Description
本發明係有關於一種防滑差速器，尤指一種能增加每一行星齒輪接觸面積以提高摩擦力與防滑效果的防滑差速器。 The invention relates to a non-slip differential, in particular to a non-slip differential which can increase the contact area of each planetary gear to improve the friction and anti-slip effect.
一般車輛進行轉彎時，為了應付兩側輪胎因迴轉半徑的不同，會在兩側輪胎之間安裝配置有一差速器。該差速器通常為簡單的機械構造，其主要係藉由二側輪軸將二行星斜齒輪與一側齒輪嚙接，以利於轉彎時承受該側齒輪不同轉速的帶動。 In general, when a vehicle makes a turn, in order to cope with the difference in the radius of gyration of the tires on both sides, a differential is installed between the tires on both sides. The differential is usually a simple mechanical structure, which mainly engages the two planetary helical gears with one side gear by the two side axles, so as to facilitate the rotation of the side gears at different rotational speeds during cornering.
由於兩側輪胎同時於直線行進時，該差速器只能被動配合而無法主動限制輪軸的轉動，若因此陷入泥濘或濕滑的地面之中，其中一側輪胎將懸空而造成打滑，進一步導致另一側輪胎也同時失去動力。 Since the tires on both sides travel in a straight line at the same time, the differential can only passively cooperate and cannot actively limit the rotation of the axle. If it is caught in a muddy or slippery ground, one of the tires will be suspended and cause slippage, further causing The other side of the tire also lost power.
為了避免上述輪軸空轉或失去動力等情形產生，後來便有人提出一種防滑差速器，而現有防滑差速器的種類諸如有機械式的離合器、利用螺旋式行星齒輪的組合、或者多板離合器式等。其中螺旋齒輪差速器是利用齒輪與齒輪之間的磨擦力來限制動力一直傳輸至空轉輪，總合的摩擦力越大，防滑的效果越好。 In order to avoid the above-mentioned axle idling or loss of power, etc., a slip-resistant differential has been proposed, and the types of existing slip-resistant differentials are mechanical clutches, combinations using helical planetary gears, or multi-plate clutches. Wait. The helical gear differential utilizes the frictional force between the gear and the gear to limit the transmission of power to the idler. The greater the friction of the total, the better the anti-skid effect.
然而現有齒輪防滑差速器內部的行星齒輪，只有一對一的嚙合，每一行星齒輪之間互相嚙合的面積是有限的，導致齒輪之間的摩擦力少而有防滑效果不佳的缺失。且因為內部行星齒輪是以一對一嚙合設置，必須 在兩輪差速範圍較大時才能使該齒輪防滑差速器發揮功效，故因為現有齒輪防滑差速器有這些缺點而有再加以改良之必要。 However, the planetary gears inside the existing gear anti-skid differential have only one-to-one meshing, and the area of mutual engagement between each of the planetary gears is limited, resulting in less friction between the gears and a lack of anti-slip effect. And because the internal planetary gears are arranged in one-to-one engagement, it must The gear anti-skid differential can be made effective when the differential range of the two wheels is large, so that the existing gear anti-skid differential has these shortcomings and needs to be improved.
本發明的目的在於提出一種增加每一行星齒輪之間嚙合的接觸面積而能提高摩擦力與防滑效果的防滑差速器。 SUMMARY OF THE INVENTION An object of the present invention is to provide an anti-skid differential that can increase the frictional and anti-slip effects by increasing the contact area between each of the planetary gears.

請復閱第1圖至第5圖所示，當汽車其中一輪胎打滑或深入泥濘時，其所有的動力都在打滑輪上，為了避免失去動力，會透過該防滑差速器1作動使打滑的輪胎傳輸動力至另一相對未打滑的輪胎上，即是讓該第一傳動軸轉動速度比該第二傳動軸轉動速度快。更具體說明，藉由該第一傳動輪的轉動帶動該第一傳動齒輪61與該些第一行星齒輪62轉動，此後該些第 一行星齒輪62再帶動該些第二行星齒輪64與該第二傳動齒輪63轉動，最後透過該第二傳動軸的轉動來脫離打滑或防止陷入泥濘之中。 Please review Figures 1 to 5. When one of the tires of the car slips or goes deep into the mud, all the power is on the pulley. In order to avoid losing power, the slip differential 1 will be used to make the slip.
