Abstract
Description
本發明係關於一種自行車心軸及自行車心軸組。 The invention relates to a bicycle spindle and a bicycle spindle group.
一般自行車的輪轂軸,係穿過一輪轂並鎖配於自行車之車架上(如前叉或後叉),可透過一工具而旋轉該輪轂軸鎖固夾緊該輪轂於該前叉或後叉之二叉部之間。 Generally, the hub axle of a bicycle passes through a hub and is locked on the bicycle frame (such as a front fork or a rear fork). The hub axle can be rotated by a tool to lock and clamp the hub on the front fork or rear. Between the two forks.
然而,一般市面上的貫通心軸的規格五花八門,其尺寸(如長度)也有所不同。因此通常需要依照車架組的設計選擇適用的貫通心軸,若規格有差異,例如貫通心軸的長度太長在裝配時,貫通心軸之軸首與該前叉或後叉一外側之間會露出一大段,使該貫通心軸無法迫壓該前叉或後叉之二叉部夾緊輪轂。因而需要根據不同的車架組購買符合規格的貫通心軸,而有成本較高的問題。 However, the specifications of through mandrels generally available on the market are varied, and their dimensions (such as length) are also different. Therefore, it is usually necessary to select the applicable through mandrel according to the design of the frame group. If there are differences in specifications, for example, the length of the through mandrel is too long. During assembly, the shaft head of the through mandrel and the outer side of the front fork or rear fork A large section will be exposed, so that the through spindle cannot press the front fork or the second fork of the rear fork to clamp the hub. Therefore, it is necessary to purchase through mandrels that meet the specifications according to different frame groups, which has the problem of higher cost.
因此,有必要提供一種新穎且具有進步性之自行車心軸及自行車心軸組,以解決上述之問題。 Therefore, it is necessary to provide a novel and progressive bicycle spindle and bicycle spindle assembly to solve the above-mentioned problems.
