The tyre cavity is divided into an inner cavity 11 and an outer cavity 12 which are mutually independent through the elastic separating piece 2, when the tyre 1 is burst or deflated, the outer cavity 12 is deflated, the air pressure is reduced due to deflation, and the inner cavity 11 is expanded due to pressure difference, so that the elastic separating piece 2 is forced to elastically deform from the inner cavity 11 to the outer cavity 12 until the inner cavity 11 fills the whole tyre cavity. After the tire casing 1 is deflated or the tire is burst, the air pressure in the inner cavity 11 can be controlled to be 50-80%, the weight of the whole vehicle can be supported, the radius of the wheels is almost unchanged, the running performance of the vehicle including steering performance, braking performance, steering performance and the like is almost unchanged, normal running can be continued, and traffic accidents caused by the tire casing 1 is burst or deflated can be effectively reduced.
According to some preferred embodiments of the utility model, as shown in fig. 3, the elastic separator 2 comprises two first portions 21 for respectively sealing connection with the carcass portion of the carcass 1 and a second portion 22 connecting the two first portions 21, at least one of the first portions 21 and the second portions 22 being elastically deformable. The elastic separating piece 2 is in sealing connection with the tyre foot position of the tyre casing 1 through the two first parts 21, so that the tyre cavity is separated into at least two mutually isolated cavities, and the structure is simple. Preferably, the entire area of the second portion 22 is capable of elastic deformation. Therefore, when the outer tire 1 is burst or deflated, the elastic partition piece 2 has enough elastic deformation to enable the inner cavity 11 to fill the whole tire cavity, so that the weight of the vehicle is supported, and the vehicle is ensured to continue to run normally. It is further preferred that both the second portion 22 and the first portion 21 are capable of elastic deformation. The first portion 21 may be attached to the foot portion of the casing 1 by bonding, fastening, heat staking, or the like, as will be appreciated by those skilled in the art.
According to some preferred embodiments of the present utility model, as shown in fig. 3, both the first portion 21 and the second portion 22 are curved and the second portion 22 is opposite to the curved direction of the first portion 21. That is, the elastomeric partition 2 divides the tire cavity into two cavities, each generally annular, matching the contour of the casing 1. More specifically, the section of the elastic partition 2 is of an Ω -shape opening toward the inner side surface of the rim 3.
According to some preferred embodiments of the utility model, the elastic separator 2 is a diaphragm made of an elastic material. The specific materials of the elastic material are not described and limited, and are conventional elastic materials such as rubber and polyurethane elastomer with high strength, high elasticity or high elongation, high temperature resistance and moderate hardness, which are known to those skilled in the art. For some physical performance parameters of the elastic separator 2, such as, but not limited to, tensile strength: 12-15 Mpa; surface hardness: SHA 40-45; material elongation: 200-300%; thickness: 1.5-2.5 mm. The specific ones are not limited.
According to some preferred embodiments of the present utility model, the number of the elastic spacers 2 is plural, and the plural elastic spacers 2 are stacked in the direction from the inner chamber 11 to the outer chamber 12 or from the outer chamber 12 to the inner chamber 11. When the outer layer of the elastic separation piece 2 is in hard contact with the inner wall of the outer tire 1 after the outer tire 1 is inflated, the inner layer can still play a role in isolation, and normal running of the wheel is guaranteed. As an alternative embodiment, a plurality of elastic partitions 2 are provided separately to partition the inner chamber 11 into a plurality of separate chambers independent of each other. Similarly, the inner cavity 11 is formed into a plurality of independent isolation cavities through the plurality of elastic separation pieces 2, when the elastic separation piece 2 in one isolation cavity is damaged due to hard contact between the outer layer of the elastic separation piece 2 and the inner wall of the outer tire 1 after the outer tire 1 is burst or deflated, the other isolation cavities can still play an isolation role, and normal running of the wheels is ensured. As a modified example, the number of the elastic spacers 2 is one, a plurality of isolation chambers (not shown) which are isolated from each other and open to the inner side of the rim 3 are formed on one surface of the elastic spacers 2 facing the inner side of the rim 3, and wall surfaces at the openings of the plurality of isolation chambers are hermetically connected to the inner side of the rim 3. For example, the elastic separator 2 is in a honeycomb structure, so that the structural strength is higher than that of a single-layer or multi-layer elastic diaphragm, and the continuous running of the flat tire can be better ensured.
According to some preferred embodiments of the present utility model, the inner cavity 11 and the outer cavity 12 share an air inlet and two air outlets, wherein one air outlet is communicated with the inner cavity 11, the other air outlet is communicated with the outer cavity 12 through an air inflation tube 7 arranged in the inner cavity 11 and connected to the elastic partition 2, a one-way valve (not shown) is arranged at the joint of the air inflation tube 7 and the elastic partition 2, the air inflation tube 7 is a flexible air inflation tube, namely the air inflation tube 7 can be bent and stretched, the air inflation tube 7 is a conventional plastic air tube in the prior art, the maximum length of the air inflation tube 7 can be adapted to the expansion of the inner cavity 11 until the elastic partition 2 is attached to the inner wall surface of the outer tire 1, that is, when the inner cavity 11 is expanded to fill the whole tire cavity, a pulling force in the direction of the rim 3 is not exerted on the elastic partition, and when the air pressures of the inner cavity 11 and the outer cavity 12 reach a pre-filled state in the balance, a pushing force in the direction of the outer cavity 12 is not exerted on the elastic partition 2. The inner cavity 11 and the outer cavity 12 can be inflated simultaneously through one inflation nozzle, so that the structure is reduced, and the operation is convenient. As an alternative embodiment, as shown in fig. 1 and 2, the inner chamber 11 and the outer chamber 12 are respectively connected with an air charging nozzle. When the inner cavity 11 and the outer cavity 12 adopt one charging connector at the same time, the whole charging connector is invalid when the air inlet or the air outlet is damaged, and when the charging connector is used separately, only the damaged charging connector needs to be replaced when the charging connector is damaged, so that the use cost can be reduced.
Under normal driving conditions, i.e. after inflation, the air pressure P of the outer chamber 12 t Pressure P with the inner cavity 11 n The balance is equal. When the outer cavity 1 is burst and the air pressure is releasedP t =0. The inner cavity 11 has an internal pressure P n And the tire is automatically inflated under the action of the tire until the whole tire cavity is filled. At this time, the pressure of the inner cavity 11 is P' n About 50-80% of the tire pressure is not burst, the weight of the vehicle can be supported, and the radius of the outer tire 1 is hardly changed.
Air pressure P 'of inner cavity 11 after tire burst' n Illustrated by the cross section of the figure: the total volume of the sealing chamber formed by the cover 1 and the rim 3, namely the tire chamber is V, and the volume of the outer chamber 12 formed by the elastic separator 2 and the inner wall surface of the cover 1 is V 4 The volume of the inner cavity 11 formed by the elastic separator 2 and the inner side surface of the rim 3 is V 5 . Obviously, v=v 4 +V 5 。
Tire pressure after tire burst: p'. n ＝P n *V 5 /V；
Namely: the gas pressure in the inner cavity 11 and the volume V of the inner cavity 11 after tire burst 5 Proportional to the ratio. V can be controlled according to the requirements of the vehicle model during design 5 /V＝50～80％。
According to one example of the utility model, the design parameters are: v (V) 5 V=70%. Normal tire pressure of full air: p (P) t ＝P n =240 kPa. Tire pressure after tire burst: p'. n ＝0.7*240＝168kPa。
