Description
本發明係有關一種電動自行車電動補助力之諧波齒輪傳動機構,尤指一種可以達到電動自行車之諧波動力傳遞減速效果的電動自行車補助力傳動技術。 The invention relates to a harmonic gear transmission mechanism of electric auxiliary power of an electric bicycle, in particular to an electric bicycle auxiliary power transmission technology which can achieve the effect of reducing the harmonic power transmission and deceleration of the electric bicycle.
按,自行車不僅是一般的交通工具而已,甚至已經發展成為休閒娛樂與運動競賽中不可或缺的複合式運動休閒工具。尤其是,加裝電動馬達的電動輔助自行車確實可以有效減少騎乘者的體能負擔,所以電動輔助自行車儼然已經受到廣大消費者的青睞與喜愛。一般來說,電動輔助自行車的馬達傳動機構係安裝於自行車的前、後輪轂內或銜接自行車之輸出軸而與大齒盤連動,用以提供驅動前輪或後輪旋轉的補助動力。 According to the press, bicycles are not only general means of transportation, they have even developed into indispensable compound sports and leisure tools in recreation and sports competitions. In particular, electric assisted bicycles equipped with electric motors can effectively reduce the physical burden of riders, so electric assisted bicycles have been favored and loved by consumers. Generally speaking, the motor transmission mechanism of the electric auxiliary bicycle is installed in the front and rear wheel hubs of the bicycle or connects with the output shaft of the bicycle and is connected with the large gear plate to provide auxiliary power for driving the front or rear wheels to rotate.
依據所知,具備補助力傳動功能的自行車代表性專利如新型第M484555號『具單向功能的自行車助力馬達』專利所示。該專利包含一可轉動的外殼、一設於外殼內的馬達機構以及複數傳動於外殼與馬達機構輸出軸之間的齒輪組,藉此馬達機構的動力依序由輸出軸、齒輪傳遞動力至外殼。該專利雖然具備補助動力的輸出功能;惟,該專利之機構設置非為諧波齒輪傳動機構,故無法產生諧波動力的傳動效果,以致會有動力減速效果不佳、體積較大、重量較重以及傳動平穩度不佳等缺失產生,因而 不符合自行車領域的輕量化趨勢。 According to what is known, representative patents for bicycles with auxiliary power transmission functions are shown in the new patent No. M484555 "Bike Booster Motors with One-way Function". The patent includes a rotatable housing, a motor mechanism provided in the housing, and a gear set that is transmitted between the housing and the output shaft of the motor mechanism, whereby the power of the motor mechanism is sequentially transmitted from the output shaft and gear to the housing . Although the patent has the output function of subsidizing power; however, the mechanism of this patent is not a harmonic gear transmission mechanism, so it cannot produce the transmission effect of harmonic power, so that there will be poor power reduction effect, large size and heavy weight The lack of heavy and poor transmission stability, resulting in Does not meet the lightweight trend in the bicycle field.
此外,一般諧波齒輪傳動機構主要是由波發生器(即凸輪環)、撓性齒輪(如柔輪)以及剛性齒輪(如剛輪)等三個構件所組成的一種機械動力傳動機構。此機械動力傳動機構是在凸輪環的波發生器作用下,使柔輪產生彈性變形並與剛輪相互作用而達到傳遞運動或動力之目的。在傳動中波發生器迴轉一周,柔輪上某一點循環變形的次數則稱波數。至於柔輪的變形過程則是一個基本對稱的諧波,故稱為諧波傳動。 In addition, the general harmonic gear transmission mechanism is mainly a mechanical power transmission mechanism composed of three components such as a wave generator (that is, a cam ring), a flexible gear (such as a flexible wheel), and a rigid gear (such as a rigid wheel). This mechanical power transmission mechanism is under the action of the wave generator of the cam ring, so that the flexible wheel is elastically deformed and interacts with the rigid wheel to achieve the purpose of transmitting motion or power. In the transmission, the wave generator makes one revolution, and the number of cyclic deformations at a certain point on the flexible wheel is called the wave number. As for the deformation process of the flexible wheel, it is a basically symmetrical harmonic, so it is called a harmonic drive.
再者,習知擺線齒輪減速機皆有體積大、重量重及傳動平穩度不佳的缺失產生。而且現有的電動自行車電動補助力的傳動機構在設計上也有諸多缺失,因而造成體積大,噪音大及傳動輸出比小等諸多缺失。因此,如何開發出一種結合諧波齒輪技術而提升自行車傳動平穩度的自行車動力傳遞技術實已成為相關技術領域業界所亟欲改善與挑戰的技術課題。 In addition, the conventional cycloid gear reducers have the defects of large volume, heavy weight and poor transmission stability. In addition, there are many defects in the design of the existing electric bicycle power transmission mechanism, which results in many defects such as large volume, large noise and small transmission output ratio. Therefore, how to develop a bicycle power transmission technology that combines harmonic gear technology to improve the transmission stability of the bicycle has become a technical issue that the industry in the related technical fields desperately wants to improve and challenge.
因此,鑒於上述習知技術與該專利的缺失,於是本發明人乃經不斷的努力研發之下,終於研發出一套有別於上述習知技術並具功效增進的本發明。 Therefore, in view of the above-mentioned conventional technology and the lack of the patent, the inventor has made continuous efforts to develop a set of inventions that are different from the above-mentioned conventional technology and have improved efficacy.
本發明主要目的在於提供一種電動自行車電動補助力之諧波齒輪傳動機構,主要是將諧波齒輪傳動技術應用於自行車的動力傳動機構上,使柔輪在剛輪固定限制下而實現諧波動力傳動減速的功效,因而具有體積小、重量輕、傳動比數範圍大、傳動精度高、傳動效率高以及傳 動平穩度較佳等特點。達成本發明主要目的之技術手段,係包括殼體、馬達、剛輪、軸承座、輸出盤、柔輪、中空軸及凸輪環。馬達之外環定子固設於殼體容室中段。剛輪之前段管部內周環設卡齒,其後段盤面固設於容室前段。軸承座容置容室前段,外周與軸承座之間介置第一軸承。柔輪之前段盤面受到輸出盤與軸承座夾制定位,柔輪之後段管部伸入前段管部,柔輪之後段管部外周環設有與卡齒嚙合的配卡齒。中空軸中段穿設於馬達之內環轉子。凸輪環內周套設於中空軸前段,凸輪環外周與柔輪之後段管部內周之間介置柔性軸承。 The main purpose of the present invention is to provide a harmonic gear transmission mechanism for electric auxiliary power of an electric bicycle, which mainly applies the harmonic gear transmission technology to the power transmission mechanism of the bicycle, so that the flexible wheel can realize harmonic power under the fixed limitation of the rigid wheel The effect of transmission deceleration, so it has small size, light weight, large transmission ratio range, high transmission precision, high transmission efficiency and transmission Features such as better dynamic stability.
