Tire for use in vehicle, has carcass type reinforcement structure with end axially inside with respect to radial virtual axis passing through geometric centre of control rod of tire bead which extends outside in form of flanges

摘要

#CMT# #/CMT# The tire has carcass type reinforcement structures (10, 20) anchored on each side of a tire in a tire bead. The beads have a control rod (7) and an anchoring mixture (40), where each bead extends outside in the form of flanges (6) which join a tire tread. Each flange is reinforced by a flange insert (30) and has a rubber supporting a load. The structure (10) has a ply turn up (11) around the rod and a turned portion (12) axially outside the rod. The structure (20) has an end (21) axially inside with respect to radial virtual axis passing through a geometric centre (C) of the rod. #CMT#USE : #/CMT# Used in a vehicle (claimed). #CMT#ADVANTAGE : #/CMT# The end of the reinforcement structure is axially inside with respect to the radial virtual axis passing through the geometric centre of the rod, thus permitting to ensure resistance characteristics to external impacts and facilitating mounting of the tire, while facilitating better resistance to damage and ensuring better performance in unfavorable conditions. The reinforcement structure confers optimal protection of an inner zone against impact and fatigue. The arrangement of the turned portion permits to optimize pneumatic characteristics and fabrication characteristics. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a radial sectional view showing a tire bead and a flange.
