Title (EN) NON-PNEUMATIC TIRE OF DOUBLE-DENSITY COMPOSITE POLYMER MATERIAL
(FR) PNEU NON PNEUMATIQUE DE MATÉRIAU POLYMÈRE COMPOSITE À DOUBLE DENSITÉ
(ZH) 一种双密度复合高分子材料免充气轮胎
Abstract:
(EN) Disclosed is a non-pneumatic tire of a double-density composite polymer material, the tire comprising a tire body (1) and a tread layer (2) provided on an outer circumference of the tire body (1), wherein the tire body (1) is of a PU foam solid structure, and the tread layer (2) is of a polyurethane elastomer structure with a density different from that of the tire body (1), and is integrally formed with the tire body (1) by means of bonding. By means of the above-mentioned structure, the non-pneumatic tire of a double-density composite polymer material has a good shock-absorbing effect, brake safety, and abrasion resistance, but does not build up heat, and has a colourful and bright appearance, is fluorescent at night, and is safer.
(FR) L'invention concerne un pneu non pneumatique d'un matériau polymère composite à double densité, le pneu comprenant un corps de pneu (1) et une couche de bande de roulement (2) disposée sur une circonférence externe du corps de pneu (1), le corps de pneu (1) présentant une structure solide de mousse de PU, et la couche de bande de roulement (2) étant composée d'une structure élastomère de polyuréthane présentant une densité différente de celle du corps de pneu (1) et étant formée d'un seul tenant avec le corps de pneu (1) au moyen d'une liaison. Au moyen de la structure susmentionnée, le pneu non pneumatique composé d'un matériau polymère composite à double densité présente un bon effet d'amortissement des chocs, une bonne sécurité du frein et une bonne résistance à l'abrasion, mais n'accumule pas de chaleur et présente un aspect coloré et brillant, est fluorescent la nuit et est plus sûr.
(ZH) 一种双密度复合高分子材料免充气轮胎,包括有轮胎本体(1)和设置于轮胎本体(1)外侧周沿的胎面层(2),轮胎本体(1)为PU发泡体实心结构,胎面层(2)为聚氨酯弹性体结构,密度不同于轮胎本体(1),且与轮胎本体(1)粘结形成一整体。通过上述结构,双密度复合高分子材料免充气轮胎吸震效果好,刹车安全,耐磨却不生热,外观色彩多样亮丽,夜晚荧光,更安全。
