摘要

現今自行車為各國所提倡的環保交通工具，而騎士的安全重要性為我們機構設計者之考量目標，因此自行車煞車裝置應講求高機能和高強度的制動能力，為了能確保在急速煞車時能安全停止，本文主要提出自行車機械式碟煞卡鉗之機構創新設計，利用有限元素分析軟體來分析撥扳機構之等效應力、變形量及安全係數，同時將碟煞卡鉗的設計藍圖製作成實體化並進行碟煞盤變形量測試。由於市售的自行車碟煞卡鉗，煞車時蹄片作動方式大多為單邊浮動，因此會造成碟煞盤受力不均勻產生變形，而本文設計出一組撥扳機構裝置於機械卡鉗裡面，當騎士煞車時，推桿推動槓桿機構，使得機構帶動蹄片，同步對碟煞盤產生摩擦，不僅達到高制動力的效果，且提高碟煞盤的使用壽命，同時追求完善的產品品質以及提高自行車市場的競爭力。

Today bike is various countries to advocate environmental transport, and institutions designers of rider security by consider target. Bike brake device should emphasize high function and high strength of brake ability that can ensure in rapid brake for security stopped. This paper proposed bike machinery type disc brake calipers of institutions innovation design that uses finite element analysis software to analyze the dial trigger mechanism effective stress, deformation and safety factor, while the disc brake caliper blueprints made into materialized and make disc brake disc deformation tests. Because commercially available bicycle disc brake calipers, brake shoe set tablets for moving way mostly for unilateral floating. It can caused disc brake by uneven force to make disc brake deformation. The paper design a group dial trigger device to machinery calipers inside. When the rider brake, putter promoting lever institutions, makes institutions led shoes, and produces disc brake friction. It is not only reached high power system power but also improve disc brake using life. While can pursuit perfect of products quality and improve competitiveness of bike market.
