Description

气门嘴和带有气门嘴的车轮 技术领域
本发明涉及一气门嘴,特别涉及一气门嘴和带有气门嘴的车轮。
背景技术
气门嘴具有良好的密封性,能够防止轮胎漏气,被应用于各种车轮,并方便为车轮的轮胎填充气体,或是藉由所述气门嘴进行放气以调整胎压等。随着真空轮胎的普及,应用于真空轮胎的气门嘴和轮胎相互独立,以方便车主分别更换轮胎和气门嘴。
现有的一车轮1000P包括一轮毂100P、一轮胎300P以及一气门嘴300P,其中所述车轮1000P具有一装配通孔1001P和连通所述装配通孔1001P的一气腔1002P,所述气门嘴300P主要包括一气门芯310P和一密封主体320P,其中所述密封主体320P被设置于所述气门芯310P的出气端。所述轮胎300P被可拆卸地安装于所述轮毂100P的外壁,并在所述轮毂100P的外壁和所述轮胎300P之间形成所述气腔1002P,所述装配通孔1001P贯穿所述轮毂100P的内壁和外壁。参照图1B,在安装所述车轮1000P的过程中,需要借助工具将所述轮毂100P和所述轮胎300P分开,以在所述轮毂100P和所述轮胎300P之间形成一开口1003P,所述气门嘴300P自所述开口1003P被塞入所述气腔1002内。进一步地,所述气门嘴300P依次穿过所述轮毂100P的外壁和内壁后,被保持于所述轮毂100P的所述装配通孔1001P。
为了保障所述气门嘴300P的密封性,常见的所述气门嘴300P的所述密封主体320P的横截面沿所述气门芯310P的进气端至所述气门芯310的出气端的方向逐渐增大。所述密封主体320P的横截面尺寸小于所述装配通孔1001P的部分自所述气腔1002P穿过所述装配通孔1001P,并被保持于所述轮毂100P的内壁内侧,所述密封主体320P的横截面尺寸大于所述装配通孔1001P的部分被保持于所述轮毂100P的外壁的外侧,通过堵塞所述装配通孔1001P的方式密封所述装配通孔1001P。所述轮胎300P包裹所述轮毂100P的外壁,藉由所述气门芯310P填充气体至所述车轮1000P的所述气腔1002P,并藉由所述密封主体320P阻止气体泄漏。也就是说,现有的气门嘴300P是由所述轮胎300P内部向所述轮胎300P外部完成安装的。在实际的使用过程中,给车主造成了不少困扰。
具体来说,参照图1A和图1B,现有的所述气门嘴300P自所述车轮1000P的所述气腔1002P被安装于所述轮毂100P的所述装配通孔1001P。一旦在所述气门嘴300P使用的过程中出现故障,车主从所述车轮1000P外部无法将所述气门嘴300P和所述轮毂100P分开,需要先使用工具将所述轮毂100P和所述轮胎300P分离,在所述轮毂100P和所述轮胎300P之间形成所述开口1003P,然后从所述轮毂100P的外侧将破损的所述气门嘴300P拔出,并自所述开口1003P取出。进一步地,将新的气门嘴300P自所述开口1003P塞入所述气腔1002P后,从所述轮毂100P的外侧插入所述轮毂100P的所述装配通孔1001P,最后保持轮胎300P覆盖所述轮毂100P的外壁。不仅操作复杂,而且难度较大,通常需要专业人员使用专业的修理工具才能完成。在外行车的车主不得不通过更换整个车轮1000P的方式保持车辆正常行驶,而所述气门嘴300P损坏的所述车轮1000P只能运至修理厂进行更换气门嘴300P,这样,造成车主的修理成本增加。
