Wheel for a vehicle including enclosed hollow foam member
Abstract:
The invention relates to a novel wheel which serves for equipping with a pneumatic tire and essentially realizes two apparently incompatible properties of solid rubber tires and pneumatic tires, namely strength and good shock absorption, in a single wheel. This wheel is distinguished by the fact that it has a toroidal hollow foam member enclosed by the pneumatic tire and comprising reversibly deformable material having a large number of enclosed cavities serving for the absorption of gas. The substantial advantage of the tire according to the invention is obvious. Damage to the tire skin by a stone or nail does not in fact inevitably lead to an immediate and complete loss of air, as is often the case with known tires. Thus, the toroidal hollow foam member can itself store air in its cells, which not only permits continued riding for a certain time but also reduces the risk of accidents in the event of damage to the tire. Further advantages of the tire according to the invention are that the sound-insulating properties of the foam reduce the running noises of the wheel and that the foam torus optionally enclosed in an inner tube is hollow inside, which simplifies the removal of the pneumatic tire from the rim.
