Definitions
- the present invention relates to a retaining structure that prevents one from slipping out of the other between two members.
- the present invention has been completed in view of the above circumstances, and it is an object to be solved to provide a retaining structure capable of effectively retaining the retaining pin itself even with a simple configuration.
- the through-holes provided in the two members and the retaining pins are not necessarily formed with such an accuracy that they are in close contact with each other, and it is normal that the portions that contact each other vary.
- the through hole 910 provided in the shift and select shaft 91 may be formed to be shifted from the through hole 920 provided in the inner lever (in FIG. 6). (Upper drawing)
- the retaining pin 93 is a slotted pin, and its diameter can be reduced according to the external force. A case where the through-holes 910 and 920 are biased upward in the drawing is assumed below for some reason.
- the tip diameter is reduced.
- the retaining pin 93 roughly follows the shape of the through-holes 910 and 920, the center swells upward in the drawing, and both ends are displaced downward in the drawing (FIG. 6).
- the retaining pin 93 and the through hole 920 of the inner lever 92 are in contact with each other at the part A and the part B on the left side of the drawing, and at the part C and the part D on the right side of the drawing.
- the magnitude and direction of the force applied to the retaining pin 93 depends on the magnitude and balance of the distance from the outer periphery of the fixed portion of the shift and select shaft 91 to the portion where the through hole 920 provided in the inner lever 92 contacts the retaining pin 93. It turns out that it is decided.
- the position where the retaining pin 93 and the through holes 910 and 920 are in contact with each other is limited to a narrow range, thereby controlling the force applied to the retaining pin and suppressing the retaining pin from coming off.
- Patent Document 2 does not intend to solve such a problem, the circumferential direction (direction perpendicular to the axial direction) of the shift-and-select shaft becomes longer as a through hole into which the retaining pin is inserted.
- the form which employs a long hole is disclosed. Even if the shift-and-select shaft is rotated by using a long hole in the circumferential direction, the retaining pin does not come into contact with the through hole formed in the inner lever, and it is estimated that no biasing force is applied to the retaining pin.
- a retaining structure according to the present invention that solves the above problems includes a first structure portion having a substantially cylindrical fixing portion, a second structure body having a fixing hole fitted to the outer periphery of the fixing portion, and A retaining pin disposed so as to connect the fixing portion and the second structure toward the radial direction of the fixing portion when the fixing portion is fitted in the fixing hole;
- the insertion hole into which the retaining pin provided in the second structure is inserted is a part on the radially inner side including a portion in contact with the outer periphery of the fixed portion, and a proximity portion close to the retaining pin, And a diameter-expanded portion that is a remaining portion from the outside and is larger in diameter than the adjacent portion so as not to be in close contact with the retaining pin.
- the range (blurring range) in which the portion where the inner wall of the insertion hole formed in the second structure comes into contact with the retaining pin is fluctuated is reduced.
- the force the force applied in the direction in which the retaining pin is pulled out
- At least one of the following configurations (2) to (4) can be added to the configuration (1) described above.
- the proximity portion is only a portion in contact with the outer periphery of the fixed portion. Since the portion of the insertion hole formed in the second structure that contacts the retaining pin can be defined in the length direction of the retaining pin, the force applied to the retaining pin can also be defined, and the retaining pin itself The force applied in the direction of withdrawal can be controlled appropriately.
- the retaining pin can be elastically deformed in the radial direction. Since the retaining pin can be expanded and contracted in the radial direction, the range in which the retaining pin can contact the inner wall of the insertion hole is expanded, and an imbalance of the force applied to the retaining pin can be suppressed.
- Such a retaining pin is known as a slotted pin.
- the fixing portion is in close contact with the retaining pin at least in the vicinity of the fixing hole.
- a bending moment is hardly generated in the retaining pin, and a force in the direction in which the retaining pin is removed is applied. Can be suppressed.
- FIG. 3 is a partially enlarged view of a shift and select shaft and an inner lever that employ a retaining prevention structure according to an embodiment. It is sectional drawing when there is a shift
- the retaining structure for preventing slipping of the present invention will be described in detail based on the following embodiments.
- the retaining structure according to the present embodiment prevents the first structure and the second structure from being unfixed in the structure in which the first structure and the second structure are fixed by a retaining pin. Therefore, it has a retaining structure that prevents the retaining pin from coming off.
- description will be made based on what is adopted as a component in a transmission mounted on a vehicle.
- the first structure is a shift and select shaft
- the second structure is an inner lever.
- the shift and select shaft constitutes a part of a transmission mounted on the vehicle. For example, in a manual transmission as a transmission, a shift operation is performed by converting the movement of a shift lever into an axial movement and a rotation direction of a shift and select shaft.
- an inner shaft 2 as a second structure is fixed to a shift and select shaft 1 as a first structure.
- the shift and select shaft 1 is a rod-shaped member and has a cylindrical fixing portion 11.
- the inner lever 2 is formed with a fixing hole 2a into which the fixing portion 11 is inserted.
- the outer peripheral surface 12 of the fixing portion 11 and the inner peripheral surface 24 of the fixing hole 2a are formed with splines (not shown) that can mesh with each other, and in the engaged state, the shift and select shaft 1 and the inner lever 2 are in the axial direction. Even if the relative movement is freely possible, the relative rotation is impossible.
- the inner lever 2 has a tip portion 29 engaged with a fork head (not shown) to move a fork shaft provided with the fork head.
- Insertion holes 10 and 20 are formed so that the retaining pin 3 can be inserted through the shift and select shaft 1 and the inner lever 2 in combination.
- the insertion holes 10 and 20 have a circular cross section.
- the retaining pin 3 is a pin formed by rolling a plate-like body so that the cross section is C-shaped, and is a pin whose diameter can be elastically deformed and reduced according to the inner diameter of the inserted hole. 10 and 20, the relative movement in the axial direction between the shift and select shaft 1 and the inner lever 2 is restricted.
- the insertion hole 10 has an inner diameter that is slightly smaller than the outer diameter of the retaining pin 3 before insertion, and the retaining pin 3 is reduced in diameter by being inserted and is in close contact with the inner wall of the insertion hole 10.
- the insertion hole 20 has a proximity portion 22 that can be in close contact with the retaining pin 3 at a location close to the outer peripheral surface 12 of the shift and select shaft 1.
- the proximity portion 22 corresponds to the close contact portion of the present invention.
- a part of the proximity portion 22 may be in close contact with the proximity portion 22 and the retaining pin 3.
- the upper limit of the length in the axial direction of the portion closely contacting the retaining pin 3 as the proximity portion 22 is a value such as 1 mm, 0.75 mm, 0.5 mm, 0.25 mm, 0.1 mm, 0.05 mm, or the proximity portion. Values such as 0.5 times, 0.4 times, 0.3 times, 0.2 times, 0.1 times, and 0.05 times the diameter of 22 can be adopted. By reducing this value, it is possible to narrow the range in which the portion where the retaining pin 3 and the proximity portion 22 are in close contact with each other occurs. On the contrary, increasing the strength improves the strength of the proximity portion 22. it can.
- the insertion holes 10 and 20 are shifted so that the retaining pin 3 can be in close contact with the inner wall of the proximity portion 22.
- Parts other than the proximity part 22 of the insertion hole 20 constitute an enlarged diameter part 21 having an inner diameter larger than that of the proximity part 22.
- the retaining pin 3 is reduced in diameter at the proximity portion 22. Therefore, the retaining pin 3 does not contact the inner wall of the enlarged diameter portion 21.
- the difference in inner diameter between the proximity portion 22 and the enlarged diameter portion 21 is depicted very large for ease of understanding, but a slight difference in inner diameter is necessary in order to achieve the effect in the present embodiment. Often it is sufficient. For example, when the size of the displacement that is expected to occur at the maximum in the insertion holes 10 and 20 is small, the inner diameter difference can be reduced. -Effects Since the retaining structure of the present embodiment has the above-described configuration, the following effects can be achieved.
- the shift and select shaft 1 is fitted by a spline provided in the fixing portion 11 and the fixing hole 2a of the inner lever 2, and the relative rotation of the shift and select shaft 1 in the direction around the axis is limited.
- the relative movement between the shift and select shaft 1 and the inner lever 2 is restricted by inserting the retaining pin 3.
- FIG. 5 shows a state in which the insertion hole 10 provided in the shift and select shaft 1 is formed so as to be shifted upward from the insertion hole 20 provided in the inner lever 2, the explanation is easy. Thus, the size of the shift is exaggerated. Even if there is actually almost no deviation, the effects of the present embodiment can be exhibited even when there is a deviation that can change the degree of contact between the insertion holes 10 and 20 and the retaining pin 3.
- the insertion hole 10 is displaced from the insertion hole 20 in the upper part of the drawing, so that the retaining pin 3 inserted has a central part moved upward in the drawing and both end parts moved downward in the drawing. As a whole, the center portion is bent so as to protrude upward in the drawing.
- the proximity portion 22 By adopting the configuration of the present embodiment, even if the retaining pin 3 is bent, a portion where the retaining pin 3 and the inner peripheral surface of the fixing hole 2a provided in the inner lever 2 are in contact is represented by the proximity portion 22.
- the distance from the outer periphery of the fixing portion 11 of the shift and select shaft 1 is substantially constant regardless of the degree of bending of the retaining pin 3 (that is, the displacement of the insertion holes 10 and 20). it can. That is, the variation in the positions A to D can be reduced depending on how far the proximity portion 22 is formed from the outer periphery of the fixing portion 11 and how much the proximity portion 22 is formed from the outer periphery of the fixing portion 11.
- the proximity portion 22 is preferably formed so as to be in contact with the outer periphery of the fixed portion 11 from the viewpoint of ease of manufacture.
- the insertion hole 20 has a circular cross section in the direction perpendicular to the axial direction, it is easier to process than the long hole.
- the retaining structure according to the present invention makes it possible to reduce the range (blurring range) in which the part where the inner wall of the insertion hole comes into contact with the retaining pin can be changed, and to reduce the contact part.
- the force derived from the bending moment applied to the retaining pin due to the balance (the force applied in the direction in which the retaining pin is removed) can be reduced.

Abstract
Description
ここで抜け止めピンは貫通孔に圧入されることで2つの部材の間を確実に連結する。その場合に抜け止めピンは径方向に拡大縮小可能なスロテッドピンが採用されることがある(特許文献1など)。
(1)上記課題を解決する本発明の抜け止め防止構造は、略円筒形の固定部をもつ第1構造部と、前記固定部の外周に嵌合する固定孔をもつ第2構造体と、前記固定部が前記固定孔に嵌合したときに前記固定部の径方向に向け、前記固定部及び前記第2構造体の間を接続するように配設される抜け止めピンとを有し、
前記第2構造体に設けられた前記抜け止めピンが挿入される挿入孔は、前記固定部の外周に接する部分を含む径方向内側の一部であって前記抜け止めピンに近接する近接部と、外側からの残部であって前記抜け止めピンに密着しないように前記近接部よりも拡径されている拡径部とをもつ。
(2)前記近接部は前記固定部の外周に接する部分のみである。第2構造体に形成された挿入孔における抜け止めピンが接触する部位が、抜け止めピンの長さ方向において規定できるため抜け止めピンに加わる力も規定することが可能になって抜け止めピン自身が抜ける方向に加わる力を適正に制御可能になる。
(3)前記抜け止めピンは径方向に弾性変形できる。抜け止めピンが径方向に伸縮できることによって抜け止めピンが挿入孔の内壁に接触できる範囲が拡がって抜け止めピンに加わる力の不均衡が抑制できる。このような抜け止めピンはスロテッドピンと称されるものが知られている。
(4)前記固定部は少なくとも前記固定孔近傍にて前記抜け止めピンに密着する。固定部に形成された挿入孔についても第2構造体に接する部位である固定孔近傍にて接触させることにより抜け止めピンに曲げモーメントが発生し難くなり抜け止めピンが抜ける方向への力が加わることが抑制できる。
・作用効果
本実施形態の抜け止め防止構造は上述の構成をもつことから以下の作用効果を発現できる。
