Abstract
The utility model provides a wheel capable of normally running when a tire is flat. The wheel comprises a hub, a spoke, a tire and a tire supporting piece. The spoke is arranged between the hub and the tire supporting piece. The tire supporting piece comprises three rims which are arranged in parallel and are relatively fixed. Each rim comprises a rim seat and flanges which are distributed on the two sides of the rim seat. A middle rim is used for installing and supporting an inflatable tire. Two side rims are used for installing and supporting solid tires. The outer diameter of the solid tires is larger than the minimum outer diameter of the inflatable tire when the inflatable tire is flat and is smaller than the outer diameter of the inflatable tire when the inflatable tire is fully inflated. During normal running, the inflatable tire in the middle touches the ground and the solid tires on the two sides are suspended in the air, so that the wheel has the advantages that the shock absorbing performance of the inflatable tire is good and the running speed is fast. When the inflatable is punctured or the tire is flat because the pressure is insufficient, the solid tires on the two sides touch the ground, a vehicle can continuously run and the situation that the vehicle cannot normally run due to a lack of field repair conditions is avoided.
Description
Technical field
The utility model relates to vehicle, more specifically, relates to the wheel of vehicle.
Background technology
The wheel of the wheel of vehicle (especially non-power-driven vehicle) mainly is the rotary components that bears load that is made of wheel hub, spoke, wheel rim and tire.Tire is the annular arrangement elastic rubber product that rolls the ground connection of various vehicles or mechanically assembling, is divided into band tyre and air-inflation tyre, and air-inflation tyre mainly is made of cover tire and the inner tube of a tyre.Wheel rim is that spoke is at the support unit between wheel hub and wheel rim on the wheel at the parts of wheel installation and supporting tire, and wheel hub is installed on the axletree and and axletree formation revolute pair.
In the prior art, a wheel only has a tires, band tyre or air-inflation tyre.Air-inflation tyre is applied on the most vehicle, has the advantage that quality is light, damping performance good and moving velocity is fast, but pierced through by pricking object easily or other reason causes gas leakage, and chaufeur often lacks the spot repair condition, causes normally to travel.Band tyre is not afraid of and is stabbed, but in the quality, damping performance is poor, moving velocity is slow, be difficult to be widely adopted as major part.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of wheel that still can normally travel behind tire flat.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of wheel, comprise wheel hub, spoke, tire and tire strut member, spoke is between wheel hub and tire strut member, the tire strut member comprises and being set up in parallel and relatively-stationary three road wheel rims, the per pass wheel rim comprises the wheel ring support and is distributed in the wheel rim of wheel ring support both sides, middle wheel rim is installed and the support and inflation tire, the both sides wheel rim is installed and supported band tyre, and the external diameter of band tyre should satisfy: air-inflation tyre is revealed the external diameter of external diameter ﹤ air-inflation tyre under inflation pressure of minimum outer diameter ﹤ band tyre when becoming flat.
Above-mentioned wheel, the external diameter of the external diameter ﹤ band tyre of wheel rim in the middle of the external diameter ﹤ of both sides wheel rim.
Above-mentioned wheel, the band tyre of air-inflation tyre and both sides has the circular clearance.
Above-mentioned wheel, tire strut member are mono-block cast.
Above-mentioned wheel, tire strut member are mono-block cast.
In normal driving process, middle air-inflation tyre lands, and the band tyre of both sides is unsettled, has guaranteed the advantage that the air-inflation tyre damping performance is good, moving velocity is fast.When air-inflation tyre punctures or the not enough tire of air pressure when becoming flat, the band tyre of both sides lands, and vehicle can continue to travel, and has exempted owing to lack the spot repair condition, causes the predicament that can not normally travel.
Description of drawings
Below in conjunction with accompanying drawing to further detailed explanation of the utility model:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of tire strut member among Fig. 1.
Among the figure: 1 tire strut member, 2 air-inflation tyres, 3 band tyres, 4 middle wheel rims, 5 both sides wheel rims.
The specific embodiment
Because inventive point of the present utility model is tire strut member and tire, so only show these two parts among Fig. 1 and Fig. 2.As illustrated in fig. 1 and 2, a kind of wheel comprises wheel hub, spoke, tire and tire strut member 1, and spoke is between wheel hub and tire strut member.The tire strut member comprises and being set up in parallel and relatively-stationary three road wheel rims that the per pass wheel rim comprises the wheel ring support and is distributed in the wheel rim of wheel ring support both sides.Middle wheel rim 4 is installed and support and inflation tire 2, and band tyre 3 is installed and supported to both sides wheel rim 5.The external diameter of band tyre should satisfy: air-inflation tyre is revealed the external diameter of external diameter ﹤ air-inflation tyre under inflation pressure of minimum outer diameter ﹤ band tyre when becoming flat.
Specific to the tire strut member, the external diameter of middle wheel rim should satisfy: the external diameter of the external diameter ﹤ band tyre of wheel rim in the middle of the external diameter ﹤ of both sides wheel rim.
The band tyre of air-inflation tyre and both sides has the circular clearance, the one, for puncture when air-inflation tyre or the not enough tire of air pressure when becoming flat as spatial accommodation, the 2nd, the friction for fear of between the adjacent tires prevents damaged tyres.
Particularly, the tire strut member is mono-block cast, and namely inblock cast forms.
Claims (5)
1. wheel, comprise wheel hub, spoke, tire and tire strut member, spoke is between wheel hub and tire strut member, it is characterized in that: the tire strut member comprises and being set up in parallel and relatively-stationary three road wheel rims, the per pass wheel rim comprises the wheel ring support and is distributed in the wheel rim of wheel ring support both sides, middle wheel rim is installed and the support and inflation tire, the both sides wheel rim is installed and supported band tyre, and the external diameter of band tyre should satisfy: air-inflation tyre is revealed the external diameter of external diameter ﹤ air-inflation tyre under inflation pressure of minimum outer diameter ﹤ band tyre when becoming flat.
