Abstract
The utility model provides a subtract heavy tire. Polyurethane foam tire among the prior art, through polyurethane foam moulding by casting, it is solid construction. But this kind of solid tire has following shortcoming: tire itself is heavier, and the resistance is great, and material cost is higher. The utility model provides a subtract heavy tire, including core wheel and cover tire, core wheel and cover tire set up its characterized in that along same rotation axis is rotatory: the cross -section of core wheel is the hollow annular structure, and the cross -section of core wheel is wound the rotation axis gyration and is formed the annular structure, the cover tire cladding is on the core wheel. The utility model discloses simple structure, reasonable in design, the bearing capacity is good, and save material reduces whole weight.
Description
Technical field
The utility model relates to a kind of loss of weight tire, belongs to vehicle body fittings.
Background technology
Loss of weight tire of the prior art usually have inflatable with solid two kinds.The wherein tire of inflatable, just can not continue to use after scuffing.And this tire is when mounted, easily there is the situation of fracture, and when using easily and wheel rim depart from.And solid tire, scratch although be not afraid of sharp thing, himself is too heavy, and resistance is comparatively large, and material cost is higher.Tire solid in addition, its damping performance is general.
Polyurethane foam tire of the prior art, by polyurethane foam moulding by casting, it is solid construction.But this solid tire, has following shortcoming: tire itself is heavier, resistance is comparatively large, and material cost is higher.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and provides a kind of reasonable in design, and bearing capacity is good, saves material, reduces the loss of weight tire of overall weight.
The technical scheme in the invention for solving the above technical problem is: this loss of weight tire, comprise core wheel and cover tire, core wheel and the same S. A. rotary setting of outer tyre bead, it is characterized in that: the cross section of described core wheel is hollow cyclic structure, the cross section of core wheel forms cyclic structure around S. A. revolution, and described cover tire is coated on core wheel.Due to the setting of core wheel, overall weight can be reduced, thus cost-saving, reduce resistance.
Described in the utility model wheel on core outer surface is evenly placed with some reinforced ribs along the hoop of S. A..The setting of reinforced rib, can increase on the one hand the bearing capacity of core wheel, make the bearing capacity of tire entirety unaffected, on the other hand, can increase core wheel and cover tire in conjunction with time intensity, raising structural strength.
Core wheel described in the utility model comprises supporting walls, lower support wall and symmetrically arranged two groups of sidewalls, and two groups of above-mentioned supporting walls and two groups of sidewalls are linked to be enclosed construction.
Sidewall described in the utility model is in arch on the axial direction of S. A., and described upper supporting walls be arch in the radial direction of core wheel toward lateral direction, and described lower support wall direction inside the footpath of core wheel is yearned for is arch.Arch configuration, can promote pressure resistance further, thus improves the bearing capacity of core wheel.
The utility model compared with prior art, has the following advantages and effect: structure is simple, reasonable in design, due to the setting of core wheel, can reduce overall weight, thus cost-saving, reduces resistance.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the fragmentary, perspective view of the loss of weight tire in the utility model embodiment.
Fig. 2 is the structural representation of core wheel.
Fig. 3 is the perspective view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
Embodiment 1.
See Fig. 1 to Fig. 3, the loss of weight tire of the present embodiment comprises core wheel 1 and cover tire 2, and core wheel 1 and cover tire 2 are along same S. A. L rotary setting, and the cross section of core wheel 1 is hollow cyclic structure, the cross section of core wheel 1 is turned round around S. A. L and forms cyclic structure, and cover tire 2 is coated on core wheel 1.Due to the setting of core wheel 1, overall weight can be reduced, thus cost-saving, reduce resistance.
Core wheel 1 in the present embodiment is made for blow molding process, during making, first core wheel 1 is put into mould, then carries out polyurethane foam cast, thus forms cover tire 2.
Hoop along S. A. L on core wheel 1 outside face in the present embodiment is evenly placed with some reinforced ribs 11.The setting of reinforced rib 11, can increase on the one hand the bearing capacity of core wheel 1, make the bearing capacity of tire entirety unaffected, on the other hand, can increase core wheel 1 and cover tire 2 in conjunction with time intensity, raising structural strength.
Core wheel 1 in the present embodiment comprises supporting walls 12, lower support wall 13 and symmetrically arranged two groups of sidewalls 14, and two groups of above-mentioned supporting walls and two groups of sidewalls 14 are linked to be enclosed construction.
Sidewall 14 in the present embodiment is in arch on the axial direction of S. A. L, and upper supporting walls 12 be arch in the radial direction of core wheel 1 toward lateral direction, and lower support wall 13 direction inside the footpath of core wheel 1 is yearned for is arch.Arch configuration, can promote pressure resistance further, thus improves the bearing capacity of core wheel 1.
Above content described in this specification sheets is only to the explanation of the utility model example.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment; only otherwise depart from the content of the utility model specification sheets or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
