Description

Pneumatic tires with variable cross-section and barrel v / srk to accommodate the pneumatic tire

The invention relates to a pneumatic tire with a variable cross-section and a drive for receiving this pneumatic tire for use on different roadways, under different load conditions and different operational requirements, in particular for agricultural vehicles.

There are vehicles which are equipped with low-pressure tires and which have an internal pressure control system. With these drives, an adaptation to the respective application conditions in terms of transport is achieved. The problem or the functional intention, e.g. 3. leveling when plowing in the groove, the tire width adjustment in agricultural lieihenkulturen or the change in the traction capability as a function c ¹ he floor or road conditions is not achieved with the known solutions.

The purpose of the invention is to make the use of vehicles, especially tractors in agriculture, more universally applicable by procuring suitable hoops and associated drives The invention is based on the object of creating a pneumatic tire with a corresponding drive which has a stepless, "or more w ^ it ^ hoii.Te". ^T ^ rä; i: lorung his ^ It also allows for cutting during the journey or during the journey, and thus continuously variable shape and size of the contact area, which can be changed through it, overpressing and rolling half-meter.
