<p>#CMT# #/CMT# The device has a cross-linked and expanded puncture-resistant annular support (30) mounted between a wheel rim (10) and a tire (20) of a non-pneumatic mounted assembly (1) to support the tire. The support is formed of a closed cellular type cross-linked rubber composition. The composition includes reinforcing inorganic filler, organic blowing agent and polyamide based structural reinforcement textile fibers. The active grade zinc oxide in the composition activates thermal decomposition of the agent to stabilize expansion of the support by giving a minimized average density to the support. #CMT# : #/CMT# An independent claim is also included for a non-pneumatic mounted assembly of a two-wheeled vehicle such as bicycle, comprising a puncture-resistant device. #CMT#USE : #/CMT# Puncture-resistant device for a non-pneumatic mounted assembly of a two-wheeled vehicle e.g. bicycle (all claimed) #CMT#ADVANTAGE : #/CMT# The active grade zinc oxide in the composition activates the thermal decomposition of the agent to stabilize the expansion of the support by giving the minimized average density to the support, thus obtaining improved dynamic performances of the cross-linked and expanded support with minimized rolling resistance, and hence increasing the service life of the support. The device provides effective protection against the risks of puncture of the tire by perforation, impact/pinching or vandalism. The device ensures bearing and rolling of the vehicle under satisfactory conditions, while reducing the weight of the non-pneumatic mounted assembly. The device maintains constant rolling resistance at a low level, and ensures satisfactory comfort, road-holding and service-life qualities for a user. The support can be mounted easily inside the tire, without requiring specific tool other than standard tire levers. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic axial half-sectional view of a non-pneumatic mounted assembly for a bicycle, in which a support does not follow a base of a rim. 1 : Non-pneumatic mounted assembly 10 : Wheel rim 11, 12 : Flanges 20 : Tire 30 : Cross-linked and expanded puncture-resistant annular support #CMT#POLYMERS : #/CMT# The composition is based on elastomer that is selected from a group comprising ethylene-propylene copolymer, ethylene-propylene-diene terpolymer, natural rubber, polyisoprene, nitrile rubber, polybutadiene and styrene-butadiene copolymer.</p> |
