Description
本發明係關於一種變速器，尤其是關於一種利用於變速系統而能組合控制變速段位之變速器調整機構。 BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a transmission, and more particularly to a transmission adjustment mechanism that can be used in combination with a shifting system to control a shifting range.
變速器係普遍利用於交通工具之傳動系統中，用以切換齒輪傳動系統之傳動比，藉此以達到增減速或增減扭矩之目的。 特別是關於自行車之變速系統，由於自行車運動在現今社會已成為一種最為風行之休閒活動之一，為了增加騎乘時之舒適性，使騎乘者在不同之地形變化間，仍能夠悠閒且不費力地騎乘，此些自行車通常設有一多段位之變速系統，使能於上坡路段時減輕腳踏之力道，達到輕鬆騎乘之目的。 The transmission system is commonly used in the transmission system of a vehicle to switch the gear ratio of the gear transmission system, thereby achieving the purpose of increasing or decreasing the torque or increasing or decreasing the torque. Especially with regard to the bicycle shifting system, bicycle racing has become one of the most popular leisure activities in today's society. In order to increase the comfort during riding, the rider can still be leisurely and not in different terrain changes. Struggling to ride, these bicycles usually have a multi-segment shifting system that can reduce the pedaling force on the uphill section for easy riding.
目前自行車之變速系統，多屬設置於後輪之外變速器，其係利用飛輪直徑之傳動比差異，將鏈條撥移切換至所欲嚙合之飛輪段位，達到變速之目的。此種變速系統，主要是經由一變速纜線拉伸所連接之變速控制器，使其以所預設之位移方式將鏈條撥移至預定之飛輪上。除此之外，為了增加美觀，減輕多段系統其飛輪的體積與重量，並進一步增加變速之段位，中高階之自行車有逐漸以內變速器取代外變速器之趨勢。習知內變速器係設於後輪花轂中，其包括有數組之齒輪傳動機構，常見者係利用行星齒輪系統，藉由複數個行星齒輪系統所產生之傳動比組合，變化出數種之變速段位。 At present, the bicycle shifting system is mostly disposed outside the rear wheel transmission, which utilizes the difference of the transmission ratio of the flywheel diameter to switch the chain shift to the desired flywheel segment position to achieve the purpose of shifting. The shifting system mainly stretches the connected shifting controller via a shifting cable to move the chain to the predetermined flywheel in a predetermined displacement manner. In addition, in order to increase the appearance, reduce the volume and weight of the flywheel of the multi-stage system, and further increase the shift position, the middle and high-end bicycles gradually have the tendency to replace the external transmission with the internal transmission. The conventional internal transmission is disposed in the rear wheel hub, and includes an array of gear transmission mechanisms. The common ones use a planetary gear system to change a plurality of shifting speeds by a combination of gear ratios generated by a plurality of planetary gear systems. Segment position.
前述習知之內變速器，為達到各行星齒輪系統間之組合轉動，必須藉由一變速調整軸，依其所設定之段位，卡掣其中之一或數個行星齒輪系統的作動，進而達成切換檔位之效果。該 習知變速調整軸上於預定位置設有可選擇性作動之卡掣塊，藉由該變速調整軸之左右橫移，或選擇性的使卡掣塊凸出，使該些卡掣塊能夠卡掣到所欲控制之行星齒輪系統中之齒輪。此種卡掣方式因位移方式有限，且行星齒輪系統之設置複雜，因而所能組合出之變速段位有限。此外，由於該卡掣塊係徑向單邊之制動，常於經久使用後使被制動之齒輪產生偏軸磨損之現象，進而影響相對齒輪間之嚙合密合狀態，使齒輪之使用耐久性不佳。 In the above-mentioned internal transmission, in order to achieve the combined rotation between the planetary gear systems, it is necessary to achieve the switching gear by one of the shifting adjustment shafts, according to the set position, by one or several planetary gear systems. Bit effect. The The conventional shifting adjustment shaft is provided with a selectively actuatable clamping block at a predetermined position, and the locking lever adjusts the left and right traverse, or selectively causes the latching block to protrude, so that the latching blocks can be stuck Pick up the gear in the planetary gear system you want to control. Because of the limited displacement mode and the complicated arrangement of the planetary gear system, the type of the clamping method has a limited number of shifting sections. In addition, since the latching block is braked on one side in the radial direction, the braked gear is often subjected to off-axis wear after being used for a long time, thereby affecting the meshing close state between the gears, so that the durability of the gear is not used. good.

The position and shape of the outer displacement shaft pin 81 and the inner displacement shaft pin 82 are not limited in any way. However, since the outer displacement shaft pin 81 needs to be slipped in the guide groove 61, the shape should be smooth, so it can be cylindrical, and the cylinder is slipped, or the sphere or the arc body. Shape, in order to slip, but not limited to this shape.
變速器調整機構100中旋轉控制件30所設之撥槽31，係用於與內位移軸銷32相卡掣或固定，使於內位移軸銷32位移轉動時，帶動變速器調整機構100之轉動。 The dial 31 provided in the rotation control member 30 of the transmission adjusting mechanism 100 is used for locking or fixing with the inner displacement shaft pin 32 to drive the rotation of the transmission adjusting mechanism 100 when the inner displacement shaft pin 32 is displaced.
