Specific implementation mode
With reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu is fully described by, it is clear that and described embodiment is only a part of the embodiment of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Many details are elaborated in the following description in order to fully understand the utility model, but this practicality is new
Type can also be implemented using other different from other manner described here, and those skilled in the art can be without prejudice to this reality
With doing similar popularization in the case of novel intension, therefore the utility model is not limited by following public specific embodiment.
As depicted in figs. 1 and 2, the utility model discloses a kind of coiled spring tyre, including wheel rim 10 and it is fixed on wheel
The carcass 20 in 10 outside of rim, the carcass includes principal screw spring 21 and auxiliary helical spring wire side 22.As shown in figure 4, the master
Helical spring 21 forms ring-type by single piece of metal cylindroid helical-coil compression spring is end to end, and the auxiliary helical spring wire side 22 includes
Several auxiliary screw springs 221 made of the compression of same metal cylindrical screw, and adjacent auxiliary screw spring 22 is mutual
It nests together, the both ends of the auxiliary screw spring 221 form free end, as shown in Figure 3, Figure 5 and Figure 6.The principal screw
The equally spaced auxiliary screw spring 221 in the auxiliary helical spring wire side 22 of spring 21, and the principal screw spring 21
Fixed with the wheel rim 10, in the auxiliary helical spring wire side 22 two free ends of auxiliary screw spring 221 respectively with it is described
Wheel rim 10 is fixedly connected.
Carcass 20 is formed by principal screw spring 21 is nested with auxiliary helical spring wire side 22 in the spring tyre, is being moved through
Cheng Zhong, auxiliary helical spring wire side 22 are first contacted with ground, are transferred force to again on principal screw spring 21 after compressive deformation, principal screw
Spring 21 bears Main Load, and auxiliary helical spring wire side 22 bears minor loading, principal screw spring 21 and auxiliary helical spring wire side
22 can generate larger deformation, it is thus possible to generate buffering effect identical with rubber tyre.Since the material of carcass is gold
Belong to, thus carcass 20 can effectively resist ground sharp object puncture or small arms attack, and not will produce the case where blowing out,
Also there is the characteristic for resisting high/low temperature, it is thus possible to effectively improve the tolerance in face of complex environment.Meanwhile auxiliary helical spring
By more same metal cylindroid helical-coil compression springs, parallel nested constitutes ring network to wire side 22 two-by-two, and closeness is higher, Neng Gouyou
Effect foreign matter is avoided to enter in carcass, and when the auxiliary screw spring 221 for constituting auxiliary helical spring wire side 22 occurs one or several
When root is broken, whole use is not interfered with, the major-minor structure variable stiffness coil spring tire to improve the utility model makes
Use the service life.
As shown in Figure 1 to Figure 3, the steel wire diameter that the principal screw spring 21 uses is more than the auxiliary screw spring 221
The steel wire diameter used.Thus the structural strength of principal screw spring 21 is greater than auxiliary screw spring 221 so that principal screw spring
21 non-deformabilities are strong, can resist larger impact, and principal screw spring 21 and auxiliary screw spring 221 form variation rigidity
Structure, auxiliary screw spring 221 are first contacted with ground, are transferred force to again on principal screw spring 21 after compressive deformation, twice into
Row buffering increases the comfort level of seating to reduce the seismaesthesia of occupant to the maximum extent.
As shown in Fig. 2, Fig. 3 and Fig. 7, the tire further includes fixed band 30, and the fixed band 30 is fixed on the wheel rim
On 10 periphery.The inboard portion of the principal screw spring 21 is located between the wheel rim 10 and fixed band 30, and the main spiral shell
The part that rotation spring 21 is located between the wheel rim 10 and fixed band 30 does not have auxiliary screw spring 221.Due to principal screw bullet
The steel wire in the annular inboard face of spring 21 passes through fixed band 30, thus when principal screw spring 21 is broken, fixed band 30 can
Ensure that principal screw spring 21 maintains overall structure not deform, bearing capacity will not vary widely, and can continue to move
It is relatively remote, to increase reply extreme case adaptibility to response.
Further, as shown in Figure 2 and Figure 7, the fixed band 30 is equally spaced on the anchor ring of the wheel rim 10 sets
Several arc grooves 31 are equipped with, the part that the principal screw spring 21 is located between the wheel rim 10 and fixed band 30 is arranged in institute
It states in arc groove 31, and the width of the arc groove 31 is adapted with the steel wire diameter of the principal screw spring 21, so that
The connection that principal screw spring 21 can be stablized with fixed band 30 avoids the coupling part of the two from forming shear surface and causes stress concentration
And be broken, and then increase the service life of principal screw spring 21, reduce use cost.
Further, as shown in Figure 2 and Figure 7, equally spaced on the circumferential surface of the fixed band 30 to be provided with several radial directions
Hole 32, the fixed band 30 are fixedly connected across the radial hole 32 with the wheel rim 10 by bolt, ensure fixed band 30 with
Wheel rim 10 is reliably connected.
Further, as depicted in figs. 1 and 2, the spring tyre further includes two fixed rings 40, the auxiliary helical spring
The both ends of auxiliary screw spring 221 are fixedly connected with the fixed ring 40 respectively in wire side 22, and the fixed ring 40 is fixed to institute
In the groove for stating 10 both sides of wheel rim.For auxiliary screw spring 221 when deforming, a part of load can be along auxiliary screw spring
221 axial direction transmits, since the both ends of auxiliary screw spring 221 are connect with fixed ring 40 respectively, thus this fractional load
It can be transmitted in fixed ring 40, the load that principal screw spring 21 undertakes be reduced, to extend its service life.
Further, as depicted in figs. 1 and 2, multiple axial holes are arranged at intervals in the peripheral side of the fixed ring 40
41, the fixed ring 40 passes through the axial hole 41 to be fixed with the wheel rim 10 by bolt, ensures fixed ring 40 and wheel rim 10
Be reliably connected.
