Description
本發明係有關於一種用於車輛之出力傳動系統;特別是指一種車輛出力軸或出力齒輪組組合彈簧裝置,提高扭力輸出作用之技術。The present invention relates to an output transmission system for vehicles; in particular, it refers to a vehicle output shaft or output gear set combined spring device to improve the torque output effect technology.
應用在車輛或電動車輛方面,例如變速裝置、齒輪組傳遞動力、差速器等,使車輛產生前進、後退等作用之傳動裝置,係已為一習知技藝。例如,台灣第87217364號「汽車傳動裝置」(即,US 6146306號「AUTOMOBILE TRANSMISSION DEVICE」)、專利案,係提供了一個典型的實施例。It is a common art to apply to vehicles or electric vehicles, such as transmission devices, gear sets to transmit power, differentials, etc., to make the vehicle move forward and backward. For example, Taiwan No. 87217364 "Automobile Transmission Device" (ie, US No. 6146306 "AUTOMOBILE TRANSMISSION DEVICE"), a typical embodiment is provided.
習知車輛的變速傳動系統包括了手動、自動、和連續式變速傳動系統等型態;它們使引擎轉軸或馬達轉軸的動力經過一變速控制機構、配裝在一入力軸上的入力齒輪組、和設置在一出力軸上的(傘型齒輪)差速機構、出力齒輪組等裝置,使動力傳遞到該出力軸上,來使車輛獲得不同變速比例的運動。The variable speed transmission system of conventional vehicles includes manual, automatic, and continuous variable speed transmission systems; they make the power of the engine shaft or motor shaft pass through a speed change control mechanism, an input gear set fitted on an input shaft, And the (bevel gear) differential mechanism, output gear set and other devices arranged on an output shaft, so that the power is transmitted to the output shaft, so that the vehicle can obtain different speed ratios.
基本上,該變速控制機構包括複數個分別配裝在入力齒輪組內、外部的類彈簧體和控制推筒;經由手動或自動變速控制電機制動一蝸輪盤轉動,選擇性的驅動不同的滾珠(或推桿)推動該控制推筒,用以使該類彈簧體和該入力齒輪組形成接合或不接合狀態,讓不同齒數的入力齒輪組分別傳動該出力齒輪組和差速機構,使該出力軸產生不同轉速驅動車輛。Basically, the variable speed control mechanism includes a plurality of spring-like bodies and control push cylinders that are respectively installed in the input gear set and outside; through manual or automatic variable speed control motor braking, a worm wheel disc rotates, and selectively drives different balls ( or push rod) to push the control push cylinder to make the spring body and the input gear set form an engaged or non-engaged state, so that the input gear sets with different numbers of teeth drive the output gear set and the differential mechanism respectively, so that the output force The shafts generate different rotational speeds to drive the vehicle.
一個有關車輛變速、傳動裝置在結構設計和操作、應用方面的課題是,習知技藝的出力軸機構和出力齒輪組之間的組合都必須應用多個扣環、軸承(例如,滾珠、滾針、單向、止推軸承…等)等機件,來保持它們轉動自如的輸出動力的穩定度。A problem related to vehicle speed change and transmission in structural design, operation, and application is that the combination of output shaft mechanism and output gear set in the prior art must use multiple snap rings, bearings (for example, balls, needle rollers, etc.) , one-way, thrust bearings, etc.) and other parts to maintain the stability of their freely rotating output power.
例如,在舊法中出力軸機構通常需要配置到至少16個單向軸承的組合,因此形成長期囿於固有傳動機構的型態,使傳統的出力傳動裝置通常存在有結構複雜、組裝麻煩、費時、機構長度/體積較大和成本較高的情形;而這種情形並不是我們所期望的。For example, in the old method, the output shaft mechanism usually needs to be equipped with a combination of at least 16 one-way bearings, so it has been confined to the inherent transmission mechanism for a long time, making the traditional output transmission device usually have complex structure, troublesome assembly, and time-consuming , the situation of larger mechanism length/volume and higher cost; and this situation is not what we expect.
代表性的來說,這些參考資料顯示了在車輛系統方面,有關習知(出力)傳動裝置在結構和應用方面的設計技藝。如果重行設計考量該出力傳動裝置的配合情形,使它的機構設計符合結構組裝精簡的條件,並且使其構造不同於習用者,將可改變它的動力傳輸型態,而有別於舊法,相對改善習知結構複雜、組裝麻煩、費時、機構長度/體積較大和成本較高等情形;或進一步達到提高傳動裝置的扭力輸出的作用;而這些課題在上述的參考資料中均未被教示或具體揭露。Typically, these references show the design skills of conventional (output) transmissions in terms of construction and application in vehicle systems. If the redesign considers the coordination of the output transmission device, making its mechanism design meet the conditions of simplified structural assembly, and making its structure different from that of the conventional one, it will be able to change its power transmission type, which is different from the old method. Relatively improve the known complex structure, cumbersome assembly, time-consuming, large mechanism length/volume and high cost; or further achieve the effect of improving the torque output of the transmission device; and these issues are not taught or specified in the above reference materials expose.
爰是,本發明之主要目的即在於提供一種用於車輛之出力傳動系統,係提供一組裝簡便和動力傳動等作用。所述的出力傳動系統包括出力軸和一彈簧裝置的組合;以及,出力軸配置有出力齒輪組,可轉動自如的輸出動力。彈簧裝置形成有複數個(連續)簧圈的結構,繞設在出力軸上;彈簧裝置定義有第一端、第二端,第一端相接出力軸,第二端組合出力齒輪組的型態,使轉動軸的動力經入力齒輪組傳動出力齒輪組時,配合彈簧裝置蓄積能量,提高車輛(或出力軸)的扭力輸出作用;改善習知結構複雜、組裝麻煩、費時、機構長度/體積較大和成本較高的情形。Therefore, the main purpose of the present invention is to provide a power transmission system for a vehicle, which provides functions such as easy assembly and power transmission. The output transmission system includes a combination of an output shaft and a spring device; and, the output shaft is equipped with an output gear set, which can rotate freely to output power. The spring device forms a structure with a plurality of (continuous) coils, which are wound on the output shaft; the spring device defines a first end and a second end, the first end is connected to the output shaft, and the second end is combined with the output gear set. When the power of the rotating shaft is transmitted through the input gear set to the output gear set, the spring device is used to accumulate energy to improve the torque output of the vehicle (or output shaft); to improve the conventional complex structure, troublesome assembly, time-consuming, mechanism length/volume Larger and more costly situations.
根據本發明之用於車輛之出力傳動系統,該彈簧裝置的簧圈結構配置型態,是從第一端朝第二端方向,使相鄰接的簧圈結構的重疊區域形成遞減的型態;並且,每一相鄰簧圈結構至少有局部區域相連接。因此,當出力齒輪組帶動彈簧裝置、出力軸轉動時,使彈簧裝置從第二端朝第一端方向逐漸(迫緊)在出力軸上蓄積能量,相對使出力軸增加扭力輸出作用。According to the output transmission system for vehicles of the present invention, the configuration of the coil structure of the spring device is from the first end toward the second end, so that the overlapping area of the adjacent coil structures forms a decreasing pattern. and, each adjacent coil structure is connected at least in a partial area. Therefore, when the output gear set drives the spring device and the output shaft to rotate, the spring device gradually (tightens) accumulates energy on the output shaft from the second end toward the first end, thereby increasing the torque output effect of the output shaft.
請參閱第1、2及3圖,本發明用於車輛之出力傳動系統,包括一連接動力源的轉動軸80(或稱入力軸)和出力軸90的組合;動力源(圖未顯示)可選擇一馬達、內燃機或引擎的型態,使轉動軸80產生逆時針或順時針方向之轉動動力。Please refer to Fig. 1, 2 and 3, the output transmission system of the present invention is used for the vehicle, comprises the combination of a rotating shaft 80 (or called input shaft) and
圖中顯示了轉動軸80設置有一入力齒輪組10和變速控制部20。這入力齒輪組10選擇一個三檔(或四檔)傳動系統;因此,入力齒輪組10至少包括第一~第三入力齒輪11~13。入力齒輪組10和變速控制部20屬習知技藝,故未予詳述。The figure shows that the rotating shaft 80 is provided with an
相對於入力齒輪組10,出力軸90上裝置有一出力齒輪組60、彈簧裝置50(及/或差速機構70),而共同構成出力傳動系統,用以輸出動力。當轉動軸80的轉動動力經入力齒輪組10傳動該出力齒輪組60轉動時,出力齒輪組60會傳動該出力軸90(及差速機構70)轉動,使出力軸90產生不同轉速的驅動車輪W轉動。Relative to the
第1、2及3圖也描繪了出力齒輪組60也是選擇一個三檔(或四檔)傳動系統,具有複數個直徑不同的出力齒輪,包括可轉動自如的第一~第三出力齒輪61~63,分別和該第一~第三入力齒輪11~13嚙合。第一、二出力齒輪61、62(及/或第二、三出力齒輪62、63)之間,配置有一單向軸承45;使每一出力齒輪61~63依序只能容許低階齒輪傳動高一階齒輪,但高一階齒輪不能傳動低一階齒輪。Figures 1, 2 and 3 also depict that the output gear set 60 also selects a third-speed (or fourth-speed) transmission system, which has a plurality of output gears with different diameters, including the rotatable first to
在可行的實施例中,出力齒輪組60的第一出力齒輪61配合軸承40(例如,滾針軸承或其類似軸承),裝設組合出力軸90。出力軸90設置有一翼部95,配合固定器99樞接第三出力齒輪63。以及,第二出力齒輪62和翼部95之間配置有一單向軸承45,使第二出力齒輪62可傳動第三出力齒輪63,但第三出力齒輪63不能傳動第二出力齒輪62。In a feasible embodiment, the
圖中顯示了第二出力齒輪62和出力軸90之間的區域,配裝有一彈簧裝置50。彈簧裝置50可選擇一類似板簧的結構,形成有複數個(連續)簧圈結構55,繞設在出力軸90上的型態。The figure shows the area between the
在所採的實施例中,彈簧裝置50定義有第一端51、第二端52,第一端51配合軸承40(或單向軸承)和固定件59,相接(或組合)出力軸90;固定件59可選擇鍵、銷或其類似物。以及,第二端52配合固定件59,組合(或固定於)出力齒輪組60(或第二出力齒輪62)的型態,使轉動軸80的動力經入力齒輪組10傳動出力齒輪組60時,配合彈簧裝置50蓄積能量,提高車輛(或出力軸)的扭力輸出作用。In the adopted embodiment, the
具體來說,彈簧裝置50的簧圈結構55的配置型態,是從第一端51朝第二端52方向,使相鄰接的簧圈結構55的重疊區域形成遞減的型態,並且每一相鄰簧圈結構55至少有局部區域相連接,使第二端52的簧圈結構55蓄積的能量朝第一端51方向的簧圈結構55蓄積的能量形成遞增的型態。因此,當彈簧裝置50響應出力齒輪組60轉動而轉動時,越接近第一端51的簧圈結構55蓄積的能量(或作用力)越大,越接近第二端52的簧圈結構55蓄積的能量(或作用力)越小。Specifically, the arrangement pattern of the
也就是說,當出力齒輪組60帶動彈簧裝置50、出力軸90轉動時,彈簧裝置50從第二端52朝第一端51方向逐漸(迫緊)在出力軸90上蓄積能量,相對使出力軸90(逐漸)增加扭力輸出作用。That is to say, when the output gear set 60 drives the
例如,假設轉動軸80帶動第一入力齒輪11傳動第一出力齒輪61轉動時,定義為第一檔(或第一速);以及,配合單向軸承45,使第二出力齒輪62也同步隨第一出力齒輪61的轉動。並且,第二出力齒輪62的轉動會帶動彈簧裝置50轉動,從第二端52朝第一端51的方向逐漸迫緊在出力軸90上蓄積能量,而帶動出力軸90轉動。For example, when the rotating shaft 80 drives the
假設轉動軸80帶動第二入力齒輪12傳動第二出力齒輪62轉動時,定義為第二檔(或第二速);配合單向軸承45,使第二出力齒輪62直接帶動彈簧裝置50轉動,從第二端52朝第一端51的方向逐漸迫緊在出力軸90上蓄積能量,而帶動出力軸90轉動。Assuming that the rotating shaft 80 drives the
可了解的是,假設轉動軸80帶動第三入力齒輪13傳動第三出力齒輪63轉動時,定義為第三檔(或第三速);第三檔(或第三速)屬於高速檔,使第三入力齒輪13直接傳動第三出力齒輪63和出力軸90轉動,而不會使彈簧裝置50蓄積能量。It can be understood that, assuming that the rotating shaft 80 drives the
代表性的來說,這用於車輛之出力傳動系統相較於舊法而言,係包括了下列的優點和考量:
1. 該出力傳動系統的出力齒輪組60、彈簧裝置50和出力軸90的組合結構,已被重行設計考量。例如,出力齒輪組60和出力軸90之間,設置彈簧裝置50;彈簧裝置50成複數個簧圈結構50,彈簧裝置50從第一端51朝第二端52方向,使相鄰接的簧圈結構55的重疊區域形成遞減的型態等部分,明顯不同於習知技藝的結構型態,相對改善了習知結構複雜、組裝麻煩、費時、機構長度/體積較大和成本較高等情形。
2. 特別是,使彈簧裝置50的第一端51固定在出力軸90,第二端52固定出力齒輪組60的結構型態,使它的機構設計達到提高傳動系統的扭力輸出的作用,改善了舊法單只有動力輸出的功能。
Typically, this applies to the output drive system of a vehicle and includes the following advantages and considerations compared to the old method:
1. The combined structure of the
故,本發明係提供了一有效的用於車輛之出力傳動系統,其空間型態係不同於習知者,且具有舊法中無法比擬之優點,係展現了相當大的進步,誠已充份符合發明專利之要件。Therefore, the present invention provides an effective power transmission system for vehicles. Its spatial configuration is different from the known ones, and it has incomparable advantages in the old methods. It shows considerable progress and is fully satisfied.
