Abstract

一種可自我修補破洞的充氣輪胎，可利用儲存在輪胎中的補胎劑來修補破洞。

Description

自補胎
本發明係關於一種可自動修補破洞的輪胎，特別是關於一種利用儲存在輪胎中的補胎劑來修補破洞的充氣輪胎。
現今的自補胎，多是在充氣輪胎的胎面內層塗上一層黏稠的補胎劑，或是在胎面的內面設置一層封閉的補胎劑層，在胎面發生破洞並穿過補胎劑層時，令補胎劑從破洞溢出，並填滿破洞，防止輪胎漏氣。此種自補胎的缺點在於發生破洞後補胎劑無法重新填充，多餘的補胎劑也無法回收使用，並且大多必須在輪胎工廠內製作，以至於造價偏高。
因此，如何設計一種自補胎，不需要高成本來製作，且又不需要在工廠內利用特殊製程製作，甚至可以利用現有的一般充氣輪胎改裝成自補胎，且破洞後輪胎可以利用現有技術修補，補胎劑也可以再充填或再回收利用，則可以大大降低目前的成本，使自補胎的安裝及後續的維修更容易，使自補胎更容易普及。
有鑑於上述課題，本發明之目的為提供一種易於改裝及修復的自補胎，以降低整個自補胎的製造及維護成本。
於一實施例，請參考圖1，依據本發明之一種自補胎中，具有一氣密的外胎及輪圈，一可充氣的內胎，及一個位於內、外胎之間的補胎劑層，該外胎可由一氣嘴將液態補胎劑注入內、外胎之間的補胎劑層，該內胎可由一氣嘴將內胎充氣，正常使用時補胎劑受內胎氣壓擠壓，會均勻分布於外胎內面的補胎劑層，且其液壓會與內胎內的氣壓相同，外胎有破洞時補胎劑會受內胎擠壓由破洞擠出，因而接觸空氣並填補破洞，內、 外胎同時被穿破時，補胎劑仍會因漏氣處較低的氣壓而流向破洞，因而填補破洞，阻止漏氣。
於另一實施例，請參考圖2，依據本發明之一種自補胎，與前例類似，但在內外胎之間的補胎劑層更具有一隔間構造，以便在內外胎之間隔出一層空間作為補胎劑層，供補胎劑儲存與流動，同時讓補胎劑可以均勻分布於所要保護的胎面或胎壁內面，該隔間構造可為獨立的構造，或是貼附於內胎表面或外胎內面。
於另一實施例，請參考圖3，依據本發明之一種自補胎中，與前例類似，但是內胎與外胎的氣嘴合在一起變成一個二合一氣嘴，由輪圈上的一個氣嘴孔伸出，該二合一氣嘴的一個實施例包含兩個氣閥及兩個氣道，其中一個氣閥與一個氣道可對內胎充氣，另一個氣閥與另一個氣道則可對內、外胎間的補胎劑層注入補胎劑，或是該二合一氣嘴的另一個實施例包含一個共用氣閥、兩個氣道及一個氣道選擇開關，成為一個可選擇氣道的氣嘴，靠氣道選擇開關來選擇對內胎充氣或是對內、外胎間的補胎劑層注入補胎劑，本二合一氣嘴可以適用於市面上大部分僅有單一氣嘴孔之輪圈，並可將現存之傳統無內胎輪胎改造成本發明之自補胎。
承上所述，本發明係將一個內胎置於原本無內胎的充氣輪胎內，在內、外胎間的空間注入補胎劑，成為一個自補胎，不僅安裝成本較低，並且維護容易，任何現有的傳統充氣輪胎皆可以改裝成自補胎，破洞發生後內胎或外胎皆可以拆卸，並可分別用現有的補胎技術修補，且輪胎內的補胎劑還可以從氣嘴回收或再充填，因此與其他種類的自補胎比較，本發明具有低成本、維護容易、可直接由現有之傳統輪胎改裝的優點。

圖5為本發明之另一種二合一氣嘴。
以下將參照相關圖式，說明本發明複數實施例之一種自補胎，其中相同元件以相同符號表示。
如圖1所示，為本發明之第一實施例之自補胎，係包含輪圈1、氣密的外胎2、外胎氣嘴(可稱為第一氣嘴)3、外胎氣道4、可充氣的內胎5、內胎氣嘴(可稱為第二氣嘴)6、內胎氣道7及位於內、外胎之間的補胎劑層8。輪圈1具有第一氣嘴孔(外胎氣嘴3穿過輪圈1之處的開孔)與一第二氣嘴孔(內胎氣嘴6穿過輪圈1之處的開孔)。外胎2安裝於輪圈1上，內胎5安裝於外胎2內與輪圈1之間。外胎氣嘴3由前述的第一氣嘴孔伸出，而內胎氣嘴6則由前述的第二氣嘴孔伸出。外胎氣道4位於外胎氣嘴3內，並與內胎5、外胎2之間的空間相通。內胎氣道7位於內胎氣嘴6內，並與內胎5內部相通。外胎氣嘴(可稱為第一氣嘴)3內更包含一外胎氣閥(未繪示)，其與外胎氣道4相接，而內胎氣嘴(可稱為第二氣嘴)6內更包含一內胎氣閥(未繪示)，其與內胎氣道7相接。補胎劑層8用以儲存由外胎氣道4注入之補胎劑。內胎5經由內胎氣嘴6及內胎氣道7充氣後，補胎劑由外胎氣嘴3及外胎氣道4注入到內胎與外胎間的補胎劑層8。正常使用時，補胎劑受內胎5中的氣壓擠壓，會均勻分布於外胎2內面的補胎劑層8，且其液壓會與內胎5內的氣壓相同。在外胎2發生破洞時，補胎劑即會受內胎擠壓由破洞流出，因而接觸空氣填補破洞並防止漏氣。內胎5及外胎2同時被穿破時，補胎劑仍會因漏氣處較低的氣壓而流向破洞，因而填補破洞，阻止漏氣。
如圖2所示，為本發明之第二實施例之自補胎，與前例類似，但與第一實施例不同處在於內、外胎之間多了一層隔間構造9，可在內胎5及外胎2之間隔出一層空間做為補胎劑層8，以便儲存補胎劑，並供補胎劑流動，讓補胎劑可以均勻分布於所要保護的胎面或胎壁內面。隔間構造9具有凸起的結構藉以控制補胎劑在輪胎內的分布區域。該隔間構造9可貼附於內胎5的外表面，或貼附於外胎2的內表面，或為一獨立於內胎5 與外胎2的構造物。
如圖3所示，為本發明第三實施例的自補胎，與前例類似，但與前例不同的地方在於本實施例將前例的內胎氣嘴6與外胎氣嘴3合而為一，成為一個二合一氣嘴10，由輪圈1上的一個氣嘴孔(如圖3中的二合一氣嘴10穿過輪圈1的開孔)伸出。輪圈1上僅需要一個氣嘴孔即可安裝二合一氣嘴10。外胎氣道4及內胎氣道7均位於二合一氣嘴10內，其中內胎氣道7與內胎5相通，外胎氣道4與外胎2內層(即內胎5與外胎2之間的空間)相通，達到使用一個氣嘴即可分別對內胎5充氣及對位於內胎5、外胎2之間的補胎劑層8注入補胎劑的目的。本實施例的二合一氣嘴10可以適用於市面上大部分僅有單一氣嘴孔之輪圈1，並可將現存之傳統無內胎輪胎改造成本發明之自補胎。
如圖4所示，為一種二合一氣嘴的實施例，二合一氣嘴11包含兩個氣閥(外胎氣閥111、內胎氣閥112)及兩個氣道(外胎氣道4、內胎氣道7)，內胎氣道7與內胎5相接，外胎氣道4與內、外胎間的補胎劑層8相接。其中，內胎氣閥112與內胎氣道7可對內胎5充氣，而外胎氣閥111與外胎氣道4則可對內胎5及外胎2間的補胎劑層8注入補胎劑。本實施例的二合一氣嘴11可以適用於市面上大部分僅有單一氣嘴孔之輪圈1，並可將現存之傳統無內胎輪胎改造成本發明之自補胎。
如圖5所示，為另一種二合一氣嘴的實施例，二合一氣嘴12包含一個共用氣閥121與兩個氣道(外胎氣道4、內胎氣道7)及一個氣道選擇開關122，成為一個可選擇氣道的氣嘴。內胎氣道7與內胎5相接，外胎氣道4與內、外胎間的補胎劑層8相接，由氣道選擇開關122選擇共用氣閥121要與外胎氣道4及內胎氣道7中的哪一個氣道相接，以選擇對內胎5充氣或是對位於內胎5及外胎2之間的補胎劑層8注入補胎劑。本實施例的二合一氣嘴12可以適用於市面上大部分僅有單一氣嘴孔之輪圈1，並可將現存之傳統無內胎輪胎改造成本發明之自補胎。
承上所述，本發明之自補胎在原本無內胎的充氣外胎內增加一個內胎，並利用外胎氣道將補胎劑注入內、外胎之間，具有低成本、易維護以及可利用現有傳統輪胎改裝等優點。
以上所述僅為舉例性，而非為限制性者。任何未脫離本發明之精神與範疇，而對其進行之等效修改或變更，均應包括於後附之申請專利範圍中。
