Description

本発明は、自動車における自動変速機のシフトレバーの切換操作で、パーキング、リバース、ニュートラル、ドライブ、２速、１速というようなシフトポジションを示すポジション信号を発生する自動変速機用コントロールスイッチに関するものである。   The present invention relates to a control switch for an automatic transmission that generates a position signal indicating a shift position such as parking, reverse, neutral, drive, 2nd speed, and 1st speed by switching operation of a shift lever of an automatic transmission in an automobile. It is.

従来より自動変速機（オートマティック・トランスミッション）を備えた自動車では、シフトレバーの切換操作でパーキング、リバース、ニュートラル、ドライブ、２速、１速というような自動変速機のシフトポジションを示すポジション信号を発生する自動変速機用コントロールスイッチが用いられ、それぞれのポジション信号に応じて制御系のマイクロコンピュータに操作指令を与えるようになっている。   Conventionally, vehicles equipped with automatic transmissions (automatic transmissions) generate position signals indicating the automatic transmission shift position, such as parking, reverse, neutral, drive, 2nd speed, and 1st speed, by shifting the shift lever. A control switch for automatic transmission is used, and an operation command is given to the microcomputer of the control system in accordance with each position signal.

この種の自動変速機用コントロールスイッチの一例として、図４並びに図５に示すようにアルミダイカスト製のケース３１ａと合成樹脂製のカバー３１ｂとから成るハウジング３１と、このハウジング３１の内部に回動自在に収められる可動体４０とを備え、ハウジング３１が自動変速機に取り付けられるとともに、シフトレバーの操作に応じて回動するシフト切り換え用のマニュアルシャフト６０に可動体４０が固定されるものがある（例えば、特許文献１参照）。つまり、可動体４０はシフトレバーの回動に応じてマニュアルシャフト６０と一体的に回動するのである。   As an example of this type of automatic transmission control switch, as shown in FIGS. 4 and 5, a housing 31 comprising an aluminum die-cast case 31 a and a synthetic resin cover 31 b, and the inside of the housing 31 can be rotated. There is a movable body 40 that can be freely stored, and a housing 31 is attached to an automatic transmission, and the movable body 40 is fixed to a manual shaft 60 for shift switching that rotates in response to an operation of a shift lever. (For example, refer to Patent Document 1). That is, the movable body 40 rotates integrally with the manual shaft 60 according to the rotation of the shift lever.

可動体４０はマニュアルシャフト６０に固定される軸部４１と、軸部４１から突設されてケース３１ａの凹部３２で形成される空間内を回動する主体４２とを有し、締め付け用ナット５０を用いて軸部４１がマニュアルシャフト６０に締め付け固定される。なお、軸部４１には、締め付け用ナット５０の回り止めとして座金５１が装着されている。そして、ハウジング３１には軸部４１を回動自在に枢支する軸受孔３３が設けてある。また、詳細な構造は説明しないが、主体４２のカバー３１ｂに対向する側の面にはコイルばね４４で付勢された可動接点４３が複数個設けてあり、カバー３１ｂに植設された複数の帯状の固定接点３４に接離自在に弾接させてある。   The movable body 40 includes a shaft portion 41 fixed to the manual shaft 60, and a main body 42 that protrudes from the shaft portion 41 and rotates in a space formed by the recess 32 of the case 31a. The shaft portion 41 is fastened and fixed to the manual shaft 60 using A washer 51 is mounted on the shaft 41 as a detent for the tightening nut 50. The housing 31 is provided with a bearing hole 33 that pivotally supports the shaft portion 41. Although a detailed structure will not be described, a plurality of movable contacts 43 urged by a coil spring 44 are provided on the surface of the main body 42 facing the cover 31b, and a plurality of movable contacts 43 implanted in the cover 31b are provided. The belt-shaped fixed contact 34 is elastically contacted and separated.

複数の固定接点３４は可動体４０の回動中心に対して円弧状に設けてあって、パーキング、リバース等の各シフトポジションに対応する固定接点３４と、共通の固定接点３４とを備えている。つまり、この自動変速機用コントロールスイッチでは、シフトレバーの回動操作に応じて可動体４０が一体的に回動して、可動接点４３が固定接点３４と接触，開離することで切換出力としてポジション信号を得ている。   The plurality of fixed contacts 34 are provided in an arc shape with respect to the rotation center of the movable body 40, and include a fixed contact 34 corresponding to each shift position such as parking and reverse, and a common fixed contact 34. . In other words, in this automatic transmission control switch, the movable body 40 is integrally rotated in accordance with the rotation operation of the shift lever, and the movable contact 43 is brought into contact with and separated from the fixed contact 34 to provide a switching output. A position signal is obtained.

ところで、上記従来例のようにマニュアルシャフト６０に対して締め付け用ナット５０を用いて軸部４１を締め付け固定する構造に代わって、可動体４０の軸部４１にマニュアルシャフト６０を圧入固定する構造が一般に採用されるようになっている。この種の従来例として、図６及び図７に示すように可動体４０の軸部４１に貫設された挿通孔４１ａにばね体２０を収納し、ばね体２０に設けられた一対の保持部２１の間の空間にマニュアルシャフト６０の先端部を圧入することで各保持部２１が先端部に圧接して弾性的に保持するようにしたものがある。かかる従来例によれば、先の従来例のようにナット５０を締め付ける必要がないことから製造工程の簡素化が図れるとともにナット５０の締め付け不足やゆるみ等による不具合の発生を防ぐことができる。
特開平１１−４５６３６号公報 By the way, instead of the structure in which the shaft portion 41 is fastened and fixed to the manual shaft 60 using the tightening nut 50 as in the conventional example, a structure in which the manual shaft 60 is press-fitted and fixed to the shaft portion 41 of the movable body 40 is employed. Generally adopted. As a conventional example of this type, as shown in FIGS. 6 and 7, the spring body 20 is housed in an insertion hole 41 a penetrating the shaft portion 41 of the movable body 40, and a pair of holding portions provided in the spring body 20. There is one in which each holding portion 21 is elastically held in pressure contact with the distal end portion by press-fitting the distal end portion of the manual shaft 60 into a space between 21. According to such a conventional example, it is not necessary to tighten the nut 50 as in the previous conventional example, so that the manufacturing process can be simplified and the occurrence of problems due to insufficient tightening or loosening of the nut 50 can be prevented.

以下、本発明の実施形態を図１及び図２を参照して詳細に説明する。但し、基本的な構成は従来例と共通であるので、共通する部分には同一の符号を付して説明は省略する。   Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2. However, since the basic configuration is the same as that of the conventional example, common portions are denoted by the same reference numerals and description thereof is omitted.

本実施形態は、アルミダイカスト製のケース２と合成樹脂製のカバー３とをリベット（図示せず）で結合して組立てられる略扇形のハウジング１と、該ハウジング１の内部に回動自在に収められる可動体１０とを備えている。   In the present embodiment, a substantially fan-shaped housing 1 assembled by joining a case 2 made of aluminum die-casting and a cover 3 made of synthetic resin with a rivet (not shown), and is housed in the housing 1 so as to be rotatable. The movable body 10 is provided.

可動体１０は亜鉛ダイカスト製で一端に円筒形の軸部１２を有する主体１１を備え、主体１１のカバー３と対向する面（図２における下面）に設けられた凹所（図示せず）内にコイルばね１４によりカバー３側へ弾性付勢された３個の可動接点１５が収納される。軸部１２の構造は、軸部１２内において軸方向略中央から一端側（図１（ｃ）における左側）には軸方向に沿った平坦な面を有する一対の弦部１２ａが互いに平行する形で設けられており、その結果、弦部１２ａが設けられている部位ではマニュアルシャフトが挿通される挿通孔１２ｂが狭くなっている。また挿通孔１２ｂにはマニュアルシャフトを弾性的に保持するためのばね体２０が収納されてある。このばね体２０は弾性を有する板材を加工して形成されるものであって、幅細の半円環状に形成された主部２２と、主部２２の両端より主部２２の幅方向に沿って立ち上がる一対の保持部２１とを備えている。ばね体２０は、軸部１２の挿通孔１２ｂの一端側（図１（ｃ）における右側）から挿入され、一対の保持部２１をそれぞれ弦部１２ａの対向面に当接させるようにして軸部１２の挿通孔１２ｂ内に収納される。また、軸部１２の一方の端面（図２における上面）には、挿通孔１２ｂの周囲を囲むように４個の略直方体形状の指示片１３が等間隔に突設されている。   The movable body 10 is made of zinc die casting and includes a main body 11 having a cylindrical shaft portion 12 at one end, and in a recess (not shown) provided on a surface (lower surface in FIG. 2) facing the cover 3 of the main body 11. The three movable contacts 15 elastically biased toward the cover 3 by the coil spring 14 are housed. The shaft portion 12 has a structure in which a pair of chord portions 12a having a flat surface along the axial direction is parallel to each other from the substantially axial center to one end side (left side in FIG. 1C) in the shaft portion 12. As a result, the insertion hole 12b through which the manual shaft is inserted is narrow at the portion where the string portion 12a is provided. The insertion hole 12b accommodates a spring body 20 for elastically holding the manual shaft. The spring body 20 is formed by processing an elastic plate material, and has a main part 22 formed in a narrow semi-annular shape, and extends in the width direction of the main part 22 from both ends of the main part 22. And a pair of holding portions 21 that rise up. The spring body 20 is inserted from one end side (the right side in FIG. 1C) of the insertion hole 12b of the shaft portion 12, and the pair of holding portions 21 are in contact with the opposing surfaces of the chord portion 12a, respectively. The twelve insertion holes 12b are accommodated. Further, on one end surface (upper surface in FIG. 2) of the shaft portion 12, four substantially rectangular parallelepiped-shaped indicator pieces 13 are projected at equal intervals so as to surround the periphery of the insertion hole 12 b.

カバー３は一面が開口する扁平な略扇形に形成され、扇の要に相当する部分には可動体１０の軸部１２の一端側が挿通されて回動自在に枢支する軸受孔４が厚み方向に貫設されている。また、カバー３の内底面には一端部にそれぞれ固定接点１５ａ（図１（ｃ）参照）が設けられた帯板状の導電体（図示せず）がインサート成形されている。各固定接点１５ａは軸受孔４を中心にした同心円弧状に配設されており、ハウジング１内で可動体１０が具備する可動接点１５と対向させてある。また周壁で囲まれ筒状に形成されたコネクタ部１６がカバー３と一体に形成されており、コネクタ部１６の内底面には、複数の導電体の先端が複数列に突出されてコネクタ端子が形成してある。すなわち、ハウジング１に対する可動体１０の回動位置に応じて可動体１０に保持されている可動接点１５が各固定接点１５ａと選択的に接触・開離し、自動変速機のシフトポジションに対応したポジション信号がコネクタ部１６に接続された相手側コネクタを介して取り出されるのである。   The cover 3 is formed in a flat and substantially fan shape with an opening on one surface, and a bearing hole 4 that pivotally supports the end portion of the shaft portion 12 of the movable body 10 inserted through a portion corresponding to the center of the fan in the thickness direction. It is penetrated by. A strip-shaped conductor (not shown) having a fixed contact 15a (see FIG. 1 (c)) at one end is insert-molded on the inner bottom surface of the cover 3. Each fixed contact 15 a is arranged in a concentric arc shape with the bearing hole 4 as the center, and is opposed to the movable contact 15 provided in the movable body 10 in the housing 1. A connector portion 16 surrounded by a peripheral wall and formed in a cylindrical shape is formed integrally with the cover 3, and on the inner bottom surface of the connector portion 16, the tips of a plurality of conductors protrude into a plurality of rows and connector terminals are provided. It is formed. That is, the movable contact 15 held by the movable body 10 according to the rotational position of the movable body 10 with respect to the housing 1 selectively contacts and separates from each fixed contact 15a, and the position corresponds to the shift position of the automatic transmission. The signal is taken out via the mating connector connected to the connector portion 16.

ケース２はアルミダイカスト製で扁平な略扇形に形成され、カバー３と同様に扇の要に相当する部分には可動体１０の軸部１２の他端側が挿通されて回動自在に枢支する軸受孔５が厚み方向に貫設されている。また、ケース２の表面（図２における上面）における軸受孔５の周囲には４個の略直方体形状の指示部６が等間隔に突設されている。尚、ケース２には車体（あるいは自動変速機）への取付用の取付ネジが挿通されるネジ挿通孔１ａが設けてある。   The case 2 is made of aluminum die casting and is formed in a flat and substantially fan shape. Like the cover 3, the other end side of the shaft portion 12 of the movable body 10 is inserted into a portion corresponding to the main part of the fan 10 and pivotally supported. The bearing hole 5 is penetrated in the thickness direction. In addition, around the bearing hole 5 on the surface of the case 2 (upper surface in FIG. 2), four substantially rectangular parallelepiped indicating parts 6 are projected at equal intervals. The case 2 is provided with a screw insertion hole 1a through which a mounting screw for mounting to the vehicle body (or automatic transmission) is inserted.

上述のように構成される本実施形態は、以下のようにして組立てられる。カバー３の軸受孔４内に環状のオイルシール１７を収納するとともにカバー３の開口面に外形が略扇形の防水パッキン１８を配置し、コイルばね１４、可動接点１５、ばね体２０を取付けた可動体１０を収納する。次に、軸受孔５内に環状のオイルシール１９を収納したケース２をカバー３に被着し、可動体１０の軸部１２の他端側をオイルシール１９を通して軸受孔５に挿通させた状態でリベットによりケース２とカバー３を結合してハウジング１を組立てて本実施形態が完成する。そして、カバー３の側から軸部１２の挿通孔１２ｂにマニュアルシャフトを貫通させれば、断面形状が略長円形状に形成されたマニュアルシャフトの先端部がばね体２０の一対の保持部２１の間に圧入され、ばね体２０のばね力により保持部２１が圧接することでマニュアルシャフトの先端部を軸部１２に対して弾性的に保持させることができる。   The present embodiment configured as described above is assembled as follows. A ring-shaped oil seal 17 is accommodated in the bearing hole 4 of the cover 3, a waterproof packing 18 having a substantially fan-shaped outer shape is disposed on the opening surface of the cover 3, and a coil spring 14, a movable contact 15, and a spring body 20 are attached. The body 10 is stored. Next, the case 2 in which the annular oil seal 19 is accommodated in the bearing hole 5 is attached to the cover 3, and the other end side of the shaft portion 12 of the movable body 10 is inserted into the bearing hole 5 through the oil seal 19. Thus, the case 2 and the cover 3 are coupled by rivets to assemble the housing 1 to complete the present embodiment. Then, if the manual shaft is passed through the insertion hole 12b of the shaft portion 12 from the cover 3 side, the distal end portion of the manual shaft whose cross-sectional shape is formed in a substantially oval shape is the pair of holding portions 21 of the spring body 20. The distal end portion of the manual shaft can be elastically held with respect to the shaft portion 12 by being press-fitted in between and the holding portion 21 being pressed by the spring force of the spring body 20.

ところで、軸部１２に設けられた指示片１３は軸受孔５を通してハウジング１（ケース２）の表面に露出しており、マニュアルシャフトに連結された可動体１０がハウジング１に対して可動すると軸部１２も一体に回動し、ハウジング１の表面に露出した指示片１３がハウジング１の表面に沿って軸受孔５の周方向に移動（回動）することになる。一方、ハウジング１（ケース２）表面における軸受孔５の周囲には指示部６が設けられているため、図１（ａ）に示すようにマニュアルシャフトの軸方向からハウジング１を見た時に指示部６と指示片１３が同一直線上に位置すれば、ハウジング１に対する可動体１０の回動位置、すなわち、可動体１０が特定のポジション信号（例えば、ニュートラルに対応するポジション信号）を出力する状態にあることが容易に判別できる。   By the way, the indication piece 13 provided on the shaft portion 12 is exposed to the surface of the housing 1 (case 2) through the bearing hole 5, and the shaft portion is moved when the movable body 10 connected to the manual shaft moves relative to the housing 1. 12 also rotates integrally, and the indicator 13 exposed on the surface of the housing 1 moves (rotates) along the surface of the housing 1 in the circumferential direction of the bearing hole 5. On the other hand, since the indicating portion 6 is provided around the bearing hole 5 on the surface of the housing 1 (case 2), the indicating portion is viewed when the housing 1 is viewed from the axial direction of the manual shaft as shown in FIG. 6 and the pointing piece 13 are located on the same straight line, the rotational position of the movable body 10 relative to the housing 1, that is, the movable body 10 outputs a specific position signal (for example, a position signal corresponding to neutral). It can be easily determined that there is.

上述のように本実施形態では、シフトレバーの操作によってマニュアルシャフトが回動する際に可動体１０とともに軸部１２が回動し、さらに軸部１２が具備する指示片１３も回動するため、ハウジング１表面に設けられた指示部６と指示片１３との相対的な位置関係が可動体１０の回動位置に応じて変化することになり、ハウジング１に設けられた指示部６と軸部１２が具備する指示片１３によって部品点数を増やすことなく外観から可動体１０の回動位置を知ることができる。また、指示部６及び指示片１３をハウジング１（ケース２）と異なる色に着色すれば、指示部６及び指示片１３の視認性を向上することができ、自動変速機への取付作業の効率化、作業ミスの防止が図れるという利点がある。尚、本実施形態では指示部６及び指示片１３を略直方体形状に形成してあるが、これに限定される必要はなく、本発明の効果を奏するものであれば他の形状でも構わない。また本実施形態では指示部６及び指示片１３の個数はそれぞれ４個ずつであるが、本発明の効果を奏するものであれば、個数はこれに限定されるものではない。尚、複数の指示部６及び指示片１３を、マニュアルシャフトの軸方向からハウジング１を見た時に放射状となるように形成すると、視認性が向上して望ましい。   As described above, in the present embodiment, when the manual shaft is rotated by the operation of the shift lever, the shaft portion 12 is rotated together with the movable body 10, and the indicator piece 13 provided in the shaft portion 12 is also rotated. The relative positional relationship between the indicator 6 provided on the surface of the housing 1 and the indicator piece 13 changes according to the rotational position of the movable body 10, and the indicator 6 provided on the housing 1 and the shaft portion. The rotating position of the movable body 10 can be known from the appearance without increasing the number of parts by the pointing piece 13 included in the display 12. In addition, if the indication portion 6 and the indication piece 13 are colored in a different color from the housing 1 (case 2), the visibility of the indication portion 6 and the indication piece 13 can be improved, and the efficiency of the mounting work to the automatic transmission is improved. There is an advantage that it is possible to prevent mistakes and work errors. In addition, in this embodiment, although the instruction | indication part 6 and the instruction | indication piece 13 are formed in the substantially rectangular parallelepiped shape, it is not necessary to be limited to this and another shape may be sufficient as long as there exists an effect of this invention. In the present embodiment, the number of the instruction units 6 and the instruction pieces 13 is four each, but the number is not limited to this as long as the effect of the present invention is achieved. Note that it is desirable that the plurality of indicating portions 6 and the indicating pieces 13 are formed so as to be radial when the housing 1 is viewed from the axial direction of the manual shaft.

ところで、指示部６及び指示片１３はその寸法によって視認性が異なるので、指示部６及び指示片１３の寸法を変化させて視認性の確認を行った。その結果を図３に示す。指示部６及び指示片１３の寸法、すなわち指示部６及び指示片１３の幅（図３（ａ）上図における左右方向）と高さ（図３（ａ）下図における上下方向）を変化させたところ、図３（ｂ）に示すように、指示部６及び指示片１３の幅と高さは、それぞれ２ｍｍ以上、４ｍｍ以上であれば視認性が良好であり、発明の実施上望ましい。   By the way, since the visibility of the indication unit 6 and the indication piece 13 varies depending on the size thereof, the visibility is confirmed by changing the size of the indication unit 6 and the indication piece 13. The result is shown in FIG. The dimensions of the indicating unit 6 and the indicating piece 13, that is, the width (the horizontal direction in the upper diagram of FIG. 3A) and the height (the vertical direction in the lower diagram of FIG. 3A) are changed. However, as shown in FIG. 3 (b), the visibility is good if the width and height of the indicating section 6 and the indicating piece 13 are 2 mm or more and 4 mm or more, respectively, which is desirable in the practice of the invention.
