<p>#CMT# #/CMT# The device has an annular support structure divided into ring sectors (32), where each sector has a protection portion made of rigid rubber. The sectors are connected between them by male and female connection units. The female connection unit (35) is formed of a light having lower and upper radial zones (35a, 35b) with axial width higher and lower than a tab, respectively. The zone (35a) presses the tab. The zone (35b) receives a rod by axial blocking in an anchoring position of the tab due to rising of one sector incorporating the tab with respect to the sector incorporating the light. #CMT#USE : #/CMT# Running flat device for equipping an installed assembly (claimed) for a motor vehicle e.g. military vehicle that is utilized to evolve on all types of ground such as sandy ground. #CMT#ADVANTAGE : #/CMT# The running flat device is traveled to significant distance at relatively high speed when the installed assembly is partially or completely deflated. The device provides improved compressive strength at reduced inflation pressure. The utilization of the protection portion protects an external radial face of the annular support structure and two lateral faces of the structure, and protects a cover of the rolling tire in an inflated state during the time of an impact in the event of contact of the device with sides or top of the cover. The utilization of the connection units minimizes the axial displacement of the sectors and distributes the efforts on the adjacent sectors in the event of lateral impact on an end of the sectors. The device provides improved axial flexibility during the lateral impact applied to the installed assembly, and equips the installed assembly without utilizing an air chamber. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial perspective view of male and female connection units whose two circumferential ends are provided with a ring sector of a running flat. 32 : Ring sectors 32a, 32b : Rigid support elements 32c : Elastic layer 35 : Female connection unit 35a, 35b : Lower and upper radial zones #CMT#POLYMERS : #/CMT# Annular spacer are mounted in contact with lateral faces of the support structure and are made of rubber.</p> |
