摘要:
Afin de maintenir un pneumatique (10) en état de fonctionnement après son dégonflement, on incorpore une structure combinée (34) à l'intérieur de la partie de couronne (22) du pneu (10) pour qu'il résiste aux forces de compression qui apparaissent lorsque le pneu (10) est dégonflé. La structure combinée (34) comporte un élément enroulé précontraint (36) placé adjacent à des segments de bandes espacées coaxialement (37). Le pneu (10) présente des plis radiaux (32) qui sont destinés à transmettre les forces de compression de la zone de contact avec le sol à la structure combinée (34), laquelle résiste ainsi efficacement aux forces de compression .

The invention relates to a run-flat support body for run-flat vehicle wheels. Said support body is typically embodied as a shell-shaped, metallic annular body (3) having an undulated supporting annular surface. The invention relates to a simple, effective method for producing one such annular body (3), according to which a rectangular blank (6) which is cut out of a strip of sheet metal is bent along the longitudinal side to form a ring and the open ends of the ring are interconnected by a material connection. The annular blank (7) thus produced is provided with the desired profile according to the pressure-rolling method, is provided with connecting elements (9), and cut open between the same.
摘要:
Bei einem gasgefüllten Fahrzeugreifen sind zum Zwecke der Verminderung der Schallabstrahlung mit dem Reifen kraft-und momentschlüssig verbundene Schwingungsabsorber (4) vorgesehen. Die Schwingungsabsorber sind vorzugsweise im Reifeninneren angebracht, können jedoch auch an den äußeren Seitenflächen der Reifen befestigt sein. Die Schwingungsabsorber können im Querschnitt beispielsweise dreieckförmig, rohrförmig oder sichelförmig ausgebildet sein.

摘要:
A run-flat tire-wheel assembly having, in an inside cavity of the tire/rim, a run-flat support formed by a ring-shaped metal shell and rubber elastic members wherein the contact surfaces of the ring-shaped metal shell and the rubber elastic members are coated with an organic solvent-based adhesive, whereby the bondability between the ring-shaped metal shell and rubber elastic members is improved.
摘要:
@ A run-flat pneumatic radial tire is equipped with a prestressed helical coil (36) which is positioned inside the tire crown (22) radially inwardly of the tread (20) thereof. The coil is wound to approximately 50 percent of its free diameter to prestress it and the outer surface has a resin-impregnated tape (60) applied thereto. The tape serves to hold the coil in a predetermined condition while the taped coil is cured (62). The taped coil can be co-cured in situ with the tire or prepared in advance of tire fabrication.
摘要:
Provided are a run-flat supporting body whose durability is enhanced while a large number of through holes are formed in an annular shell thereof, and a tire/wheel assembly. The run-flat supporting body (1) is configured of the annular shell (2) and elastic rings (3) and (3). The annular shell (2) works as a supporting surface on an outer peripheral side, and bifurcates into two leg portions on an inner peripheral side. In addition, the annular shell (2) is provided with a large number of the through holes (4) in wall surfaces thereof . The elastic rings (3) and (3) are attached respectively to the two leg portions of the annular shell (2). The run-flat supporting body 1 is supported on a rim of a wheel with the elastic rings (3) and (3). According to a configuration of the present invention, peripheries of the respective through holes (4) are thickened, residual stresses are applied to the peripheries of the respective through holes (4), or each through hole (4) is formed into an elliptic shape having the major axis in a circumferential direction.
