Device for regulating tyre properties and vehicle tyre

摘要

Pneumatic tire for agricultural and other vehicles has air cavity divided round the tire into individual chambers connected to each other via throttle apertures. The tire has its air cavity divided by radial partition walls (10) into individual chambers connected to each other via throttle apertures (12). The throttle apertures (12) are in the partition walls. The air cavity may be filled with a foam or cellular structure with limited air passage capacity. On rough ground, air is forced from the chamber in contact with the ground into the other cavities, producing the effect of a soft ride. On the road, when the pressure in the chambers is more uniform, a harder ride effect is produced.
