Description

A kind of elasticity non-inflatable tyre

Technical field

The utility model is related to tire art, especially a kind of non-inflatable tyre.

Background technology

Automobile non-inflatable tyre is also referred to as automobile non-inflatable tyre, refers to and realizing damping, buffering not by air pressure The tire of performance.The material selection of non-inflatable tyre is compared conventional tire with structure design and is very different, and non-inflatable tyre is general Using structures such as high molecular material disc or wire sides tradition is played on the basis of ensureing the performances such as reliable and energy-saving The unexistent advantage of tire.Since 21 century, each tyre company and research department obtain in terms of non-inflatable tyre research and development in succession Some achievements.

French Michelin proposes earliest and production non-inflatable tyre, releases Tweel non-inflatable tyres for the first time in 2005, it Including wheel hub, polyurethane spoke, the shear band and tread rubber being directly wound on outside spoke, the not no inflatable inner tube of middle transition, This non-inflatable tyre do not have to consider puncture explosion proof conditions, it is simple in structure, be easy to renovation, gripping power is strong, rolling resistance is small, noise It is low, more resistant.Polyurethane spoke, more resistant to impact, can play the role of the springs such as buffering than alloy rim.The U.S. in 2008 The research staff at Resilient technology companies and state of Wisconsin university Madison branch school condensate engineering science center utilizes bionical Learn principle and develop a kind of novel non-inflatable tyre --- honeycomb tyre.It applies to honeycomb hexagonal structure on tire, makes Tire operation when generate heat low, rapid heat dissipation, and can road pavement impacted certain cushioning effect, now made by US military With.Japanese bridgestone company in 2014 releases 2nd generation new A irFree Concept and exempts from air inflation conception tire.It was using both Can keep high intensity again can keep the resin material of flexibility, and grid extending direction is inside and outside on the contrary, the mould for passing through deviation angle It is quasi- to calculate, the intensity and cushion performance of tire can be optimized.

Now automobile non-inflatable tyre spoke disc design mostly uses straight panel or helical arc design, straight-plate-type disc by There is non-directiveness when compressive strain, have the shortcomings that unstable point, it cannot be guaranteed that good ride performance, especially runs at high speed When, due to the unstable point property of supporting deformation, automobile vibration can be made violent, and the non-inflatable tyre web of helical arc design is difficult to hold By larger load.In recent years, many businessmans are also continuously improving design, propose a variety of innovation structures to meet the market requirement.

Utility model content

The utility model aim is to provide a kind of can exempt to inflate radial with the elasticity of certain elastic damping effect Tire.

To achieve the above object, following technical scheme is used：The utility model includes mainly wheel hub, elastic spoke and outer Tire, elastic spoke are cyclic annular and are socketed between wheel hub and cover tire that elastic spoke is formed by spoke disc circumference array, the wheel The shape of spoke disc is formed by one section of arch camber line, two sections of broken lines and two rounded corners, and two sections of arch camber line are broken line, every section Broken line connects rounded corner, and the side of two rounded corners is connected in angle formula；Spoke disc is formed along wheel rim rotation center array distribution Spoke.

Further, the spoke is molded by rubber integration system.

Further, the variable thickness of the spoke disc, and the disc shape of every group of spoke is consistent.

Compared with prior art, the utility model has the following advantages that：

1, spoke when landing load by, with stable elastic deformability, capable of playing cushioning buffer effect.

2, the broken line of spoke disc can reinforce the bending strength of arch camber line disc and have directional deformation effect.

Fig. 3 is another structure chart after the spoke disc refinement of the utility model.

Fig. 4 is another structure chart after the spoke disc of the utility model thickeies.

Fig. 5 is the spoke disc thickening of the utility model and another structure chart after chamfering increase.

Drawing reference numeral：1- wheel hubs, 2- elasticity spoke, 3- cover tires.

Specific implementation mode

The utility model is described further below in conjunction with the accompanying drawings：

As shown in Figure 1, 2, the utility model includes mainly wheel hub 1, elastic spoke 2 and cover tire 3, and elastic spoke 2 is ring-type And be socketed between wheel hub 1 and cover tire 2, the elasticity spoke is formed by spoke disc circumference array, the shape of spoke disc by One section of arch camber line, two sections of broken lines and two rounded corners are formed, and two sections of arch camber line are broken line, and every section of broken line connection circle falls The side at angle, two rounded corners is connected in angle formula；Spoke disc forms spoke along wheel rim rotation center array distribution.Broken line thickeies The thickness of arch circular arc both sides, and direction is guided for circular arc deformation, the bending strength of arch camber line disc can be reinforced simultaneously With directional deformation effect, the shortcomings that overcoming vertical bar disc, and the spoke is made of rubber integrated molding, spoke by With stable flexible deformation when landing load.

The variable thickness of the spoke disc, and the disc shape of every group of spoke is consistent.

Fig. 3 is another structure of elastic non-inflatable tyre, and spoke disc is thinner in the structure, and thickness is smaller, and along rotation Turn the distribution of center comparatively dense, when the structure is by landing load, with ground contact bending part spoke disc be not subject to support force and Only directional deformation transmits load by other spoke disc by stretching.

Fig. 4 is another structure of elastic non-inflatable tyre, and spoke disc is thicker in the structure, and spoke disc uniformly divides Cloth, spoke disc, which can be bent and deformed, to be born larger landing load and has certain elasticity.

Fig. 5 is another structure of elastic inflated tire, and spoke disc is thicker in the structure, and broken line both sides fillet is larger, Web is uniformly distributed, and spoke disc, which can be bent and deformed, to be born larger landing load and have certain elasticity.

Landing load is transferred to spoke disc by cover tire, and the disc in spoke is by bending, stretching or compression, over the ground Face is played a supporting role, and can generate certain elasticity so that tire has certain vibration reduction and cushioning effect.

Embodiment described above is only that preferred embodiments of the present invention are described, not to this practicality Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this The various modifications and improvement that the technical solution of utility model is made should all fall into the protection of the utility model claims book determination In range.
