Abstract
The utility model provides a bicycle inner tyre needing no inflation, the shock absorption effect which is equal to an inflation tyre is played by making use of a spring, the elasticity of synthetic rubber and an internal hollow structure. The utility model omits unexpected trouble and economic loss brought by tyre piercing, tyre exploding and gas leakage to people, an inner bicycle tyre and an outer bicycle tyre are integrated into one body, the manufacturing cost does not fundamentally increased, the long lifetime is improved, and the tyre can be used till the bicycle being discarded.
Description
The utility model relates to a kind of cycle tyre that need not inflate.
Existing cycle tyre is an inflatable, divides inside and outside two tires, uses to take place often to prick accidents such as tire, blast, gas leakage, brings beyond thought trouble to people.According to investigation, this type of accident accounts for more than 60% of bicycle repairing.
The purpose of this utility model provides a kind of cycle tyre that need not inflate, in use, never inflates, and saves the bundle tire, tire blast, trouble and economic loss that gas leakage brings to people.
The utility model is achieved in that a spring along wheel external diameter layout, becomes circular, and axle of spring is to be the circle in the center of circle with the axis wheel, and the spring transversal surface is similar in appearance to the tire transversal surface, and each little coil spring becomes an inclination angle [theta] with this radius of wheel.Spring is cast in the neoprene with the bead coil and the fiber of two wheel external diameter sizes, forms a boring, outside sealing, and the centre accompanies the cycle tyre of spring and bead coil.Because spring and elastomeric elasticity and in-to-in hollow structure, can reach the damping effect identical with inflation tyre, all become an angle of inclination owing to play each little coil spring of cushioning effect again, can exempt because of strenuous vibration causes spring generation deformation and can not reply with this radius of wheel.Bead coil is fastened on the rim tire.
The utility model is compared with the filling gas bicycle tire, and is non-inflatable, saved troubles such as bundle tire, blast, gas leakage.Inside and outside two tires combine together, and cost does not have to improve substantially, and make simply, and the tire life-span is improved, can use to bicycle discarded till.
Be described further below in conjunction with accompanying drawing.
Fig. 1 is that vertical rubber of the present utility model partly cuts open from figure.
Fig. 2 is the A-A section-drawing of Fig. 1.
With reference to Fig. 1, spring (1) becomes the great circle ring-type, is cast in the neoprene (3) with bead coil (2).Form a boring (4), outside sealing, the centre accompanies the cycle tyre of spring (1) and bead coil (2).Each ringlet of spring (1) all becomes a tiltangle with this radius of wheel, 5 °≤θ≤30 °.When tire with when contacting, spring (1) compresses with being tilted, contiguous several coil springs are also worked.Select suitable spring (1) and inclination angle [theta], even stressed very big, cavity (4) is pressed not have, spring (1) still can be returned to original state, and under the general stressing conditions, tire can play the damping effect the same with inflation tyre only by a bit of distance of vertical compression.Bead coil (2) is fastened on the rim tire.
The utility model is when implementing, and spring (1) should twine close more well more under the prerequisite of the damping effect of obtaining.
Spring (1) can be wound in earlier and axis normal, flattens with external force again, is cast in after the answer in the neoprene (3) again.
The neoprene of landing part (3) is preferably thickeied.
The utility model even can make long material, the section of being cut into is fixed on the rim again.
Claims (3)
1, one by spring (1), bead coil (2), and the cycle tyre that need not inflate that neoprene (3) constitutes is characterized in that the outside sealing of neoprene (3), boring (4), the centre accompanies spring (1) and bead coil (2).
2, the cycle tyre that need not inflate according to claim 1 is characterized in that spring (1) axis is to be the circle in the center of circle with the axis wheel.
3, the cycle tyre that need not inflate according to claim 1 and 2 is characterized in that each ringlet of spring (1) becomes a tiltangle with this radius of wheel, 5 °≤θ≤30 °.
