Non pneumatic tire for use in motor vehicle wheel, has tire ribs cooperating with pockets introducing damping in case of deformation of ribs, where pockets are formed of walls delimiting volume filled with compressible material

摘要

The tire has a deformable structure (3) comprising tire ribs (30) extending transversally along the width of the tire. The ribs cooperate with pockets that introduce damping in case of deformation of the ribs. The pockets are filled with a damping material and are connected to the ribs. Each pocket is placed at the center of a recess (31). The pockets are formed of walls (60) delimiting a volume filled with a compressible material e.g. expanded polyurethane. Outer parts of the walls of the pockets are connected to walls delimiting the recesses.
