Abstract

A vehicle tyre comprises a tread carrying member 1 and an inner, wheel engaging member 2. A number of resilient support members 3 formed of a nylon material extend between the inner member 2 and the tread member 1. The support members 3 are fixed to the tread member 1 and inner member 2 by way of T-shaped protrusions which engage with T- shaped sockets on the tread member 1 and the inner member 2 respectively. <IMAGE>

Description

SPECIFICATION Vehicle tyre This invention relates to a vehicle tyre.
Conventional tyres for use on road vehicles and on the landing gear of aircraft are generally air filled. This allows tyres to provide support for the vehicle whilst also providing the tyre with a degree of resilience to allow it to ride effectively over ground irregularities. Such tyres have a number of disadvantages however. It is necessary to check the air pressure in the tyre periodically to ensure that the tyre is always inflated to the pressure which provides the best performance characteristics.
The tyres can also be punctured by sharp objects such as nails, broken glass and the like, thus rendering the tyre useless until repaired.
Sudden deflation of a tyre when a vehicle is in motion can often be dangerous as it may cause the vehicle to slew sharply to one side.
According to the present invention there is provided a vehicle tyre comprising a substantially circular ground engaging tread member for fitment to a wheel member and being spaced apart from said wheel member by a plurality of resilient material support members.
Preferably, the support members are of annular form. preferably also, the support members are evenly spaced around the circumference of the wheel member.
Preferably also, the annular support members are arranged so that the outer surface of each support member engages the surface of the two circumferentially adjacent support members.
Preferably also, an inner circular member is provided for fitment directly to the wheel member, the annular support members extending between the inner circular member and the tread member.
Preferably also, the annular support members are fixed to the tread member and to the inner circular member.
Most preferably the annular support members are fixed to the tread member and the inner circular member by way of T shaped protrusions on the annular support members engaging with T shaped sockets on the tread member and the inner circular member.
Preferably also the annular support members are formed from a plastics material.
Preferably also, the tread member is formed from a plastics material.
Embodiments of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which: Fig. 1 is a sectional side view of a vehicle tyre made in accordance with the present invention; Fig. 2 is a detail view, to a larger scale, of part of the vehicle tyre of Fig. 1; and Figs. 3 and 4 are further sectional side views of the vehicle tyre of Fig. 1.
Referring to the drawings, a vehicle tyre comprises a casing member which includes an outer, tread carrying member 1 and an inner, wheel engaging member 2. A number of radial support members 3 extend between the inner member 2 and the tread member 1.
The support members 3 are formed of a resilient plastics material, for example, a nylon material and in the embodiment shown are hoops which are circular in cross-section.
Other shapes of support members may be used in different applications.
The support members 3 are fixed to the inner surface 10 of the tread member 1 and the outer surface 20 of the inner member 2 by way of T-shaped protrusions 4a and 4b on the support members 3 which engage with Tshaped sockets 5a and 5b on the tread member 1 and the inner member 2 respectively.
The tread member 1 is formed from a nylon material with a tensile strength of 11,000 psi.
Alternatively the tread member 1 may be formed from an acetal material.
The T-shaped protrusions 4a and 4b may be either separate members which are fixed to the surface of the support members 3 by appropriate means or they may be integrally moulded parts of the support members 3.
The tyre assembly may be fitted to a wheel rim in use in a similar manner to conventional tyres or if desired other appropriate fixing means may be used.
In use the resilient nature of the support members 3 provides support for the weight of a vehicle to which the tyre assembly is attached. The support members 3 are arranged closely together circumferentially around the tyre. Thus, as can be best seen in Fig. 3, the support members 3 at the bottom of the tyre assembly deform under the effects of the weight of the vehicle and press against the adjacent support members thus distributing the weight around the support members 3.
Similarly, as can be seen in Fig. 4, the Tshaped protrusions 4a and 4b and T-shaped sockets 5a and 5b allow the support members 3 at the top of the tyre assembly to support some of the weight of the vehicle under tension.
The tyre has the advantage over conventional tyres that, as it does not contain compressed air, it does not need such regular checking and does not lose its support suddenly if the tread member 1 is punctured. It is only necessary to inspect the tread member 1 occasionally for any evidence of extensive damage.
The tyre can be made in different sizes and strengths to allow it to be used on many different road vehicles and on the landing gear of aircraft.
The size and number of support members 3 in each tyre can be varied to give different tyres various different support characteristics.
Modifications and improvements may be made without departing from the scope of the invention.
