption increase, can also increase tyre bead heat, trigger tyre bead heat damage.
Fig. 1 is normally without interior wheel rim, wheel rim portion design radian is larger, and transition is rounder and more smooth, with contacting with each other for tyre bead
Area is smaller, poor to the encapsulation of tyre bead, and the round and smooth design of transition is unable to laterally and radially moving for operative constraint tire, single
The pure deformation that tyre bead is constrained by the circumferential tightening force of bead bundle.
The content of the invention
In order to solve above-mentioned technical problem, the object of the present invention is to provide a kind of resistance to knocking over without interior wheel rim, in the nothing
Wheel rim makes wheel rim profile tire bead base is stuck in wheel rim into S types by designing a boss in wheel rim upper end position, from
And the movement of tyre bead is constrained, solve the problems, such as the easy knocking in the case of high-pressure heavy-load without interior tire.
In order to realize above-mentioned purpose, present invention employs following technical solution：
A kind of resistance to knocking over without interior wheel rim, this includes wheel rim without interior wheel rim, and wheel rim upper end position is provided with boss, makes wheel rim into S
Shape, the scope for the difference in height B that boss inner side and puts with wheel rim is 1~5mm, and wheel rim, which and puts radian fillet Ra scopes of design, is
3mm ~ 12mm, radian fillet Rb scope of design are 6mm ~ 15mm.
Preferably, the scope for the difference in height B for and putting with wheel rim on the inside of the boss is 2 ~ 3mm, wheel rim and point
Radian fillet Ra scopes of design are 5mm ~ 7mm, and radian fillet Rb scopes of design are 7mm to 10mm.
Preferably, it is 10 ~ 15mm that the wheel rim, which and put with the difference in height at the top of boss,.
As further preferably, it is 12 ~ 13mm that the wheel rim, which and put with the difference in height at the top of boss,.
As most preferably, the scope for the difference in height B for and putting with wheel rim on the inside of the boss is 2.5mm, wheel rim with
Point radian fillet Ra scopes of design are 6mm, and radian fillet Rb scope of design 8mm, H1 are highly 12.7mm.
The present invention be it is a kind of be used for 15 ° of TBR truck tires without interior wheel rim, inflation pressure of tire is in more than 700Kpa, this hair
Bright to design a boss in wheel rim upper end position, making wheel rim, when tyre inflating is run, wheel rim boss is inlayed after compression into S-shaped
Into in the sizing material of tyre bead, allow tire to be preferably fixed on wheel rim, reduce the activity of tyre bead, effectively constrain tyre bead radially
With horizontal movement.When boss height is less than 1mm, the not anti-knocking over effect of wheel rim, when boss height is more than 5mm, will cause
Tyre bead difficulty in place increases, and when boss height is in 1~5mm, tire can make tyre bead in place by larger internal pressure, play anticreep
Enclose effect.
Brief description of the drawings
Fig. 1 is the topology view normally without interior wheel rim.
Fig. 2 is structure diagram of the invention without interior wheel rim.
Fig. 3 is wheel rim partial enlarged view.
Fig. 4 is structure diagram when tire is run.
Embodiment
The embodiment of the present invention is made a detailed explanation below in conjunction with the accompanying drawings.
A kind of resistance to knocking over as shown in Figure 2 and Figure 3 without interior wheel rim, this includes wheel rim without interior wheel rim, and wheel rim upper end position is set
Boss 1 is equipped with, making wheel rim, the inner side of boss 1 with wheel rim and the scope of the difference in height B of point is 2.5mm, wheel rim into S-shaped
It is 6mm and put radian fillet Ra scopes of design, and radian fillet Rb scopes of design 8mm, H1 are highly 12.7mm.
When Fig. 4 runs for tire, tyre bead with the mated condition of wheel rim, inlay into tyre bead sizing material, plays solid by wheel rim boss
Conclude a contract or treaty the effect of beam tyre bead activity, lift anti-knocking over performance.
By the way that 12R24.5 tires are separately mounted to carry out hydraulic pressure demolition contrast in fact on normal wheel rim and the wheel rim of the present invention
Test, the wire loop all enclosed using 1.8 steel wire windings 72 of Ф, is shown through indoor hydraulic pressure blasting result, on wheel rim of the present invention
Data more normal wheel rim lifting 24%, illustrate that the present invention has the ability for lifting the anti-knocking over of tire.
Specific data such as following table：
| Project | Normal wheel rim | Invention wheel rim |
| Hydraulic pressure demolition | 2540kPa | 3150kPa |
