CZ277759B6 - Sectional tires with separate inner tubes and sectional tubeless tires - Google Patents

Abstract

The essence of this invention for tyres with tubes is the sectioning of the tyre by an internal flexible insert or more inserts so that an unclosed space for tubes is created along the perimeter of the tyre-casing. The flexible internal insert divides forces and, at the same time, provides reinforcement in all loading directions. The essence of this invention for tubeless tyres is a flexible internal peripheral insert mounted on the wheel rim so that together with the inter-rim it creates an independent filling space. The insert is reinforced where it is fixed to the inter-rim so that it is possible to continue driving if the filling pressure is lost without the risk of removing the tyre. Wide-surface tyres allow more inserts to be constructed in the tyre with the required number of inter-rims on the wheel.<IMAGE>

Description

The invention relates to a tire with a tube and a tubeless tire, which allows to continue driving even if the casing wall breaks through or when the pressure in the filling space drops.

Existing constructions of diagonal, radial or combination tires do not ensure sufficient maneuverability of a moving vehicle in the event of a puncture; Other solutions such as MS. No. 163 646 does not respect the problem of filling the tire reinforcement chambers.

Disadvantages are overcome by the invention, which in essence in inner tube tires is the division of the tire by an inner resilient partition or multiple partitions around the circumference of the tire so as to define open spaces for the application of the tubes. The flexible partition ensures the distribution of forces, separates the filling spaces and at the same time fulfills the function of the casing reinforcement in all directions of stress.

The essence of the tubeless tire solution is a flexible inner circumferential partition fixed in the intermediate frame so that together with the intermediate frame it creates two separate filling spaces. Valve outlets are situated in each filling space. The partition with intermediate rim assumes a guiding and springing function when both filling spaces break through. The solution allows to apply different filling pressures in each filling space, in the case of a wide-shell version it allows to reduce the construction height of the jacket. The bulkhead at the points of attachment to the intermediate rim is reinforced, which allows you to continue driving without losing the tire when the filling pressure is lost. The wide-shell design allows the construction of even more partitions inside the housing with a corresponding number of intermediate rims on the wheel.

Said solutions will increase the safety of the operation of wheeled vehicles because in the event of a puncture of one filling space the spring function takes over the other space. When both filling spaces break through, the partition provides the reinforcing and elastic function. The solution also allows to increase the utility properties of the tires such as directional stability, reduced rolling resistance, improved adhesion.

In the accompanying drawing, an exemplary embodiment of a multi-tube split tire casing is shown in cross-section in FIG. The dividing resilient partition 1 forms two open spaces 5 and 6 for two inner tubes 3 and 4 within one tire casing 2. When one of the filling spaces breaks through, the other functions assume the flexible function. When both filling spaces 5, 6 break through, the partition 1, together with the tread 8, abuts on the inner surface between the rims 7 and has an additional elastic effect. The valve outlets 8, 10 for each tube are led separately on the rim periphery side by side or opposite.

In the accompanying drawing, FIG. 2 shows an exemplary embodiment of a tubeless split tire in cross-section. The partitioning flexible inner partition 1, which is provided in the intermediate rim 12, forms the filling tubeless spaces 5 and 6 within one tire casing 2. If one of the filling spaces breaks through, the other filling function assumes the elastic function. When both filling spaces 5, 6 break through, the tread 8 engages the thickened part of the partition 11 and thus forms a full flexible tire on the vehicle wheel. The valve outlets 9, 10 are led for each filling space on the rim circumference 7.

Separating resilient partitions within the housing are built-in during its construction or additionally by gluing, or by welding or vulcanizing. Tubes for tubeless split tires have a welded-on or cast intermediate rim, which serves to fit the partition and has valve outlets for each filling space. The rims for multi-tube split tires are perforated for valve outlets, they do not require any other modifications compared to classic types. For wide-walled tires, multiple flexible inner bulkheads can be constructed within a single tire using the appropriate number of intermediate rims and valve outlets.

The tires and trim rims of the invention can be used for all wheeled vehicles. Their assembly and disassembly is feasible by common technological equipment. The filling spaces are alternately pressurized to the desired pressure in order to avoid stressing the partition.
