Abstract
一種軌道車輛碟式煞車墊片具有一基板;若干個支撐板配裝於該基板;及若干個磨擦構件固定於該等支撐板。該基板具有若干個穿孔引出部份,其各有一凸出部於上有一各別的支撐板直接地定置,而在該基板和該支撐板之間形成一間隙。
Description
本發明係有關於一種軌道車輛碟式煞車墊片。
如所知,碟式煞車器會受到嚴重的應力,且最佳的煞車有賴於該制動力被有效地傳送至該碟式墊片。
近來,相對於單用一個大的,趨勢已朝向具有若干個小磨擦構件的墊片。在此一方案中,各個墊片包含一主承壓板;若干個支撐板固定於該主板;及若干個磨擦構件個別或成對地固定於各別的支撐板。
為確保該等磨擦構件的有效冷卻,DE 10043528專利描述並請求一種方案,其中各別的間隔物係被插入該等支撐板與它們所固定的主板之間。該等間隔物會在該等支撐板與該主板之間形成一間隙,俾得以通風並冷卻該等磨擦構件。
每個間隔物皆有一中孔,其在組合的墊片上會被一鉚釘接合以將該支撐板固定於該主板。
雖在通風該等磨擦構件的底面是成功的,但在DE 10043528專利中所述並請求的間隔物無可避免地會增加組合的零件數目,而增加組合時間和該墊片的整體重
量。特別是,該墊片的重量增加,會增加密封物上的磨損及煞車時的噪音標度。
因此覺得需要一種方案,可以藉其來形成一通風隙以冷卻該等磨擦構件,但不會招致習知技術的缺點。
依據本發明,係提供一種軌道車輛碟式煞車墊片具有請求項1中所示的必要特徵,及在請求項2~4中所示的較佳及/或輔助特徵。

2‧‧‧穿孔引出部份

3‧‧‧凸出部
4‧‧‧中孔

本發明之一非限制性實施例將會參照所附圖式,純作為舉例來被描述,其中:圖1示出依據本發明的墊片之一基板的平面圖;圖2示出沿圖1之基板的II-II線之一截面;圖3示出依據本發明的墊片之一部份透視平面圖;圖4示出沿圖3中的IV-IV線之一截面。
圖1中的編號1表示依據本發明的碟式煞車墊片之一基板整體。
基板1包含若干個圓形穿孔引出部份2等排列成組群2a,各包含三個穿孔引出部份2排列成一三角形的形式。
如圖2中更清楚地示出,各穿孔引出部份2包含一圓形凸出部3具有一中孔4被一截頭錐狀壁界定。在實際使用時,孔4會被一鉚釘接合以將一支撐板固定於基板1,如
後所述。
圖3中的編號5表示一依據本發明的軌道車輛碟式煞車墊片整體。
墊片5包含基板1;五個三角形磨擦構件6,各固定於一各別的支撐板7(示於圖4中);及若干個鉚釘8用以將支撐板7固定於基板1。更具言之,每個支撐板7係被三個以一三角形形式排列的鉚釘8固定於基板1。
如圖4中所示,為將各支撐板固定於該基板,各鉚釘8會接合各別的穿孔引出部份2中之中孔4,及一形成於支撐板7中的孔6a。顯然地,各支撐板7皆具有三個孔6a排列成一三角形的形式。
當墊片5被組合後,鉚釘8會固定直接地接觸穿孔引出部份2之圓形凸出部3的相關支撐板7。換言之,圓形凸出部3會支撐著與該基板1的其餘表面分開的支撐板7,故會在該基板1與各支撐板7之間形成一間隙9,而可在其中通風並有效地冷卻磨擦構件6。
相較於DE 10043528專利中的方案,依據本發明的方案可減少該墊片整體的重量,故會減少密封物上的磨損和噪音標度。於此相關方面,很重要的是要注意依據本發明的墊片如何容許使用較短的鉚釘,而得減少整體重量。
又,用以組合的零件數目亦會減少,故在產能和成本方面具有顯著的優勢。
最後,依據本發明的墊片係更可適調的,故會改良磨擦,並因而改良煞車效率。
