Description

【０００１】
【発明の属する技術分野】
本発明は、５速手動変速装置(マニュアルトランスミッション)を６速手動変速装置へ変更する改造方法に関する。
【０００２】
【従来の技術】
自動車における変速装置は、動力伝達の入切のほか、変速比を変更できるようにするため、複雑な構造をしている(例えば特開平09-096344号参照)。手動変速装置で言えば、前進５段又は６段、後進１段からなるギア部をミッションケース内に納め、前記ミッションケースに付設した操作部を操作して、各段の駆動ギア又は被動ギアを切り替えて変速する。これらギア部及び操作部がエンジンからの入力軸と駆動輪への出力軸との間に設けられる結果、一般の手動変速装置は構造が複雑になり、段数を増設することを含む改造が難しい。このため、通常は予め望む段数又はギア比を備えた自動車を選択し、購入していた。
【０００３】
【発明が解決しようとする課題】
自動車の選択、購入に際しては、外観、装備及びエンジン等が選択基準とされるため、これら外観、装備及びエンジン等には選択オプションが多い。しかし、変速装置は相対的に選択幅が狭く、またより多くの希望を満足するように平均的な構成を採用することが多いので、自動車購入後に改造を望む人が少なくない。根本的に、変速装置自体を交換する改造も考えられるが、通常は部分的な部品交換によって実現する例がほとんどである。
【０００４】
こうした部品交換による変速装置の改造では、段数を増設する場合の(a)追加段数の配置と、(b)追加した段数に伴う他のギアの配置転換及び操作部の変更が重要となる。改造は、あくまで既存のギアや操作部を変更せずに、段数を増設するので、前記(a),(b)を実現する手段が重要となる。そこで、できるだけ容易に前記(a),(b)を実現する改造方法を確立すべく、検討した。
【０００５】
【課題を解決するための手段】
検討の結果、１-２速、３-４速、５速-Ｒ(後退)からなるシフトパターンを有する５速手動変速装置に１段増設し、Ｒ(後退)、１-２速、３-４速、５速-６速からなるシフトパターンを有する６速手動変速装置へ変更する改造方法であって、まずミッションケース内において、５速駆動ギアを設けてある入力軸端を延長してこの入力軸端に増設する６速駆動ギアを装着し、次に出力軸に接続するデファレンシャルケースの外面に６速被動ギアを取り付け、５速駆動ギア及び後退駆動ギアの切替に用いていたスリーブハブにより５速駆動ギア及び６速駆動ギアを切り替えるようにし、ミッションケース外において、シフトレバーのシフト位置に従って自転するセレクタアームに取付角度の異なる前進選択シフタフォーク及び後退選択シフタフォークを取り付け、シフトレバーをＲ(後退)にシフトさせた時に前記後退選択シフタフォークが接続する後退係合シフタフォークを設け、この後退係合シフタフォークから後退駆動ギアを操作する後退駆動シフタフォークに繋がるシフタロッドを延設する５速手動変速装置を６速手動変速装置へ変更する改造方法を開発した。
【０００６】
改造の基礎となる５速手動変速装置構成は様々あり、またシフトパターンも分かれるため、本発明の適用は、(1)１-２速、３-４速、５速-Ｒ(後退)からなるシフトパターン＝乗用車用変速機のシフトパターンフロアシフト式５段Ａ型シフトパターンを有する５速手動変速装置を、(2)Ｒ(後退)、１-２速、３-４速、５速-６速からなるシフトパターン＝大型自動車用変速機のシフトパターン６段Ａ型シフトパターンを有する６速手動変速装置へ変更する改造に限られる。
【０００７】
本発明の改造は、改造の基礎となる５速手動変速装置が有する４速駆動ギアと後退駆動ギア用との切替に用いていたスリーブハブを利用して６速駆動ギアを操作することとし、この６速駆動ギアを延長した入力軸端に装着する。そして、対応する６速被動ギアは、出力軸に取り付ける余裕がないために、出力軸端には位置するデファレンシャルケース(センターデファレンシャルケース)外面に取り付ける。このとき、ギア比の関係から、適宜５速以下の各駆動ギア又は被動ギアを交換してもよい。単に６速駆動ギア及び被動ギアを追加する場合はオーバードライブの追加となり、６速駆動ギア及び被動ギアの追加に加えて５速以下の各駆動ギア又は被動ギアを交換する場合は、ギア比の見直しによる加速感の連続性や燃費を改善する。
【０００８】
６速駆動ギアの操作は、改造の基礎となる５速手動変速装置における５速駆動ギアと後退駆動ギアの切替を図っていたスリーブハブを利用するのが最も簡便である。しかし、これによって後退駆動ギアの操作部がなくなるため、本発明ではシフトパターンを１-２速、３-４速、５速-Ｒ(後退)からなる乗用車用のシフトパターンから、Ｒ(後退)、１-２速、３-４速、５速-６速からなる大型自動車用のシフトパターンへと変更し、後退駆動ギアの操作部を別途ミッションケース外に設けることとした。具体的には、シフトレバーで自転するセレクタアームに別途後退選択シフタフォークを追加し、このシフターフォークを用いて後退係合シフタフォーク及びシフタロッドを介して後退駆動シフタフォークを操作する。
【０００９】
【発明の実施の形態】
以下、本発明の実施形態について、図を参照しながら説明する。図１は本発明を適用した改造後の６速手動変速装置の左側面断面図、図２はシフトレバーから延びるジョイントロッド１と改造後の操作部との連結を表した部分左側面図、図３は前進選択シフタフォーク２の切替関係を表した部分拡大図、図４は後退選択シフタフォーク３の切替関係を表した部分拡大図、図５はシフトレバーから延びるジョイントロッド１とセレクタアーム４との連結部位のニュートラル時における断面図、図６は同連結部位の後退時における断面図、図７は後退駆動ギア５の操作部のみを抜粋して表した６速手動変速装置の左側面図であり、図８は後退駆動ギア５切替用の後退駆動シフタフォーク６とシフタロッド７,８との連結関係を表した断面図である。
【００１０】
本発明に基づく改造は、図１に見られるように、基本的には既存部品の流用を図り、増速する６速駆動ギア９及び６速被動ギア10を追加する態様で適用する。この場合、６速はいわゆるオーバードライブとして扱われる。しかし、実際には滑らかな加速を図るため、適宜各速駆動ギア又は被動ギアを交換して、ギア比を調節することが望ましい。この場合、端部を延長するために交換する入力軸11に対して、３速駆動ギア12、４速駆動ギア13及び５速駆動ギア14を交換した後に６速駆動ギア９を追加する。出力軸15に設けてある３速被動ギア16、４速被動ギア17及び５速被動ギア18は交換しない。６速駆動ギア９逸脱防止のため、入力軸11端には止着カラー19を取り付けるとよい。また、出力軸15に対しては、１速被動ギア22及び２速被動ギア23を交換する。入力軸11に設けてある１速駆動ギア20及び２速駆動ギア21は交換しない。それぞれのスリーブハブ24,25.26及びシンクロナイザ27,28は既存のものを流用できるが、６速駆動ギア用シンクロナイザ29は追加する。また、６速被動ギア10はデファレンシャルケース30の外面に固着する。
【００１１】
本発明では、図２に見られるように、Ｒ(後退)、１-２速、３-４速、５速-６速からなる大型自動車用のシフトパターン31を用いる。本例では、図２に向かって手前にＲ(後退)があり、奥に５-６速があり、シフトレバーの左右(図２中手前から奥)の動きが、ジョイントロッド１の奥から手前への揺動となる。このジョイントロッド１の揺動はセレクタアーム４を自転回動させ、１-６速の範囲では前進選択シフタフォーク２がいずれかの前進係合シフタフォーク32,33,34に係合して変速する(図３)。そして、シフトレバーをＲに入れた時に、初めて後退選択シフタフォーク３が後退係合シフタフォーク35に係合し、後退駆動ギア５(図１参照)が操作できるようになる(図４)。シフトレバーは、ニュートラル位置で、ジョイントロッド１とセレクタアーム４との連結部位におけるチェックボール36及びチェック嵌合孔37が嵌合して安定状態とし(図５)、変速操作に際しては前記嵌合を軽い抵抗感として節度感を与えている(図６)。
【００１２】
既存の後退駆動ギア５の操作部を６速への変速用に用いたため、図７に見られるように、新たにＲへの変速用の操作部をミッションケース38外面に設けている。具体的には、シフトレバーをＲへ入れるためにシフトパターン左端へ移動させると、セレクタアーム４の一端に設けた後退選択シフタフォーク３が後退係合シフタフォーク35に係合し、次いでＲに向けてシフトレバーを前進操作(後退操作も可)すると、この後退係合シフタフォーク35の動きがシフタロッド７,８を伝達して後退駆動シフタフォーク６を動かし、シフタコンプリート42の揺動により後退駆動ギア５を操作する(図８)。本発明は改造方法であり、例えばシフトレバーや後退駆動ギア５は既存のものを用いるため、必ずしも後退選択シフタフォーク３と後退駆動シフタフォーク６とが直線上に並ばない。このため、本例ではシフタロッド７,８を分割して連結ロッド40で連結し、シフタロッド８をミッションケース38外面に取り付けた支持ステー39で支持している。また、シフタロッド８を復帰方向にコイルバネ41で付勢している。
【００１３】
【発明の効果】
本発明は、すべての車種に適用できるものではないが、適用できる車種については比較的容易に変速段数を増やすことができる。これは、課題である(a)追加段数の配置と、(b)追加した段数に伴う他のギアの配置転換及び操作部の変更とを解決する効果である。また、既存部品の流用も多いので、改造コストも低廉に抑えることができる。こうして、本発明は５速手動変速装置を６速手動変速装置へ変更する実用的な改造方法を提供することができるようになる。

BACKGROUND OF THE INVENTION
The present invention relates to a modification method for changing a 5-speed manual transmission to a 6-speed manual transmission.
[0002]
[Prior art]
BACKGROUND ART A transmission in an automobile has a complicated structure so that the transmission ratio can be changed in addition to on / off of power transmission (see, for example, Japanese Patent Laid-Open No. 09-096344). In the case of a manual transmission, a gear portion consisting of 5 or 6 forward speeds and 1 reverse speed gear is housed in a mission case, and an operation portion attached to the transmission case is operated to drive or drive gears at each stage. Change and shift. As a result of the gear unit and the operation unit being provided between the input shaft from the engine and the output shaft to the drive wheel, a general manual transmission has a complicated structure and is difficult to be modified including an increase in the number of stages. For this reason, an automobile having a desired number of stages or gear ratio is usually selected and purchased in advance.
[0003]
[Problems to be solved by the invention]
When selecting and purchasing a car, the appearance, equipment, engine, and the like are used as selection criteria. Therefore, there are many selection options for the appearance, equipment, engine, and the like. However, since the transmission has a relatively narrow selection range and often adopts an average configuration so as to satisfy more hopes, there are many people who desire remodeling after purchasing an automobile. Fundamentally, modifications that replace the transmission itself are conceivable, but most of the examples are usually realized by partial replacement of parts.
[0004]
In such a modification of the transmission by exchanging parts, it is important to (a) arrange the additional number of stages when adding the number of stages, and (b) change the arrangement of other gears and change the operation unit according to the added number of stages. In the modification, the number of stages is increased without changing the existing gear and operation unit, and means for realizing the above (a) and (b) is important. Therefore, studies were made to establish a remodeling method for realizing the above (a) and (b) as easily as possible.
[0005]
[Means for Solving the Problems]
As a result of the study, one stage was added to the 5-speed manual transmission with a shift pattern consisting of 1-2 speed, 3-4 speed, 5 speed-R (reverse), R (reverse), 1-2 speed, 3- This is a modification method for changing to a 6-speed manual transmission having a shift pattern of 4th speed, 5th speed-6th speed, and first, the input shaft end provided with the 5th speed drive gear is extended in the transmission case. Install an additional 6-speed drive gear at the input shaft end, then attach a 6-speed driven gear to the outer surface of the differential case connected to the output shaft, and use the sleeve hub used to switch between the 5-speed drive gear and the reverse drive gear. A forward-selection shifter fork and a reverse-selection shifter fork with different mounting angles are attached to the selector arm that rotates according to the shift position of the shift lever outside the transmission case. A shifter shifter fork that is connected to the reverse selection shifter fork when the shift lever is shifted to R (reverse) is installed, and a shifter rod connected to the reverse drive shifter fork that operates the reverse drive gear from the reverse engagement shifter fork A remodeling method has been developed to change the 5-speed manual transmission, which is extended to the 6-speed manual transmission.
[0006]
Since there are various 5-speed manual transmission configurations that are the basis for remodeling and the shift patterns are also different, the application of the present invention consists of (1) 1-2 speed, 3-4 speed, 5 speed-R (reverse) Shift pattern = shift pattern for passenger car transmission 5 speed manual transmission with floor shift type 5-speed A-type shift pattern: (2) R (reverse), 1-2 speed, 3-4 speed, 5 speed-6 Shift pattern consisting of high speed = shift pattern for large automobile transmissions Limited to remodeling to change to a 6-speed manual transmission having a 6-stage A-type shift pattern
[0007]
In the modification of the present invention, the 6-speed drive gear is operated by using the sleeve hub used for switching between the 4-speed drive gear and the reverse drive gear of the 5-speed manual transmission which is the basis of the modification, This 6-speed drive gear is attached to the extended input shaft end. The corresponding 6-speed driven gear is attached to the outer surface of a differential case (center differential case) located at the end of the output shaft because there is no room for attachment to the output shaft. At this time, from the relationship of the gear ratio, each driving gear or driven gear of the fifth speed or less may be appropriately replaced. When adding 6-speed drive gear and driven gear simply, overdrive is added. In addition to adding 6-speed drive gear and driven gear, when replacing each drive gear or driven gear under 5th speed, the gear ratio Improve continuity of acceleration and fuel efficiency by review.
[0008]
For the operation of the 6-speed drive gear, it is most convenient to use a sleeve hub that is designed to switch between the 5-speed drive gear and the reverse drive gear in the 5-speed manual transmission that is the basis of the modification. However, this eliminates the operation part of the reverse drive gear, so in the present invention, the shift pattern is changed from a shift pattern for a passenger car consisting of 1-2 speed, 3-4 speed, 5 speed-R (reverse) to R (reverse). The shift pattern was changed to a shift pattern for large vehicles consisting of 1-2, 3-4, and 5-6 speeds, and the operation unit for the reverse drive gear was separately provided outside the transmission case. Specifically, a reverse selection shifter fork is separately added to the selector arm that is rotated by the shift lever, and the reverse drive shifter fork is operated via the reverse engagement shifter fork and the shifter rod using this shifter fork.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a left side sectional view of a modified six-speed manual transmission to which the present invention is applied, and FIG. 2 is a partial left side view showing the connection between the joint rod 1 extending from the shift lever and the modified operating portion. 3 is a partially enlarged view showing the switching relationship of the forward selection shifter fork 2, FIG. 4 is a partially enlarged view showing the switching relationship of the backward selection shifter fork 3, and FIG. 5 is a diagram showing the joint rod 1 and selector arm 4 extending from the shift lever. FIG. 6 is a cross-sectional view when the connecting portion is retracted, and FIG. 7 is a left side view of the six-speed manual transmission that shows only the operating portion of the reverse drive gear 5. FIG. 8 is a cross-sectional view showing the connection relationship between the reverse drive shifter fork 6 for switching the reverse drive gear 5 and the shifter rods 7 and 8.
[0010]
As shown in FIG. 1, the modification based on the present invention is basically applied in such a manner that existing parts are diverted and a 6-speed drive gear 9 and a 6-speed driven gear 10 are added. In this case, the sixth speed is treated as a so-called overdrive. However, in practice, in order to achieve smooth acceleration, it is desirable to adjust the gear ratio by appropriately replacing each speed drive gear or driven gear. In this case, the 6th speed drive gear 9 is added after the 3rd speed drive gear 12, the 4th speed drive gear 13 and the 5th speed drive gear 14 are replaced with respect to the input shaft 11 to be replaced to extend the end. The third speed driven gear 16, the fourth speed driven gear 17, and the fifth speed driven gear 18 provided on the output shaft 15 are not replaced. In order to prevent the sixth speed drive gear 9 from departing, a fastening collar 19 may be attached to the end of the input shaft 11. For the output shaft 15, the first speed driven gear 22 and the second speed driven gear 23 are exchanged. The first speed drive gear 20 and the second speed drive gear 21 provided on the input shaft 11 are not replaced. Existing sleeve hubs 24, 25.26 and synchronizers 27, 28 can be used, but a 6-speed drive gear synchronizer 29 is added. The sixth speed driven gear 10 is fixed to the outer surface of the differential case 30.
[0011]
In the present invention, as shown in FIG. 2, a shift pattern 31 for a large-sized automobile composed of R (reverse), 1-2 speed, 3-4 speed, 5 speed-6 speed is used. In this example, there is R (reverse) toward the front in FIG. 2, 5-6 speed in the back, and the movement of the shift lever from left to right (from front to back in FIG. 2) It will be rocking. This swinging of the joint rod 1 causes the selector arm 4 to rotate and rotate, and the forward selection shifter fork 2 engages with any of the forward engagement shifter forks 32, 33, 34 in the range of 1-6 speed. (Figure 3). When the shift lever is put into R, the reverse selection shifter fork 3 is engaged with the reverse engagement shifter fork 35 for the first time, and the reverse drive gear 5 (see FIG. 1) can be operated (FIG. 4). At the neutral position, the shift lever is brought into a stable state by fitting the check ball 36 and the check fitting hole 37 at the connecting portion of the joint rod 1 and the selector arm 4 (FIG. 5). It gives a sense of moderation as a light resistance (Fig. 6).
[0012]
Since the operating portion of the existing reverse drive gear 5 is used for shifting to the 6th speed, an operating portion for shifting to R is newly provided on the outer surface of the mission case 38 as seen in FIG. Specifically, when the shift lever is moved to the left end of the shift pattern in order to enter R, the reverse selection shifter fork 3 provided at one end of the selector arm 4 is engaged with the reverse engagement shifter fork 35 and then toward R. When the shift lever is operated forward (reverse operation is also possible), the movement of the reverse engagement shifter fork 35 transmits the shifter rods 7 and 8 to move the reverse drive shifter fork 6, and the shifter complete 42 swings to move the reverse drive gear. 5 is operated (FIG. 8). The present invention is a remodeling method. For example, since the existing shift lever and reverse drive gear 5 are used, the reverse selection shifter fork 3 and the reverse drive shifter fork 6 are not necessarily arranged in a straight line. Therefore, in this example, the shifter rods 7 and 8 are divided and connected by the connecting rod 40, and the shifter rod 8 is supported by the support stay 39 attached to the outer surface of the transmission case 38. Further, the shifter rod 8 is urged by a coil spring 41 in the return direction.
[0013]
【The invention's effect】
The present invention is not applicable to all vehicle types, but the number of shift stages can be increased relatively easily for applicable vehicle types. This is an effect of solving the problems (a) the arrangement of the additional stage number, and (b) the change of the arrangement of other gears and the change of the operation unit according to the added stage number. In addition, since the existing parts are often diverted, the modification cost can be kept low. Thus, the present invention can provide a practical modification method for changing a 5-speed manual transmission to a 6-speed manual transmission.
